天津站盾构端头井部位渗漏水治理方案探讨

Exploration on leakage treatment scheme of shield end well of Tianjin station

以天津地铁3号线天津站为例,从管片渗漏、集中涌水、结构渗漏水三方面,分析了地铁在盾构端头井部位发生渗漏的情况,提出了采用注浆技术处理渗漏水的施工方案,并阐述了注浆设计与具体的施工工艺,达到了预期的治理效果。

Taking Tianjin subway line No. 3 Tianjin station as an example, starting from three aspects of segment leakage, central water bursting and structural leakage, the paper analyzes subway shield end well leakage conditions, put forwards construction scheme by grouting technology processing leakage, and describes its design and construction technology, and achieves expected processing effect.
