Preparation method of high-strength HDPE corrugated pipe

The invention discloses a preparation method of a high-strength HDPE corrugated pipe, and relates to the technical field of pipeline preparation. The preparation method of the high-strength HDPE corrugated pipe comprises the following steps: step 1, mixing: proportioning polyethylene and various auxiliary materials, and putting the polyethylene and the various auxiliary materials into a mixer for fully mixing; the raw materials mixed in the mixer are conveyed to a plastic extruding machine through a feeding machine, the raw materials are heated and plasticized in the plastic extruding machine and extruded into a pipe blank through the plastic extruding machine, and then the pipe blank is fed into a corrugated pipe forming machine for sizing and shaping. By adding calcium carbonate, the strength of the pipe body is further enhanced, the preparation effect of the pipe body is guaranteed, by arranging a fixing structure in the cutting mechanism, when the pipe body needs to be cut, a screw rod drives pipe clampin
