摘要
为解决盾构隧道管片下沉超限质量问题,提出采用液压提升法治理方案。以南宁轨道交通1号线某盾构区间洞口管片沉降治理为例,介绍液压提升法的工艺原理、方案设计、作业过程及质量安全保证措施。
Hydraulic lifting treatment scheme was proposed to solve the overlimit settlement of shield tunnel segment.The segment settlement treatment at shield tunnel entrance of Nanning Rail Transit Line 1 was taken as an example to introduce the processing theory,scheme design,operation step,quality and safety guarantee measures of hydraulic lifting method.
