摘要： PROBLEM TO BE SOLVED: To easily and highly accurately estimate a position and a dimension of a cavity even in an accuracy-unexpectant place of a geophysical exploration technique without causing adverse influence on strength and administration to a structure or the ground.
SOLUTION: While excavating a hole in a cavity investigating object position in lining concrete C by a bit 2 of a rock drill 4 while keeping feed pressure and stroke pressure in a prescribed value, the existence and the size of the cavity V are estimated by a change in a hole excavating speed of the bit 2 and a torque load applied to the bit 2 at that time.

SOLUTION: A boom of a rock drill movably supports a guide shell carrying a lock drill. Further, a position detecting cylinder R incorporating a magnetic pick-up 8 is arranged in parallel with a drive cylinder D in an actuating part of a boom so that the cylinder R extends and contracts in association with the extension and contraction of the cylinder D. When the drive cylinder is extended for positioning, the position detecting cylinder R is also extended so that the magnetic pick-up 8 detects a magnetic signal and delivers an electric pulse signal. Accordingly, an actuating value of the actuating part is detected.
