Preferably, balls are provided at the opposite side where the socket is connected to the buffer tube and where the outer wall of the socket is connected to each other.

Preferably, the wall thickness of the socket part is 10 to 12 mm.

Preferably, the steel ring includes two semi-circular bodies that are movably connected at one end and separated at one end, and a fastener that fixedly connects the free ends of the two semi-circular bodies.

The beneficial effects of the utility model are: 1. The pipe body is made of modified polyethylene material, which has good corrosion resistance, good hygienic performance and long service life, and can reduce the resistance during transportation, reduce Energy consumption; 2. The compressive performance of the pipe body is improved by reinforcing ribs, steel mesh, steel ring and other components; 3. During the installation process of the pipe body, only the socket part of a specific structure needs to be inserted into the socket part. The installation is simple and convenient, and the pipe body is not easy to be damaged, and the sealing performance is good.

detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figures 1 and 2, a modified engineering plastic pipe for buried use includes a pipe body made of modified polyethylene material. Tube 2. The outer wall of the corrugated outer pipe 2 is provided with reinforcing ribs 21 between two corrugations, which improves the resistance of the pipe body to external forces, prevents the pipe body from breaking during handling and construction, and can make the pipe body The shape of the annular outer wall of the pipe body is better, and the wall thickness is more uniform. Both the corrugated outer pipe 2 and the smooth inner pipe 1 are provided with a layer of steel mesh, through which the compressive performance of the pipe body can be further improved. The pipe body is made of polyethylene material, which has good corrosion resistance, good hygienic performance and long service life, and can reduce resistance during transportation and reduce energy consumption.

A steel ring 3 is provided at the junction of the two engineering plastic pipes, and the steel ring 3 includes two semi-circular bodies with one end movably connected and one end separated, and fasteners for fixedly connecting the free ends of the two semi-circular bodies. During installation, it is only necessary to buckle the two semi-circular bodies of the aperture 3 at the junction of the two engineering plastic tubes, and then fix the steel ring 3 firmly by screws or buckles, which further improves the firmness of the tube body , and improve the sealing performance of the pipe body.

The smooth inner tube 1 includes an inner tube body 11 , and a socket portion 12 and a socket portion 13 respectively provided at two ends of the inner tube body. During installation, it is only necessary to insert the socket portion 12 of one engineering plastic pipe into the socket portion 13 of another engineering plastic pipe, and the installation is simple and convenient.

The socket part 12 includes a socket whose inner diameter is smaller than the inner diameter of the inner tube body 11, and a buffer tube connecting the inner tube body 11 and the socket, and the inner wall of the socket part 13 matches the outer wall of the socket part 12 socket tube. The inner wall of the socket part 13 is provided with an annular groove 14 on the contact side with the socket, and the outer wall of the socket is provided with a sealing ring 15. After the installation is completed, the sealing ring 15 is just located inside the annular groove 14, further improving the two engineering. Sealing properties between plastic pipes.

The opposite side where the socket is connected to the buffer tube and the connection between the outer wall of the socket are rounded, so that the socket is not easy to damage the inner wall of the socket tube during insertion into the socket tube, and avoid breaking the seal of the plastic tube performance.

Balls are provided on the opposite side where the socket is connected to the buffer tube and at the connection between the outer wall of the socket, which not only makes the socket less likely to damage the inner wall of the socket tube during insertion into the socket tube, but also helps to slide the socket Inserting into the socket pipe improves the installation efficiency of the socket part 12.
