水泥砂浆桩在津保铁路软土地基处理中的应用
Application of Cement Mortar Mixing Pile in Treatment of Soft-soil Foundation of Tianjin-Baoding Railway
摘要
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 200-250 km/h PDL and line for mixed passenger and freight traffic.关键词
