| description | To provide an exploration method for identifying the internal structure of obstacles in front of an excavating machine, using the machine.SOLUTION: A forward exploration method using an excavating machine, according to the present invention is provided. The method includes: a jetting step of jetting abrasive jet water containing abrasives toward an obstacle ahead in an excavation direction from a jet nozzle provided on a cutter face plate while rotating the cutter face plate; and a detection step for detecting reflection sounds from the obstacle due to jetting of abrasive jet water.SELECTED DRAWING: Figure 1
【課題】 掘進機において、障害物の内部構造を特定する。【解決手段】 掘進機の前方探査方法が提供される。この方法は、カッタ面板を回転させつつ、カッタ面板に設けられた噴射ノズルから研磨材を含むアブレイシブジェット水を掘進方向前方に向けて噴射する噴射工程と、アブレイシブジェット水の噴射に基づく反射音を検出する検出工程と、を備えている。【選択図】図１ |
