Cable trenches,utility tunnels,buried pipelines and overhead lines together constitute the urban municipal pipe network construction system.Compared with utility tunnel,cable trench has the characteristics of small cross-sectional size and low investment.However,there is currently no national standard for cable trench construction in China,and the construction of cable trench in various regions is still under exploration.It relies on the cable pipe gallery project in a certain area of Nanning,Guangxi Zhuang Autonomous Region,summarizes the experience of cable pipe trench section design,horizontal&vertical designand node design,and puts forward several thoughts on promoting the development and construction of this field.
