小议道岔附带曲线养护维修方法热（The turnout curve method to maintain the heat） The turnout curve method to maintain the heat.Txt a really good friend and not together with endless topic, but together, if not speak will not feel embarrassed. When you look at other people, you are also the scenery in other peoples eyes. The road to tomorrow must remember the road that we walked yesterday and the road we are walking today. Turnout with curve is close to turnout, and it is reverse curve with guide curve. The direction and position of the attached curve is correct or not, which directly affects the safety and stability of the train, and has close relationship with the quality of the turnout, so it must be maintained and maintained with the switch. In production practice, we summed up the method of adjusting the alignment of the track, which can ensure the safety and stability of the train. In 1 concepts and relevant provisions of the supplementary curve In order to make the vehicle conversion track in the switch after femoral Cha is provided with a connecting curve, the curve direction and guide curve instead. General requirements: when the fork after two track parallel, and line spacing is less than 5.2m, so the connecting curve called turnout curve. Incidental curve should meet the following requirements: 1. Two parallel track line spacing is not greater than 5.2m; from the heel end to the starting point of the curve with straight length, generally not less than 7.5m, under difficult conditions shall not be less than 6m; the fringe curve radius shall not be less than the radius of the curved guide line turnout, 1.5 times but it is not greater than the radius of the guide curve (because the radius is the lead length; the curve with insufficient) can be set high, but high should be no more than 15mm, the slope rate of not more than 2 per thousand; the widening of gauge with the same general curve, by not more than 2 per thousand decline, line segment is short not more than 3 per thousan
