Leakage-proof treatment method for roof of curing barn

Abstract

The invention discloses a curing barn roof leakage-proof treatment method, which mainly comprises the following steps of: repeatedly smearing butter at a crack, spraying by using outer flame of a blast burner, ensuring that the butter can be completely melted, flows into the crack and is solidified, and repeating for three times to ensure that the periphery of the crack can be completely covered; the large bulk curing barn repairing technology has the advantages of being low in cost, easy to operate and the like, after the curing barn is repaired, the curing period can be shortened, the curing coal consumption is reduced, the available tobacco leaf proportion is increased, the curing barn maintenance cost of tobacco growers is invisibly reduced, and the income of the tobacco growers is indirectly increased.

Description

technical field [0001] The invention belongs to the technical field of routine maintenance of construction engineering, and in particular relates to a leak-proof treatment method for the roof of a barn. There are slight cracks on the purpose of the barn. Background technique [0002] Baking room is the most important part of infrastructure construction. During the baking process of large-scale dense baking room, the temperature of the wall surface close to the furnace body is high, while the temperature of the wall surface far away from the furnace body plummets, resulting in uneven heating for a long time. The cracking of the roof of the barn often occurs. At the same time, due to the continuous decline in the planting area of ​​tobacco leaves and the continuous transfer of the tobacco area in recent years, the investment in the construction of the barn has decreased.

[0002] Baking room is the most important part of infrastructure construction. During the baking process of large-scale dense baking room, the temperature of the wall surface close to the furnace body is high, while the temperature of the wall surface far away from the furnace body plummets, resulting in uneven heating for a long time. The cracking of the roof of the barn often occurs. At the same time, due to the continuous decline in the planting area of ​​tobacco leaves and the continuous transfer of the tobacco area in recent years, the investment in the construction of the barn has decreased. The cracking degree of the barn; for the cracked barn, tobacco farmers mainly adopt three methods to deal with it: laying white plastic oil paper, repairing with asphalt, and repairing with cement. Under the action of plastic, the aging of the plastic will be accelerated, and damage will appear after one month, and the repair effect is extremely unsatisfactory. However, the latter two types still have water seepage after repair because the asphalt and cement cannot fully fit the crack wall; the repair effect is very good. It is not ideal, the problems of air leakage and water seepage are still prominent, and the original repair method has a short service life, only 1-3 years. During the baking process of tobacco farmers, due to the existence of cracks in the barn, heat will overflow from the cracks, thus cracking The curing barn needs to consume more fuel, and the cracked barn will also seep into the barn during rainy days, resulting in serious greening, variegated colors, and ash on the roasted tobacco leaves, which has caused great losses to the tobacco farmers; Ash refers to indistinct gray or dark brown spots of different sizes that appear on the surface of tobacco leaves after roasting

This kind of tobacco leaf has weak burning power, peculiar smell, poor aroma quality, less aroma, stronger irritation and lower quality
