Deep foundation pit uplift pile anchoring structure and construction method thereof
The invention relates to a deep foundation pit uplift pile anchoring structure and a construction method thereof. The anchoring structure comprises a mounting piece, a hoop and a concrete layer. The mounting piece comprises a sleeve fixedly arranged at the lower end of the uplift pile in a sleeving manner and a stress diffusion piece, and the stress diffusion piece is fixedly mounted at the upper end of the sleeve; the hoop is tightly hooped outside the sleeve and abuts against the bottom of the stress diffusion piece. And the concrete layer is formed by pouring concrete at the bottom of the foundation pit. The uplift pile and the concrete layer are anchored through the sleeve structure and the hoop structure to form anchoring bond, part of upward buoyancy borne by the concrete layer can be transmitted to the uplift pile, then the uplift pile and the ground wall are mutually anchored through the concrete layer, and the ground wall can bear the other part of upward buoyancy borne by the concrete layer; compared with the prior art, the anti-floating and anti-upheaval system has the advantage that the anti-floating and anti-upheaval performance of the concrete layer can be greatly improved.
本发明涉及一种深基坑抗拔桩锚固结构及其施工方法，所述锚固结构包括安装件、抱箍以及混凝土层；所述安装件包括固定套设于抗拔桩下端的套筒和应力扩散件，所述应力扩散件固定安装于所述套筒的上端；所述抱箍箍紧于所述套筒的外部，并与所述应力扩散件的底部抵贴；所述混凝土层是通过在所述基坑坑底浇筑混凝土。本发明通过抗拔桩与混凝土层通过套筒结构与抱箍结构的锚固措施，形成锚固握裹，可使得混凝土层承受的一部分上浮力传递至抗拔桩，再通过混凝土层与地墙互相锚固，地墙可承载混凝土层承受的另一部分上浮力，从而在深基坑内构成一个整体的抗浮、抗隆起体系，相较于现有技术，可大大提高混凝土层的抗浮、抗隆起性能。
