Preparation process for preparing double-wall corrugated pipe material

The invention discloses a preparation process for preparing a double-wall corrugated pipe material, which comprises the following steps that raw materials for preparing a double-wall corrugated pipe are guided into a material mixing shell through a feeding pipe, a motor stirs the raw materials in the material mixing shell at a high speed through a stirring rod, a valve is opened, the materials fall on a sliding seat through the valve, and a pressure sensor obtains weight data; the auxiliary valve is opened, the material is guided into the feeding and extruding assembly from the sliding seat, the feeding and extruding assembly mixes and extrudes the material, and the material for preparing the double-wall corrugated pipe is obtained. According to the preparation process for preparing the double-wall corrugated pipe material, a weighing assembly, a sliding seat, a spring assembly, a pressure sensor, a limiting frame, two groups of first adjusting plates and a first sliding rod are arranged in the device and mat
