Research on Construction Technology of Guide-Hole Implantable Branch-Provided Rock Anchor Rod Based on Experimental Analysis

In order to overcome the defects of the anchor rod as insufficient anti-pull force, low elongation, low stability during construction and difficulty for drilling the rock stratum to be anchored, this paper innovates on the conventional anchor rod by introducing the newly-developed construction technology of guide-hole implantable branch-provided rock anchor rods, and presents its technology principles, the application scope, the technological characteristics, the construction process and the operating points. The construction technology improves the anchoring force of the anchor rod per unit length, overcomes the problem of insufficient anti-pull force, relatively reduces the anchor rod and the rock stratum drilling depth, facilitates the drilling and anchoring construction, and achieves excellent economic benefits and has wide popularization value.
