Anti-electricity shed crossing multiple existing electrified railways and construction method

Abstract

The invention provides an anti-electricity shed crossing multiple existing electrified railways. The anti-electricity shed comprises stand columns and a crossing protective device arranged above the stand columns; the stand columns are distributed on the two sides of a track set to be crossed and arranged in the operation direction of the track set to be crossed, the crossing protective device comprises a steel base plate, a transverse beam, a 64-type railway military beam and an anti-electricity insulation device; the steel base plate is welded to the tops of the stand columns, the beam is welded to the top of the steel base plate, the transverse beam is arranged in the operation direction of the track set, the 64-type railway military beam is erected in the direction perpendicular to thebeam so as to be applicable to crossing the track set, and the anti-electricity insulation device is installed on the top of the 64-type railway military beam. The anti-electricity shed has the advantages that normal safety operation of the railway can be protected, it is ensured that construction work above the railway is not affected by high voltage current, and the construction safety is protected.

Description

technical field [0001] The present invention relates to the field of design and construction method of an anti-electricity shed, and more specifically relates to an anti-electricity shed spanning multiple existing electrified railways and a construction method. Background technique [0002] Due to the low voltage of ordinary railway catenary lines, the insulation and anti-electricity isolation materials of the commonly used anti-electricity shed structures spanning single-line ordinary electrified railways cannot meet the insulation and anti-electrical isolation requirements for high-voltage insulation across high-speed railway catenary lines. At the same time, the general anti-electricity shed has a small span, poor anti-tilt and anti-overturning stability, and can only meet the requirements of crossing single-track railways. For multi-line high-speed railways with more than two lines, it is difficult to use the general anti-electricity shed disclosed in the prior art. [0...
