Long spiral guide hole static pressure composite carrier rammed prestressed hollow pipe pile construction method
The invention discloses a construction method of a long spiral guide hole static pressure composite carrier rammed prestressed hollow pipe pile, and relates to the technical field of geological engineering construction. Comprising the steps of S1, construction preparation, S2, drilling of a long screw pile machine, S3, cleaning of the inner wall of a prefabricated hollow pipe pile, S4, mounting of a pile bottom end sealing device, S5, pressing of a static pressure pile machine into the pipe pile, S6, three-strike penetration control tamping filler, S7, mounting of a pile body reinforcement cage, S8, pile cap reinforcement and formwork construction and S9, concrete pouring. According to the construction method of the long spiral guide hole static pressure composite carrier rammed prestressed hollow pipe pile, the prefabricated hollow pipe pile serves as a construction pile casing and also serves as a bearing component, the long spiral guide hole is adopted to assist a static pressure pile machine in construction, and the reverse construction method of the long spiral guide hole static pressure composite carrier rammed prestressed hollow pipe pile in the complex geology is formed. The problems of a traditional construction method are solved, construction is easy and convenient, the application range is wide, the pile forming quality is good, the single-pile bearing capacity is greatly improved, and the construction cost and the construction period are greatly reduced.
本发明公开了一种长螺旋引孔静压复合载体夯扩预应力空心管桩施工方法，涉及地质工程施工技术领域，包括S1施工准备、S2长螺旋桩机钻孔、S3清理预制空心管桩内壁、S4安装桩底端封闭装置、S5静压桩机压入管桩、S6三击贯入度控制夯实填料、S7安装桩身钢筋笼、S8桩帽钢筋及模板施工、S9浇筑混凝土。该长螺旋引孔静压复合载体夯扩预应力空心管桩施工方法，将预制空心管桩既作为施工护筒，又作为承载构件，采用长螺旋引孔辅助静压桩机施工，形成了复杂地质长螺旋引孔静压复合载体夯扩预应力空心管桩逆作施工工法，解决了传统施工工法的难题，施工简单便捷，适用范围广，成桩质量好，单桩承载力大幅提高，施工成本与工期大幅降低。
