Sharp End Threadbar Bolt Support
Sharp End Threadbar Bolt Support Functions
The Sharp end threadbar bolt support is a kind of reinforcement support method used in surface engineering such as coal mine,slop deep foundaition pit of rock and soil and underground chamber construction such as tunnel and stope.Ploe into the surface of the rock mass or cavern surrounding rock mass in the drilled holes in advance,to use its head,the special structure of the rod body and tail plate blend and stability of rock mass surrounding rock and suspension effect,effect of composite beams,reinforcement effect,in order to zchieve the purpose of supporting.
