Municipal engineering drainage pipeline and construction process thereof

Abstract

The invention relates to a municipal engineering drainage pipeline, and belongs to the field of municipal engineering. The municipal engineering drainage pipeline comprises a drainage main pipe and a plurality of drainage branch pipes, wherein the plurality of drainage branch pipes are distributed on the drainage main pipe at intervals in the length direction of the drainage main pipe and communicate with the drainage main pipe; a filter screen plate is arranged on each drainage branch pipe; the filter screen plates are rotationally arranged in the drainage branch pipes; telescopic strips are arranged on the sides, away from the rotating ends, of the filter screen plates; a plurality of groups of driving assemblies used for driving the filter screen plates to rotate are arranged on the drainage main pipe; each group of driving assemblies can drive the filter screen plates in at least two drainage branch pipes to rotate synchronously; a sewage collecting cavity is formed in one side of each drainage branch pipe; and a sewage collecting through hole communicating with the sewage collecting cavity and a blocking plate used for blocking the sewage collecting through hole are arranged on each drainage branch pipe. The municipal engineering drainage pipeline has the effects that impurities can be conveniently cleaned in the drainage branch pipes so as to reduce the impurities entering the drainage main pipe, and therefore the cleaning difficulty of the impurities in the drainage main pipe is reduced.

Description

technical field [0001] The application relates to the field of municipal engineering, in particular to a municipal engineering drainage pipe and its construction technology. Background technique [0002] Municipal engineering refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns, and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects. Drainage pipeline refers to the pipeline system composed of pipes and channels for collecting and discharging sewage, waste water and rainwater and its ancillary facilities, in which pipelines are the main body.

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned technical solution cleans up the impurities in the drainage main pipe, because a large amount of impurities enter the drainage main pipe from the drainage branch pipe, resulting in more impurities accumulated in the drainage main pipe, making cleaning difficult Big
