近年来,混凝土预制构件生产技术有了较大的进展,特别是混凝土的养护工艺更为突出,出现了不少新技术、新设施,为缩短混凝土预制构件的养护周期,加快模板周转,大幅度地提高构件产量和质量不断地作出了新的成绩。混凝土养护工艺,原是构件生产中的一项薄弱环节,以间歇式蒸汽养护坑为例,养护周期有的长达15小时以上,蒸汽耗用量有的高达1000公斤/米~3以上,明显地拖了混凝土构件预制行业的后腿。为突破这一薄弱环节,近几年来出现的连续式养护立窑、折线型隧道
In recent years, the production technology of prefabricated concrete components has made great progress. In particular, the maintenance technology of concrete has become more prominent, and many new technologies and facilities have appeared. In order to shorten the maintenance cycle of concrete prefabricated components and accelerate the turnover of the template We have continuously made new achievements in improving the output and quality of components. The concrete curing process was originally a weak link in the production of components. Taking intermittent steam curing pits as an example, some maintenance cycles lasted for more than 15 hours, and steam consumption was as high as 1,000 kg/m3 or more. Dragging the hind legs of the precast industry for concrete components. In order to break through this weak link, the continuous conservation shaft kiln and fold tunnel have emerged in recent years.
