    The invention discloses a construction method for a combined pile of steel pipe piles and steel sheet piles. The construction method comprises the steps that after the m

    steel pipe pile is constructed to a preset height, a positioning sleeve is installed; the m steel sheet pile is hoisted, and the steel sheet piles are vertically pressed downwards after the perpendicularity of the steel sheet piles is adjusted, so that the steel sheet piles are at the preset height; a high-pressure water jet cutter is installed in the (m + 1) steel pipe pile, the steel pipe piles are vertically pressed downwards to the preset height after the perpendicularity of the steel pipe piles is adjusted, and in the construction process of pressing the steel pipe piles downwards, soil below the steel pipe piles is cut through the high-pressure water jet cutter; and the steps are repeated till all the steel pipe piles and all the steel sheet piles are constructed. The positioning sleeve is based on the constructed steel pipe piles, the straightness of the subsequent steel sheet piles and the steel pipe piles is controlled, and the construction method has the advantages of being simple in structure, convenient to operate and easy to popularize. The high-pressure water jet cutter can enable the soil to form slurry through high-pressure water flow, the pile sinking difficulty is lowered, and the construction safety is improved by controlling the pressure in a cavity to be within an allowable range.

    本发明公开了一种钢管桩和钢板桩的组合桩施工方法，包括步骤：第m根钢管桩施工至预定高度后，安装定位套筒；起吊第m根钢板桩，调整钢板桩垂直度后垂直下压钢板桩，使钢板桩至预设高度；在第m+1根钢管桩内安装高压水刀，调整钢管桩垂直度后垂直下压钢管桩至预设高度，在下压钢管桩施工中，通过高压水刀切割钢管桩下方土体；重复上述步骤，直至所有钢管桩及钢板桩均完成施工。定位套筒以已施工钢管桩为基础，控制后续的钢板桩和钢管桩的直线度，具有结构简单、操作方便、易于推广的优点。高压水刀能够通过高压水流使土体形成泥浆液，降低沉桩难度，通过控制腔室内的压力处于允许范围内，从而提高施工安全性。
