随着城市基础设施建设的发展,盾构工法因其拆迁量小、安全风险低、成本低、施工速度快等优点得以广泛运用,管片厂数量也随之剧增,据不完全统计,目前国内从事管片生产的企业已超过100家,每年仍有数十家新建工厂,且以自动化流水线生产技术为主流。然而自动化流水线的优点在生产过程中常因为一些技术问题难以发挥,有的生产线甚至长期带病生产,将缺陷转移至成品质量中。如何对自动化生产技术进行有效控制, With the development of urban infrastructure construction, the shield construction method has been widely used due to its small amount of demolition, low safety risk, low cost and fast construction speed. The number of the tube factories also increases rapidly. According to incomplete statistics, There are more than 100 domestic enterprises engaged in the production of segment pipes. There are still dozens of newly-built factories each year and the mainstream of production line automation technology is adopted. However, the advantages of automated assembly line in the production process is often difficult to play because of some technical problems, and some even prolonged sick production line production, the defects transferred to the finished product quality. How to control the automated production technology effectively,
