Mining Rock Bolts Let the manufacturer explain the difference between rock bolts and anchor cables

　　Mining rock bolt manufacturer: The difference between anchor cables and rock bolts

　　The difference between rock bolts and anchor cables is only a difference in quantity, not a difference in quality, but a difference in the tensile medium. The tensile part of the anchor cable uses steel wire strands, while the rock bolt uses high-strength hot-rolled threaded steel bars. It is usually used in large-tonnage anchoring projects. The tensile steel bars of the anchor cable use steel wire strands, and the rock bolt uses steel bars or steel pipes. Usually, when the anchor cable is subjected to force, it is subjected to force, and the stress form is divided into the anchoring section and the free section, which can be used as an anchoring project. It is a kind of anchor cable.

　　In China, generally, anchor cables need to be prestressed, so they are actively stressed and are mostly used in engineering parts that have already deformed or have strict deformation requirements. Rock bolts generally do not apply prestress (sometimes a little prestress is applied), so they are passively stressed, and the anchoring force is only exerted when the anchored rock and soil mass deforms. In addition, the length of the anchor cable is generally 20-50 meters, while the length of the rock bolt is within 20 meters. Internationally, anchor cables are just a type of rock bolt.

　　Mining rock bolt manufacturer: What problems are solved by the use of mining rock bolt anchors?

　　In recent years, with the continuous development of various industries, many products, including mining rock bolts and anchors, have been further developed and applied. Mining rock bolts and rock bolts are widely used in construction and engineering, which has greatly solved various technical and engineering problems and brought convenience to construction and engineering. The application and construction process of mining rock bolt anchors are very important and play a significant role in the completion of the task.

　　When anchoring with mining rock bolts, attention should be paid to the excavation, reinforcement, and slope construction, that is, excavation and protection are not allowed to be excavated to the bottom at once. According to the engineering elevation and design requirements of each work point, accurately measure the anchor hole position on the slope. The hole position error should not exceed 50mm. If the existing slope brushing is uneven or the site is particularly difficult, it needs to be agreed upon by the design and supervision unit. Under the premise of ensuring slope stability and structural safety, the positioning accuracy should be appropriately relaxed or the anchor hole position should be adjusted.

　　No matter what product is used, it is necessary to master the relevant knowledge first. The basic knowledge of mining rock bolt anchoring clamps and connectors is introduced as follows:

　　1. The anchors and connectors of mining rock bolts are core components in prestressed engineering. They are the key to ensuring that the strength of the prestressed tendons is fully exerted and the prestressed tensioning is smoothly achieved. They should have reliable anchoring performance, sufficient load-bearing capacity, and good applicability.

　　2. Prestressed tensioning anchoring system, according to the type of prestress, includes steel wire strand bunch upsetting anchoring system, steel wire strand clamping plate anchoring system, and hot-rolled threaded steel bar anchoring system; according to the anchoring principle, there are support anchoring, wedging anchoring, clamping anchoring, and combined anchoring systems. Threaded end steel bar anchors, hot-rolled threaded steel bar anchors, and upsetting anchors belong to support anchors.
