Description

  The present invention relates to a connected supply and flood control system that prevents flooding and flooding of rivers.

Measures against floods caused by heavy rain and river water floods include the installation of dams and river embankments to keep river water constant.
Normally, dams discharge the same amount as the inflow of the river at the dam site, or more than the inflow for the purpose of irrigation and maintenance of the river environment. However, when the inflow of the river is significantly increased due to heavy rain, etc., if the same amount of discharge is released, the river flow will increase in the downstream area and the water level will rise, increasing the risk of flooding. Become. Therefore, if the inflow exceeds a certain amount at the dam site, the discharge from the dam will not be increased further, and if the difference between the inflow and the discharge can be stored in the dam lake, the downstream river flow Becomes below a certain level, and further increase in water level can be prevented. There is a method based on this concept called flood control, which is called a constant rate and constant volume method, where the gate operation stores up to the peak flow rate at a fixed rate with respect to the inflow rate, and after the peak, a fixed amount of discharge is performed. There is an adjustment method to do. In addition, there is a so-called natural adjustment method in which flood control is performed by providing a discharge port at the dam's full water level (floor season limit water level) without gate operation. In recent years, small dams have been adopted nationwide.

It is characterized by that.

Here, the relay tank may not be provided with a water amount adjusting means for adjusting a flow rate such as an on-off valve or a valve.
Here, “the sea level (elevation height position) of the plurality of relay tanks is the same height” means that the height position of the amount of water from the bottom of the relay tank is within the same height position. As long as there is a certain amount of water in the plurality of relay tanks (if the high position and the upper side position are the same), there will be no problem in the size of the tanks or a slight shift in the vertical position.

  According to the present invention, since the height positions of the plurality of relay tanks are the same height position, the water level accumulated in the plurality of relay tanks is constant (the same position). The more the number is, the farther the area is located, the more water can be stored and relayed to prevent flooding and flooding of rivers and to send to drought areas, etc. Can do. According to the present invention, the connecting pipe or the relay tank does not require a water amount adjusting means for adjusting the flow rate of an on-off valve or a valve.

  Hereinafter, specific embodiments for carrying out the present invention will be described with reference to the drawings.

1-3 is a figure which shows the example in the case of applying this invention in a mountainous area.
The connected supply flood control system 1 of the present embodiment collects water from the river R in the relay tank 3 and supplies it to the plurality of relay tanks 3 through the pipes 5. The relay tank 3 has the same height above sea level (installed at the same altitude), and the bottom of the relay tank 3 is connected by a connecting pipe 5 (FIG. 1A). In addition, the side pipes of the plurality of relay tanks 3 may be the connecting pipe 6 that connects the bottom part side, or may be the connecting pipe 5 that connects the bottom part (FIG. 8B). In FIG. 1B, since the height of the water surface is the same even if the height of the plurality of relay tanks 3 is different, the upper part has the same height in order to eliminate waste in the height direction.

When connected as described above, the relay tank 3 to be connected can be sent to the connection pipe 5 and the relay tank 3 by removing the earth and sand by the water device 2 without providing an on-off valve. The relay tank 3 is connected to a water supply pipe 5b and a water supply relay tank, and may be supplied to the field, and may further be provided with a dam water storage pipe 5c (FIG. 8A). ). These pipes 5b and 5c may be provided with valves or valves.
Therefore, even if the river R due to heavy rain occurs, the water is carried to a clear area to prevent the river from overflowing or flooding. If this is supplied from the water supply pipe 5b to a field or the like, or transported over a long distance and carried to a drought area (a water shortage area under a hot sun), it will be a drought countermeasure.
Here, even if the connecting pipe 5 is arranged so as to hang down, water is supplied to the next relay tank 3. Therefore, for example, the water of the river R can be supplied to the remote islets S1, S2, S3 separated by the sea U using the connecting pipe 5 (FIG. 4B). Moreover, if the position of the relay tank 3 is arranged at a position near the top of the mountain (M1 to M3), water can be supplied to the area below the top of the mountain through the water supply pipe 5b (FIG. 8 (a) ( b)).
Further, even if the connecting pipe 5 is arranged so as to swell upward, water is supplied to the sequential relay tanks 3 (FIG. 3). However, in relation to the atmospheric pressure, the height of the connecting pipe 5 from the ground to 10 m or less is required. This is due to Trichelli's vacuum experiment, which is due to the liquid being pushed by air pressure (atmospheric pressure), but the condition that the connecting pipe 5 is filled with water is required.

The connecting pipe 5 is used only for connecting a plurality of relay tanks 3 and is not branched or connected to other pipes. You may connect with two or more. The magnitude | size of the diameter of the connecting pipe 5 is not ask | required, and the magnitude | size of a diameter may differ. If the connecting pipe 5 is a flexible hose (rubber, fire hose, etc.), it can be pulled out freely and stretched freely even if there are obstacles (wood, buildings, walls, etc.).
The water supplied from the river R maintains the same height position W by being connected at the same height position by the connecting channel 5 and the water channel system of the river R. The same sea level (same altitude position) may be any position K where the water amount W overlaps as shown in FIG. 2 (a), and all the relay tanks 3 must be completely at the same position. It does not mean, and the size (water storage amount) may be different. Although it is preferable that the height position W of the bottom part of each relay tank 3 is the same, it is difficult to actually arrange all of them according to geographical conditions (mountains, flat land, etc.). Therefore, as shown in FIG. 2A, as long as the height position W of the height (water volume) of the relay tank 3 serving as a reference is in the overlapping range, the relay tanks 3 having different height positions (altitude above sea level). It may be. Therefore, it becomes easy to install the relay tank 3 such that the height of the dam D and the dam D, the height of the pond / lake and the pond / lake, and the amount of water are the same.

  In the connected supply flood control system 1 of the present embodiment, when a plurality of relay tanks 3 at the same height are connected and water is introduced, all the relay tanks 3 have the same height (FIGS. 1A and 1B). . A plurality of relay tanks 3 and water from the river R are drawn into them. In the river R, a water intake device 2 is arranged to remove earth and sand and store in the relay tank 3. Even if it is connected to the dam D, pond or lake, the water is drawn. The dam D and the dam D, the height of the pond / lake and the pond / lake, etc. are few at the same position, but the amount of water can be maintained at the same height via the relay tank 3. According to the present embodiment, since the same water level is maintained according to the above principle, it is not necessary to use an on-off valve or the like, thereby enabling simple and inexpensive production. According to this embodiment, the more relay tanks 3 are provided, the more floods and rivers R can be prevented. Further, it is preferable that the plurality of relay tanks 3 are distant from each other and are connected to the river R at a position deviating from the position of the same weather so as to deviate from the position of rainfall.

  The water intake device 2 includes a water conduit 12 for flowing river water, a removal passage 13 for removing sediment from river water, and an earth and sand storage box 7 for collecting earth and sand, between the water conduit 12 and the removal passage 13. The removal net | network 7 is distribute | arranged (FIG. 5, FIG. 6, FIG. 7 (a) (b)). Further, the water wheel 10 rotates through the shaft 11 to secure the flow of water and push away the earth and sand. As the water wheel 10 rotates, dirt and the like can be washed away downstream. To prevent the river R, dam D, pond, lake, etc. from being eroded by the action of running water, rainwater, waves, etc., concrete blocks and natural stones 9 are installed on the dike surface and the riverbank, and gabions and futon baskets are installed. A sense of stability. And it is used aslant toward the downstream (FIGS. 7A and 7B). The water intake device 2 can be made the same as the water level W of the relay tank 3 if installed at a different inclination. Further, it is possible to adjust the amount of water in the water intake device 2 by providing the supply pipe 2a and the return pipe 2b and controlling them by the control means (FIG. 5).

  As the relay tank 3, a temporary relay tank such as a pool or an unused field can be used. And these are connected with the connecting pipe 5, and are made into the state which can be used suitably with a valve | bulb. In addition, it is designed to be a place that can be used as a temporary relay tank 6 in a predetermined range (where it is used for parking lots, grounds, parks, etc. during normal times). Can also be used. You can also use high water fountains such as grounds and parks (sites that are one step higher than low water channels where water flows). In these temporary relay tank 6 and relay tank 3, water is collected using rivers, ponds / lakes and water intake device 2. That is, the temporary relay tank 6 and the relay tank 3 are connected to the water collecting pipe 51 and the connecting pipe 52.

  In addition, in order to prevent flooding in the plains, water is sent to areas that are not affected by flooding. That is, it connects with the relay tank 3 and the river R which are installed as far as possible through the connecting pipe 5. Since the relay tank 3 and the river R in the remote area are not affected by flooding, draining from there does not affect flooding or flooding.

  These relay tanks 3 collect water using rivers R, ponds and lakes, and a water intake device 2, and these relay tanks 3 are connected to a water collecting pipe 51 and a connecting pipe 53 (FIG. 5 to FIG. 5). 8). The dam D, the pond / lake, the relay tank 3, and the relay tank 3 and the relay tank 3 are arranged so as to have the same sea level (the same altitude position).

The relay tank 3 of the present embodiment is installed on the ridge L1 in the mountainous area (FIG. 10). Moreover, FIG. 11 is a figure of the state which wrote the ridge line L1 in the actual map of the mountain part of Toyama Prefecture, and installed the relay tank 3 and the pipe | tube 5. FIG.
Here, the ridge is a general term for a convex portion on a line connecting a protruding portion sandwiched between valleys, such as a summit, a peak, and a ridge. For a point where the river R is located, the entire region where rainfall flows out to that point is called a catchment area or catchment area (a range surrounded by reference numeral L1), and the area is called a catchment area. In the present embodiment, the position of the relay tank 3 is arranged at the position of the mountain ridge L1 in order to exclude the water collection area or the water collection area. Accordingly, the relay tank 3 is unlikely to run out due to rainfall.

The ridge line L1 is a place where places higher than the periphery are continuous, and becomes a watershed (boundary lines of a plurality of catchment areas) (the ridge line L1 is surrounded in FIG. 10). Since rainwater does not move beyond the ridge line L1 having a relatively high altitude, it flows down the valley line L2 in the range surrounded by the ridge line L1.
Looking at the flow of rainwater that has fallen at points (1) to (4), the position of (1) flows upward in the figure because there are ridge lines L1 on the left, right, and bottom. There are high peaks and ridges on the lower side, and they do not flow into the valley on the X side. The position (2) flows downward in FIG. 10 because the ridge line L1 is on the left, right, and top. The ridge line L1 passes on the right side and does not flow into the valley on the X side. The position (3) flows to the right in the figure because there is a ridge line L1 on the left, top, and bottom. Since the ridge line L1 passes through the lower left side, it does not flow into the valley on the X side. Since the ridge line L1 is on the left, right, and top, the position of (4) flows downward in FIG. 10 and reaches X through the valley line L2. Therefore, (4) falls within the X catchment area. In this way, the range surrounded by the ridge line L1 and the summit that passes closest to the upstream side of X is the water collection area of the X point, and rainwater falling in this area gathers at the X point.
Therefore, if the relay tank 3 is provided in the ridge L1, it will remove | deviate from a catchment area. In the present embodiment, the position of the relay tank 3 is arranged at the position of the mountain ridge L1 in order to exclude the water collection area or the water collection area. Thus, it is preferable to arrange so that two may face each other at the same sea level (elevation position) at the position of the left and right ridges across the valley L2.

  As described above, the present invention is not limited to the embodiment described above. For example, in combination with the first embodiment and the second embodiment, the first embodiment in a mountainous area and the second embodiment in a plain area may be connected. The more relay tanks 3 and temporary relay tanks (dams, etc.) 6 at the same height, the more floods and rivers can be prevented, and the water stored in the relay tanks can be used for agriculture and industry. Become. Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
