Different engineering geological conditions are very different, and it is impossible to have the same grouting parameters. The preset grouting parameters often refer to the experience of similar projects. The final determination of the grouting parameters depends on The results of test piles, but there is not much experience that the country can learn from, needs further accumulation, coupled with theoretical discussions, to eventually form a mature technology.
Post-grouting of cast-in-place piles has the advantages of improving the bearing capacity of a single pile, increasing productivity, and saving construction funds. Therefore, promoting the post-grouting construction technology in qualified projects has important significance and broad prospects. .
