中新网杭州10月1日电(奚金燕洪奇金宸弘徐可)机械轰鸣、穿梭忙碌……金秋十月，浙江交通集团衢丽 铁路、金建高铁、金台铁路头门港支线二期等铁路建设项目数千名建设者坚守岗位，在跨海大桥墩台 上、在穿山越岭的隧道深处，以实干为笔、汗水为墨，抢抓"黄金施工期"，跑出项目建设"加速度"。 衢丽铁路：5000多人奋力冲刺关键节点 在全长10.592公里的衢丽铁路衢江特大桥施工栈桥上，指挥员的指令与机械运转声交织，工人们身着工 装、头戴安全帽，熟练操作橙红色的旋挖钻机、汽车泵等设备完成钻孔、浇筑作业。他们是这个国庆、 中秋假期里衢丽铁路全线5000余名一线建设者的缩影。 浙江交通集团衢丽铁路衢江特大桥建设现场 。洪奇摄 "目前衢丽铁路已进入冲刺攻坚关键期。衢江特大桥是一块要啃下的'硬骨头'，作为衢丽铁路项目最长 桥梁，它跨越两条铁路线、两条高速公路、一条油气管线和衢江，施工涉及产权单位多、安全风险高、 协调组织难度大，是全线重难点工程及控制性工程。为争取年底完成衢江特大桥跨芝溪48米连续梁合 龙，我们必须抓住施工黄金时间，争分夺秒、全力推进。"浙江交通集团衢丽铁路建设指挥部相关负责 人说。 作为浙江省"大花园"运输通道建设 ...

21日，在金建高铁兰溪东站高铁站内，随着第一对500米长钢轨在工人与大型设备的精准配合下稳 稳落定，新建金华至建德高速铁路兰溪至建德段铺轨施工正式启动，项目建设取得重大进展。 金建高铁作为国家中长期铁路网规划和浙江省铁路建设"八八计划"项目之一，自既有金华站引出， 向北经兰溪市、建德市，在建德站接入杭黄高铁，全长64.51公里，设计时速250公里。沿线设金华、兰 溪东、大洋、建德等4座车站，其中兰溪东站和大洋站为新建车站。本次启动铺轨的兰溪至建德段，需 完成正线铺轨87.1公里，站线铺轨6.63公里，并铺设道岔30组。 截至7月底，金建高铁累计完成投资83.033亿元。当前，项目路基、桥梁、隧道工程均已全部贯 通，站房工程与"四电"工程正有序推进，铺轨工程全面加速实施。（记者 张帆 金思成 通讯员 徐张 时 宽兵） 为确保铺轨工程安全、优质、高效推进，建设者高峰期可组织1000余名建设者同步奋战，单日铺轨 进度最高可达4.5公里。 ...

8月11日，随着一列满载500米长钢轨的运输列车缓缓驶入金建高铁兰溪东站铺轨基地，金建高铁兰 溪段正式进入长轨存储阶段。 金建高铁兰溪东至建德站先开段正线长度43.5km，正线铺轨87.1km，站线铺轨6.63公里，铺道岔30 组。此次首列500米长钢轨的顺利进场，不仅为下一阶段全线铺轨工作提供了充分条件，也为金建高铁 兰溪东至建德段顺利完成各项剩余工程节点打下了坚实基础。 金建铁路是连接金华与建德的重要交通纽带，全长64.51公里，设计时速250公里，起于金华站，止 于建德站，沿线设有4座车站。其中，金华站和建德站是既有车站，兰溪东站和大洋站为新建车站。 作为国家快速铁路网中"黄山至金华"铁路通道的组成部分，金建高铁向北可连接杭黄高铁，并可延 伸接入合福高铁，向南则有望连通沪昆高铁、金温铁路，而在另一方面，其还可串联起杭黄高铁和沪昆 高铁，是构成北至黄山、南达雁荡山、途经千岛湖、诸葛八卦村等集名山、名水、名胜为一体的"黄金 旅游线"的重要组成部分。 在建成并投入运营后，金建高铁可串联起"黄山旅游经济圈""浙中城市群"等多个经济圈，对于完善 区域铁路网结构布局，促进沿线旅游资源开发等具有重要意义。未来，杭州城 ...
