The main function of the mine right-handed rock bolt is to restrain and strengthen the soil, it can not only make up for the lack of tensile and shear resistance of the soil, and during the grouting construction, the cement slurry can penetrate into the cracks inside the rock and soil. Through the reinforcement effect of cement slurry on the rock and soil body, the structural strength of the rock and soil body is further enhanced. The hanging steel mesh erupted concrete surface layer can connect a single right-handed rock bolt and an anchor plate to form an anchor rod group, so that the rock bolt and the soil body are connected into a whole tightly.

At the same time, the erupted concrete can close the slope and prevent the slope from being washed by water. The right-handed rock bolt passes through the weak, loose and unstable rock and soil body and is anchored on the deep and stable rock and soil body to provide sufficient pulling force to overcome the self-weight and sliding force of the falling rock and soil body and avoid the cave wall sliding.

Notes on installing right-handed rock bolt:

1. Before installing the anchoring medicine roll, first insert the rock bolt into the hole to probe the depth of the bolt eye, and check whether the hole depth meets the requirements. If the depth is not enough, you should drill the head to reach the requirement.

2. When installing, first put the anchoring medicine roll into the eye in a regular amount (using 2 medicine rolls), and then insert the rock bolt. At this moment, install the joint sleeve, insert the wind anchor, start the wind anchor to rotate it, and gradually advance to the bottom of the eye. After 20s of mixing, stop drilling and unload the inferior anchor. Wait 5 minutes before the joint sleeve can be removed. After 20 minutes, put on the pallet and tighten the nut with a wrench.

3. The anchor plate should be close to the rock wall. If the rock wall is uneven, first level it with a hand pick, and then install the right-handed rock bolt.

In daily use, we must grasp the installation method correctly and precautions of the right-handed rock bolt to make it better play the supporting effect. If you have any support needs, please contact us!
