Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rainwater inspection basin installed in a roadside ditch to collect road surface water, residential drainage, etc.

[Conventional technology]

As a collection and drainage system in urban areas, water collection basins are installed at various locations below roadside gutters to collect road surface water and drainage water from residential areas, and then discharge it into sewer pipes. . Conventionally, as shown in FIG. 3, the water collection basin used for this purpose has a concrete basin body 1 provided below the side ditch 4 of the road, etc., and communicating with the inlet opening 5 of the street ditch 4. The inflow opening 5 is provided with a cover plate 7 having a removable grating 6, and the basin body 1 has a structure in which an inflow pipe 2 for residential land drainage etc. and a discharge pipe 3 connected to a sewage pipe are provided. It's summery.

[The problem that the idea aims to solve]

In the above-mentioned water collection basin, rainwater collected from the ground such as roads in the side gutter 4 is allowed to flow into the basin main body 1 via the grating 6, and residential drainage is also taken in and discharged to the sewer pipe. There is. However, what flows in from the ground is not only rainwater but also various miscellaneous things such as dust, paper pieces, dead leaves, etc. The grating 6 plays a role in blocking large inflows, but small and medium inflows are , flows through the openings of the grating 6, accumulates on the bottom of the cell body 1, and solidifies. Furthermore, the residential wastewater that enters through the inflow pipe 2 contains a lot of domestic sewage, which mixes with sediment and produces a bad odor. Therefore, it is necessary to remove the sediment from time to time to prevent it from increasing, but this work is very troublesome and requires a lot of effort, so it is often neglected. The capacity of the basin decreases, clogging the drain pipe and collecting
There is a problem that not only the drainage function is deteriorated but also bad odor is emitted through the grating 6, and a solution to this problem has been desired.

The present invention solves these problems with conventional water collection basins, and creates a rainwater inspection basin for collecting and draining water that can easily remove deposits inside the basin and prevent the release of bad odors. This is what we are trying to provide.

[Means to solve the problem]

Next, the configuration of the present invention will be explained with reference to FIGS. 1 and 2, which correspond to embodiments. A basin main body 1 is installed, and a cover plate 7 having an opening 8 is removably placed on the drainage opening 5, and the opening 8 has an open upper end and a flow opening 13 on the side. , 13, a water-sealing box 10 with a cylindrical inlet pipe 15 arranged therein is removably suspended, and a grating 6 is removably mounted thereon.

〔Example〕

Examples of the present invention will be described below in Figures 1 and 2.
This will be explained with reference to the figures.

In the figure, reference numeral 1 denotes a box-shaped concrete basin body with an open upper end, to which an inlet pipe 2 for drainage from residential land is connected to the upper part, and a drain pipe 3 to the lower part. And this box body 1
is buried in the ground with its upper end in contact with a drainage opening 5 provided in the road gutter 4. A cover plate 7 made of concrete is removably placed on the drainage opening 5 of the side gutter 4, and the cover plate 7 is provided with an opening 8 having a square planar shape, and a shelf 9 is formed at the bottom of the opening 8. has been done. Inside this opening 8 is a water sealing box 10.
A grating 6 formed into a rectangular lattice frame in plan view is removably fitted and suspended through the grating 6 .

The water-sealing box 10 is formed in the shape of a vertically long cylinder with a bottom, and has a flange 11 protruding outwardly at its upper end to hang on the shelf 9 of the lid plate 7, and a flange 11 protruding inwardly at the middle part. A flange 12 is provided, and flow ports 13, 13 are provided below the flange 12. and,
Inside this water-sealing box 10, there is a flange 12 that protrudes inward.
A cylindrical introduction tube 15 having a flange 14 at the upper end that is engaged with the flange 12 is detachably arranged.
It is formed in such a length that it is located below the lower edge of No. 3.

The rainwater inspection basin of the present invention is constructed as described above, and the water sealing box 1 is placed in the opening 8 of the cover plate 7 of the gutter 4.
0 is inserted, its flange 11 is locked and attached to the shelf 9, and the grating 6 is fitted and placed in the opening 8 above it. Residential wastewater flows into the basin body 1 from the inflow pipe 2, and rainwater on the ground flows from the side gutter 4 through the grating 6 to the water sealing box 10.
After passing through, it flows into the basin body 1. Rainwater, etc. that entered through the grating 6 flows into the water sealing box 10 from the introduction pipe 15, and as the water level rises, the water flows through the distribution port 1.
3 and 13 and flows into the basin body 1. At that time, the lower end of the introduction pipe 15 is connected to the flow port 13.
Since it is located below the lower edge of the water-sealing box, rainwater, etc. is always stored up to the lower edge of the flow port 13.
The lower part of the introduction pipe 15 is immersed in the rainwater, and a water sealing effect is produced there. In addition, since the earth and sand that flowed in with the rainwater are heavy, they accumulate at the bottom of the water-sealing box 10, and only the rainwater flows out, thereby preventing the earth and sand from flowing into the basin body 1. The odor of the residential wastewater entering from the inflow pipe 2 is prevented from being emitted to the ground through the grating due to the water sealing effect of the water seal box 10.

Therefore, the flow inside the basin body 1 is not obstructed by deposits such as earth and sand, and there is no fear that bad odors will emanate from within the basin body 1. When the accumulation of earth and sand increases in the water sealing box 10, the grating 6 can be removed, the water sealing box 10 can be pulled up to discard the earth and sand, and then it can be reattached and used.

[Effect of idea]

As explained above, the rainwater inspection basin of the present invention is
A basin body in which an inflow pipe and a discharge pipe are connected is provided below the drainage opening of the side gutter, and a lid plate with an opening is removably placed on the drainage opening, and a The top end is open, a flow port is provided on the side, a water seal box with a cylindrical introduction pipe inside is removably suspended, and a grating is removably placed on top of it. Rainwater flowing through the grating passes through the water-sealing box and enters the main body of the trench, so dirt, etc. contained in the rainwater is trapped in the water-sealing box and is prevented from accumulating inside the trench.
Rainwater from the ground and residential land drainage from the inflow pipe can be smoothly discharged from the main body of the basin to the sewage pipe, and the collection and drainage function can be maintained in good condition. Even if sewage flows in and produces a bad odor, the odor will not be released to the ground due to the water sealing effect of the rainwater accumulated in the water seal box. In addition, even if dirt, etc. flows into and accumulates in the water sealing box, the water sealing box is smaller and lighter than the main body of the basin, and is removable, so it has many advantages, such as making it easy to remove the dirt. It is something.
