The invention discloses an arched ice structure construction method, and relates to an ice structure construction method. The arched ice structure construction method aims to solve the problems that the construction period of an ice building is long, the ice building limits the structural span and height, and the structural form is single. The arched ice structure construction method is operated according to the following steps that step 1, a connecting unit mold is manufactured; step 2, connecting units are manufactured; step 3, a mesh structure is connected; step 4, the mesh structure is laid; step 5, filling with composite blocks is performed; step 6, liquid composite water is sprayed; step 7, the composite water is sprayed to the inner cambered surface of an arch-shaped body; and step8, surface treatment is performed. The arched ice structure construction method is used in the field of ice structure construction.
