Rigid-flexible composite uplift pile and mounting method thereof
The invention provides a rigid-flexible composite uplift pile. The rigid-flexible composite uplift pile comprises a plurality of uplift pile units, wherein each uplift pile unit comprises a rigid uplift pile and at least two rows of flexible piles; the rigid uplift pile is located in the center; the flexible piles are arranged around the rigid uplift piles; the rigid uplift piles and the flexiblepiles are mutually engaged, and the engagement size is 0.15-0.2m; the adjacent flexible piles are mutually engaged, and the engagement size is not smaller than 0.25m; and the uplift pile units are arranged in an annular or grid mode, and the distance between the rigid uplift piles of every two adjacent uplift pile units is not smaller than six times of the diameter of the rigid uplift piles. According to the rigid-flexible composite uplift pile, disturbance to easily-liquefied soil or soft soil is reduced during construction of the rigid piles, the side friction resistance of the rigid piles is greatly increased compared with the situation that the rigid piles make direct contact with the easily-liquefied soil or the soft soil, and meanwhile, the side friction resistance of the flexible piles is increased.
本发明提供了一种刚柔复合抗拔桩,包括多个抗拔桩单元,抗拔桩单元包括刚性抗拔桩和柔性桩,刚性抗拔桩数量为1个,且刚性抗拔桩位于中央;柔性桩数量为多个,且柔性桩环绕刚性抗拔桩设置;刚性抗拔桩和柔性桩之间相互咬合,咬合的尺寸为0.15‑0.2m;相邻的柔性桩之间相互咬合,咬合的尺寸为不小于0.25m,柔性桩至少有两排;抗拔桩单元以环形或格栅的形式排列,相邻的两个抗拔桩单元的刚性抗拔桩的间距不小于刚性抗拔桩直径的六倍。本发明不仅在刚性桩施工时减少了对易液化土体或者软土的扰动,还使刚性桩侧摩阻力比刚性桩与易液化土体或者软土直接接触处情况下大幅增加,同时还增大了柔性桩侧摩阻力。
