Application of Cement Mixing Pile in Soft Foundation Treatment in Huanghua Port Ore Terminal

LI Yulei;Tianjin Research Institute for Water Transport Engineering;  
Due to its characteristics of convenient construction,low cost and strong soft soil strengthening capacity,cement mixing pile has been widely used in China and has achieved good economic and social benefits.However,researches on its reinforcement mechanism and failure mechanism are yet to be completed. In practical engineering,problems occur frequently,resulting in unfavorable project progress.Combined with the construction status of track beam foundation in Huanghua Port Ore Terminal,such as geological engineering and soft soil layer distribution in sites,the pile forming process was optimized and a "Two Four Jet Mixing" construction process by a single axis bidirectional mixing pile machine was adopted according to on-site technical seminars,experts' guidance and detection schemes.In the end,factors influencing the strength of cement mixing piles were also presented.
