Rain and sewage renovation in old residential areas of Xiangyang, corrugated pipe laying outdoor sewage pipeline project

Many old residential areas in Xiangyang that were built earlier were restricted by the original construction conditions, and the phenomenon of mixed connection of rain and sewage pipelines was common, which not only affected the sewage discharge efficiency, but also easily caused problems such as water accumulation and odor diffusion in rainy days, which caused troubles to residents' lives. The transformation of rain and sewage diversion has become a key measure to solve such problems. Among them, corrugated pipes have become the preferred material for outdoor sewage pipeline laying due to their excellent performance.

In the rain and pollution renovation project of Xiangyang's old residential area, the application suitability of bellows is prominent. The outdoor terrain of the old residential area is complex, and the pipeline laying path often needs to bypass the original buildings and greening facilities. The bellows have good flexibility, can flexibly adjust the direction, and are suitable for narrow space operations. At the same time, its corrosion resistance and wear resistance characteristics can cope with the complex underground soil environment and effectively prolong the service life of the pipeline.

During the construction process, the construction team strictly followed the standard process: first, combined with the original pipeline layout of the community, accurately locate the direction of the sewage pipeline, scientifically excavate the trench to ensure that the depth and slope meet the sewage discharge requirements; then lay the bellows, pay attention to the sealing treatment of the interface, and avoid the hidden danger of leakage; the backfill stage adopts a layered compaction process to ensure the stability of the pipeline.

Through the installation of outdoor sewage pipelines through corrugated pipes, Xiangyang's old community realizes rain and sewage diversion, and sewage can be smoothly connected to the municipal sewage system. Rainwater can be quickly discharged into the pipe network, effectively reducing the risk of waterlogging in rainy days, reducing the impact of sewage on the community environment, and effectively improving the living comfort of residents. It also provides a practical reference for the treatment of rain and sewage in similar old communities.
