寒区隧道的排水和防冻保温措施,往往在使用后若干年内就需要翻修,为了长期地解决寒区隧道的冻胀和结冰等病害,需采取一定的主动供热措施,目前国内外许多寒区隧道采用的主动供热的防冻保暖措施有衬砌加热、排水沟供暖等,但常规的各种电力和燃煤方式的加热方法,都存在能耗大、运营成本高等缺点。所以,寒冷地区迫切需要一种能耗小、运行成本低的主动防冻供暖技术,从而能够有效地根除隧道病害。寒区公路隧道地源热泵型防冻保暖技术是对隧道进行主动供热的节能技术,既能长期地解决寒区隧道的冻胀和结冰等病害问题,又有比常规的加热方法能耗小、运营成本低等优点。
In order to solve the problems such as frost heaving and icing in long time, it is necessary to take certain active heating measures. At present, many domestic and foreign cold District tunnel active heating of the antifreeze thermal protection lining lining heating, drainage ditch heating, etc., but the conventional heating methods of various electricity and coal-fired methods, there is energy consumption, high operating costs shortcomings. Therefore, in the cold area, there is an urgent need for an active antifreeze heating technology with low energy consumption and low running cost, so that the tunnel disease can be effectively eradicated. Cold area road tunnel ground source heat pump antifreeze technology is an active energy-saving heating tunnel technology, both long-term solution to the cold area of the tunnel frost heaving and icing and other diseases, but also less energy consumption than the conventional heating method , Low operating costs and other advantages.
