GROUND SURVEY DEVICE
To provide a ground survey device which easily grasps characteristics of a ground in a short time.SOLUTION: A ground survey device 9 surveys a ground 4 by measuring shear waves propagating inside the ground 4. A thrusting part 10 is thrusted into a cutting face 4a from inside an element 6 boring the ground 4. A plurality of receiving piezoelectric parts Rto Rfor receiving shear waves propagating inside the ground 4 are arranged at an interval D in the thrusting part 10. The thrusting part 10 is thrusted into the cutting face 4a from a tip of a steel pipe boring inside the ground 4. The thrusting part 10 is thrusted into the cutting face 4a from a tip end part of the steel element 6 of an under-track crossing construction method for constructing an underground structure under a track without excavating. The thrusting part 10 is a tabular member whose planar shape is a reverse V-shape, and the receiving piezoelectric parts Rto Rare mounted at the interval D along a lengthwise direction of the thrusting part 10.SELECTED DRAWING: Figure 2
【課題】短時間で簡単に地盤の特性を把握することができる地盤探査装置を提供する。【解決手段】地盤探査装置９は、地盤４内を伝搬するせん断波を測定してこの地盤４を探査する。刺さり込み部１０と、地盤４を掘進するエレメント６内から切羽４ａに刺し込まれる。受信圧電部Ｒ1〜Ｒ14は、地盤４内を伝搬するせん断波を受信し、刺さり込み部１０に間隔Ｄをあけて複数配置されている。刺さり込み部１０は、地盤４内を掘進する鋼管の先端部から切羽４ａに刺し込まれる。刺さり込み部１０は、非開削で線路下に地下構造物を構築する線路下横断工法の鋼製のエレメント６の先端部から切羽４ａに刺し込まれる。刺さり込み部１０は、平面形状が逆Ｖ字状の板状部材であり、受信圧電部Ｒ1〜Ｒ14は刺さり込み部１０の長さ方向に沿って間隔Ｄをあけて装着されている。【選択図】図２
