摘要
针对目前加油站双层油罐改造施工过程中涉及用火、起重、临时用电、高处作业、盲板抽堵、动土、进入受限空间七大作业风险,对罐池和工艺管道两部分,依抽排旧罐底油、管道冲洗、封堵盲板,油罐清洗、氮气置换,旧罐区土方开挖,旧罐拆除吊运;新管沟和新罐区开挖、新油罐安装土方回填、充水压罐,管线及配管安装调试、竣工验收投用,以及废旧油罐和管线的处置等十个关键环节的施工风险和控制要点进行了阐述,强调根据现场实际进行认真分析研判,采取有效措施,加强监督检查,确保无安全环保事故发生。
The revamp of double-layered oil tank in gas station is characteristic of tight time,heavy task and complex engineering,which involves seven kinds of high risk operations, including fire, lifting,temporary electricity,aloft work,blind plate plugging,moving earth, and entering restricted space. The construction process of tank pool and pipeline of double-layered tank is introduced respectively. On the basis of this,the control points for ten construction steps,such as bottom oil pumping and pipe flushing and then blocking blind plate,oil tank cleaning and nitrogen replacement,excavation of earth on the old tank area,old tank dismantling and lifting,excavation of new tank ditch and new tank area,new tank installation,earth backfill and filling water into tank,installation and commissioning of pipeline,completion acceptance,and disposal of waste tank and pipeline,are proposed respectively, which can provide reference for the construction and transformation of double-layered oil tank of gas station.
