System and method for realizing turnaround in front of urban rail transit stations

Abstract

The invention discloses a system and method for realizing station-front turning-back of a urban rail transit. The system comprises an island platform, wherein an upper direction rail main line and a lower direction rail main line are arranged at the two sides of the island platform; in front of the island platform, a first intersecting point on the upper direction rail main line is provided with a translation line connected with a second intersecting point on the lower direction rail main line; and a third intersecting point on the upper direction rail main line is provided with a connecting line connected with a fourth intersecting point on the lower direction rail main line. As the system has two independent turning-back access lines, trains can alternately use the two access lines for turning back without being interfered so as to improve the station turning-back capacity.

Description

Technical field [0001] The present invention relates to the technical field of urban rail transit. More specifically, the present invention relates to a system and method for realizing turning back in front of an urban rail transit station. Background technique [0002] At present, my country has become the country with the fastest development of urban rail transit in the world. However, in actual operation, many urban rail transit lines have the situation that the early passenger flow arrives in the near future, the long-term passenger flow arrives recently, and the passengers cannot get on the train in the morning and evening peak. In view of this, the newly-built rail transit lines in major cities have chosen Type A cars with larger capacity. Rail transit has many advantages such as speed, convenience, punctuality, comfort, etc., which makes the rapid transfer of ground buses to rail transit. At the same time, the intensity of real estate development along the rail transit is...

AI Technical Summary

Problems solved by technology

However, in the actual system design process, some more complicated situations are often encountered, such as the influence and limitation of factors such as passenger flow section, station scale, building structure form, engineering geological conditions, and the increase in the length of the train formation prolongs the turnaround of the train. Walking distance, all these factors will have a negative impact on the turn-back capability, making it difficult to meet the needs of turn-back capability with simple turn-back before or after the stop, or the reserve of turn-back capacity is insufficient

In addition, compared with the minimum tracking interval, the turn-back capability is the biggest bottleneck that really restricts the improvement of line transportation capacity
