1.扣軌作业的操作順序;先将枕木間距勻好,再上內側扣軌的軌卡。上軌卡的时候是一个一个地将枕木下的道碴掏空,然后再上,即掏空一根上一根。上完后随即回填道碴,故并不影响行車安全。基本軌內側的軌束上齐后,再上外側軌束。由于內侧扣轨的軌束已全部上好,故可酌情多掏儿孔。这种作业,根据养綾規則第14条的規定,不需要在列車慢行或要点的情况下即可进行施工。在上扣軌卡和其螺栓时,工人只要蹲下弯下腰去,将手伸至枕木下端即可操作,不象文中所說的需要仰臥在路基上操作。如果工人操作熟練些,軌束的两端还是用軌卡比用
1. Buckle operation sequence; first tie spacing well, then on the inside buckle rail card. When the card on the track is one by one under the sleepers Ballast emptied, and then on, that is, a hollowed out one. Immediately after filling back ballast, it does not affect traffic safety. The rails on the inner side of the basic rail are flush with the rails on the outer side. Due to the inner buckle rail has all the good, it can be appropriate to dig more child hole. This kind of work, according to the provisions of article 14 of Yang-dae rules, do not need to slow down the train or points in the case of construction can be carried out.

If the workers operate more skillfully, the ends of the orbital beam are still used with a rail card
