Abstract

It relates to the engineering technology science, in particular to a novel track layer for urban rail traffic engineering and its construction method. The novel track layer comprises lifting and walking trolleys, a connecting truss beam, a track running mechanism and a supporting structure. Horizontal extending and vertical supporting structures of each lifting and walking trolley are operated firstly so as to lift the whole novel track layer to a height at which a track material is hoisted and unloaded. A hoisting car is used to lift up the track material to leave from a flat trunk and a material supporting cushion. The novel track layer continues to walk forward to a designed mounting position of a track section, and then the track material is unloaded. Steel tracks are connected and a temporary track section support is mounted to fix a newly mounted track section.

Description

TECHNICAL FIELD

[0001] The present invention relates to engineering technology science, in particular to a novel track layer for urban track traffic engineering and its construction method.BACKGROUND ART

[0002] At present, in the track construction of urban track transit engineering in China, track layer equipment mainly includes three types: a fixedly assembled door type structure, a manual and hydraulic fixed-distance variable-span door type structure and an automatically retrieved electric stepless variable-span door type structure. Temporary running tracks need to be layed for the three types of track layers to run. The temporary running tracks are pre-layed on tunnel sidewalls on both sides of a main line or a structure floor, with track distances being generally 2800 mm, 3000 mm, 3100 mm, 3800 mm, etc. The temporary running tracks are fixed on the tunnel sidewalls or the structural floor by special steel structural buttresses. Due to the narrow space of an underground tunnel struc...
