equal strength threaded anchor *., *, *. equal strength threaded anchor, left-hand and right-hand anchor anchor are contemporary coal mine Among them, the most basic component of tunnel support is that it binds the surrounding rock of the tunnel together so that the surrounding rock itself supports itself. Nowadays, anchor bolts are not only used in mines, but also in engineering technology, for slopes, tunnels, The dam body is actively reinforced.
The anchor rod is a tensile member that goes deep into the ground. One end of it is connected to the engineering structure, and the other end goes deep into the ground. The entire anchor rod is divided into a free section and an anchored section. The free section refers to the tensile force at the anchor head. Passed to the anchor area, its function is to apply prestressed anchorage to the anchor rod. When the anchor section refers to the area where the cement slurry bonds the prestressed tendons to the soil layer, its function is to increase the bonding friction between the anchor and the soil layer. , increase the pressure-bearing effect of the anchor, and transmit the tension of the free section to the depth of the soil.
The performance of the fully threaded anchor bolt for mining has reached the international advanced level. It has a reasonable structure and the strength of the entire thread length of the anchor bolt. Compared with the anchor bolts of the same specification, the load-bearing capacity is improved and the scope of use of the anchor bolt is expanded. It can realize end-end Anchors, extended anchors and full anchors have the advantages of easy operation and low price, and are widely used in various types of tunnel support in coal mines, railways, hydropower and other projects.
Mine support material products mainly include: jointed pipe anchors, resin anchors, metal mesh sheets, equal-strength threaded steel resin anchor metal rod bodies, non-longitudinal rib threaded steel resin anchor metal rod bodies, anchors Rod pallets and coal mining equipment and accessories.
