南宁市轨道交通4号线长盾构区间结构防水设计

Structural Waterproofing Design for Long Shield Tunnel of Nanning Subway Line 4

以南宁轨道交通4号线五象岭站-玉象路站区间盾构法隧道工程为例,介绍了盾构结构防水设计,包括管片结构自防水、管片接缝防水、隧道接口防水等,重点阐述了多孔三元乙丙橡胶密封垫在本项目中的设计应用。

Taking the shield tunnel work between Wuxiangling Station and Yuxianglu Station of Nanning Subway Line 4 as an example, the article introduces the waterproofing design of shield structures, including segment structure self-waterproofing,segment joint waterproofing, tunnel interface waterproofing etc. It focuses on the design application of multi-hole EPDM rubber gasket in this project.
