Abstract


The ballastless track by a concrete or asphalt mixes replaced shot ballast track bed consisting of track structure in the form. Track Irregularity high, stiffness uniformity and good track geometry potential endure significantly reduce maintenance workload ballastless track railway countries has been developing rapidly. Especially the high-speed railway, some countries have ballastless track as the main structure of the track to comprehensively promote. This paper analyzes the ballastless track the status quo, and abroad, focusing on analysis of the ballastless track the development history and current situation in Germany, Japan, France, the United Kingdom, as well as analysis of the history of the development of the domestic ballastless track. Then the Suiyu line Ballastless track the significance of the test described, Suiyu line is my first time into segments laying track, during the pilot study of the construction process, but also for different types of non-ballasted track and line under the structure of the relevant data test, summarize laying experience. The construction of the test section, create our own intellectual property, non-ballasted track with Chinese characteristics has great significance. This paper studies the engineering of Suining-Chongqing line, while areas along the line Suiyu characteristics and engineering geological conditions. Focus on ballastless slab track double block ballasted track construction technology. Ballastless slab track construction is divided into the track plate prefabricated panels under concrete base construction, laying of track plate and CA Mortar key technology. Double block ballasted track construction is divided into the production of bi-block sleepers, double-block sleeper assembly laying. This paper analyzes SuiYu Line construction organization prepared in accordance with the principles of the preparation of the content and preparation of construction organizations started to prepare large-scale temporary works reasonable, scientific. The survey then Chongqing line manpower, materials, equipment. The last the project cost Suiyu line. The ballastless track ballasted track, can help achieve the maximization of investment returns. Then Ballastless track turnouts, carried out the analysis the Passenger Line fasteners, epoxy coated rebar ballastless track the large-scale use of the new material. On-site construction observation, key processes Suiyu line ergonomics. The ballastless track different types of per kilometer cost index calculation and analysis.
