Post-grouting PHC pipe pile and construction method thereof
The post-grouting PHC pipe pile comprises an upper-section PHC pipe pile body, a lower-section PHC pipe pile body, an upper-section grouting pipe body and a lower-section grouting pipe body, the upper-section grouting pipe body and the lower-section grouting pipe body are correspondingly arranged in the upper-section PHC pipe pile body and the lower-section PHC pipe pile body, the bottom end of the upper-section PHC pipe pile body is coaxially and fixedly connected with an annular disc I, and the top end of the lower-section PHC pipe pile body is coaxially and fixedly connected with an annular disc II. An annular grouting groove is formed in the butt joint portion of the annular disc I and the annular disc II, the lower end of the upper-section grouting pipe is fixed to the annular disc I and communicated with the annular grouting groove, the upper end of the lower-section grouting pipe is fixed to the annular disc II and communicated with the annular grouting groove, the bottom end of the lower-section PHC pipe pile is fixedly connected with a pile tip, and a grouting hole is formed in the pile tip. The lower end of the lower section grouting pipe is fixed to the pile tip and communicated with the grouting hole, and the grouting hole is provided with a plug which can be jacked open by grouting pressure. The upper end of the upper section grouting pipe is fixedly connected with the fixing ring; the construction efficiency can be improved, and the construction quality is improved.
本发明公开了一种后注浆PHC管桩及其施工方法，包括上节PHC管桩、下节PHC管桩、对应设置于上节PHC管桩和下节PHC管桩内的上节注浆管与下节注浆管，上节PHC管桩底端同轴固定连接有环形盘Ⅰ，下节PHC管桩顶端同轴固定连接有环形盘Ⅱ，并于环形盘Ⅰ与环形盘Ⅱ的对接部设有环形注浆槽，上节注浆管下端固定于环形盘Ⅰ并与环形注浆槽连通，下节注浆管上端固定于环形盘Ⅱ并与环形注浆槽连通，下节PHC管桩底端固定连接有桩尖，桩尖上设有注浆孔，下节注浆管下端固定于桩尖并与注浆孔连通，注浆孔设有可被注浆压力顶开的堵头；还包括固定环，上节注浆管上端与固定环固定连接；能够提高施工效率，提升施工质量。
