Three-dimensional duplex transport system
Technical field
The present invention relates to a kind of traffic system and in particular to a kind of solid duplex transport system.
Background technology
At present, with the raising of China's expanding economy and living standards of the people, the quantity of motor vehicle gets more and more, and causes
The traffic conditions in city increasingly deteriorate, and traffic jam is increasingly serious, are not only unfavorable for the quick trip of resident, and cause big
The time of amount and energy resource consumption, air and noise pollution and traffic accident;The congestion of urban road and environmental pollution, it has also become
The key of restriction urban development;Greatly develop public transport especially track traffic, be the Main Means solving problem above.Existing
Some city rail dealings be mainly subway and light rail, its major defect be involve great expense, every kilometer of cost about several hundred million RMB,
Gigantic project, it is both needed to above and below the ground construct, construction period length, line typically require the time of 3~5 years, to ring during construction
Border impact is big, affect existing traffic and environment.
Existing rail on ground traffic generally requires the independent track of laying, because prosperity built by present overpass, real
Border is difficult to hew out independent space in urban planning for laying rail on ground traffic, therefore rail on ground traffic feasibility
Low.
Content of the invention
In view of this, the application provides a kind of solid duplex transport system, is changed by making on original overpass
Enter, using the remaining space with earth's surface upper pavement surface below existing overpass, develop a kind of Rail Transit System.
For solving above technical problem, the technical scheme that the present invention provides is a kind of solid duplex transport system, including ground
The some overhead bridge pier of setting on table road surface, the upper end of each overhead bridge pier is pier cap beam, and described pier cap beam is equipped with
It is characterised in that the lower section of described pier cap beam is embedded with connecting portion, described connecting portion underhung has track on overpass road surface
Beam, described track girder underhung is free rail train.
Preferably, described connecting portion includes two pieces of connecting plates be arrangeding in parallel, and the top half of described connecting plate is embedded in
Inside pier cap beam, the latter half of described connecting plate is exposed below pier cap beam.
Preferably, described connecting plate two side plane is uniformly placed with some WELDING STUDSs.
Preferably, described WELDING STUDS fusion weld is on described connecting plate.
Preferably, the diameter d of described WELDING STUDS meets following condition, 18mm≤d≤24mm.
Preferably, described track girder is provided with the rectangular beam of opening for bottom surface, and the both sides end face of described track girder is fixed on institute
State the lower end of connecting plate.
The application takes full advantage of the pier cap beam of overhead bridge pier upper end, using remaining to upper pavement surface below pier cap beam
Complementary space sets up sky rail traffic system.Lay suspension type rail in the pier cap beam lower surface of overhead bridge pier, can increase overhead
The space availability ratio of bridge, by rational bridge pier height layout, can ensure lorry and compact car meeting earth's surface road surface
While current, carrying out laying track makes sky rail train smoothly pass through.
Connecting portion includes fixing some WELDING STUDSs on connecting plate and connecting plate, and WELDING STUDS is evenly spaced in the two of connecting plate
Side, and be fixed on connecting plate by fusion weld or riveting, the application reaches the load-bearing mark of sky rail train by said structure
Accurate it is ensured that the operation safety of integrated model.
Be provided with track girder below connecting plate, described track girder internal sleeve equipped with track, by adjustable track beam vertical direction
The height gap of track can be adjusted with the displacement of horizontal direction, thus reaching the stable purpose of train operation.
Described sky rail train is streamlined compartment, has the advantages that good looking appearance.

Specific embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with the accompanying drawings and specifically real
The present invention is described in further detail to apply example.
As shown in figure 1, a kind of solid duplex transport system, the overpass arranging including earth's surface road surface 1 and thereon, described height
Build bridge and include some overhead bridge piers 2, the upper end of overhead bridge pier 2 is pier cap beam 3, is equipped with overhead bridge above pier cap beam 3
Face 4, for ensureing the load-carrying on overhead road surface and the load-bearing of empty rail train, described overpass road surface is 6 travelling for wagon train
Track, wherein every 3 tracks are collectively aligned.The lower section of pier cap beam 3 is embedded with connecting portion 5, is provided with below described connection portion 5
Track girder 6, track girder 6 underhung is free rail train 7.
Technique scheme takes full advantage of the remaining space between overhead bridge pier upper end pier cap beam and earth's surface road surface.?
The bridge pier pier cap beam lower surface laying suspension type rail of overhead transport bridge, can increase the space availability ratio of overpass, pass through
Rational bridge pier height layout, while can ensureing that lorry and dilly pass through meeting earth's surface road surface, is spread
If track ensures empty rail train passage.
As shown in figure 1, including a kind of preferred version 1 of overpass, the front view of described overpass is Π type, its load-bearing
Overhead bridge pier 2 includes each one around, is respectively placed in the left and right sides of the longitudinally central line in earth's surface road surface 1, a left side for overhead bridge pier 2
Right both sides all can be open to traffic, and described track girder 6 can be laid on the both sides of described overhead bridge pier 2 it is also possible to be laid on left and right two
The centre of individual overhead bridge pier 2.
As shown in Fig. 2 a kind of preferred version 2 of overpass, the front view of described overpass is T-shaped, its load-bearing overhead
Bridge pier 2 is placed on the longitudinally central line in earth's surface road surface 1, and described track girder 6 is laid on the both sides of described overhead bridge pier 2.
