LNG罐体PSV平台预制施工技术

Construction Technology for Deep Foundation Pit of LNG Tank Rainwater Connection Well

针对龙口液化天然气(LNG)罐体压力安全阀(PSV)平台的预制施工技术进行了设计,对技术准备、施工方法、基础和钢构件的验收标准做了相应规定,确定了检验方法和安装工艺。将PSV平台换分为3个框架和管道进行预制安装,连接横梁和斜撑加以固定,最后在以上结构完成后铺设管道,搭建液化天然气输送的安全控制平台。该平台的搭建保证了液化天然气在中转、储存和管道运输的安全。

This article designs the prefabrication construction technology for the platform of Pressure safety valves(PSV)in Longkou LNG tank,specifies the technical preparation,construction methods,acceptance standards for foundations and steel components,and determines the inspection method and installation process.The PSV is divided into three frames and pipes for prefabrication and installation,connecting the crossbeam and slant support for fixation,and finally laying the pipes.The construction of the platform ensures the safety of LNG in transit,storage and pipeline transportation.
