With the development of technology,the utilization of hollow anchor bar has became more and more popular,it can not only be used in mining,tunneling,foundation support project,hydroelectric but also applied in transportation and some other reinforcement work.

Hollow bar anchor is a kind of necessary structure to pass tension into stable rock mass,when steel strand or high stress steel bundle can be involved as the material of rod body,anchor bar will be also defined as anchor cable.

Self-drilling anchor bar is generally installed into the boreholes and it's also a kind of debar that one end was extended into hard soils,in addition,the tensiled rock bolt can be combined with full length grout to guarantee the stability and provide high bonding stress between soils and rock anchor.

Besides,the other end of hollow anchor was connected with construction structure to exert prestress to bear tension that come from soil pressure,water pressure or wind pressure and so on,which has been suggested as a valid approach to maintain buildings and civil constructions.

Ground Improvement techniques are used to stabilize, strengthen, consolidate, create imperviousness & increasing the bearing capacity of the existing grounds. 

Sinorock has focused on studying the technology of self drilling hollow anchor bar  system for ground improvement.Our self drilling anchors are manufactured with advanced production equipment and technologies, and raw materials are thoroughly inspected to ensure high quality. Then these products have reliable quality and reasonable price.
