The superiority of post-grouting is more and more proven by practice and recognized by people, and thus has developed rapidly in recent years. Post-grouting pile grouting is in the hole, perfusion before the concrete, put into the hole 1-2 hole until the end of the grouting tube until the concrete pile to a certain strength, with high-pressure grouting pump through the grouting tube And ejector to the pile bottom and piles into the cement slurry pressure process. Post-pile grouting process, ...
