Non-excavation Construction Technology for Laying Underground Pipelines in Narrow Spaces Adjacent to Building
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,pipe-jackinge,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.
