Reinforced screw anchor-rock anchor rod composite pile connecting method
The invention discloses a reinforced screw anchor-rock anchor rod composite pile connecting method which comprises the following steps: roughening the inner wall of a screw anchor, and arranging a steel wire mesh on the inner wall of the screw anchor; and a cementing material is poured into the spiral anchor and the rock anchor rod, and connection of the spiral anchor-rock anchor rod composite pile is achieved. According to the method, the connecting strength on the contact surface can meet the design requirement, and the situation that the whole foundation loses efficacy and loses the bearing capacity due to the fact that the connecting position is damaged when the spiral anchor-rock anchor rod composite pile foundation is in the normal service state is avoided.
本发明公开了一种增强螺旋锚‑岩石锚杆复合桩连接方法，对螺旋锚的内壁进行打毛处理，然后在螺旋锚的内壁设置钢丝网；向螺旋锚和岩石锚杆浇筑胶结材料，实现螺旋锚‑岩石锚杆复合桩连接。本发明可使接触面上的连接强度达到设计需求，螺旋锚‑岩石锚杆复合桩基础在正常服役状态下不发生由于连接处破坏，导致的基础整体失效，丧失承载能力。
