全苏国立建筑工业化研究院制定了一种如图1所示的新型坑式养护窑。窑中设有一系列水封槽,以提高其密封性,其中包括窑盖与窑壁间的水封槽及沟槽中的水封槽。养护过程结束时,将水封槽中的水排除,并以抽风机抽出窑内的蒸汽-空气混合气,使构件逐步冷却。在回水管中设有专用的水封槽,可使窑内的蒸汽在此冷凝,不排向车间。全苏混凝土钢筋混凝土研究所的试验及
The National Institute of Building Industrialization of the Soviet Union has developed a new pit conservation kiln as shown in Figure 1. The kiln is equipped with a series of water-sealing grooves to increase its tightness, including a water-sealing groove between the kiln cover and the kiln wall and a water-sealing groove in the groove. At the end of the curing process, the water in the water-sealing tank was removed, and the steam-air mixture in the kiln was drawn out with an aspiration fan to gradually cool the components. There is a special water seal tank in the return pipe to allow the steam in the kiln to condense here, not to the workshop.
