    四、线路维修基本作业                                                               
    线路维修基本作业包括:起道、捣固、改道、拨道、垫板、整正与调整轨缝、修理轨底坡、方向轨枕、轨枕及零件、清筛道床、整治冻害等。                                                               
    (一)线路起道作业:                                                               
    起道一般由三人互相配合作业,一人看道、量水平,一人抬道,另一人打塞。每次起道超度应该根据列车间隔时间确定,要求在列车到来前能完成起道地段的捣固和顺撬。                                                                                                                                   
    1.划出轻重捣、低接头、拱腰、空吊板等处所,用约定的符号表示。                                                               
    2.打浮离道钉或拧紧扣件螺栓,消除空吊板。                                                               
    3.起道应使用专用撬棍做把手,并不得以起道机蹬钢轨或枕木头。                                                               
    4.起道量的确定应考虑先有石碴量,要防止盲目起高道而造成缺碴                                                               
    5.放置起道机。拿起道机的人要密切注视看道者的指挥,正确地放置起道机,动作要敏捷。全起全捣时,起道机一般在接头中间放置一次,两端距接头8根轨枕处各放置一次,并顺次向前;重起全捣或重起重捣时,陡坑在坑底处放置一次,漫坑则要放置2-3次。起道机必须放平放稳,直线放在钢轨里口,曲线上股放在外口,曲线下股放在里口;                                                               
    接头中间这孔。不要放在绝缘接头的轨缝中。                                                               
    6.打塞(砸撬)。当轨道起到要求的高度后,打塞者在钢轨外侧轨底处,将道碴串实,禁止打顶门塞。确保撤出起道机后轨道不回落。在混凝土地段起道时,打塞者应协助拿起道机抬起线路,并将起道机两侧轨枕底道碴串实。                                                               
    7.技术要求:                                                               
    (1)起道用的道尺、水平板、高度板,应经常校对,保证精确无误。                                                               
    (2)根据《线路维修规则》的规定,每次起道高度不得超过40mm,超过时需慢得施工,100mm以上时应设停车信号防护。                                                               
    (3)起道者必须随时注意看道者的手势或口令,起道高低要适当。为防止回落,预留的下沉量一般不得超过4mm。                                                               
    (4)起道顺坡长度,作业时不应少于起道高度的200倍,收工时不应少于起道高度的400倍。
