Best Quality Round Bar Supplier

Description of left-handed non-longitudinal ribbed rebar anchors

Left-handed anchor rods, for roadway support, are characterized by high strength, reasonable structure and large preload force. Left-handed anchor can increase the binding force on surrounding rock, and the installation is mechanized, which is easier and faster. Lefty anchors can be end anchors, extension anchors and full anchors. According to the steel grade, the left-hand anchor is classified as MG335/MG500/MG600, and the diameter of the rod body is from 16mm to 22mm, which can also be processed according to the construction requirements. Left-hand threaded steel anchor without longitudinal ribs has 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 quick installation. Can be end anchor, extension anchor and full anchor, mainly used for high pressure mines with large deformation of the high strength of the roadway support, but also can be used for railroads, hydropower and other types of projects of high strength roadway support, mining anchor is a commonly used in coal mines under the support of the anchor and the traditional metal anchor compared to the quality of the anchor it is solid full-length length of the length of the strong can be according to the specific needs of the intercepted rod easy to cut easy to use and convenient operation allows you to use up to not be a problem so that the safety and safety of construction sites such as roadways and so on. Roadway and other construction sites are very favorable to the safety and construction.

Product Description:

Left-handed anchor rods, for roadway support, are characterized by high strength, reasonable structure and large preload force. Left-handed anchor can increase the binding force on the surrounding rock, and the installation is mechanized, which is easier and faster. Lefty anchors can be end anchors, extension anchors and full anchors. According to the steel grade, the left-hand anchor is classified as MG335/MG500/MG600, and the diameter of the rod body is from 16mm to 22mm, which can also be processed according to the construction requirements.  Left-hand and right-hand anchors implement the MT146.2-2011 standard, which is the most basic component of tunnel support in contemporary coal mines, binding the surrounding rocks of the roadway together, so that the surrounding rocks support themselves. Nowadays, anchor rods 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.

Anchor use method.

1. Determine the anchor hole position according to the design requirements, and drill the hole with drilling rig.

2.Blow out the rock dust in the hole with pressurized air.

3. Send the anchoring agent to the bottom of the hole, hold it with the anchor rod and start mixing (mixing time is specified according to the type of anchoring agent), after mixing, unload the mixing tool, after reaching the waiting time, unload the mixing connecting head, install the anchor plate, ball washer, friction washer, and tighten the nut with a special wrench.
