Threaded steel anchor is a commonly used geo-engineering support material, which is mainly characterized by good tensile strength and durability performance. Generally applicable to mine roadways, bridges and tunnels, rail slopes, 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 and other strength, compared with the same specification anchors 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. Rebar anchor is a very practical geological engineering support material, which has good tensile strength and corrosion resistance. When it is used, attention should be paid to the maintenance and upkeep in terms of safety, stability and durability to ensure its long-term and effective function.

Rebar anchors have high strength, reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can be mechanized for rapid installation. The whole length of the rod has rolled continuous threads with equal strength over the whole length; the fastening end is equipped with pre-stressing spacer and ball-shaped nut.

Rebar 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. Rebar anchors are divided into longitudinal ribless rebar resin anchors (referred to as left-handed anchors) and equal-strength rebar resin anchors (referred to as right-handed anchors). Left-hand and right-hand anchors implement the MT146.2-2011 standard, which is the basic component of tunnel support in contemporary coal mines, binding the surrounding rocks of the tunnel together, so that the surrounding rocks support themselves. Nowadays, anchors are not only used in mines, but also used in engineering technology to actively reinforce slopes, tunnels and dams. Anchor as a deep stratum of the tensile member, it is connected with the engineering structures at one end, the other end of the deep stratum, the whole anchor is divided into the free section and anchorage section, the free section is the anchor head of the tensile force to the anchor solid area, its function is to apply prestressing force to the anchor; anchorage section refers to the cement paste will be prestressing tendon bonded with the soil layer of the region, its function is to increase the friction effect of the anchorage solid bonded with the soil layer, increase the anchor solid pressure-bearing effect, will be the anchor of the soil layer, and will be the anchor of the soil layer, the anchor of the soil layer. Its function is to increase the bonding friction between the anchor solid and the soil layer, increase the pressure-bearing effect of the anchor solid, and transmit the tension of the free section to the depth of the soil.

1. In the design of rebar anchors, accurate calculation and comprehensive consideration are needed according to the actual engineering requirements and geological conditions.

2. In the production process of rebar 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. During the installation of rebar anchor, it should be operated in strict accordance with the installation drawings and technological requirements, to avoid improper installation, not tight connection and other problems.

4. During the use of rebar anchor, it should be inspected and maintained regularly, and problems should be dealt with in time to ensure its safety, stability and durability.
