Novel rail laying method for ballastless rail of newly-built high-speed railway
The invention discloses a novel rail laying method for a ballastless rail of a newly-built high-speed railway, and relates to the technical field of rail construction. The method comprises the steps:carrying out rough laying of a rail plate, after rough paving, carrying out fine tuning of the rail plate; Re-testing each rail bearing platform of the rail plate; enabling professionals to calculatea real model of each rail bearing platform and export a material schedule; requesting a material department to purchase adjusting stop blocks and gaskets according to the specific model and quantity of the adjusting stop blocks and the gaskets which are actually used; laying the adjusting stop blocks and the gaskets on all the rail bearing platforms in advance according to the scheme; performing rechecking and error correction according to the material detail table; laying long rail bars by using a rail layer, welding, diffusing prestress, and locking rails; and carrying out small-range fine adjustment and defect elimination on the local deviation rail bearing platform, so as to enable the local deviation rail bearing platform to meet the high-speed rail technical standard. The rail platelaying quality can be truly reflected, data are provided for the next procedure, the work efficiency and accuracy of placing the adjusting piece are improved, resource waste is reduced, and practicability is higher.
一种新型的新建高速铁路无砟轨道铺轨方法，本发明涉及轨道施工技术领域，进行轨道板的粗铺，粗铺后，对轨道板进行精调；对轨道板各个承轨台进行复测；专业人士计算出每个承轨台真实型号并导出材料计划表；根据实际使用的调整挡块和垫片的具体型号和数量报请材料部门采购调整挡块和垫片；按照方案预先对每个承轨台铺装调整挡块和垫片；对照材料明细表复核和纠错；用铺轨机铺装长轨条并焊接、预应力放散、锁轨；对局部偏差承轨台进行小范围的精调和消缺，使之符合高铁技术标准。能真实反应轨道板铺设质量，为下一道工序提供数据，提高了安放调整件的工效、准确率，降低资源浪费，实用性更强。
