摘要
根据长江岸线整治总体要求及整治原则,长江沿线散、杂货码头泊位后方敞开式堆场开始推进提质改造,以满足环保及港区生产要求。文章结合具体案例,介绍了异形网架结构的特点、安装方案,并从整体顶升工艺和高空散拼工艺两方面出发,探讨了复杂环境下异形网架结构的安装方法,旨在为类似项目提供参考。
According to the general requirements and principles of the Yangtze River shoreline renovation,quality improvement and transformation began to be promoted in the open storage yard behind the berths of bulk and general cargo wharves along the Yangtze River to meet the requirements of environmental protection and port production.Combined with specific cases,this paper introduces the characteristics and installation scheme of irregular grid structure,and discusses the installation methods of irregular grid structure in complex environment from two aspects of overall jacking process and high-altitude scattered assembly process,aiming to provide reference for similar projects.
