EXCAVATOR FOR SOIL CEMENT UNDERGROUND CONTINUOUS WALL, AND CONSTRUCTION METHOD USING THE SAME
To provide an excavator for soil cement underground continuous walls and a construction method using the same, capable of reducing the construction costs by improving the construction efficiency of soil cement underground continuous walls using a horizontal multi-spindle excavator and capable of improving the quality of soil cement underground continuous walls.SOLUTION: An excavator comprises a plurality of rotary cutters having a horizontal rotation axis at the lowest part of the excavator and excavates a ground downward by rotating the rotary cutters while in contact with the ground. The excavator comprises: an injection pipe for discharging an excavation injection material and/or a solidification material near the outer periphery of the middle part of the plurality of rotary cutters; a mud feeding pump having an upper port and a lower port and capable of transferring mixed soil that is a mixture of excavated soil excavated by the rotary cutter and the excavation injection material and/or the solidification material; and a mud feeding pipe connected to the lower port of the mud feeding pump and having a lower end near a top of the rotary cutter.SELECTED DRAWING: Figure 1
【課題】 水平多軸掘削機を用いたソイルセメント地中連続壁の施工性を向上させて施工コストを低く抑えるとともに、ソイルセメント地中連続壁の品質を向上させることが可能なソイルセメント地中連続壁用掘削機及びこれを用いた施工方法を提供すること。【解決手段】 水平に回転軸を有するロータリーカッターを掘削機の最下部に複数備え、ロータリーカッターを地盤に接触させた状態で回転させることにより、地盤を下方に掘削する掘削機であって、複数のロータリーカッターの中間部外周近傍に掘削注入材及び／又は固化材を吐出させる注入管と、ロータリーカッターにより掘削した掘削土と掘削注入材及び／又は固化材を混合した混合土を移送可能な、上部口及び下部口を有する送泥ポンプと、該送泥ポンプの下部口に接続され、ロータリーカッターの上部近傍に下端部を有する送泥パイプを備えることを特徴とする。【選択図】図１
