Anti-freezing and anti-pulling pile body structure in cold region
The embodiment of the invention provides an anti-freezing and anti-pulling pile body structure in a cold region. The pile body structure sequentially comprises a pile body section, an anchoring section and a pile end from top to bottom, and the anchoring section comprises an anchoring section pile body, an anchoring sheet, a rotating shaft, a spring and a through hole. The anchoring section is arranged, the anchoring section is provided with the anchoring sheet and the spring, the lower end of the anchoring sheet is hinged to the pile body, the upper end of the anchoring sheet compresses the spring in the driving process, when the pile body is frozen and pulled, the anchoring sheet is opened, pile side soil enters a gap between the anchoring sheet and the anchoring section pile body, uplift resistance is provided for the pile, and pile foundation freezing and pulling are restrained. After a certain freezing and pulling amount is generated in the first cold season, the anchoring sectionobtains enough pulling resistance, the pile foundation does not continue to be pulled upwards any more, and accumulated freezing and pulling diseases are controlled.
本发明实施例提供了一种寒区抗冻拔桩体结构，桩体结构从上至下依次为：桩身段、锚固段和桩端，锚固段包括：锚固段桩身、锚固片、转动轴、弹簧和贯穿孔。本发明通过设置锚固段，锚固段装有锚固片和弹簧，锚固片下端和桩身铰接，锚固片上端在打入时压紧弹簧，当桩体冻拔时，锚固片张开，桩侧土体进入锚固片和锚固段桩身之间的空隙，为桩提供上拔阻力，抑制桩基冻拔。在第一个冷季产生一定的冻拔量后，锚固段获得足够的上拔阻力，桩基不再继续上拔，累积冻拔病害得到控制。
