Sinorock hollow bar is practical,economical for you
With the rapid development of mining,tuneling,the geological conditions are becoming more and more complex and more and more difficulities began to appear in roadway support projects.Under soft,high-stressed rock conditions,it's hard for the installation of anchor plate,so it'apparently that the support projecte can be destructed and ruined by the lack of strength of anchor plate.As a result,these problems have been disturbing operators for a long term.
Self drilling hollow bar is versatile in tuneling,slope stabilization,foundation support,dike reinforcement,arch reinforcement and tunneling support projects.Confined by the construction environment,it has not been applied in roadway support project.There are a great many successful cases in the intsllation of the self drilling hollow bar that we can learn from.With the involvment of self drilling hollow bar,the construction will become more easier,practicle and economical and therefore it plays a vital role in stablizing the deformation of rock and providing more reinforcement for roadway support.
The self drilling hollow bar is combined by four parts include drill bit,anchor bar,fasten units and accessories.The drill bit can be used to drill and anchor,while the anchor bolt features drilling,anchoring and grouting for a single operation.And the fasten equipment can offer a strong stability and reinforcement in support projects.
