Abstract

The invention discloses a novel rail system, which includes an assembled rail plate and an elastic rail locking system in a groove. The assembled rail plate comprises a rail plate body 1 and a prefabricated rail supporting table 2, and the prefabricated rail supporting table 2 is detachably mounted on the rail plate body 1 and forms a rail supporting groove together with the rail plate body 1; andthe elastic rail locking system is arranged in the rail supporting groove. The novel rail system has the beneficial effects that the rail supporting groove is realized by assembling and has the structural characteristics of continuous supporting and continuous locking; during construction, steel rail moving flash welding can be realized, and the construction efficiency is improved; and the prefabricated rail supporting table can be removed when a steel rail is replaced, the operating space is increased, the steel rail in the rail supporting groove is conveniently pulled out, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to a novel rail system, which is prefabricated in a factory and modularly installed on site, and belongs to the technical field of rail transportation. Background technique [0002] In recent years, the model of factory prefabrication and on-site assembly has been increasingly popularized in my country's construction industry. At the same time, this model runs through urban rail transit engineering and system product development, such as prefabricated floating slab tracks and trapezoidal sleeper tracks in urban rail transit. As a new type of rail transit system structure, the continuously supported track structure has the advantages of good vibration and noise reduction, low wheel and rail wear, long service life, good insulation performance, good ride comfort and small daily maintenance workload. It has gradually attracted attention in the field of domestic urban rail transit. At present, it has been applied to many tram lines a...
