Bridge pile foundation construction method for high-speed railway karst
The invention discloses a bridge pile foundation construction method for high-speed railway karst. The bridge pile foundation construction method comprises the step that a karst cave is treated according to the height of the karst cave by adopting a throwing and filling method, a cast-in-place concrete filling method, a steel casing crossing method or a double-casing follow-up method. According to the bridge pile foundation construction method for the high-speed railway karst, the technical problems that due to the fact that karst caves are not classified, different treatment schemes cannot be adopted to achieve the optimal treatment effect on the karst caves, the construction period is long, and the project quality and economic benefits are low are solved.
本申请公开了一种用于高速铁路岩溶的桥梁桩基施工方法。该桥梁桩基施工方法包括：根据溶洞的高度采用抛填法、灌注混凝土填充法、钢护筒穿越法或双护筒跟进法进行溶洞的处理。本申请解决了由于没有给溶洞进行分类，也就不能采取不同的处理方案达到对溶洞的最佳处理效果造成的工期长，且工程质量和经济效益低的技术问题。
