CONCRETE JACKED PIPE FOR PIPE JACKING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete jacked pipe capable of being more inexpensively and easily manufactured than a steel-concrete composite jacked pipe, with shear-resistant strength equivalent to an intermediate level between the shear-resistant strength of the steel-concrete composite jacked pipe and the shear-resistant strength of the concrete jacked pipe.SOLUTION: On the outer periphery of a concrete jacked pipe 1 body of a concrete jacked pipe forming a pipeline by pushing out the pipes into the ground while sequentially connecting the pipes to a rear end side by a jacking machine, a plurality of circular ring-shaped wrap-around materials 6 made of a strip-shaped material such as band steel are provided at intervals in an axial direction of the jacked pipe 1 body.
