Prestressed prefabricated pipe pile mechanical drilling and grouting pile and pile forming method thereof
The invention discloses a prestressed prefabricated pipe pile mechanical drilling and grouting pile and a pile forming method thereof, relates to the technical field of pile foundation construction, and solves the technical problems of hard geological conditions, difficulty in piling and high bearing capacity of an existing prestressed prefabricated pipe pile. Hard plastic grouting pipes are bound to the two sides of the outer wall of the prestressed prefabricated pipe pile respectively, anchor slurry wrapping layers are poured on the periphery of the prestressed prefabricated pipe pile from bottom to top through the hard plastic grouting pipes, and a bottom sealing treatment layer is arranged at the bottom in a hole of the prestressed prefabricated pipe pile. The method is wider in application range, is suitable for geological conditions that rock strata are strong weathered slate, medium weathered slate, limestone, round gravel soil layers and the like, is low in manufacturing cost, saves engineering cost, is short in construction period, is convenient to construct, is higher in bearing capacity, is a grouting pile with the diameter of 700mm and the anchor slurry wrapping layer thickness of 50mm, and has a single-pile vertical bearing capacity limit value of 9500KN. And the national current maximum value record is broken.
本发明公开了一种预应力预制管桩机械钻孔注浆桩及其成桩工法，涉及桩基础施工技术领域，解决地质条件坚硬打桩困难以及现有预应力预制管桩高承载力的技术问题，包括预应力预制管桩，所述预应力预制管桩的外壁两侧分别捆绑硬塑注浆管，通过硬塑注浆管从下至上在预应力预制管桩的周边注浇有锚浆包裹层，该预应力预制管桩的孔内底部设置有封底处理层；本发明适用范围更广，适用岩层为强风化板岩、中风化板岩、灰岩、圆砾土层等地质条件，造价低廉，节省工程成本，施工工期短，施工便捷，承载力更强，直径为700mm的桩型，锚浆包裹层厚度为50mm的注浆桩，单桩竖向承载力极限值达到9500KN，打破了国家目前最高值记录。
