钢筋混凝土桥运营过程中,常常需要对因裂缝而损坏的结构整体性进行修复,为提高梁的承载力而进行混凝土补强,在安装护拱和更换变形缝时敷设锚固钢筋和补强路缘石等。所有这些工作,都可以利用环氧胶来实现。为了恢复因裂缝而损坏的结构整体性,可将环氧胶压入裂缝里。环氧胶的成分采用如下(按重量计):标号—20的环氧树脂为100,呋喃基甲醇—20,聚乙烯聚(西安)—8～25。按照混凝土的温度加入聚乙烯聚酸(按重量计);温度20℃时为
Reinforced concrete bridge operation process, often need to repair the integrity of the structural damage caused by cracks in order to improve the bearing capacity of the concrete reinforcement, the installation of arches and replacement of deformation of the laying of anchorage reinforcement and curb Wait. All of this work can be done with epoxy glue. In order to restore structural integrity damaged by cracks, epoxy glue can be pressed into the cracks. The composition of the epoxy glue is as follows (by weight): the epoxy resin of the symbol -20 is 100, furanyl methanol -20, polyethylene poly (Xi’an) -8 ~ 25. According to the temperature of concrete to join polyethylene polyacid (by weight); temperature of 20 ℃ for
