杂填石地基旋喷二次注浆成桩加固施工

Secondary rotary grouting reinforcement construction of foundation backfilled with mixed stone

通过对杂填石地基利用旋喷设备及二次注浆成桩施工方法的研究和应用 ,解决了在杂填石地层中难以成桩的技术难题 ,达到了提高地基承载力和减少不均匀沉降的效果。

The application of secondary rotary grouting construction method in reinforcement treatment of the foundation backfilled with mixed stone is introduced, which solve the piling difficulties in such foundations. Reinforcement treatment not only improves the bearing capacity but reduce uneven settlement of foundation.
