Rapid replacement method for ballast bed of concrete-filled steel tube sleeper type ballastless track
The invention discloses a rapid replacement method for a ballast bed of a concrete filled steel tube sleeper type ballastless track, and belongs to the technical field of railway tracks. According to the replacement area and the construction resource configuration, dividing replacement units; concrete between sleepers in the construction replacement unit is removed; concrete around the sleepers in the construction replacement unit is removed; support concrete at the bottom end of each sleeper is removed; rearranging the concrete-filled steel tube sleepers, and re-pouring the ballast bed; and the process is repeated until the replacement of all the construction replacement units is completed. According to the rapid replacement method for the concrete-filled steel tube sleeper type ballastless track bed, when a foundation below a track line has defects, rapid and accurate treatment of a damaged track can be achieved, traffic and driving safety are not affected in the time period outside a skylight in the damage treatment process, the risk of overall replacement is reduced, and the service life of the damaged track is prolonged. And more complicated transition measures are not needed.
本发明公开了一种钢管混凝土枕式无砟轨道道床快速置换方法，属于铁路轨道技术领域，所置换的道床内设置有钢筋网；根据置换区域以及施工资源配置划分置换单元；清除施工置换单元中各个轨枕之间的轨枕间混凝土；清除施工置换单元中各个轨枕周围的轨枕周围混凝土；清除各个轨枕底端的支撑混凝土；重新布置钢管混凝土轨枕，并重新浇筑道床；并重复循环上述过程，直至完成所有施工置换单元的置换。本发明提供了一种钢管混凝土枕式无砟轨道道床快速置换方法，能够在轨道线下基础出现缺陷时，能够实现对病害轨道的快速准确的处理，并在病害处理过程天窗以外的时间段中不影响通车及行车安全，降低了整体置换的风险，更无需较为复杂的过渡措施。
