摘要
以野三关隧道富水溶腔溃口坍塌段处理为例,介绍在排水降压条件下采用注浆加固方式进行坍方处理施工过程,钻孔注浆机械设备配套以及有边界条件下注浆过程控制措施,以期对类似工程问题的处理提供一定的借鉴作用。
Taking collapse treatment of cavity rich - water of the Yesanguan Tunnel for example, the construction processes to treat collapse with the method of grouting solid in the condition of drainage and pressure decreasing were introduced. The machinery and equipment of process in the boundary conditions were also discussed, with similar projects. drilling grouting as well as control measures of grouting a view to provide a reference for dealing with issues of similar projects.
