Mai-self-anchor drilling, injection, anchor integration features, an advanced anchorage system to solve hole collapse in the the bassoon shed construction issues, to ensure that the the grouting effect under complicated geological conditions. Significantly better than the same cross-section of conventional mortar anchor, flexural, shear strength and surface bonding can be cut, connect, prestressed and load release, and can be used for grouting pipe, machinery equipment required materials no special requirements, the process is simple, has great value.
Mai-self-anchor rod (air threaded rod), connected sets, disposable drill, arched plate and nut. Grouting bolt tail rubber seal slurry additional plugs. Drilling bolt tail by connecting sets of additional solder tail (Shank shape and drill pipe).
