TRIAL DIGGING METHOD
PROBLEM TO BE SOLVED: To improve work efficiency without damaging an underground buried object in 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. 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. At the trial digging work, the rock mass is excavated within a range in which the flexible member 7j of the tip part of the trial digging attachment 7 contacts with the underground buried object. By this constitution, at the trial digging work, work efficiency can be improved without damaging the underground buried object.SELECTED DRAWING: Figure 1
【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、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。試掘作業に際しては、試掘用のアタッチメント７の先端部の可撓性部材７ｊが地下埋設物に接触する範囲で地山の掘削を行うようにする。これにより、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ことができる。【選択図】図１
