湖北省建筑总公司科研所和混凝土预制厂,根据武汉地区的地理、气象条件,结合生产实际,在长线台座预应力混凝土圆孔板的养护生产中,采用了以黑色塑料薄膜覆盖代替草袋覆盖,春、秋、冬三季再加罩“钢骨架、玻璃钢顶面太阳能养护罩”。它与自然养护相比,能使养护周期缩短1/2～2/3,能节约养护费用10%,节约养护用水80%。现场文明,构件养护质量良好。钢骨架玻璃钢顶面太阳能养护罩为多节可移式。这种罩用25 ×
According to the geographic and meteorological conditions of the Wuhan area and the actual production, the research institute and prefabricated concrete prefabrication plant of Hubei Provincial Construction Corporation adopted the black plastic film cover instead of the straw bag to cover the long-line pedestal prestressed concrete circular orifice plate. , Spring, autumn and winter seasons will be covered with “steel skeleton, fiberglass top solar protection cover.” Compared with natural conservation, it can shorten the maintenance cycle by 1/2 to 2/3, save conservation costs by 10%, and conserve conservation water by 80%. On-site civilization, good quality of component maintenance. Steel skeleton fiberglass top solar protection cover is multi-section movable. This hood uses 25 ×
