Structure, including an island platform in curl trapezium structure, the width of an island platform is gradually increased from end of entering the station to outbound end, institute
The both sides for stating an island platform are respectively arranged with the first main track and the second main track, and first main track and the second main track are in an island platform
Station before connected by double crossover, the double crossover is constituted by the first single entry branch-cut bridge and the second single entry branch-cut bridge are intersecting, described
First main track, the second main track pass through respectively the first safety line, the second safety line behind the station of an island platform and are connected with circuit terminal,
First safety line is arranged in parallel with the second safety line；First safety line is by circular curve and the first single entry branch-cut bridge
Transition connects, and second safety line is connected by straightway with the second main track before an island platform station.
Further, an island platform is the song enclosed by first straight line, second straight line, the 3rd straight line and curve
Side trapezium structure, the first straight line and second straight line are arranged vertically with straightway, and the first straight line is leaned on second straight line
One end of nearly straightway is connected by the 3rd straight line, and the first straight line passes through curve with second straight line near one end of circular curve
Connection.
Further, the curve and circular curve are opening towards the circular arc line on the inside of an island platform.
Further, the radius >=1000m of the circular curve.
Yet further, the track switch at the double crossover adopts No. 9 track switches.
Further, it is smaller than an island platform station between the first main track and the second main track before an island platform station
Spacing between first main track and the second main track afterwards.
Compared with prior art, the utility model has the advantage that：
First, Design of platform of the present utility model is curl trapezium structure, will can lead in the line construction of existing station part
Cross a circular curve to connect the first safety line and double crossover, realize the quick change of distance between centers of tracks, shorten station length.
Second, taking double crossover to turn back before the utility model station, safety line is adopted after standing so that station total length is significantly
Reduce, reduce its difficulty of construction and risk.
Third, being smaller than an island platform between first main track and the second main track before an island platform station of the present utility model
Spacing after standing between the first main track and the second main track, before an island platform station of main track interval between the first main track and the second main track
Spacing may be controlled to minimum shield distance between centers of tracks, shorten the length of double crossover, improve the turning-back capacity at station.
