Description
Technical field
The utility model relates to bridge construction technical field, and specific design one embraces rail magnetic levitation track traffic bridge.
Background technology
Existing magnetic levitation track traffic and straddle-seat type single traffic rail beam beam type mainly contain two kinds: single line case beam scheme and double line box girder scheme.
Single line case beam scheme, take in unique " embracing rail " method of operation at magnetic levitation track traffic and cross-saddle single-track traffic etc., the single line case beam meeting vehicle gauge requirement is most economical beam type.Program beam structure is travelled by vehicle track, and the juxtaposed mode process of two panels single line case beam is taked in two-wire location, and domestic built magnetic is floating all adopts this beam type with straddle-seat type single traffic rail beam.Fig. 1 is Shanghai high speed Maglev rail beam sectional view, Tu2Shi Chongqing City straddle-seat type single traffic rail beam sectional view, and Fig. 3 is certain medium-and low-speed maglev traffic experiment line rail beam sectional view." embrace rail " because of vehicle to run, single line box girder bridge can utilize limited space, case top surface of the beam can only meet track and arrange needs, power rail, cable can be hung on outward case beam sides and bottom surface, passage when circuit regular maintenance and vehicle generation accident needed for passenger's emergency evacuation cannot be arranged, and the ancillary facility such as railing, noise barrier is also installed nowhere.For meeting circuit regular maintenance and rescue run needs, Chongqing City is when building Article 2 cross-saddle single-track traffic line-Rail Transit Line 3, complete the cable laying along circuit by rail beam side erection girder steel, on it, grid coverage steel plate forms maintenance and rescue run passage.This processing mode solves the access issues of daily line upkeep and passenger's emergency evacuation, but investment increases more, and girder steel later maintenance workload is also larger.Formula track traffic belongs to urban track traffic category " to embrace rail ", and require higher to the view of bridge, the domestic single line case beam taked all not can solve the Landscape of elevated bridge at present.
Double line box girder scheme beam structure is divided into two-layer, and lower floor's double line box girder is main part of the force, it is arranged the little support rail beam of twice, as the track that vehicle is out of shape, forms " beam upper beam " structure.As shown in Fig. 4 double line box girder sectional view, double line box girder bridge floor is wider, and sufficient space can be provided to carry out the setting of cable laying and maintenance, rescue run passage.But its shortcoming is also more outstanding, first, support rail beam is as travelled by vehicle track, and participation structure is not stressed substantially, and waste of material is less economical; Secondly, support rail beam need after double line box girder has been constructed cast-in-place construction, operation is loaded down with trivial details, and the duration is longer; 3rd, the textural association height of double line box girder and support rail beam is higher, and landscape effect is also bad.
The aspects such as collateral security construction quality, reduction of erection time, reduction construction investment are considered, the general location of elevated bridge adopts simply supported beam, fabrication and erection method to construct usually.
Magnetic levitation track traffic and cross-saddle single-track traffic all belong to urban track traffic, and circuit exists the feature that sharp radius curve is many, continuous beam Controlling vertex is many.Double line box girder beam field is prefabricated complete after, utilize the bridge of having constructed as transport channel, be transported to bridge location rear frame member with Beam transportation vehicle in place.The double line box girder scale of construction is comparatively large, and beam body transportation rack device is by sharp radius curve difficulty, and Controlling vertex also may hinder beam transporting passage through, causes Bridge Erector repeatedly transition, and investment significantly increases, and affects the duration.The single line case beam scale of construction is less, and beam body can ground transport, adopts the methods such as automobile crane, crawler crane, gantry crane to set a roof beam in place, and beam body transport erection is more flexible, and constructing aims more easily realizes.
In sum, in current magnetic levitation track traffic and the existing beam type of cross-saddle single-track traffic, single line box girder construction is convenient, good economy performance, but there is the shortcomings such as circuit regular maintenance and rescue run difficulty, landscape effect be poor; Although double line box girder meets the needs of cable laying and maintenance, rescue run channel setting, circuit regular maintenance is fairly simple, there is constructional difficulties, duration longer, less economical problem.
So, find a kind of pattern rationally, easy construction, economy is good, landscape effect is good " embracing rail " formula track traffic track beam structure tool be of great significance.
