Advantages of right-hand anchor.
Anchor high strength, reasonable structure, anchor full thread full length equal strength, solved the anti-twist anchor thread and pat flat at the low strength of the shortcomings; than the same specifications of the anti-twist anchor bearing capacity increased by 40%; easy to operate, inexpensive, able to automatically adjust the direction of the force to increase the binding force on the surrounding rock, can realize the rapid installation of the mechanization, can be the end of the anchor, lengthening anchors and the whole anchor, mainly used for high ground pressure mines with large deformation of the roadway It is mainly used for high strength support of large deformation roadway in high pressure mines, and is widely used in coal mines, railroads, hydropower and other projects for all kinds of roadway support.
Description.
Right-hand anchor is a very practical geo-engineering support material, which has good tensile strength and corrosion resistance. When it is used, attention should be paid to the maintenance and care in terms of safety, stability and durability to ensure its long-term and effective function. Generally applicable to mine roadways, bridge tunnels, track berms, etc. to strengthen the support, the general anchor hole is to use the anchor drilling rig to drill holes, and then put the appropriate anchoring agent (resin medicine roll), and then use the anchor drilling rig and other tools to drill the anchor into the anchor hole to the anchoring agent for stirring anchor, and then use the anchor drilling rig and other tools for nut installation; anchor full thread full-length equal strength, compared with the same specifications anchor Load carrying capacity increased by 40%; expand the scope of anchor use, can realize the end anchor, lengthening anchor and full anchor; easy to operate, low price and other advantages, widely used in coal mines, railroads, hydropower and other projects of various types of roadway support.

Anchor Technical Characteristics
Anchor according to the diameter to be classified, generally the most commonly used are: 16mm, 18mm, 20mm, 22mm; anchor rod body can be realized with the anchor hole diameter, resin maki diameter better match, with strong anchor force, high elongation, safe and reliable, high quality and low consumption, easy to use and so on.
Anchor material description: high strength anchor raw materials used in the elongation of not less than 15%, yield strength of not less than 335MPa, breaking strength of not less than 490MPa, the material for the 20MnSi steel by hot lashing and become, respectively, compressive 20 tons to 50 tons, Φ18 to Φ22 rod straightness tolerance ≤ 2mm / m, Φ16 rod straightness tolerance is less than 4mm / m. Rod tail The bearing capacity of the screw thread should be not less than 75% of the breaking force of the parent material of the rod.
Product Construction Points.
1. In the design of right-hand anchor, accurate calculation and comprehensive consideration are needed according to the actual engineering requirements and geological conditions.
2. In the production process of anchor, it is necessary to select, process and manufacture the materials in strict accordance with the design requirements to ensure its quality and performance.
3. In the process of anchor installation, it is necessary to operate in strict accordance with the installation drawings and technological requirements, to avoid improper installation, connection is not tight and other problems.
4. During the use of anchor, it should be inspected and maintained regularly, and problems should be dealt with in time to ensure its safety, stability and durability.
