Prefabricated well with interceptor

Abstract

The invention discloses a prefabricated well with an interceptor, wherein the prefabricated well is pressed by a polypropylene material for one time; four support arms oppositely extend at the upper part of the inner wall of a well chamber; bayonets are arranged on the support arms and are mutually embedded together with lug bosses of an extension arm of an interceptor fixing frame; a separator is arranged in the middle of the interceptor fixing frame; the prefabricated well also comprises a storm-water inlet joint water intake grate; and a tiled type water intake grate is embedded into a vertical type water intake grate to integrally form an L-shaped joint water intake grate. The invention has the advantages that the prefabricated well adopts the polypropylene material, is low in cost, convenient to promote and popularize, simple in structure, simple, convenient and fast to construct and install.

Description

technical field [0001] The invention relates to a rainwater intercepting device, in particular to a prefabricated well with an interceptor. Background technique [0002] There are often two problems in underground rainwater pipelines: 1. After the rainwater carries a large amount of solid waste such as leaves, garbage, and mud and sand through the rainwater outlet, it flows directly into the drainage pipe of the drainage diversion pipe or the confluence pipe through the connecting pipe. A large amount of sludge deposits will be produced in the sediment tanks and pipes of the well together with the sundries in the domestic rainwater. Although some of these sludge will be taken out during the maintenance of the drainage pipes, most of them will be taken out during the rainstorm. The flow velocity of the pipe water increases and is eventually discharged into the river. 2. The sludge deposited in the drainage pipes will emit a burst of odor in summer when the temperature is hig...

[0002] There are often two problems in underground rainwater pipelines: 1. After the rainwater carries a large amount of solid waste such as leaves, garbage, and mud and sand through the rainwater outlet, it flows directly into the drainage pipe of the drainage diversion pipe or the confluence pipe through the connecting pipe. A large amount of sludge deposits will be produced in the sediment tanks and pipes of the well together with the sundries in the domestic rainwater. Although some of these sludge will be taken out during the maintenance of the drainage pipes, most of them will be taken out during the rainstorm. An increase in the velocity of the water flow in the pipeline, which is eventually discharged into the river

2. The sludge deposited in the drainage pipes will emit a burst of odor in summer when the temperature is high and the air pressure is low, which affects the normal life of residents and pedestrians, and often causes complaints from citizens. In some areas the situation is serious

However, the traditional gullies have the disadvantages of low water intake capacity, clay bricks are mainly used for on-site masonry, the quality is difficult to guarantee, and the loss of water intake grate and manhole cover is serious, which not only brings defects to the urban drainage system, but also Harm to traffic safety
