钢筋接头用套管冷压连接，经工程实践后，证明冷压连接法具有连接速度快，接头质量可靠、节约用电等优点。在江阴长江公路大桥上已完成了5000余个钢筋冷压接头，并已得到监理工程师的认可，现结合工程实际介绍冷压接头的特点、挤压设备、挤压工艺及技术经济指标。
After the engineering practice, it is proved that the cold connection method has the advantages of fast connection speed, reliable joint quality and saving electricity. In Jiangyin Yangtze River Highway Bridge has completed more than 5,000 steel cold joints, and supervision engineers have been recognized, are combined with the actual project describes the characteristics of cold joints, extrusion equipment, extrusion technology and economic and technical indicators.
