Modularized accumulated water drainage device for drainage and backfill layers of same layer

Abstract

The invention discloses a modularized accumulated water drainage device for drainage and backfill layers of same layer. The device comprises drainage plates and drainage pipes. A cavity is arranged in each drainage plate. The upper and the lower surfaces of each drainage plate are provided with water inlet holes communicated with the cavity. Lateral surfaces of each drainage plate are provided with water drainage holes communicated with the cavity. The drainage pipes are inserted in the water drainage holes. A plurality of drainage plates are connected with each other through the drainage pipes. Two ends of each drainage pipe are inserted into the water drainage holes of one drainage plate. The most marginal drainage pipe is connected with an indoor or outdoor downpipe or vertical pipe and can even directly extend out of a wall and be exposed outdoors. The invention adopts a modularized structure, can be flexibly used in floor backfill layers of bathrooms with different layouts and has good adaptability. As the surfaces of the drainage plates are densely provided with water drainage holes, no drainage dead corner exists so that the drainage effect of the backfill layers is greatly improved. In addition, the invention has simple structure, mainly in the shape of a plate, has low manufacturing cost, is very convenient to install and reduces the difficulty of construction.

Description

1. Technical field [0001] The invention relates to a same-floor drainage system of a toilet, in particular to a device for removing accumulated water in a backfill layer in the same-floor drainage system. 2. Background technology [0002] Existing buildings are equipped with sewage discharge devices, especially in toilets, but the widely used sewage discharge devices cannot meet the national standard for laying drainage branch pipes in this floor, and holes must be drilled on the floor during installation , Install the sewage discharge pipes of this floor on the top of the bathroom on the next floor. The exposed hanging pipes are not only prone to aging and dripping, but also affect the appearance of the toilets of the residents on the lower floor. [0003] In response to these defects, the applicant once proposed a Chinese invention patent application with the application number 200610096701.5, named "Same Floor Drainage System". The drainage components and pipelines in thi...

AI Technical Summary

Problems solved by technology

But because there is only one drainage pipe 10, even if a plurality of drainage pipes are installed radially, the drainage area is also very limited. Since the area of ​​the backfill layer controlled by a single drainage pipe is fan-shaped, the farther away from the area of ​​the shell 1, the drainage pipe needs The larger the controlled area, the greater the drainage effect will be.

In addition, the structure of the shell 1, the inner tube 2, the upper interface 6 and the lower interface 7 is relatively large, which is not very convenient for installation
