Variable-diameter pile forming device
The invention relates to a variable-diameter pile forming device. The variable-diameter pile forming device comprises a plurality of longitudinal bar assemblies arranged in the circumferential direction and spiral stirrups spirally wound around the longitudinal bar assemblies in the vertical direction. The variable-diameter pile forming device further comprises a distraction structure used for driving the longitudinal bar assemblies to be away from one another so as to expand the diameter. The longitudinal bar assembly comprises a plurality of longitudinal bars arranged in the vertical direction and further comprises longitudinal bar connectors located between any two adjacent longitudinal bars, and the ends of the longitudinal bars are inserted into the corresponding longitudinal bar connectors in a matched and sliding mode in the vertical direction. The longitudinal bar connectors are located at the intersecting positions of the spiral stirrups and the longitudinal bar assemblies, the spiral stirrups penetrate through the longitudinal bar connectors and can slide relative to the longitudinal bar connectors, and the expanding structure drives the longitudinal bar assemblies to be away from one another so that diameter expanding can be conducted. The spiral stirrups slide relative to the longitudinal bar connectors and drive the longitudinal bar connectors to move in the vertical direction so that the depth of the longitudinal bars inserted into the longitudinal bar connectors can be increased, and then the length of the longitudinal bar assembly can be shortened.
本发明涉及一种可变径成桩装置，可变径成桩装置包括周向排布的多个纵筋组件以及沿上下方向螺旋绕设在各纵筋组件上的螺旋型箍筋；可变径成桩装置还包括用于驱动各纵筋组件相互远离以进行扩径的撑开结构；所述纵筋组件包括沿上下方向排布的多个纵筋，还包括位于任意相邻两纵筋之间的纵筋接头，所述纵筋的端部沿上下方向适配地滑动插装至对应的纵筋接头中；所述纵筋接头位于螺旋型箍筋、纵筋组件的相交位置处，所述螺旋型箍筋贯穿各纵筋接头且可相对于纵筋接头滑动，所述撑开结构驱动各纵筋组件相互远离以进行扩径时，所述螺旋型箍筋相对于纵筋接头滑动且带动纵筋接头沿上下方向移动以加大纵筋插入纵筋接头中的深度进而缩短纵筋组件的长度。
