目前,无缝线路中修破底清筛道床有两种方法:一种是“筛匣——方枕——筛底”的“两步走”手工清筛;另一种是用小型枕底清筛机清筛。在清筛过程中列车限速通过。 清筛道床作业对轨道的稳定性及强度影响比较大,必须采取适当的措施,以保证行车安全。为此,我们与北京局一起,在京广线保定工务段管内,50公斤/米钢轨、钢筋混凝士轨 At present, there are two ways to repair the bottom of the seamless line track bed: one is the “two-step” manual screening of “sieve box - square pillow - the bottom of the sieve”; the other is to use a small pillow Clear the bottom of the sieve machine. In the process of cleaning the train speed limit passed. Clean track bed operation of rail stability and strength of the relatively large impact, we must take appropriate measures to ensure traffic safety. To this end, we and the Beijing Bureau together, in the Beijing-Guangzhou line Baoding work section pipe, 50 kg / m rails, reinforced concrete rails
