摘　　要：介绍了上海世博北京西路～华夏西路电力电缆隧道工程的5^#工作井地下连续墙施工中，针对施工周边环境复杂、重大风险源较多和地下深层障碍物位置不明确的情况，选用了气动钻机进行探孔灌浆，以及钢套管钻进法的全回转钻机进行深层障碍物清除，既保证了障碍物区域地下连续墙的顺利完成，又保护了临近密集的地下管线和加油站，同时保证了盾构顺利进洞。In the construction of 5^# work well underground continuous wall of Power Cable Tunnel from West Beijing Road to West Huaxia Road of Shanghai Expo , pneumatic drill is used for drilling and grouting, and full rotary with steel casing drilling method is used for deep obstacle cleaning, because of the complicated environmental , high risk and the unclear deep underground obstacle location. The method adopted guarantee the successful completion of underground wall near the obstacle area and protect the intensive underground pipe wire and gas station, at the same time, ensure the shield go into the hool smoothly.
