摘要
隧道衬砌渗漏水是隧道常见病害,危及隧道结构安全和运营安全。文章针对目前常规处治方式存在的不足提出了一种新的衬砌渗漏水治理技术:在渗漏缝周边进行三边或周边开槽,并安装多功能排水槽,必要时在两侧边槽布设可调式螺栓和钢条对其接缝处施加压力,结合细排水管将多个多功能排水槽连接并将渗漏水引排到离隧道最近排水管中,以此解决隧道衬砌渗漏水问题。其主要优点是可集水引排,把原来被动排水变为主动排水,同时又具有维护、更换、清理和疏通等功能。经工程实践检验证明,采取这种新的渗漏水处理技术,可以取得良好的治理效果。
Water leakage of tunnel lining is a common disease which endangers the safety of tunnel structure and operation.In light of the shortcomings of current treatment methods,a new treatment technology was proposed,namely grooves are made at three sides or around the place of leakage and multi-function drainage channels are installed,adjustable bolts and steel strips are arranged at the two side grooves to apply pressure at the connection when it′s necessary,several multi-function drainage channels are connected by thin drain pipes to drain the water to the nearest drain pipes.The main advantages are that water can be collected and drained and it turns the passive drainage into active drainage,it also has the functions of maintenance,replacement,cleaning and dredging.The engineering practice shows good effect is achieved by this new treatment technology.
