宝中增建二线引入中卫铁路枢纽方案研究

Research on the scheme of introducing Baozhong Second Line into Zhongwei Railway Hub

在中卫铁路枢纽现状分析和规划线路研究的基础上,为实现宁夏自治区“五市同城化”动力集中型列车直通的功能需求,结合近、远期运量及相关线路建设时机,统筹考虑中卫枢纽点线能力协调,研究宝中二线引入中卫铁路枢纽方案。将宝中线、太中银线以及包兰线作为整体进行综合研究,分析宝中增建二线利用既有通道和新建通道两类四个方案,推荐运输组织顺畅、投资较省的利用太中银铁路黄河桥方案;围绕宝中增建二线的运输组织,研究了双线运输及双单线运输方式,推荐运输能力适应性强、运输组织顺畅的新建线路按下行方向运行方案,最后对潘营至余丁联络线于既有太中银黄河桥出岔及施工方案进行研究,提出可实施性强、投资节省的建设方案。结合工程建设条件,对新建线路从通道选择、运输组织、工程技术等方面进行多方案研究比选,为整合枢纽内线路设备资源、优化枢纽布局及运输组织提供参考。

Based on the analysis of the current situation of the Zhongwei Railway Hub and the study of planned routes,in order to meet the functional requirements of the“Integration of Five Cities into One City”power concentrated train direct connection in Ningxia Autonomous Region,combined with the short-term and long-term transportation volume and relevant line construction opportunities,the coordination of the Zhongwei Hub point line capacity is comprehensively considered,and the Baozhong Second Line is introduced into the Zhongwei Railway Hub scheme.This article conducts a comprehensive study on the Baozhong Middle Line,Taichung Yinchuan Railway,and Baolan Line as a whole.Analyze four plans for the construction of a second line in Baozhong,utilizing existing channels and new channels,and recommend a plan for utilizing the Yellow River Bridge on the Taichung Yinchuan Railway with smooth transportation organization and relatively low investment;Focusing on the organization of the second line transportation in Baozhong,we have studied the double line transportation and double single line transportation methods,and recommended a new line operation plan with strong adaptability and smooth transportation organization in the downward direction.Finally,a study was conducted on the bifurcation and construction plan of the Panying Yuding connecting line at the existing Taizhongyin Yellow River Bridge,and a construction plan with strong feasibility and investment savings was proposed.This article combines the conditions of engineering construction to conduct a comparative study of multiple schemes for the construction of new lines from the aspects of channel selection,transportation organization,engineering technology,etc.,providing reference for integrating line equipment resources within the hub,optimizing hub layout and transportation organization.
