Engineering and technical personnel are always been plagued by drilling the hole and the rapid construction of technology In loose broken, serious overhead formation. In order to solve low rate of drilling anchor hole in the dam accumulation body, carrying on the solid wall grouting test, adding a certain amount of accelerating and calcium sulfate to Ordinary Portland cement, Improving the slurry setting time and compressive strength. As a result, It plays a good solid wall grouting effect, Improves the efficacy of the construction of anchor cable hole, and get a good use in the slope control.
