摘要
遂溪站是湛江枢纽内的中间站,在新建合湛线工程中车站增建茂名方向疏解联络线,全站按"四进—四出"上下行两场进行改扩建。根据车站改扩建方案特点及车站既有特征,结合运输生产的需求,研究制定了基于信号过渡模式的站改施工过渡方案。文章详细分析了既有设备改建难点以及施工过渡的原则和方法,分析比较了信号采用不同过渡模式对过渡工期、施工组织、工程费用及运输组织产生的影响。通过研究得出结论,信号采用"新站房-新站型"的过渡模式较为合理,能有效节省过渡工程费用,降低运输干扰。最后,基于该信号过渡模式,统筹站前、站后各专业制定出合理的全站施工过渡方案和具体施工过渡步骤,确保车站改扩建工程能顺利有效的实施。
Suixi Station is an intermediate one located in Zhanjiang railway terminal. For the project of new Hepu-Zhan-jiang line, it is planned to build an additional untwining connecting line in Maoming direction in the station. The station will be expanded according to“four-entrance—four-departure” up yard and down yard. According to the characteristics of reconstruction scheme and existing features of the station and in combination with the demand of transportation produc-tion, the construction transitional scheme based on signal transition model is determined. The paper analyzes in detail the reconstruction difficulties of the existing equipment, principles and methods of the construction transition, and compares the influence of the signal with different transition models on the transition period, construction organization, project cost and transport organization. Study result shows that signal the transition model of＂new station building-new station type＂is more reasonable and can effectively save the transition engineering costs and reduce the interference of transportation. Finally, based on the signal transition mode, a reasonable detailed transition program and specific construction transi-tional step shall be developed to ensure the reconstruction and expansion of the station can be implemented successfully.
