UNDERWATER WORK MACHINE AND UNDERWATER EXCAVATION METHOD
To propose an underwater work machine and an underwater excavation method which can excavate (rock-break) bedrock at the bottom of water.SOLUTION: An underwater excavation method includes a work machine lowering process in which an underwater work machine 1 is lowered along a shaft 2 whose lower end is supported on the water bottom GL and whose upper part is supported on a work vessel B, and a water bottom excavation process in which the water bottom GL is excavated by the underwater work machine 1. A down-the-hole hammer 4 is mounted on an arm 14 of the underwater work machine 1, and the water bottom excavation process includes operation to form borehole H on the water bottom GL by the down-the-hole hammer 4.SELECTED DRAWING: Figure 1
【課題】水底の岩盤を掘削（割岩）可能な水中作業機および水中掘削工法を提案する。【解決手段】下端が水底Ｇｌに支持されて、上部が作業船Ｂに支持されたシャフト２に沿って水中作業機１を下降させる作業機下降工程と、水中作業機１により水底ＧＬを掘削する水底掘削工程とを備える水中掘削工法である。水中作業機１のアーム１４には、ダウンザホールハンマ４が取り付けられており、水底掘削工程は、ダウンザホールハンマ４により水底ＧＬに掘削孔Ｈを形成する作業を含んでいる。【選択図】図１
