Strengthening of beams and slabs with steel plate:1.substrate surface clean; 2.scribe line ro setting out; 3.anchoring; 4.plate surface preparing; 5.bonding steel plate with the structural adhesive; 6.maintaince; 7.checking; 8.protection coating

Beam 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.

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.

Although there are many ways to strengthen the bridge and improve the bearing capacity of the bridge, the basic principles are all the same, and all of them follow the basic principle of mechanics. From the angle of external factors and internal conditions of bridge structure to strengthening for improving the bearing capacity.

According to the investigation data, the cause of structure cracking in engineering practice is about 80% of the cracks caused by "deformation" or cracks caused by "deformation" as the main factor, and about 20% of the cracks caused by the "load" factors.
