335 Resin Anchor Description
MSGLW series of longitudinal ribless threaded steel resin anchor metal rod products are widely used in underground rock, semi-coal rock and coal tunnel anchor support, especially suitable for underground tunnel and refuge support under complex conditions. The strength of the threaded section is greater than the strength of the rod body, and the threaded section has good bending and shear resistance.
The anchor has high strength, reasonable structure, large jacking force, can automatically adjust the direction of force, increase the binding force on the rock, and can be mechanized for quick installation. It can be used as end anchor, extension anchor and full anchor, mainly used for high strength support of large deformation roadway in highland pressure mines.

Product Details
Mining anchor is a kind of anchor commonly used in coal mine underground support and traditional metal anchor compared to the quality of its solid full-length equal strength length can be intercepted according to the specific needs of the rod easy to cut easy to operate and convenient so that you do not make difficult to use so that the roadway and other construction sites are very favorable to the safety and construction.
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 most basic part of the roadway support in contemporary coal mines, and it binds 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.
Installation and use
(1) Select the metal rod body and anchoring agent according to the design.
(2) Drill the holes on the anchoring substrate, and the diameter and depth of the holes should be matched with the specifications of the anchors.
(3) After drilling, use pressurized air or water to remove floating dust in the hole and load anchoring agent.
(4) the use of mixing equipment to drive the metal rod body, while stirring and advancing to the bottom of the hole, the mixing time should be less than the anchor solidifying agent gel time.
(5) Do not move the rod body during the waiting time.
(6)after the specified waiting time, can be on the tray spinning nut, bearing time reached, can test the tensile strength.
