A basic study on the standardization of epoxy injection in cracks of tunnel concrete structures

In this status no inspection standard of quality in repair of present concrete structure has a problem to repair for simple experience. In this paper for this problem improvement, it made an analysis of relation to injection quantity of crack width, injection time of crack width, injection pressure of crack width, injection pressure and time, injection quantity of structural size, injection quantity of structural individual crack position, injection time about crack width. and structural thickness. The data gained in analysis result be judged that it will help in systematic quality control about concrete structural repair.
