Construction technology for replacing turnout of laying and replacing unit

Abstract

The invention provides a turnout replacement construction process of a laying and replacing unit. The turnout replacing construction technology of the laying and replacing unit comprises the following steps that S1, preparation work of equipment before construction is conducted is conducted; s2, turnout pretreatment: S2.1, turnout pre-laying; s2.2, turnout transportation; s2.3, welding the whole group of turnouts; and S3, replacing the turnouts. According to the turnout replacing construction technology of the laying and replacing unit, the pre-laying environment is improved, the turnout pre-laying efficiency and quality are improved by using construction equipment such as a turnout transport vehicle and a laying and replacing machine, large hoisting equipment is applied to the turnout replacing construction link, labor intensive operation is completed instead of manual work, and the construction efficiency is improved. The problems of many on-site constructors and high labor intensity are solved, damage to the turnout in the construction process is reduced, waste old materials generated in the construction process can be reduced through overall disassembly and assembly, a large amount of on-site old materials can be taken away through overall transfer, optimization and improvement are achieved on the basis of an existing construction method, and a safer, more efficient and more economical construction method is provided.

Description

technical field [0001] The invention relates to the technical field of switch replacement construction technology, in particular to a switch replacement construction technology of a laying and replacement unit. Background technique [0002] With the continuous development of society, the frequency of use of trains continues to increase, and the maintenance workload of the railway department is also increasing. The maintenance and replacement of railway lines with quality and quantity is an important guarantee for the safety of trains. [0003] The turnout is one of the weakest links in the entire track system, and it is the key equipment to limit the running speed of the train. The high-precision laying of the turnout is an important link to ensure the normal use of the turnout. This in turn ensures comfort and safety when the train passes. [0004] Restricted by factors such as the location, equipment, skylight point, construction cost, etc., in the laying construction of ...
