Problems solved by technology
The other is the girder-on-girder scheme, that is, the rail-supporting beam is arranged on the top surface of the traditional box girder. This scheme solves the problem of difficulty in setting up auxiliary facilities and rescue and evacuation platforms, but the hoisting weight of the box girder is large during construction, and the rail-bearing The beams are exposed on the top surface, the overall building height is high, and the landscape effect is not good

Embodiment 2
[0047] Example two such as Image 6 As shown, the difference from the first embodiment is that the outer railing 12 is provided with a sound barrier 14, which can meet the requirements for areas with high noise levels.
Embodiment 3
[0048] Embodiment three such as Figure 7 As shown, the difference from Embodiment 1 and Embodiment 2 is that the two sides of the top plate 4 of the rail support beam are provided with convex bosses.
Embodiment 4
[0049] Embodiment four such as Figure 8 As shown, the difference with Embodiment 1 and Embodiment 2 is that the rail platform 10 and the rail row 11 are canceled on the rail beam top plate 4, but the maglev train is arranged on both sides of the rail beam top plate. Suspended, guided and supported (sliding) track functional parts 18, this structure can meet the operation requirements of high-speed maglev vehicles.

The invention discloses a magnetic suspension rail traffic double-line simply supported beam which is a combined body of a pre-stressed concrete trough-type beam and a reinforced concrete rail supporting beam. The trough-type beam comprises a bottom plate, an arc-shaped web and a T-shaped flange plate, two sides of the arc-shaped web project outwards, the T-shaped flange plate is arranged at the top of the arc-shaped web, a strong current cable, a weak current cable, a leaky coaxial cable, a cable support and the like are arranged on the inner side of the arc-shaped web, the flange plate at the top of the web serves as an evacuation channel and a maintenance channel and is provided with magnetic suspension rail traffic subsidiary facilities such as a handrail, a signal machine, a sound barrier and an AP (access point) antenna, and double-line rail supporting beams are arranged in the trough-type beam and share a bottom plate of the trough-type beam. The rail supporting beams comprise atop plate and two webs, and the webs are fixedly connected with the bottom plate of the trough-type beam. The simply supported beam has the advantages that structural strength and structural stiffness are met, and spatial layout function requirements on a bridge and attractive, economic and environment-friendly requirements are met.
Description
technical field [0001] The invention relates to the field of track support structures for maglev rail transit, in particular to a double-line simply supported beam for maglev rail transit. Background technique [0002] In the existing maglev rail transit track support structure, the main line needs to be set as double lines. At present, the double-line schemes that have been built in China often adopt the juxtaposition of two single-line box girders. However, the maglev vehicle is "rail-holding" operation. The top surface of the box girder is equipped with a track structure, and the side is equipped with a contact rail system and cables for power supply to the maglev vehicle and other auxiliary facilities. However, it is used for emergency evacuation of passengers. Maintenance channels, sound barriers, etc. cannot be set. In order to meet the needs of emergency rescue and daily maintenance, one way is to set a beam between two single-line box girders, and support special s...
