Municipal drainage system

Abstract

The invention discloses a municipal drainage system, and relates to the technical field of urban drainage and waterlogging preventing engineering. The municipal drainage system solves the technical problem of large silt removal difficulty. The municipal drainage system is characterized in that the municipal drainage system comprises a sewer, a water collecting well and a settling tank; the settling tank is arranged between the lower end of the water collecting well and the lower end of the sewer; the two ends of the settling tank communicate with the bottom of the water collecting well and thesewer correspondingly; a plurality of settling plates are arranged in the settling tank; the municipal drainage system further comprises an intercepting net, a supporting table plate and a gravel filtering net frame; the intercepting net is detachably hung on the inner wall of the water collecting well; the supporting table plate is arranged above the settling tank and is slightly higher than thelowest horizontal height of the sewer; the gravel filtering net frame is detachably arranged on the supporting table plate and is arranged in an inverted circular truncated cone shape; the gravel filtering net frame is coaxial with the water collecting well and is located under the intercepting net, and the supporting table plate is arranged in a grid plate shape; and the municipal drainage system has the advantage that no much burden is brought to silt removal by workers.

Description

technical field [0001] The invention relates to the technical field of urban drainage and waterlogging prevention engineering, more specifically, it relates to a municipal drainage system. Background technique [0002] With the acceleration of urbanization, the municipal drainage system is a very important livelihood project. Summer brings heavy rain to the earth, and a smooth drainage system is needed to drain the road surface; but often due to the silting of the drainage system, the drainage system is not smooth, resulting in a reduction in the drainage capacity of the channel and the formation of road accumulation, which makes the road condition complicated and affects the driving of vehicles ; Due to the limited area of ​​the sewer, the water entering the manhole inside from the manhole cover directly enters the sewer; along with the accumulation of debris in the pipeline, the water passage section of the sewer becomes less and the drainage capacity becomes worse.

Problems solved by technology

[0005] However, in the prior art, the sewer needs to be frequently desilted. During the desilting process, the staff needs to lead some dredging tools into the sewer for use. It will cause greater obstacles to the staff, causing the staff to carry heavy dredging equipment and work clothes to cross or remove each plate, which greatly increases the difficulty of dredging for the staff, so it needs to be improved
