HANGING APPARATUS IN PROPELLING PIPE

摘要

PROBLEM TO BE SOLVED: To provide a hanging apparatus available for systematically arranging pipes and wires in a propelling pipe on right and left sides during propulsion of the propelling pipe according to a pipe jacking method. SOLUTION: The hanging apparatus in the propelling pipe is formed of an annular plate, a single or a plurality of expanders, and a plurality of mounting stands. The annular plate has a single or a plurality of joint portions, and is arcuately curved along the internal periphery of the propelling pipe. The single or the plurality of expanders are arranged at the joint portions, for circumferentially expanding/contracting the annular plate. The mounting stands are set on the internal surface of the annular plate.
