Document Type and Number:
WIPO Patent Application WO/2007/083589
Kind Code:
A1
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.
