Description

[Detailed description of the invention] The present invention makes it possible to easily drain rainwater and other sewage into the water collection basin by attaching a water guide raft that receives the drainage hole from below to the lower surface of the lid main body that has a drainage hole. The present invention relates to a lid body for a water collection tank that can completely prevent odor inside the water collection tank from being released into the atmosphere from a drainage hole in the lid itself.

In conventional drainage facilities, which have catchment basins installed on the side of roads or within building sites for the purpose of removing sewage such as rainwater, odors within the catchment basin are released into the atmosphere through the drainage holes in the lid, which is not desirable from the standpoint of environmental hygiene.

The purpose of the present invention is to provide a lid for a water collection basin that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

In Figs. 1 to 3, a water collection basin lid body (hereinafter referred to as a lid body) 1 of the present invention is designed to direct water to the lower surface of a lid main body 3 that closes a water collection basin 2 installed on the side of a road, for example. 4 is attached.

The lid main body 3 is formed into a rectangular plate shape made of concrete, and a drainage hole 6 is cut out approximately in the center of one longitudinal side 5 of the lid main body 3.

The water guide casing 4 is open at its upper and lower ends, and is entirely formed of a flexible sheet material, such as waterproof cloth or a synthetic resin sheet. The upper end opening 4a of the water guide pipe 4 is opened in a rectangular shape, and fixing pieces 9, 9, 9 with through holes 7 arranged in parallel are provided on three side edges thereof, and the other side edge is folded back. A reinforcing core wire 10 is housed in the section. In addition, the distance between the opposing surfaces 11 and 12 of the water guide casing 4 becomes narrower toward the bottom, and in the lower portion 13, the opposing surfaces 11 and 12 are formed in close contact with each other so as to seal the lower end opening 4b. has been done.

The water guide tube 4 formed in this way has a core wire 10
The fixing pieces 9, 9, 9 are attached to the lid so that the side edge 15 where the water is stored is substantially aligned with the lower edge of the longitudinal side 5 of the lid main body 3, and the upper end opening 4a receives the drain hole 6 from below. It is attached to the lid main body 3 by adhering to the lower surface 16 of the main body 3. Note that since the fixing pieces 9, 9, and 9 are provided with the through holes 7, the adhesive can be held well.

However, when the water collection basin 2 is closed with the lid 1 of the present invention as shown in FIG. Rainwater, mud, etc. that have entered the basin 4 are easily discharged into the water collection basin 2 through the lower end opening 4b. On the other hand, in the non-draining state, as shown by the dashed line in the same figure, the facing surface 1 of the water guiding cascade 4
1 and 12 are brought into close contact with each other to seal the lower end opening 4b.
As a result, there is no possibility that the odor in the water collection basin 2 will be dissipated into the atmosphere from the drainage hole 6.

Figure 4 shows the water guide casing 4, upper casing 17 and bottom casing 1.
Another embodiment of the lid body 1 of the present invention is shown, which is constructed from the following. The upper casing 17 has a rectangular cylindrical shape in which the upper and lower end openings are rectangular and the distance between the opposing surfaces 20 and 21 becomes narrower as it goes downward. A flange 22 is provided which is brought into contact with the lower surface of the main body 3 and fixed by adhesives, screws, etc. Furthermore, top 1
7 is made of hard synthetic resin such as vinyl chloride. The lower rafter 19 is formed in substantially the same manner as the water guiding raft shown in the above embodiment, and the upper end inner surface 2
3 is adhered to the outer circumferential surface 25 of the lower end of the upper ridge 17. When the water guide cascade 4 is formed in this manner, the upper part of the water guide cascade 4 maintains a fixed shape, so that the water guide cascade 4 can be easily attached to the lid main body 3.

As mentioned above, the lid body of the present invention has a structure in which a water guiding pipe is attached to the bottom surface of the lid body that closes the water collection basin so as to receive the drainage hole of the lid body from below, and as a result, sewage such as rainwater is collected. While it can be easily drained into the water tank, the odor inside the water collection tank can be completely prevented from being dissipated into the atmosphere through the drainage hole in the lid, contributing to improved environmental hygiene.
