Uplift pile and construction method thereof
The uplift pile comprises a pile end carrier and a pile body, the pile end carrier and the pile body are of an integrated structure formed in an underground pile hole through concrete pouring, a single pile body is formed, a reinforcement cage is arranged in the single pile body, and a plurality of radial framework structures are rotationally installed on the surface of the reinforcement cage; the radial consolidation structure comprises a connecting sleeve and a radial rib, the connecting sleeve is rotatably mounted on the surface of the reinforcement cage, the radial rib is slidably inserted in the connecting sleeve, and the concrete grout wraps the surface of the radial rib to form an anti-pulling bulge integrated with the single pile body. The pile body is provided with the anti-pulling protrusions, the anti-pulling protrusions are embedded into peripheral soil, the side resistance of the pile is improved, and therefore the side resistance bearing capacity of the pile body is improved, due to the fact that the anti-pulling protrusions are formed while the pile body is poured underground, the structural integrity is high, convenience is provided for increasing the size of the anti-pulling protrusions for meeting the requirement for the anti-pulling bearing capacity, and the anti-pulling bearing capacity is improved. The construction problem that in the prior art, protrusions are attached to the surfaces of prefabricated uplift piles, and the uplift piles are difficult to drive underground is solved.
本发明公开了一种抗拔桩，包括桩端载体和桩体，桩端载体和桩体，是在地下的桩孔内通过混凝土浇筑成一体结构，构成一个的单桩体，所述单桩体内设置有钢筋笼，钢筋笼的表面转动安装有若干个径向骨架结构，径向固结结构包括连接套和径向筋，连接套转动安装在钢筋笼的表面，径向筋滑动插设在连接套内，混凝土浆液包裹在径向筋的表面，形成与单桩体为一体的抗拔凸起。该桩身设置有抗拔凸起，通过抗拔凸起嵌入周边土壤内，提高桩侧侧阻，从而提高了桩身侧阻承载力，由于抗拔凸起在地下浇筑桩身同时形成的，结构整体性强，为满足抗拔承载力需要增大抗拔凸起尺寸提供便利，解决了现有技术中预制抗拔桩表面附带凸起，难以打入地下的施工难题。
