(First embodiment)

EMBODIMENT OF THE INVENTION The 1st Embodiment of this invention is described in detail with reference to drawings. 1-3 show the connecting jig 1, the horizontal member 2, and the pipe-shaped vertical member 3 used as an assembly member for rainwater storage structures. That is, Fig. 1A shows the planar structure of the connecting jig 1, and Fig. 1B shows the I-I cross-sectional structure. Fig. 2A shows the left side structure of the horizontal member 2, Fig. 2B shows the bottom side structure, and Fig. 2C shows the II-II cross-sectional structure. Fig. 3 (a) shows the front structure of the pipe-shaped longitudinal member 3, and Fig. 3 (b) shows the III-III cross-sectional structure. 4 and 5 show a combination of the connecting jig 1, the horizontal member 2, and the pipe-shaped vertical member 3 shown in FIGS. 1 to 3, and the rainwater storage in the form of a jungle gym that is a three-dimensional structure. The procedure for assembling the structural assembly A is shown, FIG. 4 shows the front structure of the part, and FIG. 5 shows the planar structure of the part.

The connecting jig 1 is made of resin and, as shown in FIG. 1, protrudes from the cylindrical portion 1a that can be externally inserted into the vertical member 3 and the four portions of the outer circumferential surface, and is joined to the end of the horizontal member 2. It has the protrusion part 1b which connects both. The protrusion 1b is provided with four through-holes 1c for receiving and engaging the end projections 2a of the horizontal member 2 described later. In addition, a slightly small diameter through-hole 1d is also formed in the cylindrical portion 1a to reduce the weight, and to move the rainwater downward to store the water.

The horizontal member 2 is made of resin, and as shown in FIG. 2, the end projections 2a inserted into and coupled to the through holes 1c of the connecting jig 1 are formed under both ends, and in the longitudinal direction. The reinforcing rib 2b is formed in two parts of the space | interval by leaving a predetermined space | interval. Of course, the number, position, shape, etc. of the reinforcing ribs 2b can be changed in various ways.

The pipe-shaped vertical member 3 is made of resin, and as shown in Figs. 3 (a) and 3 (b), it has a cylindrical shape with a predetermined length, and is inserted into the cylindrical portion 1a of the connecting jig 1. It is possible.

In order to form the rainwater storage structure assembly A constituting the three-dimensional structure in the jungle gym form, as shown in FIG. 4 and FIG. 5, the connecting jig is mounted on the upper end of each vertical pipe member 3 installed vertically. Combine and install (1). Thereafter, the horizontal member 2 is provided in each of the through holes 1c of the two connecting jigs 1 adjacent to each other inside of each of the connecting jigs 1 mounted on the two pipe-like vertical members 3. By inserting and joining the end projection 2a of), the pipe-shaped vertical member 3 and the horizontal member 2 are connected, and this is repeated.

Next, the construction example which uses the rainwater storage structure granulated body A which assembled the rainwater storage structure assembly member which concerns on a present Example for a rainwater storage structure is demonstrated.

As shown in Fig. 6, a recess (pit) of about 1 to 5 m is excavated and formed on the ground, side grooves 7 are formed around the pit, and crushed stone and sand are laid on the bottom of the pit. It is leveled and the base B is formed. After laying the order sheet 4 which is an order material on the surface of the said base, as shown in FIG. 4, FIG. 5 from each pipe-type longitudinal member 3 and the connection jig 2 made of resin. Similarly, the rainwater storage structure assembly A of the jungle load type according to the pit content is constituted. When the pit contents are large, the rainwater storage structure granulated material A may be assembled in the pit, or after the rainwater storage structure granulated product A is assembled outside the pit, the pit may be inserted into the pit. It is preferable that the granulated material A for rainwater storage structures assembled in this way is fastened and fixed with a belt made of resin or metal. In addition, a rectangular panel may be sandwiched between the pipes on the side outer periphery to ensure flatness at the side outer periphery and to increase the strength.

In the side surface part C of the rainwater storage structure granulated material A, it is buried and returned as needed, and the piping 8 connected so that a rainwater can flow in a pit from the side groove 7 is provided. Moreover, the order sheet 5 is coated on the upper surface, and the covering 6 of about 0.5 to 1 m is performed from the said order sheet 5. These, the upper-order sheet 5 and the cover 6 form a coating layer. In addition, instead of covering the order sheet 5 on the upper surface of the granulated water for rainwater storage structure A, the water-permeable sheet may be coated to allow rainwater to penetrate. As for the side groove 7, the bottom part is deepened so that the airflow 9 may be formed in the bottom part.

It is preferable that the granulated material for rainwater storage structures A which is a three-dimensional structure has a compressive strength of at least 108 kN / m ² or more. In this way, even if a cover ² m (load: about 36 kN / m ² ) is applied to the top, it has sufficient strength three times or more of the earth pressure. Specifically, when using a horizontal member having a length of about 50 cm, a pipe-shaped member having a compressive strength of at least 27 kN / piece at 4 pieces / m ² is used, and when a horizontal member having a length of about 40 cm is used, 6 Use pipe-like members with a compressive strength of at least about 17.28 kN / piece at 25 pieces / m ² .

By doing in this way, rainwater can be stored once and used for various uses, such as spray water, washing water, emergency water, such as a garden, or it can be provided with the adjustment function so that a large quantity of rainwater may be discharged gradually. In addition, since the curing period and the like are unnecessary as compared with the case of being made of concrete, the construction speed of the rainwater storage structure can be made significantly faster.

Although the example which comprised the pipe-shaped member 3 so that internal coupling was possible to the cylindrical part 1a of the connection jig 1 was shown, the outer diameter of the cylindrical part 1a of the connection jig 1 was made small, and the pipe-shaped member ( You may make it internally couple to 3).

In the above example, an example is shown in which the end projection 2a of the horizontal member 2 is cylindrical, and the through hole 1c of the connecting jig 1 for inserting and engaging the end projection 2a is circular. However, instead, the end projections 2a of the horizontal member 2 may be square, and the through holes 1c of the connecting jig 1 may also be square to allow the end projections 2a to be inserted therein. . In this way, the position of the horizontal member 2 and the connecting jig 1, that is, the position of the horizontal member 2 and the pipe-like member 3 is fixed, and both are combined to provide good handling during assembly. At the same time, it is preferable because it can resist deformation due to external force.

Polyethylene pipes having an outer diameter of about 60 mm, a thickness of about 5.5 mm, and a length of about 50 cm [manufactured by the Hydrochemical Industries. Product name: A rainwater storage structure assembly (A) having a height of about 3 m and a width of about 3 m as shown in FIG. 4 and FIG. 5 using the connection jig shown in FIG. 1 using Eslon Haifa PE). ) Was formed, placed in a pit having a predetermined internal volume of about 5 m depth, and a rainwater retention structure was constructed. The polyethylene pipe has a compressive strength of about 27 kN / piece in the longitudinal direction, and when four pieces are used per 1 m ² , a compressive strength of 108 kN / m ² can be obtained, and the cover is 2 m (load: about 36 kN / m ² ). Even in this case, a compressive strength of about three times stronger can be obtained, which indicates that it is practical enough.

In fact, a rainwater storage structure was constructed with a size of 1m × 1m × 1m, and a weight equivalent to 2m of cover soil was installed from the rainwater storage structure, but more than one year had elapsed. The problem did not occur at all.

The outer diameter of) and the outer diameter of the cylindrical connecting end portion 12a of the connecting member 12 have substantially the same dimensions. In this case, when assembling both members, the unevenness in the longitudinal direction in the granulated material A for rainwater storage structures is reduced, and it is preferable because it is possible to prevent things other than earth and sand in this portion from being laminated. First of all, the connection between the pipe-shaped vertical member 11 and the connecting member 12 may be vertically installed in the pit after connecting the pipe-shaped vertical member 11 and the connecting member 12.

In that case, although the connection end part 12a of the new connection member 12 overlaps with the upper part of the connection end part 12a of the existing connection member 12, the step may generate | occur | produce in height, while repeating several connection. have. However, the step can be adjusted by using a cylindrical spacer 13 having a predetermined height and having an inner diameter that can be externally coupled to the cylindrical portion 11a of the pipe-shaped vertical member 11. Moreover, also when connecting the pipe-shaped vertical members 11 in a height direction, it can carry out using the spacer 13 of a suitable length. By repeating such an operation, it is possible to construct a rainwater storage structure granulated material A in the form of a jungle gym.

The construction example which uses the rainwater storage structure granulated body A which assembled the rainwater storage structure assembly member which concerns on 2nd Example for a rainwater storage structure can also be comprised as shown in FIG. Excavate and form a recess (pit) of about 1 to 5 m on the ground, form side grooves (7) around the pit, lay and level the foundation (B) by laying and laying crushed stone and sand on the bottom of the pit. Form. After laying the order sheet 4 on the surface of the said bubble B, from the resin pipe-shaped longitudinal member 11 and the connection member 12, in the order shown to FIG. Consists of a rainwater storage structure assembly (A) according to the jungle gym. When the pit contents are large, the rainwater storage structure granulated material A may be assembled in the pit or the rainwater storage structure granulated material A may be assembled outside the pit and then inserted into the pit. It is the same as in the case of the first embodiment that the granulated material for rainwater storage structure A thus assembled is fastened and fixed with a belt made of resin or metal. In addition, a square panel may be sandwiched between the pipes on the side outer periphery to ensure flatness at the side outer periphery and to increase the strength. Also for the rainwater storage structure granulated material A which is the three-dimensional structure of a present Example, it can be made to have a compressive strength of at least 108 kN / m <^2> or more.

(Example 2)

The actual construction example is demonstrated. According to the procedure shown in Figs. 7 to 10, using polyethylene pipes (approx. A rainwater storage structure assembly of about 3m was formed, placed in a pit having a predetermined internal volume of about 5m in depth, and a rainwater storage structure as shown in FIG. 6 was constructed. Also in this case, similarly to the case of the first embodiment, the polyethylene pipe has a compressive strength of about 27 kN / piece in the longitudinal direction, and when four pieces are used per 1 m ² , a compressive strength of 108 kN / m ² can be obtained. Even when the value of 2 m (load: about 36 kN / m ² ) is obtained, a compressive strength of about 3 times stronger can be obtained, which indicates that it is sufficiently practical.

In fact, a rainwater storage structure was constructed with a size of 1m × 1m × 1m, and a center equivalent to 2m of cover soil was installed from the rainwater storage structure. It didn't happen.

(Third Embodiment)

EMBODIMENT OF THE INVENTION The 3rd Example which concerns on this invention is described in detail with reference to drawings. FIG. 11: shows the perspective view of the unit block which assembled the connection jig 1, the horizontal member 22, and the pipe-shaped vertical member 3 used as the rainwater storage structure assembly member which concerns on 3rd Example. That is, FIG. 12 is a perspective view seen from the upper surface direction of the horizontal member 22, and FIG. 13 shows the perspective view seen from the bottom face side of the horizontal member 22 of FIG.

The connecting jig 1 is made of resin and, as shown in Fig. 11, protrudes from the cylindrical portion 1a that can be externally coupled to the vertical member 3 and the four parts of the outer circumferential surface, and is joined to the end of the horizontal member 22. It has the protrusion part 1b which connects both. In the protruding portion 1b, four through holes 1c are formed to receive and engage the end projections 22a of the horizontal member 22 described later. In the tubular portion 1a, a slightly small through-hole is formed to reduce the weight, and to move the rainwater downward to store water.

The pipe-shaped vertical member 3 is made of resin, has a cylindrical shape with a predetermined length, and can be internally coupled to the tubular portion 1a of the connecting jig 1.

The horizontal member 22 is also made of resin, and as shown in Figs. 12 and 13, the end projections 22a inserted into and coupled to the through holes 1c of the connecting jig 1 are downward at both end portions on the rear side. At the same time, a recess 22b opened downward is formed between the end projections 22a. Moreover, two predetermined space | intervals are made empty in the longitudinal direction so that the recessed part 22b may be divided, and the longitudinal direction rib 22c for reinforcement is formed. Also in the short side direction, the reinforcing short side rib 22d is formed in many parts (three parts in FIG. 13), and the recessed part 22b is partitioned. By forming the longitudinal ribs 22c, a large strength can be exhibited with respect to the compressive force acting from the longitudinal direction of the horizontal member 22. By forming the short side ribs 22d, the durability can be exerted with respect to the external force in the screw direction acting on the horizontal member 22. The heights of the longitudinal ribs 22c and the short side ribs 22d are slightly lower than the heights of the longitudinal barriers 22e forming the recesses 22b, and the weight is reduced accordingly. This is because the strength of the ceiling surface on the surface side where the shallow grooves 22h are formed over the longitudinal direction of the horizontal member 22 and the strength balance of the longitudinal ribs 22c and the short side ribs 22d are formed. By Originally, when the strength of the ceiling surface of the horizontal member 22 is high, the heights of the longitudinal ribs 22c and the short side ribs 22d are equal to the heights of the longitudinal barriers 22e forming the recesses 22b. Similarly, it is preferable to balance strength. Of course, the number, position, shape, etc. of the reinforcing ribs 22c can be variously changed. In addition, as shown in FIG. 12, many water-fusing through holes 22f are drilled in the ceiling surface on the surface side of the horizontal member 22 at a predetermined interval.

In forming the rainwater storage structure assembly A constituting the three-dimensional structure in the jungle gym form, the connecting jig 1 is attached to the upper end of each vertical pipe member 3 installed vertically, and two pipes are mounted. The end projections 22a of the horizontal members 22 are inserted into the through holes 1c of the two connecting jigs 1 adjacent to each other among the connecting jigs 1 mounted on the mold vertical member 3. Insert and join. In addition, the pipe-shaped vertical member 3 and the horizontal member 22 are connected, and this is repeated.

It is preferable that the granulated material for rainwater storage structures A which is a three-dimensional structure has a compressive strength of at least 108 kN / m ² or more. In this way, even if a cover ² m (load: about 36 kN / m ² ) is applied to the top, it has sufficient strength three times or more of the earth pressure. Specifically, when combining a pipe-shaped longitudinal member of about 40 cm in length and a horizontal member of 40 cm in length, at least a compressive strength of 6.25 pieces / m ² is about 17.28 kN / p.

By doing in this way, rainwater can be stored once and used for various uses, such as spray water, washing water, and emergency water, such as a garden, or it can be provided with the adjustment function so that a large quantity of rainwater may be discharged gradually. In addition, since the curing period and the like are unnecessary as compared with the case of concrete, the construction speed of the rainwater storage structure can be significantly increased.

(Modification 1)

The modification of the connection member which comprises the assembly member for rainwater storage structures is demonstrated with reference to FIG. 14, FIG. As for the said connection member 21, four protrusion parts 21b are formed in the substantially center part of the height direction of the cylindrical part 21a, and the through-hole 21c is formed in each protrusion part 21b, It is the same as the connection member 1 shown in FIG. However, four elongated portions 21d are formed between the protrusions 21b, four longitudinal grooves 21e are formed in the upper and lower cylindrical portions 21a, and the elongated portions 21d are provided. The upper end side of has an upper point which forms the elongate protrusion part 21f which protruded slightly. Since four projection parts 21d are formed between each protrusion 21b, when the horizontal member 22 is connected, the horizontal member 22 can be prevented from rotating in a horizontal direction (rotation stop mechanism). . As a result, each time the construction work is performed, the horizontal member 22 does not rotate unintentionally, so it is easy to work and exhibits the effect of suppressing the downward bending of the horizontal member at the time of construction work.

Since the connection member 21 is comprised in this way, when the vertical member 21a is moderately expanded and deformed when the vertical member is joined to the upper and lower cylindrical portions 21a, the design freedom of the vertical member is slightly increased, Dimensional flexibility of the vertical member is increased, and construction workability is improved. In addition, also about connection with the horizontal member 22, the recessed part 22g of the cross section side of the barrier 22e formed in the horizontal member 22, and the upper end side of the elongate part 21d of the connection member 21. 21 f of eruption protrusions formed in the coupling | bonding are joined, and the connection of the connection member 21 and the horizontal member 22 becomes more firm, and the rainwater storage structure assembly A which assembled the rainwater storage structure assembly member was assembled. The strength is significantly improved. The connection of the connection member 21 and the horizontal member 22 descend | falls the horizontal member 22 in the direction shown by the arrow R from the state of FIG. 14 (before connection), and is shown in FIG. 15 (after connection). It is in a state.

As shown in FIG. 14, FIG. 15, the recess 22h is formed in the ceiling surface of the surface side of the horizontal member 22 in the longitudinal direction, and the through-hole 22f for draining is formed in the bottom part. It is. The shape, number, and the like of the grooves 22h can be changed as appropriate. The number, diameter, and the like of the water draining through-hole 22f can also be appropriately changed. In addition, compared with the case where the groove is formed into a simple arc shape, when the wave is formed in a wave shape, the strength against deformation in the horizontal direction is particularly high.

(Modification 2)

Also about the pipe-shaped vertical member 3, you may attach the vertical rib 14 for reinforcement to the outer peripheral surface along the up-down direction, as shown in FIG. The longitudinal ribs 14 have a fine width form extending upward and downward in the center portion of the outer circumferential surface excluding the upper and lower ends of the pipe-shaped vertical member 3, and approximately on the outer circumferential surface of the pipe-shaped vertical member 3. Four are mounted at equal intervals. Two of the longitudinal ribs 14 are formed with drain holes 14a in two upper and lower portions of the longitudinal ribs 14. If comprised in this way, the intensity | strength, especially buckling strength, etc. of the pipe-shaped vertical member 3 can be improved significantly with a simple structure. The width, length, number, etc. of the longitudinal ribs 14 can be changed in various ways. The material is preferably the same material as that of the pipe-shaped longitudinal member 3, but may be a different material. Moreover, the vertical rib 14 may be attached to the inner peripheral surface side of the pipe-shaped vertical member 3, and may be integrally molded as a pipe-shaped vertical member with a rib initially.

When the pipe (outer diameter of about 60 mm, thickness of about 4 mm, length of about 400 mm, and bending elastic modulus of 1700 MPa) shown in FIG. 16 was used, the compressive strength of 200 kN / m ² was obtained.

(Modification 3)

In the top position of the connecting member 11 shown in FIG. 14, FIG. 15, since the pipe-shaped vertical member 3 is not connected, the cylindrical part 21a which faces upwards becomes unnecessary. Therefore, it is preferable to remove the protruding part of the upper part of the cylindrical part 21a, and to mount the cap member 15 shown in FIG. The cap member 15 is composed of a thin disk-shaped top portion 15a and an inner cylinder portion 15b that is internally coupled to the center hole 21g of the connecting member 21, and the circumference of the outer circumferential surface of the inner cylinder portion 15b. There are six staircase ribs 15c in the vertical direction at substantially the same interval. And when the inner cylinder part 15b of the cap member 15 is attached to the center hole 21g of the uppermost part of the connection member 21, the lower part and the center of the diameter-expanded elongate rib 15d which contact the top part 15a will be attached. The peripheral edge of the hole 21g is in contact with each other, and the upper end portion of the horizontal member 22 is insertable into a gap formed between the top portion 21a. In this way, the uppermost position of the connection member 21 is kept substantially smooth, and it is possible to prevent the external force from acting from the inadequate direction during or after construction, and at the same time, the strength of the portion is at least constant. Is maintained. The cap member 15 may be mounted at the top position of the connection member 1 shown in FIG. 11 as well as the top position of the connection member 21 shown in FIGS. 14 and 15.

(Modification 4)

In addition, when assembling work | work of the rainwater storage structure assembly A, the plate-shaped panel 16 shown to FIGS. 18-21 is sandwiched between the pipe-shaped longitudinal members 3, and on the horizontal member 2. As shown in FIG. It is possible to secure the flatness to increase the assembly workability while increasing the strength of the granulated material A for rainwater storage structures. The panel 6 shows a left side structure in FIG. 18, a planar structure in FIG. 19, a bottom structure in FIG. 20, and an AA cross-sectional structure in FIG. 20 in FIG. 21. It is easy for the worker to walk, and a plurality of holes 17 (four in Figs. 19 and 20) close to the outer circumference are drilled to bind panels 16 adjacent to both sides with a band made of polypropylene. You can do it. Moreover, the uneven | corrugated part 18 which made it possible to convey in the state which laminated | stacked many sheets of the panel 16 protruded to the back side, and formed many pieces (four in FIG.19, FIG.20), and the panel of the upper surface side The convex part which protrudes on the back surface of (16) is engaged with the recessed part of the upper surface of the panel 16 of the lower surface side, and the panel 16 which overlapped many sheets is prevented from shifting at the time of conveyance with each other.

On the back side, a turtle shell shape is formed, and they also act as reinforcing ribs, and at the same time, weight reduction and strength enhancement are achieved. In addition, the four corners of the panel 16 are formed in substantially 1/4 arc shape so that surface contact with the connection members 1 and 21 is possible. In addition, at the time of actual construction, it is also possible to arrange | position and use the surface and back surface of the panel 16 reversely.

(Modification 5)

In addition, the side panel 19 as shown in FIGS. 22-24 may be attached to the side outer peripheral part of the rainwater storage structure granulated body A, and the intensity | strength of the rainwater storage structure granulated body A may be improved. The side panel 19, like the front structure shown in Fig. 22, has a structure that is open in the shape of a turtle's shell over its entire surface. The engaging part 19a which hangs on the member 3 is provided. The locking portion 19a can be formed in various structures. For example, the pipe-shaped longitudinal member 3 having the longitudinal ribs 14 shown in FIG. 16 is a pair of pairs coupled to the longitudinal ribs 14, as shown in FIG. 24, the planar structure of the side panel 19. FIG. A latching system in which the projections 19b are formed on the side panel 19 and the vertical ribs 14 are sandwiched between the pair of projections 19b can be considered. By attaching such side panels 19 to the side outer periphery of the rainwater storage structure assembly A or the side of the unit block as appropriate, it is possible to exert a great resistance against ground displacement and the like.

Moreover, in order to reinforce the shell shape of the turtle formed over the whole surface of the side panel 19, you may form a straight horizontal rib or a straight longitudinal rib so that a turtle may cross the shell shape. If such a rib is formed, even if an external force is applied, the side panel 19 will be hard to bend, and it can make it hard to separate from the pipe-shaped longitudinal member 3.

The construction example which uses the rainwater storage structure granulated body A which assembled the rainwater storage structure assembly member which concerns on the said 3rd Example for a rainwater storage structure can also be comprised as shown in FIG. Excavate and form a ground recess (hereinafter sometimes referred to as a pit) of about 1 to 5 m on the ground, form side grooves 7 around the pit, and lay and construct crushed stone, sand, etc. on the bottom of the pit. The solution is leveled to form the base B. After laying the order sheet 4 which is a liner material on the surface of the said foundation, the footrest is further extended, forming the unit block shown in FIG. 1 from each pipe-like longitudinal member 3 and connection jig 1 made of resin. Then, the rainwater storage structure granulated material A of the jungle load type according to the volume of the pit is disposed.

Then, the side surface portion of the rainwater storage structure assembly A disposed in the pit is buried as necessary, returns (C), and communicates so that rain water can flow into the pit from the side grooves 7. (8) is laid and the top sheet 5 is coated on the upper surface, and the soil 6 of about 0.5 to 1 m is covered from the top sheet 5 to cover the soil sheet 6. These, the order sheet 5 of the upper surface, the cover 6, etc. form a coating layer. In addition, the inspection hole may be formed in the some part of these coating layers 6. And instead of covering the order sheet 5 on the upper surface of the granulated material for rainwater storage structures A, you may coat a permeable sheet and let rainwater infiltrate. As for the side groove 7, the bottom part is deepened so that the airflow 9 may be formed in the bottom part.

(trade name: Fuji Polypropylene-PP)) and a connecting jig having an outer diameter of about 60 mm, a thickness of about 5.0 mm, and a length of about 40 cm, as shown in FIG. 2 and FIG. 3. , A rainwater storage structure assembly A having a height of about 3m and a width of about 3m was formed, placed in a pit having a predetermined inner volume of about 5m in depth, and a rainwater storage structure was constructed. The polypropylene pipe has a compressive strength of about 105 kN / 4 (26.25 kN / piece) in the longitudinal direction, and when 6.25 pieces are used per 1 m ² , a compressive strength of 16OkN / m ² can be obtained, resulting in 2m ( Even in the case of a load: about 36 kN / m ² ), since the compressive strength is about 4.5 times stronger, it can be seen that it is sufficiently practical.

Actually, a rainwater storage structure was constructed with a size of 1.2m × 1.2m × 1.2m (since 1 unit has a pitch of 0.4m), and a weight corresponding to 2m of cover soil was mounted therefrom, but more than one year passed. No deformation or other problems that would be a problem in use occurred.

(Example 6)

27 shows a schematic front sectional structure of the rainwater storage structure according to the sixth embodiment. After arrange | positioning the granulated material for rainwater storage structures A on the order sheet 4, and covering it, it is a non-woven fabric or resin net material which is a water permeable material with flexibility, or a non-woven fabric or resin mat material, Alternatively, the resin-coated net material (hereinafter sometimes referred to simply as mat material) 30 is coated over the side and top surfaces of the granules A for rainwater storage structures. The peripheral end of the mat member 30 is arranged at the periphery of the extra excavation portion 31b excavated slightly lower than the ground around the pit, and as a result, the mat member 30 is disposed around the extra excavation portion ( 31b), an extra excavation part surface 31a, and the side surface and upper surface of the rainwater storage structure assembly A are arrange | positioned. Moreover, although it is preferable that the peripheral edge part of the mat material etc. 30 is arrange | positioned to the extra excavation part periphery 31b, it is not necessary to necessarily reach the extra excavation part periphery 31b, and at least the extra excavation part surface It is sufficient to reach (31a).

Subsequently, when the upper surface and the entire surface of the mat member 30 and the like are pressurized and coated by their own weight by the filler 32 made of a stone such as crushed stone or soil, which fills the pit, the mat member or the like 30 is firmly mounted along the side and the upper surface of the rainwater storage structure assembly (A), to strongly press the rainwater storage structure assembly (A). As a result, in addition to the rainwater stored in the rainwater storage structure, even when the groundwater level rises due to rainy season or the like, it is possible to reliably prevent the situation where the rainwater storage structure assembly A floats. Air gaps are formed between the fillers 32, and rainwater can be stored in this portion as well, and in parallel with the mat member or the like 30 covering the granules A for rainwater storage, soils and dust Or other foreign matter to prevent the entry of rainwater storage structural assembly (A). As the packing material 32, it is preferable to consist of stones, such as agglomerated crushed stone and earth, etc., but it may be crushed concrete, etc., and it should just be what consists of a stone rotor mainly.

In addition, a pipe-shaped inlet 33 through which rainwater flows in around one side of the pit is provided, and a pipe-shaped outlet 34 capable of discharging the overflowed rainwater on the other side is provided. By doing in this way, rainwater can be reliably guided into the rainwater storage structure assembly A from the surroundings, and it can be stored therein. When overflowed, the rainwater is discharged from the outlet toward the sewer and the like. The low volume in A) can always be adjusted. In this case, it is not necessary to directly connect the inflow port 33 and the outflow port 34 to the rainwater storage structure granulated material A, and therefore, the structure of this part can be simplified. This is because the gap portion between the crushed stones 32 filled in the extra excavation portion 31 also achieves the function of rainwater storage.

It covers with the cover material 6 of about 0.5-1 m from the mat material etc. 30 and the crushed stone 32 on a rainwater storage structure, adjusts height with a ground, and finishes with the surface according to the objective. In that case, one or more inspection holes may be formed in the appropriate position of the said rainwater storage structure. By forming such a check hole, for example, the convection generation mechanism which convections the rain water stored in the inside of the rainwater storage structure assembly A can be detachably inserted from the check hole, and the convection of the predetermined time can be performed. By periodically or irregularly, it is possible to clean the inside of the granulated water for rainwater storage structure A, and to keep the water storage function high at all times.

Moreover, although it is preferable that it is comprised from a nonwoven fabric etc. as a water permeable material which coats the granulated material for rainwater storage structures (A), it is not limited to this especially, and a covering does not easily enter the granulated material for rainwater storage structures (A), What is necessary is just to be flexible and to withstand the weight of crushed stone.

(Other embodiment)

(1) In the above embodiment, although polypropylene is exemplified as a constituent material of the resin pipe-type longitudinal member, it is not limited thereto, and polyethylene, polyvinyl chloride, PET (polyethylene terephthalate; polyethylene telephthalate) Various thermoplastic resins may be used as long as the required strength can be obtained. In addition, the pipe-type longitudinal member may be made of a metal pipe such as stainless steel instead of resin, and concrete may be injected into the resin pipe-shaped vertical member, or reinforced steel may be inserted and reinforced.

(2) Although the pipe member, the horizontal member, and the connecting jig are made of resin of the same material, they may be made of resin of different materials.

(3) You may make powdered calcium carbonate (carbon knife) etc. mix in the constituent material of a resin pipe-shaped member, a horizontal member, and a connection jig | tool. This makes it possible to increase the specific gravity of the constituent material, to resist buoyancy generated when rainwater is stored, and to prevent buoyancy, special construction is unnecessary, and even a small space can secure a larger amount of water. . Specifically, specific gravity can be made 1.0 or more by mixing about 13% of the carbon knife into resin.

(4) In the case of mixing in the constituent material, whiskers such as talc and barium sulfate may be mixed in place of the carbon. These have a large aspect ratio ratio and a large effect of increasing the strength compared to carbon. Moreover, you may mix glass fiber in the said structural member. Glass fiber is preferable because it can not only increase the specific gravity of a structural member, but can also raise strength and dimensional stability. For example, when 4.6 wt% of glass fibers (30 parts of 20 wt% of the master batch 100) are added, the specific gravity is 0.03, the strength is increased by 15%, and the shrinkage is 0.4% at the time of molding.
