针对我国客运专线铁路双块式无碴轨道施工,研制开发了组合轨道排架等成套工装设备和工艺,提出“定点定位,两点一线,顺序进行,由远及近”的无碴轨道几何尺寸精细调整方法。组合轨道排架就位准确、刚度大,可以多次循环使用。该施工方法通过在温福铁路上的应用,施工过程控制和最后的换轨检测表明,轨道的结构形位满足验标要求,达到了客运专线铁路无碴轨道高精度施工要求。
In view of the construction of ballastless track of double-track railroad for passenger dedicated railway in our country, the complete set of equipment and technology such as combined orbit rail-laying has been researched and developed, and the ballastless track of “fixed point positioning, two points first line, orderly, far and near” Geometrical size fine adjustment method. Combined rail rack in place accurate, large stiffness, you can use multiple cycles. Through the application on the Wenfu railway, the construction process control and the final test of track change, the construction method shows that the structural shape of the track meets the inspection requirements and meets the requirements of high-precision ballastless track construction on passenger dedicated railway.
