Method for prefabricating and constructing separated rail structure

Abstract

The invention discloses a method for prefabricating and constructing a separated rail structure. The separated rail structure comprises a separated rail bearing groove and a factory-prefabricated rail system. The method for prefabricating the separated rail structure includes the following steps of preparing materials, controlling temperatures, arranging the rail bearing groove, cleaning a groove area, mounting a tie plate under a rail, placing the steel rail, checking and sealing the end, treating before pouring and pouring polymer materials. The method for constructing the separated rail structure includes the following steps of hoisting a rail bearing groove rail system, conducting foundation treatment, placing the prefabricated rail bearing groove and adjusting the geometry, connecting and fixing, pouring concrete, maintaining and removing tools. According to the method for prefabricating and constructing the separated rail structure, the construction technologies of factory prefabrication, field assembly and the like are used, the fastening-down rail temperature of the rail system is effectively controlled in a factory, the influence of the site construction environment and climate is avoided, the construction cost of the rail is lowered, the efficiency is improved, and maintaining and replacing are more convenient.

Description

technical field [0001] The invention relates to a separate track structure prefabrication and construction method, belonging to the technical field of track prefabrication and construction. Background technique [0002] In traditional rail transit, rails are fixed together with rail bearing platforms or sleepers through fasteners, and then placed on ballasted or ballastless track beds. During the entire construction process, there are many procedures and a long construction period, which affects the surrounding environment. The impact is relatively large, and the construction efficiency is low; the fasteners are easy to loose during use. In order to ensure driving safety, the fasteners need to be checked and re-tightened frequently. The maintenance workload is heavy and the cost is high; In the process, the noise and vibration generated during the driving process will radiate a large amount to the surrounding environment, which has a huge impact on the lives of the surroun...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a separate track structure prefabrication and construction method. Through the separate track structure prefabrication, the function separation of the rail bearing groove and the track plate is realized, and the factory production of the track system is carried out, and then through on-site construction. There are technical problems in the construction process of the track structure, such as long period, great impact on the environment, low construction efficiency, and high maintenance cost, so as to effectively solve the problems existing in the above-mentioned prior art
