Brief introduction of self drilling anchor bar

Self drilling anchor bar has drilling, injection, anchor functional integration, it is an advanced anchoring system, solved the problem of hole collapse of greenhouse construction, can ensure the grouting effect under the complex geological conditions.In bending, shear strength and surface bonding interface is obviously better than the same conventional mortar anchor rod, it can be arbitrarily cut, connections, prestress and load release, and can be used as grouting pipe, there are no special requirements for the required machines and equipment, material.the process is simple and has great application value. Self drilling anchor bar is made of the rod (full thread rod), connected sets, disposable drill, arched plate and nut components. Bolts tail can be added rubber seal slurry grouting stopper.
