Abstract
The invention belongs to the technical field of bridge structures, and particularly relates to a closely arranged frame bridge structure of a high speed railway switch area. The bridge structure comprises a base plate located on a foundation, a side wall and a train walking roof. A plurality of closely arranged frames are formed by the base plate, the side wall and the train walking roof, the aperture of the frames which are perpendicular to the switch area ranges from 8 m to10-m, and a gap among the frames in the train driving direction is 2cm. The closely arranged frame bridge structure of the high speed railway switch area has the advantages that stress is clear, the structure is reasonable and the economy is good, requirements on a bridge longitudinal stiffness, a transverse stiffness and a displacement of the high speed railway switch are met, construction is convenient and fast, the construction process can move fast, service life of the structure is assured, traffic of a road under the frames can be also assured, the frames without interchange can be developed for business purposes, and that is to say, one bridge has three functions.
Description
Technical field
The invention belongs to bridge construction technical field, be specifically related to a kind of high-speed railway switch district solid matter frame bridge girder construction.
Background technology
At present, to establish the design and construction problem of bridge be the problem receiving much concern always high-speed railway switch district, particularly bottle-neck section.At railway station bottle-neck section, be traditionally arranged to be roadbed, there is no the precedent that bridge is set at bottle-neck section.But switch area (single group track switch), bridge is due to the requirement of high-speed railway seamless track switch to bridge construction, the general beam structure that adopts, whole group of track switch is all placed on a binding beam, structure relative complex, simultaneously because many group track switches can not be located on a binding beam simultaneously, track switch need be pulled open certain distance, cause bridge height, length to increase, in addition because switch area bridge design, constructional difficulties, construction quality are difficult to guarantee completely, and long construction period, often affects construction quality, duration of a project and construction investment.
Thereby for switch area, particularly bottle-neck section bridge, how to choose rational bridge construction form, to overcome the requirement of high-speed railway seamless track switch to bridge pier, beam rigidity, again can convenient construction, maintenance, improve the endurance quality of structure, guarantee the application life of structure, this is one of key technology of urgently studying and solving.
Summary of the invention
The object of the invention is for above-mentioned technical problem, provide a kind of stressed clear and definite, structure rationally, good economy performance, high-speed railway pier, beam strength, rigidity requirement can finely be met, convenient and quick construction, the high-speed railway switch district solid matter frame bridge girder construction that stencil design is simple, construction turnover is fast.
Technical scheme of the present invention is: high-speed railway switch district solid matter frame bridge girder construction comprises the base plate, abutment wall and the driving top board that are positioned on basis, described base plate, abutment wall and driving top board form some solid matter frameworks, described framework is 8-10m perpendicular to the aperture of switch area, between framework, is not more than 2cm along the gap that This train is bound for XXX.
Section with High Speed Switch of the present invention solid matter frame bridge girder construction, adopt the framework in 8-10m aperture to lay perpendicular to switch area main track, bullet train is sailed in frame plate top line, between framework, be 2cm along line direction gap, both met the requirement of high-speed switch to bridge vertical, horizontal rigidity, displacement, can take into account the current of road under framework simultaneously, also can double as business development without the framework of grade separation, be bridge three use simultaneously.Solid matter frame foundation can be selected open cut foundation or pile foundation according to geological conditions, and framework adopts construction with brackets.
The Section with High Speed Switch solid matter frame bridge girder construction that the present invention proposes, stressed clear and definite, structure rationally, good economy performance, can finely meet highway bridge to intensity, rigidity requirement, convenient and quick construction, construction turnover is fast, the application life of guaranteeing structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
High-speed railway switch district solid matter frame bridge girder construction as shown in Figure 1 comprises the base plate, abutment wall and the driving top board that are positioned on basis, base plate, abutment wall and driving top board form some solid matter frameworks, framework is 8-10m perpendicular to the aperture of switch area, between framework, is 2cm along the gap that This train is bound for XXX.
The present invention adopts the framework in 8-10m aperture to lay perpendicular to switch area main track, bullet train is sailed in frame plate top line, between framework, be 2cm along line direction gap, both met the requirement of high-speed switch to bridge vertical, horizontal rigidity, displacement, can take into account the current of road under framework simultaneously, also can double as business development without the framework of grade separation, be bridge three use simultaneously.Solid matter frame foundation can be selected open cut foundation or pile foundation according to geological conditions, and framework adopts construction with brackets.
General railway is before entering the station, because track becomes and makees even 12 lines of 6 lines from two-wire, due to high-speed railway seamless track switch to the beam seam of bridge construction the relativeness with track switch, bridge construction lateral displacement is no more than the harsh technical requirements of 1mm, switch area particularly bottle-neck section establish conventional bridge and cannot realize at all, therefore bottle-neck section is generally located on roadbed.But due to the impact of the fringe conditions such as line condition and grade separation, part station bottleneck must be arranged on bridge.Section with High Speed Switch of the present invention solid matter frame bridge girder construction, has solved this difficult problem well.Because the firm structure construction of conventional span is simple, short construction period, can reduce investment, can save the duration again, has good society and economic benefit.
Claims (1)
1. a high-speed railway switch district solid matter frame bridge girder construction, comprise the base plate, abutment wall and the driving top board that are positioned on basis, it is characterized in that: described base plate, abutment wall and driving top board form some solid matter frameworks, described framework is 8-10m perpendicular to the aperture of switch area, between framework, is not more than 2cm along the gap that This train is bound for XXX.
