The mechanism of bolt support includes arch reinforcement, suspension, composite beam, surrounding rock reinforcement and span reduction.
Bolt support is a kind of reinforcement and support method used in surface engineering such as slope, rock and soil deep foundation pit and underground cavity construction such as tunnel and stope. Rod columns made of metal pieces, wood pieces, polymer pieces or other materials are driven into pre-drilled holes in the surface rock mass or the rock mass around the chamber, and the hanging effect, composite beam effect and reinforcement effect are produced by combining the surrounding rock with the stable rock mass by using the special structure of the head and the rod body and the tail supporting plate (or not), or relying on the bonding effect, so as to achieve the purpose of supporting.
It has the advantages of low cost, good supporting effect, simple operation, flexible use and less construction clearance.
