A method for preventing and controlling cracks in masonry walls of strong vibration ramps

Abstract

The invention relates to the technical field of repairing cracks in walls, and discloses a method for preventing and treating cracks in masonry walls of strong vibration ramps. The prevention and control method includes the steps of: construction preparation, crack marking, base treatment, steel nail injection, crack surface cleaning, and crack sealing , fastening with steel nails, pre-embedding with steel nails, hanging carbon fiber mesh, roughening the surface, plastering, and restoring with putty powder paint. The inner and outer layers of the carbon fiber mesh work together to improve the integrity and structural strength of the wall, and carry out overall strengthening treatment on the inside and surface of the cracked masonry to ensure the integrity and structural strength of the cracks, and evenly disperse the deformation on the entire wall, increasing The ability to jointly resist deformation has greatly reduced the impact of vibration on wall cracking. This prevention method prevents cracks from appearing again after crack treatment, effectively guarantees the quality and appearance, and avoids the cost increase and construction period caused by repeated repairs. issues such as extension.

Description

technical field [0001] The invention relates to the technical field of repairing cracks in walls, in particular to a method for preventing cracks in masonry walls of strong vibration ramps. Background technique [0002] With the rapid development of my country's economy, more and more large-scale commercial complexes appear, especially in economically developed areas. During the construction period, many large-scale machinery and construction vehicles use the garage ramp to pass, and the traffic frequency is high and the load is heavy. The strong vibration has damaged the walls that have been built on both sides of the ramp and caused the walls to crack. Most of the existing wall crack repair technologies are chiseled and hung with glass fiber mesh plastering for repair. The stability of the wall structure formed by this type of repair technology is still poor, and the repaired wall will continue to crack under strong vibration. , resulting in increased cost and extended co...

AI Technical Summary

Problems solved by technology

During the construction period, many large-scale machinery and construction vehicles use the garage ramp to pass, and the traffic frequency is high and the load is heavy. The strong vibration has a destructive effect on the completed walls on both sides of the ramp, resulting in cracking of the wall.

Most of the existing wall crack repair technologies are chiseled and hung with glass fiber mesh plastering for repair. The stability of the wall structure formed by this type of repair technology is still poor, and the repaired wall will continue to crack under strong vibration. , causing problems such as increased cost and extended construction period caused by repeated repairs
