Problems solved by technology

The depot is an important part of urban rail transit. The depot is a large-scale construction project, which requires a large investment and occupies a lot of land, and most of them are ground or semi-underground projects. a general trend, figure 1 What is shown is a typical way of rail connection. The disadvantage is that the station is far away from the field section because the access line and the main line need to be overpassed, so the development value of the field section cannot be effectively improved, and it is not conducive to the development of the superstructure of the field section. At the same time, it also affects the commuting convenience of the staff in the field section. Therefore, it is urgent to design a new urban rail transit layout type, combined with the comprehensive development of the field section, to solve the problems existing in the existing field section connection mode

Embodiment 1

[0019] The embodiment of the present invention discloses a layout structure in which the turnout and the field section are connected in parallel in urban rail transit. Considering that it is common for the connecting station to be an intermediate station, the planning and design are more flexible, so the connecting station is used as the intermediate station As an example to describe in detail, the layout is as follows figure 2 As shown, it includes the main line 1, the connecting station 2, the field section 3, the first turnout 4, the second turnout 5, the third turnout 6 and the pull-out line 7, the field section 3 and the connecting station 2 are closely arranged in parallel, and the pull-out line 7 is connected to the main line Line 1 is located at the same elevation, which is especially suitable for the situation where the connecting station 2 is a ground station and the field section 3 is on the ground; or the connecting station 2 is an underground station and the field...

Embodiment 2

[0021] When the connecting station 2 is a turn-back station, its layout structure is as follows image 3 As shown, the turnout line 8 is used to replace the switch one 4 in the first embodiment, and it can realize two-way departure under the condition that there is no hostile approach.

Embodiment 3

[0023] When the connecting station 2 is the terminal station, its layout structure is as follows Figure 4 Shown, compare with embodiment one, cancel the turnout one 4 in front of the station, set the switchback line 8 behind the station, its sending and receiving car is smoother.

Abstract

The invention discloses an arrangement structure adopting turnout and field segment parallel connection for urban rail transit. The arrangement structure is characterized by comprising a main line, aconnection station, a field segment, a shunting neck and turnouts; and the turnouts are arranged on the main line, the field segment is adjacent to the connection station, the field segment and the connection station are arranged in parallel, and the main line is connected with the turnouts through the shunting neck. A traditional connection form is optimized, under the condition that the designedreceiving-departure capacity is achieved, connection is achieved through the turnouts, the line inlet and outlet work amount is reduced, and the investment is reduced; and a station is close to the field segment, superstructure development of the field segment is facilitated, the utilization rate of land is increased, and meanwhile convenience is provided for field segment worker vehicle taking.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to an arrangement structure in which a turnout and a field section are connected in parallel in an urban rail transit. Background technique [0002] At present, the construction of urban rail transit in my country is developing rapidly. By the end of 2018, 30 cities have opened urban rail transit. The depot is an important part of urban rail transit. The depot is a large-scale construction project, which requires a large investment and occupies a lot of land, and most of them are ground or semi-underground projects. a general trend, figure 1 What is shown is a typical way of rail connection. The disadvantage is that the station is far away from the field section because the access line and the main line need to be overpassed, so the development value of the field section cannot be effectively improved, and it is not conducive to the development of the superst...
