Applicable conditions for threaded anchor rods:
l、 Determine the anchor bolt hole position according to the design requirements, and use a chisel, anchor bolt drilling machine, or coal-fired drill to drill holes with a depth 80-100mm shorter than the length of the anchor bolt.
2. Insert a compressed air duct into the fundus of the eye and blow away the rock powder inside the hole through compressed air.
3. The drilling diameter is required to be 6-12mm larger than the anchor rod diameter.
4. Use anchor rods to feed the medicine roll into the fundus, start the stirring device for stirring, and strictly control the stirring time according to the requirements of resin anchor fixative.
5. After reaching the curing time, put on the tray and tighten the nut.
