Large-diameter prestressed concrete-filled steel tube slide-resistant pile and construction method thereof
The invention relates to the technical field of slide-resistant piles, in particular to a large-diameter prestressed concrete-filled steel tube slide-resistant pile and a construction method thereof.The large-diameter prestressed concrete-filled steel tube slide-resistant pile is characterized in that a plurality of steel tubes are installed between a landslide body and a slide bed, prestressed structures are arranged on the inner walls of the steel tubes, and concrete core piles are poured in the steel tubes; the prestressed structure comprises a small-diameter steel pipe, a prestressed steel strand, an anchorage device and an anchorage pier support; an anchorage pier support is welded to the inner wall of the steel pipe, a fixed anchorage device is arranged on one side of the anchorage pier support, a small-diameter steel pipe is fixed to the other side of the anchorage pier support, a plurality of prestressed steel strands are fixed through the anchorage device, and the prestressed steel strands penetrate through the small-diameter steel pipe. The multiple steel pipes are sequentially and correspondingly installed through centering devices arranged on the steel pipes to form the large-diameter prestressed concrete-filled steel tube slide-resistant pile. The prestressed concrete-filled steel tube slide-resistant pile achieves the purposes of being large in rigidity, high in bearing capacity, environmentally friendly and economic.
本发明涉及抗滑桩技术领域,具体为一种大直径预应力钢管混凝土抗滑桩及其施工方法,包括在滑坡体和滑床之间安装若干钢管,钢管内壁设置预应力结构,并在钢管内浇注混凝土芯桩,所述预应力结构包括小直径钢管、预应力钢绞线、锚具和锚墩支座;所述钢管内壁焊接有锚墩支座,锚墩支座一侧为固定锚具,另一侧固定有小直径钢管,通过锚具固定有若干预应力钢绞线,且使得若干预应力钢绞线贯穿于小直径钢管,若干钢管通过其上设置的对中装置依次对应安装形成大直径预应力钢管混凝土抗滑桩。本发明使得预应力钢管混凝土抗滑桩达到刚度大,承载力高,绿色环保,经济效果的目的。
