JOINING STRUCTURE OF ROD OF GROUND SURVEY DEVICE
To provide a joining structure of a rod of a ground survey device capable of easily and safely attaching and detaching the rod even in a state where a load in a vertical direction acts on the rod.SOLUTION: A joining structure of a rod of a ground survey device in which the rod is penetrated into the ground when the target ground is investigated includes: a joining member 4 whose cap part 41 covering an upper end jig 221 of the rod 22 is provided at the lower end; and a pin part 5 which is inserted in a direction orthogonal to an axial direction of the rod so as to be engaged with the cap part and the upper end jig. This pin part is arranged along a pair of concave parts 221a provided on the peripheral surface of the upper end jig.SELECTED DRAWING: Figure 1
【課題】ロッドに鉛直方向の荷重が作用した状態であっても、簡単かつ安全にロッドの着脱を行うことができる地盤調査装置のロッドの接合構造を提供する。【解決手段】対象地盤を調査する際に地盤にロッドを貫入させる地盤調査装置のロッドの接合構造である。そして、ロッド２２の上端治具２２１を覆うキャップ部４１が下端に設けられた接合部材４と、ロッドの軸方向に直交する方向に向けて、キャップ部と上端治具に係合するように挿し込まれるピン部５とを備えている。このピン部は、上端治具の周面に設けられた一対の凹部２２１ａに沿って配置される。【選択図】図１
