The invention discloses a construction method of a cast-in-place pile. The construction method comprises the following steps: burying a steel casing; impact hole forming is conducted, specifically, when the hole forming depth is above the bottom of the steel casing, the hammering height is set to be 1-2 m, when the hole forming depth reaches the bottom of the steel casing, the hammering height is reduced to 0.4-0.6 m, and when the hole forming depth reaches 3-4 m below the bottom of the steel casing, the hammering height is increased to 2-3.5 m; mounting and placing a reinforcement cage: connecting the reinforcement cage with the steel casing, and fixing the reinforcement cage at the central position of the steel casing; a supporting structure is arranged at the bottom of the guide pipe and used for supporting the guide pipe, and a gap of 30-50 cm is reserved between the bottom of the guide pipe and the bottom of the pile hole; concrete is poured into the pile hole through the guide pipe to manufacture the pile body, the gap between the bottom of the guide pipe and the bottom of the pile hole is filled with the concrete during concrete pouring, and the depth of the lower end of the guide pipe embedded in the concrete is larger than 1.0 m; and processing the pile head. The construction quality of the cast-in-place pile can be improved.
本发明公开了一种灌注桩施工方法，包括：埋设钢护筒；冲击成孔：当成孔深度在钢护筒底部之上时，锤击高度设定为1‑2m，当成孔深度达到钢护筒底部时，将锤击高度降低至0.4‑0.6m，达到钢护筒底部以下3‑4m时，将锤击高度提高至2‑3.5m；安装放置钢筋笼：将钢筋笼与钢护筒连接，将钢筋笼固定于钢护筒的居中位置；安装导管：导管底部设置有支撑结构，支撑结构用于支撑导管，并使导管底部与桩孔底部预留有30‑50cm的空隙；制作桩身：通过导管向桩孔内灌注混凝土以制作桩身，灌注混凝土时使混凝土填满导管底部与桩孔底部之间的空隙，且导管下端埋入混凝土的深度大于1.0m；处理桩头。本发明可以提高灌注桩的施工质量。
