Description

  The present invention relates to a siphon water feeding device and a water feeding method for feeding water in a reservoir in a high water level area to a low area located lower than the high water level area, and further siphon water feeding apparatus capable of discharging earth and sand along with the water feeding. And a siphon water feeding method.

  Large ponds and lakes are created by damming a large amount of water with earth and sand, such as “earth and sand dams (natural dams)” caused by natural disasters such as earthquakes, and “glacial lakes” caused by glacial water that has started to melt due to global warming. Is forming. However, since the earth and sand that has been dammed only dams the lake by a natural collapse or the like, there is always a great risk that the dammed earth and sand will collapse and become debris flow. In order to avoid such danger, measures to prevent debris flow by draining the water accumulated in ponds and lakes are being studied. In this case, it is necessary to drain the water of the pond or the lake without causing the water to overflow directly onto the dammed earth and sand to lower the water level of the reservoir upstream of the dam. There are two methods for lowering the water level: draining only the reservoir water and draining the sediment deposited on the bottom of the dam lake together with drainage to lower the ground level of the bottom of the lake.

  However, in the case of drainage by a submersible pump, if a large amount of drainage work is urgently required due to a sediment disaster, the drainage work is performed by multi-strip piping. In this case, a large number of large-diameter submersible pumps of 30 to 40 are required for drainage work in one place, and hundreds of submersible pumps and water supply pipes are required when there are a plurality of disaster sites. In carrying out this work, there is a problem that it is extremely difficult to procure a large amount of temporary equipment such as large-diameter submersible pumps and generators and transport them to earth and sand dams and glacial lakes. In addition, even if the installation of drainage equipment such as submersible pumps can be completed, a large amount of electricity is required to continue operation of these, but in order to operate the generator for power generation, every day For this reason, there has been a problem that a large amount of fuel (diesel oil) must be periodically carried in and refueled or a large amount of fuel must be consumed. In order to solve this problem, it has been studied to use a siphon action that does not consume much fuel or electricity. However, the conventional techniques and devices that activate the siphon action by pouring water require that each device or method has an opening / closing device in the water absorption part and the drainage part of the water pipe. After filling the entire water pipe by pouring water from the highest point of the water pipe, both opening and closing devices were opened. According to this conventional device and method, it is necessary to open and close the opening and closing devices of the water inlet and the drain. Since the water intake port is in the water, it is difficult to get close to it and it is extremely dangerous and difficult, and the opening and closing of the discharge port is done by manpower by going down the dangerous slope and it was very dangerous work. There has been a demand for a siphon water feeding device and a water feeding method by a siphon activation method that does not require such a large amount of equipment and can omit dangerous work.

  In addition, as a method of removing sediment accumulated on the bottom of a reservoir such as a dam, there is a method of draining sediment together with water using a pump drainage operation. However, since this method uses an earth-and-sand device with a pump that operates using electricity, use in areas without electricity in mountainous areas may bring in a generator or require refueling work. There was a problem. Therefore, since the method of excavating and transporting with heavy machinery etc. is cheaper and more efficient, the current situation is that the sand removal method associated with pump drainage has not been implemented. Sand and sand are accumulated in dams and reservoirs and are no longer transported downstream, causing coarsening in the riverbed and affecting the habitat of living organisms, and sand is no longer supplied from the river mouth to the beach. The shoreline itself has been scoured and other damage has occurred.

In the text below, “water supply” includes the contents of “sediment sand with water supply”.

The present invention adopts the following means in order to achieve the main object described above.
The siphon water feeder of the present invention is
A siphon watering device that moves water in a reservoir in a high water level area or water and earth and sand to a low area located lower than the high water level area,
A pipe-shaped member capable of maintaining a cross-sectional shape, constructed between the low region and the high water level region, and having a water intake port opened on the high water level region side, and an outlet port also opened on the low region side A water pipe with
A water injection / merging member provided with a water injection part that is connected to the water supply pipe and includes at least one water injection opening / closing device that can be connected to the water supply device, or a water injection part to which the water injection opening / closing device can be attached. Siphon water supply device.

  The siphon water feeding device of the present invention is a pipe constructed between a storage section in a high water level area and a low area, and feeds water from the storage section in the high water level area to the low area by siphon action. is there. In the siphon water supply device according to the present invention, since the discharge port on the low area side (hereinafter also referred to as “downstream side”) is always open, the downstream end is closed to collect the priming water in the entire water supply pipe. The siphon cannot be activated. In other words, the conventional siphon activation method is generally a method in which the opening and closing device provided on the discharge port side is closed and water is injected so as to gradually fill the water pipe, and the air in the water pipe is exhausted from the water injection section. It was. However, the siphon water feeding device according to the present invention pours water from the water pouring part provided in the water pouring / merging member, feeds water only in the direction of the discharge port, and the inside of the water feeding pipe only downstream from the water pouring / merging member becomes full. A sufficient amount of water will be poured from the water injection section. That is, the water in the water supply pipe is pushed out to the discharge port on the downstream side with the water to be injected, and the water supply pipe on the downstream side is filled with water from the water injection junction member. By closing the water injection unit opening / closing device after the full water condition has been confirmed, the air in the upstream water supply pipe is drawn and moved to the downstream side when water is continuously drained from the discharge port. Correspondingly, the water in the high water area is sucked into the water pipe. The drawn water and air are mixed in the middle to become water turbid with air and discharged from the discharge port, and the siphon action can be activated when a certain amount of water is sucked from the water intake port. Then, when the water in which the air is turbid is completely discharged, the water can be discharged by a complete siphon action. Thus, according to the present invention, the siphon action can be activated even though the water suction port is open and the discharge port is also open. Thus, the siphon activation method, siphon water feeding device and water feeding method, which can omit the opening / closing operation of the water suction port and the discharge port, which are dangerous operations due to human power described above. Moreover, it can be used also as an apparatus which sucks earth and sand together with water and simultaneously discharges sedimentary soil by the siphon action of the present siphon water feeding apparatus.

  In this way, the water supply pipe once activated with the siphon action can supply a large amount of water in the reservoir to the low area by the potential energy by the siphon action. At the same time, after the water pipe is full, no power is required, so there is no need to carry in fuel or supply fuel. Thereby, it is possible to greatly reduce the installation cost and water supply cost of the siphon water supply device. In addition, many workers do not have to do dangerous work, and it is no longer necessary to reside on site for maintenance of equipment and drainage work, so secondary disasters can be prevented by monitoring from a safe place. .

  In the siphon water supply device of the present invention, the position where the water injection confluence member provided with the water injection portion is attached is upstream of the highest point of the installed water supply pipe and lower than the highest point in the case of a siphon water supply device equipped with power such as electricity. Even in the position, priming water can be forcibly injected into the water supply pipe by the water supply device, and the air in the water supply pipe can be discharged from the discharge port on the downstream side. On the other hand, when the water storage tank is used as a water supply device, it is necessary to pay attention to the height and volume of the water storage tank, and the volume of the water storage tank is higher than the highest point of the laid water supply pipe on the downstream side from the water injection junction member. The siphon can be activated if it has a volume greater than the volume in the water pipe. According to this facility method, the facility form is the same as when the reservoir tank is installed at a position where the installation height of the reservoir tank is higher than the highest point of the water pipe. Moreover, the same equipment configuration can be obtained even if a storage tank is provided on a scaffolding or a foundation by changing the part of the storage tank up to the highest point of the water pipe. That is, it is only necessary that the siphon action can be started by injecting priming water from the water injection portion of the water injection junction member connected to the water supply pipe. The amount of water that can be injected from the water injection section into the water supply pipe becomes a `` priming water '' in a full state, and the amount of water that can be discharged from the discharge port by drawing the air in the upstream water supply pipe downstream. That's fine.

  Further, in the siphon water feeding device according to the present invention, the water injection / merging member includes a water injection part into which water from the water feeder is injected, a water absorption part into which water from the storage part is absorbed, and the water injection part or the water absorption. A water supply section that discharges water from the section, and is formed in an approximately T-shaped or approximately Y-shaped shape in which the water absorption section and the water injection section merge. It may have a switching valve capable of switching between the flow of water and the flow of water from the water absorption part side. By adopting such a configuration, the flow of water from the water injection section can be prevented from flowing to the water absorption section on the high water level region side, and water can be reliably injected into the discharge port on the downstream side. Therefore, the air in the water supply pipe on the downstream side of the water injection / merging member can be easily discharged (extruded) from the discharge port. Moreover, even when the water injection / merging member is installed at a lower position upstream from the highest point, the water injected into the water injection / merging member flows to the water feeding part without flowing to the water absorption part on the high water area side by the provided switching valve. Since it passes through the highest point and is discharged to the discharge port on the low area side, the siphon action can be activated.

  Furthermore, in the siphon water supply device according to the present invention, the water supply device may be a water storage tank capable of storing sufficient water to fill the water supply pipe on the downstream side from the water injection junction member. In order to continuously supply water by siphon action, sufficient siphon action cannot be caused unless the entire water supply pipe having an open discharge port is filled with water at a time. Therefore, when the water supply pipe is filled with a pump or the like, a pump having a corresponding operating force is required. Therefore, once the air in the water supply pipe is pushed out at once and stored in a water storage tank having a sufficient amount of water to fill the water supply pipe, the water is supplied to the water supply pipe at once through the water injection portion provided in the water injection junction member. The water pipe was filled with water while pushing the air in the water pipe to the discharge port on the downstream side. In order to store water in the water storage tank itself by using the water storage tank, it is not necessary to store a large amount of water at once. Therefore, even if water is stored with a pump with small electric power, or the same operation is performed using another small siphon-type siphon water supply device having the same mechanism as the present invention, water is stored in the water storage tank. Good.

  Furthermore, in the siphon water supply device of the present invention, the water supply device may be a water supply device that is driven by power of a drainage pump vehicle, a submersible pump, a fire engine, or the like. By adopting such a configuration, it is possible to discharge (extrude) the air in the water supply pipe from the discharge port more quickly and to fill the downstream water supply pipe with water.

  Furthermore, in the siphon water supply device according to the present invention, the length of the pipe filled with water injected from the water injection portion of the water injection junction member is lower than the water surface position of the storage portion on the high water level side of the water supply pipe. It may be longer than the distance to the position of the water pipe at the same height on the side. By adopting such a configuration, after filling the water supply pipe from the water injection section to the discharge port with water, the downstream side of the same height from the water supply pipe at the high water level by the air in the water supply pipe to be drawn in It becomes possible to draw water more than the distance to the position of the water pipe. Thereby, the siphon action can be activated at least on the high water level side of the water supply pipe. By this activated siphon action, water is further poured into the water supply pipe from the reservoir in the high water level region, and the siphon action is activated in the entire water supply pipe.

  Furthermore, in the siphon water supply device according to the present invention, the length of the pipe filled with water injected from the water injection portion of the water injection junction member is lower than the water surface position of the storage portion on the high water level side of the water supply pipe. It may be twice or more the distance to the position of the water pipe at the same height on the side. By adopting such a configuration, when the water injection opening / closing device communicating with the water injection unit is closed from the state where the downstream side from the water injection unit is full, the water drawn from the water intake port has a certain loss due to turbidity with air, etc. Even if it is a case, a siphon effect | action can be started reliably.

  Furthermore, in the siphon water supply device according to the present invention, the difference in height between the water level of the reservoir on the high water level side and the highest position of the piped water supply pipe = the head may be 7 m or less. As a result of the inventor's experiment, it has been found that when the head is set to 7 m or less, the operation of the siphon can be stably functioned and the maximum drainage amount can be maintained. That is, by setting to such a range, the maximum amount of water can be drained by the siphon action most effectively.

  Furthermore, in the siphon water supply device according to the present invention, the water supply pipe may be provided with a plurality of air valves for adjusting the head difference. By adopting such a configuration, even if the water level on the high water level side fluctuates up and down, the length of the water supply pipe is re-installed so that the optimum head difference is achieved according to the head. The siphon water feeding device having the optimum water head difference can be provided by performing the opening / closing operation so that the water head difference adjusting air valve provided in the water feeding pipe has the optimum water head difference.

  Furthermore, in the siphon water supply apparatus according to the present invention, a flexible hose may be connected to the water supply pipe on a lower region side than a reference head difference that can secure a maximum drainage amount. If the inner section of the water pipe is crushed by atmospheric pressure or external pressure, etc. until the position where the maximum discharge can be secured by the siphon action, the maximum discharge quantity of water cannot be discharged or the siphon action May not start. However, below the position where the optimum water head difference of the siphon action is below, even if a flexible hose is used, the water pressure flowing down from the upstream part by the siphon action is likely to be crushed by atmospheric pressure etc. Lower.

  Furthermore, the siphon water feeder concerning this invention WHEREIN: The said flexible hose may be connected to the downstream from the position which is the same or lower than the height of the water surface of the storage part of a high water level area.

  Furthermore, in the siphon water supply device according to the present invention, the water intake port that absorbs the water of the storage portion in the high water level area into the siphon water supply device has a mesh size less than the area of the water intake port so as to cover the periphery of the water intake port. There may be provided a dust suction preventing member. By adopting such a configuration, dust larger than the mesh of the dust suction preventing member is prevented from being sucked into the water supply pipe.

  Furthermore, in the siphon water supply device according to the present invention, the water supply pipe is disposed in a cylindrical member made of a flexible material and in the cylindrical member, and is formed in a spherical shape, a football shape, or a conical shape at the tip. An expansion spring-like member having a diameter slightly smaller than the inner diameter of the tubular member capable of maintaining the inner cross-sectional shape having the tubular member expanding portion may be provided. Since the expansion spring-like member has a cylindrical member expansion portion formed in a spherical shape, a football shape or a conical shape at the tip, the expansion portion of the cylindrical member is caused by water poured from behind the expansion spring-like member. By pushing forward in the downstream direction and proceeding through the cylindrical member, the extension spring-like member is arranged in the water supply pipe and can be made a water supply pipe that is not easily crushed. In addition, the space | interval of an expansion spring-like member is expanded, it is cut off from an expansion-spring member at a point where the expansion-spring member has extended moderately, and again passes through the inner diameter of the second expansion spring-like member previously provided downstream. Even if it is a water supply pipe having a structure in which the downstream portion of the expansion spring-like member is pulled and the cylindrical member expansion portion is pushed in the downstream direction, and if necessary, the expansion spring-like member and the subsequent portions are spread out on the inner cross section of the cylindrical member. Good.

  Further, in the siphon water feeding device according to the present invention, the water tank assembly member is provided with a water injection opening / closing device, and the water injection opening / closing device is provided with a water flow adjustment valve, and the water flow adjustment opening / closing device. The valve is an on-off valve that adjusts the amount of water discharged from the water storage tank. A fixed part is provided on a part of the outer periphery of the opening of the water tank assembling member so that it can be rotated by a hinge. A pulley may be provided. By adopting such a configuration, it is possible to adjust the supply, stop, and amount of water poured from the water feeder. Further, in the siphon water feeding device according to the present invention, the fixing portions are respectively provided at the centers of the water injection opening and closing devices, and are fixed so as to be rotatable so that the outside of the water flow amount adjusting on-off valve is opened and closed. Also good. Furthermore, in the siphon water supply device according to the present invention, the siphon water supply device can be attached to the water supply device, is formed in a cylindrical shape as a whole, has flanges that can be attached to the water supply device at both ends thereof, and has a cylindrical interior. May have an on-off valve whose water amount can be adjusted by a cylindrical adjustment lever. Moreover, the shape of the on-off valve for adjusting the amount of water flow may be a flat plate or a hemisphere.

Furthermore, in the siphon water supply device according to the present invention, when the multi-strip pipe is to be laid, the siphon water supply device is laid between the above-described siphon water supply device and the high water level storage section and the low region, A water injection and merging member, a water injection opening and closing device, and a water feeder machine, and one or two or more second siphon water feeders without a water feeder machine,
Furthermore, in the siphon water supply device according to the present invention, after the siphon water supply function of the siphon water supply device is operated, the water supply function of the siphon water supply device is used to inject water from the water injection unit of the water injection confluence member of the second siphon water supply device, Of the water supply pipes of the 2 siphon water supply device, after filling the water supply pipe downstream from the water injection and confluence member, the water injection opening and closing device provided in the water injection and confluence member is closed and the second siphon water supply device operates the water supply function by siphon action It may be. When the siphon action of the first siphon water supply device is activated and then another second, third and subsequent siphon water supply devices are activated by performing the same operation, electricity is used in this way. The drainage device after the second siphon water supply device may be activated without any problem.

  Furthermore, in the siphon water supply device according to the present invention, the water injection opening / closing device provided at the water injection portion of the water injection port merging portion of the siphon water supply device is connected to the water injection unit and the water supply device at both ends of a flexible second hose such as a sunny hose. You may use what is equipped with. As a result, when the water injection from the water feeder stops, the water in the flexible second hose, such as a sunny hose, is sucked into the water flowing down the water supply pipe and at the same time is crushed and blocked at atmospheric pressure to automatically close the switchgear. Since this is the same phenomenon as closing the door, the opening / closing operation can be omitted. You may equip the flexible 2nd hose part, such as the sunny hose used as the said water injection switchgear, with the instrument which pinches | interposes a 2nd hose part. As a result, the closed part of the closed flexible hose can be kept closed, so that the phenomenon of air entering the water injection part will not occur even if the water feeder is disconnected from the connection part provided on the flexible hose. It may be.

  Furthermore, in the siphon water supply device according to the present invention, the connection portions provided at both ends of the water supply pipe and the flexible hose may be connected using connection clips. When connecting by this, conventionally, the connecting parts of the water pipes to be connected are overlapped to align the positions of the holes, and conventionally, the bolts are inserted into the overlapped holes, and the work is fixed by tightening with nuts or the like from the opposite side. However, instead of this, after aligning the positions of the holes between the connection parts of the water pipe and inserting the insertion part of the connection clip into the hole, the two clipped parts of the connection clip are simultaneously stacked It can be fixed in a short time by the method of hitting with a hammer etc. and fixing it, and the thickness of the connection part was 10mm or more when using bolts and nuts, but the connection clip was used. In this case, the thickness of the connector is about 5 mm, so that the single unit weight of the connecting portion is reduced, leading to an improvement in the efficiency of human-powered transportation.

  Furthermore, in the siphon water supply device according to the present invention, the water inlet of the water supply pipe disposed in the storage portion in the high water level area may always be open. The siphon water supply device according to the present invention does not need to be opened / closed by providing an opening / closing device or the like at the water inlet, and may always be opened. Thereby, the operation | work which provides the member which opens and closes to a water inlet can be skipped.

  Furthermore, in the siphon water supply device according to the present invention, the water inlet is provided with a screw that is rotated by the flow of the sucked water, and stirring the sedimentary soil such as a lake bottom or a river bottom underwater by the rotation of the screw. The deposited soil and water may be absorbed together from the water inlet. As a result, by rotating the screw using the energy of the water flow at the time of water absorption from the water intake port, the work of stirring the deposited soil with the conventional stirring device using electricity does not use electricity. Work can be done.

  Further, in the siphon water supply device according to the present invention, a plurality of water supply pipes having the water intake port are arranged, and the water intake port includes a drive water intake port having a screw and a water intake port for water absorption mainly for water absorption, It may be one that absorbs water together with the deposited soil agitated from the water intake port other than the drive water intake port while stirring the sediment soil deposited on the lake bottom or river bottom by rotating the screw. According to this, since the water absorption part for stirring the sedimentary soil and the drive water inlet for rotating the screw are separated, the probability that the sedimentary soil that is agitated in the water and floats is absorbed while colliding with the screw is reduced. The effect of preventing damage can be exhibited.

  Further, in the siphon water supply device according to the present invention, a plurality of water supply pipes having the water intake port are arranged, and the water intake port includes a drive water intake port having a screw and a water intake port for water absorption mainly for water absorption, The water intake port for water absorption includes a member for agitation of sedimentary soil that rotates through an interlocking member, which is obtained by rotating the screw of the water absorption part for driving. It may be one that absorbs water together with the sedimented soil agitated from the water intake port while agitating the sedimented soil deposited in the water. According to this, water absorption of sedimentary soil that is agitated in water and floats is performed at the water intake port, so there is a high probability of absorbing suspended soil from the drive water intake port located away from the water intake port. Since it decreases, it becomes a structure which greatly helps to prevent damage to the screw rotating at the water intake for driving.

  Furthermore, the siphon water supply apparatus concerning this invention WHEREIN: The screw cover which prevents the flow of water from between a screw and a water inlet may be provided in the outer peripheral part of the said screw. By adopting such a configuration, the flowing water flowing from the front of the screw into the water inlet normally hits the screw, rotates the screw and then flows into the water inlet, so that the screw can be efficiently rotated. It is possible to prevent the rotation efficiency of the screw from being reduced by reducing the amount of water hitting the screw by passing a part of the screw between the screw and the water inlet without flowing into the screw and flowing into the water inlet.

  Furthermore, in the siphon water feeding device according to the present invention, the water inlet may be characterized in that an opening surface is formed obliquely upward. By adopting the shape that the opening surface of the water intake port faces diagonally upward, when the water intake port is installed in the reservoir, the water intake port can easily be directed diagonally upward. Inhalation can be reduced.

  Furthermore, in the siphon water feeding device according to the present invention, the water inlet has an opening / closing lid, the opening / closing lid has a float attachment part for connecting the float, and when the water level rises, the water level is opened by the float. An opening / closing lid attached to the opening with a hinge may be formed so as to close when lowered. By adopting such a configuration, the open / close lid connected to the water inlet with a hinge rises when the water level rises, so the float also rises, so the open / close lid can be pulled up and opened to the extent that the open / close lid cannot be pulled up. When the door is lowered, the open / close lid closes the water inlet. Due to this effect, when the water level exceeds a certain level, the lid is opened and water supply is started or sustained.When the level falls below a certain level, the lid closes due to its own weight, so water absorption stops and the water supply pipe remains full. Water supply can be automatically stopped in the state of. Since the inside of the water supply pipe is stopped in a full state, when the water level rises above a certain level, the opening / closing lid is lifted and opened to automatically restart the water supply operation.

  Furthermore, in the siphon water supply device according to the present invention, when the water inlet is inserted at an angle at which the tip of the water inlet pierces the lake bottom or river bottom when the water inlet is inserted into the lake bottom or river bottom, A cover member that covers at least the bottom surface side of the water inlet may be provided to prevent the sediment from being sucked in. By adopting such a configuration, when the tip of the water inlet is thrown into the lake bottom or river bottom, even if the tip is thrown at a right angle or obliquely with respect to the bottom, the cover portion is in contact with the bottom. Since the water inlet is not in direct contact with the bottom surface, it can be installed with the water inlet open, and this effect causes the water inlet to be clogged by dripping in water and pebbles rapidly from the water inlet. The water supply operation can be carried out while absorbing newly flowing out water and earth and sand in this state.

  In the water supply method according to the present invention, a flexible hose is connected downstream from a position equal to or lower than the height of the water surface of the reservoir in the high water level region on the upstream side downstream from the highest point of the water supply pipe. In the siphon water supply device, the air in the water supply pipe is discharged from the water supply pipe by using a vacuum pump instead of the water supply device from the water injection part of the water injection joining member connected to the highest point of the water supply pipe. The pressure in the water pipe is reduced to suck the water in the reservoir in the high water level area into the water pipe, and the water sucked in by continuing to discharge air passes through the highest point. The flexible hose flows down to the downstream side of the water supply pipe and the water is collected at the position where the flexible hose is bent and closed due to the pressure reduction effect of the vacuum pump. A water supply wherein the operating the siphon action by flowing down along with the air remaining in the water supply pipe contain scan the bent portion highest point of the water supply pipe to begin pushing stretched flow down. By adopting such a configuration, it may be possible to easily operate the siphon action.

  When using the siphon water supply device according to the present invention, it is a connection auxiliary member for connecting and passing water through connecting portions of water supply pipes that have different diameters and cannot be connected to the siphon water supply device, and is flexible and has a pressure of 7 or more Insert water pipes with different diameters from the openings on both sides of the cylindrical member made of a material that can withstand the water pressure of the water, and feed water from the outside of the cylindrical member at the neck of each water pipe with the connecting parts facing each other You may have the connection auxiliary member characterized by tightening with the fastening member which fastens a pipe together. When using the siphon water supply apparatus according to the present invention, in order to enable the use of the siphon water supply apparatus even when there is only a water supply device having a different diameter from the water supply pipe of the present apparatus, the connection between the water pipes of different diameters is possible. There should be an auxiliary member. For example, the Ministry of Land, Infrastructure, Transport and Tourism's disaster dispatching drainage pump vehicle has multiple types of water pipe diameters, and the submersible pumps owned by construction companies near the site where the disaster occurred also have multiple types of diameters. Even if you try to inject water from the water injection part of the water injection / merging member using the water supply device that arrived at the earliest, if the diameter of the water injection part of the submersible pump, water pipe, or water injection / merging member is different, it cannot be connected and cannot be drained become. Therefore, in order to perform the drainage operation even if the diameter of the water injection part of the water supply device, the water supply pipe, or the water injection / merging member is different, an auxiliary member that connects and uses the members of different diameters is necessary. This auxiliary member is formed into a cylindrical shape by a flexible material that is strong in tensile strength, and water injection pipes of water supply devices or water injection portions of a water injection confluence member are inserted from both sides thereof, so that not only the water injection portion but also the diameter of the water injection portion is inserted by this member. It can also be used for connecting parts of different water pipes.

First, in describing embodiments of the siphon water feeding device and the water feeding method of the present invention, the technical idea of the present invention will be described. The siphon water feeding device of the present invention is installed between the storage section 90 in the high water level area and the low area, and supplies water from the high water level storage section 90 to the low area by siphon action. Yes, the siphon action is activated using a siphon water supply device in which the water inlet in the high water level region is open and the discharge port on the low region side is always open. Originally, the conventional techniques and devices that activate the siphon action require that any device or method has an opening / closing device in the water absorption part and the drainage part of the water supply pipe. After filling the entire water pipe by pouring water from the highest part of the pipe, both opening and closing devices were opened. According to this conventional device and method, it is necessary to open and close the opening and closing devices of the water inlet and the drain. Since the water intake port is in the water, it is extremely dangerous and difficult, and the opening and closing of the discharge port is also very dangerous because it is performed manually by descending the slope. However, since the siphon activation method of the present invention is such that the water inlet in the high water level region is open and the discharge port on the low region side is always open, the water supply pipe is gradually filled with water as in the prior art. I can't. Therefore, the amount of water that fills the inside of the water supply pipe at once is pushed out by discharging the air in the water supply pipe from the discharge port while the water injected into the water injection part of the water injection junction member connected to the water supply pipe flows downstream. When the water injected into the water pipe is discharged from the outlet by shutting off the water injection from the water injection part when the water pipe is flowing in a full state, the water injection of the siphon water supply device The water in the reservoir 90 in the high water level region is sucked from the water inlet of the water pipe with the drawing action of the air in the upstream water pipe from the confluence member, and the absorbed water is drained from the downstream outlet. To activate the siphon. That is, the present invention pushes air in the downstream direction while maintaining the full water state in the entire cross section in the water pipe sequentially from the upstream side toward the low area side from the water injection part of the water pipe at the stage of pouring the water pipe. It is a method of starting the siphon action of pouring water. Thereby, by drawing the water in the high water area into the water supply pipe, the entire water supply pipe is finally filled with water and flows down, so that a complete siphon action can be activated. As a result, the siphon water feeding device and the water feeding method, which are siphon activation methods that can omit the opening and closing operation of the water suction port and the discharge port, which are dangerous operations due to human power, are provided. In addition, it can also be used as a device that siphons earth and sand together with water and simultaneously discharges sediments such as lake bottoms by siphon action. By using these sand discharging methods, theoretically, a water head difference of 10 m, a water pipe diameter of 200 mm, and a siphon sand discharging device with a diameter of 200 mm are ideal. As a device to prevent the phenomenon of coarsening of rivers and the disappearance of sandy beaches, it will be possible to move 40m ^{3 to} 60m ³ of earth and sand to the downstream side of the dam without using electricity or fuel. This energy should be used by all means.

  Embodiments of the siphon water feeding device and the water feeding method of the present invention will be described in detail based on the drawings. The embodiments and drawings described below exemplify a part of the embodiments of the present invention, and are not used for the purpose of limiting to these configurations. Some of the cross-sectional lines in the drawing are omitted.

(First embodiment)
A siphon watering device 100 according to the first embodiment is shown in FIG. Drawing 1 is a side view showing the outline of the composition of siphon water feeder 100 concerning a 1st embodiment. The siphon water supply device 100 according to the first embodiment mainly includes the water supply pipe 10, the water injection unit 11a, the water absorption unit 11b, and the water injection unit 11c that form the water injection unit 11c, and the amount of water supplied from the water injection unit 11a. A water injection opening / closing device 70 to be adjusted and a water feeder 40 for supplying water to the water supply pipe 10 are provided.

  As the water supply pipe 10, a pipe whose cross-sectional shape is not easily deformed can be used. If a soft material such as a so-called sunny hose is used and there is no means to prevent deformation, if the water feeding operation by pressure feeding is interrupted, the hose cross section is crushed by atmospheric pressure and the siphon action is difficult to start. Because. As an example of a pipe using a hard material, it is possible to use a pipe in which a plurality of pipe members made of a hard polyethylene pipe having an inner diameter of φ50 mm or more are connected. The water supply pipe 10 is not always provided with an opening / closing member at the discharge port 12 on the low area side, and is always in an open state. Since the opening / closing member is not provided, the opening / closing operation can be omitted, and the danger of the worker due to approaching the opening / closing operation can be avoided. Further, as shown in FIG. 2, the end of the discharge port 12 of the water supply pipe 10 is obliquely lifted and disposed so as to be positioned at a height equal to or higher than the diameter of the water supply pipe 10. Intrusion of air from 12 can be prevented. That is, when the discharge port 12 is formed low, the water pressure due to the difference in water level is reduced when the water level on the suction side (upstream side) is lowered, so the momentum of water discharged from the discharge port 12 is reduced. Thereby, it changes from the water discharge phenomenon in the state which filled the water flow cross section of the discharge port 12 of the water supply pipe 10, and as shown to FIG. There is a possibility that the siphon action will be lost by gradually entering from the upper side of the discharge port 12. However, as shown in FIG. 3A, the air does not enter below the air inflow limit line G by lifting up to a height equal to or higher than the diameter of the discharge port 12. Thereby, when the water level of the storage part 90 in a high water level area falls and it is going to stop drainage temporarily, water closes the apparatus which opens and closes the pipe cross section provided in the middle of the water supply pipe 10, and water is supplied to the water supply pipe 10 Therefore, the siphon can be restarted simply by opening the opening / closing device in order to restart the siphon action.

  Moreover, even if the material itself is made of a soft material, the water supply pipe 10 can be used with a configuration in which the cross-sectional shape does not easily deform. For example, as shown in FIG. 4, there is a water supply pipe 10 a in which a coil-like expansion / contraction spring-like member 15 a is inserted inside a hose-like soft cylindrical member 15. The elastic spring-like member 15a is an elastic spring that can maintain the inner cross-sectional shape, and is formed of an elastic spring having a diameter slightly smaller than the inner diameter of the cylindrical member. The telescopic spring-like member 15a is a cylindrical member formed in a spherical shape, a football shape or a conical shape (FIG. 4 shows a conical shape) for expanding the internal cross section of the tubular member 15 at the tip. A pushing-out part 15b is provided. As shown in FIG. 4B, the tubular member flaring portion 15b is pushed in the downstream direction by water injected from the rear of the telescopic spring-like member 15a. The space | interval of 15a will be expanded and the cross-sectional shape inside the cylindrical member 15 will be maintained. The cylindrical member flaring portion 15b is separated from the expansion spring-like member 15a at a point where the expansion spring-like member 15a is appropriately extended. Furthermore, when using the long water supply pipe 10, as shown to FIG. 4C, the same 2nd expansion-contraction spring-like member 15c is previously attached downstream, and the cylindrical member expansion part 15b is a 2nd expansion-contraction spring-like member. 15c passes through the inside of 15c and reaches the rear end of the second tubular member flaring portion 15d attached to the tip of the second elastic spring-like member 15c, and the first tubular member flaring portion 15b and the second tubular shape. It is possible to hold the tubular member 15 in an expanded state by connecting the member expanding portion 15d and pushing the tubular member 15 again with water pressure from the upstream side. By repeating the necessary extension, the inner cross-sectional shape of the flexible cylindrical member 15 is maintained, and the inner cross-section of the water supply pipe 10 is prevented from being crushed by atmospheric pressure. According to this, since the soft hose-like cylindrical member 15 can be wound and transported or stored, space saving can be achieved.

  On the other hand, as shown in FIG. 5, the water inlet 13 arranged in the high-water-level-side storage section 90 is provided with a certain mesh-like dust suction prevention member 80 so as to cover the periphery of the water inlet 13. ing. Thereby, dust larger than the mesh of the dust suction preventing member 80 is prevented from being sucked into the water supply pipe 10. The mesh size may be the same as or slightly smaller than the opening of the water inlet 13. By setting this size, dust larger than the water suction port 13 is blocked by the mesh of the dust suction prevention member 80, and finer dust than the water suction port 13 is sucked into the water suction port 13 and then passes through the water supply pipe 10. As a result, the dust can be prevented from being clogged in the mesh of the dust suction preventing member 80 by this structure, so that the operation of removing the clogged dust can be omitted. A float 81 is attached to the water supply pipe 10 near the water inlet 13. The float 81 is wound around the water supply pipe 10 and has a function of protecting the water supply pipe 10 from an impact when the suspended matter 83 collides with the water supply pipe 10. Moreover, it has the function to adjust the water depth position of the water intake port 13 by adjusting the position of the float 81. As a result, the water suction port 13 can be submerged to an optimum depth while avoiding suspended matter on the water surface, so that only water can be sucked. Further, by installing the water inlet 13 at a height that reaches the bottom of the lake, the sediment deposited on the bottom of the lake can be sucked and discharged from the outlet 12 on the downstream side of the low area.

  As shown in FIG. 6, the water supply pipe 10 includes a water injection part 11 a for injecting water, a water absorption part 11 b provided on the water absorption side, and a water supply part 11 c for supplying these waters. The member 11 is connected. Basically, the water injection / merging member 11 may be formed at the highest point of the water supply pipe 10 or at a lower region side than the highest point. As a result, when the water storage tank 40 is used as the water supply device 40, the capacity of the water storage tank 40 is small compared with the case where the water storage tank 40 is provided upstream from the highest point, and temporary structures such as foundation work and scaffolding work are necessary. Disappear. In addition, when using a drainage pump vehicle or a submersible pump that operates using electricity or fuel as power as the water feeder, there is no need for a temporary structure even at the upstream side of the highest point at the place where the water injection / merging member is installed. Further, the water injection section 11a has a length of the water supply pipe 10 that is filled when water is injected from the water injection section 11a (the length of the water supply pipe 10 between A in FIG. 1). From the distance (the length of the water supply pipe 10 between B in the case of FIG. 1) from the water surface position 91 of the reservoir 90 on the high water level side to the position of the water supply pipe 10 at the same height on the low area side Also installed to be longer. When the supply of water from the water injection section 11a is blocked by the water injection opening / closing device 70 or the like in the water supply pipe 10 on the downstream side that is full of water, the water in the water supply pipe 10 continues to flow down to the downstream side as it is. . When the water flows down, the water in the water supply pipe 10 on the upstream side of the water injection / merging member 11 is drawn downstream so that the water in the reservoir 90 in the high water level region is drawn from the water inlet 13, and the drawn water is in the low area. By discharging from the discharge port 12, the inside of the water supply pipe 10 becomes full, and the water in the reservoir 90 in the high water level region is connected to the discharge port 12 in the low region in the water supply pipe 10 to activate the siphon. More preferably, in consideration of a loss when water is supplied, the length of the water supply pipe 10 that is full of water (the length of the water supply pipe 10 between A in the case of FIG. 1) is the high water level side of the water supply pipe 10. Longer than twice the distance from the water surface position 91 of the reservoir 90 to the position of the water supply pipe 10 at the same height on the low area side (the length of the water supply pipe 10 between B in FIG. 1) It is good to provide.

  Further, as shown in FIG. 6, the water injection and merging member 11 connected to the water supply pipe 10 is connected to a part of the water supply pipe 10 that operates the siphon, and is formed in a substantially Y shape. The end portions of the water injection part 11a, the water absorption part 11b and the water supply part 11c are provided with flanges and can be connected to the water supply device 40 and the water supply pipe 10. A flow direction check valve 18 extending in the water supply direction is provided inside the junction of the water injection part 11a and the water absorption part 11b. The water injection part 11 a side and the water absorption part 11 b side merge at an acute angle to form a water supply part 11 c with respect to the direction of the discharge port 12. The structure in which the angle of change from the water injection part 11a and the water absorption part 11b to the water supply part 11c is an obtuse angle, so that the angle of water flow during water injection and water absorption does not change greatly, so it is possible to reduce the decrease in resistance and flow velocity. The structure of the flow direction check valve 18 provided at the point prevents the water from flowing into the water absorption part 11b when water is injected from the water injection part 11a, and allows the flow from the water absorption part 11b to flow into the water injection part 11a. There is an effect to prevent. In particular, when the extension of the water supply pipe 10 to the downstream side is long, or when the water supply pipe 10 is bent and resistance to the flow is generated, water tends to flow to another route along with the phenomenon that the flow stagnates due to the resistance. Therefore, this can be prevented and water can flow in the direction of the discharge port 12 on the downstream side. A water injection opening / closing device 70 may be provided at the end of the water injection portion 11a, or a water injection opening / closing device 70 having a separate opening / closing function may be provided. The water flow from the water injection section 11a can be changed to the flow from the water absorption section 11b also by closing the water injection opening / closing device 70. Furthermore, instead of the water injection opening / closing device 70 disposed between the water feeder 40 and the water injection unit 11a, as shown in FIG. 7, a water injection connection device 20 provided with connection members 22 at both ends of a flexible hose such as a sunny hose is provided. It can also be arranged. When a flexible hose is used, when the water supply operation of the water supply device 40 is stopped, the flexible hose is caused by the pressure difference between the water pressure inside the water injection coupling device 20 composed of a flexible hose such as a sunny hose and the external air pressure. The cross section is deflated and can be closed. For this reason, it is possible to omit opening and closing operations by human power. Furthermore, the flow of air and water can be more reliably blocked by using the water injection coupling device holding tool 21 that can sandwich the flexible hose in the closed state in a sealed state. In this way, it is possible to prevent the siphon action from being stopped due to air being sucked into the water supply pipe 10 from the water injection part 11a after the water injection operation is interrupted, so that the water supply device 40 can be removed from the water injection connection device 20. At this time, as a mechanism for attaching the water injection connecting device 20, as shown in FIG. 7C, a connection having through holes 25 on both end surfaces of the water passing member of the water injection connecting device 20 constituted by a flexible hose member such as a sunny hose. The member 22 is formed, and the same connecting member 22 is provided on the end surfaces of the water injection part 11a, the water feeder 40, the water pipe, etc., and the connecting member 22 is overlapped with the positions of the through holes 25 and bolts and nuts. It is also possible to use a fixing method. Moreover, after inserting the insertion part 26 which is a part of the connection clip 23 which can pinch | interpose the two connection members 22 in the state which inserted the insertion part which is a part of the connection clip 23 in the through-hole 25, after connecting The water injection connecting device 20 can be easily connected to the water injection portion 11a and the like by inserting the connecting member 22 that is overlapped by hitting the pinching portion 27 of the clip 23 with a hammer or the like.

  Moreover, as another water injection joining member 11, it comprises a substantially T shape as shown in FIG. 8, and the water injected into the branch part of the flow of the water injection joining member 11 which has the water injection part 11a is a high water level area. The water supply direction switching device 19 that can switch the water supply to the side or the low-area side may be provided. The water supply direction switching device 19 can switch the position of the water supply direction switching valve 19a to the α side or β side by moving the water supply direction switching lever 19b, and can switch the water supply direction. For example, when the water supply direction switching valve 19a is arranged at the position α, the water injected from the water injection section 11a is supplied in the direction α ′, and when the water supply direction switching valve 19a is arranged at the position β, the water injection section 11a. The water poured from the water will be sent in the direction of β ′. Furthermore, when it arrange | positions in the position of (gamma), it is the state in which the water supply direction switching valve 19a is accommodated, water can be supplied to both sides, or the fixed range in the water supply pipe 10 is a full water state. In such a case, the water supply operation can be continued only in one direction from the α side to the β side or from the β side to the α side by blocking the water injection from the water injection unit 11a.

  Further, as shown in FIG. 1, a plurality of air valves 14 may be provided on the water supply pipe 10 at a downstream side of the water injection / merging member 11 at intervals. The maximum amount of drainage due to siphoning is determined by piping to the optimum head differential according to the height of each head. The head changes at the same time as the water level of the reservoir 90 changes. In order to secure the maximum drainage amount according to the fluctuating water head difference, it is necessary to move the discharge port 12 of the water pipe 10 so as to obtain an optimum water head difference, or to change the extension of the water pipe 10 and to perform new piping work. Become. However, by providing the air valve 14 with an interval in the water supply pipe 10, the water supply pipe 10 can be changed to an optimum water head difference in order to ensure the maximum amount of drainage determined by the height of each head. That is, when the water level of the reservoir 90 rises and the head becomes smaller, the air valve 14 is closed sequentially from the upper part toward the lower part to open the air valve 14 having a height that is the optimum water head difference or less. Even if new piping work is not performed, it is possible to obtain an optimum water head difference. Also, when the water level is lowered and the head is increased, the optimum head difference becomes smaller. Therefore, the closed air valve 14 is opened from the bottom up to the air valve 14 having the height corresponding to the optimum head difference, and new piping work is performed. Even if it does not do, it can be set as the optimum water head difference. The air valve 14 is an air valve having such a size that the size of the opening of the air valve 14 can suck in enough air to release the water pipe from siphoning (for example, a size of 1/4 or more of the diameter of the water pipe 10). If it exists, it can be set as the state similar to the discharge port open | released to air | atmosphere by making all the air valves 14 into the closed state, and opening only the air valve of the position used as the optimal water head difference. Thereby, even if the water level of the storage part 90 is changed, the water head difference can be changed to the optimum water head difference by correspondingly opening and closing the air valve 14 only. Specifically, as shown in FIG. 9, in the case of the head A, the optimum head difference is a, in the case of the head B, the optimum head difference is b, and in the case of the head C, the optimum head difference is The optimum head difference varies depending on the height of the head that accompanies the fluctuation of the water level in the reservoir, but the optimum head is provided by providing a plurality of air valves 14 in the water supply pipe 10. The difference can be easily selected.

  The water feeder 40 can inject water from the water injection section 11a of the water injection confluence member 11 into the water supply pipe 10 on the low region side, and can fill the water supply pipe 10 with water while the water is discharged from the discharge port 12. It is necessary to be a proper device. The water supply device 40 may be, for example, a pumping device for a vehicle having a water supply / drainage capability such as a drainage pump vehicle of a disaster countermeasure vehicle owned by a country or a local government, a fire engine, or a submersible pump. When road conditions and topographical conditions that allow entry to a site where a disaster such as a sediment dam has occurred are satisfied, the water injection and merging member 11 directly utilizes a large-scale water supply and drainage function such as a drainage pump car that operates by power. It can connect with the water injection part 11a, pour water into the water supply pipe 10, and can start a siphon action.

  When the water feeder 40 having such a large amount of water supply / drainage capacity cannot be carried in, a water storage tank 40 may be used as the water feeder 40 as shown in FIG. The water supply device 40 using the water storage tank pumps the water injection into the water supply pipe 10 using the water pressure that is the weight of the water itself supplied into the water storage tank 40, and is at least lower than the water injection confluence member 11. It is necessary to have a water volume and a height that can fill the inside of the water supply pipe 10 on the side, and a size that can provide a water force that can maintain a full water state. Here, touching on the height of the water storage tank 40, when there is a point where the terrain downstream from the water injection / merging member 11 is higher than the water injection / merging member 11, that is, upstream from the highest point in the extension between all the laying pipes 10. In the case where the water storage tank 40 is joined to the water injection / merging member 11 and the siphon water supply device 100 is laid, the water storage tank 40 and the water injection / merging member 11 are installed again at a position higher than the highest point, or the volume of the water storage tank 40 is increased. However, it is necessary to provide a volume higher than the height of the highest point on the downstream side and a volume sufficient to fill the water supply pipe 10 downstream from the water injection / merging member 11. In addition, if the water storage tank 40 is configured to be a large-capacity water storage tank 40 by combining a plurality of water storage tank assembly members 41, the water storage tank 40 can be easily carried into the site. Specifically, the water tank assembly member 41 is a foldable free material that uses a flexible material and can withstand a hydraulic load when water is stored, or a combination of a plurality of water tank assembly members 41 to provide a large capacity. It is preferable to use what can be used as a tank. For example, if it is a steel metal foam (formwork material) when constructing a concrete structure, it can be divided into a range that can be transported manually, and the scale of the water supply pipe 10 in the disaster location is changed each time. It is effective because it is highly convenient and can be freely assembled to the required size of the water storage tank 40. In addition, since the structure of the joint of the metal foam for formwork is not sealed in order to discharge air and excess moisture when placing concrete, it is necessary to use a blue sheet or the like to make the assembled water storage tank watertight. When the inner surface of the water storage tank is covered with a water shielding member, the water tightness is further improved.

  A part of the water tank assembly water passage member 60A is provided with a water passage opening 60B, and is provided with a water flow amount adjusting on / off valve 60 to supply water to the water injection / merging member 11, The stop and the amount of water may be adjustable. For example, as shown in FIG. 10, the water flow amount adjusting on-off valve 60 includes a water flow amount adjusting on-off valve 60 when the water storage tank 40 serving as a water feeder is connected to the water injection portion 11 a of the water injection merging member 11. By using the water tank assembly water passing member 60A together with the water tank assembly member 41 such as metal foam for the assembly of the water storage tank 40, the water storage tank 40 having an opening / closing portion close to the function of the water injection opening / closing device 70 can be assembled. . The upper and lower ends of the water flow adjusting valve 60 are fixed by a hinge 62 so that a pulley 63 is formed below the water flow adjusting open / close valve 60. For example, the pulley 63 is provided with a cable 64 fixed on one side. By pulling the cable 64 on the opposite side of the fixed side, the pulley 63 functions as a moving pulley and has a half force. The opening / closing valve 60 for adjusting the water flow rate can be opened. A plurality of bolt fixing holes 65 are formed around the water flow amount adjusting on / off valve 60. The bolt fixing holes 65 are provided in front of the flange of the water injection part 11a or the water injection part 11a. Can be fixed to the flange of the water injection switching device 70 having a high barrier property. The water storage tank 40 is assembled with the water storage tank assembly member 41 such as a general-purpose metal foam by providing the water supply opening 60B for the water storage tank assembly and the opening / closing valve 60 for adjusting the water flow rate. In this case, the water storage tank 40 can be easily provided with the water flow opening 60B and the water flow adjustment valve 60 by using the water tank assembly water flow member 60A in combination.

  As another embodiment of the water flow amount adjusting on / off valve 60, as shown in FIG. 11, the fixing portion 68 of the water flow amount adjusting on / off valve 60 provided in the water tank assembly water passing member 60A has a water flow opening. It is each provided in the circumference | surroundings which the part 60B opposes, and the outer side of each water flow amount adjustment on-off valve 60 is being fixed so that rotation is possible. As a result, when the water flow adjusting valve 60 is closed, water pressure is applied to both of the two fixed portions as a boundary by the flow of the water opening 60B. When opening the valve, the water flow rate adjusting on / off valve 60 is rotatably fixed at two locations on the outer periphery, so the cable 64 is pulled against one side in the opposite direction to the flow direction ( (a direction), the other end of the water flow adjusting valve 60 is pushed by the flow water pressure and the water flow adjusting valve 60 rotates in the opening direction, so that the cable 64 is loosened (b direction). Also good.

  Moreover, as shown in FIG. 12, you may provide the apparatus which has an opening / closing function separately as the water injection opening / closing apparatus 70 between the water injection part 11a of the water injection confluence | merging member 11, and the water feeder machine 40. As shown in FIG. The water injection opening / closing device 70 shown in FIG. 12 is formed in a cylindrical shape as a whole, and has connecting members 22 formed of flanges to which the water injection part 11a and the water feeder 40 can be attached, respectively. Further, a water flow amount adjusting valve 71 connected to an outer adjustment lever 76 is provided inside the cylinder, and the amount of water from the water feeder 40 can be adjusted by the adjustment lever 76. The water flow amount adjusting valve 71 may be flat and formed in a hemispherical shape so that the adjusting lever 76 can be easily operated by reducing the water pressure. The water flow amount adjusting valve 71 connected to the adjusting lever 76 is structured to be rotatable with a fixed hinge. However, since the inflow of air is the most important matter for siphon action, this hinge is used. The part is provided with an air blocking member 78 for preventing inflow of air.

  About the siphon water feeder 100 comprised as mentioned above, an installation method and a usage method are demonstrated with reference to FIG. First, the water intake port 13 is disposed in the reservoir 90 in the high water level region, and the water supply pipe 10 is installed so that the discharge port 12 is disposed in the low region. And the water injection confluence | merging member 11 which has the water injection part 11a in the whole extension of the water supply pipe 10 is arrange | positioned. Then, the water feeder 40 is connected to this water injection part 11a. In FIG. 1, a water storage tank 40 is used as the water feeder 40. The water storage tank 40 is provided with a water flow amount adjusting on-off valve 60 (see FIG. 10) for adjusting the amount of water supplied to the water injection section 11a. Moreover, when the water injection part 11a discharges water, it is necessary to fill the downstream water supply pipe 10 with water at a stretch, so that the water passage section of the water injection part 11a is the same as the diameter of the water supply pipe 10, or It is desirable to have the above size.

  Then, the water is stored in the water storage tank 40 using the water in the storage unit 90 with the water flow amount adjusting on / off valve 60 closed. When the water is stored in the water storage tank 40, if the siphon device 200 that can be started up by using a water tank that is small enough to start up by pouring 5 to 10 times of bucket water, Water can be stored in the water storage tank 40 without using the water. Then, it is confirmed that the water storage tank 40 has stored more than the amount of water that can fill the water supply pipe 10 downstream of the water injection and joining member 11 of the water supply pipe 10 and fills the water storage tank 40 with water. To stop. The siphon water supply device 100 according to the first embodiment is directly connected to the water supply pipe 10 if the function of the pump such as a pumping device has a water supply amount enough to push out the air in the water supply pipe 10 at once. The method of pouring water into the water injection part 11a of the water injection / merging member 11 can be used. In the case of the method of use described here, a water storage tank is used as a water feeder, so that water is temporarily stored in the water storage tank 40 and then the water pressure accumulated in the water storage tank is used to inject the water into the water supply pipe 10 through the water injection / merging member 11. Therefore, even if it is another pumping machine smaller than the diameter of the water pipe 10, water can be stored in the water storage tank 40 and used as a water feeding machine. Therefore, when using a pumping device such as a small submersible pump, a small generator can be used, which makes it easier to carry by manpower and makes the pumping device operate compared to using a large-capacity generator. Less power is required.

  After the water storage operation is completed in the water storage tank 40, the water flow amount adjusting on-off valve 60 and the water injection on-off device 70 are fully opened. Then, the water in the water storage tank 40 is vigorously poured into the downstream side of the water injection / merging member 11 of the water supply pipe 10 via the water injection / merging member 11. In other words, it flows down to the low area. If this state is continued for a while, at least the water supply pipe 10 on the lower area side than the water injection and confluence member 11 is still in a state where the water supply pipe 10 flows while water is discharged from the discharge port 12 as shown in FIG. 13A. The full water state is maintained (shaded portion in the water supply pipe 10). Initially, water ejected from the discharge port 12 is mixed with air and white water is ejected, but it can be confirmed that the water is changed to transparent water when the inside of the water supply pipe 10 becomes full. If it will be in this state, the water injection switch 70 provided in the water injection confluence | merging member 11 will be closed, and the water injection from the water storage tank 40 to the water supply pipe 10 will be stopped. Even if the water injection from the water storage tank 40 is stopped, the water is continuously drawn and discharged from the discharge port 12 that is always open in the low area on the downstream side. The action of the state water flowing downstream works. By the action of flowing downstream, as shown in FIG. 13B, the water in the reservoir 90 is sucked into the water supply pipe 10 from the water intake port 13 in the high water level area together with the phenomenon that the air in the water supply pipe 10 is drawn downstream. It is. Then, when the drawn water passes through the position E of the water supply pipe 10 at the same height as the water surface of the reservoir 90, water automatically flows into the water supply pipe 10 as shown in FIG. 13C. The siphon action to start will start. When the air or the like in the water supply pipe 10 is completely discharged from the discharge port 12, the water supply pipe 10 between the water in the reservoir 90 in the high water level region and the discharge port of the water supply pipe 10 laid in the low region. The inside is connected in a full state, and the operating state of the siphon action is completely maintained.

  According to the siphon water feeding device 100 configured as described above, once preparation is completed and the water can be drained from a high water level to a low area by the siphon action, thereafter, by using natural energy without requiring electric power. The water of the storage unit 90 can continue to flow to a low area. For this reason, the fact that there is no need to carry in and supply fuel for power generation after that is a significant effect. As a result, the installation cost of the siphon water supply device, the water supply cost, and the maintenance of the water supply work can be greatly reduced. In addition, since it is not necessary for many workers to approach the vicinity of the discharge port to perform the opening / closing operation of the switchgear, secondary disasters such as workers can be prevented by monitoring from a safe place.

  Further, according to the siphon water supply device 100 according to the first embodiment, since the hard pipe whose inner cross-sectional shape is difficult to change is used, the water supply pipe 10 is crushed at the bent position, or inside the water supply pipe 10. Even when the amount of water decreases, the cross section of the water supply pipe 10 is not crushed by the atmospheric pressure, and the possibility that the function of siphon action is reduced can be reduced.

  Furthermore, according to the siphon water supply device 100 according to the first embodiment, since a large device such as the water storage tank 40 can be disassembled for each member, it can be easily transported by manpower, and transport vehicles, heavy equipment, helicopters and the like enter. Even in areas where it is impossible, it can be transported manually.

  Furthermore, the siphon water supply device 100 according to the first embodiment does not inject water directly into the water supply pipe 10 from a pump such as a pumping device by using a water storage tank, and once uses a relatively small pumping device. Then, water is injected into the water supply pipe 10 with the water pressure of the water stored after the water is stored in the water storage tank 40, so that it is small without requiring a pumping machine using a large-capacity electricity as a driving source. It is also possible to store water in the water storage tank 40 using a small pump using another submersible pump or the like. Therefore, the electric power required for the pumping machine is less than the electric power required to operate the large capacity pumping machine, and a small generator can be used. In addition, as the shape of the water storage tank 40 used in this case, a vertically long shape is preferable so that the water pressure increases when water is supplied.

(Second Embodiment)
A siphon water feeding device 100 according to the second embodiment is shown in FIG. The siphon water supply device 100 according to the second embodiment is an example in the case of laying a multi-strip pipe, and is substantially the same as the first siphon water supply device 110 and the first embodiment. The second siphon water supply device 120 that does not have the water supply device 40 and the intake pull-in hose 50 that connects them are provided.

  The 1st siphon water supply apparatus 110 is between the highest point of the water supply pipe 10c of the 2nd siphon water supply apparatus 120, or the downstream from the highest point with respect to the water supply pipe 10 with respect to the siphon water supply apparatus 100 concerning 1st Embodiment. The difference is that the connecting intake pull-in hose 50 is attached so as to communicate. The intake hose 50 is provided with a first hose opening / closing member 51 that can be opened and closed with respect to the state of communication with the water pipe 10. The intake hose 50 preferably has a diameter smaller than the diameter of the water supply pipe 10. This is because if it is thicker than the water supply pipe 10, the force for drawing air or water in the intake hose 50 is weakened.

  On the other hand, in the second siphon water feeding device 120, a water feeding pipe 10 similar to that of the first embodiment is installed near the first siphon water feeding device 110 between the reservoir 90 in the high water level region and the low region. An end portion on the opposite side of the suction pipe hose 50 is connected to the highest point of the water supply pipe 10 or downstream from the highest point. Similarly, the second hose can be opened and closed with the communication state with the inside of the water supply pipe 10c. An opening / closing member 52 is provided. Further, in the water supply pipe 10c of the second siphon water supply device 120, the inside of the water supply pipe 10c is opened and closed at a position lower than the water level of the high-water-level storage section 90 on the downstream side of the connection portion with the intake air drawing hose 50. An in-pipe open / close valve 16 is provided to open and close the cross section in the water supply pipe 10.

  The siphon watering device 100 according to the second embodiment manufactured as described above is activated as follows. First, the siphon of the first siphon water feeder 110 is activated. Since the siphon activation method of the first siphon water feeding device 110 is the same as that of the first embodiment, the description thereof is omitted. The second siphon water supply device 120 connects the intake hose 50 to the first hose opening / closing member 51 of the first siphon water supply device 110 in a state where the pipe opening / closing valve 16 is closed. From this state, the first hose opening / closing member 51 and the second hose opening / closing member 52 are opened. Either order may be used. Thereby, the air of the suction hose 50 is drawn into the first device 110 by the siphon action of the first siphon water feeding device 110. As a result of this drawing, the air in the water pipe 10c of the second siphon water feeder 120 decreases, so that the water in the reservoir 90 in the high water level region is sucked into the water pipe 10c of the second siphon water feeder 120. When the sucked-in water fills the space between the water inlet 13 laid in the high-water-level storage section 90 of the second siphon water feeder 120 and the pipe opening / closing valve 16 that opens and closes the water pipe 10c, the pipe opens and closes. When the device is opened, the water in the water supply pipe 10 flows down to the discharge port 12 on the low area side by gravity, and the air in the water supply pipe 10 downstream from the pipe open / close valve 16 is exhausted from the discharge port. When the inside of the water supply pipe 10 between the water in the storage unit 90 and the discharge port of the water supply pipe 10 laid in a low area is connected in a full state, the siphon action is completely activated and the operating state is maintained. Thus, the second siphon water feeder 120 can activate the siphon without using any power. Using the siphon flow of the first device or the second siphon water supply device activated in this way, the intake pipe hose 50 of the water supply pipe 10c of the third and subsequent siphon water supply devices is located downstream of the highest point or the highest point. By connecting the end portions and repeating the same work, a multi-strip piping work by siphon can be operated.

(Third embodiment)
A siphon water feeding device 100 according to the third embodiment is shown in FIG. The 1st siphon watering apparatus 100 concerning 3rd Embodiment is a further another example in the case of laying multi-strip piping, and the 1st siphon watering apparatus 110 substantially the same as 1st Embodiment is a water feeder machine. A water injection hose 53 is provided that connects between the water injection opening and closing device 70 provided in the water injection confluence member 11 of one or more second siphon water supply devices. One or more second siphon water feeding devices 120 differ from the first embodiment in that they do not have a water feeder.

The siphon water feeding device 100 according to the third embodiment manufactured as described above is activated as follows. First, when the first siphon water feeding device 110 (1) is activated and the siphon action is activated, the opening / closing device A is closed and the water injection opening / closing device 70a connected to the water storage tank 40 is opened. Flows into the storage tank 40, which is a water feeder, thereby filling the storage tank 40 with water. Next, when the water storage tank 40 is full, when the water flow adjustment valve 60 is opened, water flows to the water injection hose 53. Further, the water flowing through the water injection hose 53 is injected as priming water through the water injection opening / closing device 70b provided in the water injection part 11a of the water injection / merging member 11 connected to the water supply pipe 10d of the second and subsequent siphon water supply devices (2). Is done. When the water supply pipe 10d becomes full, the siphon water supply device (2) of the second siphon water supply device 120 is started by closing the water injection opening / closing device 70b provided in the water injection part 11a of the water injection / merging member 11, and then the water injection / merging member 11 The water injection hose tube tip 53a of the water injection hose 53 is removed from the water injection opening / closing device 70b provided in the water injection part 11a. Further, similarly, the water injection hose tube tip 53a of the water injection hose 53 is joined to the water injection opening / closing device 70c provided in the water injection part 11a of the water injection confluence member 11 of the third and subsequent siphon water supply devices (3) and the same operation is performed. The siphon of the siphon water feeder (3) is activated. By sequentially repeating such operations to the third and subsequent siphon water supply devices 120, siphon drainage work by multi-strip piping can be performed. In this embodiment, an example in which a water storage tank 40 is used as a water supply device is described. However, if the water supply device 40 has a water absorption and water supply function such as a drainage pump vehicle and a submersible pump, the discharge port of the water supply pipe is the water injection hose. Since it becomes the tube tip 53a, it is connected to the water injection opening / closing device 70a of the first siphon water supply device 110 for water injection, and when the water supply pipe 10 becomes full, the water injection opening / closing device 70a is closed and the siphon is supplied to the siphon water supply device 110 (1). After the operation, the water injection work is performed in the same manner as the first siphon water supply device described above by joining the water injection opening / closing device 70b of the water injection part 11a provided in the water injection / merging member 11 of the second and subsequent siphon water supply devices 120. After the water supply pipe 10d is filled with water, the water injection opening / closing device 70b provided in the water injection section 11a is closed and the siphon water supply device (2) The siphon water supply work by multi-strip piping becomes possible by repeatedly performing the work to start the action. In addition, although expressed as the water injection opening / closing device 70 provided in the water injection portion 11a of the water injection junction member 11, the water injection portion 11a and the water injection opening / closing device 70 may be configured by connecting separate structures, or integrated. It may be the structure of.

  In addition, in the method of the multi-strip piping in this 3rd Embodiment, although the water injection confluence | merging member 11 provided in the 2nd siphon water feeder represents substantially T shape, it will merge if it is substantially Y shape. There is an effect to reduce the resistance of the water flow.

(Fourth embodiment)
A siphon water feeding device 100 according to the fourth embodiment is shown in FIG. The siphon water supply device 100 according to the fourth embodiment is provided with a flexible water supply hose 24 that is foldable or foldable connected to a downstream end portion (discharge portion) of the rigid water supply pipe 10. The discharge port of the flexible water supply hose 24 is opened without an opening / closing device, like the discharge port 12 of the water supply pipe 10. The connection position of the water supply pipe 10 and the flexible water supply hose 24 is provided on the lower region side than the reference water head difference that can secure the maximum drainage amount, or is the same as or lower than the height of the water surface of the reservoir 90 in the high water level region. It is good to be connected downstream. This is because the siphon action can be maintained by disposing at this position. Flexible water supply by discharging the air in the water supply pipe 10 from the water supply pipe 10 by using a vacuum pump from the water injection opening / closing device 70 provided in the water injection part 11a of the water injection confluence member 11 connected to the highest point of the water supply pipe 10 The hose 24 is closed and hermetically closed as the air pressure in the water supply pipe 10 is reduced (FIG. 16A), and at the same time, the pressure reduction phenomenon sucks the water in the reservoir 90 in the high water level region into the water supply pipe 10. Furthermore, the water sucked by continuing to discharge air passes through the highest point of the water supply pipe 10 and flows down to the downstream side of the water supply pipe 10, and water begins to accumulate from the place where the flexible water supply hose 24 is closed and sealed (FIG. 16B). ). Thereafter, the closed portion of the flexible water supply hose 24 is gradually lowered due to the weight of the water accumulated up to the highest point of the water supply pipe 10 and starts to move (FIG. 16C). Furthermore, when the closed sealing portion of the flexible hose is pushed out and started to flow down, it can flow down with the air remaining in the downstream water supply pipe from the highest point of the water supply pipe 10 to activate the siphon action (FIG. 16D). ). Even in the structure of the drainage device, the flexible water supply hose 24 is not provided with an opening / closing device anywhere, so the work procedure does not include the operation of opening / closing the opening / closing device and can be omitted. The size of the water injection opening / closing device 70 when this vacuum pump is used does not need to be large enough to inject water all at once and activate the siphon action, and depending on the function of the vacuum pump, only the air is gradually discharged. Since the size is sufficient, the switchgear is also sized accordingly. For example, if there is a Φ10 mm intake hole and the structure of the switchgear associated therewith, it can function.

The sedimentary soil agitated in water is sucked together with water from the water inlet 13 and drained to a low area. Further, a cover 35 is provided on the upper portion and both side portions of the screw 31 so that the flow of rotating the screw 31 does not flow into the water inlet 13 from the rear of the screw 31. With this structure, the lower part of the screw becomes sedimentary soil, so the periphery of the screw 31 is covered with the screw cover 35 and the sedimentary soil surface, and the flow flows from the front surface of the screw 31, so that the flow is effective for rotating the screw 31. Become.

(Sixth embodiment)
The water inlet of the siphon water feeder 100 according to the sixth embodiment is shown in FIG. 18A is a schematic front view of the water inlet 13 of the siphon water feeder 100 of the sixth embodiment, FIG. 18B is a schematic plan view of the water inlet 13 of the siphon water feeder 100 of the sixth embodiment, and FIG. 18C is a siphon water feeder. 4 is a schematic side view of a water inlet 13 of the device 100.

A screw cover 35 is provided so that the flow of rotating the screw does not flow into the water inlet 13 from the rear of the screw 31. With this structure, the lower part of the screw becomes sedimentary soil, so the periphery of the screw 31 is covered with the screw cover 35 and the sedimentary soil surface, and the flow flows from the front surface of the screw 31, so that the flow is effective for rotating the screw 31. Become.

(Seventh embodiment)
The water inlet 13 of the siphon water feeder 100 according to the seventh embodiment is shown in FIG. 19A is a schematic front view of the water inlet 13 of the siphon water feeder 100 of the seventh embodiment, FIG. 19B is a schematic plan view of the water inlet of the siphon water feeder 100 of the seventh embodiment, and FIG. 19C is a siphon water feeder. It is a side surface schematic diagram of 100 water intake ports 13. The siphon water feeding device 100 according to the seventh embodiment relates to the form of the water inlet 13 of the water feeding pipe 10 disposed in the storage unit 90. In the siphon water feeding device 100 according to the seventh embodiment, two water inlets 13 arranged in the storage unit 90 are arranged, and the functions of the driving water inlet 13a and the water inlet 13b corresponding to the water inlet 13 respectively. Have. A screw 31 is attached to the drive water inlet 13a. The screw 31 is rotated by water absorbed by the driving water inlet 13a. By the rotation of the screw 31, the sediment at the bottom of the lake and the river is agitated in water. The sedimentary soil that has been agitated and floated in the water is sucked together with water from the water intake port 13b and drained together with water to a low area. According to this, even if the work of stirring the sedimentary soil underwater with a stirrer that uses electricity conventionally is performed without using electricity by changing the energy of the water absorbed from the drive water intake port 13a to the rotational energy of the screw 31. Stirring can be performed. According to this, since the water intake port 13b for absorbing sedimentary soil and the drive water intake port 13a for rotating the screw 31 are separated, there is a probability that the sedimented soil that is agitated in the water is absorbed while colliding with the screw 31. Since it decreases, the effect of preventing damage to the screw 31 can be exhibited. As a method of providing two water inlets 13, there are a method in which two water pipes 10 are provided, and a method in which two water inlets are provided but merged into one on the downstream side of the water inlet and configured as one water pipe 10. is there.

With the structure, the lower part of the screw becomes sedimentary soil, and the periphery of the screw 31 is covered with the screw cover 35 and the water intake port 13b, so that the flow flows from the front surface of the screw 31. Therefore, the flow is effective for rotating the screw 31. It becomes.

The siphon water feeding device 100 according to the eighth embodiment relates to the form of the water inlet 13 of the water feeding pipe 10 disposed in the storage unit 90. In the siphon water supply device 100 according to the eighth embodiment, a plurality of water intake ports 13 of the water supply pipe 10 arranged in the storage unit 90 are arranged, and the drive water intake port 13a and the water intake water intake port 13b are respectively provided corresponding to the water intake ports. Have. A drive screw 34 is attached to the drive water inlet 13a. The drive screw 34 is rotated by water absorbed by the drive water inlet 13a. On the other hand, the water suction port 13b is provided at a position away from the drive water suction port 13a. The water absorption inlet 13b is provided with a member for stirring sediment 32, and rotational energy obtained by the screw rotation of the drive screw 34 of the drive water intake 13a is transmitted to the interlocking member 33 and from the water absorption inlet 13b. The sediment mixing member 32 provided in the front can be operated. With this sedimentation earth stirring member 32, the sedimentation earth deposited on the bottom of a lake or river can be agitated in water and absorbed from the water absorption inlet 13b and absorbed and floated, and drained to a low area. According to this, since the water absorption of the sedimented soil that is stirred in water and floats is performed at the water intake port 13b, the suspended soil is absorbed from the drive water intake port 13a provided at a position away from the water intake port 13b. Since the probability is greatly reduced, the structure is greatly useful for preventing damage to the driving screw 34 rotating at the driving water inlet 13a. In this structure, the number of the water supply pipes 10 is the same as the number of the water inlets 13, and a plurality of water inlets 13 are provided, but the downstream side of the water inlets 13 is joined so that the number of the water supply pipes 10 is equal to or less than the number of water inlets. There is a way to configure it. In the case of the method of joining the water inlets downstream, it is desirable that the size of the cross-section of the water supply pipe 10 after joining is greater than the total cross section of the number of water inlets to join. Further, since the periphery of the drive screw 34 is in the pipe of the drive water inlet 13a, the flow flows from the front surface of the drive screw 34, so that the flow is effective for rotating the drive screw 34.

(Ninth embodiment)
A siphon watering device 100 according to the ninth embodiment is shown in FIG. FIG. 21 is a side sectional view of the water inlet 13 of the siphon water feeder 100 of the ninth embodiment. The siphon water supply device 100 according to the ninth embodiment relates to the form of the water inlet 13 of the water supply pipe 10 arranged in the storage unit. The siphon water supply device 100 according to the ninth embodiment is a water intake port member 13A for forming an oblique opening that is attached to the water intake port 13 of the water supply pipe 10 disposed in the storage unit 90, and the opening surface is formed to face obliquely upward. In addition, an open / close lid 13Ab is provided. In order to form the water inlet 13 diagonally, the end itself of the water supply pipe 13 may be cut diagonally, but when installing, it is difficult to adjust the angle of the opening surface, as shown in FIG. The water inlet member 13 </ b> A for forming an oblique opening may be separately prepared and attached to the water inlet 13 of the water supply pipe 10. By adopting such a configuration, the water inlet 13 can be reliably directed obliquely upward. In FIG. 21, the bolts and nuts are used for fixing, but the inner surface of the water supply pipe 10 and the cylindrical portion 13Aa of the oblique opening forming water inlet member 13A may be screwed and directly screwed together. Further, the oblique opening forming water inlet member 13A is provided with a float mounting portion 13Ae for connecting the float 81, and an oblique opening forming water inlet member 13A and an opening / closing lid 13Ab rotatably provided by a hinge. Have. Therefore, as shown in FIGS. 22A and 22B, when the water level rises, the float 81 also rises. Therefore, the opening / closing lid 13Ab can be lifted and opened, and when the water level descends to such an extent that the opening / closing lid 13b cannot be lifted, The lid 13Ab closes the water inlet 13 as shown in FIG. 22C. With this effect, when the water level falls below a certain level, the open / close lid closes due to its own weight, so that water absorption stops and water supply can be automatically stopped. In the temporary stop state of the water supply work, the water supply hose 10 is still in a full state, the movement of water is stopped, and the siphon action can be resumed at any time. Accordingly, when the water level on the water surface rises again, the float 81 rises accordingly, and the opening / closing lid 13Ab is pulled up to be in the open state, so that the water absorption operation is resumed, and accordingly the water in the water supply pipe moves downstream. Therefore, siphoning work starts automatically and water supply work is resumed.

By adopting such a configuration, when the tip of the water inlet 13 is thrown into the lake bottom or river bottom, even if the tip is thrown at a right angle or obliquely with respect to the bottom, the cover portion 13f contacts the bottom. In this state, since the water inlet 13 does not directly contact the bottom surface, the water inlet can be installed in an open state, and drool or pebbles are suddenly sucked from the water inlet 13 at the time of charging and the water inlet is clogged. It can be installed so as not to be in a state, and the water supply operation can be carried out while absorbing newly flowing water and earth and sand in this state. The cover portion 13f may be attached to the oblique opening forming water inlet member 13A attached to the water inlet 13 as shown in FIG. 23B. You may combine with 13 A of water inlet members for diagonal opening provided with opening-and-closing lid | cover 13Ab in 9th Embodiment.

(Eleventh embodiment)
FIG. 24 shows a connection auxiliary member 30 used for the water supply pipe 10 of the siphon water supply device according to the eleventh embodiment or the water injection part 11a of the water injection confluence member. It is a cylindrical member 30a which is a flexible member for covering and passing water through the connecting parts of the water supply pipes 10 having different diameters and which cannot be connected to each other or the water injection part 11a of the water injection / merging member and can withstand water pressure from the inside of 7 atm or more. Then, the water supply pipe 10 or the water injection part 11a of the water injection / merging member having different diameters is inserted from both side openings of the cylindrical member 30a made of a flexible and strong tensile material, and each of the water supply parts in a state where the connecting parts face each other. Water tightness may be improved by tightening with a tightening member 30b tightened together with the water supply pipe from the outside of the tubular member 30a at the neck of the pipe or the water injection part 11a.

An apparatus similar to that of the first embodiment was laid using a water supply pipe 10 having a total length of about 60 m having a suction hose with a diameter of 200 mm. The difference between the height at which the water pipe passes through the top (the part at the highest position of the water pipe) and the height of the water level of the reservoir is the maximum drainage amount. An experiment was conducted to see if it could be maintained. FIG. 25 shows the results of the confirmation of the height of the head that is the limit and the measurement experiment result of the top pressure. According to this, it is understood that the height of the maximum lift that can maintain the maximum amount of drainage is 7 m.

Next, at heads of 3 m, 5 m, and 7 m, the reference water head difference that can secure the maximum amount of drainage was measured with respect to the length of the entire length of the water supply pipe (pipe extension). The measurement results are shown in FIG. (Actually, there is a decimal point, but the numerical value is written in integers.) According to the measurement result, in order to secure the maximum drainage of about 7m ³ / min when the head is 7m, the pipe head difference is 60m. It can be seen that the optimal reference head difference is 10 m, 10 m, 12 m, 14 m, 15 m, and 15 m every time the extension increases by 20 m. In order to secure the maximum drainage of about 9m ³ / min when the head is 5m, the standard head difference is 12m at 60m, and 14m, 16m, 20m, 22m, 24m, 28m, 30m are required every time the extension increases by 20m. It can be seen that it is. In order to secure a maximum drainage of about 12 m ³ / min when the head difference is 3 m, the standard head difference is 20 m at 60 m. Thereafter, every time the extension increases by 20 m, 24 m, 30 m, 34 m, 38 m, 42 m, 44 m, 46 m It turns out that it is necessary. As a result, it is possible to secure the maximum amount of drainage by responding to the change in the head due to the fluctuation of the water level of the reservoir 90 in the high water level area by using the head difference of the siphon drainage device as the reference head difference corresponding to the head. .

  As shown in the above-described embodiment, it can be used as an apparatus for efficiently and safely draining water in a reservoir such as a river, a lake, a sediment dam, or a glacier lake.
