Document Type and Number:
Japanese Patent JP2015072225
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bedrock mounting structure suitable for long-period monitoring and easily adaptive to even a change of a measurement position.SOLUTION: In a bedrock mounting structure of a displacement sensor, a front side anchor 5, a sensor mounting member 8 mounted with the displacement sensor 7 and a rear side anchor 6 are connected to each other and are disposed inside an observation hole of bedrock. The sensor mounting member 8 comprises: a first connection part 46 in which a guide rod 45 is erected; and a second connection part 48 formed with a guide hole 47 through which the guide rod is inserted. In the sensor mounting member 48, a sensor body 41 of the displacement sensor 7 is inserted through a body insertion hole 49 formed in the first connection part 46, and the sensor body is fixed to the opening peripheral edge of the body insertion hole. By such a configuration, a rod-like member 42 of the displacement sensor 7 can follow movement of the front side anchor 5, and the sensor body 41 can follow movement of the rear side anchor 6.
