The technical scheme adopted by the invention is as follows: the utility model provides an arrangement structure of parallel joint rail of switch and field section is adopted in urban rail transit, includes positive line, connects rail station, field section, draw-off line and switch, be equipped with the switch on the positive line, the field section is close to connect rail station, both parallel arrangement, positive line passes through the switch with the draw-off line and is connected.
Preferably, the first turnout is arranged on the positive line, the first turnout is positioned in front of the rail connecting station, the positive line is connected with the pull-out line through the second turnout, and the second turnout is positioned between the first turnout and the rail connecting station.
Preferably, a third switch is arranged between the positive line and the pulling-out line, and the third switch is positioned behind the rail receiving station.
Preferably, when the rail receiving station is a turn-back station, a turn-back line is used instead of the first switch.
Preferably, when the rail receiving station is a terminal station, a second switch and a third switch are arranged between the positive line and the traction line, the second switch is positioned before the rail receiving station, the third switch is positioned after the rail receiving station, a return line is adopted to replace the second switch between the positive line and the traction line, and the return line is positioned after the third switch.
Preferably, the positive line and the pull-out line are located at the same elevation.
And a turnout II and a turnout III are respectively arranged in front of and behind the track connecting station, a line close to the near field section side of the positive line is connected with a traction line, and the traction line is connected with a stock track in the field section, so that the track connecting of the station and the field section is realized. When the rail receiving station is a turning-back station, the turning-back line is used for replacing the turnout I, so that bidirectional departure can be realized under the condition of no hostile approach; when the rail receiving station is a terminal station, the first turnout before the station is canceled, and a turning-back line is arranged behind the station, so that the vehicle receiving and sending are smoother.
Compared with the prior art, the invention has the following beneficial effects: according to the invention, through optimizing the traditional rail connection form, under the condition of meeting the design capability of receiving and dispatching, the rail connection is realized through the turnout, so that the project amount of entering and exiting the line is reduced, and the investment is saved; the vehicle station is closer to the field section, so that the development of the upper cover property of the field section is facilitated, the utilization rate of the land is improved, and convenience is provided for the riding of field section staff.
