摘要
在某市供水网络干线工程1# 隧洞西坑段开挖施工中,采用深孔预注浆技术,成功地通过了西坑F38断层破碎带、溶槽、溶洞等特殊地质段,止住了大涌水和大塌方,遏止了地下水位下降,保证了地表建筑物安全和隧洞按期通水。
Deep hole pre-grouting technique is applied to desist from water and reinforce country rocks in advance of tunneling. Using this technique in practical tunneling in a city,the stability of the country rocks was improved,and the tunnel had successfully passed bad geological region with fault,karst,water burst and large collapse. As a result,the safety of buildings on the ground and due data for water supply can be assured.
