There are many problems with existing bridge, for example, cracks, load increase, steel corrosions. So we need to strengthening and repair the bridge with structural strengthening system.
2020-03-27 15:41:58There are mainly 5 structural strengthening technology to strengthening bridges. 1) strengthening the weak components; 2) add auxiliary components; 3) change the structure system; 4) reducing the constant load; 5) reinforcement of pier and abutment and foundation.

2020-03-27 15:37:25Beam thickness strengthening method must ensure that the new and old concrete has higher bond strength. The main points are as follows: the base course of the original component joint surface should be solid, the surface is rough and clean, the shrinkage stress of the new cast concrete is small, and the bond performance is good.
