Post-grouting composite pile and construction method
The invention relates to the technical field of building foundation construction, and discloses a post-grouting composite pile and a construction method, the post-grouting composite pile comprises a post-grouting precast pile and a guider, a post-grouting precast pile body is provided with multiple layers of grouting holes in the axial direction, check valves are correspondingly installed at the positions of the grouting holes, and a stop-grouting plug is in sliding fit with the post-grouting precast pile and the guider. The guider is used for being matched with the check valve to conduct pressure grouting, the guider and the post-grouting precast pile are coaxially arranged, the guider is fixedly connected with the top of the post-grouting precast pile, and a pile body supporting disc and a pile body chassis are arranged on the peripheral side of the post-grouting precast pile; through the arrangement of the stop-grouting plug and the check valve, the pressure grouting mode during construction of the composite pile is achieved, it can be guaranteed that soil around the post-grouting precast pile is compacted and reinforced, the soil around the pile is combined with the post-grouting precast pile more tightly through compaction grouting, and the construction concentricity of the composite pile is guaranteed.
本发明涉及建筑基础施工技术领域，公开了一种后注浆复合桩及施工方法，后注浆预制桩和导向器，后注浆预制桩柱身沿轴向方向设置多层注浆孔，注浆孔处对应安装止逆阀，止浆塞与后注浆预制桩和导向器滑动配合，用于配合止逆阀进行压力注浆，导向器与后注浆预制桩同轴设置，与后注浆预制桩顶部固定连接，后注浆预制桩周侧设有桩身支盘和桩身底盘；本发明通过止浆塞以及止逆阀的设置，实现了复合桩在施工时的压力注浆方式，可以保证后注浆预制桩桩周土体压密、加强，桩周土通过压密注浆与后注浆预制桩结合更加紧密，保证复合桩施工的同心度。
