1987年5月在京广线广州工务段管内试铺了采用新材料胶固螺栓的冻结接头线路和胶固绝緣接头,辙叉趾部、跟部等接头螺栓,经过2年多的实践,通过总重0.12Gt以上,证明效果显著,为保证运输安全和延长轮轨使用寿命,减少机车动能损耗,及扩大运输能力创造了条件。一、课题的提出近10年来,随着运量的不断增长,我局多数线路超大修周期,1987年统计超负荷运行线
In 1987 May in Guangzhou Guangshuang Guangzhou section of the pipe trial of the new material with a solidified bolt of frozen joints line and plastic insulation joints, frog toe, heel and other joint bolts, after more than two years of practice, Through the total weight of 0.12Gt or more, proved effective, in order to ensure the safety of transport and extend wheel-rail life, reduce locomotive kinetic energy loss, and to expand transport capacity to create the conditions. First, the proposed topic In the past 10 years, with the growing volume of traffic, most of the Board overhaul cycle line, in 1987 the statistical overload line
