摘　　要：在排水管网改造施工过程,因区域内现状地下管网经过多年的无序自行升级改造,管网系统连通情况极为复杂,或施工区周边的厂房、居民楼等建、构筑物阻碍,困难重重。非开挖顶拉管施工工艺以其能很好地解决传统明挖、顶管、拖拉管等工艺无法施工的难题,仅通过单一工作面就能实现管道的扩孔、拉顶、安装,进一步拓宽了城市排水管网施工工艺的道路。During the construction process of the drainage pipe network renovation,due to the disorderly upgrading and renovation of the existing underground pipe network in the area for many years,the connectivity of the pipe network system is extremely complex.And there are numerous buildings and structures such as factories and residential buildings around the construction area.The nonexcavation pipe-jackingand pulling pipe construction technology can effectively solve the problems that traditional methods such as open excavation,pipejackinge,and drag pipe cannot be used for construction.It can achieve pipe expansion,jacking,and installation through a single working face,further expanding the road for urban drainage pipe network construction technology.
