一、概况1.这个技术条件是对大于950 m 长轨节无缝线路的补充规定,其它问题应按交通部1979年10月3日公布的《无缝线路铺设和养护的技术条件》及交通部有关规定的其它文件执行。2.超长轨节采用 P 65新轨或旧轨,允许铺设在直线和半径不小于600 m 的曲线上。3.轨节的锁定要在设计温度幅度范围内,尽量接近上限,并要高出下限12℃以上。4.由于工作和轨节温度变化的实际情况,对大于950 m 的轨节每一段都分别进行计
I. General 1. This technical condition is a supplement to the continuous track of more than 950 m long track, and other problems shall be in accordance with the “Technical Conditions for Laying and Maintenance of Seamless Track” promulgated by the Ministry of Communications on October 3, 1979 And the Ministry of Transportation and other relevant provisions of the implementation of the other documents. 2. Ultra-long track section using P 65 new or old track, allowed to lay in the straight line and the radius of not less than 600 m curve. 3. Rail section of the lock in the design temperature range, as close to the ceiling, and higher than the lower limit above 12 ℃. 4. Due to the actual situation of changes in temperature at work and railroad tracks,
