广西百色澄碧河和永乐大桥 ,原设计为汽 -2 0 ,挂 -1 0 0刚架拱桥 ,后因年久失修有病害 ,多处发生裂纹。现为运输总重 42 5 2kN的超大构件的需要 ,应用粘钢加固技术对其进行了补强 ,使桥梁承载力大幅度提高。重点介绍粘钢加固设计、粘钢加固方案及施工工艺。
Guangxi Baise Chengbi River and Yongle Bridge, the original design for the steam -2 0, -100 0 frame rigid frame arch bridge, after a long disrepair disease, cracks occur in many places. Now the total weight of 42 5 2kN transport needs of large components, the application of steel reinforcement technology to reinforce it, so that greatly enhance the bearing capacity of the bridge. Focus on steel reinforcement design, steel reinforcement program and construction technology.
