制盐工段所属车间包括蒸发车间、离心车间、凉水塔(冷却塔)、泵房等,由于多种原因,导致钢筋混凝土结构在1971年投产后三年出现裂缝,混凝土和钢筋被腐蚀。在1973年～1974年的短短一年中又发现7根梁、柱的裂缝延伸400～700毫米。此时,已发现有10根柱子因主筋锈蚀膨胀而导致保护层混凝土开裂,离心车间有两根承重梁因钢筋腐蚀膨胀使保护层胀裂,裂缝已延伸到梁
The workshops of the salt production section include evaporating workshops, centrifugal workshops, cooling towers (cooling towers), and pumping stations. Due to various reasons, cracks occurred three years after the reinforced concrete structure was put into operation in 1971, and concrete and steel bars were corroded. In just one year from 1973 to 1974, seven beams and columns were found to have cracks extending 400-700 mm. At this time, 10 pillars have been found to cause cracks in the concrete of the protective layer due to corrosion of the main ribs. There are two load-bearing beams in the centrifuge workshop, which cause the protection layer to expand due to the corrosion of the steel bars. The cracks have extended to the beams.
