Embodiment 1
[0030] This embodiment provides a treatment method for concrete holes or exposed bars, the steps comprising:
[0031] S1 Chisel removal of unqualified concrete: Chisel away uncompacted loose concrete and floating stones, check that the surface of the concrete after chiseling is dense and there are no obvious gaps;
[0032] S2 interface cleaning: use high-pressure air to clean the residue in the tank and rinse it with high-pressure water;
[0033] S3 mold support: choose plastic formwork for mold support;
[0034] S4 Stirring: Pour the concrete repair material into the mixing container, add water until the diffusion degree is 450-600mm, and stir evenly;
[0035] S5 pouring of concrete repair material: pouring the concrete repair material obtained in step S4, and vibrating and compacting;
[0036] S6 maintenance: After initial setting, cover with plastic film for moisturizing and curing for 3 hours;
[0037] S7 formwork removal: remove the formwork after maintenance;
[0038...
