摘要
拱脚预埋件是钢管拱桥梁中较为主要的连接方式,具备力学性能优越,安装稳定、牢固,容易施工定位,经济性优越,还能在一定程度上调节钢管拱的安装偏差等优点。围绕预埋件制作工艺,介绍制作流程以及遇到的重难点,采取的精度控制措施和工艺方法对拱脚预埋件制作的精度和效率起着关键性作用。
Arch foot embedment is the main connection method in steel pipe arch bridge. It has the advantages of superior mechanical properties, stable and firm installation, easy construction and positioning, superior economy, and can adjust the installation deviation of steel pipe arch to a certain extent. This paper focused on the production process of embedded parts, introduced the production process and the key difficulties encountered, and then adopted the precision control measures and process methods, which play a key role in the precision and efficiency of the production of embedded parts.
