Tunnel face forward exploration system and method

摘要

PROBLEM TO BE SOLVED: To provide a tunnel face forward exploration system and a method capable of efficiently exploring regardless of the underground environment with less work. SOLUTION: The direct wave D of the vibration at the time of hitting or the vibration at the time of rupture during the tunnel construction on the face surface K is installed at at least two different places of the tunnel pit wall W rearward by a predetermined distance from the face surface K. The vibration receiving sensor 18 that detects the reflected wave R reflected in the ground G in front of the face, the recording unit 20 that records the detected vibration data, and the vibration data transmitted wirelessly from the recording unit 20 are wirelessly received. The wireless communication unit 14 and the exploration unit 14 for exploring the condition of the ground G in front of the face based on the received vibration data are provided. In this way, it can be installed regardless of the shape of the lock bolt nut, and the trigger signal can be sent at any timing. [Selection diagram] Fig. 1
