轨道交通区间隧道二衬结构渗漏水施工治理技术

Construction control technology for water leakage of lining structure of rail transit section tunnel

轨道交通隧道施工中因排水系统衔接不畅、初期支护和二次衬砌质量不合格、水文地质条件等原因造成二次衬砌渗漏水。根据渗漏程度、渗漏面及渗水源有不同的分类。文章以锦江路站-黄河北路站区间隧道作为研究实例,该项目施工过程中,在因地制宜、堵排结合、综合治理原则下,施工单位采取了多种不同施工方法进行治水。

Rail transit tunnel construction due to the drainage system connection is not smooth,the initial support and secondary lining quality is not qualified,hydrogeological conditions and other reasons caused by the secondary lining leakage.According to the seepage degree,seepage surface and seepage water source have different classification.This paper takes the tunnel between Jinjiang Road Station and Huanghe North Road Station as an example.In the construction process of this project,under the principle of adjusting to local conditions,combining plugging and drainage,and comprehensive treatment,the construction unit adopts a variety of different construction methods for water control.
