MOUNTING STRUCTURE FOR EXCAVATION BLADE OF STEEL PIPE PILE, ANNULAR EXCAVATION TOOL AND PRESS-IN METHOD FOR STEEL PIPE PILE
To make it possible to construct a steel pipe pile in the ground without causing scratches on surrounding piles.SOLUTION: A tip of a mounting structure 4 for an excavation blade of a steel pipe pile is provided with excavation blades 5 excavating the ground. In the excavation blade 5, a protruding dimension (a) to the outside of an outer peripheral surface of the steel pipe pile (a between-piles pipe 3) is within 3 mm. The steel pipe pile is, for example, the between-piles pipe 3 which has a diameter smaller than a main pile 2, for constituting a continuous wall by installing it between the main piles 2 arranged at intervals. The steel pipe pile can be constructed in the ground while making it close to the surrounding main piles 2 that have already been constructed without causing scratches on the main piles 2.SELECTED DRAWING: Figure 4
【課題】周囲の杭に疵を付けることなく、鋼管杭を地盤に施工できるようにする。【解決手段】先端に地盤を掘削する掘削刃５を設けた鋼管杭の掘削刃取り付け構造４であって、掘削刃５は、鋼管杭（杭間パイプ３）の外周面よりも外側への突出寸法ａが３ｍｍ以内である。この鋼管杭は、例えば間隔をあけて設置された本杭２同士の間に設置して連続壁を構成するための、本杭２よりも小径の杭間パイプ３であり、既に施工されている周囲の本杭２に疵を付けることなく、本杭２に近接させて地盤に施工できる。【選択図】図４
