Integrated forming method for HDPE double-wall corrugated pipe

The invention provides an integral forming method for an HDPE double-wall corrugated pipe. The integral forming method comprises the following steps: S1, putting an HDPE raw material into a first material chamber, putting an HDPE regenerated material into a second material chamber, putting a filling agent into a third material chamber, and adding other trace components into the third material chamber to be mixed with filling glue or independently adding the other trace components into a fourth material chamber. And S2, the discharging speed and the discharging amount of the first material chamber, the second material chamber, the third material chamber and the fourth material chamber are input in advance in a computer, automatic execution is achieved, and the discharging accuracy is guaranteed. S3, in the process that the materials enter the mixing container, the container continuously rotates, and it is guaranteed that the materials are fully mixed. And S4, after the materials are fully mixed, a material ext
