The invention discloses a high-pressure rotary-jet hole-leading static-pressure pile construction method. The method is characterized by comprising the following steps that S1, a static-pressure machine is used for driving a soil taking pipe to be inserted into a soil layer by a preset depth; S2, the soil taking pipe is taken out of the soil layer, a pile hole is reserved, and concrete is poured into the pile hole; S3, a spiral drilling machine and the pile hole are coaxially rotated, the concrete and the soil layer on the peripheral wall of the pile hole are mixed, and the rotating diameter of the spiral drilling machine is larger than the diameter of the pile hole; S4, a prefabricated pile is inserted into the mixture of the concrete and the soil layer through the static-pressure machine, and the inserting depth of the prefabricated pile is 1.1 times of the preset depth; and S5, the steps S1, S2, S3 and S4 are repeated, and the rest of static-pressure piles are constructed.
本发明的一种高压旋喷引孔静压桩施工方法，其特征在于，包括以下步骤，S1：利用静压机带动取土管插入到土层中的预定深度；S2：将取土管从土层中取出，留下桩孔，在桩孔中浇筑混凝土；S3：利用螺旋钻孔机与桩孔同轴转动，将混凝土与桩孔周壁的土层混合，螺旋钻孔机的转动直径大于桩孔的直径；S4：通过静压机将预制桩插入到混凝土和土层的混合物中，预制桩的插入深度为预定深度的1.1倍；S5:重复S1、S2、S3、S4，对其余的静压桩施工。
