Arrangement structure of stud-end type station of urban rail transit

Abstract

The invention discloses an arrangement structure of a stud-end type station of urban rail transit. The arrangement structure comprises an island platform with a curvilinear trapezoid structure, wherein a first main line and a second main line are arranged on two sides of the island platform respectively and are connected in front of the island platform through a double crossover, the double crossover is formed through intersection of a first single crossover and a second single crossover, the first main line and the second main line are connected with a line end point through a first safety line and a second safety line respectively behind the island platform, and the first safety line and the second safety line are mutually parallel; the first safety line is in transitional connection with the first single crossover through a circular curve, and the second safety line is connected with the second main line in front of the island platform through a straight line segment. The platform is designed into the curvilinear trapezoid structure, the first safety line and the double crossover are connected through the circular curve, so that rapid change of a distance between the lines is realized, and the station length is reduced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit lines, in particular to an arrangement structure of end-type stations of urban rail transit. 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 addition to meeting the functions of the station, urban rail transit end-type stations also need to meet the requirements of vehicle turn-back. The layout of the turn-back line should be determin...

Problems solved by technology

[0004] However, in the actual design process, some more complicated situations will be encountered, such as the influence and restriction of factors such as surrounding buildings, road width, engineering geological conditions, and transfer types with other lines, which will cause adverse effects on the layout of the station. influences

Underground stations generally adopt open-cut construction, and the excavation range of the end-type station that turns back after the station is relatively large. However, many areas of cities in our country often face problems such as narrow roads, dense buildings, and complicated flow of people and vehicles. If large-scale In open-cut construction, it will face problems such as difficulties in dispersing the surrounding traffic organization, a large amount of demolition, increased construction difficulty and excessive construction risks. In some areas with more complicated conditions, it is even impossible to set up stations that turn back after the station.
