容积在400m~3以下的中小型球罐,国内基本采用桔形分瓣.现场安装大多数采用分带组装法。大环缝是最后组对的环口,其环口拘束力大,又积累了球带组对及球片的全部偏差,因而大环口的组对是带装法施工质量的关键。1.对组装平台及划线胎架的控制组装平台的地基应平整,坚实。平台要找好水平,水平误差不得大于10mm。为确保平台的刚度,其钢板的厚度要求为18～24mm,平台下部所垫的道木、钢轨间距要摆放合理.
The volume of small and medium-sized spherical tank below 400m ~ 3, the basic use of orange-shaped sub-valve. Field installation most of the use of sub-assembly method. The large ring seam is the last group of ring mouth, the ring binding force, but also accumulated the ball band group and the ball all the deviations, so the group of large ring mouth is the key to the construction quality of banding method. 1. Control of assembly platform and scribing tire rack The foundation of assembly platform should be smooth and solid. Platform to find a good level, the level of error shall not exceed 10mm. In order to ensure the rigidity of the platform, the thickness of the steel plate is required to be 18 ~ 24mm. The spacing between the road wood and the rail laid under the platform should be reasonable.
