摘要
以某单线普速铁路路基为研究对象,通过调研路基现场设计室内试验,验证基于电化学的处理方法对路基排水设备损坏、路基沉降及翻浆冒泥三种病害的整治效果。结果表明:电化学排水胶结对路基翻浆冒泥和基床下沉外挤病害整治有效且适用,提出了电化学排水胶结联合机械注浆封闭的铁路路基病害整治方法,并进一步探讨研究了该方法的施工工艺,得出了较为完善的路基病害治理方案。
Taking the single-track normal-speed railway roadbed as the research object,by investigating the roadbed site,the indoor test is investigated to verify the effect of remediation of the electrochemical treatment method on the roadbed diseases,namely,roadbed drainage equipment damage,roadbed settlement and mud boiling,The results show that electrochemical drainage cement is effective and applicable to the treatment of roadbed mud boiling and subgrade sinking and external squeeze diseases.A method for repairing railway roadbed diseases with electrochemical drainage cementing combined with mechanical grouting sealing is proposed,and the construction technology of this method is further discussed,getting a complete set of roadbed disease treatment program.
