Construction process of PHC cement soil mixed composite pile
The invention discloses a construction process of a PHC cement soil mixed composite pile. The construction process comprises the following steps of (1) preparing for pre-burying of a cement soil mixed pile; (2) preparing materials required by the PHC cement soil mixed composite pile; and (3) adding a prestressed pipe pile to the soil mixed pile, performing pile forming, and performing static pressure forming on the PHC cement soil mixed composite pile formed by combining the cement soil mixed pile and the PHC high-strength prestressed pipe pile through a static pressure pile machine, so that the cement soil mixed pile and the PHC high-strength prestressed pipe pile (uplift square pile) are perfectly combined, the friction surface of the whole pile body is enlarged, the compressive strength (pulling resistance) of the pile body is increased, and the overall good pile forming effect is guaranteed. According to the construction process of the PHC cement soil mixed composite pile, the construction speed of composite pile forming is greatly increased, the precious construction period is shortened, a high-pressure spraying and mixing and rotary excavating integrated machine is replaced with a rotary excavating hole leading machine and a high-pressure spraying and mixing machine, the mechanical use efficiency is improved, and the overall practicability is improved.
本发明公开了一种PHC水泥土搅拌复合桩施工工艺，其步骤如下：步骤一：对水泥土搅拌桩的预埋做准备；步骤二：对PHC水泥土搅拌复合桩所需要材料进行制备；步骤三：对泥土搅拌桩内部加入预应力管桩并进行成桩，使用静压桩机对水泥土搅拌桩与PHC高强预应力管桩组合而成的PHC水泥土搅拌复合桩进行静压成型，从而使水泥土搅拌桩与PHC高强预应力管桩（抗拔方桩）的完美结合，从而扩大整个桩体的摩擦面，既而提高其抗压强度（抗拔强度），保证整体良好的成桩效果。该PHC水泥土搅拌复合桩施工工艺，极大的加快了复合成桩的施工速度，节省了宝贵的工期，且使用旋挖引孔机和高压喷射搅拌机代替高压喷射搅拌旋挖一体机，机械使用效率提高，增加了整体实用性。
