河道内合流制截污干管的设计

Design of sewerage intercepting trunk in combined system along river channel

沿河道内敷设合流制截污干管,因河道地质条件复杂,需考虑管道抗浮稳定性、不良地基处理的问题。结合浠水县沿浠水河河道内截污干管的设计,总结了在管材选择、不良地基处理方面的设计经验,提出了在河道内设计截污干管的设计理念。

Due to complicated geological conditions of river channel, such problems as anti-floating stability of pipelines and bad foundation treatment etc. need to be considered in laying of sewerage intercepting trunk in combined system along river channel. In combination with the design of sewerage intercepting trunk in combined system along the Xishui river channel in Xishui county, the design experience in selection of pipe material and treatment of bad foundation was summarized, and the design concept for intercepting trunk along river channel was put forward.
