Title:
METHOD FOR BURYING MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JP2016079705
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measuring instrument used for monitoring during ground improvement work and surveys after completion, the measuring instrument being economically efficient and free of a concern over wire breaking.SOLUTION: An established area 2, to which a cement-based solidification material is added and mixed, is formed in a ground 1, while a measuring sensor 5 is installed inside a hollow tube 3, after detachably fitting a closing part 7 on an opening 6 at a tip of the hollow tube 3 and fitting an end of a holding wire 8 near a central part on an inner surface of the closing part, the measuring sensor being fitted on the holding wire. The hollow tube 3 is penetrated into the established area 2, to a prescribed depth, before the cement-based solidification material solidifies. Then, the other end of the holding wire 8 is supported at a ground surface side such that the holding wire is almost parallel with a material axis of the hollow tube 3, and only the hollow tube 3 is pulled out from the established area 2. This way, the measuring sensor 5 is left in the established area 2, along with the holding wire 8 and the closing part 7.SELECTED DRAWING: Figure 2
