Zusammenfassung:The invention discloses a temperature control method for concrete construction of a joint part of a dam and a diversion box culvert. The method comprises the following steps: 1, mixing auxiliary materials; 2, cooling the auxiliary material; 3, mixing the concrete; 4, cooling the initial concrete; 5, pouring concrete; and sixthly, concrete gaps are filled. By arranging the protective shed and the heat insulation layer, the situation that the auxiliary material is heated due to direct sunlight can be avoided, and meanwhile heat transfer between the ground and the auxiliary material can be avoided; the spraying head is used for directly spraying water for cooling, calcium chloride powder mixed in the auxiliary materials is combined, after the water is sprayed through the spraying head, the calcium chloride powder is melted when meeting water and absorbs heat in the auxiliary materials, and then the effect of reducing the temperature of the auxiliary materials is achieved. Initial concrete placed in the storage b
