(二)梁桥加固广东省在七十年代初开始进行梁桥加固,包括悬臂桥梁,少筋微弯板桥,T形梁桥和连续梁板桥等,主要方法为: 1.用环氧树脂混凝土修补悬臂梁桥牛腿广东省内的一些悬臂梁桥,出现悬臂牛腿开裂的现象,其原因多是支座生锈,致使牛腿混凝土被拉裂。韶关地区在1973年开始,用环氧树脂修补了几座悬臂梁桥。如韶关市南门的浈江大桥,韶庾线的黄浪水桥和南雄县城的南门桥等,都是1956年修建六十年代已发现牛腿开裂的悬臂梁桥。先后于
(II) Strengthening of Beam Bridges Guangdong Province began strengthening beam bridges in the early 1970s, including cantilever bridges, less tendons, slightly bent bridges, T-beams and continuous beam bridges. The main methods are as follows: 1. Using epoxy Resin concrete repair cantilever beam bridge Some cantilevered beam bridge in Guangdong Province, the phenomenon of cantilever leg cracking, the reason is mostly rusty bearings, resulting in the concrete legs were cracked. Shaoguan area began in 1973, with epoxy repair several cantilever bridges. Such as the Han River Bridge in Shaoguan Nanmen, the Huanglang Water Bridge in Shaoguan and the Nanmen Bridge in Nanxiong County, were the cantilever bridges that were found in 1956 to have cracked corbels in the 1960s.
