Maintaining method for basement exterior wall
The invention relates to a maintaining method for a basement exterior wall. The maintaining method comprises the steps that an exterior wall reinforcing steel bar is strapped on a basement baseboard structure, and an exterior wall formwork is supported and arranged; concrete is poured into the exterior wall formwork to form an exterior wall structure; surface temperature of the exterior wall structure is controlled in the hydration warming process of the exterior wall structure, therefore, a constant temperature concrete layer with a certain thickness is formed in the surface of the exterior wall structure, and the temperature rising value of the constant temperature concrete layer is smaller than or equal to a set value in the whole pouring process; in the temperature-falling process of the constant temperature concrete layer, pulling stress is generated by the concrete inside the constant temperature concrete layer, pressure stress equal to the pulling stress is generated by the constant temperature concrete layer correspondingly, and therefore the exterior wall structure is controlled not to generate cracks. The constant temperature concrete layer is formed in the surface of the exterior wall structure, temperature shrink inside the constant temperature concrete layer is restricted, reasons for generating of the cracks of the exterior wall structure are controlled, and the cracking problem of the exterior wall structure is solved.
