CORE COLLECTING DEVICE, BORING DEVICE AND METHOD OF COLLECTING CORE
To provide a core collecting device capable of acquiring data for examining the accuracy of a collected core, a boring device using the core collecting device, and a method of collecting a core.SOLUTION: A core collecting device is detachable to one end of a rod of a boring device, and includes a tubular core barrel having a core collecting portion therein for collecting the core of the ground, and a first displacement meter for measuring the displacement of the core entering the core collecting portion. A first displacement gauge is a wire type displacement gauge in which the wire advances and retracts in a direction substantially parallel to an axis of the core barrel in the core collecting portion, and in which a tip of the wire is provided with a contact portion with which the core is in contact. The contact portion includes a contact portion main body and a pressing portion. The pressing portion is provided on the side periphery of the contact portion main body so that the contact portion presses the inner surface of the core barrel and the contact portion is movable in the axial direction of the core barrel inside the core barrel.SELECTED DRAWING: Figure 1
【課題】採取したコアの精度を検討するためのデータを取得することができるコア採取装置、これを用いたボーリング装置およびコアの採取方法を提供する。【解決手段】コア採取装置は、ボーリング装置のロッドの一端に着脱可能であり、地盤のコアを採取するコア採取部を内部に有する管状のコアバーレルと、コア採取部に進入するコアの変位を計測する第一の変位計と、を備え、第一の変位計は、ワイヤがコア採取部においてコアバーレルの軸と略平行な方向に進退するワイヤ式変位計であり、ワイヤの先端に、コアが接触する接触部を備え、接触部は、接触部本体と、押圧部と、を備え、押圧部は、接触部がコアバーレルの内面を押圧し、かつ接触部がコアバーレルの内部でコアバーレルの軸方向に移動可能となるように、接触部本体の側周に設けられている。【選択図】 図１
