Description

The present invention relates to an embankment raising device that siphons the amount of water on a storm surge or flood side and raises the top of the embankment to a predetermined height.

The main cause of damage in Japan is disaster caused by heavy rain. In addition to flood disasters that cause river inundation and levee breaks (breakdowns), landslides such as slope failures and debris flows, there are overtopping waves that are accompanied by storm surges due to strong winds associated with typhoons. These overtoppings are often considered to be heavy rain disasters. This overtopping is a seawater intrusion beyond the seawall, and if the amount of intrusion is large, it will cause serious damage and damage to the submerged houses and infrastructure such as substations, railways and roads.

Until now, in the case of flood disasters in Japan, in order to protect human lives and infrastructure safety from river flooding and bank breakage, etc., sandbags filled with fillers such as earth and sand have been stacked in traditional heavy bags such as hemp bags, etc. Has raised the top of the. Alternatively, a floodgate has been provided to block the inundation channel.

For example, in the ones disclosed in Patent Documents 1 and 2, a bag filled with a water-absorbing polymer material is provided on a dike that is expected to be flooded, and the volume and weight thereof are reduced by absorbing the increased amount of water. The one which is increased and used as a conventional sandbag has been proposed.

Moreover, in what was disclosed by patent document 3, the floating body mechanism inserted in the inside of a floating body apparatus raises by the water flow which flowed in, and what interrupts the course of a flood by ensuring required height is proposed. Yes.

In the conventional method of stacking sandbags as described above, a large amount of sandbags are created each time heavy rains occur, and it takes a lot of labor and time from transportation and installation to the levee etc. Also included a problem that had to be dealt with. In addition, the floating body mechanism is raised by the inflow of increased water to block the inundation channel, which causes a problem that much cost and labor are spent on installation of equipment, and there is a concern that the scenery will be damaged.

The present invention intends to solve the problems of the conventional configuration, and the construction method of stacking sandbags containing earth and sand in a strong bag such as a traditional hemp bag as a flood countermeasure is the work itself Included the problem of danger. Therefore, by introducing siphons for the amount of water on the storm surge or flood side, the volume and weight of the raising means are increased through the water storage means, and the top of the embankment is raised to a predetermined height without going to the danger zone. The purpose is to realize.

In addition, the amount of water introduced into the water storage means is prevented from being supplied to the irrigation water and drained to the low water surface side by time, thereby preventing the bank breakage in the downstream area and draining the sedated water to the low water surface side. By blocking and supplying irrigation water in the area in a timely manner, water can be used for drought countermeasures and fire prevention.

In order to achieve the above object, the present invention forms an introduction hole that penetrates from the inner slope to the outer slope of the levee, and the surface that communicates with the introduction hole and contacts the outer slope is flat. A horizontally long bag-like raising means with a flat surface installed at the top of the dike communicating with only one of the bag-like water storage means and the introduction hole is provided, and the internal pressure is set at the ceiling of the raising means. There is provided a levee raising device which is provided with a relief valve which keeps a set pressure while avoiding the above rise and which increases the volume and weight of the raising means through the water storage means.

In addition, the second problem solving means is that the water storage means prevents the supply of the introduced water to the irrigation water, etc., and drains the lag water to the low water surface side, and also prevents the sedated water from draining to the low water surface side. In addition, a directional control valve is provided to supply irrigation water in a timely manner.

The third problem-solving means is a plate in which the direction control valve is provided with a short cylindrical extension pipe at a connection portion communicating with the introduction hole, and is reduced toward the extension direction of the introduction hole on one end side of the extension pipe. The tapered wall is joined and the end of the tapered wall at the end of the tapered wall is inserted into the end of the introduction hole. In the space where the tapered ends of the tapered wall face each other, the taper wall has an inverted L shape as viewed from the side protruding through the extension tube. A spherical supply pipe is provided, a return spring means is provided in the above-mentioned facing space, and a spherical surface in which one side of the reduced wall end of the taper wall and the inlet of the supply pipe is inflated outwardly by connecting to both ends of the return spring means. A plate-shaped valve seat having a shape is built in, and a connection type operating rod for sequentially opening one of the valve seat and the other valve seat is provided.

The operation of the first problem solving means is as follows. In other words, by introducing siphons for the amount of water on the storm surge or flood side, the top and bottom of the dike can be raised to a predetermined height without going to the danger zone by increasing the volume and weight of the raising means through the water storage means. .

Further, the action of the second problem solving means is that the direction control valve can drain the amount of water introduced into the water storage means to the low water surface side by time while preventing the supply to the irrigation water or the like. Alternatively, the water stored in the water storage means can be supplied to irrigation water and the like in a timely manner while preventing drainage to the low water surface side.

However, the action of the third problem solving means is that the directional control valve is simplified to lower or raise the operating rod procedure, so that either one of the valve seat and the other valve seat is opened in order. Can be implemented.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes an embankment raising device, as described in the claims, “forms an introduction hole 2 penetrating from an inner slope of an embankment toward an outer slope, and communicates with the introduction hole 2. A horizontally long bag-shaped raising means in which the surface to be installed at the top of the dike communicating with only one of the bag-shaped water storage means 4 and the introduction hole 2 whose surface contacting the outer slope is flat 5 is provided, and the top end of the raising means 5 is provided with a relief valve 5b that keeps the internal pressure from rising to a set value or higher and increases the volume and weight of the raising means 5 through the water storage means 4. ”.

The above-mentioned embankment raising device 1 is designed to increase the volume and weight of the raising means 5 through the water storage means 4 by introducing a siphon of the amount of water on the storm surge or the flood side, so that the top of the embankment can be used in response to sudden water increase. It is intended to raise to a predetermined height.

In FIGS. 1 and 2, reference numeral 2 denotes an introduction hole, which penetrates the middle of the bank body, and lays polyethylene pipes excellent in earthquake resistance from the outer slope surface to the inner slope face. The laying height of the introduction hole 2 is set to the low position on the inner slope side. As shown in FIG. 2, the introduction hole 2 communicates with the water storage means 4, and the raising means 5 communicates with the water storage means 4. Alternatively, the raising means 5 can communicate with the introduction hole 2 when the height difference between the outer slope of the dike and the dike ground is small.

The introduction hole 2 is described as an example of the laying method. For example, a cutting tool is connected to the tip of a pressure steel pipe or the like, and a pressing force and a rotational force are applied to the pressure steel pipe by a propulsion method or the like. Penetrate to the slope. Next, the polyethylene pipe is connected to the tip of the pressure steel pipe from which the cutting tool has been removed, and then the connected polyethylene pipe is slip-laid in accordance with the timing of pulling out the pressure steel pipe. Note that the outer diameter of the pressure steel pipe and the outer diameter of the polyethylene pipe may be equal to each other as much as possible, and a corrosion-resistant pressure steel pipe may be directly laid instead of the polyethylene pipe.

Here, the introduction hole 2 covers a wire mesh 2c having a lattice-like shape (for example, a gap between lattices of about 1 mm to 5 mm) on a tip 2a (protruding portion) that protrudes toward the sea side or the river side. The fixing band 2d is tightened and fixed around the neck. This prevents intrusion of wreckage and wood edges. The wire mesh 2c is made of aluminum bronze having good corrosion resistance and wear resistance.

The above-mentioned aluminum bronze is a Cu alloy containing 5 to 11% of Al (containing a small amount of Fe, Mn, Ni), and the component invented by Jun Asato is also called Arms bronze, and has a good spreadability. . Moreover, since the crystal grain becomes coarse in the as-cast one, Fe, Mn and the like are added. Good workability, high strength, good corrosion resistance and wear resistance. Machined materials are used for machine parts and marine parts, and cast materials are used for gears, bearings, bushes, and the like.

2, 3, and 7, 4 is a water storage means, which is provided in a bag shape (for example, an arc-shaped horizontal section) with a flat surface in contact with the outer slope, and has the same specifications as a fire hose. A sheet layer is composed of a rubber sheet on the interior of the fabric and cotton striking cords knitted on the exterior, and it can withstand the introduction pressure and water storage pressure for several hours to several weeks when introducing a siphon. Can do. Moreover, the water storage means 4 is made as thin as possible (for example, 1 mm or less) within a range satisfying flexibility and durability. In addition, the purpose of reinforcing the levee body is given, and the volume and installation area are secured according to the reinforcement.

The water storage means 4 is connected to the introduction hole 2 via a connecting metal fitting 4a having good corrosion resistance (for example, a connecting metal for connecting fire hoses to each other and made of aluminum die cast) at a site installed on a seawall. It communicates with the end 2b. As shown in FIG. 3, the water storage means 4 is preferably formed in a bellows bag shape, and a coil-shaped spring steel or ring-shaped spring steel wound in a spiral shape has a certain distance on the outer peripheral surface. It is laid and knitted. As a result, it can be extended and contracted to ensure a required length and a predetermined intake air amount when extended. The surface is coated with a weather resistant resin material to prevent deterioration.

In addition, the water storage means 4 is placed on a pedestal 4c (for example, a porous elastic rubber having a hollowed center at the top and a concrete solidified in a mold) in the installation portion, and the other water storage means 4 and They are placed on the outside slope at a certain interval and are lined up. Further, a lower portion of the water storage means 4 is provided with a fastener 4b that can be opened and closed to discharge muddy water or a mud layer generated when the water is stored when necessary. This water storage means 4 can be thrown down from the top of the bank with the outer slope facing the back after transportation and carry-in, and intake air can be sent from the attachment part of the connection fitting 4a and the connection fitting 5a to expand.

As shown in FIG. 7, the water storage means 4 is a string in which the water storage means 4 and the other water storage means 4 are in contact with each other in order to prevent the collapsing caused by strong winds even after the volume and weight are increased. 4d is provided. An ear sheet 4c is attached to the water storage means 4 at an appropriate position, and a transfer rope 4d is wound around a fastener 4f provided on the ear sheet 4c.

The above spring steel includes medium-high carbon steel containing 0.5 to 10% of carbon, Si-Mn, Mn-Cr, Cr-V, Mn-Cr-B, Si-Cr, Cr-Mo. A total of nine types of alloy steels to which etc. are added are defined by JIS. Suitable for spring manufacturing process: 1 material-hot / cool forming-quenching / tempering 2 material-patenting treatment-cold processing, 3 materials-quenching / tempering-cold forming Is selected.

The rubber sheet is formed from a porous elastic rubber molded body (for example, a spring constant of 0, 49 to 4, 7 kN / cm), and has acid resistance, alkali resistance, water resistance, microbial resistance, and oil resistance. It is a material that has excellent properties, organic solvent resistance, and compression resistance, and does not deform itself, and has little plastic deformation in repeated compression over a long period of time. Moreover, since it is necessary to endure the shearing force by a horizontal load, the shear elastic modulus is set to 0, 1 to 0, 7 N / mm2.

In addition, when the porosity of the porous elastic rubber is less than 5%, the equivalent damping coefficient becomes small and it becomes impossible to remove compression repeatedly. When the porosity is more than 50%, the compression strength is insufficient. In addition, in the range of the porosity of 5 to 50%, a material adjusted to a porosity having a predetermined flexibility and durability is used so that the strain can be 5 to 15%.

2, 3, and 6, 5 is a raising means, and a surface to be installed on the top end of the dike is provided in a horizontally long bag shape having a flat surface (for example, an arc-shaped cross section). The sheet layer is composed of a rubber sheet in the interior of the fabric and cotton cords woven in several layers in the exterior. The raising means 5 communicates with a communication fitting 5a attached to the upper part of the water storage means 4 (for example, the same standard product as the connection fitting 4a). Further, the raising means 5 is arranged in series with other raising means 5 at the top of the bank without any gap. Detailed drawings and explanation of specifications of the connecting bracket 4a and communication bracket 5a are omitted.

The above raising means 5 introduces and expands the air sucked into the water storage means 4 by introducing a siphon of the amount of water on the storm surge or flood side, and further, the air is compressed by introducing the siphon. The top end is provided with a relief valve 5b in which the internal pressure is required to open and close quickly with a set value as a boundary. Further, the raising means 5 is made as thin as possible (for example, 1 mm or less) within a range satisfying flexibility and durability. In addition, the height when the raising means 5 is expanded is set to approximately 1.0 m, and the laying length is set to a predetermined height of 5,000 m or less.

The relief valve 5b described above is made of aluminum die cast with good corrosion resistance at the site where it is installed on the seawall, so that the internal pressure can be prevented from rising above the set value and kept at the set pressure. it can. Here, the set pressure will be described. When the height when the raising means 5 is expanded is within 1 and 0 m, the set value can be adjusted within the range of 0, 1 to 0, 125 MPa [gauge pressure]. In addition, since the off-the-shelf product is used, the explanation and detailed drawings are omitted.

Further, as shown in FIG. 6, the raising means 5 together with the other raising means 5, after increasing the volume and weight, prevents slippage or loss when subjected to storm surge or flood water pressure. Therefore, a block 5d installed or embedded on the inner slope of the dike (for example, a concrete or wire net packed with a heavy object such as a stone) and suspended from a hanging tool 5e (for example, In the case of a river, the string-shaped cord 5c is urged in a slanting direction in the downstream direction). Alternatively, the base end may be connected to a storage box (not shown) fixed to the top end of the dike for each laying length, and the tip extended to the top end may be connected to another storage box.

In addition, the raising means 5 is provided with an end sheet 4c with a fastener 4f provided on the end portion joined to the other raising means 5 and the water storage means 4 in order to enhance the installation stability (for example, the outer slope side). The string-shaped string 5c is urged between the hanging tool 5e that suspends the block 5d embedded in the base portion of the base 4e via the via. Instead of the block 5d, it may be connected to an unillustrated pinch metal fitting for pinching the concrete paved levee side end.

That is, the embankment raising device 1 increases the volume and weight of the raising means 5 through the water storage means 4 by introducing a siphon of the amount of water on the storm surge or the flood side, so that the top of the embankment can be used in response to sudden water increase. It can be raised to a predetermined height.

3, 4, and 5, 3 is a directional control valve. As described in the claims, “the water storage means 4 prevents the supplied water amount from being supplied to irrigation water and the like to the low water surface side. In addition to draining time difference, the directional control valve 3 for supplying sedated water to irrigation water etc. in a timely manner by blocking drainage to the low water surface side… Some omitted… is a short cylindrical shape at the connection part communicating with the introduction hole 2 A plate-like taper wall 3d that shrinks in the extending direction X of the introduction hole 2 is joined to one end side of the extension pipe 3a, and the divergent end side of the taper wall 3d is connected to the introduction hole 2 at one end side of the extension pipe 3a. In addition to being inserted into the terminal 2b, a cylindrical supply pipe 3h having an inverted L shape when viewed from the side protruding through the extension pipe 3a in a space where the reduced end of the tapered wall 3d faces is provided in the above-mentioned facing space. The return spring means 3g is built in and connected to both ends of the return spring means 3g. A plate-shaped valve seat 3e and 3f each having a spherical shape in which one side that closes the reduced end of the super wall 3d and the pipe port of the supply pipe 3h bulges outward is incorporated, and any of the valve seat 3e and the other valve seat 3f It has a connected operation rod 3i that sequentially opens one of the valves. "

The directional control valve 3 is intended to drain the amount of water introduced into the water storage means 4 to the low water surface side while preventing the supply to irrigation water or the like. Alternatively, the sedated water stored in the water storage means 4 is timely supplied to irrigation water or the like while preventing drainage to the low water surface side. However, by simplifying the procedure of the operating rod 3i to be lowered or raised, one of the valve seat 3e and the other valve seat 3f is opened in order.

4 and 5, reference numeral 3a denotes an extension pipe, which is interposed in a connecting portion (for example, a connecting metal fitting 4a) where the water storage means 4 and the introduction hole 2 are connected. The extension pipe 3a is formed by casting or reinforced plastic molding. The body is formed into a short cylindrical shape. Here, the communication with the introduction hole 2 is performed by tightening the tightening bolts (not shown) of the connection band 3c in which the extension pipe 3a and the end 2b of the introduction hole 2 are abutted and both pipe ends are fitted. . In addition, a rubber packing (not shown) is provided in each of the butted pipe ends to prevent water leakage.

The extension pipe 3a is connected to the water storage means 4 because a simple connection is required in preparation for an emergency, so that the water storage means 4 and the terminal 2b of the introduction hole 2 have the same shape. It is attached using a connecting fitting 4a (for example, an aluminum die-casting fitting for connecting fire hoses to each other and the same standard product).

Further, the extension pipe 3a is joined with a plate-like taper wall 3d that uniformly shrinks toward the feeding direction (for example, the extending direction of the introduction hole 2) on one end side (for example, after the interior parts are assembled, the equal division 3 ˜6 directions are connected), and the divergent end side of the tapered wall 3d is inserted into the terminal 2b of the introduction hole 2. Further, the pipe port of the supply pipe 3h is opposed to the space where the reduced ends of the tapered wall 3d face each other. Moreover, the return spring means 3g is provided in the facing space.

The supply pipe 3h is integrally formed with the extension pipe 3a, and is formed in a cylindrical shape having an inverted L shape when viewed from the side penetrating the extension pipe 3a and projecting downward. The pipe end of the supply pipe 3h is directed to the upper part of the U-shaped groove embedded in the outer slope of the embankment (not shown), so that the sedated water is supplied to irrigation water connected through the U-shaped groove. The In addition, it may replace with a U-shaped groove and may lay polyethylene pipes.

The return spring means 3g is formed in a coil shape in which a single spring steel is spirally wound, and is interposed in a space where the reduced end of the tapered wall 3d and the tube opening of the supply pipe 3h face each other. . The return spring means 3g has a return force that always returns to its original position due to the effect of an appropriate spring function, so that a plate-like plate shape in which one side swells outward at both ends of the return spring means 3g. The valve seats 3e and 3f are connected. Thereby, the repulsive force which arises at the time of the initial compression to the return spring means 3g is given to the valve seats 3e and 3f.

In FIG. 5, 3e is a valve seat on the introduction hole 2 side, and 3f is a valve seat on the supply pipe 3h side, which is formed from a cast or reinforced plastic molded body. The valve seats 3e and 3f are in close contact with the reduced end of the tapered wall 3d and the inlet of the supply pipe 3h, and both ends of the return spring means 3g are connected to the inner side surfaces of the valve seats 3e and 3f, so that the valve seat 3e However, the reduced end of the taper wall 3d and the other valve seat 3f close the pipe port of the supply pipe 3h.

The above-described valve seats 3e and 3f will be described. Normally, the valve seat 3e and the other valve seat 3f block the reduced end of the tapered wall 3d and the inlet of the supply pipe 3h. During the heavy rain occurrence period, the valve seat 3e that has closed the reduced end of the tapered wall 3d is opened. When supplying to irrigation water or the like, the valve seat 3e and the other valve seat 3f are operated according to the order because the valve seat 3f that has closed the pipe port of the supply pipe 3h is opened. A connection type operating rod 3i is provided.

In FIG. 5, 3i is an operating rod, one end is provided with a lateral rod 3j that is narrowly inserted into a central portion of the valve seats 3e and 3f and accommodated within a predetermined position, and the other end of the lateral rod 3j is a supply pipe The slanted rod 3m is connected to one end of the oblique rod 3m that is obliquely passed through the bent portion of 3h so that it can be engaged with each other, and the middle point of the slanted rod 3m is rotatably coupled to one end of the support rod 3k. Is fixed to the farthest end of the bend of the supply pipe 3h so as to be rotatable, and the other end of the oblique rod 3m is rotatably connected to one end of the longitudinal rod 3n and bent into a U-shape. The other end of the directional rod 3n is pivotally connected to one end of the slanting rod 3p, and the other end of the slanting rod 3p is coupled to the intermediate point of the bar lever 3q so that the lever can be used. Is fixed to the outer peripheral wall of the supply pipe 3h so as to be rotatable.

Here, as shown in a balloon diagram shown in FIG. 5, in order to enable parallel movement of the lateral rod 3j (for example, movement along the central axis of the supply pipe 3h), a standard gear is provided at the other end of the lateral rod 3j. A right lower -45 ° split gear 3r is formed, and an upper right 45 ° split gear 3s is formed at one end of the oblique rod 3m. Further, bearing holes 3t and 3u are formed in the shaft centers of the meshed split gear 3r and the split gear 3s, respectively, and a U-shaped bar-like support pin 3v is inserted into the support holes 3t and 3u. However, C-shaped plate-shaped retaining rings 3w and 3x for preventing falling off are respectively fitted to both ends of the support pin 3v.

The meshing angle (for example, θ = approximately 45 °) of the split gear 3r at the lower right of −45 ° will be described. The other end of the lateral rod 3j is in the vertical direction (for example, the upper end surface forming a right angle with the horizontal plane). The meshing angle (for example, θ = approximately 45 °) of the split gear 3s at the upper right 45 ° having the same pitch as that of the split gear 3r is 180 ° to approximately 135 °. By forming one end in the range of 0 ° to about 45 ° with respect to the vertical direction (for example, the upper end surface perpendicular to the horizontal plane), the swing angle θ of the oblique rod 3m is maintained at 90 °.

Next, the longitudinal rod 3n passes through the central axis of the supply pipe 3h, and the other end of the supply pipe 3h is wrapped around the end of the supply pipe 3h so that one end of the bar lever 3q is rotatably fixed. The inside is inserted. Further, the other end of the vertical rod 3n is rotatably connected to one end of the slanting rod 3p, and the other end of the slanting rod 3p is coupled to the intermediate point of the bar lever 3q so that the lever can be used. Thereby, one end of the oblique rod 3m connected to the longitudinal rod 3n can be bent, and the oblique rod 3m can bend the transverse rod 3j engaged with the rod. Accordingly, the lateral rod 3j enables translation along the central axis of the extension pipe 3a.

Explaining the operation rod 3i, the rod lever 3q to be operated needs to be temporarily fixed when using the lever from the horizontal position. Upper, middle and lower stopper grooves, not shown, are provided on the inner arc line, and hemispherical metal balls (not shown) that are semi-fitted to the stopper grooves are formed at one end of the rod lever 3q. . This realizes temporary fixation at the time of raising, leveling, and lowering. In addition, as a countermeasure against slipping, the other end of the bar lever 3q is processed by covering it with an uneven rubber sheet or the like, and in the case of a foot tip operation, a ring-type pedal system is adopted.

The above castings are cooled after pouring cast iron or cast steel melted into the mold, molding sand called casting sand and breaking the mold after each casting, or molding the mold by sand molding method Some molds are made using molds made of metal or metal. Cast iron and brass are used for this type of material. The extension pipe 3a, the tapered wall 3d, and the like are produced by making a mold using a precision casting or a molding machine that produces a clear surface.

The above-mentioned reinforced plastic (FRP) is made of an unsaturated polyester resin that can be cured at room temperature and pressure, and can be easily and mass-produced from extrusion molding, compression molding, injection molding, and mold molding. Choose an excellent one. This FRP has features such as easy processing, low cost, light weight, high strength, and resistance to corrosion.

The procedure of the operation rod 3i described above will be explained. During normal times, the valve lever 3q is placed in the horizontal position by setting the bar lever 3q to the horizontal position, so that the valve seats 3e and 3f are freed from the reduced end of the tapered wall 3d and the pipe port of the supply pipe 3h. To prevent entry of small animals. At the time of flooding, the lever rod 3q is leveraged to the lowered position so that the lateral rod 3j slid to the water storage means 4 side opens the valve seat 3e that has closed the reduced end of the tapered wall 3d. . Then, in addition to siphoning the amount of water on the flood side through the opened gap, it is possible to prevent the supply of the introduced amount of water to irrigation water and the like to perform time-lag drainage on the low water surface side.

Next, when drought measures are taken, the bar lever 3q is used in the horizontal position to reduce the amount of water (muddy water) introduced into the water storage means 4 and then the bar lever 3q is used in the raised position to use the lever. The lateral rod 3j slid toward the introduction hole 2 pushes up the other valve seat 3f that has closed the pipe port of the supply pipe 3h to open the valve. Then, the stored water that has been sedated through the opened gap can be supplied to irrigation water and the like in a timely manner by preventing drainage to the low water surface side.

When the operation rod 3i is an electromagnetic type, a linear motion electromagnetic coil is incorporated at the other end of the longitudinal rod 3n so that the valve can be switched by an electric signal from an electric circuit. This direct acting electromagnetic coil has a simple structure and is reliable in operation. Further, as an operation mechanism that can be applied to control by a computer signal, there are a coil with a surge voltage prevention mechanism or a built-in low power consumption type coil.

That is, the direction control valve 3 can drain the amount of water introduced into the water storage means 4 to the low water surface side by time while preventing supply to irrigation water or the like. Alternatively, the sedated water stored in the water storage means 4 can be supplied to irrigation water and the like in a timely manner while preventing drainage to the low water surface side. However, by simplifying the procedure of the operating rod 3i to be lowered or raised, it is possible to open one of the valve seat 3e and the other valve seat 3f in order.

The operation of the above configuration will be described below. That is, by introducing siphons of storm surge and flood-side water volume, the volume and weight of the raising means 5 are increased through the water storage means 4 so that the top of the dike is raised to a predetermined height in response to sudden water increase. can do.
