离心-振动一辊压法制管工艺是一种复合工艺,混凝土在离心成型的同时附加振动和辊压。美国从六十年代开始采用复合工艺制压力管,后来被雷蒙德公司发展为制作大直径圆管桩管节。我国采用这种复合工艺成型管节是在近几年才开始,首先在国家“六五”攻关项目大直径管桩研制中,研制成功了能同时实现离心、振动、辊压作用的制管成型机(简称离心振压机),并在连云港、宁波镇海、上海等地大直径管桩车间中投入使用。整个制管过程是自动化的,即将带钢筋 Centrifugal-vibration-rolling method is a kind of compound process. The concrete is added with vibration and rolling at the same time as centrifugal molding. Since the 1960s, the U.S. began adopting a composite process pressure pipe and was later developed by Raymond to produce a large-diameter pipe pile section. China’s use of this composite process to form pipe joints has only begun in recent years. First, in the development of large-diameter pipe piles for the national “6th Five-Year Plan” research project, the successful development of pipe forming that can simultaneously achieve centrifugal, vibration, and roll action. Machine (referred to as Centrifugal Vibratory Press), and put into use in large diameter pipe pile workshops in Lianyungang, Ningbo Zhenhai, Shanghai and other places. The entire manufacturing process is automated and will soon be reinforced
