CGM high-strength non-shrinkage grouting material used in the points for attention during the secondary grouting

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material prices secondary grouting, CGM high-strength non-shrinkage grouting material should meet the following requirements. (1), secondary grouting, CGM high-strength non-shrinkage grouting material from one side or both sides of the adjacent than for grouting, straight to the overflow so far from the other side, the exhaust for grouting. Grouting will be made from the four side and at the same time. (2), the grouting began, should be carried out continuously, not continuous. And shorten the grouting time as much as possible. (3), it is strictly prohibited in the process of grouting vibrating. Necessary available grouting boosters along grouting layer at the bottom of the HGM grouting material, are strictly prohibited from grouting layer, the upper, to ensure that grouting layer uniformity. (4), equipment foundation after grouting, should be 3 - after grouting 6 hours up along one edge of the device to cut 45 degree Angle ( See image below) In order to prevent the free end cracks, such as unable to handle trimming, should be 3 - after grouting After 6 hours with a spatula grouting layer surface pressure light. (5), when grouting layer thickness of more than 150 mm, should adopt pisolite rugged CGM high-strength non-shrinkage grouting material. 6, when large amounts of equipment foundation grouting, pisolite rugged grouting material mixing mechanical agitation modes should be adopted to ensure the grouting construction.
