一、前言自瑞典从七十年代初期研制成功了能耗低、效率高、结构简单、使用方便的混凝土真空脱水机组和柔性吸垫以来,混凝土真空技术的应用在世界各国得到了迅速的发展我国从七十年代后期自江苏省建科所、南京真空泵厂和杨州机械厂研制成功了同类的混凝土真空脱水机组和柔性吸垫以来,混凝土真空技术在国内亦得到了迅速推广并在道坪、路面、预制和现浇混凝土构件的施工中,取得了良好的技术经济效果。
I. INTRODUCTION Since the early 1970s, Sweden successfully developed concrete vacuum dewatering units and flexible suction pads with low energy consumption, high efficiency, simple structure, and easy use. The application of concrete vacuum technology has rapidly developed in various countries in the world. Since the late 70’s since the successful completion of similar concrete vacuum dehydration units and flexible suction pads by Jiangsu Jianshe Institute, Nanjing Vacuum Pump Factory and Yangzhou Machinery Factory, the concrete vacuum technology has been rapidly promoted in the country Good technical and economic results have been achieved in the construction of pavements, prefabricated and cast-in-place concrete components.
