Intelligent curing device and method for ultra-high performance concrete

The invention relates to an intelligent curing device and method for ultra-high performance concrete. The intelligent curing device comprises a movable child-mother pouring jacket, a hollow mechanical arm, a temperature and humidity collaborative curing template and a temperature and humidity sensor. A rotating support is arranged at the top of the outer mother box, and a control module is arranged on a box body; a water storage tank, a pump and a motor are arranged in the inner sub-box in a matched mode, a through hole coaxial with the rotating support is formed in the top of the inner sub-box, the two ends of the hollow mechanical arm are connected with the temperature and humidity collaborative maintenance formwork and the rotating support respectively, and a power transmission line and a water conveying pipeline are arranged in the hollow mechanical arm. The shape of the temperature and humidity synergistic curing template is consistent with the forming shape of a cured UHPC material, spray heads and grat
