中新网廊坊11月19日电 (邢璐 宋敏涛 王洋洋 马皓)19日，作为“轨道上的京津冀”标志性工程，北京轨道交通22号线(平谷线)正式启动河北段高楼站至齐心庄站区间U型槽铺轨作业。
北京轨道交通22号线(平谷线)是京冀首条跨省域轨道交通线路，项目线路全长81.82公里，分为北京段和河北段，共设车站22座。其中，河北段全长约31.56公里，共设车站5座。
中铁二局集团有限公司轨道交通22号线(平谷线)工程轨道安装工程三标项目经理高铎伦介绍，北京轨道交通22号线(平谷线)河北段铺轨工程按照线路减震设计要求，采取双块式整体道床、梯形轨枕道床、现浇钢弹簧浮置板道床及道岔形式铺设。目前，河北段高楼站至齐心庄站区间的U型槽铺轨基地已建设完成并开始铺轨工作。
北京轨道交通22号线(平谷线)项目建成后，河北廊坊三河市燕郊镇到北京城市副中心最快仅需9分钟，到达北京CBD(东大桥站)最短时间约32分钟，将有效缓解跨界道路交通压力，大幅提升跨省通勤群众出行效率。(完)
