摘要
CFG桩软基加固是高富水淤泥质地层处理的一种手段,对提高高富水淤泥质地层承载能力和稳定性具有重要作用,为此提出高富水淤泥质地层中CFG桩软基加固施工技术研究。通过施工准备、长螺旋钻进成孔、泥浆制备、注浆成桩,完成高富水淤泥质地层中CFG桩软基加固施工。通过实际案例应用,加固后高富水淤泥质地层路基承载力得到了有效的提升,沉降变形得到了有效的控制,具有良好的加固效果。
CFG pile soft foundation reinforcement is a means of treating high water rich muddy formations,which plays an important role in improving the bearing capacity and stability of high water rich muddy formations.Therefore,a study on the construction technology of CFG pile soft foundation reinforcement in high water rich muddy formations is proposed.Through construction preparation,long spiral drilling into holes,mud preparation,and grouting into piles,the soft foundation reinforcement construction of CFG piles in high water rich muddy strata is completed.Through practical case applications,the bearing capacity of the reinforced high water rich muddy soil subgrade has been effectively improved,and settlement deformation has been effectively controlled,with good reinforcement effects.
