Description

[Technical field]

[0001] The present invention relates to a water injection and confluence member, a siphon water supply device, and a siphon water supply method using the same. [Background technology]

[0002] A siphon water supply device is a device that uses a tubular member installed between a water storage section in a high water level area and a low water level area to supply water from the water storage section in the high water level area to the low water level area by siphon action. The inventor has proposed a water injection and confluence member as one of the members that activates and operates the siphon action (Patent Document 1).

[0003] The inventor has invented and obtained a patent for a siphon water supply device that supplies water by connecting a siphon water supply pipe (including a hose) directly to a water supply device, and when the water supply pipe is full of water, the power supply device is turned off and the device switches to siphon action. However, this siphon water supply device uses a submersible pump as the water supply device, and after switching to siphon water supply, the water supply device (submersible pump) becomes the siphon water intake part. If dirt gets stuck in the small holes of the strainer installed in the intake part of the submersible pump during siphon operation, the water supply stops, and maintenance work to remove the dirt is necessary and troublesome. Therefore, a "Y"-shaped water injection merging component was developed to be placed at the highest part of the piping. This water injection merging component is structured so that a water injection pipe (hose) that pours water from the water supply device is connected to one of the upstream forks, and a siphon water intake pipe (hose) is connected to the other fork to merge in a Y shape, and the siphon water supply pipe (hose) is connected to the downstream side to supply water. One of the features of the structure of this water supply device is that the water supply device's water inlet pipe and the siphon's water suction pipe are constructed separately, eliminating the need to attach a strainer to the siphon water inlet, and the siphon water inlet can be opened wide, preventing debris from clogging the water inlet hole during siphon water intake. Since it is difficult for the siphon to supply water by itself when the head exceeds 7m, the inventor discovered that in that case, the siphon action can be sustained even at high heads by using a water supply device in combination with the siphon action to inject water into the water inlet junction, and obtained a patent for this discovery.

[0004] When using the siphon water supply device according to Patent Document 1, the necessary components for the siphon water supply device, such as the water supply device, siphon water suction pipe, water suction dustproof basket, water supply device connection member, siphon water supply pipe, water injection junction member, and backflow prevention device, were delivered to the site before being assembled, and then assembled on site and immersed in the water storage unit in order for installation and use. Therefore, when used on site for the first time, it was difficult to assemble unless an experienced person provided technical guidance on the assembly procedure. In addition, as shown in Figure 12, the water injection junction member 130, which is approximately "Y" shaped or katakana "T" shaped, was installed near the highest part of the piping, so that two hoses, the submersible pump water injection hose 140 and the siphon water suction hose 150, had to be connected to the openings of the two branches of the water injection junction member 130 between the water reservoir 101 and the water injection junction member 130.

[0005] Furthermore, in the siphon water supply device described in Patent Document 1, although each component is connected, it is not possible to fix the individual components in the overall configuration obtained by assembling them together. Therefore, when installing against a vertical wall or a wall surface that is nearly vertical, each component of the siphon water supply device, such as a submersible pump, and the water injection and merging component, is attached with a hanging rope of an adjustable length, such as a wire rope, and further, for example, a length adjusting member such as a tamper evident, is used to hang the components so that the load is evenly distributed across each component, or the necessary scaffolding, anchoring, fixing materials, etc. are used for installation, and the device is installed as follows:

[0006] First, to install piping on a wall in the air, as shown in Fig. 13, anchors are driven into the wall and scaffolding 202 is assembled and fixed, and workers use this scaffolding 202 to install piping materials 203 such as hoses and tubular members. Next, anchor holes are drilled into the wall using connecting joints 204, and anchors 205 for fixing the piping materials are driven in to fix the piping materials 203. By repeating this process, piping materials 203 of a predetermined length are connected in order, and the piping length is extended. This work process has the disadvantage of being expensive to install.

[0007] Next, when piping is to be installed on a vertical wall underwater, a diver drills holes in the wall underwater to provide anchor holes, and installs piping anchors 206 in the holes using a filler such as Chemical Anchor (registered trademark), as shown in Figure 13. Pipe materials 203 of a specified length are connected in sequence using connecting joints 204 to extend the piping length. This kind of underwater anchor hole drilling work is harder than one might imagine, and only qualified personnel can carry out the work, which creates the problem of high construction costs.

[0008] [Patent Document 1] JP 2014-196656 A Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made in consideration of such problems. First, the shape of the water injection junction member, which was previously bifurcated, has been changed to a cylindrical water injection junction member structure equipped with a check valve that rotates inward on the side of the main body of the water injection junction member, and it is connected to the water supply device directly or via a water supply device connection member. The previous two-pipe structure from the water supply device to the water injection junction member and from the siphon water intake section to the water injection junction member has been changed to a single-pipe structure, which eliminates the need for a water intake pipe (hose), thereby reducing costs. In addition, the water injection junction member, which was previously located at the highest part of the piping, can now be connected closely to the water supply device and placed inside the water storage section, which has also led to simplification of the installation work. For example, when installing on a vertical wall surface or a wall surface close to vertical, it is now possible to easily install the siphon-activated water supply member by fixing it inside the storage frame and hanging the storage frame as it is with a wire rope or the like. This makes it possible to shorten the construction period and reduce construction costs by eliminating the need for scaffolding and its assembly work, as well as the work of fixing the water supply pipe to the wall, which was previously required. Also, by shipping the storage frame with the necessary parts for the siphon water supply device assembled and fixed inside it at the shipping source, it becomes unnecessary to go to the site to provide technical guidance for assembly work, etc. [Means for solving the problem]

[0010] In order to achieve the above-mentioned main object, the present invention adopts the following means. The water injection and confluence member according to the present invention is The upstream opening is connected to the water supply device directly or via a water supply device connecting member, and the downstream opening is connected to the siphon water supply pipe and is a substantially cylindrical water injection and confluence member disposed in the water storage section, The water injection and merging member has a siphon water intake opening on a side thereof for suctioning water from the water storage section by siphon action, The upstream portion of the siphon water intake opening is provided with a check valve having a hinge structure which is pushed by the water pressure in the reservoir and rotates inward of the water inlet and outlet member when the water pressure inside the water inlet and outlet member becomes lower than the water pressure in the water reservoir, which is the outside.

[0011] The water injection and merging member according to the present invention has a cylindrical shape, and therefore can be manufactured compact and lightweight compared to conventional Y-shaped or U-shaped water injection and merging members, and therefore the labor required for installation in the water storage unit can be reduced.

[0012] The check valve provided on the side of the main body of the water inlet and outlet member may be provided with a storage section protruding laterally in order to prevent the check valve from closing a part or the whole of the water flow cross section inside the main body of the water inlet and outlet member when the check valve rotates to open. The water inlet and outlet member provided with a siphon water intake port equipped with a check valve on the side may be linear or curved. The cross-sectional shape is not limited, and may be cylindrical, square, or a combination of these.

[0013] The shape of the check valve may be circular, elliptical, polygonal, or a combination of these, and the surface of the check valve may be flat, curved, or a combination of these. In addition, the check valve may be a member that was originally cut out when making the opening in the water injection junction member.

[0014] The present invention further provides a siphon water supply device using the above-mentioned water pouring and merging member. The siphon water conveying device according to the present invention is A siphon water conveying device that conveys water from a water storage section in a high water level area to a low water level area located lower than the high water level area, This water inlet and outlet junction member has a water storage section for a high water area, an upstream opening and a downstream opening having connecting parts on the upstream and downstream sides, and a siphon intake port on the side of the water inlet and outlet junction body that draws in water from the water storage section, and is equipped with a check valve having a hinge structure that rotates inward on the upstream part of the outer periphery of the contour of the siphon intake port, a water supply device connected directly or via a water supply device connecting member to the upstream opening having the connecting part of the water inlet and outlet junction member, and a siphon water supply port formed at the downstream opening. The siphon start water supply unit is immersed in water and installed with a siphon water supply pipe that is installed as a single piping and extends from the highest part of the piping to the downstream outlet, connected to the downstream opening of the water injection junction member, and is characterized in that a siphon start water supply unit is installed by immersing it in water, and a siphon stop air suction member is provided at or near the highest part of the siphon water supply pipe.

[0015] When using this device, the water supply equipment and the water injection junction member equipped with a check valve on the side of the main body are connected together and placed underwater in the water storage section. Therefore, when the head is 7m or less, the siphon water supply pipe is filled with water by the water supply equipment, and then when the water supply equipment is stopped, the siphon flow is automatically started by the function of the internal switching valve of the water injection junction member.

[0016] In addition, since the water supply device using the water injection merging member of the present application can use the siphon action and the water supply action of the water supply device in combination, when performing water supply work under conditions of a head of 7m or more, by using a water supply device with a water supply function of that head or more, water can be supplied to the highest part of the piping exceeding 7m. Therefore, as soon as the water that has passed through the highest part reaches the discharge port at the downstream end, the siphon action is activated and negative pressure is generated in the siphon water supply hose, and the check valve of the siphon water intake port provided on the side of the main body of the water injection merging member is pushed by the water pressure of the water in the water storage section, pushing the check valve open and allowing water to flow inside the main body of the water injection merging member. In this case, the degree to which the check valve opens is not constant because the water supply device continues to operate, depending on the balance of the water pressure of the water supply device and the water pressure of the siphon water intake, but since the siphon water intake action is activated, the amount of water supplied is significantly increased by the water supply work using the water supply device and the siphon water supply work in combination. As a guideline for this amount of water increase, the water supply function curves provided by various submersible pump manufacturers show that, for example, in the case of the Tsurumi Manufacturing Co., Ltd. submersible pump KTZ43.7, when using a siphon and a submersible pump together to carry out water supply work at a site with a head of 10m, the water supply volume when using the submersible pump alone is 1.0m 3 / min, but when used in conjunction with the siphon effect, the maximum head is 10m - 7m (maximum head) = 3m, so the value for the water supply function with a head of 3m can be read from the graph as 1.4m. 3 / min, which means that one submersible pump can be operated to pump 1.4 times the amount of water. If the head is 7m or less when the siphon action is activated, the siphon flow will be automatically activated by the switching valve inside the water injection merging component when the water supply equipment is stopped. Also, if the head is 7m or more, the water supply work can be performed in combination with the siphon action by continuing to use the water supply equipment. As an example of water supply work using this siphon and water supply equipment in combination, in the trial calculation of the water supply work for construction work at a dam, if a 200mm diameter submersible pump was used alone, 23 submersible pumps would have to be operated for six months, but if the same 200mm siphon and submersible pump were used in combination, 13 pumps could be used to pump the same amount of water. The fuel costs of continuing to operate 23 submersible pumps and operating 13 pumps in combination with the siphon can be used to perform the water supply work of 23 submersible pumps, which significantly reduces fuel costs. In addition, by placing the water injection junction member underwater, the hose between the siphon intake port underwater and the water injection junction member, which was always necessary in the previous patented technology, is no longer necessary, and it is possible to configure a single pipe from the water injection junction member, which has a siphon intake port equipped with a check valve on the side of the main body connected to the water supply device, to the downstream discharge port. The water supply device is connected directly or via a water supply device connection member to the connecting part of the upstream opening of the water injection junction member, the siphon intake port equipped with a check valve on the side of the main body is covered with a water intake dustproof basket as necessary to make it a siphon intake part, and a siphon water supply pipe (hose) that supplies water injected by the water supply device or water sucked by the siphon is connected and extended to the connecting part, which is one opening on the downstream side of the water injection junction member, and it can be configured with a single water supply hose through the highest part of the piping to the downstream discharge port, which makes it possible to achieve cost reduction and simplification of installation work by omitting the materials for the water supply hose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] (First embodiment) Next, a siphon water supply device 100 using a water pouring and merging member according to the first embodiment will be described in detail with reference to the drawings. The siphon water supply device 100 according to the first embodiment is shown in FIG. 1. FIG. 2 is an enlarged view of part A in FIG. 1, and is a combination diagram of a siphon activation water supply member 14 arranged on the water storage section 1 side among various members constituting the siphon water supply device 100. The siphon activation water supply member 14 refers to a combination of members arranged in the water storage section 1 among members necessary for starting the siphon, and refers to a member selected from a water supply device 20, a water supply device connection member 12, a water pouring and merging member 30 having a siphon water intake port 11a, and a siphon water intake dustproof basket 15.

[0019] As shown in Fig. 1 and Fig. 2, the siphon water supply device 100 according to the first embodiment mainly includes a water supply device 20 such as a submersible pump for starting the siphon water supply device 100, a water supply device connection member 12 connected to the water supply device 20, a siphon water supply pipe 13 arranged on the downstream side, and a water injection merging member 30 having a siphon water intake port 11a for absorbing water from the water storage section 1 in the upstream area or high water area. In this embodiment, the water supply device 20, the water supply device connection member 12, and the water injection merging member 30 are arranged in the water storage section 1 in the high water level area, and these constitute a siphon start water supply member 14. A part of the siphon water supply pipe 13 is arranged in the water storage section 1, and the discharge port 13a of the siphon water supply pipe 13 is installed at a position lower than the water level 1a of the water storage section 1 so that the siphon action can be exerted.

[0020] 2, the water injection and merging member 30 is connected to the water supply device 20 at the upstream opening 35, which is the opening on the upstream side, directly or via the water supply device connecting member 12. Of the siphon water supply device 100, each member (siphon activation water supply member 14) disposed in the water storage section 1 is assembled and then used by immersing the entire member in water.

[0021] The pipe members used in the siphon water supply operation, such as the water supply device connection member 12 and the siphon water supply pipe 13, are made of hard hoses or pipe materials whose cross-sectional shape does not easily deform. Examples of hoses made of hard materials include what are commonly called suction hoses, hoses made of hard polyethylene or polyvinyl chloride, and steel pipes.

[0022] The water conveying device 20 is a pump with a water conveying function that is operated by electricity, and is attached to the tip of the water conveying device connection member 12. The water conveying device 20 can be turned on / off by a switch (not shown) on a distribution board to which the power source of a generator or a system is drawn.

[0023] As shown in FIG. 3, the water injection merging member 30 is made by processing one cylindrical member, and has an upstream opening 35 and a downstream opening 36 on the upstream side and downstream side, respectively. The water supply device 20 is attached to the upstream opening 35 directly or via the water supply device connection member 12. The downstream opening 36 is connected to the siphon water supply pipe 13. The ends of the respective openings (35, 36) of the water injection merging member 30 are provided with flanges 37, 38 having a connection function, and as shown in FIG. 2, the openings (35, 36) can be easily and firmly connected to the pipes using the flanges 37, 38. The pipe material of the water injection merging member 30 may be a cylinder with a circular cross section as shown in FIG. 3, or may be a square tube with a square cross section as shown in FIG. 6. The side surface of the water injection merging member 30 is provided with a siphon water intake port 11a that can absorb water from the water storage section 1. This siphon water intake port 11a is provided with a check valve 32. As shown in Fig. 4, the check valve 32 has a hinge structure that rotates inward of the water inlet / outlet member by being pushed by the water pressure of the reservoir when the water pressure inside the water inlet / outlet member becomes lower than the water pressure in the water reservoir, and can suck in water from the water reservoir 1, but prevents the sucked water from flowing back out into the water reservoir 1. The shape of the siphon intake 11a is circular, elliptical, polygonal, or a combination of these. The surface of the check valve 32 may be flat, curved, or a combination of these. Preferably, the check valve 32 is attached to the siphon intake 11a by a hinge or the like, using a cutout piece 33 that is generated when the side surface of the water inlet / outlet member 30 is cut out to provide the siphon intake 11a. The cut-out piece 33 generated when cutting out to provide siphon intake 11a naturally corresponds approximately to the shape of siphon intake 11a, so by attaching this as check valve 32 via hinge 11b, it is possible to obtain a check valve 32 of an appropriate size that matches the shape of the opening of siphon intake 11a. Note that check valve 32 does not have to be a reused piece cut out from a straight pipe, but may be a newly processed one.Furthermore, since the water injection and merging member 30 used in this embodiment is immersed in water, even if the welded parts are not completely airtight during production, the siphon action will not be affected at all because it will only suck in water rather than air through the weld gaps, allowing the siphon action to continue.

[0024] Also, the cylindrical member of the water injection and merging member 30 may be curved as shown in Fig. 7, and the check valve 32 may be provided in the curved portion. When the siphon action is activated, the position of the siphon water intake 11a faces the direction of the downstream flow, so the flow of water sucked by the siphon does not bend, and the amount of water supplied can be increased. For example, in a siphon water supply device with a diameter of 200 mm, with a suction side hose extension lift of 10 m, a discharge side hose extension of 50 m, a lift of 5 m, and a head difference of 5 m, if the number of bends in the suction side or discharge side hose is increased by one, the amount of water supplied will be increased by 0.05 m. 3 / min water supply capacity is reduced, so a piping structure that does not bend the water flow is effective.

[0025] Furthermore, as shown in Fig. 8, the water injection and merging member 30 may be provided with a check valve 32 protruding laterally from the main body of the water injection and merging member 30, and rotatably provided in a storage section 39 capable of storing the check valve 32 having a siphon water intake 11a at its tip. By providing the check valve 32 in this manner, even if the check valve 32 is rotated to an open state, it is possible to prevent the check valve 32 from narrowing a part or the whole of the internal water flow cross section of the main body. As a result, both the water intake action by the siphon action and the water supply function by the water supply device can be performed simultaneously, so that even if the head is 7m or more, by operating a water supply device having a water supply function to a head of 7m or more in combination, the siphon function can be used to supply water even in a piping with a head of 7m or more.

[0026] As shown in FIG. 5, a siphon water intake dustproof basket 15 may be provided at the portion having the siphon water intake port 11a so as to cover the siphon water intake port 11a.

[0027] 1, a siphon stopping air suction member 80 is provided at or near the highest part of siphon water supply pipe 13. By opening siphon stopping air suction member 80, air can be supplied into siphon water supply pipe 13. Therefore, when it is desired to stop water supply, air can be sucked in by opening the opening / closing part of siphon stopping air suction member 80, and water can be discharged from siphon water supply pipe 13, thereby stopping siphon water supply. In the siphon water supply device according to this embodiment, siphon start water supply member 14 is disposed inside water storage section 1, and therefore it is an important member as a device for stopping the siphon outside water storage section 1.

[0028] As described above, according to the siphon water supply device 100 of this embodiment, as shown in Fig. 12 showing a previously developed technology, two hoses, a submersible pump water supply hose 140 and a siphon water supply hose 150, were installed from the water where the water supply device 20 and the siphon water supply suction pipe 11 were installed to the water supply junction member 30 in two-way piping, whereas as shown in Fig. 1, a suction pipe is not required and a single piping can be used from the water. In addition, the siphon water supply members such as the water supply device 20, siphon water supply port 11a, water supply device connecting member 12, and water supply junction member 30 required for starting the siphon can be arranged in one place within the water storage section 1.

[0029] As shown in Fig. 9, an air backflow prevention member 60 made of a hose made of a flexible material may be provided at or near the discharge port 13a. If the discharge port 13a is made of a hard material, when the amount of water decreases due to the siphon action, a space is created above the discharge port 13a of the downstream siphon water supply pipe 13, and air may flow in from there, reach the highest part of the piping, and accumulate, causing the siphon action to stop. However, by providing an air backflow prevention member 60 made of a hose made of a flexible material, the cross section of the hose changes depending on the amount of water discharged from the discharge port 13a, and it is possible to prevent the creation of a space through which air can flow back.

[0030] In the siphon water supply device 100 according to the first embodiment, when the head is 7 m or less, when the water supply device 20 sucks in water, the water flows to the outlet 13a at the downstream end of the siphon water supply hose 10, and the siphon water supply hose 10 is filled with water and flows. If this state is confirmed, the water supply device 20 is stopped, and the siphon water supply hose 10 continues to flow down in a full water state, and the siphon action is started. In addition, when the head is 7 m or more, the head may be 20 m or more depending on the site conditions. In such a site condition, if the head exceeds 7 m, negative pressure is generated at the highest part of the piping by the siphon water supply action alone, and the water in the water supply pipe at the highest part of the piping tries to flow down by dividing into the downstream side and the upstream side due to their own weight, so a large negative pressure is generated at the highest part of the piping, and a cavity is generated due to the evaporation phenomenon of water, and the siphon stops. Therefore, when the water that is trying to flow upstream is pushed up to the highest part of the pipe by the water pressure from the water supply equipment, the cavity at the highest part of the pipe disappears and the water is connected to the inside of the water supply pipe, and the siphon water supply operation continues. In other words, at sites with a head of 7m or more, stopping the water supply operation from the water supply equipment creates a cavity at the highest part of the pipe and the siphon action stops, so the water supply operation from the water supply equipment is an essential siphon water supply operation. In terms of cost and environmental impact, the siphon water supply method, which keeps the water supply equipment running, seems to be no different from the conventional submersible pump method. However, this method of siphon water supply using a siphon and water supply equipment in combination has the following major advantages. According to estimates, at a site with a head of 18m, it is possible to achieve a flow rate of 1.0m per second. 3 At a site where discharge of 2.85 m is required, a Φ200mm submersible pump can deliver 2.85 m 3 / min, 22 pumps had to be operated 24 hours a day for six months, but the water discharge rate was 4.9 m / min when using a Φ200mm siphon and a Φ200mm submersible pump in combination. 3 / min, only 13 units will be required. The fuel required to operate the submersible pumps will be reduced by 889,200L (4,446 drums), which is equivalent to the fuel required for nine submersible pumps. In addition, the reduction in fuel consumption will reduce greenhouse gas emissions by 2,700kg of CO2. 2This has made it possible to reduce the occurrence of

[0031] Second embodiment Next, the siphon water supply device according to the second embodiment will be described with reference to the drawings. The siphon water supply device 100 according to the second embodiment is a storage frame type siphon water supply device 100 in which necessary members are assembled and fixed in a storage frame 90 as shown in FIG. 11. The storage frame type siphon water supply device 100 according to the second embodiment is mainly provided with a water supply device 20 such as a submersible pump for starting the siphon water supply device 100, a pipe consisting of a water supply device connection member 12 connected to the water supply device 20 and a siphon water supply pipe 13 arranged downstream, and a water injection merging member 30 connecting them, as shown in FIG. 10. The second embodiment differs from the first embodiment in that an installation method is adopted in which the water supply device connection member 12, the water supply device 20, and the siphon start water supply member 14 such as the water injection merging member 30 are assembled and fixed in the storage frame 90 and immersed in water to install them together.

[0032] In this embodiment, as shown in Figures 10 and 11, a siphon water supply pipe 13 is connected to the downstream opening 36 of the water injection junction member 30, and a water supply device 20 is connected to the upstream opening 35 via a water supply device connection member 12. These siphon-activated water supply members 14 are stored in a hanging storage framework 90, assembled and fixed, and the hanging storage framework 90 to which the siphon-activated water supply member 14 is fixed is hung and the entire hanging storage framework 90 is immersed in water to supply water.

[0033] As shown in Fig. 11, the hanging storage framework 90 includes a front hanging framework 91 formed in a substantially rectangular shape, a wall side shock-protection type hanging framework 92 that is placed on the wall side when hanging, and a connecting framework 93 that connects them at a predetermined interval. The size of the hanging storage framework 90 is preferably about 1500 cm wide x 800 cm deep x 2500 cm high. Of course, this size is not limited. The wall side shock-protection type hanging framework 92 is provided with a wire mesh (not shown) such as expanded metal or wire lath. The siphon water supply equipment 14 is fixed to the wire mesh using a fastening member 95 such as a wire or a metal cable tie. Furthermore, by attaching a lattice-shaped steel frame or a net-shaped expanded metal to all six surfaces of the box-shaped hanging storage framework 90, the net-like shape serves as an anchor for binding various siphon components when fixing them inside the hanging storage framework 90, and prevents the intake of dust during the water intake work of the water supply device and the siphon water intake part. Optionally, a hanging frame reinforcing member 96 may be installed to reinforce the wall-side impact protection type hanging framework 92. Also, the hanging storage framework 90 is provided with a hanging hook 97 used when hanging the hanging storage framework 90.

[0034] The siphon-activated water supply member 14 assembled, stored, and fixed in the hanging storage framework 90 as described above is immersed under the water surface using the hanging hook 97 of the storage framework 90 and the hanging wire 98A, as shown in Figures 10 and 11. First, the work base 3 is installed at the highest part 2 of the piping using the fixing anchor 4, and the foundation surface is constructed. Then, using a heavy machine such as a crane, the hanging hook 97 of the storage framework 90 is used to hang the vertical wall surface or the side of a wall surface close to a vertical surface to the water surface of the high water level area. At this time, by hanging the hanging frame reinforcing member 96 so that it faces the wall surface, even if the storage framework 90 hits the wall surface, the possibility of the hanging storage framework 90 being damaged by the hanging frame reinforcing member 96 hitting the wall surface first can be reduced. When the siphon water supply equipment is fixed to the expanded metal, by placing the suspension frame reinforcing member 96 on the ground so that the bottom surface is the bottom surface, a space is provided between the ground and the expanded metal, so that the tip of the fastening member 95 can be passed through the mesh of the expanded metal to the ground side and then folded back on the mesh in the adjacent area to the front side where the siphon components are bound. Also, in order to prevent the gravity of the storage frame 90 in which the siphon water supply equipment is stored from being applied to the siphon water supply pipe (hose) 11, as shown in Fig. 10, a siphon water supply pipe lifting wire 98B for lifting the siphon water supply pipe 13 is adjusted to the length of the siphon water supply pipe 13 or less by using a connecting metal fitting (e.g., a turnbuckle) 99 for the siphon water supply pipe 13 in addition to the storage frame hanging wire 98A that hangs the storage frame 90. In this way, even if water flows through siphon water supply pipe 13, the gravity of the water is not directly applied to siphon water supply pipe 13, thereby protecting siphon water supply pipe 13. The lengths of storage framework hanging wire 98A and siphon water supply pipe hoisting wire 98B, and the length of siphon water supply pipe 13 are adjusted by arranging storage framework 90, siphon water supply pipe 13, storage framework hanging wire 98A, and siphon water supply pipe hose hanging wire 98B side by side on flat ground and combining them to adjust the lengths.After that, a crane is used to hoist the storage framework suspending wire 98A and the upper end of the siphon water supply pipe hoisting wire 98B to a height completely clear of the work area, move them above the water surface of the water storage section, and gradually lower them so that the storage framework 90 is set at the desired position and water depth. After that, the upper ends of the storage framework suspending wire 98A and the siphon water supply pipe hoisting wire 98B are fixed to the work base 3, and the installation work of the siphon water supply device 100 is completed.
