Abstract:
[PROBLEMS] A penetration-type pipe strain gauge easily transportable and easily installable in various places at low cost in a short period of time to measure strain produced in a shallow layer of the ground. [MEANS FOR SOLVING THE PROBLEMS] Strain gauges (27) are attached to the outer peripheral surface of an inner pipe (12), and a pipe strain gauge body (11) is formed by integrally incorporating the inner pipe (12) in an outer pipe (13). A boring screw (18) is provided at the forward end of the pipe strain gauge body (11). A rotary tool mounting part (13b) for mounting a tool for rotating the pipe strain gauge body (11) is formed at the rear end of the strain gauge body (11). The pipe strain gauge body (11) is buried in the shallow layer of the ground by using the rotary tool.
