Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a cooling device for pouring large-volume concrete. Background Art

[0002] The strength grade of large-volume concrete is relatively high, and the unit cement consumption is large. The hydration heat and shrinkage can easily cause cracks in the structure, so it is necessary to optimize the mix ratio to pre-control the cracking of concrete. Since the hydration heat of cement in large-volume concrete is not easy to dissipate quickly, the heat is stored inside, causing a large temperature rise, which is prone to cracks caused by temperature.

[0003] Existing large-volume concrete is usually cooled by pre-buried cold water pipes in which water circulates. The outer side of the concrete dissipates heat faster due to its large surface area, while the inner part of the concrete dissipates heat more slowly, which easily leads to excessive temperature difference between the inside and outside of the concrete and causes cracks.
