Abstract
The present invention relates to a track transportation viaduct interval structure, and is characterized by that the transverse bridge section of the reinforced concrete pier column is made into the form of H type and Y type, and on the reinforced concrete pier column the precast prestressed concrete double small box beam is mounted. Said invention has the following technical features: its track transportation viaduct interval structure is more reasonable and beautiful, track beam is low in weight and the transverse section of the pier column is made into the form of upper-wide and lower-narrow curve, so that its floor area is small, and it is favorable for layout of pipeline and ground traffic management, etc.
Description
Technical field:
The present invention is the technical field of the related bridge engineering of civil engineering, is specifically related to a kind of interval structure pattern of orbit traffic overhead bridge.
Background technology:
The orbit traffic overhead bridge has the branch of two-wire and single line, at present, the bridge pier of the orbit traffic overhead bridge that China has implemented, in all linearly only post of shape or moulding of twin columns pier shaft of direction across bridge, distance is generally between 25～30m between pier, interval girder pattern has a single box single chamber (being called for short big case beam) or two single box single chambers (being called for short little case beam) prestress box beam, and the whole viaduct structure of composition shows as: the bridge pier moulding is more single, and direction across bridge has only post, twin columns; Girder is made the job practices that all adopts support cast-in-place, and construction period is bigger to the surrounding enviroment influence, and the duration is also longer.
Summary of the invention:
The object of the present invention is to provide the orbit traffic overhead bridge interval structure of a kind of view grace, easy construction.
To achieve these goals, technical scheme of the present invention is: a kind of orbit traffic overhead bridge interval structure, it mainly comprises foundation platform, be cast in the steel bar concrete pier stud on the foundation platform and be arranged on prestress concrete prefabricated case beam on the steel bar concrete pier stud, it is characterized in that: the direction across bridge of steel bar concrete pier stud is H type, Y type, is provided with precast prestressed concrete double small case beam on the steel bar concrete pier stud.
The orbit traffic overhead bridge interval structure that above-mentioned feature of the present invention constitutes has following technical characterstic, one, little case beam of track and direction across bridge are the bridge pier of H type, Y type, and pier stud is the abduction shaped form, and the orbit traffic overhead bridge interval structure that is constituted is more coordinated rationally, novel and beautiful; The rail beam that its two, two single box single chamber prestress concrete Small Precast Box beams are formed, its single little case beam in light weight makes rail beam prefabrication and lifting form of construction work become feasible, thereby accelerated construction progress, and the duration shortens, and has reduced the influence to environment and traffic; Its three, bridge pier pier stud direction across bridge is shaped form wide at the top and narrow at the bottom, its occupation of land is less, is beneficial to the laying and the traffic above-ground tissue of pipeline; Its four, adapt to the railway line spacing and change bridge pier and have firm structure system of one's own and can satisfy the every technical requirements of track traffic fully; Its five, it more can adapt to the development and the variation of orbit traffic overhead bridge, further satisfies view, construction, economic demand, reaches novel unique, the construction purpose of civilization fast.
Description of drawings:
Fig. 1 is orbit traffic overhead bridge interval structure cross section (two-wire) schematic diagram that the present invention forms
Fig. 2 is a lateral view shown in Figure 1
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
The present invention mainly comprises the basis, this basis is made up of steel bar concrete cushion cap 5, stake 6, be cast in the steel bar concrete pier stud on the foundation platform and be arranged on prestress concrete prefabricated case beam on the steel bar concrete pier stud, it is characterized in that: the direction across bridge of steel bar concrete pier stud 1 is H type, Y type, is provided with precast prestressed concrete double small case beam 2 on the steel bar concrete pier stud.The upper pillar stand that the bridge pier direction across bridge is H type, Y type pier stud in the enforcement is the abduction shaped form, and lower pillar stand is vertical shape or abduction shaped form, and its inclination angle is controlled at 〉=70 degree; Precast prestressed concrete double small case beam is that two little case beams of single box single chamber are formed rail beam 3, little case beam is the prefabrication and lifting construction, two little case beams are fused by Cast-in-place concrete, bridge pier pier shaft direction across bridge is shaped form wide at the top and narrow at the bottom, its occupation of land is less, and the laying and the traffic above-ground pseudometaplasia railway line spacing that are beneficial to pipeline change, and are provided with bearing on the pier shaft of bridge pier, rail beam is two single box single chamber prestress concrete Small Precast Box beams, and places bridge pier pier shaft bearing.
Technical characterstic of the present invention reduces:
1. interval structure pattern, bridge pier pier stud direction across bridge is H type, Y type, and the steel bar concrete pier stud is the abduction shaped form.
2. interval structure pattern, rail beam is two single box single chamber prestress concrete Small Precast Box beams, and places on the bridge pier pier shaft bearing 4.
3. rail beam is the prestress concrete prefabricated units, and striding the footpath scope of application is 20～35m.
4. the basis is made up of steel bar concrete cushion cap, stake, and pile foundation has reinforcing bar concrete square pile, PHC pile tube, bored pile.
The orbit traffic overhead bridge interval structure pattern of present embodiment is made up of shaped form H type steel bar concrete pier stud 1 and basis, prestress concrete pre-track beam 3 and bearing 4.
It is bridge pier control primary structure member that the pier shaft upper pillar stand is the abduction shaped form, and the angle of its inclination directly influences or control the force-bearing situation of bridge pier, is considering to take into account its facade moulding in stressed (controlling its tensile stress).Its inclination angle promptly is controlled at the angle of level 〉=70 degree.
Job practices of the present invention is fast convenient, and in the pier stud construction, it is prefabricated to carry out the prestress concrete rail beam, after the pier stud concrete reaches intensity, carry out rail beam and start shipment lifting, behind the hoisted in position, finally finish cast-in-place section concrete of rail beam and build, constitute whole rail traffic viaduct interval structure.
