Rapid shuttle single-tunnel double-decker track subway

Abstract

The invention discloses a rapid shuttle single-tunnel double-decker subway, a train running space configured by shuttle tunnels with a upper and a lower track and double stereo train stations, the subway herein requiring less land occupation and digging work load. According to the subway herein, lines are composed of express lines, train stations, and launching lines, allowing separation of trains which are running from trains which stop for allowing passengers to get on and get off. The subway herein allows changes to train tracking operation, launches of express shuttles as needed, reduction of stops, and increasing of train operating density and running velocity. The subway herein also allows using train hooks to conduct rapid train re-arrangements, increasing train re-arrangements in peak time, operating non-stop trains or limited-stops trains so as to increase passenger capacity. The subway herein further allows decreasing of train re-arrangements in normal time or low peak time in a manner whereby trains stop at each and every train station so as to reduce operation cost. According to the subway herein, a recessed bottom train frame structure is adopted in the train for reducing train height and center of gravity, and tunnel diameter is decreased. By planning of different passenger capacities, selecting different train re-arrangements, and adopting various running patterns based on passenger flow time frames, the subway herein obtains an improved cascade-type passenger capacity ranging from 10,000 to more than 90,000 per hour for a single direction. The rapid shuttle single-tunnel double-decker subway of the invention adjusts to capacity demands in megacities, and can reduce starting-point requirements for building subways, like size of city passenger flow and population.

Description

technical field

[0001] This case involves a kind of subway, which aims to change the tracking operation mode, reduce stops, run fast in the section, and increase the travel speed. Specifically, it is a single-hole double-deck lane subway in the fast section. Background technique

[0002] Urban subway passenger transport has three notable features: First, the distance between stations is short, ranging from 800 meters to 1500 meters, resulting in a large number of stops. The second is that the morning and evening passenger flow peaks are large and the duration is short. According to the official passenger flow statistics of the Beijing Metro, the passenger flow during the morning and evening peak periods on normal working days is double-convex, and 48% of the passenger flow throughout the day is concentrated within four hours of the morning and evening peaks (Table 1 The passenger flow during the morning and evening peak hours accounts for the proportion of the whole day); th...
