摘要
对综合管廊墙体裂缝、管道腐蚀、局部防腐层损坏、管道热变形、管道漂浮等问题进行分析,提出采取优化管廊结构、加强级3PE防腐层、对局部防腐层采用光固化保护套防护、方形补偿器、抗漂浮设计、天然气舱室防火及防爆设计等措施,以确保工程本质安全。
Problems of cracks in wall of utility tunnel,pipeline corrosion,damage of local anticorrosive layer,thermal deformation of pipeline,pipeline floating and so on are analyzed. It is proposed to adopt measures such as optimizing the structure of utility tunnel,using reinforced grade 3 PE anticorrosive coating,protecting the local anticorrosive layer with light curing protective sleeve,installing square compensator,antifloating design,natural gas compartment fireproofing and explosion-proof design to ensure the intrinsic safety of the project.
