齐鲁晚报·齐鲁壹点记者 赵波 夏日的青岛，地铁建设工地热潮涌动。7月8日，记者从青岛地铁集团获悉，近期地铁2号线二期、5号 线、7号线、15号线迎来多项关键节点突破——从附属结构封顶到盾构机精准贯通，从主体结构首板浇 筑到装配式施工创新落地，多线齐发的建设节奏，正为岛城轨道交通网络"拼图"按下"快进键"。 2号线二期：东川路站附属结构封顶 作为连接东岸城区与崂山的重要线路，地铁2号线二期近期传来好消息：东川路站配套附属结构A出入 口、1号风亭及安全疏散通道顺利实现结构封顶。据悉，2号线二期（东段）起于李村公园站，终于北宅 科站，建成后将进一步加密崂山区域轨道交通覆盖，助力崂山景区与主城区的快速联通。 5号线：双线贯通+主体开建 地铁5号线福宁立交站，车站主体结构仰拱首板成功完成浇筑。海云庵站-湖岛站区间（"海湖区间"）的 进展——随着"云瑞号"盾构机刀盘精准破岩而出，该区间左线顺利接收，至此海湖区间提前15天实现双 线贯通。据悉，这段区间地质复杂，穿越多处老旧建筑群和地下管线，盾构机需啃下坚硬的花岗岩层， 能提前贯通，靠的是精准的掘进参数控制和24小时动态监测。5号线建成后将串联起市南、市北、李沧 三大城区， ...

近日，北京市公共资源交易服务平台发布设计招标公告，地铁15号线将在新国展地区增设车站。根据公告披露的 信息，此次加站改造工程项目已由北京市发改委批准建设，投资额为3.15亿元。车站为两层侧式站，并设置3870 平方米的连廊建筑。值得一提的是，顺义区曾规划从T2航站楼西延首都机场线，连通15号线增设的这一车站，加 强首都机场与新国展间的交通联系。 新设车站将如何建设？ 根据此次发布的招标公告，地铁15号线服务新国展地区加站改造工程项目已由北京市发改委批准建设，投资额为 3.15亿元。车站均在地上，为两层侧式站，规模约9000平方米，并设有3870平方米的连廊建筑。 目前地铁15号线共设有孙河站、国展站、花梨坎站、后沙峪站等4座高架车站，其站台均采取的是高架岛式。 需要强调的是，目前，地铁15号线服务新国展地区加站改造工程项目进行招标的是设计方面的内容，包含方案设 计、初步设计、施工图设计等，因此，还没有更多具体的内容披露。 对于城市轨道交通线路来说，站台的形式大概可分为岛式和侧式两类。"侧式站台"的轨道位于中央区域，站台则 分列轨道两侧，更多出现在地面或高架车站，适合客流量波动较大的线路，乘客需在不同站台搭乘不 ...

在北京轨道交通三期建设规划中，亦庄线至5号线、10号线联络线属于起步较晚的，之前的信息也比较少。 但同时，这条线路又是很多沿线居民非常关心的，毕竟，这对于如果这三条线未来能贯通运营，对于南部地区的居民来说无疑是非常便利 的。 昨天，这条线路终于迎来了好消息。京投公司官网今天开始轨道交通亦庄线至5号线、10号线联络线工程第一次环评公示。通过建设联络线， 实现亦庄线与5号线贯通运营，与10号线换乘优化。 01 而亦庄线至5号线、10号线联络线工程要解决的就是这个问题。 根据环评公示的信息，工程南起现状肖村站，北至现状宋家庄站，全长约2.7公里。 不过这一信息与此前轨道交通三期规划公示以及亦庄线至5号线、10号线联络线工程的相关招标文件中信息不太一样。 此前的信息显示，联络线工程南起亦庄线肖村站，向北经宋家庄车辆基地后，分别与5号线宋家庄站、10号线成寿寺站衔接。 亦庄线目前是在宋家庄站与5号线、10号线三线换乘，因此宋家庄站也是北京轨道交通路网中换乘量最大的车站之一。 但如果乘坐亦庄线想继续向北，那就要从亦庄线下车，换乘5号线。如果想去国贸、西三环等地，则要下车换乘10号线。这多少都会给乘客带 来不便。 关于亦庄 ...

新京报讯(记者裴剑飞)6月25日，北京市基础设施投资有限公司发布北京轨道交通亦庄线至5号线、10号 线联络线工程环境影响评价第一次公示。此条联络线全长约2.7公里，中途不设站点，本期通过地下局 部新建线路和利用既有线路，实现亦庄线与5号线贯通运营、与10号线换乘优化。 作为连接北京中心城区与亦庄经开区的一条重要轨道交通线路，地铁亦庄线每天的早晚客流高峰十分显 著，特别是换乘节点——宋家庄站的客流压力更大，拥挤是每日的常态化情况。 北京地铁亦庄线起自丰台区宋家庄站，途经朝阳区、大兴区，终点止于通州区亦庄火车站，连接北京中 心城区与北京经济技术开发区。北京地铁亦庄线全长23.3千米；共设14座车站，其中地下站6座、高架 站8座；拥有宋家庄停车场1个停车场和台湖车辆段1个车辆段；列车采用6节编组B型列车。 这份招标文件提及一个关键信息——亦庄线与5号线和10号线未来均可以贯通运营，这意味着未来工程 的最终目标还是要实现三线贯通运营，而不只是目前环评公示提到的"亦庄线与5号线贯通运营、与10号 线换乘优化"。下一步，将通过线路优化、设备改造等方式，实施亦庄线与10号线的贯通运营。 北京市轨道交通指挥中心数据显示，亦庄 ...

提及早高峰时段的地铁5号线，拥挤似乎成了它的代名词。5月15日是5号线调整运营的首日，有不 少市民在网络平台上分享了自己的感受——"昨天五号线早高峰好像没那么挤了。"是否真的这样？记者 也前去体验了一把。 8点27分，记者走入打铁关站，站台上已经有不少市民排着队等候即将到来的地铁，不远处的电子 显示屏上，标明了下一班车到来的时间——"2分钟"。不多时，随着地铁的到来，周边的乘客熟练地涌 入车厢。在它离开后不久，又有一批新的乘客站满了站台。 "小交路从原来的蒋村-江晖路延长5个站到育才北路，使更多站点能够包含在这样高峰安排中，惠 及更多乘客，特别是其中还有人民广场这样的换乘站。这样的组合调整后，最大限度地发挥了现有列车 的运能，从而能够在高峰时段满足更多站点的乘客需求。"祝宁说。 也就是说，想要通过5号线在滨康路站换1号线、在人民广场站换2号线的乘客，今后换乘的速度只 会更快，等候的时间也将大大缩短。 后续地铁5号线的行车间隔还有望进一步缩短吗？祝宁表示，目前，杭港地铁已有增购列车安排， 因为增购列车从生产到使用会有一段时间的周期，后续将依据列车到达情况及实际客流，持续优化运营 方案，为广大市民提供更便捷、舒适 ...
