In what circumstances should mass concrete be buried with cooling pipes?
When the difference between inside and outside temperature difference is large, the cooling pipe can be embedded.
Hydration heat is too large, external facilities can not guarantee the temperature difference between the internal and external, must be set.
If the heat is too great, the external facilities can not guarantee the temperature difference between inside and outside, and the cooling pipe can be embedded.The commodity concrete pouring starts after finishing collecting, controlling the surface shrinkage crack, reduce the evaporation of water, and after the final setting of concrete began to cover maintenance, general merchandise within 12h after the concrete pouring and curing insulation covering, covering two layer straw bags, around two pile caps and surface layer of nylon film, straw bags under staggered, overlapping, open all the surface covered, forming a good insulation layer, and should be kept in a nylon film condensation water.
