Yichang River Water Conservancy Renovation, Plastic Pipeline Supporting River Peripheral Pipeline Network Project

Water conservancy regulation along the Yangtze River in Yichang is an important measure to ensure the safety of the Yangtze River coastline and improve the city's flood control and drainage capacity. In the pipeline network project around the river, plastic pipes have become the preferred pipe material for supporting construction due to their comprehensive properties such as light weight, high strength and excellent hydraulic characteristics. The inner wall of this type of pipe is smooth and the resistance when transporting fluid is small, which can effectively improve drainage efficiency and reduce river flood pressure.

The geological conditions along the river are complex, and the soil water content in some sections is high and corrosive to a certain extent. Plastic pipes have excellent acid and alkali corrosion resistance, and can be buried in the ground for a long time without additional anti-corrosion treatment, which greatly reduces the later maintenance cost. Its good flexibility and anti-uneven settlement ability can adapt to the slight changes in the topography of the river bank, ensure that the pipe network interface is tight and non-leaking, and avoid sewage overflow and pollution of the river water, which is of great significance for protecting the water ecology of the Yangtze River.

In the specific construction, the plastic pipeline is light in weight, which is convenient for handling, downpipe and quick connection in the narrow riparian belt, shortening the operation period and reducing the disturbance to the embankment and surrounding environment. The pipe material can be customized in diameter and ring stiffness according to the engineering needs to meet the requirements of different burial depths and loads, and can be flexibly connected with inspection wells, interception wells and other structures to build a complete sewage interception and rainwater drainage system along the river.

At present, Yichang's water conservancy remediation along the river focuses on the integration of engineering measures and ecological restoration. Durable and reliable plastic pipes are selected for supporting pipe network projects, which strengthens the resilience of infrastructure from the source. Through scientific design and standardized laying, these buried "veins" will continue to provide solid support for smooth river flow, bank slope stability and water environment improvement, and help paint the riverside picture of clean water and green banks.
