Mine roadway underground support cable anchor bolts with rubber ring cable bolts is a pre-stressed anchoring technology used to reinforce rock and soil in mining, tunnel, slope and other engineering projects. It has the following advantages:
Improving anchoring force: Due to the effect of the expansion joint, the cage type anchor cable can fully mix and evenly mix the resin anchoring agent, firmly combine with the hole wall, and its anchoring force can be increased by 20% compared to ordinary mining anchor cables.
Keep centered and straight: Cage type anchor cables can keep the anchor cables centered and straight in the drilling hole, without tilting towards the hole wall, which helps to improve the anchoring force of the anchor cables.
Prevent end scattering: The end of the cage type anchor is fixed with a snap ring, which can prevent the end of the anchor from scattering and ensure the integrity and stability of the anchor.
Strong adaptability: Cage type anchor cables can be adjusted according to different geological conditions and engineering needs, making them more suitable for specific engineering environments.
Easy construction: The method of making cage type anchor cables is relatively simple. The steel strands can be twisted in the opposite direction through a dedicated cage splicer, causing them to break and disperse. Then, the filling material is filled, and the steel wires are twisted in the forward direction to form a cage shaped structure.
Widely used: Mine roadway underground support cable anchor bolts with rubber ring cable boltss are not only suitable for mining engineering, but also for other fields that require soil and rock reinforcement, such as tunnels, slopes, and other engineering projects.
In summary, cage type anchor cables have shown significant advantages in improving anchoring force, maintaining anchor cable centering, and preventing end dispersion through their unique structure and manufacturing method, making them an effective tool in geotechnical reinforcement engineering. When selecting anchor cables, appropriate anchor cable types should be selected based on specific engineering requirements and geological conditions to achieve the best reinforcement effect.
