- Abstract:
- The South-to-North Water Diversion Project with supply capacity of 10×104 m3/d in Wenzhou, is an emergency water supply pipeline project that effectively alleviates the supply-demand contradiction of water resources in Yueqing and ensures the safety of drinking water for the general public. The total pipeline pile length is approximately 8.6 km and the overall design pipeline length is around 11.2 km. Among them, DN1 400 water supply pipes are utilized in Longwan section, a 2×DN1 000 dual- pipe arrangement is employed in Oujiang River’s north and south branches, while DN1 200 water supply pipes are used in Qidu section. The project adopts the horizontal directional drilling method for water supply pipeline to cross the river. Its design and construction points are elaborated, the impact of the project is evaluated, and the corresponding quality control measures are provided. The successful execution of this project could provide reference for the construction of long-distance, large-diameter water supply pipelines.
