近来,日本愈来愈多的工程中使用了预制钢筋混凝土连续墙,它利用现浇地下连续墙相同的机械挖掘沟槽,然后在沟槽中插入相互连接的预制钢筋混凝土板构筑而成。这种预制地下连续墙可以和地下结构连成一体,通称为预制地下室(PB),承受 Recently, prefabricated reinforced concrete continuous walls have been used in more and more projects in Japan. They utilize the same mechanical digging trenches as in-situ underground continuous walls, and are then constructed by inserting interconnected prefabricated reinforced concrete slabs in the trenches. This kind of prefabricated underground continuous wall can be integrated with the underground structure, commonly known as a prefabricated basement (PB).
