Large passenger station structure for passenger special line

Abstract

The invention discloses a large passenger station structure for the passenger special line, comprising an upper yard, a lower yard, a throat area on upper yard, and a throat area on lower yard, wherein the upper yard and the throat area on upper yard are on the same plane; the lower yard and throat area on lower yard are on the same plane; and the throat area on upper yard and the throat area on lower yard are provided with a bidirectional interconnection line therebetween, through which the train can choose to enter the upper yard or enter the lower yard. The occupying area of the passenger station, and the distance of the throat areas can be reduced by using large passenger station structure for passenger special line, engineering investment cost is low, and the equipment is convenient to maintain.

Description

technical field [0001] The invention relates to a station structure of a large-scale passenger station on a passenger dedicated line. Background technique [0002] For high-speed railways, trains entering and leaving the station must meet the minimum tracking interval of 3 minutes, and the throat distance must be controlled within a relatively small range. The traditional large-scale passenger station structure of passenger dedicated line includes a single flat parking lot and throat areas for lines in all directions, and the throat area and flat parking areas are located on the same plane. If the traditional design method is still used, the distance of the throat area and the length of the yard will not be able to meet the driving requirements of high-speed railways, and the conflicts between trains in all directions will multiply, and the distance of the throat area will be the limiting factor for the passing capacity. Because when there are many directions of introductio...

AI Technical Summary

Problems solved by technology

If the traditional design method is still used, the distance of the throat area and the length of the yard will not be able to meet the driving requirements of high-speed railways, and the conflicts between train routes in all directions will increase exponentially, and the distance of the throat area will be the limiting factor for the passing capacity

Because when there are many directions of introduction and the scale of the depot is large, all traffic crossings are concentrated on the key nodes of the plane, which limits the passing capacity and operating efficiency of the depot, and the throat area needs to be designed with a complex turnout combination structure, resulting in the distance between the throat area and the length of the depot. long

At the same time, complex turnout combinations increase the complexity of the access interlocking system, making equipment maintenance difficult and safety indicators declining

At the same time, the distance between the throat area and the length of the station apron is too long, which will cause waste of land resources
