IPC: E21D9/093
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To calculate the traveled distance of a head pipe, while reducing errors, and accurately propel the pipe along the planned track, and facilitate maintenance. SOLUTION: This propulsion method involves controlling, using a controller, an adjustment jack whose head pipe is adjustable in direction, while measuring the traveled distance of the head pipe by use of a distance measuring device 31, and propelling the head pipe so that the head pipe goes along the planned track including a curved part.
