Title:
QUALITY CONTROL METHOD OF SOIL IMPERMEABLE LAYER
Document Type and Number:
Japanese Patent JP2023156205
Kind Code:
A
Abstract:
To provide a quality control method of a soil impermeable layer capable of controlling quality of a soil impermeable layer more efficiently and with higher precision than conventional methods.SOLUTION: A quality control method of a soil impermeable layer includes at least: an RI scanning estimation step of estimating a degree of compaction and/or a permeability coefficient of the soil impermeable layer by moving RI scanning means 100 to measure in a construction range of the soil impermeable layer; an RI scanning determination step of determining whether or not the degree of compaction and/or the permeability coefficient obtained by the RI scanning estimation step satisfies an RI scanning quality standard; a test hole type estimation step of estimating the degree of compaction by a sand substitution method or a sand pushing method when it is determined that the RI scanning quality standard is not satisfied in the RI scanning determination step; and a test hole type determination step of determining whether or not the degree of compaction obtained by the test hole type estimation step satisfies a test hole type quality standard.SELECTED DRAWING: Figure 4
