Abstract:Pipe jacking construction, as a core technology of trenchless underground pipeline construction, enables pipe segments to be jacked in one by one underground through a pipe jacking machine and jacking device within open caisson, which has the advantages such as not necessary to excavate the surface and little disturbance to the surrounding environment. Relying on a practical case of trenchless pipe jacking in a municipal sewage pipeline project, by systematically sorting out the technical challenges and core issues encountered in pipe jacking construction management, the relevant control measures and innovative technical schemes are proposed in order to provide the practical references for the management of similar trenchless pipe jacking projects, and to support the high-quality advancement of urban infrastructure construction and the sustainable development of the ecological environment.
