巴基斯坦ML-1线罗赫里站升级改造方案研究

为解决既有ML-1线罗赫里站存在的正线技术标准较低、车站咽喉区布置凌乱、到发线长度不足和站场设备陈旧等问题,通过分析罗赫里站场条件,提出罗赫里站升级改造方案,提出将车站由直线站改造为曲线站,对既有罗赫里站站东咽喉外方反向曲线进行局部改造,延长夹直线作为咽喉区,延长了罗赫里站站坪长度。在此基础上,分析确定到发线规模、车站平面设计、横断面布置,增加旅客列车到发线、旅客站台等设施,对咽喉区进路布置进行优化,实现罗赫里站正线贯通布置。

A Study on the Upgrading Scheme of Rohri Station on Main Line-1 in Pakistan

To solve the problems in Rohri station of existing ML-1 line, such as low level of technical standard for the main line, poor layout of throat area, insufficient arrival-departure track length, and desolate station facilities, through analyzing the current situation of Rohri station, this study puts forward an upgrading plan, that the station is transformed from a straight station to a curve station. The cure outside the east throat of the station is partially transformed that the length of the station site is extended by extending the intermediate straight line as the throat area, and the platforms are also extended. On this basis, the quantity of arrival-departure tracks, plane layout and profile distribution are defined, tracks and platforms for passenger trains are added, route arrangement in the throat area is optimized, and the through operation in the station is achieved.
