Umbrella stand type uplift anchoring pile and construction method
The invention discloses an umbrella stand type anti-pulling anchoring pile and a construction method, the umbrella stand type anti-pulling anchoring pile comprises a flange plate, an anchor rod, a framework unit, a limiting unit and a movement limiting unit, an annular groove is formed in the circumferential surface of the flange plate, and the groove edge of one side of the annular groove expands outwards to form an abutting part; the anchor rod penetrates through the flange plate; the framework unit comprises a plurality of first anchoring ribs, the first anchoring ribs are arranged in the circumferential direction, one end of each first anchoring rib is an abutting end abutting against the abutting part, the other end of each first anchoring rib is a free end, and the abutting ends are smaller than the annular grooves; the limiting unit comprises an annular spring piece, a core rope and a plurality of return springs; the abutting end is provided with a through first through hole, the annular spring piece and the core rope penetrate through the first through hole to be connected with the first anchoring ribs in series, and the perimeter of the core rope is smaller than the outer diameter of the abutting part. The other end of the pull-back spring is connected with the first anchoring rib; and the free end can be folded or released by the movable limiting unit. The structure is simple, the uplift bearing capacity is high, and the expansion effect is good.
本申请公开一种伞架型抗拔锚固桩及施工方法，伞架型抗拔锚固桩包括：法兰盘、锚杆、骨架单元、限位单元和活动限制单元，其中，法兰盘周向表面开有环槽，环槽的一侧槽边向外扩张形成抵接部；锚杆穿过法兰盘；骨架单元包括多个第一锚固筋，多个第一锚固筋周向设置，第一锚固筋的一端为与抵接部抵接的抵接端，另一端为自由端，抵接端小于环槽；限位单元包括环形弹簧件、芯绳和多个回拉弹簧；抵接端设有贯通的第一通孔，环形弹簧件和芯绳穿过第一通孔以串联多个第一锚固筋，芯绳的周长小于抵接部外径；回拉弹簧一端与法兰盘顶端连接，另一端与第一锚固筋连接；活动限制单元能够收拢或释放自由端。本申请结构简单且抗拔承载力强、扩体效果好。
