Rail transit train speed is fast simultaneously, freight volume is big, bridge structure is had high demands, qualitative problems of construction unavoidably. Normally run for guarantee rail transit train, generally require and build rail transit elevated bridge girder system system in city.And bridge system Unite using cast-in-place form of construction work more than each component, its holding time length, floor space are big, and quality is not easy to ensure.
It is therefore desirable to design one kind being capable of rapid construction and quality guaranteed rail transit elevated bridge girder system system.
Content of the invention
The purpose of the present invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of assembled rail transit elevated bridge beam Construction method.The present invention by adopting prefabricated components, site-assembled form of construction work, while ensure that component quality, Greatly reduce onsite application area occupied, and save the engineering time.
In order to reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of assembled rail transit elevated bridge beam construction method, mainly comprises the steps：
(1) prefabricated U beam, bent cap, pier stud and pile foundation；
(2) lift pile foundation at the scene, and pour cushion cap at pile foundation top, cushion cap bankets after the completion of pouring, subsequently with cushion cap On the basis of from bottom to top successively splicing pier stud and bent cap are installed；Wherein, a part for pier stud is located on the ground, and another part is located at ground Under；
(3) splicing erection support and contact net on bent cap；
(4) it is respectively provided with U beam in contact net both sides, U beam bottom is fixedly connected with bearing upper end.
It is preferred that after completing step (2), be exposed to the part setting rain of border of banketing in pier stud in above-mentioned method Water collection module, then carry out step (3).
While said structure scheme is provided, present invention also offers a kind of rail built based on above-mentioned construction method Road traffic overhead bridge structure, including：
Pile foundation, cushion cap, pier stud, bent cap, bearing and the U beam being fixedly connected sequentially from bottom to top；
Wherein, described U beam is two, is provided with contact net between two U beams, and the bottom of contact net is fixing with bent cap even Connect.
Preferably, described U beam has the thin-walled edge of a wing.
Preferably, described pier stud is circular configuration.
Preferably, the ground of described pier stud border is provided with rainwater-collecting module, rainwater-collecting module passes through pipeline and U The upper surface connection of beam.
Preferably, described bent cap is prestressed structure, is provided with 4 pairs of prestress holes.
Preferably, described rainwater-collecting module includes defecator and anti-overflow device, and defecator and anti-overflow device are permissible Identical with the structure in existing sponge city.
Preferably, described defecator is water-permeable brick.
Preferably, described anti-overflow device is water pipe.
Preferably, described water pipe connects with inside water-permeable brick, and water pipe is arcuate structure.
The invention has the beneficial effects as follows：
U beam, bent cap, pier stud, pile foundation, storm-water system and other each accessory precast assembly, form rail transit elevated bridge Girder system is united, and had both met the functional requirement of track traffic, and had taken into account the construction in sponge city, and had accelerated construction speed again, improve again The outward appearance of track traffic and surrounding is harmonious, and sound insulation and noise reduction reaches higher aesthetic effect, finally saved a large amount of soils, Reduce engineering cost, pollution-free, clean environment firendly, reach higher comprehensive benefit.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment 1：A kind of assembled rail transit elevated bridge beam construction method, its key step is as follows：
(1) prefabricated U beam 2, bent cap 3, pier stud 4 and pile foundation 6；
(2) lift pile foundation 6 at the scene, and pour cushion cap 5 at pile foundation 6 top, subsequently on the basis of cushion cap 5 from bottom to top according to Pier stud 4 and bent cap 3 are installed in secondary splicing；
Wherein, pile foundation 6 and cushion cap 5 are located at underground, pier stud 4 a part of located underground, another part is located on the ground.
(3) splicing erection support 7 and contact net 8 on bent cap 3；
(4) it is respectively provided with U beam in contact net 8 both sides, U beam bottom is connected with the splicing of bearing 7 upper end.
Embodiment 2：A kind of rail transit elevated bridge girder construction built based on the construction method described in embodiment 1, such as Shown in Fig. 1-5, including：
Pile foundation 6, cushion cap 5, pier stud 4, bent cap 3, bearing 7 and the U beam 2 being fixedly connected sequentially from bottom to top；
Wherein, described U beam 2 is two, is provided with contact net 8 between two U beams 2, and the bottom of contact net 8 is solid with bent cap 3 Fixed connection (for example splicing connects).U beam 2 can be standardized, industrialization construction, and adjusts profile chi according to real road situation Very little, span 28-35m, back width 5.17-5.57m changes.
Rail vehicle 1 can be advanced on U beam 2 along rail, and rail is installed in U beam 2.
Bent cap 3 profile is gem type, meets outward appearance coordination, environment harmony.
Described U beam has the thin-walled edge of a wing, has the function of sound insulation and noise reduction, saves sound barrier investment, final investment reduction, control Make this.Meanwhile, described pier stud 4 is circular configuration, using existing road green belt, Economization on land.
It is provided with rainwater-collecting module 9, rainwater-collecting module 9 passes through pipeline and U beam 2 on the ground of described pier stud 4 border Upper surface connection, the structure of rainwater-collecting module 9 can be chosen as and existing sponge urban structure identical filtration and infiltration brick.
Described bent cap 3 is prestressed structure, is provided with 4 pairs of prestress holes, can reduce structural volume, and weight reduces, stress Uniformly, higher endurance quality.
Described rainwater-collecting module 9 includes defecator and anti-overflow device, by PVC pipeline, rainwater is passed through letting out of U beam Water hole imports in collection device, the rainwater after collection, oozes road green belt by under filtering.As shown in fig. 6, defecator 9-1 Water-permeable brick can be chosen as, anti-overflow device 9-2 is chosen as the drain pipe that connect internal with water-permeable brick, and (drain pipe right-hand member is water inlet Mouthful), drain pipe has certain radian so that when meeting anxious rain, the water level in water-permeable brick rises until when not having drain pipe, water is just Drain pipe water conservancy diversion can be passed through.If water did not have drain pipe, the self performance of water-permeable brick can be relied on persistently water to be carried out Ooze under filtration.
In the present invention, assembled by each element precast, form rail transit elevated bridge girder system system, both meet track traffic Functional requirement, takes into account the construction in sponge city, accelerates construction speed again, improves construction quality track traffic and surrounding Outward appearance is harmonious, reaches higher aesthetic effect, can save a large amount of soils, reduce engineering cost, pollution-free, clean environment firendly, improve Comprehensive benefit.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention. Multiple modifications to embodiment will be apparent from for those skilled in the art, as defined herein general Principle can be realized without departing from the spirit or scope of the present invention in other embodiments, is not described in detail The part presenting with partial enlargement, is prior art, and here is not repeated.Therefore, the present invention is not intended to be limited to herein These shown embodiments, and it is to fit to the wide scope consistent with principles disclosed herein and feature.
