Abstract

A ballastless long rail laying method of the invention relates to a construction method of rail laying after welding regular length-fixed rail into a long rail. The invention aims to provide a construction method to weld the length-fixed rail into the long rail for rail laying, which comprises a technical scheme that after welding the length-fixed rail into the long rail, the long rail is transported to the construction field of rail laying and then is welded to meet the requirement of the whole rail seamless line. The method of the invention is mainly applied in ballastless rail laying of high-speed railways and passenger transportation dedicated lines.

Description

technical field

[0001] The invention relates to a construction method for rail laying of a ballastless track, in particular to a construction method for laying rails after welding ordinary fixed-length rails into long rails in advance. Background technique

[0002] The existing rail transit projects at home and abroad have gradually increased the requirements for high-speed and stable transportation facilities, especially the requirements for the laying of ballastless track rails. Since the laying process needs to be carried out in different environments, the existing fixed-length track Laying technology has been difficult to meet the requirements of laying high-speed seamless lines. Contents of the invention

[0003] The object of the present invention is to provide a construction method for laying rails after welding common fixed-length rails into long rails in advance.

[0004] The object of the present invention is achieved through the following technical proposals: t...
