Rotary excavating cast-in-place pile under miscellaneous fill high backfill geological condition
The invention discloses a rotary excavating cast-in-place pile under miscellaneous fill high backfill geological conditions, the rotary excavating cast-in-place pile comprises a reinforcement cage and a concrete structure body, the reinforcement cage is of a cylindrical structure and comprises stirrups and a plurality of main reinforcements, and the stirrups are arranged around the vertically arranged main reinforcements; a cross arm is arranged at the top of the reinforcement cage, and the two ends of the cross arm are fixed to the side wall of an opening of the pile hole. The top side of the pile hole is further provided with a hole opening pile casing, a plurality of inserting holes are further formed in the bottom of the side wall of the hole opening pile casing in the circumferential direction, and convex-tooth-shaped partition pieces are arranged in the inserting holes in an inserted mode. The bottom of the reinforcement cage extends into a foundation pile hole, a gap is formed between a reinforcement at the bottom of the reinforcement cage and the bottom of the pile hole, the top of a main reinforcement of the reinforcement cage is located in the hole opening pile casing, and the concrete structural body is poured into the pile hole and the pile casing and wraps the reinforcement cage. Through the structural design of the rotary excavating cast-in-place pile, the pile forming quality and the pile forming efficiency of the rotary excavating cast-in-place pile are guaranteed.
本发明公开了一种杂填土高回填地质条件下的旋挖灌注桩，所述旋挖灌注桩包括：钢筋笼和混凝土结构体，所述钢筋笼为圆柱状结构，包括箍筋和若干主筋，所述箍筋绕各竖向设置的主筋设置；所述钢筋笼顶部设有横担，所述横担两端固定于桩孔的开口处的侧壁之上；所述桩孔的顶侧还设有孔口护筒，且所述孔口护筒的侧壁底部周向上还设有若干插接孔，各接插孔内插设有凸齿状分隔件；所述钢筋笼底部伸入地基桩孔内，且所述钢筋笼底部钢筋与桩孔的底部间有间隙，所述钢筋笼的主筋顶部位于所述孔口护筒内，所述混凝土结构体被浇筑于桩孔和护筒内，并完成对钢筋笼的包裹。通过本旋挖灌注桩的结构设计保证了旋挖灌注桩的成桩质量和成桩效率。
