This product is specially developed for large diameter Steel Wire Inside Grouting Anchor Cable in coal mine. Suitable for drilling hole diameter Φ70-80mm. The fast inorganic anchorage material can be used to end the anchor, and the highpressure grouting after prestressing is applied to make the slurry fully diffuse in the floor strata and improve the effect of strengthening the floor.
Main technical features
1. The cage structure (3) at the front end of the anchor cable is conducive to improving the bonding and anchoring effect with inorganic materials;
2. The cable body is processed with high-strength spiral rib steel wire to increase the load transfer effect of the anchor cable;
3, the use of hole sealing process, tensile pretension on the tray with concrete leveling, improve the sealing effect;
4. The cage shape of the tail and the sealing structure of the upper part ensure that the anchor cable body is centered;
5. The grouting hole is located at 1.3m from the tail of the cable body to ensure the grouting effect;
6. High pressure grouting pump can be used to expand the diffusion radius of the slurry.
As an important structural material, anchor cable has a number of significant advantages:
High strength and excellent tensile performance: the anchor cable can withstand huge tension, and its main design purpose is to withstand tension. This strong tensile performance makes the anchor cable perform well in a variety of occasions that need to withstand tension, such as construction, Marine and Marine engineering fields.
Strong durability: The anchor cable is usually made of high-strength steel wire or steel strand, which is not only strong, but also has good durability and fatigue resistance. Therefore, the cable has a long service life and can maintain stable performance in various environments.
