筑牢安全生产堡垒 "党建链"赋能"安全链" 安全和质量是企业发展的生命线，锚定零事故、零死亡的"双零"安全目标，在建设、运营、生产一线，从零开始、向零奋斗，济南轨道 交通集团以"党建链"赋能"安全链",筑牢安全生产堡垒。 济南轨道交通集团严格落实安全生产"党政同责，一岗双责",同时扣紧压实全员安全责任链条，践行"4321"安全管理理念，深入推进安全 生产治本攻坚三年行动，深化重大风险隐患排查，筑牢汛期暑期安全防线，还在全国轨道交通单位中首个真正做到"把隐患当成事故处 理"。 济南轨道交通集团还创新推出"隐患随手拍"活动、"安全积分超市",以接地气的活动让人人成为安全守护员。 从人防到技防，济南轨道交通集团还构建起"线上+线下"联合监管模式，依托集团信息化平台，搭建集团、子公司、施工项目三级视频监 控系统，并配备专职值班人员，实现24小时不间断在线巡查和实时"云调度"。同时，建立工人"一人一档一卡一码一马甲"管理台账，以 信息化手段强化全员实名制管理，配备检查记录仪和无人机辅助开展现场检查，为安全监管安上"千里眼"和"飞毛腿"。 济南轨道交通4号线实现全线电通、8号线开启全线动车调试；济南低运量轨道交通高新东区 ...

近日，济南轨道交通4号线、8号线建设一线"节"报频传，4号线位里庄出入线至泉城公园站（以下均为工程名）区间实现"长轨通"；8号线彩龙路站至山东 现代学院站区间热滑试验也正式启动……项目建设加快推进。 4号线：位里庄至泉城公园站实现"长轨通" 作为贯穿济南主城区东西的交通大动脉，4号线工程线路长、站点多，施工环境复杂，尤其是铺轨作业面临战线绵长、作业空间受限、多专业交叉施工以 及减振降噪要求高等多重挑战。为确保工程如期推进，建设者们迎难而上，打响了铺轨攻坚战。 项目团队创新采用"机铺+散铺"组合施工模式，实施"双向对铺"，有效破解了空间狭小、交叉作业多的难题。施工高峰时期，全线同时开设8个作业面，8 台新型自变形轮式铺轨吊、8台自变形轮胎式罐车高效协同，创下了单日铺轨670米的速度纪录，大幅提升了施工效率。 为保障列车运行平稳舒适并降低环境影响，4号线关键区段采用钢弹簧浮置板道床技术，在轨道与道床间设"缓冲带"，利用弹簧压缩吸收振动能量，可降 噪10至15分贝。同时，建设者运用高精度闪光焊接技术，将全线长钢轨无缝锁定，焊接精度控制在3毫米内，大幅提升轨道平顺性，优化乘客乘坐体验。 云巴：动车调试加快推进 截至目 ...

Core Viewpoint - The successful installation of the last 22-meter track beam marks the completion of the track beam connection for the High-tech East District Yunba project, which is significant for enhancing transportation in the region [1] Group 1: Project Overview - The High-tech East District Yunba project spans 30.7 kilometers with 32 stations and one comprehensive yard, integrating with existing metro lines 2, 4, and 8 to facilitate transportation for residents and employees [3] - The project aims to connect industrial spaces in the High-tech East District with high-capacity rail transit, addressing the "last mile" issue to promote urban integration [3] Group 2: Safety Management - The installation faced challenges such as working under a 500kV high-voltage line and required meticulous coordination due to the varying lengths and weights of the beams, with the longest beam measuring 60 meters and weighing 120 tons [4] - A detailed inspection checklist was developed to ensure safety during the beam installation process, contributing to the project's rapid progress [6] Group 3: Technical Innovations - The project utilized integrated bridge and track design, demanding high precision in the placement of anti-fall beam anchor rods, with allowable height deviation not exceeding 10 millimeters over 90 meters [7] - A specialized tool was created to maintain anchor rod positioning, achieving a horizontal deviation of 15 millimeters and vertical deviation of 8 millimeters, enabling a monthly installation rate of 11,500 tons, surpassing the national average of 5,000 tons [9] Group 4: Construction Strategy - To meet the 2025 completion deadline, a "see the gap and insert the needle" strategy was employed, allowing for simultaneous operations at multiple points to ensure timely delivery of track beams [11] - All 32 stations have been capped, with ongoing decoration, equipment installation, and system testing to ensure readiness for operation by the end of the year [13]
