Figure 1 As shown, it includes two cast-in-place support columns 1 and a staircase 2. The two cast-in-place support columns 1 are exposed to the elements for extended periods. Under conditions of prolonged exposure to rain, cold winds, and direct sunlight, cracks, peeling, and exposed rebar may appear on the outer surface of the cast-in-place support columns 1. This necessitates reinforcement and repair of the cast-in-place support columns 1. However, existing reinforcement and repair methods have the following drawbacks:
