High-speed rail roadbed settlement repairing method and operation system
The invention provides a high-speed rail roadbed settlement repairing method and an operation system. The high-speed railway subgrade settlement repairing method comprises the steps that S1, geological investigation is conducted firstly, a comprehensive drilling scheme is utilized, a deep soil sample is obtained for each preset drilling position, the shear strength, consolidation parameters and compression modulus of soil are analyzed, underground cavities, cracks or other hidden dangers are detected through a geological radar and a sound wave comparison instrument, and a foundation is built; and S2, hydrological exploration is carried out, a long-term underground water level observation well is installed, observation is carried out in different seasons, seasonal changes of the underground water are known, and the interaction between the underground water and the roadbed soil body is evaluated. The roadbed of the railway is comprehensively inspected and measured, grouting is conducted through an adaptive method, the problems of water drainage, blockage and supporting force reduction are solved, and then the problem that long-term and repeated repairing is needed is avoided.
本发明提供一种高铁路基沉降修复方法及作业系统。该基于一种高铁路基沉降修复方法，包括，S1、首先进行地质勘察，利用全面的钻探方案，针对每个预定的钻孔位置，获取深层土样，分析土壤的抗剪强度、固结参数、压缩模量，再通过地质雷达和声波对比仪检测地下空洞、裂缝或其他隐患，S2、再进行水文勘查，安装长期地下水位观测井，在不同季节进行观测，了解地下水的季节性变化，评估地下水与路基土体的相互作用。通过对铁路的路基进行全面的检查、测量，通过适应的方法进行灌浆、并解决排水、堵塞、支撑力下降的问题，进而避免需要长期、反复的进行修复的问题。
