The CHEERON combination anchor is composed of a rock anchor bolt body connected to the reinforcing bars through a connecting sleeve. Based on the common anchor rods, an extended design is made to solve the transportation and usage problems caused by overly long anchor rods in practical applications. This combined hollow anchor bolt is based on the advantages of hollow grouting anchor bolts, self-drilling hollow anchor bolts and expansion shell hollow anchor bolts, and can achieve good economic benefits and high construction efficiency in practical applications.

An anchor bolt composed of a hollow anchor bolt body, reinforcing bars, connecting sleeves, washers, nuts, stoppers, anchor heads, exhaust pipes, etc.
The connection between the connecting sleeve and the hollow anchor bolt body and the reinforcing bars adopts a straight thread mechanical connection, and a slurry outlet is provided on the connecting sleeve.
The rods can be cut on site and extended by connecting with sleeves. The length of the anchor rods can reach 20 meters or more.
CHEERON offers various types of anchor bolt sleeves (such as hollow grouting anchor bolts, self-drilling rock anchor bolts, expansion shell rock anchor bolts, etc.), and the connecting sleeves have the same designed tensile strength as the anchor bolt body.
Support for underground projects.
Reinforcement of unstable rock masses on slopes.
Overall reinforcement of soil mass.
