高速铁路运营线无砟轨道地段插入道岔技术研究
Research on Inserting Turnout into High Speed Ballastless Track Railway in Operation
摘要
Abstract
With the development and improvement of China high-speed railway network, a large number of new railways are introduced into the existing stations or hubs and turnouts need to be installed urgently on busy ballastless track lines, which challenges high-speed railway development. With reference to the track connection scheme of one high-speed railway to the existing high-speed railway station, this paper proposes the technological scheme by removing existing ballastless track and laying new ballastless turnout. Such measures as setting up security isolation wall, blocking one line for construction while allowing the adjacent line in operation, and employing new materials, new processes and new technologies are taken to ensure construction safety, shorten construction period and reduce impact on railway operation. The scheme resolves the technological problem of track connection in high-speed railway stations or hubs and fulfills the introduction of new high-speed railway into existing hubs.关键词
