摘要:
受施工阶段各种因素影响，高速铁路无砟道床施工后，轨道几何尺寸难以一次达标，需要通过钢轨扣件系统对轨道反复精调后，方可达到验收标准。然而，不同的精调作业方法会导致精调作业遍数及扣件更换数量的不同，影响精调效率。本文阐述了不同类型无砟轨道结构扣件系统的轨道线路精调原理、施工技术要求、作业技术标准、质量控制，并结合京沪、哈大、京石、西宝、郑徐等高速铁路联调联试前无砟轨道线路精调施工实践，研究开发了轨道高效精调施工方法及技术标准，可为类似工程及高速铁路养护维修提供参考。
Abstract:
Due to influence of various factors in the construction stage, after the construction of the high-speed railway ballastless track bed, the geometrical size of the track is difficult to reach the standard once, the track needs to be repeatedly tuned to meet the acceptance standard by using rail fastening system. However, the different fine adjustment methods will lead to different number of fine adjustment operations and the fasteners replacement, and affect the fine adjustment efficiency. The paper elaborates the principle of fine adjustment, the construction technology requirement, the operation technical standard and the quality control of the track line of different types of ballastless track structure fastening system, combined with Beijing-Shanghai, Haerbin-Dalian,Xi’an-Baoji, Zhengzhou-Xuzhou and other high-speed railway ballastless track line fine adjustmentconstruction practice before the test.
