Product Details

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 component of tunnel support in contemporary coal mines, binding the surrounding rocks of the tunnel 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.
