Rotary excavating pile structure and construction method thereof
The invention relates to a rotary excavating pile structure and a construction method thereof, and relates to the technical field of rotary excavating piles. The rotary excavating pile structure comprises a reinforcement cage, a straight pipe section made of reinforced concrete and a concrete body formed by pouring concrete, wherein the straight pipe section is sleeved with an accumulated soil falling prevention device used for preventing loosened soil from directly falling, a plurality of outer supporting ribs distributed around the axis of the straight pipe in the circumferential direction are arranged on the outer wall of the straight pipe section, the accumulated soil falling prevention device is arranged on the upper end face of each outer supporting rib in a lap joint mode and connected with the outer wall of the straight pipe section in an abutting mode, and a pull rope is arranged on the accumulated soil falling prevention device. The rotary excavating pile structure has the effect of reducing the use influence of the accumulated soil falling prevention device.
本发明涉及一种旋挖桩结构及其施工方法，涉及旋挖桩技术领域，其包括钢筋笼、由钢筋砼制成的直管段以及由混凝土浇筑形成的砼体，直管段上套设有用于防止松土直接下落的积土止落装置，直管段的外壁上设置有若干道环直管的轴线周向排布的外支撑筋，积土止落装置搭在各件外支撑筋的上端面且与直管段的外壁抵触连接，积土止落装置上设置有拉绳；本发明具有降低积土止落装置使用影响的效果。
