Technical Field

The invention belongs to the technical field of urban rail transit, and particularly relates to an arrangement structure for connecting rails of turnouts and field sections in parallel in the urban rail transit.

Background

At present, urban rail transit construction in China develops rapidly, and 30 cities open urban rail transit by the end of 2018. The field section is an important component of urban rail transit, the field section belongs to large-scale construction engineering, the investment is large, the occupied area is large, most of the field section is ground or semi-underground engineering, along with the increasing shortage of urban land, the field section is developed into a large trend in a comprehensive integrated manner, a typical rail connecting mode is shown in a graph 1, and the defect is that an incoming line and a positive line need to be crossed, so a station is far away from the field section, the development value of the field section cannot be effectively improved, the field section is not beneficial to the development of upper cover properties, and meanwhile the commuting convenience of workers in the field section is also influenced.

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention provides an arrangement structure of connecting rails of turnouts and field sections in parallel, wherein the stations are closer to the field sections, the work load of incoming and outgoing lines is reduced, the comprehensive integrated development of the field sections is facilitated, the conflict between the occupation of land of the field sections and the urban planning can be relieved, and the convenience of commuting of field section workers on taking the subway can be fully exerted.

The technical scheme adopted by the invention is as follows: the utility model provides an arrangement structure that urban rail transit adopted switch and field section parallel connection rail, includes main line, rail station, field section, tractive line and switch, be equipped with the switch on the main line, the field section next-door neighbour rail station, both parallel arrangement, the main line passes through the switch with tractive line and is connected.

Preferably, a first turnout is arranged on the main line, the first turnout is positioned in front of the rail connecting station, the main line is connected with the traction line through a second turnout, and the second turnout is positioned between the first turnout and the rail connecting station.

preferably, a third turnout is arranged between the main line and the pulling-out line and is positioned behind the rail connecting station.

Preferably, when the rail connecting station is a switch-back station, a switch-back line is adopted to replace the first turnout.

Preferably, when the rail connecting station is a terminal station, a second turnout and a third turnout are arranged between the main line and the pulling-out line, the second turnout is located before the rail connecting station, the third turnout is located behind the rail connecting station, a turn-back line is adopted to replace the turnout between the main lines, and the turn-back line is located behind the third turnout.

Preferably, the positive line and the drawing line are located at the same elevation.

And a second turnout and a third turnout are respectively arranged in front of and behind the rail connecting station, a line on the side of the main line close to the field section is connected with a traction line, and the traction line is connected with a station track in the field section, so that the rail connecting of the station and the field section is realized. When the rail receiving station is a turn-back station, a turn-back line is used for replacing a turnout I, and bidirectional departure can be realized under the condition that no enemy approach exists; when the rail connecting station is a terminal station, a first turnout in front of the station is cancelled, and a return line is arranged behind the station, so that the receiving and dispatching of the railway station are smoother.

Compared with the prior art, the invention has the beneficial effects that: according to the invention, through optimizing the traditional rail connecting form, rail connection is realized through the turnout under the condition of meeting the design of the train receiving and dispatching capacity, the work amount of an outgoing line and an incoming line is reduced, and the investment is saved; the station is closer to the field section, so that the development of the property of the upper cover of the field section is facilitated, the utilization rate of the land is improved, and convenience is provided for field section workers to take the bus.
