摘要
随着非开挖铺管技术的不断应用，遇到的困难越来越多，针对施工中存在的诸如硬土层中导向孔的形成、硬土层扩孔钻头的改进、软土层扩孔钻头及设备、恶劣工作面的多束钢管反拉等问题提出了相应的解决方法。
The technology of no dig installation is applied more extensively in recent years The difficulties encountered are more and more,such as drilling pilot hole in hard soil formation,improving the reaming bit in the formation,choosing reaming bit and equipment in soft soil formation,and pulling back bunched pipes from problem section Some solutions for the difficulties in construction are presented
