Description

  The present invention relates to a storage and penetration facility and a gutter structure including the storage and penetration facility.

  2. Description of the Related Art Conventionally, a storage and penetration facility that is buried in the ground, such as a storage and penetration tank that temporarily stores rainwater or the like and then permeates into the ground, is known. In general, this type of storage and penetration facility has a water-permeable sheet placed in a hole (hereinafter referred to as a pit) formed by digging the ground surface, and a plurality of storage materials composed of resin materials or the like are placed on the sheet. After the arrangement, the sheet is placed on the storage material. After the storage and penetration facility is installed, the storage and penetration facility is buried by placing soil on the sheet and filling the pits.

  Moreover, in order to infiltrate rain water and the like on the road into the ground, an infiltration side groove structure is known in which an infiltration side groove is disposed on a side of the road and a storage infiltration facility is disposed under the infiltration side groove. . As an example of this type of infiltration side groove structure, Patent Document 1 discloses an infiltration side groove structure in which an infiltration side groove is placed on a storage infiltration facility (an infiltration water storage tank) via a permeable floor plate. ing. This water-permeable floor board is a perforated concrete floor board or a water-permeable concrete floor board, and is made at a construction site. In addition, this water-permeable floor board functions as a load distribution board, and even if a large concentrated load acts on the permeation side groove, the storage material of the storage permeation tank made of a resin material is deformed. It is preventing.

JP 2010-127052 A

  By the way, depending on the circumstances of the construction site, unevenness (that is, unevenness of the surface) may occur in the pit, and at least a part of the storage material is arranged in a slightly inclined posture from the vertical direction according to the unevenness. There is a case. When a storage and infiltration facility is arranged in a pit where such unevenness occurs, the upper surfaces of the storage materials do not become flush with each other. The upper surface of the facility storage material may be tilted with respect to the ground surface. Therefore, when the permeation side groove is disposed on the storage material disposed in this way via the water-permeable floor plate described in Patent Document 1, the upper surface of the permeation side groove and the ground surface may not be flush with each other. In addition, since the floor board is made of concrete, if the upper surface of the storage and penetration facility is uneven, a gap may be formed without the contact between the floor board and the storage material. In addition, when a large concentrated load is applied to the permeation side groove, the gap is generated, and therefore a large load is locally applied to a specific portion in contact with the floor plate of the storage material, so that suitable load distribution can be achieved. However, the storage material may be deformed. On the other hand, when unevenness occurs in the pit, it is conceivable to form the floor board in a shape corresponding to unevenness. That is, it is conceivable to make the floorboard at the construction site so that the upper surface of the floorboard is substantially horizontal along the upper surface of the storage material of the storage and penetration facility. However, since the shape of the unevenness in the pit differs depending on the unevenness, making a floorboard corresponding to the unevenness requires time and effort.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a storage and infiltration facility that can disperse a load applied to the storage and infiltration facility and cope with unevenness, and the same. It is to provide a gutter structure.

  The storage and penetration facility according to the present invention is a storage and penetration facility buried in the ground. The said storage penetration facility is equipped with the storage material which can store water, and the buffer board which is arrange | positioned on the said storage material and has water permeability. The buffer plate has an elastic body that directly or indirectly contacts the storage material.

  According to the present invention, since the buffer plate is arranged on the storage material, when a large concentrated load is applied from above, the concentrated load can be dispersed by the buffer plate, and a large force is applied to the storage material. This can be prevented. Since the buffer plate has water permeability, rainwater or the like can be introduced into the storage material via the buffer plate. Since the buffer plate has an elastic body that is in direct or indirect contact with the storage material, when the upper surface of the storage material is inclined from the horizontal plane due to unevenness, the elastic body elastically deforms so as to cancel the inclination. The upper surface of the buffer plate can be made substantially horizontal. Therefore, it is possible to prevent the buffer plate and the storage material from evenly contacting each other directly or indirectly and applying a large load locally to a part of the storage material. Moreover, it can suppress that an impact load is added to the storage material by the elastic body of a buffer plate. Therefore, according to the present invention, it is possible to prevent the storage material from being deformed or broken.

  According to a preferred aspect of the present invention, a plurality of the storage materials are provided. The plurality of storage materials are arranged side by side. The buffer plate is disposed on the plurality of storage materials.

  In the case where a plurality of storage materials are arranged side by side, the influence of unevenness in the pit tends to increase. If there is unevenness in the pit, it will be difficult for the storage materials to be aligned. If the buffer plate is made of concrete, there will be a space where the buffer plate and the storage material should be in direct or indirect contact with each other, and the buffer plate will be stored. There is a risk of not contacting the material uniformly. However, since the buffer plate includes the elastic body, the space is eliminated when the elastic body is deformed, and the elastic body of the buffer plate and the storage material are in direct contact or in uniform contact. As a result, the load applied to the storage material can be favorably dispersed. Further, even if the storage material is slightly inclined, the upper surface of the buffer plate can be kept substantially horizontal, and the buffer plate can suitably receive a load from the ground surface.

  According to another preferable aspect of the present invention, the plurality of storage materials are arranged so as to be stacked vertically. The buffer plate is disposed on the uppermost storage material among the plurality of storage materials.

  In the case where a plurality of storage materials are stacked vertically and arranged in the horizontal direction, the influence due to unevenness in the pit tends to be further increased. Therefore, if there is unevenness in the pit, the storage materials will not overlap each other. However, when the buffer plate includes the elastic body, the elastic body is deformed, so that the elastic body of the buffer plate and the storage material are in direct contact with each other uniformly or indirectly. As a result, the load applied to the storage material can be favorably dispersed. Further, even if the storage material is slightly inclined, the upper surface of the buffer plate can be kept substantially horizontal, and the buffer plate can suitably receive a load from the ground surface.

  According to another preferable aspect of the present invention, a plurality of the elastic bodies are provided. The buffer plate includes a base plate to which the plurality of elastic bodies are attached and a plurality of holes are formed.

  As a result, since a plurality of elastic bodies are provided, the buffer plate is easily elastically deformed following the irregularities on the upper surface of the storage material. When a concentrated load is applied from the ground surface, the load applied to the storage material can be suitably dispersed. In addition, since the base plate has a plurality of holes, rain water or the like can be introduced into the storage material by passing rain water or the like through the plurality of holes of the base plate.

  According to another preferable aspect of the present invention, the base plate is made of a resin material.

  Since the base plate is made of a resin material, it is lightweight unlike a buffer plate made of concrete. Therefore, it is easy to prepare a buffer plate in advance and transport the prepared buffer plate to the construction site. Therefore, the work burden at the construction site can be reduced.

  According to another preferable aspect of the present invention, the seal member is disposed between the buffer plate and the storage material and seals at least a part of the periphery between the buffer plate and the storage material. ing.

  The sealing member can prevent rainwater or the like that has passed through the buffer plate from flowing out without flowing into the storage material. As a result, rainwater or the like can be suitably stored in the storage material.

  According to another preferable aspect of the present invention, the storage material is made of a resin material.

  A storage material made of a resin material is easily deformed when a concentrated load is applied. However, the load applied to the storage material can be dispersed by disposing the buffer plate on the storage material, so that the storage material can be prevented from being deformed or broken.

  According to another preferable aspect of the present invention, a rainwater receiver that extends outward from the side end of the buffer plate is provided.

  By receiving rainwater, not only rainwater flowing from above the buffer plate but also rainwater flowing from diagonally above the buffer plate can be introduced into the storage material. As a result, more rainwater or the like can be introduced into the storage material.

  The side groove structure of the present invention includes any one of the above-described storage and permeation facilities, and a side groove that is disposed on the buffer plate of the storage and permeation facility and has water permeability.

  According to the lateral groove structure of the present invention, when the storage material is disposed in the pit where unevenness has occurred, the buffer plate having the elastic body is disposed on the storage material, so that the upper surface of the buffer plate is substantially horizontal. It becomes. Therefore, when the side groove is disposed on the buffer plate, the upper surface of the side groove and the ground surface are likely to be flush with each other. Moreover, since the buffer plate and the storage material are in contact with each other uniformly, the side groove is not wobbled and is disposed on the buffer plate. Since the side groove is arranged on the storage material, the load of the side groove itself and the load from the ground are applied to the storage material. However, since there is a buffer plate between the storage material and the side groove, the load applied to the storage material can be dispersed. As a result, it is possible to prevent the storage material from being deformed or broken.

  According to a preferred aspect of the present invention, the side groove is composed of a plurality of side groove blocks. The side groove block includes a bottom wall in which holes are formed. The side groove structure includes seal members that are disposed between the bottom wall of the side groove block and the buffer plate and on both sides of the hole in the bottom wall and extend in the longitudinal direction of the side groove.

  By arranging the seal member between the bottom wall of the side groove block and the buffer plate in this way, it is possible to prevent rainwater or the like flowing from the side groove from flowing out of the buffer plate. As a result, rainwater or the like from the side groove can be efficiently introduced into the storage material via the buffer plate.

  According to the present invention, it is possible to provide a storage and penetration facility that can disperse a load applied to the storage and penetration facility and can cope with unevenness, and a gutter structure including the storage and penetration facility.

FIG. 3 is a plan view showing the buffer plate 30. 4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIG. 3, the buffer plate 30 of the present embodiment has a substantially rectangular shape in plan view, but the shape is not limited. The buffer plate 30 includes an elastic body 40 and a base plate 36 which will be described later.

  A plurality of elastic bodies 40 are provided on the buffer plate 30. In the present embodiment, the elastic body 40 is a rubber elastic body that has a substantially cylindrical shape and expands and contracts at least in the vertical direction. However, the elastic body 40 may not be made of rubber as long as it is an elastic body that expands and contracts at least in the vertical direction, and the shape is not limited. As shown in FIG. 4, the lower part of the elastic body 40 protrudes downward. The elastic body 40 is in indirect contact with the storage material 10A. In the present embodiment, the elastic body 40 is indirectly in contact with the top plate 15 of the storage material 10A in the second stage from the bottom through the sheet 2. The plurality of elastic bodies 40 are arranged in the longitudinal direction and the width direction. The plurality of elastic bodies 40 are arranged in a scattered manner. The plurality of elastic bodies 40 are arranged at equal intervals. The plurality of elastic bodies 40 may not necessarily be arranged at equal intervals, but the elastic body 40 is positioned above the side plate 14 of the storage material 10A when the buffer plate 30 is arranged on the storage material 10A. It is preferable. That is, the elastic body 40 is preferably in indirect contact with a portion of the upper surface of the top plate 15 of the storage material 10A that is connected to the upper end portion of the side plate 14. When the buffer plate 30 is disposed on the storage material 10 </ b> A, the plurality of elastic bodies 40 are preferably disposed so as not to overlap the water-permeable holes 12 of the top plate 15. It may overlap.

  As shown in FIG. 3, the buffer plate 30 includes a base plate 36. A plurality of elastic bodies 40 are attached to the base plate 36. In the present embodiment, the plane of the base plate 36 has a lattice shape. Specifically, the base plate 36 includes a plurality of rod-shaped support members 37 and an outer frame 34 that surrounds the plurality of support members 37 and the elastic body 40. A plurality of support members 37 form a lattice of the base plate 36. However, the plane of the base plate 36 is not limited to a lattice shape, and for example, the upper surface and / or the lower surface of the base plate 36 may be a flat or uneven surface. An elastic body 40 is attached to the tip of the support member 37. The elastic body 40 is supported by the plurality of support members 37.

However, the material of the base plate 36 is not limited to resin, and part or all of the base plate 36 may be made of a material other than resin.

  As shown in FIG. 4, the storage and penetration tank 1 </ b> A of the present embodiment includes a seal member 44. The seal member 44 seals at least a part of the periphery between the buffer plate 30 and the storage material 10A. The seal member 44 is disposed between the buffer plate 30 and the storage material 10A. In the present embodiment, the seal member 44 is attached to the lower surface of the outer frame 34 of the buffer plate 30. The seal member 44 is attached to the lower surface of the outer frame 34 of the buffer plate 30 so as to surround the plurality of support members 37 and the elastic body 40. However, the seal member 44 may be attached only to a part of the lower surface of the outer frame 34. Although the seal member 44 is formed separately from the outer frame 34, the seal member 44 and the outer frame 34 may be formed integrally. In this embodiment, since the seal member 44 is attached to the lower surface of the outer frame 34, the seal member 44 is disposed outside the seat 2, but the seal member 44 is not attached to the outer frame 34, It may be disposed inside the sheet 2 and may be in contact with the storage material 10A. In this case, the seal member 44 is in contact with the buffer plate 30 via the seat 2. The seal member 44 may be attached to the lower surface of the buffer plate 30 other than the outer frame 34. The height of the seal member 44 is not particularly limited, but when the buffer plate 30 is disposed on the storage material 10A, the elastic body 40 of the buffer plate 30 indirectly contacts the storage material 10A, and the seal member 44 is It is preferable that the height be in contact with the storage material 10A indirectly. In addition, the seal member 44 is preferably in contact with the storage material 10A indirectly and uniformly, but at least a part of the seal member 44 may be in contact with the storage material 10A indirectly. In the present embodiment, the seal member 44 is configured by an elastic body. However, the material of the seal member 44 is not limited as long as at least a part between the buffer plate 30 and the storage material 10A can be sealed.

  Next, a method for embedding the storage and penetration tank 1A according to the present embodiment in the ground will be described. As shown in FIG. 1, first, pits 5 are formed by digging the ground surface. Then, a permeable sheet 2 is laid on the formed pit 5, and a plurality of storage materials 10 </ b> A are installed on the sheet 2. In FIG. 2, three first-tier storage materials 10A in the width direction and four rows in the length direction are arranged on the sheet 2 so as to be arranged side by side. The four or more rows of storage materials 10A are arranged on the sheet 2 so as to be arranged horizontally in the length direction. Further, as shown in FIG. 1, the second-stage storage material 10 </ b> A is arranged on the first-stage storage material 10 </ b> A. Then, the sheet 2 is placed on the second-stage storage material 10A, and the buffer plate 30 is disposed on the second-stage storage material 10A via the sheet 2. At this time, the buffer plate 30 is disposed on the storage material 10A so that the plurality of storage materials 10A are hidden in a plan view. Thereafter, the buffer plate 30 is covered with soil, and the storage and penetration tank 1A is buried in the ground.

  Rainwater penetrates into the ground as follows. First, rainwater penetrates into the soil above the storage and penetration tank 1A buried in the ground. The rainwater that has penetrated into the soil passes through the water-permeable holes 38 of the buffer plate 30 and reaches the sheet 2 between the buffer plate 30 and the storage material 10A. Thereafter, since the sheet 2 has water permeability, rainwater passes through the sheet 2. At this time, the rainwater may contain dust and the like, but the dust and the like are removed when passing through the sheet 2. Rainwater that has passed through the sheet 2 temporarily accumulates in the space inside the storage material 10A via the water-permeable holes 12 of the storage material 10A. Thereafter, rainwater penetrates into the ground below the sheet 2 through the sheet 2. In this way, rainwater penetrates into the ground.

  Next, the buffer plate 30 when the pit 5 is uneven is described. FIG. 5 is a diagram illustrating the storage material 10 </ b> A and the buffer plate 30 when unevenness occurs in the pit 5. However, the illustration of the sheet 2 is omitted in FIG. Depending on the circumstances of the construction site, unevenness may occur in the pit 5, and at least a part of the storage material 10 </ b> A may be desired to be disposed with a slight inclination from the vertical direction according to the unevenness. When unevenness occurs in the pit 5, the sheet 2 is laid on the pit 5, and a plurality of storage materials 10 </ b> A are arranged on the sheet 2, as shown in FIG. 5, the top surface of the top plate 15 of the storage material 10 </ b> A is If they are not aligned, that is, a part of the top surface of the top plate 15 may protrude or dent. In this embodiment, even in such a state, the sheet 2 is placed on the storage material 10A, and the buffer plate 30 is disposed on the storage material 10A.

  The storage material 10A is pressed downward by the buffer plate 30 by the weight of the buffer plate 30 before burying, and by the weight of the buffer plate 30 and the weight of the soil on the buffer plate 30 after burying. Repulsive force is received from the material 10A. At this time, among the elastic bodies 40 of the buffer plate 30, the elastic body 40 disposed at the protruding portion 15 </ b> A of the top plate 15 in the storage material 10 </ b> A is deformed so as to contract because the repulsive force of the protruding portion is large. . On the other hand, among the elastic bodies 40 of the buffer plate 30, the elastic bodies 40 arranged at the recessed portions 15 </ b> B of the top plate 15 hardly shrink because the repulsive force of the recessed portions 15 </ b> B is small. Thus, the upper surface of the buffer plate 30 disposed on the storage material 10A is made substantially horizontal by the deformation of the elastic body 40 disposed at the protruding portion 15A of the top plate 15 in the storage material 10A. Can do. Since the upper surface of the buffer plate 30 is substantially horizontal, when a load is applied to the buffer plate 30, the load can be uniformly distributed. In addition, it is preferable that the elastic body 40 of the buffer plate 30 has elasticity so that the upper surface of the buffer plate 30 can be substantially horizontal even when unevenness occurs in the pit 5.

  Thus, in this embodiment, as shown in FIG. 1, the storage and penetration tank 1 </ b> A includes a storage material 10 </ b> A that can store water, and a buffer plate 30 that is disposed on the storage material 10 </ b> A and has water permeability. I have. Thus, since the buffer plate 30 is disposed on the storage material 10A, when a large concentrated load is applied from above, the concentrated load can be dispersed by the buffer plate 30 and a large force is exerted on the storage material 10A. Can be prevented. Since the buffer plate 30 has water permeability, rainwater that has permeated from the ground surface through the buffer plate 30 can be introduced into the storage material 10A.

  Further, as shown in FIG. 3, the buffer plate 30 of the present embodiment has an elastic body 40, and the elastic body 40 is in indirect contact with the storage material 10 </ b> A through the sheet 2. Accordingly, as shown in FIG. 5, when the upper surface of the storage material 10 </ b> A is inclined from the horizontal plane due to unevenness in the pit 5, the elastic body 40 is elastically deformed so as to cancel the inclination, thereby the buffer plate 30. The upper surface of can be made substantially horizontal. Therefore, it is possible to prevent the buffer plate 30 and the storage material 10A from being in contact uniformly and uniformly and applying a large load locally to a part of the storage material 10A. Further, the elastic body 40 of the buffer plate 30 can suppress an impact load from being applied to the storage material 10A. Therefore, it is possible to prevent the storage material 10A from being deformed or broken.

  Further, in the present embodiment, as shown in FIG. 1, the plurality of storage materials 10A are arranged side by side, and the buffer plate 30 is arranged on the plurality of storage materials 10A. By arranging the plurality of storage materials 10A so as to be arranged side by side, there is a great influence when unevenness occurs in the pit 5, and the storage materials 10A are not easily aligned as shown in FIG. If a concrete buffer plate is disposed on the storage material 10A, a space is originally created at a location where the buffer plate and the storage material 10A should contact each other via the sheet 2, and the buffer plate is uniform with respect to the storage material 10A. There is a risk of not touching. However, as in the present embodiment, the buffer plate 30 includes the elastic body 40, so that the space is not created by the deformation of the elastic body 40, and the elastic body 40 of the buffer plate 30 is indirectly attached to the storage material 10A. Contact uniformly. As a result, the load applied to the storage material 10A can be favorably dispersed. Further, even if the storage material 10A is slightly inclined, the elastic body 40 is deformed, whereby the buffer plate 30 can be kept horizontal, and the buffer plate 30 can suitably receive a load from the ground surface.

  In the present embodiment, the plurality of storage materials 10A are stacked and arranged so as to be vertically aligned, and the buffer plate 30 is disposed on the storage material 10A disposed on the top of the plurality of storage materials 10A. ing. Since the plurality of storage materials 10A are stacked and arranged so as to be vertically arranged, if there is unevenness in the pit 5, the storage materials 10A are not properly overlapped with each other. It becomes difficult for the storage materials 10A to be aligned. However, when the buffer plate 30 includes the elastic body 40, the elastic body 40 is deformed, so that the elastic body 40 of the buffer plate 30 and the storage material 10 </ b> A are indirectly in contact with each other. As a result, the load applied to the storage material 10A can be favorably dispersed.

  The plurality of storage materials 10A of the present embodiment are made of a resin material. The storage material 10A made of a resin material is easily deformed when a load is applied. However, since the buffer plate 30 is disposed on the plurality of storage materials 10 </ b> A, the load applied to the storage material 10 </ b> A can be dispersed by the buffer plate 30.

Therefore, when a concentrated load is applied from the ground surface, the load applied to the storage material 10A can be suitably dispersed. In addition, since the base plate 36 has a plurality of water permeable holes 38, the rain water can be introduced into the storage material 10 </ b> A by passing the rain water through the plurality of water permeable holes 38 of the base plate 36.

  In the present embodiment, the buffer plate 30 is made of a resin material. The buffer plate 30 of the present embodiment is lightweight unlike the buffer plate made of concrete.
