Three-stage filtering environment-friendly gutter inlet

Abstract

The invention relates to a three-stage filtering environment-friendly gutter inlet. The gutter inlet comprises a rainwater grate, a grid basket sewage intercepting groove, and a rainwater settling area; the rainwater grate is located at the inlet of the top of a gutter inlet body and flush with a road surface; the grid basket sewage intercepting groove is located under the rainwater grate; the rainwater settling area is located in the bottom area of the gutter inlet body; an overflow filtering area is arranged in the center of the rainwater settling area and provided with an overflow filteringhead and an overflow vertical pipe; the overflow vertical pipe penetrates through the bottom of the gutter inlet body through an embedded sleeve and is perpendicular to the gutter inlet body; the upper end of the overflow vertical pipe is connected with the overflow filtering head; and the lower end of the overflow vertical pipe is connected with a discharge pipeline at the bottom of the gutter inlet body through a bent head. The three-stage filtering environment-friendly gutter inlet solves the problems that a traditional gutter inlet is poor in interception and filtration, and a pipeline isprone to blockage, pollutants can be effectively prevented from entering a drainage system, the pipeline blockage probability is reduced, and the gutter inlet is simple in structure, low in cost, easy to manufacture and install and capable of being popularized.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and relates to an environment-friendly rainwater outlet with three-stage filtration, in particular to an environment-friendly pavement rainwater collection and discharge device with three-stage filtration, sand settling and deodorization functions. Background technique [0002] In recent years, frequent urban waterlogging disasters have brought a lot of inconvenience to people's production and life. As the most commonly used auxiliary structure of urban road drainage system, the design and selection of gully is very important for rainwater collection and discharge. [0003] Traditional gullies usually use rainwater grates to collect ground rainwater and then flow it into rainwater pipes. However, the rainwater is often mixed with road garbage such as fallen leaves, fruit cores, sediment, and plastic bags. lead to urban flooding. In addition, garbage is mixed into the pipeline and rainwater ...

Problems solved by technology

[0003] Traditional gullies usually use rainwater grates to collect ground rainwater and then flow it into rainwater pipes. However, the rainwater is often mixed with road garbage such as fallen leaves, fruit cores, sediment, and plastic bags. causing urban flooding

And garbage mixed into the pipes and rainwater deposits and rots, forming various gases such as hydrogen sulfide, and the odor will overflow through the rainwater outlet, seriously endangering the health of the surrounding people

[0004] At present, although some gully designs with garbage filtering effect and anti-odor effect have appeared, most of them have complex structures and high costs, so it is difficult to be popularized and applied
