POSTURE DETECTION METHOD FOR UNDERGROUND PRORELLING BORING MACHINE AND DEVICE THEREOF

摘要

PURPOSE:To transmit information about the posture of an underground advancing boring machine which is loaded on a drain water feed pipe inside the underground advancing boring machine by means of wireless, and to receive the information on the side of a shaft. CONSTITUTION:A method which detects the posture of an underground advancing boring machine alpha comprises detecting posture information theta and phi about the tip A of the machine at first and converting the detected posture information thetaand phi into a supersonic wave signal by means of pulse coded and then transmitting the data as a supersonic pulse signal S3 by means of a medium flowing in a water feed axial pipe 5 and a drain water outer pipe 6 installed inside the underground advancing boring machine alpha. The supersonic pulse signal S3 is received and reproduced inside the feed water axial pipe 5 and the drain water outer pipe 6 or their extension lines, thereby detecting the tip posture information theta and phi of the underground advancing boring machine alpha based on the application of the supersonic waves by means of wireless on the side of a shaft H which is advancing.
