BORING OPERATION VEHICLE AND BORING METHOD
To provide a boring operation vehicle and a boring method that can easily locate a boring drill to a boring position without any skill with simple configuration, and can accurately bore deep boring hole to a vertical direction with good stability, and also can bore the boring hole by using a hydraulic pump of back hoe.SOLUTION: A boring operation vehicle comprises a boring device 50 that is supported through a joint member 40 to an arm 25 of back hoe 20. The boring device comprises a leader 51, a rotary device 60, a down-the-hole hammer 70 where its upper end is connected to the rotary device, and a feeding device 80 where the rotary device and the down-the-hole hammer are feed-driven along the leader. The joint member includes a first axis 41 substantially parallel to an arm axis 25a and a second axis 44 substantially orthogonal to the first axis. The leader is coupled to the arm rotatably around the first axis 41 and the second axis by the joint member.SELECTED DRAWING: Figure 2
【課題】簡単な構成により、熟練を要することなく、削孔ドリルを削孔位置に容易に位置決めできるとともに、精度良く鉛直方向に安定性良く深い掘削孔を削孔でき、しかもバックホーの油圧ポンプを利用して掘削孔を削孔可能な削孔作業車及び削孔方法を提供する。【解決手段】バックホー２０のアーム２５に継手部材４０を介して支持された削孔装置５０を備え、削孔装置は、リーダ５１と、回転装置６０と、上端部が回転装置に接続されたダウンザホールハンマ７０と、回転装置及びダウンザホールハンマをリーダに沿って送り駆動する送り装置８０とを備え、継手部材は、アームのアーム軸２５ａと略平行な第１軸４１と、第１軸と略直交する第２軸４４とを有し、リーダは、継手部材により第１軸４１及び第２軸を中心として回動自在にアームに連結されている。【選択図】図２
