公路小桥涵冬季施工,保温养生是一个困难问题,使用蒸气养生费用高,又很不方便。几年来,我们利用酒糟保温养生效果很好。酒糟既能保证一定温度又能保持一定湿度,能够保证工程质量,达到设计要求,并且费用低廉,节省大量资金,经济效益较高。我们认为这个办法很好,有必要向大家介绍。酒糟保温养生方法简单。如果是地势低平的地方,可用酒糟将小桥涵全部盖上;如果桥涵地势较高,可将 Small bridges and culverts in winter construction, thermal insulation is a difficult issue, the use of steam health costs are high, and very inconvenient. In recent years, we use the thermal insulation of distiller’s grains is very good. Lees can not only ensure a certain temperature but also maintain a certain humidity, to ensure the quality of the project to meet the design requirements, and low cost, save a lot of money, high economic efficiency. We think this approach is very good and it is necessary to introduce it to everyone. Leucorrhea insulation method is simple. If it is a low-lying place, you can use lees to cover all the small bridges and culverts; if the bridge and culvert is high, you can
