摘要
对电伴热的设计理念、施工工艺和费用计算等方面进行了阐述,并分别与排空防冻、循环放水、充注防冻液三种保温方案进行经济分析和技术比较,最终得出电伴热保温系统是现阶段公路隧道最为可行实用的消防管道保温措施。
The paper illustrates the design idea, the construction craft, and cost calculation of the electric heat tracing, undertakes the economic analysis and technical comparison of three insulation schemes, including the evacuation and anti-freezing, the circulating water, and the filling of anti-freezing liquid, and concludes the electric heat tracing insulation is the feasible and practical fire-fighting pipeline insulation measures for road tunnels nowadays.
