Among them, the wet method means that the steel and the component are bonded to the original component through latex cement, epoxy resin and other adhesives, and the newly added steel and the original component form a whole and work together. The dry method means that the newly added steel and the original member are not bonded with an adhesive, which cannot guarantee the effective transmission of the shear force of the joint surface. In the earthquake-resistant reinforcement, the wet-type outer steel reinforcement method is generally adopted.It is suitable for strengthening reinforced concrete beams, columns and brick columns, brick chimneys, etc., but the reinforcement process for round and curved members is relatively complicated. It has the advantages of convenient construction, less on-site workload, and can effectively improve the seismic performance of components. Its advantages are convenient construction, less on-site workload, and reliable stress. The disadvantage is that the amount of steel used is large, and the cost of reinforcement and maintenance is high. When chemical grouting is used to reinforce steel, the surface temperature of the section steel should not exceed 60 degrees; when the environment has corrosive media, there should be reliable protective measures.
