Right Handed Rock Bolt For Sale

Rock Bolts are generally suitable for reinforcement of mine roadways, bridge tunnels, track slopes, etc. The general rock bolt holes are drilled with a bolt drill, then the appropriate anchoring agent (resin roll) is placed, and then anchor drill is used. The tool is used to drill anchor rod into anchor hole to anchor, and then use tool such as the bolt rig to install nut.

Right-handed anchor, full name of strong-threaded steel resin rock bolt is right (or left) Manufactured by refining and rolling rebar, which is featured with continuous thread and nut can be used for the whole length. Used in conjunction with anchor plate nut and roadway support. The rock bolt is a replacement product of anti-twist anchor and has superior performance.

Right-hand Rock Bolt Technology Details

Rock bolts are classified according its diameter. Generally, most commonly used ones are: 16mm, 18mm, 20mm, 22mm. Achor rod body can achieve best matching with the anchor hole diameter and the diameter of the resin medicine, and has strong anchoring force, high elongation and safety. Reliable, high quality, low consumption, easy to use and so on.

Slope Anchor - Right Handed Rock Bolt

Bolt material description: high-strength rock bolt material adopts elongation of not less than 15%, yield strength of not less than 335MPa, breaking strength of not less than 490MPa, and material of 20MnSi is heat-sealed, and compressive pressure is 20 tons. To 50 tons, straightness tolerance of anchor rock bolt is Φ18 to Φ22 is ≤2mm/m, and linear tolerance of anchor rod of Φ16 is less than 4mm/m. The load capacity of rod tail should be not less than 75% of base metal breaking force. 

Use Rock Bolts to Increase Dam Stability

Grouted rock bolts are installed in the interface between rock mass and concrete in concrete dam structures as an additional safety measure. They can theoretically contribute to increase both the stability against sliding as well as overturning. One can however realize that they cannot increase the bearing capacity of the dam foundation since the rock bolts are inactivate as long as they are not exposed to tensile stresses.
