Abstract

PROBLEM TO BE SOLVED: To enable an increase in in-ground vertical bearing capacity of a hydraulic solidification material liquid-substituted column and an increase in surface friction against fill-up ground and push-in bearing capacity.SOLUTION: An upper part of an excavation rod, in which an excavation head having a discharge opening for a hydraulic solidification material liquid is connected to a lower end, is formed into an inverted cone-shaped part having an outside diameter increased upward from below, and a spiral blade is fixed to an outer peripheral surface of the inverted cone-shaped part.

【課題】水硬性固化材液置換コラムの地盤内における鉛直方向支持力の向上と、盛土地盤に対する周面摩擦力、押し込み支持力の増大を可能にする。【解決手段】水硬性固化材液の吐出口を有する掘削ヘッドを下端に接続した掘削ロッドの上方部が、下方より上方に行くにつれて外径が大きくなる逆円錐部となり、該逆円錐部の外周面にスパイラル翼が固設されている。【選択図】図１
