Urban inland river renovation project, steel belt bellows drainage application case

Urban inland river is an important part of urban ecosystem, and its remediation project is directly related to the improvement of urban flood control and drainage capacity and water environment quality. In a city inland river remediation project, in view of the aging of the original drainage pipe network, insufficient drainage capacity, easy to cause flood season waterlogging and sewage direct discharge, steel bellows were applied to drainage system construction, and good practical results were achieved.

The geological conditions along the inland river of the project are complex, with large fluctuations in soft soil foundation and terrain, which requires high settlement resistance, ring stiffness and corrosion resistance of drainage pipelines. The steel belt corrugated pipe relies on its unique structural advantages. The outer polyethylene material is corrosion-resistant, the inner wall is smooth and not easy to accumulate pollution, and the middle steel belt layer greatly enhances the ring stiffness, which can effectively resist soil pressure and ground loads, and is suitable for complex geological environments.

During the construction process, the steel belt corrugated pipe adopts a flexible connection method, which is convenient and efficient to install, shortens the construction period, and reduces the impact on the surrounding environment. After being put into use, the water-passing capacity of the drainage system is significantly improved, and the water accumulation along the coast can be quickly diverted during the flood season to avoid waterlogging. At the same time, the good sealing performance effectively prevents sewage leakage, reduces pollution to the water body in the river, and helps to gradually improve the water quality of the river.

This application case shows that the steel belt bellows have high adaptability and practicability in the drainage system of urban inland river regulation, which can provide reference for the selection and construction of drainage pipes of similar projects, and promote the continuous optimization of the ecological environment of urban inland rivers.
