UNDERGROUND OBSTACLE DETECTION METHOD, AND METHOD FOR INSTALLING STEEL PIPE INTO UNDERGROUND
To provide an underground obstacle detection method for detecting a position of an underground obstacle when a steel pipe is pressed into the underground in a vertical direction while rotating the steel pipe around a central axis, and a method for installing the steep pipe into the underground.SOLUTION: A projection 11 is provided in a part in a circumferential direction of a lower end of a steel pipe 6. A change in vibration during rotation of the steel pipe is monitored using a vibration measuring device 12 installed on the ground side of the steel pipe. The change in the vibration due to contact of the projection of the steel pipe with an underground obstacle (H-steel residual material 3z) is detected from the change of the vibration during rotation of the steel pipe, and a position of the underground obstacle is specified from a rotation angle position of the projection. A mark 13 is attached to a position corresponding to the position in the circumferential direction of the projection on the ground side of the steel pipe.SELECTED DRAWING: Figure 2
【課題】鋼管をその中心軸回りに回転させながら地中に鉛直方向に圧入する際に、地中支障物の位置を検知する地中支障物検知方法、並びに地中への交換の設置方法を提供する。【解決手段】鋼管６の下端の円周方向の一部に突起部１１を設ける。鋼管の地上側に設置された振動測定器１２を用いて、鋼管の回転中の振動の変化を監視する。そして、鋼管の回転中の振動の変化から、鋼管の突起部と地中支障物（Ｈ鋼残材３ｚ）との接触による振動の変化を検出し、そのときの突起部の回転角度位置から、地中支障物の位置を特定する。また、鋼管の地上側で、突起部の円周方向の位置と対応する位置に、マーク１３を付ける。【選択図】図２
