Composite rotary pile anchor
The invention discloses a composite rotary pile anchor. The composite rotary pile anchor comprises an anchor rod, a spiral blade and a soil retaining assembly. The soil retaining assembly is installed on the upper portion of the anchor rod. When soil burying operation is carried out, the anchor rod enables the spiral blade and the soil retaining assembly to be inserted into the ground through spiral rotation, and then the soil retaining force is improved through contact between the soil retaining assembly and soil. The rotary pile anchor has the beneficial effects that on the basis that the structure and the function of an existing rotary pile anchor are not changed, the soil retaining area of the rotary pile anchor is effectively increased by additionally arranging the soil retaining assembly which can be inserted in a spinning mode along with the anchor rod, and then the soil retaining force of the rotary pile anchor is improved. The mechanical properties of pulling resistance and soil retaining force are consistent, the operation range of the rotary pile anchor is expanded, the operation capacity of the rotary pile anchor is improved, and the operation safety is guaranteed.
本申请公开了一种复合型旋转桩锚，包括锚杆、螺旋叶片以及挡土组件；挡土组件安装于锚杆的上部；当进行埋土作业时，锚杆通过螺旋转动将螺旋叶片以及挡土组件插入地面，进而通过挡土组件与土壤的接触以提高挡土力。本申请的有益效果：本申请在不改变现有旋转桩锚的结构和功能的基础上，通过加装可以随锚杆进行自旋插入的挡土组件，有效的增大旋转桩锚的挡土面积，进而提高旋转桩锚的挡土力。使得其抗拔力和挡土力的力学性质一致，拓展了旋转桩锚的作业范围，提高其作业能力，保证了作业安全性。
