Overall replacement method for concrete filled steel tube sleeper type ballastless track bed
The invention discloses an integral replacement method for a concrete-filled steel tube sleeper type ballastless track bed, which belongs to the technical field of railway tracks, is used for replacing the damaged concrete-filled steel tube sleeper type ballastless track bed, and comprises the following steps: detecting the ballastless track bed, and determining an area to be replaced; ballast bed concrete above the bottom end face of the sleeper in the to-be-replaced area is removed, and a longitudinal reinforcing connecting piece is installed; ballast bed concrete below the bottom end face of the sleeper in the to-be-replaced area is removed, and a transition supporting piece is installed; preparing a replacement track panel; the to-be-replaced track panel is moved out of the to-be-replaced area, and the replaced track panel is installed in the to-be-replaced area; and the ballast bed is poured again in the to-be-replaced area. According to the overall replacement method for the concrete-filled steel tube sleeper type ballastless track bed, rapid and accurate treatment of a damaged track can be completed when the concrete-filled steel tube sleeper type ballastless track bed has defects, traffic safety is guaranteed while traffic is not affected in the time period except the construction skylight period, and more complex transition measures are not needed.
本发明公开了一种钢管混凝土枕式无砟道床整体更换方法，属于铁路轨道技术领域，用于置换出现病害钢管混凝土枕式无砟道床，包括如下步骤：检测无砟道床，确定待置换区域；清除待置换区域内轨枕底端面以上的道床混凝土，并安装纵向增强连接件；清除待置换区域内轨枕底端面以下的道床混凝土，并安装过渡支撑件；制备置换轨排；将待置换轨排移出待置换区域，并将置换轨排安装在待置换区域中；在待置换区域内重新浇筑道床。本发明提供了一种钢管混凝土枕式无砟道床整体更换方法，能够在钢管混凝土枕式无砟道床出现缺陷时完成对病害轨道的快速准确的处理，并在施工天窗期以外的时间段不影响通车同时保证行车安全，更无需较为复杂的过渡措施。
