METHOD AND DEVICE FOR MEASURING PILE PENETRATION AMOUNT
To provide a method for measuring a pile penetration amount which makes measuring work of a penetration amount easy regardless of weather.SOLUTION: A method for measuring a penetration amount of a pile rotating and penetrating into a ground performs: a preparation step of, when a pile 10 or a rod 10c connected with the pile 10 is an object to be wound, fixing an end of a linear body 20 such as a thread or a string to an outer peripheral surface of the object to be wound and holding the linear body 20 extended from the object to be wound at a lateral side of an installation position of the pile 10; a penetration step of, after the preparation step, making the pile 10 rotate and penetrate in an extended state of the linear body 20 and winding the linear body 20 supplied from the lateral side of the installation position around the outer peripheral surface of the object to be wound at approximately constant height; and a measurement step of measuring a length of the pile 10 in an axial direction about an area in which the outer peripheral surface of the object to be wound is wound with the linear body 20 in the preparation step.SELECTED DRAWING: Figure 2
【課題】杭の貫入量の測定方法において、天候に拘わらず貫入量の測定作業が容易な測定方法を提供する。【解決手段】地中に回転貫入する杭の貫入量の測定方法は、杭１０または杭１０に接続されたロッド１０ｃを巻付対象物とした場合、巻付対象物の外周面に糸又は紐などの線状体２０の端部を固定すると共に、杭１０の打設箇所の側方において巻付対象物から延ばした線状体２０を保持する準備ステップと、準備ステップ後に、線状体２０を張った状態で杭１０を回転貫入させて、打設箇所の側方から繰り出される線状体２０を略一定の高さで巻付対象物の外周面に巻き付けさせる貫入ステップと、貫入ステップにおいて巻付対象物の外周面に線状体２０が巻き付けられた区間について、杭１０の軸方向の長さを測定する測定ステップとを実行する。【選択図】図２
