Construction method of sewage distribution main pipe network

Abstract

The invention discloses a construction method of a sewage distribution main pipe network, and belongs to the technical field of pipeline construction. A newly-built sewage lifting pump station and a newly-built sewage pressure conveying pipeline are included. The sewage pressure conveying pipeline comprises a land sewage pipeline, a river crossing pipeline, a road crossing pipeline, a submarine pipeline and a pump station outdoor rain sewage drainage pipeline. The land sewage pipeline adopts PE pipeline construction, the river crossing pipeline or the road crossing pipeline adopts PE tractionpipeline construction, and the submarine pipeline adopts offshore slotting buried pipe construction. In PE pipeline construction, materials are environmentally friendly, corrosion resistance is good,strength is high, and construction stability is guaranteed. In PE traction pipeline construction, pipelines are deeply buried, construction is safe, horizontal directional accurate drilling construction is adopted, and the pipeline construction efficiency is improved. In offshore slotting buried pipe construction, the elevation of the foundation base slot bottom is accurately controlled, and the foundation slot construction quality is guaranteed. Pipe land assembly welding and offshore butt joint are adopted, the construction period is shortened, the construction cost is reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a construction method for a sewage distribution main network. Background technique [0002] The existing sewage pipeline construction, due to the complicated construction path of the pipeline, needs to face different construction environments such as roads, rivers, and seas. During the construction process, it will have an impact on the surrounding environment and traffic, and it is easy to damage the road surface, River course; affecting the passage of vehicles and sea vessels; causing danger to all kinds of buried integrated pipelines, poor construction safety and environmental protection, and low construction efficiency. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide a construction method for the sewage distribution main network that can protect ...
