摘要
以复杂环境下联络通道地层帷幕止水施工控制为例,介绍了试验段施作、注浆控制、注浆效果检查等关键环节,通过试验段获取关键参数后进行工程施工,论证了采用C-GL超注浆液配合GL超注浆剂的TGRM前进式深孔注浆可有效隔绝富水砂卵石地层中地下水,保障了后续暗挖施工安全,为类似工程提供一定参考。
The construction control of stratum curtain water stop in the contact channel under complex environment is taken as an example,and the key links such as application in the test section,grouting control and grouting effect inspection are introduced.After obtaining key parameters in the test section,engineering construction is carried out,and it is demonstrated that TGRM advanced deep hole grouting using C-GL super-grouting liquid and GL super-grouting agent can effectively isolate groundwater in the water-rich sand and gravel formation.It guarantees the safety of subsequent excavation construction and provides a certain reference for similar projects.
