Analysis and Engineering Exploration of Sewage into Utility Tunnel
At present,the construction of utility tunnel has become a large scale in China.In the utility tunnel,the single-cabin branch utility tunnel of the water supply pipe,reclaimed water pipe,electric power pipe and communication pipe is mainly,and a few is constructed for the sewage cabin,rainwater cabin and gas cabin.Due to the high requirements of gravity rainwater and sewage pipes on the elevation,branch pipe connection,operation and maintenance,there are few cases of rainwater and sewage merging into utility tunnel in construction projects.Taking the utility tunnel in Yuhong Road in Chengdu as an example,by analyzing the overall situation and sewage into-tunnel scheme of the project,the cross section of utility tunnel,the pipelines into utility tunnel,the horizontal and vertical of the utility tunnel,and the design of typical joints are introduced.According to the sewage into-tunnel scheme,the targeted measures such as sewage pipe material,connecting well and automatic flushing systems are introduced,and the basic conditions of sewage into tunnel are summarized in order to provide the reference for similar utility tunnel projects.
