Description

  The present invention relates to a storage / drainage block and a storage / drainage structure for improving drainage of the ground.

  In facilities such as golf courses, parks, various ball game fields, or farmland, etc., there is a case where a culvert drainage facility that adjusts the amount of pore water in the ground to improve water drainage on the ground surface is provided. As a typical example of the above culvert drainage facility, for example, as disclosed in Patent Document 1 below, a plurality of culvert drainage pipes are embedded in a predetermined ground, and excess water in the ground is excluded to the outside by the culvert drainage pipe. Technology to do is known.

  Further, as a different technique for improving water drainage on the ground surface, Patent Document 2 listed below forms a laminated structure by laminating a plurality of concave and convex resin plates on which a plurality of hollow convex portions are formed, and at least a part thereof is water permeable. There has been proposed a drainage material that is housed in a cylindrical body provided with. The concavo-convex resin plate, which is a plate-like member, has a plurality of convex portions that project in a direction orthogonal to the surface direction. Such a drainage material is laminated such that the convex portions of one concave-convex resin plate do not enter the concave portions or the hollow convex portions between the convex portions of the other concave-convex resin plate facing each other. A space between the resin plates is secured.

Japanese Patent Laid-Open No. 11-46605 JP 2009-972425 A

However, both the underdrainage facility disclosed in Patent Document 1 and the drainage material disclosed in Patent Document 2 have problems.
That is, the underdrainage facility needs to dig up the ground surface extensively and embed a large amount of pipes and the like. For this reason, the facility has a problem that it takes a lot of time to install, and in order to promote drainage by selectively installing it in a specific place where water pools are easy to collect, such as a ground depression or a golf bunker. It was practically unsuitable. In addition, there has been a problem that earth and sand enter a hole formed in a culvert drainage pipe used in a culvert drainage facility and clog it, and the drainage function tends to deteriorate.

  Further, the drainage material formed by laminating a plurality of concave and convex resin plates needs to install the plate-like member substantially flat in order to maintain the space secured inside. Therefore, when installing the drainage material, a process of digging up the ground and leveling the ground contact surface is required, which takes time for installation. The drainage material has the following problems although the entire laminated structure is accommodated in a cylindrical body having water permeability, so that earth and sand are prevented from entering the inside and causing clogging. That is, in the drainage material, the concave portion (space) is open toward the ground on the side surface of the laminated structure of the uneven resin plate, and is weak against the force from the horizontal direction. There was a risk of breaking through the body and entering the recess (space). And if a part of cylindrical body which covers the whole laminated structure is torn, while the inflow of earth and sand will continue, a tear will spread from there and there exists a possibility that a drainage function may be lost substantially.

The present invention has been made in view of the above-described problems. That is, the present invention has a simple structure, can easily improve drainage regardless of the size of the installation area from a wide area of ground to a locally selected ground, and is well clogged with earth and sand. Provided is a block for stored drainage.
In addition, the present invention provides a storage and drainage structure that is easy to construct regardless of the size of the construction area, that can shorten the construction time compared to the prior art, and that has a high sustainability of the storage and drainage function. is there.

  The storage drainage block of the present invention has a hollow polyhedron block having a side surface made of a resin plate and having a hollow portion therein, and a water permeable member covering the entire periphery of the hollow polyhedron block, and the resin plate is It has a plurality of holes penetrating in the thickness direction.

  The storage / drainage structure of the present invention is characterized in that a plurality of the blocks for storage / drainage of the present invention are embedded in the ground.

  The storage drainage block of the present invention has a simple structure mainly composed of a hollow polyhedron block composed of a resin plate having a plurality of holes penetrating in the thickness direction and a water-permeable member covering the block. The storage drainage block having a simple structure is embedded in the excavated ground, so that a space for temporarily storing pore water in the ground can be secured. The number and area of hollow polyhedral blocks to be embedded can be determined as appropriate in consideration of the ground environment, etc., so that it is easy to improve the water drainage of the ground regardless of the size of the ground area where improvement of water drainage is required. Can do. Moreover, since the hollow polyhedral block of this invention is covered with the water-permeable member, it is prevented that earth and sand enter the inside. Furthermore, since the hollow polyhedral block has a side surface made of a resin plate and can receive earth pressure from multiple directions, the water-permeable member covering the periphery is not easily damaged by earth pressure. .

  In addition, the storage and drainage structure of the present invention can be implemented simply by digging up a predetermined ground and embedding a plurality of the blocks for storage and drainage of the present invention, and can easily improve drainage of the ground in a short time. . Each of the plurality of storage and drainage blocks used in the storage and drainage structure has a structure in which the water-permeable member is not easily damaged as described above. In addition, even if the water-permeable member is damaged in one storage / drainage block, the damage does not affect other storage / drainage blocks, so the drainage function of the entire storage / drainage structure is good. Maintained. Each of the plurality of storage drainage blocks is independent and has a function of allowing pore water to permeate inside and discharging to the outside. Such a storage drainage block is not subject to any special restrictions on the arrangement relationship with other storage drainage blocks in the ground, and has a special installation direction such as vertical, horizontal, horizontal, etc. There are no restrictions. Therefore, when carrying out the storage and drainage structure of the present invention, after digging up the ground, in order to embed a plurality of blocks for storage and drainage, the process of leveling the ground contact surface can be omitted as appropriate, and the construction time Can be shortened.

<First embodiment>
Below, 1st embodiment of the block for storage drainage of this invention is described using FIGS. 1-3. FIG. 1 is a perspective view showing an example of a storage drainage block 100 according to the first embodiment of the present invention. In FIG. 1, in order to illustrate the hollow polyhedral block 20 provided inside the water permeable member 30, a part of the water permeable member 30 is not illustrated. FIG. 2 is a development view of the hollow polyhedron block 20. 3 is a cross-sectional view taken along the line III-III of the lateral side resin plate 10c shown in FIG.

First, an outline of the storage drainage block 100 will be described.
The storage drainage block 100 includes a hollow polyhedron block 20 having a side surface made of the resin plate 10 and having a hollow portion therein, and a water permeable member 30 that covers the entire periphery of the hollow polyhedron block 20. The resin plate 10 has a plurality of holes 40 penetrating in the thickness direction. Therefore, in a state where the storage drainage block 100 is embedded in the ground, excess pore water in the ground permeates into the storage drainage block 100 (hollow part) through the water permeable member 30 and the hole 40, Stored temporarily. This improves the drainage of the ground. In addition, when the amount of pore water in the ground is reduced, the pore water that has permeated the hollow portion is naturally discharged to the surrounding ground. Thus, the storage / drainage block 100 can repeat the storage and drainage according to the amount of pore water in the surrounding ground.

As described above, the storage drainage block 100 has a very simple structure mainly composed of the hollow polyhedron block 20 and the water permeable member 30, and is easy to handle. It is possible to easily improve the water drainage of the ground by simply excavating the ground where improvement of water drainage is required, forming a hole, placing an appropriate number of storage drainage blocks 100 in the hole, and then backfilling. .
According to the storage drainage block 100, the size of the area from the ground of a wide area to the locally selected ground can be increased or decreased simply by adjusting the area of the ground to be dug up and the number of the storage drainage blocks 100 embedded in the ground. Regardless, it is possible to easily improve drainage.
In addition, for example, in a depression where a puddle tends to generate after rain, the approximate amount of water constituting the puddle is grasped, and the total volume of the hollow portions of the plurality of storage drainage blocks 100 is equal to or greater than the amount of water. By determining the number of the storage drainage blocks 100 embedded in the ground, it is possible to easily prevent the occurrence of water pools. If the improvement of drainage is insufficient when burying several storage / drainage blocks 100 in the ground, the ground may be dug again and an appropriate number of storage / drainage blocks 100 may be added and embedded. .

Next, the details of the storage drainage block 100 will be described.
The hollow polyhedron block 20 used for the storage drainage block 100 is composed of a plurality of resin plates 10. The resin plate 10 in the present embodiment is a substantially flat plate member, and the hollow polyhedron block 20 is a solid formed by using a plurality of the substantially flat resin plates 10. Here, “substantially flat” means not only when one surface and the other surface of the resin plate 10 are completely flat, but either or both surfaces have continuous or discontinuous irregularities. The aspect which is provided and is plate shape as a whole is also included. The dimension and shape of the hollow polyhedron block 20 are not particularly limited. From the viewpoint of easy transportability or handleability, for example, the vertical dimension, horizontal dimension, and depth dimension of the hollow polyhedral block 20 are each preferably in the range of 5 cm to 100 cm, and preferably 10 cm to 80 cm. More preferably, it is the range. At this time, the vertical dimension, the horizontal dimension, and the depth dimension of the hollow polyhedron block 20 may be the same or different.

  For example, the resin plate 10 stands up in a direction in which the surface on one side A1 is substantially flat and the surface on the other side A2 intersects the surface direction of the resin plate 10 as in the lateral side surface resin plate 10c shown in FIG. Ribs 60 may be provided. That is, one or a plurality of concave portions 61 partitioned by the rib 60 may be formed on the surface of the other side A2. By providing the ribs 60 in this way, the strength of the resin plate 10 can be increased. The rib 60 stands, for example, in a direction orthogonal to the surface direction of the resin plate 10.

  In the present embodiment, the resin plate 10 is preferably arranged so that the surface on the one side A1 faces the ground and the surface on the other side A2 provided with the ribs 60 faces the inside of the hollow polyhedral block 20. The surface on which the rib 60 is provided is inward, and the substantially flat surface is outward, thereby increasing the strength of the hollow polyhedron block 20 and covering the hollow polyhedron block 20 when subjected to earth pressure. It is possible to prevent the sexual member 30 from being damaged by being caught on the rib 60. Although the resin which comprises the resin board 10 is not specifically limited, For example, a polypropylene resin, a polyethylene resin, a polystyrene resin, or a polyurethane resin etc. can be mentioned.

The hollow polyhedron block 20 in the present embodiment is a solid composed of a plurality of surfaces. In the present embodiment, each surface constituting the hollow polyhedron block 20 is composed of a single resin plate 10. Thus, each surface is comprised by one member with substantially no joint, and while improving the intensity | strength of the hollow polyhedron block 20, manufacturing cost can be suppressed by simplifying a structure.
As a modified example not shown, some or all of the surfaces constituting the hollow polyhedron block 20 may be composed of a plurality of resin plates 10. In this way, by using a plurality of prescribed resin plates 10 and changing the size and shape of one surface of the hollow polyhedral block 20, it is possible to adapt the shape and volume of one hollow polyhedral block 20 to the ground environment. Easy.

  As shown in FIG. 1, the hollow polyhedron block 20 according to the present embodiment includes an upper surface constituted by the upper surface resin plate 10a and a lower surface constituted by the lower surface resin plate 10b arranged in parallel with a predetermined distance from the upper surface. And a lateral side surface constituted by a plurality of lateral side surface resin plates 10c linking the upper surface and the lower surface. Specifically, as shown in FIG. 2, the hollow polyhedron block 20 is a hexahedron comprising an upper resin plate 10a, a lower resin plate 10b, and four lateral resin plates 10c. When the hexahedron is a cube, for example, as shown in FIG. 2, the upper surface resin plate 10a and the lower surface resin plate 10b are squares having the same area, and the four lateral side resin plates 10c are the length of one side of the square. On the other hand, it is good to make it a rectangle whose width dimension is small by the thickness of the lateral side resin plate 10c.

  As shown in FIG. 2, in the hollow polyhedron block 20, the first resin plate 10 (upper surface resin plate 10a and lower surface resin plate 10b) constituting the upper surface and the lower surface has a recess 70 on the outer edge of the inner surface, The second resin plate 10 (lateral side surface resin plate 10c) that constitutes the upper and lower end surfaces has convex portions 72 corresponding to the concave portions 70. By fitting the convex part 72 to the concave part 70, the three-dimensional hollow polyhedral block 20 can be assembled. More specifically, for example, a convex portion 72 (72a) formed on the lower end surface of one lateral side resin plate 10c is fitted into the concave portion 70 (70a) formed on the lower surface resin plate 10b, and the lower surface resin plate 10b is inserted. The convex part 72 (72b) formed in the lower end surface of the other side surface resin plate 10c is inserted in the formed concave part 70 (70b). Similarly, the protrusion 72 (72c) is inserted into the recess 70 (70c) shown in FIG. 2, and the protrusion 72 (72d) is inserted into the recess 70 (70d). As described above, the concave portion 70 is provided at a predetermined position of the first resin plate 10 and the convex portion 72 corresponding to the concave portion 70 is provided on the second resin plate 10 to employ the concave and convex fitting means for fitting the corresponding concave and convex portions. By doing so, it is possible to easily assemble a solid body having a desired shape including upper and lower surfaces and lateral surfaces. In addition, the inner side surface of the resin board 10 here means the surface on the side facing the inside of the hollow polyhedral block 20.

  However, in the present invention, the means for combining the plurality of resin plates 10 to form the three-dimensional hollow polyhedron block 20 is not limited to the above-described uneven fitting means. For example, one resin plate 10 and another resin plate 10 adjacent thereto may be bonded together with an adhesive member such as an adhesive or an adhesive tape.

  In the present embodiment, from the viewpoint of maintaining the shape of the hollow polyhedron block 20 well, the outer periphery of the hollow polyhedron block 20 is fastened by a long fixing member 50 as shown in FIG. As shown in the drawing, the fixing member 50 may be provided only in one circumferential direction of the hollow polyhedral block 20, or although not shown, the fixing member 50 is wound around intersecting in one circumferential direction and the other circumferential direction. May be attached.

  As described above, in the present embodiment, a plurality of concave portions 70 are provided at predetermined locations on the upper surface resin plate 10a and the lower surface resin plate 10b, and a plurality of convex portions 72 are provided at predetermined positions on the lateral side resin plate 10c. The hollow polyhedron block 20 is assembled by fitting these irregularities. In this aspect, the fitting directions of the plurality of concave portions 70 and the plurality of convex portions 72 corresponding thereto are unified in the vertical direction. Therefore, the hollow polyhedral block 20 is stably held in shape only by being fastened by the fixing member 50 only in one circumferential direction including the upper surface resin plate 10a and the lower surface resin plate 10b.

  The member used as the fixing member 50 is not particularly limited as long as it is wound around the outer periphery of the hollow polyhedron block 20 and can fasten the hollow polyhedron block 20. For example, a string, a resin tape, a binding band, or the like A long member is mentioned. In the present embodiment, the fixing member 50 is provided in direct contact with the outer periphery of the hollow polyhedral block 20, but the hollow polyhedral block 20 may be tightened by the fixing member 50 from above the water-permeable member 30. .

  The water permeable member 30 is a member capable of passing pore water in the ground in the thickness direction. From the viewpoint of easy processing so as to cover the entire periphery of the hollow polyhedron block 20, a sheet-like member is preferable. In this embodiment, the perimeter of the hollow polyhedron block 20 is covered with a water-permeable member 30 formed by forming a water-permeable sheet-like member into a bag shape. The sheet-like member is preferably a porous member having a large number of pores that are difficult for gravel to pass through, and examples thereof include non-woven fabrics and mesh sheets, but are not limited thereto.

<Second embodiment>
Next, a storage drainage block 200 according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view showing an example of a storage drainage block 200 according to the second embodiment of the present invention. In FIG. 4, in order to illustrate the hollow polyhedron block 22 provided inside the water permeable member 30, a part of the water permeable member 30 is not illustrated and the inside of the hollow polyhedron block 22 is illustrated. The lateral side resin plate 10c on the front side of the paper is not shown. FIG. 5 is a perspective view of a resin plate 80 used in the storage / drainage block 200 according to the second embodiment of the present invention.

  The storage drainage block 200 is configured in the same manner as the storage drainage block 100 except that the upper surface resin plate 80a is used instead of the upper surface resin plate 10a and the lower surface resin plate 80b is used instead of the lower surface resin plate 10b. The Further, the upper surface resin plate 80a and the lower surface resin plate 80b are configured in the same manner as the upper surface resin plate 10a and the lower surface resin plate 10b except that the support 82 is provided. Regarding the storage drainage block 200, the configuration similar to the storage drainage block 100 will be described below with reference mainly to the description in the first embodiment as appropriate, and the configuration different from the storage drainage block 100 will be mainly described below.

In the present embodiment, the storage drainage block 200 is disposed on at least one of the two resin plates 80 (upper surface resin plate 80a and lower surface resin plate 80b) facing each other through the hollow portion with respect to the surface direction of the resin plate 80. Posts 82 are formed standing in the intersecting direction. Then, the two resin plates 80 (the upper resin plate 80a and the lower resin plate 80b) facing each other through the support 82 are physically continuous.
For example, as shown in FIG. 4, support columns 82 are provided on both the upper surface resin plate 80a and the lower surface resin plate 80b, and the front end surfaces 85 (see FIG. 5) of the two support columns 82 come into contact with each other. The plate 80a and the lower surface resin plate 80b are physically continuous. Although not shown in the drawings, the support 82 may be provided only on the lower surface resin plate 80b, and the leading end surface 85 of the support 82 may be in contact with the inner surface of the upper surface resin plate 80a, so that both may be physically continuous. In this way, the opposing resin plates 80 are physically continuous by the support columns 82, whereby the strength of the hollow polyhedral block 22 in the continuous direction can be increased.

In the present embodiment, the resin plate 80 used as the upper surface resin plate 80a and the lower surface resin plate 80b includes a column 82 standing upright in a direction perpendicular to the surface direction (surface perpendicular direction) as shown in FIG. Although the illustrated support 82 is one, a plurality of supports 82 may be provided on one resin plate 80.
The inside of the column 82 is hollow, and the weight of the resin plate 80 is reduced. Further, the base end 83 of the support 82 is located in the recess 61 defined by the rib 60, and the base end 83 is opened to form the hole 41. On the other hand, a hole 88 is formed in the distal end surface 85 provided at the distal end facing the base end 83. Thereby, the support | pillar 82 has the hole 41, the inside, and the hole 88 connected, and water permeability is maintained from the base end 83 to the front end surface 85.

The front end surface 85 of the support column 82 is provided with a protrusion 84 that protrudes from the front end surface 85 to the outside of the support column 82 and a fitting portion 86 having a dimension that allows the protrusion 84 to be fitted. Thereby, when the front end surface 85 of the upper surface resin plate 80a and the front end surface 85 of the lower surface resin plate 80b are brought into contact with each other, the protruding portion 84 formed on the upper surface resin plate 80a is replaced with the fitting portion formed on the lower surface resin plate 80b. 86, and the protruding portion 84 formed on the lower surface resin plate 80b is fitted to the fitting portion 86 formed on the upper surface resin plate 80a, so that the contact state can be stably maintained.
Further, when the upper surface resin plate 80a and the lower surface resin plate 80b are brought into contact with each other, the holes 88 provided in the respective front end surfaces 85 may be disposed at positions where they communicate with each other. As a result, as shown in FIG. 4, the space between the hole 41 provided in the upper surface resin plate 80a and the hole 41 provided in the lower surface resin plate 80b can be permeable, and the hollow polyhedron block 22 is also spaced from the inside of the column 82. The strength can be improved while securing a space for temporarily storing water.

<Third embodiment>
Next, an example of the storage and drainage structure 300 of the present invention will be described with reference to FIG. 6 as a third embodiment of the present invention. FIG. 6A is an explanatory view showing an example of a storage drainage structure 300 according to the third embodiment of the present invention, and FIG. 6B is an explanatory view showing a storage drainage structure 310 which is a modification of the third embodiment.

  The storage drainage structure 300 is configured by embedding the above-described storage drainage block 100 in a plurality of grounds. For example, the storage and drainage structure 300 can be configured by digging up a ground of a depression where the water pool 120 is easily formed during rainfall, arranging the storage and drainage blocks 100 in alignment there, and backfilling an appropriate amount of earth and sand. As a result, part or all of the water that has formed the puddle 120 is temporarily stored in the storage / drainage block 100 that constitutes the storage / drainage structure 300, thereby preventing the formation of the puddle 120. it can. Of course, the drainage structure 300 may be provided on the ground where the water pool 120 is easy to be formed, or on a flat ground or a raised ground instead of a depression, so that the ground can be drained regardless of various shapes of the ground surface. Can be improved.

  The plurality of storage drainage blocks 100 are individually independent blocks, and are easy to transport and handle to the place where the storage drainage structure 300 is constructed. Therefore, the storage and drainage structure 300 is required to improve drainage, and is implemented with simple construction in which an appropriate number of storage and drainage blocks 100 are arranged side by side in consideration of the area of the ground and the presence or absence of the formation of the water pool 120. Is done. The pore water temporarily stored in the storage / drainage block 100 in the storage / drainage structure 300 is naturally drained from the inside of the block to the surrounding ground as the amount of pore water in the surrounding ground decreases. Thereby, the inside of the block 100 for stored drainage becomes a hollow part again. Thus, the storage and drainage structure 300 including a plurality of storage and drainage blocks 100 repeats storage and drainage.

  The storage / drainage structure 310 which is a modification shown in FIG. 6B is a storage / drainage structure 310 formed by digging up the ground, randomly arranging an appropriate number of storage / drainage blocks 100 therein, and backfilling an appropriate amount of earth and sand. Can be configured. That is, the plurality of storage drainage blocks 100 are independent of each other and have a function of allowing pore water to permeate inside and discharging to the outside. Therefore, the storage / drainage structure 310 is not particularly restricted in the arrangement relationship between one storage / drainage block 100 and the other storage / drainage block 100, and is also subject to special restrictions in the installation direction such as up / down / left / right horizontality. The above-described storage and drainage can be repeated without any problems. That is, the storage drainage structure 310 digs up the ground to form a hole, and appropriately omits the step of leveling the ground contact surface, and then randomly places a plurality of storage drainage blocks 100 in the hole, It can be carried out with simple and short-time construction just by backfilling with. For example, a ground such as a ground, a facility such as a park or a golf course, or a ground such as farmland where a building is constructed on the ground or a vehicle or the like frequently passes has a small load burden from above. Therefore, even if the plurality of storage and drainage blocks 100 embedded in the ground under such an environment are not strictly arranged, there is no possibility of being crushed by a load from above. Therefore, it is particularly preferable to implement the storage and drainage structure 310 that can be carried out easily and in a short time on the ground under such an environment and that has a good drainage effect.

  The storage drainage structures 300 and 310 described in the present embodiment are examples using the storage drainage block 100, but the storage drainage block 200 may be used instead of the storage drainage block 100. The storage drainage block 100 and the storage drainage block 200 may be mixed and used. The plurality of storage drainage blocks 100 used in the storage drainage structures 300 and 310 may be unified in the same shape and the same size, or may be mixed in different shapes or different sizes. The storage and drainage structures 300 and 310 can be implemented in a ground such as a golf course, a park, various facilities such as a ball game field, or an arbitrary environment such as farmland.
