客运专线两台夹四线站型纵向排水槽设置研究

Research on Arrangement of Longitudinal Drain Channel of Station with Two Platforms-rounding-four Lines on Passenger Dedicated Line

排水系统对于车站的运营作业、行车安全都有直接影响。在站场路基面排水系统中,纵向排水槽发挥着重要作用,纵向排水槽设计时需要同雨棚柱、接触网支柱等线间设备综合考虑、总体布置。文章针对客运专线中常见的两台夹四线布置图形,首先分析了纵向排水槽的分类及纵向排水槽设置的基本原则,着重研究两台夹四线布置图形6.5 m线间距纵向排水槽与接触网支柱等设备位置关系,提出了6.5 m线间距纵向排水槽结合接触网支柱布置的4个布置方案。从正线高速通过列车对排水槽的挤压破坏,保证路基稳定及排水畅通,利于工程实施等方面提出了客运专线两台夹四线布置图形纵向排水槽设计方案推荐意见。

Drainage system has a direct effect on the operation of the station and running safety of the train. The longitu- dinal drain channel plays a very important role in the drainage systems for subgrade surface of the yard. The longitudinal drain channel shall be arranged together with canopy column and OCS post in the design. Aiming at two-platform-roun- ding-four-line layout, this paper analyzes the classification of longitudinal drain channel and the basic arrangement prin- ciple of longitudinal drain channel, focuses on the study of the relation between longitudinal drain channel and OCS post under the condition of two-platform rounding-four-line layout with 6.5m distance between center of tracks and proposes four layout schemes. From extrusion damage of high-speed train on the main line to the drain channel main train speed, stability and smooth drainage of subgrade and work implementation convenience aspects, the recommendations on design scheme of longitudinal drain channel of two-Dlatform-roundinz-four-line lavout are ziven.
