Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road engineering, and particularly relates to a road underground sewage pipe design structure. BACKGROUND

[0002] In modern urban infrastructure construction, the road underground sewage pipe system plays a crucial role in collecting and transporting urban domestic sewage to treatment facilities.

[0003] However, the interior of the existing road underground sewage pipe is prone to accumulate sundries and garbage, which requires cleaning personnel to enter the pipe interior for cleaning. The sundries and garbage may be derived from improper discharge of household garbage, silt brought in by rainwater, fallen leaves and other natural substances, and sheddings caused by pipe aging. The accumulated substances not only reduce the flow efficiency of the pipe and increase the risk of blockage, but also may cause sewage overflow, which seriously affects the urban environment and the quality of life of residents.

[0021] Preferably, the mesh size of the blocking cover is larger than the mesh size of the filter cylinder.

[0022] By adopting the technical scheme, the sewage is subjected to hierarchical filtering, the fine mesh of the filter cylinder is responsible for intercepting small sundries and particles, and the larger mesh of the blocking cover is responsible for intercepting larger sundries, thereby ensuring the efficiency and pertinence of the filtering process.

[0023] Preferably, the blocking part is a round cast iron manhole cover, and the bottom of the blocking part is provided with a pipe clamp.

[0024] By adopting the technical scheme, the round cast iron manhole cover can prevent pedestrians from falling and show the position of the sewer pipe.
