摘要
结合双块式无砟轨道的结构特点,对其施工方案及其原理、施工工艺流程以及具体施工要点作了介绍,并对精确和固定轨道的几何尺寸及空间位置进行了详细的论述,从而为双块式轨枕预制积累了经验。
Combining with the structure characteristics of double block unballasted track, the author introduces its construction scheme and principle, construction technology schedules and concrete construction important points, and discusses geometry size and spatial position of exact and fixed track in detail, thus accumulating experiences for double block track sleeper prefabrication.
