“SSIS-698英雄登场”平陆运河G75SSIS-698英雄登场兰海高速钦江大桥右幅格子梁顺利合龙

  中新SSIS-698英雄登场网钦州11月8日电(记者 杨陈SSIS-698英雄登场)平陆运河集团8日介绍,世界最大整体提升跨径和吨位的钢管混凝土系杆拱桥——平陆运河G75兰海高速钦江大桥右幅格子梁日前顺利合龙,标志着大桥右幅主体结构全部贯通。

  平陆运河G75兰海高速钦江大桥右幅格子梁共有25节段。为确保吊装施工顺利推进,平陆运河建设管理团队创新研发应用爬拱吊机,并采取东西岸对称、交替进行安装。爬拱吊机的“吊点智能调节系统”可保证格子梁在起吊过程中四个吊点平稳且受力均匀,实现格子梁高精准对接,进一步提高吊装效率,保证吊装过程的质量和精度。

  为突破桥位施工场地受限和潮汐水位变化的影响,高质量完成格子梁吊装,平陆运河建设管理团队采取周密措施,确保吊装过程中各项施工工序符合安全技术规范。

  在起吊前,平陆运河建设管理团队多次组织讨论格子梁吊装技术,对吊装工序、爬拱设备工艺、起重吊装作业、高空作业等进行全面的安全技术交底,同时进行严格的爬拱、试吊、负重论证,研判潮汐水位规律,缩减格子梁的运输时间,并组织专业技术人员落实起吊前关键工序的检查验收。

  起吊过程中,平陆运河建设管理团队利用可视化监控设备对爬拱吊机操作进行实时数据采集、观测、反馈,真正做到线上“看”得见,线下“控”得住,实现智慧化施工监管、智能化安全监控、数据化技术监测,助力吊装施工平稳、高效。

  当前,平陆运河G75兰海高速钦江大桥正全力加快施工进度,即将进入桥面及附属施工环节,力争在春节前实现右幅全面建成通车。(完)
