破损露筋混凝土结构修复工艺研究

Research on Repair Technique for Damaged Concrete Structure with Exposed Reinforcing Bars

介绍桥梁结构钢筋混凝土破损露筋修复工艺,通过对破损处钢筋进行除锈及涂漆,使其表面形成致密的涂层,阻止有害介质与钢筋接触,使钢筋得到更好的保护。该施工工艺具有较好的防腐性,能避免干缩裂纹的产生,可在桥梁破损修复工程中推广应用。

This paper introduces the repair technique for damaged concrete structure with exposed reinforcing bars. By rust cleaning and painting reinforcing bars at the damages , a dense coating is formed on the surface of reinforcing bars to block contact of harmful media with reinforcing bars so as to protect reinforcing bars better. This construction technique exhibits good anti-corrosive properties and can avoid generation of drying shrinkage cracks and can be popularized in the projects of repairing bridge damages.
