Problems solved by technology

This treatment method solves the problems of daily line maintenance and emergency evacuation of passengers, but there are still some defects: the top surface of the evacuation passage is much lower than the vehicle floor surface, and it is extremely inconvenient for personnel to evacuate; Crowded and stampede incidents are prone to occur when it is large; the maintenance platform is integrated with the rescue and escape passage, and the cables placed on the maintenance platform break or leak when passengers evacuate, which will cause personal injury to passengers

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as Figure 1-3 The cross-sectional view of the existing track beam shown has been described in detail in the background art, and will not be repeated here.

[0038] Such as Figure 4-8 As shown, the evacuation and maintenance platform of the present invention includes crossbeams 2 arranged at longitudinal intervals between two single-line box girders 1 that are juxtaposed, and the crossbeams 2 connect the two box girders 1 into one body to increase the overall transverse stiffness; The longitudinal maintenance channel 3 on the beam 2 and the evacuation channel 4 above the maintenance channel. Columns 7 are arranged at both ends of the crossbeam 2 to support the evacuation channel 4. The maintenance channel 3 includes a maintenance channel bottom plate 31 and a lower longitudinal beam 32 arranged under the column 7 on the...

Abstract

The invention discloses a hold rail-type track transportation bridge evacuation maintenance platform, which comprises a horizontal beam that is set between two parallelly set single line box beams and that is set at interval along the longitudinal direction and is characterized in that the platform provided herein also comprises a longitudinal maintenance channel set above the horizontal beam and an evacuation channel set above the maintenance channel; and two ends of the horizontal beam are provided with uprights used for supporting the evacuation channel. According to the invention, the evacuation maintenance platform is set on the horizontal beam; evacuation channel and maintenance channel structures are adopted; the evacuation channel and the maintenance channel are not influenced by each other; and the platform provided herein has the advantages of simple structure, convenient use and high safety.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a rail-holding rail transit bridge evacuation maintenance platform. Background technique [0002] Both maglev rail transit and straddle-type monorail transit adopt a unique "rail-holding" operation mode, and the small-section single-track box girder that meets the vehicle limit is the most economical beam type solution for "rail-holding" rail transit. 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 Transit, figure 2 It is a cross-sectional view of the straddle-type monorail transit track beam in Chongqing, image 3 It is a cross-sectional view of the track beam of a medi...
