摘要
结合毛坝1号隧道左线ZK297+640涌水塌方段实例,研究并实施了自进式锚杆结合小导管预注双液浆的施工方案,方案经过实施,取得了良好效果。
Combining with the collapsing and gushing water instance of Maoba No. 1 tunnel ZK297 ＋ 640 left line, this thesis studies and implements the program of combining the serf-feeding anchor rod with ductule double-liquid grouting and achieves good results.
