“xxxxxx69日本”渝厦高铁重庆东至xxxxxx69日本黔江段全线铺轨完成

  中新xxxxxx69日本网重庆12月15日电 (张旭)xxxxxx69日本记者15日从渝黔铁路有限责任公司获悉,当天,在渝厦高铁白马山隧道出口施工现场,随着中铁十一局建设者将最后一对500米长钢轨顺利铺设到接轨点,标志着渝厦高铁重庆东至黔江段全线铺轨完成。

  渝厦高铁重庆段是国家“八纵八横”高铁网中渝厦通道的重要组成部分,从重庆站引出,途经渝中、南岸、巴南、南川、武隆、彭水等区县,止于重庆市黔江区,正线全长269.5公里,设计时速350公里。

  据悉,因为沿线地形地貌复杂,长钢轨加固、运输、铺设难度大,精度要求高等原因,要实现安全、优质、高效组织铺轨施工并不容易。

  为此,项目建设管理单位会同施工单位多次召开现场施工会,精心制定施工方案,细致把控技术标准和安全质量,严格落实无砟轨道施工前置条件确认,为铺轨创造有利条件。

  据中铁十一局铺轨施工现场负责人张家梁介绍,在钢轨运输和铺轨施工中,采用了先进的智能调度指挥系统和通道门视频监控及开闭状态监管系统,实时监控铺轨机、长轨运输车、焊轨车等设备,使铺轨施工、运输组织的智能化和可靠性得到大幅提升。

  渝厦高铁重庆段建成通车后,重庆中心城区至黔江区的列车旅行最快时间将从现在的4小时缩短至1小时内,对完善中国高速铁路网布局,加快形成重庆至厦门的高速铁路主通道,带动沿线地区经济社会发展具有重要意义。(完)
