A temporary rail support device for the removal and replacement of the support layer of railway ballastless track

Abstract

The invention relates to the technical field of railway ballastless track disease eliminating, in particular to a temporary steel rail supporting device for disassembling and replacing railway ballastless track supporting layers. The temporary steel rail supporting device comprises steel sleeper beams for supporting temporary passing steel rails and supports fixed on supporting layers below existing rails at the two longitudinal ends of a to-be-constructed area. The steel sleeper beams include two longitudinal beams arranged in the longitudinal direction of the rails and the transverse beams located between the two longitudinal beams, the two ends of the longitudinal beams are laid on the upper end faces of the supports and anchored on the supporting layers below the existing rails at the two longitudinal ends of the to-be-constructed area, the transverse beams are arranged in the transverse direction of the rails, and the two ends of the transverse beams are fixed to the lateral portions of the two longitudinal beams respectively. According to the temporary steel rail supporting device, the steel sleeper beams are used for erecting the construction area overhead and supporting the passing steel rails, a railway line can normally run without stopping, and normal running of the rails is guaranteed; in addition, the disease problem in the supporting layers below the rails and lower structures of the rails can be thoroughly solved, hidden dangers of the rails can be thoroughly eliminated, and high popularization value is achieved.

Description

technical field

[0001] The invention relates to the technical field of railway ballastless track disease elimination, in particular to a temporary rail support device used for the replacement of a railway ballastless track support layer. Background technique

[0002] Ballastless track is widely used in China's high-speed railways due to its good stability, small maintenance workload, high ride comfort, long track service life, and low structural height. At the same time, high-speed railways require that the track must have high ride comfort. , requiring high stability of the underrail infrastructure. Although the design and construction of high-speed railways that have been built or are under construction have adopted unprecedented high-standard construction measures, due to my country's vast territory and complex railway construction conditions, there are still many factors that may affect the stability of ballastless tracks, such as Construction quality, foundation settlem...
