A turn-back island-style station layout structure in front of urban rail transit stations

Abstract

The invention provides a station-front turning-back island-type station arrangement structure of urban rail transit. A first main line and a second main line are arranged on the two sides of an island-type platform correspondingly; a first curve is connected with the first main line and a scissors crossover, and a second curve is connected with the second main line and the scissors crossover; anda first interval main line and a second interval main line are connected through the scissors crossover. According to the station-front turning-back island-type station arrangement structure of the urban rail transit, the total length of a station is shortened effectively, and the project scale is reduced; the travelling distance of train turning-back operation is shortened, and the efficiency ofthe train turning-back operation is improved; and applicability is wide, flexibility is high, arrangement structures of overhead stations and underground stations can be met, and the island-type station arrangement structure is suitable for the multiple platform widths.

Description

technical field [0001] The invention relates to the technical field of urban rail transit line design, and more particularly, relates to an arrangement structure of an island-type station with a switchback in front of an urban rail transit station. Background technique [0002] In recent years, my country's economy has developed rapidly and the urbanization process has gradually accelerated. As a country with a large population density and relatively scarce resources, traffic congestion has become a serious problem faced by cities. Therefore, in order to ensure the healthy and stable development of cities, the promotion of public transportation has become the general trend. Urban rail transit has won unanimous praise from the people for its large capacity, comfort and speed, and many cities are vigorously developing urban rail transit. [0003] In the design of rail transit, according to the traffic organization, the train turn-back line should be set at the starting and end...

AI Technical Summary

Problems solved by technology

[0003] In the design of rail transit, according to the traffic organization, the train return line should be set at the starting and ending stations and the intermediate return station to meet the requirements of the train return operation. After the station is set up, the scale of the station will inevitably increase, and the project investment will increase accordingly.

[0004] In the prior art, the turn-back station in front of the rail transit station is connected by a crossover line between the main lines in front of the station, such as figure 1 As shown, the distance between the main line 7 of the first section and the main line 8 of the second section where the crossover line 6 is located is the same as the distance between the first main line 1 and the second main line 2 on both sides of the platform, and the crossover line 6 The length is greatly affected by the distance between the first main line 1 and the second main line 2, resulting in longer stations and larger project scales
