Drain moisture from drain holes and outlets.

  However, in the above-described conventional technology, that is, when the nonwoven fabric filter is pushed out and ruptured, the debris flows to the drainage hole through the water inlet, and the soil behind the retaining wall becomes hollow and the retaining wall collapses. Invited. Therefore, the present inventor considered that the above-described drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems with a rational design.

  The present invention has been made to solve the above-described problems of the prior art. That is, an object of the present invention is to provide a drainage device provided on a retaining wall.

  In order to solve the above problems and achieve the object, a drainage device according to the present invention includes a drainer and a filter plate. The drainage device has a hollow cylindrical body having drain holes and a lid body connected to the hollow cylindrical body and having a plurality of water inlets. The filter plate is installed in the drainage device, has a plurality of filter ports, and has a storage space communicating with the plurality of water intake ports, the plurality of filter ports, and the drain holes between the lid.

  In the present invention, when the drainage device is provided in the drainage hole of the retaining wall by the storage space between the lid and the filter plate, the stones placed in the storage space are crushed stone and dust in the filtration port and the drainage hole. In addition to being able to block entry, excess water can be effectively filtered and water can be discharged from the filter port, drain hole, and drain hole of the filter plate.

(One embodiment)
Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims of utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. A drainage device 100 according to an embodiment of the present invention is provided on a retaining wall, and includes a drainage device 110 and a filter plate 120. The drainage device 110 has a hollow cylindrical body 111 and a lid body connected to the hollow cylindrical body 111. 115, the hollow cylindrical body 111 has a drain hole 112, and the lid body 115 has a plurality of water inlets 116 (see FIGS. 1, 2, and 3). In the present embodiment, the lid body 115 is integrally formed into a hollow cylindrical body 111, the filter plate 120 is installed in the drainer 110, the filter plate 120 has a plurality of filter ports 121, and the filter plate 120 and the cover body There is a storage space S between 115, and the storage space S communicates with a plurality of water inlets 116, and the plurality of filter ports 121 and drain holes 112 are the drainage holes of the hollow cylindrical body 111 in this embodiment. Coupled to the holes 112 or, in another embodiment, the filter plate 120 is coupled within the lid 115.

According to FIGS. 1, 2, 3, and 4, the drain hole 112 of the hollow cylindrical body 111 includes a wall portion 113 and a first position limiting portion 114 installed in the wall portion 113. The filter plate has a second position limiting portion whose position is limited to the first position limiting portion.
In the present embodiment, the first position limiting portion is recessed in the recessed portion of the wall portion 113, the second position limiting portion is protruded in the rib portion of the filter plate 120, and the second position limiting portion 122 (rib portion). ) Is fitted in the first position limiting portion (concave portion), and the filter plate 120 is limited to the drain hole 112 of the hollow cylindrical body 111 (see FIGS. 1, 2, 3 and 4).

  4 and 5 are schematic views showing the drainage device 100 provided on the retaining wall W. FIG. The hollow cylindrical body 111 of the drainage device 110 has a separate engaging portion 111a. When the hollow cylindrical body 111 is provided in the drainage hole A of the retaining wall W, the engaging portion 111a is locked to the wall portion of the drainage hole A. Provided. In the present invention, the filter medium B is placed in the storage space S between the lid 115 and the filter plate 120. The filter medium B may be stone, and the filter medium B (stone) placed in the storage space S is soiled. The crushed stone and dust of C can be blocked from entering the filter port 121 and the drain hole A, and excess moisture is filtered to drain the moisture from the filter port 121, the drain hole 112, and the drain hole A of the filter plate 120. It is possible to effectively prevent the retaining wall W from collapsing.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
