用一个模型分析焊轨列车应用的条件

通过对秦皇岛 -沈阳客运专线 B2 7标段情况的分析得出铺轨基地存轨场地的面积是制约焊轨列车应用的一个重要因素。以预存长钢轨的数量为主要参数 ,利用焊轨列车在两个基地间工作的时间约束关系 ,建立起相应的模型 ,通过对其中其它参数的分析 ,得出应用焊轨列车所适宜的条件。在此基础上结合一次铺设跨区间无缝线路的工艺分析了焊轨工序与铺轨、大型机械养路工序的关系 ,提出了设备配套的建议和施工中应注意的一些问题。本文对设备选型、施工组织的编制及新工艺的采用有一定借鉴意义。

FROM A MODEL TO ANALYZE THE OPERATING CONDITION OF USING THE WELDING TRAIN

Analyze the condition of B27 bids works of Qinghuangdao-Shenyang dedicated passenger railway,conclude that the area of the yards to store the continuous welded rail is an important factor for welding train.Select the quantity of continuous welded rail deposited before laying in the yard as the optimized object,establish the model depending on the restrciting relationship of the time in which the welding train work in the two laying track teams,analyze the parameter to educe the condition of using the welding train.Then based on the technical flow of laying the continuous wedded rail,discuss the relationship of working procedure between the welding and others,and indicate some important parameter in selecting the equipment.This paper is useful for selecting the equipment,drawing the construction management plan,adopting new technics.
