Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a drainage basin device for connecting a plurality of drainage branch pipes in a residential area to one drainage basin.

(Conventional technology) Conventionally, a drainage basin installed in a residential area uses a basin body formed of large-sized concrete having a diameter of 300 mm or more or a basin body formed of a synthetic resin such as a polypropylene resin. . However, recently, there has been a remarkable tendency for residential land to be narrowed, and the space in which drainage pipes are buried has become narrow, and in many cases, large drainage basins cannot be installed.

Almost all drainage pipes in residential lands are made of vinyl chloride resin pipes, which cannot be bonded to concrete or polypropylene resin box bodies, and cannot be used with mortar or special mortar. Connected with a bonding agent. However, in such a structure in which a vinyl chloride resin tube is connected to a concrete or polypropylene resin box body using mortar or a special bonding agent, the joints are likely to peel off due to fluctuations in the ground, etc. There is a problem that infiltrated water such as water may enter the main body of the basin, and the infiltrated water flows into the sewage treatment plant, thereby increasing a useless load on the treatment plant.

(Problems to be solved by the present invention) The above-mentioned conventional large-sized basin has problems that it is difficult to install it in a narrow residential area and that it is difficult to connect a vinyl chloride resin pipe. doing.

Therefore, recently, a small drainage basin body formed of a vinyl chloride resin has become widespread.

However, in the conventional small drainage basin main body, the connection port of the drainage branch pipe is provided only in one place, and the basin body must be installed for each drainage branch pipe, and a plurality of adjacent drainage branch pipes are required. In the case where there is, a plurality of square bodies must be installed, which increases the installation space, and further increases the material cost and the construction cost.

It is also conceivable to form a connection port for multiple drainage branch pipes in the body of a small drainage basin.However, a mold is required according to the number of drainage branch pipes, which is not only expensive but also versatile. Has a lacking problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a plurality of drainage branch pipes can be connected to a small drainage basin main body, which can be easily installed even in a narrow residential area, and can be obtained at a low cost. The purpose is to provide.
