Description
Technical Field
The utility model relates to a novel PE pipe.

The pipe jacking construction is to overcome the friction force between the pipeline and the surrounding soil by means of the jacking equipment in the working pit, jack the pipeline into the soil according to the designed gradient and transport away the earth. After one pipe is pushed into the soil layer, a second pipe is pushed into the soil layer. The principle is that by means of the thrust of the main top oil cylinder, the pipeline, the relay and the like, a tool pipe or a heading machine is pushed from the inside of a working pit to the inside of a receiving pit through a soil layer to be lifted. The pipeline is buried between two pits after following the tool pipe or the heading machine. Patent publication No. CN 214946995U: the double-layer PE pipe for the pipe jacking comprises an outer layer PE pipe, wherein an inner layer PE pipe is connected inside the outer layer PE pipe, the length dimension of the outer layer PE pipe is consistent with that of the inner layer PE pipe, the length of one end of the inner layer PE pipe exceeds that of one end of the outer layer PE pipe, and a sealing gasket is arranged at one end of the inner layer PE pipe; the outer PE pipe comprises a jacket, and a protective layer is arranged in the jacket; the inner PE pipe comprises an adhesive resin layer, and a composite layer is arranged in the adhesive resin layer.
