Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1~5 , the method for removing and replacing the support layer and the substructure in this embodiment is to use steel pad beams to be erected on the second support layer 12 that needs to be removed for construction (such as figure 1 Shown in the dotted line box in ) as the supporting structure of the passage rail 4, to ensure the normal operation of the track line. The structure of the steel pad beam is as figure 1 As shown, it includes two longitudinal beams 1 arranged longitudinally along the track, the longitudinal beams 1 are I-shaped steel structures, and the webs of the longitudinal beams 1 are arranged vertically. The two longitudinal beams 1 are connected by the beam 2 arranged horizontally along the track to form an overall structure. The beam 2 is usually assembled by two pieces of channel steel. Th...

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...
