Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 2 the orbit traffic overhead fusiformis station line construction of the present embodiment, including fusiformis platform 1, fusiformis station
1 both sides of platform are respectively arranged with the first up main track 2 and the second descending main track 3, and the first up main track 2 is included along fusiformis platform 1 one
The platform horizontal curve section 4 of side outer rim arrangement, the first horn mouth changeover portion 5 being arranged on before 1 station of fusiformis platform, and it is arranged on
The second horn mouth changeover portion 6 behind 1 station of fusiformis platform；The end of entering the station of platform horizontal curve section 4 is by the first horn mouth changeover portion 5
It is connected with first interval straightway 7, the outbound end of platform horizontal curve section 4 is straight with second interval by the second horn mouth changeover portion 6
Line segment 8 connects；Second descending main track 3 is symmetrical with regard to fusiformis platform 1 with the first up main track 2.This utility model passes through will
Design of platform is fusiformis platform 1, existing station part line construction can be improved to two by two parallel lines and symmetrical be in
The platform horizontal curve section 4 of arc-shaped, realizes the quick change of distance between centers of tracks by platform horizontal curve section 4, shortens horn mouth changeover portion
Length.
In above-mentioned technical proposal, the first horn mouth changeover portion 5 includes the first horizontal curve 9.1 set gradually along up direction
With the first intermediate straight line 10.1, the first horizontal curve 9.1 entered the station to hold and is connected by the first intermediate straight line 10.1 and platform horizontal curve section 4；
Second horn mouth changeover portion 6 includes the second intermediate straight line 10.2 and the second horizontal curve 9.2 set gradually along up direction, and second is flat
Curve 9.2 is connected with the outbound end of platform horizontal curve section 4 by the second intermediate straight line 10.2.Fusiformis station of the present utility model circuit
Structure shortens the length of horn mouth segment using fusiformis circuit, so as to reduce overpass twin shaft pier or transom pier quantity, reduces
Two ends bridge floor areas, and then construction investment is reduced, beautify landscape.Platform horizontal curve section 4 is opening towards on the inside of fusiformis platform 1
Circular arc line.First horizontal curve 9.1 and the second horizontal curve 9.2 are opening towards the circular arc line on the outside of fusiformis platform 1.Platform is put down
Curved section 4, the first horizontal curve 9.1, the sweep of the second horizontal curve 9.2 are 1000～3000m.First intermediate straight line, 10.1 He
The length of the second intermediate straight line 10.2 is not less than 20m.
Be illustrated in figure 3 the bridge pier arrangement schematic diagram of the present embodiment, main track along straightway be close to station when, with one group
Symmetrical opening is laterally spaced out as early as possible towards the first horizontal curve 9.1 on the outside of fusiformis platform 1, and ensures the first flat song of group
Line 9.1 does not invade platform area.When distance between centers of tracks is enlarged to be enough to envelope fusiformis platform 1, circuit is walked one section and is not shorter than the first of 20m
Intermediate straight line section 10.1 carries out transition, and into after platform area, circuit is changed to one group of symmetrical opening towards the station on the inside of fusiformis platform 1
Platform horizontal curve section 4, distance between centers of tracks is in the middle part of platform horizontal curve section 4, that is, platform centerline reaches maximum, afterwards two main tracks
Start to draw close.Circuit is just furthered after leaving platform the other end as early as possible, via 10.2 transition of the second intermediate straight line section, then along one group
Symmetrical opening advances towards the second horizontal curve 9.2 on the outside of fusiformis platform 1, shortens the length of horn mouth changeover portion as early as possible, returns
To the narrower second interval Line Segment 8 of distance between centers of tracks, circuit is integrally formed one centered on fusiformis platform 1, left and right, up and down
Symmetrical arrangement form.Compared with the bridge pier arrangement of Fig. 1 traditional orbit traffic overhead island station, the row of twin shaft pier 15
Number reduces three rows, the bell-mouthed contraction in length in one end about 90m, reduces construction investment.Additionally, two ends bridge floor area subtracts altogether
About 400m is lacked2, road daylighting is also improved while quantities is reduced.In addition, horn mouth changeover portion of the present utility model
One group of horizontal curve and intermediate straight line only being devised, one group of horizontal curve being reduced than traditional line construction, driving is more smoothed out, passenger
Take more comfortable.
The above, specific embodiment only of the present utility model, it is noted that any to be familiar with those skilled in the art
Member in the technical scope disclosed in this utility model, all should cover in this utility model by the change or replacement that can be readily occurred in
Protection domain within.
