A、导言1、道岔加热的目的由于降雪是难以予测的,因此也很难专门安排劳力来有效地进行除雪作业。特别是在那些道岔比较集中的车站,清除道岔积雪更是一件十分困难的工作。道岔除雪是工务部门一个长期没有很好解决的问题。为在降雪天气中使道岔能正常开通使用,确保行车安全,必须寻求具备除雪作业时间短、设备及安装使用成本低廉等特点的其他有效的清除道岔积雪的方法。任何一种好的道岔除雪方法都应该使道岔区的尖轨和基本轨之间始终保持清洁无积雪状
A. INTRODUCTION 1. The purpose of turnout heating is difficult to predict due to snowfall, so it is also difficult to arrange labor to effectively carry out snow removal operations. Especially in those stations where the turnout is relatively concentrated, it is a very difficult task to clear the snow on the turnout. Turnout snow removal is a long-standing problem that has not been solved well by the public works department. In order to make the turnout normal use in snowy weather and ensure traffic safety, we must find other effective ways to clear the snow on the turnout with the features of short time for removing snow, low cost of equipment and installation. Any kind of good turnout snow removal method should make the switch between the sharp rail and the basic rail always clean and snow-free
