Inorganic high-strength grout hasthe advantages of good self-fluidity, fast hard, early strength, high strength, non-shrink, micro-expansion, and self-tightness, and it is non-toxic, harmless, without pollution to water quality and the surrounding environment, coupled with reliable construction quality easy operation, low cost, short du?ration, etc., it is widely used in engineering repair and strengthening.Combining with engineering example, overcom?ing the difficultiesin construction operation, small work space and other problems, after scheme optimization, this pa?per used a reverse pressure injection inorganic grout repair technique to repair and treatleakage ribs at thebottom of the box in this case, and introduced the construction process in detail. The results show that using the reverse pres?sure injection inorganic grout to repair leakage ribsat the bottom of the box has a good effect, worth of wide applica?tion and promotion.
