随着我国高速铁路网建设的不断深入和完善,大量新建线路需要引入既有车站或枢纽,我国高速铁路建设运营线无砟轨道地段插入道岔的功能需求日显迫切,已成为制约我国高速铁路建设的关键技术难题。结合某新建高速铁路引入既有高铁站的接轨方案,提出拆除既有无砟轨道、新铺无砟道岔技术方案,通过设置安全隔离板墙,封锁一线施工,相邻正线单线行车,采用新材料、新工艺、新技术等系列措施,可确保施工安全和缩短工期,减少对运营的影响。该方案解决了高铁车站或枢纽无砟轨道接轨的技术难题,实现新建高速铁路线路与既有枢纽的成功引入。
As China’s high-speed railway network construction continues to deepen and improve, a large number of new lines need to be introduced into the existing stations or hubs, high-speed railway construction and operation of ballastless track into the turnout of the function requirements become increasingly urgent, has become a constraint to China’s high-speed railway construction The key technical problems. Combined with a new high-speed railway introduction of existing high-speed rail station program, put forward the demolition of existing ballastless track, the new shop without balustrade technology program, by setting the safety isolation wall, block the construction of the first line, adjacent to the mainline single-lane traffic, Materials, new technology, new technologies and other measures to ensure construction safety and shorten the construction period, reduce the impact on the operation. The solution solves the technical problems of high-speed railway station or hubless ballastless track convergence and realizes the successful introduction of new high-speed railway lines and existing hubs.
