New construction method for non-stop high-speed rail

Abstract

The invention relates to a construction technology crossing an overhead line of a high-speed rail, in particular to a novel construction method crossing the high-speed rail without interruption. By the construction method, the problem of serious influence of the convention construction technology crossing the overhead line of the high-speed rail on the normal running order of the high-speed rail is solved. The novel construction method crossing the high-speed rail without interruption is implemented according to the following steps of (a) assembling crossing construction devices in advance within stipulated ranges of the two sides of the high-speed rail according to a skylight point time frame stipulated by the railway department; (b) respectively starting two rotation mechanisms in the skylight point time frame of the high-speed rail, and respectively driving two horizontal rotation arms to rotate by the two rotation mechanisms; (c) laying a plurality of bearing pipes between the two horizontal rotation arms; and (d) pulling a guide rope step by step to cross the high-speed rail by using a primary guide rope in the running time of the high-speed rail, and laying wires and grounding lines step by step. The construction method is suitably used for construction of the overhead line crossing the high-speed rail and is similarly used for construction of an overhead line crossing expressway, construction of an overhead line crossing a live circuit and the like.

Description

technical field [0001] The invention relates to a construction technique for straddling a high-speed railway, in particular to a novel non-stop construction method for straddling a high-speed railway. Background technique [0002] UHV AC and DC lines often need to cross the high-speed rail during the construction process. Because the high-speed rail adopts a fully enclosed, full-overpass design, and the high-speed rail travels at a high speed and has a high departure density, the railway department usually prohibits crossing the high-speed rail construction during the high-speed rail operation period, and only allows it during the high-speed rail skylight point period (in order to ensure that the high-speed rail During the maintenance time of equipment for safe operation), the network closure construction of crossing high-speed rail lines will be carried out. Therefore, the cross-high-speed rail line construction has the characteristics of short construction time, high cons...
