Furthermore, the height of the horizontal storage tank 11 is set to 300-700 mm, Preferably it is 400-600 mm. The reason for setting the height of the horizontal storage tank 11 within the range of 300 to 700 mm is that if it is less than 300 mm, when the three vertical storage tanks 12 are erected on the horizontal storage tank 11, each vertical The storage tank 12 inclines irregularly in various directions, and if it exceeds 700 mm, the excavation workability on the ground 14 will deteriorate.

On the other hand, on the upper wall 11a of the horizontal storage tank 11, three positioning holes 11b through which the three vertical storage tanks 12 can be inserted are respectively formed at intervals in the longitudinal direction. In addition, on the upper surface of the lower wall 11c of the horizontal storage tank 11, three positioning short pipes 11d are respectively fixed with the center of the hole consistent with the above-mentioned three positioning holes 11b and capable of being inserted into the vertical storage tank 12. When the lower part of the vertical storage tank 12 is inserted into the short positioning pipe 11d through the positioning hole 11b, the gap between the positioning hole 11b and the outer peripheral surface of the vertical storage tank 12 is closed by the sealing member 13. As shown in detail in FIG. 1, the sealing member 13 has: a fitting short tube 13a fixed on the upper wall 11a of the horizontal storage tank 11 so as to surround the positioning hole 11b; The annular filler 13b made of synthetic rubber with an inverted U-shaped cross section is formed longer and larger in diameter than the short fitting pipe 13a, and is fixed so as to surround the outer peripheral surface of the short fitting pipe 13a.

That is, the base end of the inflow pipe 17 is connected to the drainage channel, and the top end of the inflow pipe 17 is connected to the upper surface of the vertical storage tank 12 on the right side. On the upper wall 11a of the horizontal storage tank 11, the base end of the water supply pipe 18 extends to the vicinity of the lower wall 11c of the horizontal storage tank 11 and is inserted, and the top end of the water supply pipe 18 extends into the horizontal storage tank 11 and The utilization destination (the utilization side, utilization object) of the rainwater 16 in the vertical storage tank 12. In addition, an electric pump 19 is provided in the middle of the water supply pipe 18 , and the electric pump 19 is installed on the floor 14 via a stand 20 . Moreover, the base end of the water supply short pipe 21 is connected to the outer peripheral surface of the center part of the left vertical storage tank 12 among the three vertical storage tanks 12. As shown in FIG. A faucet 22 for opening and closing the short water supply pipe 21 is connected to the tip of the short water supply pipe 21 ( FIGS. 1 and 2 ).

On the other hand, the upper parts of the adjacent vertical storage tanks 12 are communicated with each other through the upper communication pipe 23 .

The top of the vertical storage tank 12 is communicated and connected by the upper connecting pipe 23 on the left side. In addition, a discharge pipe is connected to the upper portion of any one of the three vertical storage tanks 12 (in this embodiment, the upper portion of the right vertical storage tank 12 among the three vertical storage tanks 12). 24 base end. The tip of the drain pipe 24 is configured to face a sewer, a river, or the like (not shown). The structure is such that the air stagnated in the upper part of each vertical storage tank 12 is discharged to the outside of the vertical storage tank 12 through the upper connecting pipe 23 and the discharge pipe 24, and the rainwater 16 overflowing from each vertical storage tank 12 is also passed through. The upper communication pipe 23 and the discharge pipe 24 discharge to the outside of the vertical storage tank 12 .

Furthermore, a rigid net 26 is spanned over all of the outer peripheries protruding from the ground among the three vertical storage tanks 12 ( FIG. 2 and FIG. 3 ). That is, it is configured so that the peripheries protruding to the ground among the three vertical storage tanks 12 are all surrounded by the rigid net 26 . Examples of the rigid net 26 include: nets formed by weaving metal wires such as stainless steel into a mesh shape (grid shape), nets formed by weaving metal wires covered with synthetic resin into a mesh shape, hard A net formed by weaving synthetic resin wires into a grid. In addition, the rigid net may be erected on a part of the outer circumference protruding to the ground among the three vertical storage tanks instead of all the outer circumferences of the three vertical storage tanks. Specifically, a flat plate-shaped rigid net may be erected along the common tangential direction of the outer peripheries protruding to the ground among the three vertical storage tanks.

A method of assembling the rainwater storage device 10 configured in this way will be described. At first each component such as horizontal storage tank 11, three vertical storage tanks 12 is made respectively in factory. Next, the rainwater storage device 10 is transported from the factory to the installation site in a component state without assembling. At this time, each member is relatively compact (small), so it can be transported by a small truck without using a large truck. After arriving at the installation site, the ground 14 is excavated into a cuboid shape with a predetermined depth, the bottom surface of the excavated part is compacted with gravel and sand, and then the horizontal storage tank 11 is inserted into the excavated part. Next, insert the lower part of the vertical storage tank 12 into the positioning hole 11b of the horizontal storage tank 11, then insert the positioning short tube 11d, and set up three vertical storage tanks in the horizontal storage tank 11 12. Then, the gap between the positioning hole 11 b of the horizontal storage tank 11 and the outer peripheral surface of the vertical storage tank 12 is blocked by the sealing member 13 . Specifically, the annular packing 13b is fitted on the short pipe 13a for fitting, and then surrounded by the inner peripheral surface of the short pipe 13c for suppression, the outer peripheral surface of the vertical storage tank 12, and the annular packing 13b. Fill the sealing material 13d in the space. In addition, an electric pump 19 is set on the stand 20, and the suction port of the electric pump 19 is communicated with the top of the horizontal storage tank 11 through the water supply pipe 18, and the discharge port of the electric pump 19 is connected to the rainwater 16 through the water supply pipe 18. Utilize the destination to communicate and connect, and then the excavated sand and soil are filled back into the gap between the excavated portion and the horizontal storage tank 11 , and on the top of the horizontal storage tank 11 . Thus, all of the horizontal storage tank 11 and the lower parts of the three vertical storage tanks 12 are buried in the ground, and the upper parts of the three vertical storage tanks 12 protrude from the center to the ground.

In the installation operation described above, the positioning operation of each vertical storage tank 12 becomes easy, so three vertical storage tanks 12 can be easily installed. In addition, each vertical storage tank 12 is all extended in a direction perpendicular to the upper wall 11a and the lower wall 11c of the horizontal storage tank 11, so the horizontal storage tank 11 is defined by its upper wall 11a and lower wall 11c. Since it is buried in the ground horizontally, all the vertical storage tanks 12 protrude to the ground while extending in the vertical direction. As a result, the appearance of the three vertical storage tanks 12 is not affected. In addition, the length of the vertical storage tank 12 buried in the ground is set at 25% to 40%, preferably 30% to 35%. For example, when the total length of the vertical storage tank 12 is 3 m, the length of the vertical storage tank 12 buried in the ground is preferably about 1 m. The length of the vertical storage tank 12 buried in the ground is limited to 25 to 40%, because if it is less than 25%, the standing stability of the vertical storage tank 12 will be damaged, and if it exceeds 40%, the ground will be damaged. Digging workability deteriorates.

Next, the adjacent vertical storage tanks 12 among the three vertical storage tanks 12 are respectively communicated and connected through the upper connecting pipe 23 . At this time, the intervals between the three vertical storage tanks 12 are kept constant, so the upper parts of the adjacent vertical storage tanks 12 can be relatively easily connected through the upper communicating pipes 23 of the same length. Then, the rigid net 26 was erected on the entire outer periphery protruding to the ground in the three vertical storage tanks 12 . Specifically, the rigid net 26 is formed into a substantially elliptical cylindrical shape, and the rigid net 26 is fitted with gaps in the three vertical storage tanks 12 , and then the rigid net 26 is fixed to the vertical storage tank 12 . The vines such as roses are climbed and planted on the rigid net 26 . Thereby, the appearance around the vertical storage tank 12 can be improved, and the global environment can be improved. Furthermore, the upper side of the vertical storage tank 12 on the right is connected with the inflow pipe 17, the upper part of the vertical storage tank 12 on the left side is connected with the discharge pipe 24, and the vertical storage tank 12 on the left side is connected up and down. The center of the direction is communicated with a water tap 22 via a short water supply pipe 21 . The rainwater storage device 10 can be installed by such a relatively simple operation.

In addition, in this embodiment, the rainwater storage device is transported in parts and assembled at the installation site, but if the rainwater storage device is relatively small, the rainwater storage device can also be assembled in the factory, and then the assembled The rainwater storage device is transported to the installation site. In this case, the installation work time of the on-site rainwater storage device can be shortened.

The operation of the rainwater storage device 10 installed in this way will be described. When it rains, the rainwater 16 that falls to the eaves of buildings such as houses and buildings, and the roof flows into the vertical storage tank 12 on the right side through the drainage channel and the inflow pipe 17 . The rainwater 16 is first stored in the lower part of the horizontal storage tank 11 and the three vertical storage tanks 12, and when more rainwater 16 flows in, it is stored in the three vertical storage tanks protruding upward from the horizontal storage tank 11. Type storage tank 12. At this time, the air in the three vertical storage tanks 12 is discharged to the outside of the vertical storage tanks 12 through the upper communication pipe 23 and the discharge pipe 24 . When spraying the rainwater 16 stored in the rainwater storage device 10 to the trees in the garden, etc., the electric pump 19 is operated. As a result, the rainwater 16 in the horizontal storage tank 11 is pressurized and sent to the utilization destination through the water supply pipe 18, so the rainwater 16 can be dispersed to trees and the like. On the other hand, when the rainwater 16 in the rainwater storage device 10 is drawn into the bucket, the short water supply pipe 21 is opened by operating the faucet 22 . The rainwater 16 positioned at the top of the short water supply pipe 21 flows out from the water tap 22 among the rainwater 16 in the three vertical storage tanks 12, so the rainwater 16 can be received by the bucket. In addition, when the rainfall is heavy, the rainwater 16 overflowing from the three vertical storage tanks 12 is discharged to the sewers, rivers, etc. through the upper connecting pipe 23 and the discharge pipe 24 .

In the installation work described above, the positioning work of each vertical storage tank 12 becomes easy, so four vertical storage tanks 12 can be easily installed. In addition, each vertical storage tank 12 is all extended along the right angle direction with respect to the upper wall 11a and the lower wall 11c of the horizontal storage tank 51, so each horizontal storage tank 51 is separated by its upper wall 51a and lower wall 51c. By being buried horizontally in the ground, all the vertical storage tanks 12 protrude toward the ground while extending in the vertical direction. As a result, the appearance of the four vertical storage tanks 12 is not impaired. In addition, even if the arrangement interval of the two horizontal storage tanks 51 changes slightly, the change can be absorbed by the expansion and contraction of the lower flexible pipe 61 and the upper flexible pipe 62, so that the assembly workability of the rainwater storage device 50 at the installation site can be improved. .

Next, two vertical storage tanks 12 are connected to each horizontal storage tank 51 through the upper connecting pipe 23 . At this time, in each horizontal storage tank 51, the interval between the two vertical storage tanks 12 is kept constant, so the length of the upper communication pipe 23 used in each horizontal storage tank 51 can be set as Likewise, time and labor for adjusting the length of the upper communication pipe 23 at the installation site can be saved. In addition, the upper part of the vertical storage tank 12 on the right side of the two vertical storage tanks 12 erected on the horizontal storage tank 51 on the left side and the horizontal storage tank 12 on the right side are connected by the upper flexible pipe 62. The upper part of the vertical storage tank 12 on the left side in the two vertical storage tanks 12 on the vertical storage tank 51 is communicated and connected. Then, a rigid net 66 is erected over the entire outer periphery protruding to the ground in the four vertical storage tanks 12 . Specifically, the rigid net 66 is formed into an approximately elliptical cylindrical shape, and the rigid net 66 is fitted with gaps in the four vertical storage tanks 12 , and then the rigid net 66 is fixed to the vertical storage tank 12 . Furthermore, among the two vertical storage tanks 12 erected on the horizontal storage tank 51 on the right side, the upper side of the vertical storage tank 12 on the right is communicated with the inflow pipe 17, and on the vertical storage tank 51 on the right side, The vertical center of the type storage tank 12 is communicated with a faucet 22 via a short water supply pipe 21 . In addition, among the two vertical storage tanks 12 erected on the left horizontal storage tank 51, the upper part of the left vertical storage tank 12 is communicated with the discharge pipe 24, and the vertical storage tank 51 on the left side is connected to the discharge pipe 24. The vertical center of the type storage tank 12 is communicated with a faucet 22 via a short water supply pipe 21 . The rainwater storage device 10 can be installed by such a relatively simple operation. The assembly method other than the above is substantially the same as the assembly method of the first embodiment, so repeated description will be omitted.

In addition, in this embodiment, the rainwater storage device is transported in a component state and assembled at the installation site, but if the rainwater storage device is relatively small, the two storage units of the rainwater storage device may be assembled in a factory, Then, the assembled two storage units are transported to the installation site together with other components, and the two storage units are connected through the lower flexible tube and the upper flexible tube at the installation site. In this case, the installation work time of the on-site rainwater storage device can be shortened.

The operation of the rainwater storage device 50 installed in this way will be described. When it rains, the rainwater 16 that falls to the eaves of buildings such as houses and buildings, and the roof flows into two vertical storage tanks erected on the horizontal storage tank 51 on the right side through the drainage channel and the inflow pipe 17. The vertical storage tank 12 on the right side in 12. The rainwater 16 is first stored in the lower parts of the two horizontal storage tanks 51 and the four vertical storage tanks 12, and when more rainwater 16 flows in, it is stored in the area protruding upward from the two horizontal storage tanks 51. In the 4 vertical storage tanks 12. At this time, the air in the four vertical storage tanks 12 is discharged to the outside of the vertical storage tanks 12 through the upper communication pipe 23 , the upper flexible pipe 62 and the discharge pipe 24 . When spraying the rainwater 16 stored in the rainwater storage device 10 to the trees in the garden, etc., the electric pump 19 is operated. As a result, the rainwater 16 in the horizontal storage tank 51 is pressurized and transported to the utilization destination through the water supply pipe 18, so that the rainwater 16 can be dispersed to trees and the like. On the other hand, when the rainwater 16 in the rainwater storage device 50 is drawn into the bucket, the short water supply pipe 21 is opened by operating the faucet 22 . The rainwater 16 above the short water supply pipe 21 flows out from the water tap 22 among the rainwater 16 in the four vertical storage tanks 12, so the rainwater 16 can be received by the bucket. In addition, when the rainfall is heavy, the rainwater 16 overflowing from the four vertical storage tanks 12 is discharged to the sewer, river, etc. through the upper connecting pipe 23 and the discharge pipe 24 . Operations other than those described above are substantially the same as those of the first embodiment, and thus redundant descriptions will be omitted.

In addition, in the first embodiment, three vertical storage tanks are vertically installed in one horizontal storage tank, and in the second embodiment, two vertical storage tanks are vertically installed in one horizontal storage tank. tank, but it is also possible to set up 4 or more vertical storage tanks in one horizontal storage tank. In addition, in the first embodiment, a single horizontal storage tank was exemplified, and in the second embodiment, two horizontal storage tanks connected to each other were exemplified, but three connected to each other may also be used. Or more than 4 horizontal storage tanks, the horizontal storage tank with 2 vertical storage tanks can also be connected with the horizontal storage tank with 3 vertical storage tanks.

In addition, in the first embodiment, the upper parts of the adjacent vertical storage tanks are communicated and connected through the upper communicating pipes, but it is also possible to not use the upper communicating pipes, and to provide exhaust holes or Connect the exhaust pipe. Furthermore, in the second embodiment, in each horizontal storage tank, the upper part of the adjacent vertical storage tank is communicated and connected through the upper connecting pipe, and the upper part of the adjacent horizontal storage tank is connected through the upper flexible pipe. The tops of the adjacent vertical storage tanks are communicated and connected, but the upper connecting pipe and the upper flexible pipe may not be used, and vent holes or exhaust pipes are arranged on the top of each vertical storage tank.
