Non-excavation laying method for pipeline and tunnel using temporary composite pipe

摘要

PURPOSE: A temporary installation multiunit tube and a duct/tunnel non-excavation burying method using the same are provided to facilitate construction and reduce construction costs by reducing raw material costs. CONSTITUTION: A temporary installation multiunit tube comprises a split corrugated pipe or rugged pipes(7,7'), a horizontal joint, and an injection hole(15), and outside filler-cum-stiffener(17). The split corrugated pipe has the unit length(L) in the vertical direction of a duct and a tunnel. The split corrugated pipe has a longitudinal joint(11) on both ends thereof, respectively. The injection hole is installed in the split corrugated pipe or the rugged pipe. The outside filler-cum-stiffener is installed on the outside of the split corrugated pipe or the rugged pipe.
