Medium-and-low speed magnetic levitation railway low route continuous arched supporting rail beam structure and construction method

Abstract

The invention discloses a medium-and-low speed magnetic levitation railway low route continuous arched supporting rail beam structure. The structure comprises a reinforced concrete bottom plate, a rail row, a plurality of rows of track rail supporting tables, a reinforced concrete top plate, flow guide rail brackets and a plurality of reinforced concrete arched posts, wherein a transponder mounting position is arranged between a left track rail supporting table and a right track rail supporting table in each row of track rail supporting tables; the flow guide rail brackets are arranged on the two sides of the reinforced concrete top plate; the reinforced concrete arched posts are arranged on the reinforced concrete bottom plate along the track line direction at equal intervals; the bottom of the reinforced concrete top plate is fixedly connected with the top of each reinforced concrete arched post; the rail row is arranged at the top of the reinforced concrete top plate through the track rail supporting tables; a transverse arch is arranged in each reinforced concrete arched post; a longitudinal arch is formed between every two adjacent reinforced concrete arched posts. The transverse drainage requirement on a low route at a dual-line road section is convenient to meet, and the difficulty on construction of a rail structure on the upper part can be reduced.

Description

technical field [0001] The invention relates to the technical field of low-level line structures for medium and low-speed maglev transportation, in particular to a continuous arched rail bearing beam structure and a construction method for low-level lines of medium-low speed maglev railways. Background technique [0002] Medium and low-speed maglev rail transit is a new type of transportation. At present, there are few research results at home and abroad, and there are even fewer lines in operation around the world. At present, there are only the commercial operation line of the medium and low speed maglev railway in Japan in March 2005-Eastern Hills Line and the commercial operation line of the medium and low speed maglev railway in South Korea in June 2014. However, China's medium and low-speed maglev transportation currently only has the National University of Defense Technology test line, the Qingchengshan test line, and the Tangshan test line, and there is no official l...

Problems solved by technology

[0006] (2) Most of the rail bearing beams are box-shaped structures

However, the subgrade rail bearing beams of low-lying lines generally have small structural dimensions, and it is difficult for personnel to enter the box-shaped structure, and the maintenance is difficult

[0008] (4) The box-type rail bearing beam is placed on the subgrade surface, and it is difficult to implement horizontal drainage between lines

However, due to the large number of small components and the cast-in-place construction method of the pier-type rail-supporting beam, its construction accuracy is difficult to control, which directly affects the construction quality of the track and the running safety of the train

[0012] (3) The structure of the upper track is limited by the structure of the supporting pier-type rail beam. The layout of the rail row cannot be placed randomly, and must be accurately set according to the position of the pier and the transverse width of the structure

This increases the difficulty of construction, especially in curved areas.
