钢混结构修补加固技术在技改工程中的应用

针对不同情况，可采用表面密封法、嵌缝密封法、灌浆修补法对混凝土结构裂缝进行修补，可采用涂抹砂浆法、化学灌浆法、局部修补法、喷射混凝土法对混凝土结构受损伤部位进行修补，可采用增大截面法、外包钢法、粘钢法、增设剪力墙法、外加力法对混凝土结构进行加固，以达到防渗、防漏、提高结构承栽力的目的。

The Application of the Repairing and Reinforcing Techniques for Steel- concrete Structure in Technical Transformation Engineering

Accounting to the different circumstances, the surface sealing met ho d, the filleting sealing method and the grouting repairing method can be used to repair the cracks of the concrete structure; the plastering method, the chemica l grouting method, the partial repairing method and the concrete ejecting method can be used to repair the damaged positions of the concrete structure; and the section enlarging method, the external steel covering method, the steel adhering method, the shear wall extending method and the external force applying method can be used to reinforce the concrete structure. And all these methods will be u sed to achieving the seepage control, the leak prevention and the increase of th e bearing capacity of the structure.
