Monolithic track bed track structure capable of being rapidly assembled

Abstract

The invention discloses a monolithic track bed track structure capable of being rapidly assembled. The monolithic track bed track structure capable of being rapidly assembled comprises a track plate and steel rails erected on the track plate through fasteners, wherein the track plate is fixedly arranged on a foundation below the line through supports. Compared with the prior art, the supports arranged between the foundation below the line and the track plate can effectively support the track plate, rapid installation and locating of the track plate can be achieved, the purpose that the requirement for traveling of trains can be immediately met after installation is accomplished is achieved, and the monolithic track bed track structure has the advantages of being high in efficiency and accuracy, convenient to construct, and capable of being well applied to the situation that on the premise that traveling is not interrupted, maintenance or replacement of a monolithic track bed can be carried out within the skylight time.

Description

technical field [0001] The present invention relates to the field of railway track technology, and specifically refers to a track structure of a rapidly assembling integral track bed used in new construction, reconstruction, operation and maintenance of high-speed railways, ordinary railways, subways, urban railways, etc. Background technique [0002] At present, various types of integral ballast bed structures at home and abroad have been widely used in domestic and foreign railways due to their advantages of less maintenance work, simple structure, strong integrity and clean surface, such as the German Rehda double-block ballastless Track, Borg slab ballastless track, Japanese Shinkansen slab ballastless track, trapezoidal sleeper integral ballast bed, domestic CRTS type Ⅰ, Ⅱ, Ⅲ slab ballastless track, CRTS Ⅰ double block ballastless track, etc. In the actual application process, there are the following problems: [0003] The support of the underground foundation (bridge,...

AI Technical Summary

Problems solved by technology

[0003] The support of the underground foundation (bridge, tunnel, concrete support structure on the subgrade) of the integral ballast bed structure needs to be poured with concrete between the track slab and the offline foundation. Therefore, the materials used in the track laying need a certain setting time. That is, after the track structure is laid, it needs a certain maintenance time; therefore, because the track structure cannot realize the condition that the track can be driven immediately after the track is laid, it cannot adapt to the maintenance requirements of the current high-speed railway and subway in the operation process. When the structure cannot meet the needs of driving, it cannot be repaired within 3-4 hours of skylight time to meet the driving requirements immediately
