Post-grouting prestressed pipe pile with reusable grouting pipe and construction method
The invention discloses a post-grouting prestressed pipe pile with a reusable grouting pipe and a construction method, and relates to the technical field of grouting, the post-grouting prestressed pipe pile comprises a prestressed pipe pile, a plurality of PVC sleeves penetrating through the prestressed pipe pile are arranged in the circumferential direction of the prestressed pipe pile, and a grouting valve is arranged at the tail end of each PVC sleeve; a post-grouting pipe is coaxially arranged in the PVC sleeve and can trigger the grouting valve to conduct grouting. The PVC sleeve is preset in the prestressed pipe pile and is matched with the grouting valve, so that the bearing capacity of the prestressed pipe pile is improved, and the construction efficiency can be improved.
本发明公开了一种注浆管可重复利用的后注浆预应力管桩及施工方法，涉及注浆技术领域，包括预应力管桩，所述预应力管桩周向内置多个贯穿其中的PVC套管，PVC套管末端设有注浆阀；PVC套管内同轴设置后注浆管，后注浆管能够触发注浆阀以进行注浆。本发明通过在预应力管桩内预设PVC套管，并配合注浆阀，提高预应力管桩的承载力，并且能够提高施工效率。
