1. Equal strength design of the whole rod body:
break through the mechanical bottleneck of traditional anchor rods.
1.1 Strength short board of traditional anchors
Ordinary rebar anchors have obvious mechanical defects:
The strength of rod body and threaded section is not consistent (usually 30%-50% difference)
Stress concentration leads to brittle fracture of threaded part
Ultimate load bearing capacity is limited by the weakest link
1.2 Technological innovation of equal-strength anchors
Adopting the whole rolling heat treatment process to realize:
√ The strength of the rod body and the threaded part are completely the same (HRB600 grade) √ Uniform force on the whole section, no weak link √ Tensile strength increased by 40% (actual strength increased by 40%). HRB600 grade)
√ Uniform force in the whole cross-section, no weak link
√ Tensile strength increased by more than 40% (measured ≥600MPa)
1.3 Engineering application value
Deep mine support: can withstand the ground pressure at a depth of more than 3,000m
Soft rock tunnel reinforcement: effectively inhibit the damage caused by large deformation
Dynamic pressure tunnel support: significant improvement in the performance of impact resistance
2. Excellent anti-corrosion performance:
the key guarantee to extend service life

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 against the anchor and start mixing (mixing time is specified according to the type of the anchoring agent), after mixing, unload the mixing tool, after reaching the waiting time, unload the mixing connecting head, put on the anchor plate, ball washer, friction washer, and tighten the nut with a wrench.
