| Abstract: | Taking the engineering of the soft foundation for DK55-DK67 Section of Tianjin-Baoding Railway reinforced by cement mortar mixing pile as the example，the technological test，construction process and specifications relating to cement mortar mixing pile are described，and the construction quality inspection and control points are generalized.The on-site inspection result shows that the cement mortar mixing pile has such high strength that the bearing capacity of the soft foundation so reinforced is improved；and the effect of such reinforcement is good enough to meet the requirement of foundation treatment for 200-250km/h PDL and line for mixed passenger and freight traffic. |
