Project overview: Longkou Liangshan Coal Mine rescue renovation project aim to increase the load, improve the structural strength
Reinforcement method: pasting carbon fiber cloth reinforcement, rebar planting reinforcement, bonding steel reinforcement
Material selection: carbon fiber fabric, carbon fiber impregnating adhesive, anchoring epoxy resin adhesive, steel bonding adhesive
Construction technology: reinforcing by pasting carbon fiber cloth: surface treatment → base adhesive construction → leveling construction → rolling → pasting cloth → secondary rolling → curing and maintaining
Reinforcement: drilling → cleaning → injection → screwing into steel bar→ curing
