MULTIPLE-TYPE PIPE JACKING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multiple-type pipe jacking method burying by arranging a plurality of pipe lines in parallel from one shaft. SOLUTION: The multiple-type pipe jacking method comprises a boring process forming an accurate tunnel pit along a planned route by a main advancing machine having a cutter face plate on the front end of a cylindrical front shell and equipped with a plurality of directional control jacks in a connecting section between the cylindrical front shell and a rear shell and the other process forming the tunnel pit while being delayed by a certain distance from the main advancing machine by making the main advancing machine as a guide by connecting an auxiliary advancing machine having the cutter face plate on the front end to the side of the main advancing machine.
