钢花管注浆技术在铁路桥涵过渡段病害整治中的应用

Application of Steel Flower Pipe Grouting Technology in Disease Treatment of Railway Bridge Culvert Transition Section

随着大轴重、大运量重载列车的不断开行,铁路桥涵过渡段发生沉降变形、路基下沉、道床翻浆冒泥等病害逐渐增多并日趋严重,尤其雨季,由于桥涵过渡段路基病害造成线路轨道几何尺寸难以保持,严重影响列车运行安全。结合朔黄铁路桥涵过渡段路基病害整治工程实例探讨钢花管注浆技术在此类病害整治中的应用,供建设单位、设计单位及施工单位参考。

With continuous operation of heavy haul trains with large axle load and large traffic volume,the diseases such as settlement deformation,subgrade subsidence and mud boiling of track bed in transition section of railway bridges and culverts gradually increase and become more and more serious,especially in rainy season,the geometric dimension of track is difficult to maintain due to subgrade diseases in transition section of bridges and culverts,which seriously affects safety of train operation.The application of steel pipe grouting technology in treatment of subgrade diseases in bridge culvert transition section of Shuohuang Railway is discussed,which can be used for reference by construction units,design units and construction units.
