DRILLING DEVICE, DRILLING METHOD, AND GUIDE DEVICE
PROBLEM TO BE SOLVED: To precisely press a casing in a pressed-in body such as the foundation.SOLUTION: A drilling device 1 includes: a work barge 2 which floats on a water surface; a casing pressing-in device 3 which is installed on the work barge 2 and presses a cylindrical casing 4 in a foundation 10 on the water bottom; a first guide device 7 which is so provided on a top surface of the foundation 10 on the water bottom as to be positioned in the casing 4 to be pressed in, and restricts a horizontal movement of the casing 4; a second guide device 8 which is so arranged as to come into contact with an outer peripheral surface of the casing 4, and restricts the horizontal movement of the casing 4; and a hammer grab 6 which excavates a part, positioned in the pressed-in casing 4, of the foundation 10 on the water bottom. The first guide device 7 has a columnar weight 21 having a smaller diameter than the casing 4. The second guide device 8 has a vertical four-layered structure, and is composed of H beams 31-42.
【課題】地盤等の被圧入物にケーシングを精度良く圧入する。【解決手段】削孔装置１は、水面上に浮かぶ作業台船２と、作業台船２に設置されて水底の地盤１０に円筒状のケーシング４を圧入するケーシング圧入装置３と、圧入されるケーシング４内に位置するように水底の地盤１０の表面上に設けられてケーシング４の水平移動を規制する第１ガイド装置７と、ケーシング４の外周面に接触可能なように配置されてケーシング４の水平移動を規制する第２ガイド装置８と、水底の地盤１０のうち圧入されたケーシング４内に位置する部分を掘削するハンマーグラブ６と、を備える。第１ガイド装置７は、ケーシング４より小径の円柱状の重錘２１を備える。第２ガイド装置８は上下４層構造であり、Ｈ形鋼３１〜４２により構成される。【選択図】図４
