Core Viewpoint - The Jinan High-tech East District Yunba project has entered the empty load trial operation phase, with significant progress in construction and the removal of construction barriers, enhancing urban traffic flow for citizens [1][3]. Group 1: Project Overview - The Yunba project is a key public transportation initiative in Jinan, emphasizing the principles of "convenience for the public, benefits for the people, and minimal disruption" during construction [3]. - The project has successfully removed over 465,000 square meters of construction barriers, allowing urban roads to gradually "return" and improving travel for citizens [1]. Group 2: Construction Strategies - To minimize disruption, the project team has implemented various strategies, including optimizing designs to relocate construction areas and compressing barriers to reduce their impact on traffic [3][8]. - A significant adjustment was made by moving the construction line south to utilize the roadside green belt, avoiding the closure of nearly 6 kilometers of motor vehicle lanes and all non-motor vehicle lanes [7]. Group 3: Efficiency Improvements - The project team has compressed the distance between barrier isolation piers and foundation pits to just 20 centimeters in the critical area of Tangye Road to maximize space for public use, resulting in a total barrier reduction of 23,000 square meters [10]. - In Spring Garden Road, the construction barriers reduced a four-lane road to two lanes, but through optimized pile foundation design and prefabrication of rebar cages, the team completed the work in just 40 days, significantly improving construction efficiency [11]. Group 4: Broader Impact - The Yunba line not only represents the speed of urban development but also reflects the commitment to serving the public, with every space saved and time reclaimed contributing to the city's warmth [19]. - Other projects, such as the Jinan Metro Line 4 and Line 6, are also progressing with barrier removal, promising further improvements in urban traffic flow and citizen travel experience [21].

作为济南市重点建设的公共交通项目，高新东区云巴自启动建设以来，始终将"便民、利民、不扰民"作为建设理念。由于云巴属于线性工程，围挡范围不 仅覆盖站点，更贯穿整条线路，面积大、影响广。如何最大限度压缩围挡、缩短工期、减少对市民生活的干扰，成为建设者面临的首要课题。为此，济南 高新东区云巴建设项目部多措并举，从多个方面推动"撤围还路"。 优化设计"挪位置" 争分夺秒"抢工期" 在春园路，施工围挡使双向四车道缩为两车道。为尽快恢复交通，项目部通过优化桩基设计、统一墩柱尺寸提升模板周转率、推行钢筋笼工厂预制等措施 大幅提升施工效率，最终该路段从围挡设置到撤除仅用40天，实现"速战速决"。 （世纪大道站围挡拆除后） 在世纪大道站至春园路站区间，原施工方案需占用机动车与非机动车道之间的绿化带，将封闭近6公里的机动车道及全部非机动车道。项目经理王永吉带 队现场踏勘，反复研究论证，最终提出将线路南移，全部转入路侧绿化带施工。这一调整虽增加了施工难度，却成功避免了对城市交通的干扰。 极限压缩"挤空间" 唐冶中路至围子山段虽仅1公里长，但地处唐冶核心区，周边商圈、社区、写字楼密集，交通压力大。为最大限度"让路于民"，项目部将围挡 ...

齐鲁晚报·齐鲁壹点 季明智 空载试运行期间，将重点对各设备系统和整体系统进行安全性、可靠性测试及考核，对运营作业人员培 训、故障模拟和应急演练等情况进行检验。 高新东区云巴建成后，将与年底通车运营的轨道交通4、8号线一道，显著激活区域联通。5座换乘站 （彭家庄站[以下均为工程名]衔接地铁2、4号线，唐冶站、程家庄站衔接4号线，春博路站、山东职业 学院站衔接8号线）无缝连接济南轨道交通骨干网络。初期、近期将采用2编组列车（满载约140人/列， 最高时速80公里），其准点、独立路权的特点，将有效解决公交出行拥堵痛点，大幅提升沿线居民通勤 和企业职工跨园区往来的便捷性，强力助推高新东区产城深度融合发展。 济南轨道交通集团以"项目提升年"为总牵引，认真落实"四抓四提升"工作要求，强化各类要素保障，推 动云巴项目建设不断提速增效。建设过程中，联合参建单位编制4部标准化施工手册，提升工程标准化 施工和质量管控水平；创新应用防落梁锚杆定位卡具，创下单月最快架设轨道梁约11500吨的纪录。自 2023年12月23日全线首桩开钻，至2025年5月19日土建全面完工，仅用17个月。施工期间践行"少围一米 是一米"、"少移一棵是一 ...
