When the newly poured cement ground snows, the thermal insulation measures of "keeping in good health by warm shed method" should be taken as soon as possible;

The thermal insulation and maintenance of pouring cement adopts the greenhouse method: a greenhouse is built around the structure with steel pipes and sealed with adhesive tape. The greenhouse must be firm and airtight, covered with straw strips and heated by a coal-fired heater. The exhaust pipe of the furnace must be led out of the greenhouse to discharge the flue gas to the outside of the greenhouse to prevent gas poisoning and accelerate the carbonization of concrete with excessive carbon oxide concentration. The bottom temperature in the greenhouse should not be lower than 5℃. When it is lower than 5℃, the method of increasing coal stoves should be adopted. During the curing period of pouring cement, assign special personnel to check the coal stove, add coal and keep warm.
