Preparation method of connecting head for spiral plastic corrugated pipe ultradeep embedding

Abstract

The invention discloses a preparation method of a connecting head for spiral plastic corrugated pipe ultradeep embedding and the connecting head, and relates to urban construction. The end of a snakelike bearing component is fed in a pressed upper polytetrafluorine pressing wheel, and a roller guide device is adjusted; upper and lower polytetrafluorine pressing wheels are released; winding dip angles of four rollers are adjusted; dip angles of upper and lower pressing rollers and center lines of dip angles of rollers are maintained consistent; a mold temperature machine, a first extruder and asecond extruder are started; the first extruder extrudes inner chips; the second extruder extrudes outer chips; the upper and lower polytetrafluorine pressing wheels are pressed down; and the snakelike bearing component is inserted in the upper polytetrafluorine pressing wheel, so that the snakelike bearing component synchronously moves along with the inner chip and the outer chip, and then, is guided into the lower polytetrafluorine pressing wheel to guarantee the shape consistency of the outer chip and the snakelike bearing component. The preparation method can effectively resist outside backfilled soil to prevent deformation of pipe joints.

Description

technical field [0001] The invention relates to urban construction, in particular to a preparation method for a super-deep buried connector of a spiral plastic corrugated pipe. Background technique [0002] The system after the pipeline is buried needs to bear the gravity of the external soil. The weakest link of the system formed by the spiral plastic corrugated pipe is the joint between the pipelines. It is easy to break, deform, dislocate and leak under the gravity of the external soil. The use of steel pipes and other joints that can withstand heavy pressure, on the one hand, is costly, and on the other hand, it does not match the material of the plastic bellows, resulting in poor connection, easy to leak, and easy to deform and break the pipe and its connection. Contents of the invention [0003] One of the objectives of the present invention is to provide a method for preparing an ultra-deep buried joint of a spiral plastic corrugated pipe. The joint prepared by this...
