Research method : Ordinary concrete-water glass two-shot grouting and extra fine concrete-water glass two-shor grouting are adopted in construction of the pilot tunnel under karst cave 2 . By this way it is difficult to pass through one cave .

研究方法：在2溶洞下导坑施工中，采用普通水泥-水玻璃 双 液浆和超细水泥-水玻璃双液浆注浆，十分艰难地通过了溶洞。

Application of Two-Shot Solution Grouting to Large Slurry Balance Shield Tunnelling

双 液注浆在大型泥水平衡盾构施工中的应用

The technique of two-shot grouting would be improved such as changing grouting from primary grouting into secondary grouting increasing grouting pressure of secondary grouting and improving uniformity of reinforced soil mass .

施工过程中， 双 液 注浆工艺有待改善，应改一次注浆为二次注浆，同时提高二次注浆的注浆压力，提高加固土体的均匀性。

Two-shot binding : Adhesive binding in which the first application is of PVA adhesive the second of hot-melt adhesive .
