UNDERWATER BEDROCK EXCAVATION METHOD
PROBLEM TO BE SOLVED: To provide an underwater bedrock excavation method capable of more efficiently excavating an underwater bedrock such as dam lake bottom.SOLUTION: A underwater bottom is excavated by a down-the-hole hammer and a steel pipe pile 4 is erected. A work floor 5 is installed by making the steel pipe pile 4 support the work floor. The steel pipe piles 4 are erected and the work floors 5 are installed sequentially by using the work floor 5 installed previously, and a landing pier 1 is installed in an excavation target area R2. Multiple drilling holes 3 are drilled without overlapping on a bedrock in the excavation target area R2 from the landing pier 1 and the bedrock on which the multiple drilling holes 3 are drilled is excavated by an excavator. The work floors 5 and the steel pipe piles 4 are sequentially removed and multiple drilling holes 3 are drilled on the bedrock below the work floor 5 without overlapping and the bedrock is excavated by the excavator.SELECTED DRAWING: Figure 2
【課題】より効率的にダム湖底などの水底の岩盤を掘削することを可能にした水底の岩盤掘削方法を提供する。【解決手段】ダウンザホールハンマーで掘削するとともに鋼管杭４を建て込み、鋼管杭４に支持させて作業床５を設置し、先行設置した作業床５を用いて順次鋼管杭４の建て込み、作業床５の設置を行って掘削対象領域Ｒ２に桟橋１を設置する。そして、桟橋１から掘削対象領域Ｒ２の岩盤に複数の掘削孔３をラップさせずに穿設し、該複数の掘削孔３を穿設した岩盤を掘削機で掘削するとともに、順次作業床５及び鋼管杭４を撤去しながら作業床５の下方の岩盤に複数の掘削孔３をラップさせずに穿設し掘削機で掘削してゆく。【選択図】図２
