Further, the top barricade includes panel, counterfort and bottom plate, the panel one side fitting main platform,
Another side is bonded platform beams and the bridge pier of platform beams bottom, and the counterfort is arranged at the one side of panel attachment main platform,
Perpendicular to panel, bottom plate is arranged at panel and counterfort bottom and is bonded base respectively perpendicular to panel and counterfort, bottom plate both sides counterfort
This platform and the bridge pier of platform beams bottom.
Further, the top barricade is reinforced concrete structure.
Further, the panel width is 0.5-1.5m.
Further, the counterfort is along the longitudinally spaced setting of circuit, and the vertical cross-section of counterfort is up-narrow and down-wide trapezoidal
Or triangle, counterfort width are 0.5-0.6m.
Further, the base plate thickness is 1-2m.
Further, the pile body of the bottom pile foundation is reinforced concrete bored pile, and pile body is in double setting, stake
The stake footpath of body is 1-1.5m, and stake spacing is 2-4 times of stake footpath.
The utility model sets counterfort wall between main platform and platform beams, forms new road structure form,
Counterfort wall is by being rigidly connected as integral type structure, and physical dimension is small, simple structure, easy for construction, globality and stably
Property good, strong adaptability, can according to close to bridge pier justify pile foundation situation flexible modulation barricade size, can be widely applied to such
Railway station construction project, the roadbed filling thrust of main platform can be effectively avoided to have a negative impact platform beam bridge bridge pier,
With good economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1 main platform, 2 top barricades, 2.1 panels, 2.2 counterforts, 2.3 bottom plates, 3 bottom pile foundations, 3.1 pile bodies, 4
Platform beams, 5 bridge piers.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to be well understood
The utility model, but they do not form to the utility model and limited.
As shown in figure 1, the utility model include main platform 1, platform beams 4 and be arranged at main platform 1 and platform beams 4 it
Between counterfort wall, the counterfort wall includes top barricade 2 and bottom pile foundation 3, and top barricade 2 and bottom pile foundation 3 are logical
Cross and be rigidly connected into integral structure.The both sides of top barricade 2 are bonded main platform 1 and platform beams 4, the top of top barricade 2 respectively
Flushed with main platform 1 and platform beams 4, the bottom pile foundation 3 is supported in the bottom of top barricade 2.
The sides of platform beams (i.e. close to) sets PFF overall composites and oozes the complete of adrainage material and thick 0.2m after the barricade wall of top
Wall non-fine concrete block loaded filter.In actual applications, can according to be close to the distribution of existing building, foundation structure form and with
Its apart from size situations such as flexibly determine the size of top barricade, reserve 0.2 between top barricade and yard beam bridge bridge pier~
0.5cm expansion joints.
In such scheme, top barricade 2 includes panel 2.1, counterfort 2.2 and bottom plate 2.3, and top barricade wall is high by general 6~
10m.The one side of panel 2.1 fitting main platform 1, another side fitting platform beams 4 and the bridge pier 5 of platform beams bottom, panel 2.1
Top width is 0.5-1.5m, interior outside vertical；Counterfort 2.2 is arranged at the one side that panel 2.1 is bonded main platform, counterfort
2.2 perpendicular to panel 2.1, and counterfort 2.2 sets a section along circuit longitudinal direction at interval of 10m, and sets expansion joint, the vertical horizontal stroke of counterfort
Section is up-narrow and down-wide trapezoidal or triangle, and counterfort width is 0.5-0.6m；Bottom plate 2.3 is arranged at panel 2.1 and counterfort 2.2
Bottom and main platform and the bridge pier of platform beams bottom, base plate thickness are bonded respectively perpendicular to panel and counterfort, the both sides of bottom plate 2.3
For 1-2m.The high stressing conditions that can justify pile foundation close to bridge pier according to it with panel size of barricade wall flexibly select.
In such scheme, the pile body 3.1 of bottom pile foundation 3 is reinforced using C40 reinforced concrete bored piles, top barricade
The laying concrete leveling layers of bottom plate 2.3 times, the stake top of pile body 3.1, which is stretched into bottom plate, is not less than 10cm, and reinforcing bar is stretched into bottom plate
