随着国家高速公路网的规划及实施,公路建设等级标准的提高和与日俱增公路建设投资,公路桥梁建设资金在高速公路投资总额中占据约50%以上。预应力在桥梁上部构造中的应用达95%以上,预应力施工作为桥梁施工中的特殊过程控制,其中预应力筋管道的成型,质量控制,工艺控制,显得尤为重要。现将橡胶抽拔棒在T梁施工中的应用作简要的介绍。 With the planning and implementation of national highway network, the level of highway construction standards and the increasing investment in highway construction, highway and bridge construction funds accounted for about 50% of the total investment in highway. The application of prestressing in the structure of the upper part of the bridge reaches more than 95%. As a special process control of bridge construction, prestressed construction, of which the forming, quality control and process control of the prestressed tendons is particularly important. Now the application of rubber extraction rods in the T beam construction for a brief introduction.
