Abstract

The bamboo anchor rod assembly comprises a bamboo anchor rod and an FRP reinforcing layer, the FRP reinforcing layer comprises a base body and a fiber structure arranged on the base body, the FRP reinforcing layer is arranged on the bamboo anchor rod, and the FRP reinforcing layer is connected to the bamboo anchor rod through a bonding layer. According to the bamboo anchor rod assembly reinforced by the FRP, the FRP reinforcing layer is arranged on the bamboo anchor rod, so that the structural strength of the bamboo anchor rod assembly can be improved, the corrosion resistance of the bamboo anchor rod assembly is enhanced, expansion of cracks in the bamboo anchor rod is effectively inhibited, the durability of the bamboo anchor rod assembly is improved, and the service life of the bamboo anchor rod assembly is prolonged. Therefore, the bearing capacity of the bamboo anchor rod can be effectively improved, and the service life of the bamboo anchor rod is prolonged.

Description

technical field [0001] The invention relates to the field of anchor rods, in particular to a bamboo anchor rod assembly reinforced with FRP. Background technique [0002] Bolt support refers to a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chambers such as tunnels and stopes. The rod column is made of metal parts, wood parts, polymer parts or other materials, and is driven into the pre-drilled holes in the surface rock mass or the rock mass around the chamber. optional), or rely on the bonding effect to combine the surrounding rock and the stable rock mass to produce suspension effects, composite beam effects, and reinforcement effects, so as to achieve the purpose of support. [0003] Based on the concept of green environmental protection, the development of green building materials is the general trend. As a fast-growing natural fiber material, bamboo has the ecological advantages of being r...
