The difference between grouting anchor cable and ordinary anchor cable is that grouting anchor cable is to inject high-strength cement slurry into the bolt hole, so that the bolt is closely combined with the surrounding soil, so as to achieve the purpose of strengthening the soil body.

The ordinary anchor cable is to fix materials such as steel strands or steel bars in rock or concrete through anchors to play a role in reinforcement.

The advantages of grouting anchor cables are:

(1) Grouting anchor cable can improve the tensile strength of the bolt;

(2) Grouting anchor cable can improve the adhesion between the bolt and the surrounding soil;

(3) Grouting anchor cable can improve the anti-corrosion performance of the bolt;

(4) Grouting anchor cable can improve the service life of the bolt
