Assembled digitalized prefabricated ballast bed module, production method thereof and rail

Abstract

The embodiment of the invention provides an assembled digitalized prefabricated ballast bed module, a production method thereof and a rail. The ballast bed module comprises rail plates, rail bearing tables and steel rail fasteners, the rail bearing tables are arranged on the upper surfaces of the rail plates and are used for fixing the steel rail fasteners, and the steel rail fasteners are used for fixing steel rails; and each rail plate is integrally in a strip shape. The rail bearing tables are arranged to be perpendicular to the length directions of the rail plates. The rail plates are provided with limiting structures used for limiting plane movement of the rail plates. The N track plates are connected end to end on a preset railway line to form a detachable track monolithic ballast bed, wherein N is a positive integer greater than 1. The assembled digital prefabricated ballast bed module provided by the embodiment of the invention has a detachable property, can be laid on a railway line to form a track for a train to run, can be prefabricated in a factory, can be assembled on site on the railway line, and is convenient to construct, stable in structural strength and convenientto maintain and recycle.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit engineering, and in particular to an assembly digital prefabricated ballast bed module, a production method thereof, and a track. Background technique [0002] Rail transportation is one of the important modes of transportation in life, and the track is the basis of transportation equipment. The track directly bears the train load and guides the train to run. The track structure must have sufficient strength and stability. At present, most of the domestic urban rail transit adopts the integral track bed, and the construction technology of cast-in-place concrete is adopted. The domestic high-speed railway with the world's first operating mileage adopts different types of prefabricated track slabs and CA mortar or self-compacting concrete pouring positioning technology, filling materials such as self-compacting concrete or CA mortar between the suspended track slab and...

AI Technical Summary

Problems solved by technology

If urban rail transit promotes the application of industrially produced prefabricated track slabs in order to achieve green construction, the underground railway will be limited by the transportation conditions of the tunnel space and the requirements for the fluidity and rapid solidification of filling materials. Not only the construction process is complicated, but the waste of filling materials is relatively large Many and low construction efficiency

The adjustment layer filled in the daily track transportation process is the weak link of the track structure, which is easily damaged and difficult to maintain. After the ballast bed is formed, it cannot be recycled and reused.
