暗挖车站跨既有隧道施工技术

Mining Station Tunnel Construction Technology across Existing Tunnel

针对洞桩法暗挖车站跨既有隧道施工项目,通过增加施工通道,采用门式钢架加固等创新、改良工艺,解决了施工工序转换的难题,节约工程成本,降低施工风险。

Hole pile mining station across the existing tunnel is still the country＇s first such construction project.By increasing construction access,the use of innovative portal steel frame reinforcement,improved technology,the problem of converting the construction process are solved,the project cost saved,construction risk reduced.
