Research on the Wall Crack Grouting Technology of Brick-Concrete Structure

Abstract:

Wenchuan earthquake caused a large number of masonry structure cracks, crack grouting become a very important link in the process of engineering structure reinforcement repair. This paper makes the statistical analysis on the structural seismic damage crack characteristics first, then determine the mechanism and characteristics of the cracks. Analysis of the reinforcement and repair mortar bond strength and practical range, put forward some requirements for crack repair and grouting material. Combined with grouting equipment, formed an earthquake damage of structure crack grouting construction technology in practical engineering , set up a complete system of grouting technology. Have a positive effect for the long-term development of repair reinforcement technology in China.
