Title:
地中物の形状評価方法及び地中物計測装置
Document Type and Number:
Japanese Patent JP7039958
Kind Code:
B2
Abstract:
To provide a shape evaluation method and an underground object measurement device capable of further accurately evaluating a shape of an underground object.SOLUTION: A measurement unit 20 of an underground object measurement device 10 for sending-receiving an electromagnetic wave, is inserted into a measurement hole H1 extended in the depth direction in a position separated from a pile P1. This measurement unit 20 is descended up to the measurement depth in the measurement hole H1, and while rotating in its measurement depth, the electromagnetic wave having a polarized plane inclined to verticality is dispatched, and the electromagnetic wave reflected by the pile P1 is received. A shape evaluation device 16 of the underground object measurement device 10 executes formation processing of a shape of the pile P1 by calculating a distance with the pile P1 from the measurement unit 20 by using a detection time (a measured value) up to receiving the electromagnetic wave reflected by the pile P1 after dispatching the electromagnetic wave.SELECTED DRAWING: Figure 1
