Construction method for high-speed rail roadbed arching treatment
The invention relates to the technical field of railway disease treatment construction, and concretely relates to a construction method for high-speed rail roadbed arching treatment. The method is used for arching the roadbed, and comprises the following steps: manually excavating working grooves in the two sides of a monolithic track bed in the line direction at the upper floating section of themonolithic track bed in order to make the monolithic track bed separated from a road shoulder and an inter-line sealing layer; cutting a cemented graded broken stone layer under the monolithic track bed in a segmented mode through a rope saw, and ejecting out the graded broken stone layer in a segmented mode in the vertical direction of a line through a hydraulic jack; temporarily supporting the monolithic track bed by using spiral jacking to enable the monolithic track bed to be in a suspended state; and finally, using a mechanical jack and a spiral jack to jack the falling track, and pouringconcrete under the monolithic track bed for filling to complete falling track fine adjustment work. The method has the advantages of low requirements on construction equipment, small human input, scientific and effective construction sequence, and capabilities of reducing pollution, saving cost, improving working efficiency and effectively realizing roadbed disease treatment. The method is mainlyapplied to the aspect of high-speed railway roadbed disease treatment.
本发明涉及铁路病害处理施工技术领域，更具体而言，涉及一种针对高铁路基上拱处理的施工方法。在路基上拱，整体道床上浮段先在整体道床两侧沿线路方向人工开挖工作槽，使整体道床和路肩、线间封闭层分离；其次利用绳锯分段切割整体道床下已胶结级配碎石层并用液压千斤顶沿线路垂直方向分段顶出级配碎石层；再次用螺旋顶托临时支撑整体道床使整体道床处于悬空状态；最后用机械千斤顶和螺旋顶托落道并浇筑整体道床下混凝土填充，完成落道精调工作。本方法对施工设备要求低，人力投入小，施工顺序科学有效，能够降低污染，节约成本，提高工作效率和有效实现路基病害处理。本发明主要应用在高速铁路路基病害处理方面。
