Most Popular Galvanized Steel Wire Rope
The advantages mainly include the following points:
1. Adopting reverse grouting method, the process is simple and efficient, so that the slurry fully fills the borehole, and at the same time meets the requirements of high-pressure grouting, realizes the combination of anchor injection, avoids repetitive construction, and improves the construction efficiency.
2. Integrating the functions of ordinary anchor cable and grouting together, the strength of the new rock body can be increased by about 40% through anchor injection and cementing of surrounding rock, effectively realizing active support and self-control of surrounding rock.
3. The steel strand is processed with prestressed spiral ribs. Compared with ordinary glossy steel strand, the fabricated anchorage force of prestressed spiral ribbed steel wire anchor cable is greatly increased, which enhances the cementation effect and stability and improves the safety and reliability of the project.
Product Details:
Mining anchor cable is used in coal mines or other mines, shafts, perimeter rock plus circle, is composed of stranded wire, anchoring agent, tray, anchorage and other anchoring accessories, can be mechanically tensioned, the perimeter rock to exert active pressure of a device. Mining anchor cable structure generally consists of amplitude anchor head, anchor cable body and outer anchor head three parts together. Inner anchor head is also called Anchor section or anchor root, is anchored in the rock body to provide prestressing root, according to its structural form is divided into two categories of mechanical and cemented, cemented is divided into two categories of mortar cemented and resin cemented, mortar is divided into the second grouting and a grouting type. External anchor head, also known as external anchorage section, is the anchor cable to provide tension tonnage and locking parts, the types of anchor plug type, threaded, reinforced concrete cylinder anchor pier type, pier head anchor type and steel frame type. As the length of the steel hinged wire is not restricted, the anchor circle section can be anchored in the hard top plate, at the same time, because of the steel hinged wire strength level is higher, can provide a larger prestressing force, so that the anchor group section of the lower part of the composite roof joint one, forming a unified rigid roof, play a better support effect.

The structural features mainly include the following:
1. drilling through weak rock formations or sliding surfaces: the product is drilled through weak rock formations or sliding surfaces to provide access and support for subsequent consolidation and anchoring.
2. One end is anchored in a hard rock formation: One end of the product is secured in a hard rock formation, ensuring the reliability and stability of the anchoring.
3. The other free end is tensioned: the other free end of the product is subjected to a tensioning operation, which exerts pressure on the rock formation by applying tension in order to increase the support and stability of the rock.
4. For anchoring unstable rock: the product is designed to be used for anchoring unstable rock to enhance the fixity and stability of the rock layer by applying pressure and tension, so as to improve the safety of the project.
Taking the above structural features into consideration, it can be seen that this product is suitable for the field of geotechnical engineering, and can effectively anchor and support unstable rock bodies to ensure the stability and safety of the project.
Usage:
1. Drilling preparation: according to the diameter and length of the anchor cable, drill a suitable hole and remove debris in the hole.
2. Injection of resin anchoring agent: according to the design requirements, select the appropriate type and quantity of resin anchoring agent and inject it into the hole.
3. Steel cable fixing: Use the anchor cable to push the resin anchoring agent to the bottom of the hole, and connect the tail of the anchor cable with the anchor drilling rig connector.
4. Resin mixing: Start the anchor drilling rig and mix the resin anchoring agent according to the specified mixing time.
5. Curing process: Wait for the resin anchoring agent to solidify and then install the pallets and anchors.
6. Tensioning: Use the tensioner to pull the anchor cable to the predetermined pre-tensioning force.
