莫斯科林学院木材陆运教研组为确定钢轨联组的最适宜长度,做了一些试验,其结果表明:由于森铁的上层结构较差,遇到18000—20000公斤的纵向温度压力时,线路可能发生涨轨,这限制了焊接钢轨联组的长度。根据计算,在联组为16米长的范围内,森铁钢轨的接头焊接是完全可能的,而且不致使线路的养护工作复杂化。根据在各地进行试验获得的数据,森铁钢轨的年
In order to determine the most suitable length for the rail joint group, some experiments have been carried out. The results show that the line may go up when it meets the longitudinal temperature pressure of 18000-20000 kg due to the poor superstructure of Mori Iron & Rail, which limits the length of the welded rail joint. It is calculated that it is entirely possible to weld the rail of the Mori rail within the range of up to 16 meters in length and without complicating the maintenance of the circuit. According to the data obtained from experiments carried out in various places, Mori rail has a year
