Composite uplift pile with negative Poisson's ratio structure
The invention belongs to the field of building uplift piles, and particularly relates to a negative Poisson's ratio structure composite uplift pile which comprises an outer sleeve with a negative Poisson's ratio effect, a flexible lining pipe attached to the inner wall of the outer sleeve and a concrete pile body arranged in the flexible lining pipe. A cylinder body of the outer sleeve is provided with holes which are periodically alternated horizontally and vertically, a reinforcement cage is arranged in the concrete pile body and comprises a plurality of main reinforcements which extend in the length direction of the concrete pile body and are annularly arranged, and spiral stirrups extending in the length direction of the concrete pile body are jointly arranged on the outer sides of all the main reinforcements. A plurality of annular stiffening ribs are arranged on the inner sides of all the main ribs in the length direction of the concrete pile body, and a gap is formed between every two adjacent annular stiffening ribs.
本发明属于建筑抗拔桩领域，具体的是一种负泊松比结构复合抗拔桩，包括具有负泊松比效应的外部套筒，贴设于外部套筒内壁的柔性内衬管，以及设置于柔性内衬管内部的混凝土桩体；所述外部套筒的筒体具有周期性横竖交替的孔洞，所述混凝土桩体内部设置有钢筋笼，所述钢筋笼包括多个沿混凝土桩体长度方向延伸且呈环状排布设置的主筋，所有的主筋外侧共同设置有沿混凝土桩体长度方向延伸的螺旋箍筋，所有的主筋内侧沿混凝土桩体长度方向设置有多个环形加劲筋，相邻环形加劲筋之间具有间距。
