Huangshi Road Reconstruction and Expansion Project, Bellows Used in Municipal Sewage Pipe Network Laying

In response to the aging of the old sewage pipe network in Huangshi City and the lack of drainage capacity, this road reconstruction and expansion project simultaneously promoted the upgrade of the municipal sewage pipe network, and plastic bellows became the core material selection. Compared with traditional pipes, plastic bellows have excellent ring stiffness, which can adapt to the external forces such as ground subsidence and vehicle rolling that may occur during the process of road reconstruction and expansion, effectively avoid the deformation and damage of the pipe network, and ensure the long-term smoothness of the sewage channel. At the same time, its corrosion resistance is suitable for the complex water quality environment of municipal sewage discharge, reducing the maintenance cost in the later stage and prolonging the service life of the pipe network. At the construction level, the lightweight characteristics of bellows greatly reduce the difficulty of handling and installation, which meets the needs of the compact construction period of road reconstruction and expansion projects. It can efficiently complete the pipe network laying operation and reduce the impact on the surrounding traffic and residents' lives. In addition, the connection method of the bellows is simple and reliable, which can ensure the overall sealing of the pipe network and prevent sewage leakage from polluting soil and groundwater. This application not only improves the municipal sewage system, but also improves the efficiency of urban rain and sewage diversion. It also provides a solid guarantee for the improvement of urban environmental quality after road reconstruction and expansion, and helps Huangshi urban infrastructure upgrade to a more efficient and durable direction.
