以预应力混凝土容器替代钢制容器,不仅节省钢材,节省投资,而且维护费用低,使用寿命长,又非常宜于建在地下或半地下。因此,大型原油储罐、水池、污水处理中巨型沉淀池、天然气柜及各种料仓等,愈来愈多地设计成预应力混凝土圆罐或圆筒。近些年由于绕丝机性能不断改进和绕丝工艺的完善,使得预应力筒罐建设速度、质量有了很大提高。1971年我们开始绕丝研究。十几年来,我们针对不同工程,对绕丝机不断进行了适
Replacing steel containers with prestressed concrete containers not only saves steel and saves investment, but also has low maintenance costs and long service life. It is also very suitable for underground or semi-underground construction. Therefore, more and more large-scale crude oil storage tanks, water tanks, huge sedimentation tanks for sewage treatment, natural gas tanks, and various silos are increasingly designed as prestressed concrete round tanks or cylinders. In recent years, due to the continuous improvement of the performance of the winding machine and the improvement of the wire winding process, the construction speed and quality of the prestressed cans have been greatly improved. In 1971 we began winding wire research. For more than ten years, we have continuously adapted the reeling machines for different projects.
