浙江某冷冻厂500吨冷库于1982年建成投产。1987年,在主库的结冻间与贮冰库的隔墙上+4.65m标高处发现横向通长(库房纵向全长)裂缝。见图1《原设计结冻间剖面图》。不久,裂缝处墙体粉刷剥落,墙砖酥松,绝热层受潮并结满冰霜,防潮隔汽层破损,后来又在结冻间与冷藏库隔墙的4.65m标高处发现同样的横向通长裂缝,但墙体破损程度稍轻微些。 A 500-ton cold storage plant in Zhejiang was completed and put into production in 1982. In 1987, the horizontal length (full length of the warehouse) crack was found at the elevation of +4.65m above the partition wall between the frozen storehouse and the ice bank of the main storehouse. See Figure 1 “The original design frozen section profile.” Soon, the walls of the cracks were exfoliated, the walls were crisp, the thermal insulation layer was damp and covered with frost, and the vapor barrier layer was damaged. Later, the same transverse length cracks were found at the 4.65m elevation of the freezer partition wall. , but the wall is slightly less damaged.
