小车道岔测量特殊点

线形输入:道岔主线线形输入需要虚拟线形,已能够让小车自动选择到正确的导向轨。需要输入各个关键点的坐标和起始点的里程。

由于道岔尖轨藏尖区域的存在,在调整时3-8号岔枕不利用小车进行调整,而是利用弦测法,在1号和拉一条绳,利用绳来进行3-8号岔枕的精调。

在岔心的部分,也就是92号枕木的地方,在进行侧向测量的时候我们要切换导向轨,原因:在92-98号枕木处,小车双轮部分所在的钢轨存在变形,所以选择没有变形的钢轨那部分来控制轨道的精调,将92号和98号枕木调整好,此时切换导向轨,记录偏差信息,之后根据记录的92和98轨枕的数据进行92至98之间的轨枕的调整。

调整过程:1.主线平面高程调整到位,2.侧线高程到位,检核侧线平面,采集侧线数据3.搬回主线,进行主线平面和高程的调整和检核并进行数据的采集。调整要保证基本轨到位。
