Concrete pipes of pipe-jacking, as a concrete pipe with special stress in jacking construction, its internal force distribution is different from that of the others, which results in some difference for pipe-jacking in design, fabricating technology, etc from ordinary pipes. Fabricating qualify for each concrete pipe determines the success or failure of pipe-jacking engineering. In consideration of particularity and importance of design and fabricating technology of pipe-jacking, combined with fabricating cases of concrete pipes applied to curve pipe-jacking tunnel, this paper introduces in detail field fabricating technology such as mould structure, fabrication and installation of waterstop steel ring, and construction technology process, which provides relevant information for design and fabricating technology improvement of concrete pipes, and, meanwhile, also supplies reference for similar projects.
