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， ...

Group 1: Metro Line 2 Phase II - The main structure of Longchuan Road Station has successfully topped out, achieving multiple records and completing the main structure 20 days ahead of schedule [3] - The station is part of the 8.9 km underground Line 2 Phase II, which connects the eastern part of Licang District with the city center and is expected to enhance transportation convenience for residents [3] Group 2: Metro Line 5 - The construction of the section between Changle Road Station and Eight Number Pier Station has achieved a breakthrough in shield tunneling technology under complex geological conditions, with a settlement control precision of 0.54 mm [5] - The completion of the protective pile construction at Lake Island Station has laid a solid foundation for subsequent excavation and structural work, finishing 69 days ahead of schedule [5] Group 3: Metro Line 7 - The main structure of all 7 stations in the second phase of Line 7 has been topped out, marking significant progress and multiple firsts in the construction timeline [6] - This line will facilitate rapid north-south connectivity, enhancing urban rail transit and boosting economic development along the route [6] Group 4: Metro Line 9 - The successful tunneling of the "Yongxing No. 1" shield machine under the墨水河 marks a record for the longest waterway crossing (130 meters) in the construction of Qingdao Metro Phase III [7] - The first phase of Line 9 is a key east-west backbone line in northern Qingdao, with a total length of 16.63 km and 13 stations planned [7]

针对超高混凝土侧墙施工难题，项目团队研发"三阶浇筑法"，在0.92米极限操作空间实现"零错台、零 漏浆"；推行"小立法管控+单板制考核"双轨机制，优化23项工艺参数，最高单月班组奖励差达40%。同 时，创新半自动移动式大型超高钢模板台车，提升模板周转率至12次，每延米节约混凝土0.15立方米， 降低碳排放18%。在钢管柱安装关键环节，79根12吨重钢管柱通过引孔优化、数控定位等技术，实现安 装精度误差小于3毫米。施工高峰期，320名建设者昼夜奋战，单日最高出土量3300立方米。 下王埠站位于李沧区金水路与巨峰路交叉口，是2号线二期首座车站，为地下两层、局部三层结构，总 长282.8米，最大宽度53.6米(约为标准站2倍)，承担2号线与15号线同层换乘及双联络线功能。 下王埠站的封顶，不仅为青岛地铁2号线二期后续建设奠定基础，更以多项工艺创新为青岛地铁超高结 构施工树立范本，助力城市轨道交通网络完善。 齐鲁晚报.齐鲁壹点记者赵波 该站地处青岛东西、南北交通"双动脉"交叉地带，面临地质条件差、管线密集、车流大等多重挑战。建 设团队创新采用"明盖结合+半幅盖挖顺做"工法，通过"倒边施工"实现道路通行与施工两不误；应 ...
