自1976年我国颁布了“铁路道岔号数系列”国家标准(GB1246—76)后,使用中的道岔逐步趋向标准化。但由于历史原因,目前一些站场中许多道岔仍处于非标准状态。这些道岔不仅本身不易养护维修,而且其前后线路的线型也很紊乱,对运输安全影响极大。因此亟需对这些道岔进行改造。鉴于以往改造当中所走的弯路,我们认为,要想使整个改造顺利进行,首要任务是定位问题,也就是说需把道岔理论岔心及岔后曲线的交点,交角等测量出来,然后再进行改造。
Since 1976, China promulgated the “national railway turnout number series” (GB1246-76), the use of the turnout gradually standardized. However, due to historical reasons, at present, many switches in some stations are still in a non-standard state. These switches are not only difficult to maintain their own maintenance, and the line before and after the line is also very disorder, a great impact on transport safety. It is therefore imperative that these turnouts be retrofitted. In view of the detours we have taken in the past transformations, we think that in order to make the entire reconstruction proceed smoothly, the most important task is to locate the problem. That is to say, it is necessary to measure the intersections and angles of the turnout and turnout curves of the turnout theory before proceeding Transformation.
