苏联于1956年秋在卡尔加达和艾克巴其多区域使用了用振动方法制做的钢筋混凝土杆,运行情况良好。圆形空心钢筋混凝土杆一般都是用离心回转机制造, 但该法需复杂的工厂设备,消耗大量电能,井劳动生产率低;使用振动方法可以弥补这些缺陷。根据此较,振动方法制造圆形空心杆产品的平均成本仅为离 In the fall of 1956, the Soviet Union used reinforced concrete rods made of vibrations in the regions of Calgada and Ike Badogdo, which performed well. Circular hollow reinforced concrete rods are generally manufactured using centrifugal rotary machines. However, this method requires complicated plant equipment, consumes large amounts of electric energy, and has a low labor productivity. The use of vibration methods can compensate for these defects. According to this comparison, the average cost of manufacturing a circular hollow rod product by the vibration method is only
