铺设长度800m以上的长钢轨可提高无缝线路的稳定性,可减少维护温度调节器的劳动力消耗。对于“超长”长钢轨的铺设与锁定,特别重要的是使应力在其全长上均匀一致。为
Laying long rails longer than 800m increases the stability of a seamless line and reduces the labor required to maintain the thermostat. For the laying and locking of “long” rails, it is particularly important that the stresses be uniform over their entire length. for
