A toe-shaped track beam and a straddle-type monorail transit system

Abstract

The invention discloses a toe-shaped track beam and a straddle-type monorail traffic system, which comprises: a beam body connected end to end in sequence; a first flange plate connected to one side of the bottom of the beam body; a second flange plate, It is connected to the other side of the bottom of the beam body; the connecting position is arranged on the first flange plate and / or the second flange plate and is used for connecting the track sleeper block. The present invention does not need to set supports, anchor boxes and other structures in the tunnel, which can greatly reduce the section of the tunnel, reduce the construction cost, and avoid all loads concentrated on the bottom of the tunnel, effectively and evenly dispersing the force on the bottom of the tunnel.

Description

technical field [0001] The invention relates to the field of rail traffic, in particular to a toe-shaped track beam in an underground section of a straddle type monorail and a straddle type monorail traffic system. Background technique [0002] After the straddle-type monorail enters the ground, in order to ensure the manufacturing accuracy of the track, the structure of the support-type prefabricated track beam is mostly used in the tunnel. This structure makes the train load and the load of the track beam itself concentrate on the support pier. , the lower part of the support also needs an anchor box, so that the tunnel space needs to accommodate a series of components such as track beams, supports, and anchor boxes, and the lower space is wasted. The economy of the underground section of the seat monorail. Further, the above-mentioned support-type prefabricated track beams will also cause concentrated tensile pressure at the bottom of the tunnel, so it is almost impossib...

AI Technical Summary

Problems solved by technology

[0002] After the straddle-type monorail enters the ground, in order to ensure the manufacturing accuracy of the track, the structural form of the support-type prefabricated track beam is mostly used in the tunnel at present. This structural form makes the train load and the load of the track beam itself concentrate on the support pier , the lower part of the support also needs an anchor box, so that the tunnel space needs to contain a series of components such as track beams, support, anchor boxes, etc., the space in the lower part is wasted, and the overall size of the tunnel section is too large, which significantly increases the project cost and reduces the span. The economy of the underground section of seated monorail

Furthermore, the above-mentioned support-type prefabricated track beams will also cause concentrated tensile pressure at the bottom of the tunnel, so it is almost impossible to use it in shield tunnels and underground tunnels with thin bottoms.
