Abstract
The invention provides a highly-strengthened inner-fin and outer-ripple type plastic pipe and a manufacturing method thereof. The highly-strengthened inner-fin and outer-ripple type plastic pipe mainly comprises a tubing body which is formed by abnormal-shaped strips in a spiral winding and welding mode. The tubing body comprises a cylindrical pipe wall, a hollow reinforcing rib wound on the cylindrical pipe wall in a spiral mode, and a strengthened inner fin which is arranged in the hollow reinforcing rib and vertical to the pipe wall. The strengthened inner fin divides the hollow reinforcing rib into two parallel hollow cavities. A welding-formed junction surface is arranged on the strengthened inner fin. The main conception of the highly-strengthened inner-fin and outer-ripple type plastic pipe and the manufacturing method thereof is that the highly-strengthened inner-fin and outer-ripple type plastic pipe is formed by the plastic abnormal-shaped strips in a spiral winding mode and through sol fusing, two sides of each plastic abnormal-shaped strip are provided with tubular protrusions containing hollow cavities inside, the two hollow cavities which are close to each other and arranged between the adjacent plastic abnormal-shaped strips which are wound in a spiral mode form the hollow reinforcing rid after being fused, and the vertical strengthened inner fin is formed in the fused portion of the middle of the hollow reinforcing rib. The highly-strengthened inner-fin and outer-ripple type plastic pipe and the manufacturing method thereof have the advantages that excellent ring stiffness and excellent pipe-soil interaction are guaranteed, and the strength is high at the same time. In addition, the manufacturing method of the plastic pipe can achieve production under the condition that a common winding-structure wall tubing manufacturing device is equipped with an adaptive die head, a shaper and an auxiliary clamping roller.
