钢筋混凝土管的注浆加固顶管施工

Foundation Consolidation by Mortar Pouring into R.C. Pipe for Pipe Jacking Construction

介绍了在戈壁土土质不稳定和地下水渗流量大的情况下,进行人工掘进顶管施工的基础加固方法。实践证明,基础经小导管注浆加固处理后,其顶进过程与原状、无地下水戈壁土的基本相同,达到了预期的目的。

Under the unsteady soil and great amount of groundwater seepage flow in the Gobi De-sert, the foundation consolidation method for driving and pipe jacking construction was introduced. The engineering practice proves that after the foundation is consolidated by mortar pouring into pipe, pipe-jacking course is about the same as that in the original gobi desert soil without groundwater, and the desired result is achieved.
