Description

Technical Field

[0001] The utility model relates to the field of mass concrete temperature control devices, and more specifically, to a mass concrete temperature control device. Background Art

[0002] After pouring large-volume concrete, the hydration heat of cement will cause the internal temperature of the concrete to rise significantly, and the maximum temperature can reach 60-80℃, and sometimes even exceed 90℃. The heat dissipation on the concrete surface is relatively fast, so the concrete forms an internal and external temperature difference, which causes compressive stress inside the concrete and tensile stress outside. The elastic modulus and tensile strength of concrete in the early stage are very low, so cracks are easy to appear on the concrete surface, affecting the safety of the building. The commonly used concrete temperature control technology is the cooling water pipe method, which uses cold water to absorb the hydration heat of concrete and control the maximum temperature of concrete;

The multi-angle section design structure has no problem cooling during the cooling cycle. However, when it is not used after cooling, the pipe design of the angle structure cannot drain the water inside cleanly, resulting in a different temperature difference between places with water and places without water, which affects the quality of concrete.
