Problems to be solved by the invention

[0004] However, a water-repellent material having a plurality of box shapes made of a resin molded product is used in the vertical and horizontal directions and in the height direction. This type of storage tank formed by assembling a water-absorbing material assembly and encapsulating the assembly with a water-impervious sheet or water-permeable sheet has the following problems. That is, first, there is a limit to stacking water-absorbing materials having a box shape in the height direction, and it is not possible to deal with large-scale waste. Secondly, all construction works are of the same quality, making it impossible to respond flexibly, such as construction according to usage conditions and site conditions. Third, the so-called economies of scale that reduce the material cost and construction cost per unit volume with the increase in size cannot be obtained. Fourthly, there was a problem that it was impossible or extremely difficult for people to enter and manage and inspect.

[0005] A first object of the present invention is a collection of storage tank pipes that can be extended relatively easily in the height direction, and that the storage tank can be enlarged relatively easily by extending the height. To provide a body.

A second object of the present invention is to provide a collection of storage tanks that can be flexibly adapted to the field conditions.

A third object of the present invention is to provide a collection of storage tanks that can reduce material costs and construction costs per unit volume.

A fourth object of the present invention is to provide an assembly of storage pipes that are relatively easy to manage and inspect.

Means for solving the problem

[0006] As shown in FIG. 11, the invention according to claim 1 is configured such that a plurality of rigid pipes 14 and a plurality of rigid pipes 14 which are erected straight with a predetermined interval W in the horizontal direction are connected to each other. This is an improvement of the pipe assembly 11 that includes pipe connection means 13 that are connected in parallel and is encapsulated in a sheet 12 to form the storage tank 10.

As shown in detail in FIG. 1, the characteristic structure is that a mounting hole 14a is formed on the outer periphery of the rigid pipe 14, and the noise coupling means 13 is arranged at a predetermined interval W and has a length L shorter than the predetermined interval W. The connecting pipe 15, the cylindrical portion 16 a provided at both ends of the connecting pipe 15, which can be inserted into the connecting pipe 15, and the flange portion 16 b which is formed continuously from the cylindrical portion 16 a and faces the edge of the connecting pipe 15, and the flange portion A central hole 1 having a short pipe portion 16c that is provided coaxially with the cylindrical portion 16a through 16b and can be inserted into the mounting hole 14a, and passes through the short pipe portion 16c, the flange portion 16b, and the cylindrical portion 16a. An adapter 16 having 6d formed therein, a connecting steel rod 17 having a length through which both ends can be inserted into the center holes 16d of the adapter 16 provided at both ends of the connecting nozzle 15 through the connecting pipe 15. Part 16c is provided inside the rigid pipe 14 inserted from the outside into the mounting hole 14a, and the end of the connecting steel rod 17 passed through the center hole 16d is drawn into the rigid pipe 14 and connected to the flange part 16b. Fixing means 17 a, 18, and 19 for fixing the two rigid pipes 14 to each other by attracting the two rigid pipes 14 adjacent to each other with the nozzle 15 interposed therebetween, and the short pipe portion of the flange portion 16 b 16c side end face is configured to be able to adhere to the outer surface of rigid pipe 14 around mounting hole 14a with short pipe part 16c inserted into mounting hole 14a, and flange part 16b thickness D and connecting pipe 15 length L Where the sum of is equal to the predetermined interval W A.

[0007] In the assembly of pipes for a storage tank described in claim 1, the rigid pipe 14 is formed without using a water-spilling material having a conventional box-like shape and a molded resin product. Use. The main feature is that the rigid pipe 14 is erected vertically at regular intervals, and the rigid pipe 14 is connected by a horizontal connecting pipe 15 corresponding to the beam to form a lattice-like three-dimensional structure. . Therefore, first, by increasing the length of the rigid pipe 14 itself, or by connecting a plurality of rigid pipes 14 in the longitudinal direction in units of 2 m or 4 m, the height of the aggregate of pipes obtained is increased. The thickness can be increased relatively easily. For this reason, the internal height of the storage tank obtained by increasing the height is also increased and the internal volume is increased, so that the resulting storage tank can be relatively easily enlarged.

Secondly, when this Neuve aggregate is buried in the ground and a storage tank is formed, the horizontal stress applied to the aggregate of pipes by earth pressure increases in proportion to the underground depth. However, in the Neuve assembly described in claim 1, the number of horizontally extending connecting pipes 15 connecting the rigid pipes 14 is increased in proportion to the depth of the ground, so that the proportionality to the depth is achieved. The increased stress can be absorbed by the increased number of connecting pipes 15, and the length of the rigid pipe 14 and the number of connecting pipes 15 can be changed relatively easily according to the site. It is possible to respond flexibly according to the situation.

[0008] Thirdly, in the pipe assembly described in claim 1, when the length of the rigid pipe 14 and the connecting pipe 15 is increased, the storage tank obtained is also enlarged. Self There will be no increase in body construction time. For this reason, material and construction costs per unit volume can be reduced as the size increases.

Fourthly, in the aggregate of pipes described in claim 1, the rigid pipe 14 is coupled by the coupling pipe 15. Therefore, if the length of the coupling pipe 15 is long, it is between the rigid pipe 14 and the rigid pipe 14. It is possible to make it easier to manage and inspect the assembly of pipes.

In the pipe assembly described in claim 1, the adapter 16 is provided at both ends of the connection pipe 15, and the flange 16b of the adapter 16 and the connection pipe 15 are interposed between the two stiffnesses. Although the pipe 14 is attracted and fixed to each other by the fixing means 17a, 18, 19, the flange portion 16b is configured to be in close contact with the outer surface of the rigid pipe 14. The connecting force between the rigid pipes 14 that cannot be tilted is increased, and it becomes possible to obtain the aggregate 11 of the storage pipes with little deformation as a whole.

[0009] The invention according to claim 2 is the invention according to claim 1, wherein the fixing means includes male threads 17a formed on both ends of the connecting steel rod 17, and short pipe portions 16c from the outside. 14a scissors are inserted into the end of the connecting steel rod 17 from the inside of the inserted rigid pipe 14 and contact the inner wall of the rigid pipe 14, and at the end of the connecting steel rod 17 into which the collar 18 is inserted. The inner thread of the rigid pipe 14 is also screwed into the male thread 17a, and the nut 19 is provided to pull the end of the connecting steel rod 17 into the rigid pipe 14 through the collar 18.

In the assembly of storage pipes described in claim 2, the flange of the adapter 16 can be obtained by a relatively simple operation in which the nuts 19 are respectively screwed into the male threads 17a at both ends of the connecting steel rod 17. The two rigid pipes 14 with the portion 16b and the connecting pipe 15 interposed therebetween can be fixed by being attracted to each other via the force roller 18.

[0010] The invention according to claim 3 is the invention according to claim 1 or 2, wherein the connection pipe 15 includes a pipe main body 15a into which the cylindrical portion 16a of the adapter 16 can be inserted at an end, and a pipe main body 15a. The spacer 15b is provided at one end or both ends, and the spacer 15b is configured to be fitted to the cylindrical portion 16a, and the edge of the Neuve main body 15a having the end portion fitted to the cylindrical portion 16a and the adapter. It is configured to be able to close the gap between the 16 flange parts 16b, and the thickness A of the spacer 16b is the cylindrical part 1 The sum of the length C of the pipe body 15a and the thickness of the spacer 16b (2 XA) forms the length L of the connecting noise 15 which is shorter than the length B of 6a.

In the assembly of storage tank pipes described in claim 3, since the connecting pipe 15 is constituted by the pipe body 15a and the spacer 15b that can be fitted to the cylindrical portion 16a, the end of the pipe body 15a When the cylindrical portion 16a is inserted until the flange portion 16b comes into contact with the edge thereof, the distance between the adapters 16 provided on both sides of the pipe body 15a is shortened by the thickness A of the spacer 15b. Therefore, as shown in FIG. 2 (a), in the short state, even if two adjacent rigid pipes 14 maintain a predetermined interval W, the short pipe portion 16c of one adapter 16 is connected to the same. The short pipe portion 16c of the other adapter 16 can be made to face the mounting hole 14a of the other rigid pipe 14 in a state where it is inserted into the mounting hole 14a of the other rigid pipe 14. Then, as shown in FIG. 2 (b), the short tube portion 16c of the other adapter 16 is inserted into the mounting hole 14a of the other rigid pipe 14, and as shown in FIG. If the spacer 15b is fitted into the cylindrical part 16a of the gap between the edge and the flange part 16b of the adapter 16 to close the gap, the length C of the pipe body 15a and the thickness of the spacer 16b The sum of A constitutes the length L of the connecting pipe 15, and the two rigid pipes 14 are connected by the pipe connecting means 13 that does not move the two rigid pipes 14 that keep the predetermined interval W. be able to.

The invention according to claim 4 is the invention according to any one of claims 1 to 3, and as shown in FIG. 4, the invention relates to one or both of the flange portion 16 b and the connecting pipe 15 of the adapter 16. Joint hook 23 configured to be able to stop, and two side posts 22 configured to follow two rigid pipes 14, 14 attached to joint hook 23 and fixed to each other by pipe connecting means 13 , 22 and multiple support steel rods 26 installed between the two side posts 22 and 22, and the support steel rods 26 attached to the multiple support steel rods 26 and blocking between the two side posts 22 and 22 The pressure plate 21 is configured so that the outer surface of the pressure plate 21 is flush with the outer surfaces of the two side posts 22 and 22 and the outer surface of the rigid pipe 14 is in contact with the extended surface. It is characterized by that.

In the assembly of storage tank pipes described in claim 4, by providing a plurality of pressure-resistant plates 21 around, the difference between the surrounding rigid pipe 14 and the pipe connecting means 13 can be reduced. Can be filled with 21. The pressure plate 21 has two outer surfaces. Since the outer surface of the rigid pipe 14 is flush with the outer surface of the side posts 22 and 22 and the outer surface of the rigid pipe 14 is in contact with the extended surface, it is an assembly of pipes with multiple pressure plates 21 around them. 11 has a rectangular shape as a whole, and this assembly 11 can be encapsulated with a sheet 12 to form a structure that is firmly attached to the inside, and an external force such as earth pressure is applied to the sheet 12. Can be prevented from being greatly deformed.

[0012] The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein, as shown in FIG. 9, four rigid pipes connected in a lattice form by pipe connecting means 13 A bracing plate 27 is installed between the upper and lower portions of each of the two rigid pipes 14 located on the 14 diagonal lines so that the upper or lower surface is flush with the upper or lower edge of the rigid pipe 14. It is characterized by that.

In the collection of storage tank noises according to claim 5, the upper or lower surface of the rigid pipe 14 is flush with the upper or lower edge of the rigid pipe 14 between the upper or lower portions. Since the bracing plate 27 is installed, the upper edge of the pipe assembly 11 including these is constituted by the upper edge of the rigid pipe 14 and the upper surface of the bracing plate, and the lower edge of the pipe assembly 11 including these is the rigid pipe. It consists of 14 lower edges and the underside of the brace. For this reason, the area which substantially comprises the upper surface and the lower surface of the Neuve aggregate can be increased, and thereby the stability of the pipe aggregate 11 can be further improved.

The invention's effect

[0013] In the assembly of pipes of the present invention, rigid pipes are erected vertically at regular intervals and connected by horizontal connecting pipes to form a lattice-like three-dimensional structure. Accordingly, it is possible to relatively easily increase the height of the aggregate of noise obtained by increasing the length of the rigid pipe itself or by connecting a plurality of rigid pipes in the longitudinal direction. For this reason, the storage tank obtained by increasing the height can be enlarged comparatively easily. In addition, it is possible to absorb the stress that increases in proportion to the depth by increasing the number of connecting pipes in proportion to the depth, making it possible to respond flexibly according to the field conditions. Furthermore, the larger the size, the lower the material cost per unit volume and the construction cost. If a person can enter between the rigid pipes, the management inspection of the pipe assembly can be made impossible. I'll do it. Also, adapters are provided at both ends of the connecting pipe, and both ends of the connecting pipe and the connecting steel rod passing through the adapter are pulled into the rigid pipe by fixing means, and the flange portion of the adapter and the connecting pipe are interposed. The two rigid pipes are attracted and fixed to each other, and the flange portion that directly contacts the outer surface of the rigid pipe is configured to be in close contact with the outer surface of the rigid pipe. As a result, the connecting force between the rigid pipes that cannot be tilted increases, and it becomes possible to obtain an aggregate of reservoir pipes that are less deformed as a whole.

[0014] Also, if the connecting pipe is composed of a pipe body and a spacer, when an adapter is inserted into the end of the pipe body, the distance between the adapters provided on both sides of the pipe body is equal to the thickness of the spacer. Becomes shorter. Therefore, in the short state, even if two adjacent rigid pipes are kept at a predetermined interval, one adapter is inserted into one rigid pipe and the other adapter is inserted into the other rigid pipe. Can be opposed to each other. Then, if the other adapter is inserted into the other rigid pipe and the gap between the edge of the Neuve body and the adapter is closed by the spacer, the sum of the length of the pipe body and the thickness of the spacer is obtained. The two rigid pipes can be connected by a pipe connecting means that does not move the two rigid pipes that constitute the length of the connecting pipe and maintain a predetermined interval.

If a plurality of pressure plates are provided around the pipe assembly, the step between the rigid pipe and the pipe connecting means around the pipe is filled with the pressure plates, and the outer surface of this pressure plate is the two sides. If it is configured so that the outer surface of the rigid pipe is in contact with the outer surface of the post and on the extended surface, the aggregate of pipes with a plurality of pressure-resistant plates around them will form a square shape as a whole. This makes it easy to encapsulate the assembly with a sheet, and prevents the sheet from being deformed when an external force such as earth pressure is applied.

[0015] Furthermore, the upper surface or the lower surface is between the upper end or the lower portion of each of the two rigid pipes located on the diagonal line of the four rigid pipes connected in a lattice pattern by the pipe connecting means. If the bracing plate is installed so as to be flush with the lower edge, it will be braced with the rigid pipe !, and the upper edge of the assembly of pipes including the plate will be braced with the upper edge of the rigid pipe! The lower edge of the Neuve assembly is composed of the lower edge of the rigid pipe and the lower surface of the brace. For this reason, it was obtained by encapsulating Neuve's assembly with a sheet. The load that can be loaded in the storage tank can be increased. In addition, the area constituting the upper surface and the lower surface of the Neuve assembly substantially increases, and the stability of the pipe assembly can be further improved.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, the best mode for carrying out the present invention will be described with reference to the drawings.

As shown in FIG. 11, the underground storage tank 10 in this embodiment is provided for the purpose of storing rainwater, and is formed by wrapping a pipe assembly 11 with a water shielding or permeable sheet 12. . The Neuve assembly 11 is formed by connecting a plurality of rigid pipes 14 to each other by Neuve connecting means 13, and the plurality of rigid pipes 14 are arranged in parallel with each other in a state of being oriented in the vertical direction. . The rigid pipe 14 in this embodiment is an extruded vinyl chloride pipe having a diameter of 200 to 800 mm and a length of 50 to 400 cm. If the diameter of the rigid pipe 14 is less than 200mm If the length is less than 50cm, the number of rigid pipes 14 is increased. ] Significantly increases the construction cost per unit volume when the storage tank 10 is formed. If the diameter of the rigid pipe 14 exceeds 800 mm or its length exceeds 400 cm, it becomes difficult to transport the rigid pipe 14.

FIG. 10 is a perspective view showing a corner portion of the pipe assembly 11. As shown in FIG. 10, a mounting hole 14 a is formed on the outer periphery of the rigid pipe 14. The mounting holes 14a in this embodiment are formed in the vicinity of both ends of the upper and lower portions of the rigid pipe 14 and in the central portion with an interval of 90 degrees in the circumferential direction. In addition, the rigid pipe 14 near the central mounting hole 14a is separately formed with a work hole 14b into which an operator's hand can be inserted. The plurality of rigid pipes 14 are arranged vertically and horizontally in a horizontal plane, and are set up vertically at a predetermined interval W in the horizontal direction, in this embodiment, with an interval W of 50-200 cm, and in this state, through the mounting holes 14a. The pipes are connected in parallel by the pipe connecting means 13. For this reason, the four connecting means 13 are fixed radially at every 90 degrees in the mounting holes 14a in each stage of the rigid pipe 14 located inside the pipe assembly 11 when viewed from above. On the other hand, two connecting means 13 are fixed to the mounting holes 14a in each step of the rigid pipe 14 at the corners of the pipe assembly 11 with an interval of 90 degrees as viewed from above, and the pipe assembly 1 The three connecting means 13 are fixed to the mounting holes 14a in each step of the rigid pipe 14 located in the outer periphery of 1 at intervals of 90 degrees as viewed from above.

As shown in FIG. 1, the pipe connecting means 13 includes a connecting pipe 15 disposed at a predetermined interval W between two rigid pipes 14 and 14 adjacent to each other, and both ends of the connecting pipe 15. It is equipped with an adapter 16 installed. The adapter 16 provided at both ends of the connecting pipe 15 is the same, and one of them will be described as a representative. As shown in the enlarged view of FIG. 1, this adapter 16 can be inserted into the connecting pipe 15. A cylindrical portion 16a and a flange portion 16b formed continuously from the cylindrical portion 16a and facing the edge of the connecting pipe 15 and a mounting hole 14a of the rigid pipe 14 provided coaxially with the cylindrical portion 16a via the flange portion 16b And a short pipe part 16c that can be inserted into the pipe. The adapter 16 is formed with a center hole 16d that penetrates the short pipe portion 16c, the flange portion 16b, and the cylindrical portion 16a, and the end face of the flange portion 16b on the short pipe portion 16c side faces the attachment hole 14a. In the inserted state, the mounting hole 14a is bent so that it can adhere to the outer surface of the rigid pipe 14 around it. Composed. The outer diameter of the flange portion 16b is the same as the outer diameter of the connecting pipe 15, and is larger than the mounting hole 14a. Further, the outer diameter of the cylindrical portion 16a is formed to be slightly smaller than the inner diameter of the connecting pipe 15, and the end of the connecting pipe 15 can be fitted with a slight gap in the cylindrical portion 16a. Further, the short pipe portion 16c is formed to be slightly smaller than the mounting hole 14a, and is configured to be inserted into the mounting hole 14a with a slight gap.

On the other hand, the connecting pipe 15 is composed of a pipe body 15a into which the cylindrical part 16a of the adapter 16 can be inserted at the end, and a spacer 15b provided at one or both ends of the pipe body 15a. The pipe body 15a is an extruded PVC pipe with a diameter of 40-300mm. When the diameter force of the pipe body 15a is less than 0mm, the strength of connecting the two rigid pipes 14, 14 adjacent to each other decreases, and when the diameter of the pipe body 15a exceeds 300mm, the rigidity when the storage tank 10 is formed This is because the balance between the pipe 14 and the connecting pipe 15 is deteriorated, causing problems in workability and economy. The spacer 15b is configured to be fitted to the cylindrical portion 16a, and closes a gap between the end edge of the connecting pipe 15 fitted to the cylindrical portion 16a and the flange portion 16b. As shown in FIG. 3, the spacer 15b in this embodiment is a short cut of a vinyl chloride pipe that is the same as the pipe body 15a. Is formed. This spacer 15b opens the notch portion 15c by its elasticity, inserts the cylindrical portion 16a into the inside from the opened notch portion 15c, and closes the notch portion 15c by its elasticity to form the cylindrical portion 16a. It is configured so that it can be fitted. The thickness A of the spacer 15b is shorter than the length B of the cylindrical portion 16a in the adapter 16, and the sum of the length C of the pipe body 15a and the thickness A of the spacer is the length of the connected pipe. L (Fig. 1) is now configured!

Returning to FIG. 1, the pipe connecting means 13 has a length that allows the both ends to pass through the center hole 16d of the adapter 16 that penetrates the connecting pipe 15 and is provided at both ends of the connecting pipe 15. A steel rod 17 and fixing means for fixing the two rigid pipes 14 adjacent to each other by drawing the end of the connecting steel rod 17 inside the rigid pipe 14 are provided. The fixing means in this embodiment includes male screws 17a formed at both ends of the connecting steel rod 17, collars 18 inserted respectively at both ends of the connecting steel rod 17, and the connecting steel rod 17 And nuts 19 screwed into male screws 17a at both ends of the nut. Communicating The steel rod 17 is a rod material with excellent corrosion resistance and stainless steel strength. Both ends of the center hole 16d of the adapter 16 have a cylindrical portion 16a inserted through both ends of the connecting pipe 15 and the connecting pipe 15. Each is cut into a length that can be inserted, and formed by forming male threads 17a at both ends thereof.

[0023] The collar 18 is formed in a U shape by bending both ends of the steel plate in the same direction with a gap wider than the outer diameter of the short pipe portion 16c, and the end of the connecting steel rod 17 is inserted in the center thereof. A through hole 18a is formed. When the end of the connecting steel rod 17 is inserted into the through hole 18a so that the rising portions at both ends face the inner wall of the rigid pipe 14 from the inside, the short pipe portion 16c of the adapter 16 is obtained. Is configured such that the rising portions on both sides thereof abut against the inner wall of the rigid pipe 14 inserted into the mounting hole 14a.

The nut 19 is screwed into the end of the connecting steel rod 17 inserted through the collar 18, and when the nut 19 presses the collar 18, the flange 16b of the adapter 16 and the connecting pipe 15 are interposed between them. The rigid pipes 14 at both ends of 15 will be attracted to each other through their collars 18. Therefore, by tightening the nut 19, the rigid pipes 14 at both ends of the connecting pipe 15 are pressed against the flange 16b of the adapter 16 so that both side forces are sandwiched between the flange 16b of the adapter 16 and the connecting pipe 15 and fixed to each other. Is done. The sum of the thickness D of the flange portion 16b and the thickness L of the connecting pipe 15 is configured to be equal to the predetermined interval W.

Returning to FIG. 10, a plurality of pressure-resistant plates 21 for absorbing earth pressure are provided around the pipe assembly 11. The pressure plate 21 is provided between side posts 22 provided along two adjacent rigid pipes 14 and 14, and the side posts 22 are disposed around the pipe assembly 11 via joint hooks 23. It is attached to connecting means 13 for connecting the rigid pipe 14.

A plurality of bridges will be installed. The support steel rod 26 is a rod made of stainless steel having excellent corrosion resistance. By inserting both ends into the steel rod hole 22d (Fig. 4) formed in the side post 22, the two side posts 22 It is erected between.

As shown in FIG. 10, a pair of bracing plates 27 are provided on the upper and lower portions of the four rigid pipes 14 connected in a lattice pattern by the pipe connecting means 13 (FIG. Only the crossing plate is shown.) O As shown in Fig. 9, this bracing plate 27 has a notch 27a with a width equal to its thickness in the width direction in the center to half the depth, and two bracing plates 27 are prepared. Shi A pair of bracing plates 27 combined in a cross shape are formed by combining the cuts 27a with each other. The pair of bracing plates 27 are installed between the two rigid pipes 14 and 14 located on the diagonal lines of the four rigid pipes 14 connected in a lattice pattern by the pipe connecting means 13.

The end of the bracing plate 27 is fixed to the upper part or the lower part of the rigid pipe 14 via a fixture 28. Specifically, using a pair of bracing plates 27 provided at the top of the four rigid pipes 14 in FIG. 9, two locking holes 14c are formed in the lead straight direction at the top or bottom of the rigid pipe 14.

The

Next, a procedure for forming a storage tank using the Neuve assembly of the present invention will be described.

As shown in FIG. 11, the pipe assembly 11 of the present invention is assembled after excavating a place where the underground storage tank 10 is to be formed and disposing the water shielding or water permeable sheet 12. Specifically, in order to form the underground storage tank 10, a place where the underground storage tank 10 is to be formed is excavated according to the required depth and shape, and a water-impervious or permeable sheet 12 is provided at the lowermost part of the center. Deploy . Thereafter, a base plate 10a made of a synthetic resin plate in this embodiment is laid on the central portion of the water shielding or water permeable sheet 12, and a pipe assembly 11 is formed on the base plate 10a. At this time, since the pipe assembly 11 is obtained by connecting the rigid pipes 14 to each other by the connecting means 13 at a predetermined interval W in the horizontal direction, the rigidity pipe used is compared with the case where the rigid pipes 14 are closely attached. The amount of the pipe 14 can be reduced, and the unit price can be prevented from being pushed up due to the increase in the usage amount. The pipe connecting means 13 includes a connecting pipe 15 and an adapter 16, and the adapter 16 is attached to both ends of the connecting pipe 15. The nuts are respectively screwed into the male threads 17a at both ends of the connecting steel rod 17, and the two rigid pipes 14 are connected to each other via the collar 18 with the flange 16b of the adapter 16 and the connecting pipe 15 interposed therebetween. Attract and fix. Since the flange portion 16 b is configured to be in close contact with the outer surface of the rigid pipe 14, the adapter 16 does not tilt with the connecting pipe 15 together with the rigid pipe 14. As a result, it is possible to obtain a storage pipe aggregate 11 with less deformation as a whole.

[0029] Here, since the connecting pipe 15 is composed of the pipe body 15a and the spacer 15b that can be fitted to the cylindrical portion 16a, a flange is formed at the end of the pipe body 15a as shown in detail in FIG. When the cylindrical portion 16a is inserted until the portion 16b comes into contact with the edge thereof, the distance between the adapters 16 provided on both sides of the pipe body 15a is shortened only by the thickness A of the spacer 15b. Therefore, in the short state, even if the two rigid pipes 14 adjacent to each other maintain a predetermined interval W, the short pipe portion 16c of one adapter 16 is connected to one of the adapters 16 as shown in FIG. The short pipe portion 16c of the other adapter 16 can be opposed to the mounting hole 14a of the other rigid pipe 14 in a state where it is inserted into the attachment hole 14a of the rigid pipe 14. Then, as shown in FIG. 2 (b), the short pipe portion 16c of the other adapter 16 is inserted into the mounting hole 14a of the other rigid pipe 14, and as shown in FIG. If the spacer 15b is fitted into the cylindrical portion 16a of the gap between the end edge and the flange portion 16b of the adapter 16 to close the gap, the length C of the noise body 15a and the spacer 16b The sum of the thickness A constitutes the length L of the connecting pipe 15, and the two rigid pipes 14 are connected by the pipe connecting means 13 without moving the two rigid pipes 14 that keep the predetermined interval W. Can be made. For this reason, the aggregate 11 of pipes for a storage tank with little deformation as a whole can be obtained relatively easily.

[0030] Further, the pipe 11 for a storage tank according to the present invention is such that the upper surface or the lower surface is flush with the upper edge or the lower edge of the rigid pipe 14 between the upper part or the lower part of the rigid pipe 14. Since the bracing plate 27 (Fig. 9) is installed, the upper edge of the pipe assembly 11 including them is composed of the upper edge of the rigid pipe 14 and the upper surface of the plate 27, and the pipe assembly 11 including these The lower edge is constituted by the lower edge of the rigid pipe 14 and the lower surface of the bracing plate 27. For this reason, the area which substantially constitutes the upper surface and the lower surface of the pipe assembly 11 is increased, and the stability of the Neuve assembly 11 can be further improved. In addition, the presence of the brace 27 As a result, the pipe assembly 11 becomes a strong structure, and when external forces such as earth pressure are applied to the obtained storage tank, the pipe assembly 11 is prevented from being greatly deformed. That's right.

The assembled Neuve assembly 11 is encased in a water-permeable or water-permeable sheet 12. Here, in the collection 11 of storage tanks according to the present invention, since a plurality of pressure plates 21 are provided around, the step between the rigid pipe 14 and the pipe connecting means 13 around the pressure plate 21 is provided. Can be filled with 21. The outer surface of the pressure plate 21 is flush with the outer surfaces of the two side posts 22 and 22, and the outer surface of the rigid pipe 14 is in contact with the extended surface. The pipe assembly 11 provided with a plurality of pressure plates 21 has a rectangular shape as a whole, and the work of encapsulating the assembly 11 with the sheet 12 is facilitated, and the external tank has a large amount of stress and little deformation. Can be formed. The raised end of the water-permeable or permeable sheet 12 enclosing the pipe assembly 11 is placed on the upper side of the Neuve assembly 11 after surrounding the pipe assembly 11. As a result, the Neuve aggregate 11 is wrapped by the water-impervious or water-permeable sheet 12, and the storage tank 10 is formed. At this time, the deformation of the entire Neuve assembly 11 due to the inclination of the pipe connecting means 13 is avoided, and the workability when the obtained assembly 11 of pipes is encapsulated with the sheet 12 is Improves than before.

[0031] The storage tank 10 made in this way is connected to the intake pipe 10d, the vent pipe 10b, the overflow pipe 10c and the drain pipe 25a, and the upper ends of the intake pipe 10d, the vent pipe 10b and the drain pipe 25a are connected to each other. Reservoir 10 is backfilled as it appears on the surface. The upper end of the intake pipe 10d is connected to a rainwater collecting groove 10e etc. on the ground surface after that, and the rainwater collected in the groove 10e etc. is configured to flow into the storage tank 10. The vent pipe 10b is configured to release internal air to the outside of the ground or to allow air outside the ground to flow into the storage tank 10 when water flows from the intake pipe 10d or when water is drained by the drainage means 25 described later. . The overflow pipe 10c is configured to guide the surplus water from the storage tank 10 to the outside of the ground or to another storage tank or the like when the water inflow exceeds the internal volume of the storage tank 10.

[0032] In addition, a drainage means 25 capable of taking water stored in the storage tank 10 is provided on the surface above the backfilled storage tank 10 and located at the upper end of the drainage pipe 25a. Drainage means 25 is a drainage pipe 25a whose lower end penetrates the water-impervious or permeable sheet 12 and reaches the lower part of the storage tank 10, and a drainage pump that is provided on the ground and that the upper end force of the drainage pipe 25a can also suck water inside the storage tank 10. 25b. The drainage means 25 is configured such that the water in the storage tank 10 can be extracted from the discharge pipe 25c by discharging the water from the discharge pipe 25c by sucking the water in the storage tank 10 through the drain pipe 25a by the drain pump 25b. Is done.

In the underground storage tank 10 configured in this way, rainwater falling on the ground surface is collected in the rainwater collecting groove 10e and flows into the storage tank 10 through the intake pipe 10d, and this storage tank 10 flows into the interior. The rainwater is stored. The inflowing rainwater initially enters the inside of one of the rigid pipes 14, and then the rainwater also flows into the other rigid pipe 14, and the rainwater is effectively stored in the space surrounded by the water shielding or permeable sheet 12. The In this case, the proportion of the space occupied by the rigid pipe 14 is less than that of the conventional one in which a water-absorbing material made of sand, gravel, crushed stone, etc. is wrapped in a water shielding or permeable sheet. Tank 10 has more rainwater storage than the conventional one. In addition, if the rigid pipe 14 is made by processing a relatively inexpensive salty vinyl resin made in large quantities by extrusion molding, it will be compared with a stagnant material formed using an expensive mold. It is inexpensive and the unit price of underground storage tank 10 is not pushed up. In addition, if recycled products such as recycled noise are used as the rigid pipe 14 and the connecting pipe 15, it will open the way for pollution prevention and effective use of resources.

Industrial applicability

By increasing the connecting force between the rigid pipes, it is possible to obtain a collection of pipes for storage tanks with little deformation as a whole. A storage tank capable of storing rainwater can be obtained.
