摘要
针对南疆铁路吐库二线中天山特长隧道高压涌水情况,对高压富水段超前注浆堵水进行了试验研究,对超前注浆堵水试验类型进行了划分,并设计了试验过程,通过对试验结果的处理分析,确定出适用于中天山特长隧道高压富水段的超前注浆堵水方式、注浆材料以及配套注浆设备等关键技术问题。
According to the high-pressure blow at Zhongtianshan Super-large Tunnel along Turpan-Korla Secondary Line of South Xinjiang, the paper undertakes the test and research on the advanced grouting and plugging water at high-pressure rich water section, classifies the types of the advanced grouting and plugging water, designs the test process, and identifies the key technical issues, including the advanced grouting and plug- ging water, the grouting materials and the grouting equipment, suitable for the high-pressure rich water section of Zhongtianshan Super-large Tun- nel by bavin~ the treatment analysis of the test results.
