TRIAL DIGGING MEMBER AND TRIAL DIGGING DEVICE INCLUDING THE SAME
PROBLEM TO BE SOLVED: To improve work efficiency without damaging an underground buried object in a trial digging work.SOLUTION: A trial digging device 2 comprises a hydraulic backhoe 6, and a trial digging attachment 7 attached to a tip of an arm 6c of the backhoe. The trial digging attachment 7 comprises means for excavating a rock mass in a non-contact manner by spraying high-pressure water from its tip face, agitating and air-sucking excavated sediment, and transporting it from a trial digging site. An agitation member for agitating the excavated sediment is rotatably arranged in a cylinder body 7a of the attachment 7, and the hydraulic pressure of the backhoe 6 as a drive force of a hydraulic motor for the rotation of the agitation member is used. Furthermore, a flexible member 7j is arranged at a tip part of the steel-made cylinder body 7a constituting the trial digging attachment 7 so as to protrude from the tip part.SELECTED DRAWING: Figure 6
【課題】試掘作業において、地下埋設物に損傷を与えることなく、作業効率を向上させる。【解決手段】試掘装置２は、油圧式のバックホウ６と、そのアーム６ｃの先端に装着された試掘用のアタッチメント７とを備えている。試掘用のアタッチメント７は、その先端面から高圧水を噴射して非接触で地山を掘削するとともに、掘削土砂を撹拌し空気吸引して試掘現場から搬送する手段を備えている。また、アタッチメント７の筒体７ａの内部には、掘削土砂を撹拌する撹拌部材が回転可能な状態で設けられており、その回転のための油圧モータの駆動力としてバックホウ６の油圧が使用されている。さらに、試掘用のアタッチメント７を構成する鋼製の筒体７ａの先端部には、その先端部から突出するように可撓性部材７ｊが設けられている。【選択図】図６
