GROUND IMPROVEMENT BODY AND BURIED OBJECT MEASURING DEVICE, GROUND IMPROVEMENT BODY CONSTRUCTION DEVICE AND GROUND IMPROVEMENT BODY CONSTRUCTION METHOD
To improve the measurement accuracy of the shape of a ground improvement body and detect buried objects.SOLUTION: A measuring device 100 comprises: a rotating rod 30 that is inserted into a ground improvement body 50 before hardening; a transmitter 112 that is provided on the rotating rod 30 and simultaneously emits ultrasonic waves of different frequencies from the same sound source in the same direction; a receiver 114 that receives reflected waves H1 and H2 reflected from the boundary of the ground improvement 50 with a ground G and a buried object 55 buried in the ground G by difference frequency sound waves S generated by the interaction of ultrasonic waves of different frequencies transmitted from the transmitter 112 and installed in the rotating rod 30; and a detection device 120 that detects a boundary position K1 of the ground improvement body 50 with the ground G and a buried position K2 of the buried object 55 by the time difference between the transmission of the ultrasonic wave of the transmitter 112 and the reception of the reflected waves H1 and H2 of the receiver 114.SELECTED DRAWING: Figure 1
【課題】地盤改良体の造成形状の測定精度の向上及び埋設物の検出を可能にする。【解決手段】測定装置１００は、硬化前の地盤改良体５０に挿入される回転ロッド３０と、回転ロッド３０に設けられ異なる周波数の超音波を同一音源から同一方向に同時に発信する発信部１１２と、回転ロッド３０に設けられ発信部１１２から発信された異なる周波数の超音波の相互作用によって発生する差周波数の音波Ｓが地盤改良体５０の地盤Ｇとの境界及び地盤Ｇに埋設されている埋設物５５で反射した反射波Ｈ１、Ｈ２を受信する受信部１１４と、発信部１１２の超音波の発信と受信部１１４の反射波Ｈ１、Ｈ２の受信との時間差によって地盤改良体５０の地盤Ｇとの境界位置Ｋ１及び埋設物５５の埋設位置Ｋ２を検出する検出装置１２０と、を備えている。【選択図】図１
