1982年我厂接受了建造两台一万m~3外浮顶油罐的任务,为高质量高速度建成油罐,我们根据外浮顶油罐的结构特点,提出利用油罐的浮顶进行水浮顶升倒装法施工。我们是第一次模索使用这种方法,但实践证明这是一种既经济又有效的好方法。一、工程概况罐体容积101.11m~3,罐体直径28500mm,罐高15850mm,金属总重198.616t,罐体壁板实际排板为10层,其厚度自下而上分别为16(板宽2150mm)、15、14、12、10、8、6、6、6、6mm,罐底中幅板厚6mm,边缘板厚8mm。浮顶由环形浮舱与单盘构成,直径为28100mm,距离罐壁间隙为200mm,采用机械密封。环形浮舱由型钢和
In 1982, our factory accepted the task of building two 10,000 m ~ 3 floating roof tanks and built the tanks for high quality and high speed. Based on the structural characteristics of the floating roof tanks, we proposed the use of floating roofs Float or flip flops construction method. We were the first to use this method, but it proved to be a good and cost-effective method. First, the project overview Tank volume 101.11m ~ 3, the tank diameter of 28500mm, tank height 15850mm, total metal weight 198.616t, the tank wall plate actually 10 for the thickness of its bottom-up were 16 (width 2150mm), 15,14,12,10,8,6,6,6,6 mm, the tank bottom width of 6mm, the edge thickness of 8mm. The floating roof is composed of an annular floating tank and a single plate, with a diameter of 28100 mm and a clearance of 200 mm from the tank wall, using a mechanical seal. Ring-shaped float by the steel and
