Construction method of prestressed pipe pile
The invention relates to the technical field of pipe pile construction, in particular to a construction method of a prestressed pipe pile. The construction method includes the steps that S1, a site is leveled, and the surface of a soil layer in a designated area is compacted; S2, measuring and positioning are conducted, wherein the pile position of the pipe pile is lofted and marked; S3, the soil layer is stabilized, reinforcing piles (1) are arranged in the construction area, and meanwhile grouting reinforcement is conducted on an underground soil body around pile positions in a high-pressure grouting mode in cooperation with grouting equipment; S4, the pile positions are measured again, and the pile positions are corrected again in a manual measurement mode; and S5, pile sinking operation is conducted, specifically, the pipe pile is pressed into the ground from the marked pile position, and pile splicing is conducted section by section till the designed depth is reached. The construction method of the prestressed pipe pile has the advantage that the difficulty of constructing the pipe pile in a soil layer with relatively loose soil is reduced.
本申请涉及管桩施工的技术领域，尤其是涉及一种预应力管桩的施工方法，包括以下步骤，S1：平整场地，将指定区域内的土层表面压实；S2：测量定位，对管桩的桩位进行放样并做好标记；S3：稳固土层，在施工区域内设置加固桩(1)，同时配合注浆设备通过高压注浆的方式对桩位周围地下的土体进行注浆加固；S4：复测桩位，通过人工测量的方式重新校正桩位；S5：沉桩作业，将管桩由标记好的桩位压入地面，并逐节接桩，直至设计深度。本申请的优点是降低在土质较为松散的土层中施工管桩的难度。
