地下工程衬砌渗漏水治理综合分析方法研究

Research on comprehensive analysis method for leakage treatment of underground engineering lining

隧道等地下工程在建设期及运营期由于施工质量等问题导致衬砌渗漏水现象屡见不鲜。针对建设期隧道衬砌渗漏水的治理,提出一套综合分析方法。首先通过物探方法查找到水源,同时开孔泄压;其次进行合理布孔设计并进行系统注浆;然后开展重点区域针对治理,针对剩余渗漏水区域,对出水点区域进行钻孔注浆;重点针对治理后,进行补充加固治理,对衬砌面渗水区域进行注浆。实践证明,该综合治理方法对衬砌渗漏水的根本治理具有较佳的效果,可为类似工程提供借鉴。

It is not uncommon for underground works such as tunnels to cause leakage of lining due to problems such as construction quality during construction and operation. A comprehensive analysis method is proposed for the treatment of seepage leakage of tunnel lining during construction period. Firstly,the water source is found through the geophysical method,and the hole is released at the same time;secondly,the reasonable hole design is carried out and the system grouting is carried out;then the key areas are carried out for the treatment,and the remaining water leakage area is drilled and grouted for the water discharge point area. After focusing on the treatment,the supplementary reinforcement treatment shall be carried out to grout the seepage area of the lining surface. Practice has proved that the comprehensive treatment method has a better effect on the fundamental treatment of lining leakage water,and can provide reference for similar projects.
