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.
