Description

  The present invention relates to a seepage trough that temporarily stores rainwater and allows the stored rainwater to penetrate into the ground and discharge it.

  Most of this type of penetrating bowl is made of concrete, but as disclosed in, for example, Patent Document 1 or Patent Document 2, synthetic resin is also proposed. In Patent Document 1, by forming the bottom wall and / or side wall of the bag main body with an expansion plate of a glass fiber reinforced polyolefin stampable sheet having water permeability, the water permeability of the bottom wall and the side wall is set to an appropriate amount, It is disclosed to reduce the weight. Patent Document 2 discloses that a synthetic resin face plate member and a side plate member are coupled by concave-convex fitting so that they are transported in a non-bulky manner to reduce transportation costs. .

  In general, the permeation dredging such as the above-mentioned rainwater permeation dredging, rainwater storage / storage permeation dredging, etc. is buried in the ground in a state in which the surroundings are filled with crushed stones in order to facilitate the penetration of rainwater into the ground. However, it is very difficult to confirm the state of the crushed stone after the penetration basin is installed, and it is very difficult to identify the cause and recover the ability when the capacity of the penetration jar is excessive or insufficient.

On the other hand, for example, a penetrating dredger that is installed without being filled with crushed stone, such as a rainwater storage penetrating tank described in Patent Document 3, has been proposed. The rainwater storage and penetration tank is configured by filling a permeable bag with a recycled rubber filler and temporarily stores rainwater in the permeable bag.

  By the way, the said water-permeable bag is made into the three-dimensional bag by sewing the sheet material which has water permeability. Therefore, it is inferred that it is possible to accommodate the penetrating soot disclosed in Patent Document 1 and / or Patent Document 2, and if the water-permeable bag is used in this way, the penetrating soot can be installed without filling the crushed stone. It is considered possible. Alternatively, it is considered that the osmosis can be installed without filling the crushed stone even if a sheet material having a large water permeability is used as a furoshiki so as to wrap the entire osmosis.

  However, there is a problem that the inside of the hole excavated in the ground for installing the penetration rod is narrow, and the installation work of wrapping the sheet with the sheet material while assembling the penetration rod in the hole is extremely complicated. With respect to this problem, it is considered that the installation work can be easily performed by assembling the osmosis pouch outside the hole and wrapping it with a sheet material and then housing the osmosis peg in the hole. However, in such a case, there is a problem that there is no way of confirming the state of the permeation flaw inside the sheet material, and the fitting of the face plate member and the side plate member is disengaged when accommodated in the hole. It becomes difficult to find defects. Furthermore, it is difficult to wrap up the entire surface of a large permeation bag with a single sheet material, which is a troublesome operation.

  The present invention has been made paying attention to such problems existing in the prior art. The purpose is to provide a penetrating bowl that can be easily installed.

Next, a method for installing the penetrating rod 10 will be described.
When installing the penetrating rod 10, first, the bottom member 18 is laid on the bottom of the excavated hole, and the bottom plate 15 is placed on the bottom member 18 to determine the installation position of the penetrating rod 10. Further, outside the hole, the side plate members 16 are connected in advance, the side plate covering member 19 is wound around the outer surface, and the folded portion 31 of the side plate covering member 19 is folded back to the inner surface of the side plate 16a. Thereafter, the side plate member 16 covered with the side plate covering member 19 is connected to the bottom plate 15 so as to cover the bottom plate 15 from above. When the side plate member 16 and the bottom plate 15 are connected, the lower end portion of the side plate covering member 19 is fixed. Then, after the top plate 17 is connected to the side plate member 16 and the upper end portion of the side plate covering member 19 is fixed, the filter cage 37, the conduit connection tube 33, and the adjuster 34 are inserted into the water guide holes 29 of the top plate 17. Then, the lid 35 is sequentially attached, and the hole is backfilled to complete the installation of the penetration rod 10.

  In the installation operation of the penetrating rod 10, the mounting of the side plate covering member 19 is completed by a simple operation of only winding around the outer surface of the side plate member 16. Further, the side plate covering member 19 can be mounted outside the hole, and does not need to be operated in the narrow hole and is easy to perform. Further, in the bottom plate 15, the operation is completed only by being placed on the bottom member 18, and the bottom plate 18 is pressed against the bottom member 18 by earth pressure applied to the main body 11 at the time of backfilling. Fully coated. And since the connection of the side plate member 16 and the bottom plate 15 is performed in the hole, it is reliable. Therefore, the sift main body 11 is surely covered by the covering member 12 while simplifying the installation work, and therefore it is not necessary to fill the surroundings of the coffin main body 11 with crushed stone.

  Moreover, when connecting the vertical pipe member 13 to the water guide hole 29, the top plate 17 tries to bend, but the water guide hole 29 is disposed at the corner of the top plate 17 and is connected to the side plate 16a. Therefore, the weight of the vertical pipe member 13 can be suitably supported by each side plate 16a. For this reason, it is possible to suppress the top plate 17 from being bent by a load such as earth pressure applied to the standing pipe member 13. Therefore, it is not necessary to fill the crushed body 11 with crushed stone. In addition, when the top plate 17 is to be bent not only by earth pressure but also by passers-by, passing vehicles, etc., a bar for supporting the top plate 17 inside the hollow main body 11 is provided. It is also possible to stand upright. Further, since the water guide holes 29 are disposed at the corners (peripheral edges) of the top plate 17, the position of the water guide holes 29 is changed by changing the direction in which the top plate 17 is connected to the side plate member 16. It is also possible to change. As a result, it is possible to easily change the position of the water conduit connecting cylinder 33 connected to the water conduit 29 according to the arrangement of the water conduit 36.

  In addition, although it was set as the structure which coat | covers the outer surface of the cocoon main body 11 with the coating | coated member 12, in the said penetration ridge 10, it is good also as a structure which coat | covers the inner surface of the cocoon main body 11 with the coating | coated member 12.
