Abstract

The invention discloses an anchoring system for slope supporting. The anchoring system comprises anchoring piles and at least one lattice beam arranged in the transverse direction of a slope. The at least one anchoring pile is arranged in the longitudinal direction of the lattice beams. Each anchoring pile comprises an anchoring pipe, an internal core rod which is arranged in the anchoring pipe and can move axially and at least one retaining assembly which is arranged on the anchoring pipe and matched with the internal core rod for retaining. Ejection blocks are pushed by axial movement of the internal core rods to move in the radial direction of the anchoring pipes. The free ends of retaining rods can be pushed by the ejection blocks to swing, and therefore the retaining rods are expanded towards the outer sides of the anchoring pipes, the anchoring piles are overall and firmly fastened in slope rock soil, and overall outward retreating of the anchoring piles can be avoided. Extrusion push is carried out in the manner that the internal core rods cooperate with the conical faces of the ejection blocks, and therefore the contact area is large, the overall supporting effect generated after pushing is good, and the retaining rods are prevented from moving to the inner side after swinging outwards; and the strength of the anchoring pipes can be enhanced through the internal core rods, and therefore the overall bending resisting capacity and shear resisting capacity of the anchoring piles are improved, and high anchoring force is achieved.

Description
