Rail holding type electromagnetic suspension track traffic box girder

Abstract

The invention discloses a rail holding type electromagnetic suspension track traffic box girder. The box girder comprises a top plate, a bottom plate and a web plate located between the top plate and the bottom plate. The top plate, the bottom plate and the web plate are of a reinforced concrete structure formed by overall pouring, an outer protrusion and a boss allowing an electromagnetic suspension track to be mounted are arranged at the two side ends of the top plate, and wing plates which stretch out towards the upper inclined portion are arranged on the two sides of the bottom plate. A mounting platform is arranged at the top ends of the wing plates, the mounting platform is of a boss structure which stretches out towards the outer side in the horizontal direction, can be used for arranging a pedestrian footpath and an evacuation exit and also can be used for arranging track traffic accessory facilities such as an inspection gallery, guardrails, a noise barrier, a signal machine and an AP antenna, and daily maintenance of a line is facilitated. The wing plates of the box girder shield on-bridge tracks, trackside equipment, cables and the like, and the landscape effect is obviously improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and specifically designs a rail-holding type maglev rail transit box girder. Background technique [0002] There are mainly two types of girder type schemes for existing maglev rail transit and straddle monorail transit: single-line box girder scheme and double-line box girder scheme. [0003] The single-line box girder scheme, in the unique "rail-holding" operation mode of maglev rail transit and straddle monorail transportation, the single-line box girder that meets the vehicle limit requirements is the most economical beam type scheme. The girder structure of this scheme is the vehicle running track, and the double-track section adopts the juxtaposition of two single-track box girders. This beam type is used in the maglev and straddle monorail traffic track beams that have been built in China. figure 1 is the cross-sectional view of the track beam of Shanghai High-speed Maglev Tra...

AI Technical Summary

Problems solved by technology

[0007] To sum up, among the existing girder schemes of maglev rail transit and straddle monorail transit, the single-track box girder is convenient for construction and good in economy, but has disadvantages such as daily maintenance of the line, difficulties in rescue and escape, and poor landscape effects; Although the cable box girder meets the needs of cable laying and maintenance, rescue and escape channel setting, and the daily maintenance of the line is relatively simple, there are problems such as difficult construction, long construction period and poor economy
