FOREIGN MATTER IDENTIFICATION METHOD AND FOREIGN MATTER IDENTIFICATION DEVICE
PROBLEM TO BE SOLVED: To provide a foreign matter identification method and a foreign matter identification device which enable the kind of foreign matter present in the ground to be identified with high accuracy by a simple method.SOLUTION: The foreign matter identification method for identifying the kind of foreign matter present in the ground is provided that comprises: a first step of presetting, for each of known underground buried objects, a criterion deformation coefficient that serves as an evaluation criterion for identifying the kind of foreign matter; a second step of inserting a rod into a drilled hole reaching the foreign matter and bringing the tip of the rod into contact with the foreign matter, and then generating an impact load at the tip of the rod, measuring the load acting on the foreign matter and the displacement of the foreign matter resulting from the generated impact load, and calculating the measured deformation coefficient of the foreign matter on the basis of the displacement and the load; and a third step of comparing the measured deformation coefficient with the criterion deformation coefficient and identifying the kind of the foreign matter.SELECTED DRAWING: Figure 4
【課題】簡略な方法で精度よく地盤中に存在する異物の種類を識別することの可能な、異物識別方法および異物識別装置を提供する。【解決手段】地盤中に存在する異物の種類を識別する異物識別方法であって、既知の地中埋設物各々について、異物の種類を識別するための評価基準となる基準変形係数をあらかじめ設定する第１の工程と、前記異物に到達する削孔にロッドを挿入して先端を前記異物に接触させた後、該ロッドの先端に衝撃荷重を発生させるとともに、これにより生じる前記異物に作用する荷重と前記異物の変位を測定し、該変位と前記荷重とに基づいて、前記異物の実測変形係数を算出する第２の工程と、該実測変形係数と前記基準変形係数とを比較し、前記異物の種類を識別する第３の工程と、を備えることを特徴とする。【選択図】図４
