Long spiral guide hole static pressure composite carrier rammed prestressed pipe pile construction method
The invention discloses a long spiral guide hole static pressure composite carrier rammed prestressed pipe pile construction method, and relates to the technical field of geological engineering construction. S2, drilling by a long screw pile machine; s3, the inner wall of the prefabricated hollow pipe pile is cleaned; s4, a pile bottom end sealing device is installed; s5, pipe piles are pressed in through a static pile pressing machine; s6, the third-strike penetration degree is used for controlling the tamping filler; s7, mounting a pile body reinforcement cage; s8, pile cap reinforcing steel bars and formworks are constructed; and S9, pouring concrete. According to the long spiral guide hole static pressure composite carrier rammed prestressed pipe pile construction method, a prefabricated hollow pipe pile serves as a construction pile casing and also serves as a bearing component, a long spiral guide hole is adopted to assist a static pressure pile machine in construction, and the complex geology long spiral guide hole static pressure composite carrier rammed prestressed hollow pipe pile reverse construction method 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。
