摘要
Abstract
Taking the aging renewal and renovation of the gas pipeline network in City A as an example,the risk assessment methods for gas pipelines are ana-lyzed,and a safety checklist method combining qualita-tive and semi-quantitative methods is proposed.The ex-pert investigation method is used to formulate the gas pipeline safety checklist,and specific inspection con-tents are provided.Based on the safety checklist,the gas pipelines are evaluated to form a gas pipeline safety assessment form,and the main risk problems ex-isting in municipal gas pipelines are sorted out.By ap-plying urban gas pipeline aging renewal and renovation technologies(excavation and replacement technology,trenchless repair technology,and installation of ca-thodic protection systems),a renovation plan is pro-posed,which includes the renewal of the gas pipeline itself,the addition of an intelligent pipeline network monitoring system,and the optimization of the gas leak-age detection system.关键词
