Matters needing attention in the construction process of planting reinforcement:
 
(1) The drilling position, size and depth shall be marked according to the design requirements.
 
(2) After drilling, the dust in the hole shall be blown out by air compressor or other equipment. After the hole is cleaned, the hole shall be blocked with cotton wire to avoid dust falling into the hole.
 
(3) The rust and oil stain in the anchorage range of steel should be removed, and the bolts should also be derusted.
 
(4) According to the formula, before preparing the planting glue, components a and B should be mixed evenly, and then the glue should be mixed according to the mass ratio of main agent: curing agent = 2:1, and the mixture should be evenly stirred with an agitator. When mixing, try to mix along the same direction to avoid air entering and forming bubbles.
 
(5) Pay attention to the amount of glue, ready to use, if not used up, should be re sealed storage.
 
(6) During glue injection
 
a. Keep low pressure and low speed glue injection, start from one end, close the current glue injection nozzle when there is glue liquid flowing out from the adjacent glue injection nozzle, and move to the glue injection nozzle to continue the glue injection.
 
b. Make sure the hole is full of glue.
 
c. Prevent the adhesive layer from hollowing out.
 
(7) After the completion of anchoring, temporary fixation shall be done. No artificial agitation is allowed during the curing period, and special personnel shall be assigned to take care of it when necessary.
