Anti-freezing and anti-pulling expanded bore pile structure and construction method thereof
The invention relates to the technical field of towers, and discloses an anti-freezing and anti-pulling expanded-base pile structure and a construction method thereof. The anti-freezing and anti-pulling expanded-base pile structure comprises a framework stand column, an umbrella rib structure and a sliding block, the top end of the framework stand column is used for being connected with a pile column, the framework stand column is axially and movably sleeved with the sliding block, and the umbrella rib structure comprises a supporting rod and a connecting rod, the bottom ends of the supporting rods are rotationally assembled on the framework stand column, connecting rods are connected between the supporting rods and the sliding blocks, one ends of the connecting rods are hinged to the supporting rods, and the other ends of the connecting rods are hinged to the sliding blocks. When a tower foundation is built in a frozen soil layer, a constructor arranges the anti-freezing pulling bottom column structure at the bottom of a pile hole, the umbrella rib structure is embedded into a soil body to play a role of a pre-embedded rib, and when the pile foundation is influenced by the effect of freezing pulling force, the umbrella rib structure and the framework stand column can provide downward pulling resistance to weaken the freezing pulling phenomenon; the requirement for the production technology is low, assembly line batch production is facilitated, the manufacturing cost is low, the construction difficulty is small, and construction is simplified.
本发明涉及杆塔技术领域，公开了一种抗冻拔扩底桩结构及其施工方法，抗冻拔扩底桩结构包括骨架立柱、伞骨结构和滑动块，骨架立柱的顶端用于与桩柱连接，滑动块轴向活动套装在骨架立柱上，伞骨结构包括支撑杆和连接杆，支撑杆的底端转动装配在骨架立柱上，各支撑杆与滑动块之间均连接有连接杆，连接杆的一端与支撑杆铰接、另一端与滑动块铰接。在冻土层中建造杆塔基础时，施工人员将该抗冻拔底柱结构布置在桩孔的底部，伞骨结构嵌入土体中起到了预埋筋的作用，桩柱基础受到冻拔力作用影响时，伞骨结构以及骨架立柱可以提供向下的抗拔力，减弱冻拔现象；对生产工艺的要求较低，便于流水线批量生产，制造成本低，施工难度较小，简化施工。
