一种用于处理铁路低矮路堤深厚软土地基的桩基制造技术

本实用新型专利技术公开了一种用于处理铁路低矮路堤深厚软土地基的桩基，包括：位于路堤核心受力区外的复合地基，所述路堤核心受力区为无砟轨道支撑层两侧45°扩散角范围内下面区域，所述复合地基顶面设有碎石垫层，该碎石垫层中间还设有土工格栅，位于路堤核心受力区内设有钻孔灌注桩，该钻孔灌注桩桩顶上设有钢筋混凝土连续薄板梁。本实用新型专利技术通过在位于路堤核心受力区内加设钻孔灌注桩，并在该钻孔灌注桩桩顶上加设钢筋混凝土连续薄板梁，解决了由于某些深厚软土地段受外部因素的影响无法设置桥梁，导致常规的地基处理方法无法满足无砟轨道的沉降控制要求和难以保证基床在列车动荷载长期作用下的稳定性的问题。适用于高速铁路深厚软土地基的处理。（*该技术在2021年保护过期，可自由使用*）

Pile foundation for treating deep soft soil foundation of railway low embankment

The utility model discloses a pile for treatment of low embankment, railway soft soil foundation including composite foundation in embankment core stress area, the embankment core stress zone for ballastless track on both sides of the support layer 45 degrees below the regional diffusion angle range of the composite foundation are arranged on the top surface of the gravel cushion the middle of the gravel cushion, with geogrid, embankment is located in the core force in a bored pile, the bored pile top is provided with a reinforced concrete continuous beam plate. The utility model in the core stress zone in the embankment with bored piles and reinforced concrete continuous beam and thin plate in the bored pile top, solved due to some deep soft soil section affected by external factors to set the bridge, resulting in foundation treatment of conventional methods can not satisfy the settlement of ballastless track the control requirements and to ensure the stability of Subgrade under train load long-term problems. It is suitable for the treatment of deep soft soil foundation of high speed railway.
