Technology of laying transport rails with track skeletons

Abstract

The invention relates to a technology of laying transport rails with track skeletons. The technology is characterized in that the track skeletons are laid step by step from the starting point A to the finishing point B, then ballast bed construction, steel rail welding and ballast bed arrangement are carried out step by step from the finishing point B to the starting point A, and the steel rails with the track skeletons are used for logistics transportation. The technology includes the steps of track skeleton assembly, track skeleton loading and transport, track skeleton laying, ballast bed construction, steel rail welding and ballast bed arrangement, and relates to at least five devices, namely the first device of a rail material transport railway car, the second device of a track skeleton laying unit, the third device of a track skeleton assembly pull rod, the fourth device of a track skeleton connector connection clamp and the fifth device of a split type steel rail support. The technology has the advantages that the related devices can move by means of the steel rails of the track skeletons, a gantry crane does not need to be arranged and the waling rails are high in mechanical degree, and efficient and orderly construction of ballastless tracks is guaranteed.

Description

technical field [0001] The invention belongs to the field of railway construction, in particular to a technology for laying self-track transport tracks. Background technique [0002] At present, the construction of ballastless track in the whole country includes the construction of passenger-only ballastless track and subway (light rail) ballastless track. In the construction site, the transportation channels for rail materials such as rail row and concrete are narrow, and the degree of mechanized logistics is low. It is necessary to increase the investment of manpower, material and financial resources such as erecting auxiliary equipment gantry cranes and laying steel rails for gantry cranes, which leads to slow construction progress, especially for subways. The space in the tunnel is even narrower, and the auxiliary equipment gantry crane cannot be erected, or the use of lifting equipment is affected due to space and terrain, and the utilization rate is low, which seriousl...

AI Technical Summary

Problems solved by technology

[0003] Therefore, whether it is possible to consider using the rails that come with the rails for logistics transportation, and whether it is a construction process for logistics vehicles or lifting equipment vehicles that rely on the rails that come with the rails, so that there is no need to add some extra manpower and material resources, thereby improving construction efficiency? The above thinking is accompanied by another problem. The current process of track laying and track bed construction is carried out at the same time. The track bed requires a 14-day maintenance period from the completion of the construction to the concrete strength meeting the requirements of logistics vehicles and lifting equipment vehicles. The time maintenance period cannot meet the normal construction requirements
