Description

TECHNICAL FIELD

[0002] In modern construction engineering, the construction of mass concrete members is a common link. However, during the hardening process of concrete, a large amount of heat will be released due to cement hydration reaction, causing the internal temperature of concrete to rise rapidly. If this temperature rise is not controlled, the temperature difference between the inside and outside of the concrete will be too large, and then a large thermal stress will be generated. When the thermal stress exceeds the tensile strength of the concrete, cracks will be generated on the surface or inside of the concrete, seriously affecting the safety and durability of the structure.

[0003] To solve this problem, the traditional method is to pre-bury cooling water pipes in the concrete, and to absorb the heat inside the concrete by circulating cooling water, thereby reducing the internal temperature of the concrete. However, the existing cooling method has some problems. For example, the application patent CN220868885U uses dry ice as a cooling medium, although the cooling effect of dry ice is significant, but its cost is high, and special attention should be paid to safety during use, because dry ice will release a large amount of carbon dioxide gas during sublimation, if used in an environment with poor ventilation, it may pose a threat to the health of construction personnel. In addition, the storage and transportation of dry ice require strict requirements, special insulation equipment is needed, which further increases the cost and the complexity of operation. Therefore, the utility model provides a concrete cooling and temperature reducing device with low cost, safety and reliability, convenient storage and transportation, to effectively control the temperature of mass concrete members during construction process, and prevent cracks.
