EXCAVATOR, INSTALLATION METHOD OF EXCAVATOR, AND GROUND EXCAVATION METHOD
To provide an excavator capable of excavating a ground below a cutting edge part of a caisson skeleton with a simple structure.SOLUTION: An excavator 10 excavates a ground 2 below a cutting edge part 1b of a caisson skeleton 1 in a cylindrical shape vertically extending and installed in the ground. The excavator 10 comprises: a cradle 11 placed on the ground 2 positioned in the caisson skeleton 1 in a plane view; a body portion 12 supported on the cradle 11 and horizontally rotatable to the cradle 11; an arm 13 having an upper part pivotably supported on a side of the body portion 12 and extending downward from the upper part and allowing telescopic motion; a ground excavation portion 14 excavating the ground 2 arranged on a lower end part 13c of the arm 13; and a tilting device 15 tilting the arm 13 around a pivotal axis Q of the upper part of the arm 13 as a center.SELECTED DRAWING: Figure 5
【課題】簡易な構成でケーソン躯体の刃口部の下方の地盤を掘削する。【解決手段】掘削機１０は、上下方向に延びて地中に沈設される筒状のケーソン躯体１の刃口部１ｂの下方の地盤２を掘削するものである。掘削機１０は、平面視でケーソン躯体１内に位置する地盤２に載置される架台１１と、架台１１に支持されて架台１１に対して水平旋回可能な本体部１２と、本体部１２の一側に上部が枢支されてこの上部から下方に延び、かつ、伸縮可能であるアーム１３と、アーム１３の下端部１３ｃに設けられて地盤２を掘削する地盤掘削部１４と、アーム１３の上部の枢支軸Ｑを中心としてアーム１３を傾動させる傾動装置１５と、を備える。【選択図】図５
