Hollow grouting rock bolts are mostly used in relatively stable and complete rock formations. Resin, engineering glue, quick-setting cement and other anchoring agents are injected from the center of the anchor, which is better than ordinary anchors. Although hollow grouting rock bolts have been widely used in road engineering, but for various reasons, many people do not know how to buy hollow grouting rock bolts? Generally speaking, if the quality of the hollow grouting rock bolts purchased is not good, it will affect the overall support effect. So, how to choose a suitable hollow grouting rock bolt?

Generally speaking, the core part of the hollow grouting rock bolt should be the reinforcement of the support of the loose layer. It must reach a certain mechanical performance and meet all the coupling conditions on the anchor system before it can be used well, so when purchasing hollow grouting rock bolts, we must pay attention to its yield strength, pressure resistance and elongation, and also pay attention to whether the nuts and connectors are strong.

In addition, when buying hollow grouting rock bolt, you should also pay attention to whether its inner hole meets your own needs. Because the grouting pipe must have a large enough inner hole to allow the grouting liquid to fill the anchor hole smoothly, so choose the product at that time, we must pay attention to whether its inner hole meets our own needs. If it is not possible, we can customize it to the manufacturer directly, so that the product produced is more suitable, and the overall support effect will be better!
