摘　　要：为解决特殊情况下需要在标准车站设置轨排井问题,通过设置临时三开道岔将轨排孔布置在中跨,轨排限界范围内混凝土结构柱需后浇,采用临时梁柱进行受力转化。本文介绍了如何进行三开道岔及轨排孔的布置、如何进行受力转换,并对受力转换的计算工况进行了分析。结果表明:采用临时设置三开道岔的形式可以解决在无配线车站设置轨排井的问题;采用临时钢立柱进行结构受力转换,结构安全可靠、经济合理。In order to solve the problem of setting track shaft in standard stations under special circumstances,track shaft is arranged in the middle span by setting temporary three-throw turnout.The concrete structural columns within the rail limits need to be post-cast,and the temporary beams and columns are used for force conversion.This article introduces how to carry out the layout of three-throw turnout and track shaft,how to carry out the force conversion,and analyzes the calculation condition of the force conversion.The results show that the problem of setting track shaft in the station without wiring can be solved by the temporary setting of three-throw turnouts.temporary steel column is used to carry on the structural force conversion,the structure is safe and reliable,economical and reasonable.
