承插式自应力混凝土压力管的钢筋骨架是一个有喇叭口的圆筒体,由数十根主筋与螺旋环筋组成。主环筋交叉点要求有足够强度的连接。以前是在交叉点处靠人工用细铁丝连接的,而自动点焊机是在交叉点处进行点焊,这样不但提高了工效,而且大大提高 Socket self-stress concrete pressure pipe reinforced skeleton is a bell mouth cylinder, composed of dozens of the main reinforcement and spiral ring. The main ring intersections require a sufficiently strong connection. Previously at the intersection by artificial fine wire connection, and automatic spot welding machine is at the intersection of spot welding, so that not only improves the work efficiency, but also greatly increased
