Description

Polyethylene pipe for water supply with plastic outer protective layer for non-excavation

Technical Field

The utility model relates to a polyethylene pipe technical field especially relates to non-excavation is with polyethylene pipe for feedwater that has plastics outer protective layer.

Background

Polyethylene pipe is called PE pipe for short, the PE pipe has wide application field, wherein a water supply pipe and a gas pipe are two largest application markets, the PE resin is polymerized by monomer ethylene, and because the polymerization reaction conditions such as pressure, temperature and the like are different during polymerization, the PE resin with different densities can be obtained, so the PE pipe has the advantages of high-density polyethylene, medium-density polyethylene and low-density polyethylene;

in recent years, the trenchless technology is rapidly developed in China, the damage to the environment is small, the construction period is short, the cost is low, the traffic is not influenced, and the plastic pipe is more and more applied to underground engineering.

Disclosure of Invention

According to the technical problem, the utility model provides a polyethylene pipe for water supply with plastics outer protective layer for non-excavation which characterized in that includes protection strip, outer protection pipe, bandage, tubular product, apron, T type slider, the outer protection pipe of tubular product outside cover, outer protection pipe and tubular product closely laminate through coextrusion integrated into one piece, the outer protection pipe outside integrated into one piece has the protection strip, the protection strip is arc structure; the surface of the outer protection tube is provided with N placing grooves, wherein N is more than or equal to 2; the inside heat-seal of standing groove has the bandage, T type spout has been seted up respectively to the left and right sides wall of standing groove, two the inside sliding connection of spout has T type slider, the standing groove upside is provided with the apron, the left and right sides both ends of apron bottom are connected with T type slider top respectively.

The beneficial effects of the utility model are that:

the utility model can effectively protect the pipe by arranging the protection strip, the outer protection pipe, the bandage, the cover plate and the T-shaped slide block, is convenient for carrying the pipe, the cover plate slides by an operator, the cover plate drives the T-shaped slide block to slide in the T-shaped slide groove, when the cover plate completely communicates the placing groove with the outside, the bandage is exposed to the outside, the operator can pull the bandage to drive the pipe to slide, the operator can conveniently pull the pipe to carry out transportation underground, when the pipe is pulled close to the ground, the pipe can be effectively prevented from being in contact with the ground and being worn because of the protection of the outer protection pipe, and the protection strip is integrally formed outside the outer protection pipe, because the protection strip is of an arc structure, the contact area with the ground can be effectively reduced, when the ground is blocked by stones, the arc structure can more easily slide from the top of the stones, the friction that the stone slided the production to the tubular product is reduced, the operating personnel of being convenient for more carries out the tubular product transportation to can further reduce the area of contact of outer protection tube and ground, thereby wholly reduce with the frictional condition in ground, alleviate the phenomenon that tubular product received wearing and tearing greatly and take place, can carry out good protection when tubular product pulls the transport through this design, avoid tubular product and ground the condition of wearing and tearing to appear, guarantee that tubular product can not break when follow-up is used, prolonged life greatly.

Detailed Description

Example 1

The utility model provides a polyethylene pipe 4 for water supply with plastics outer protective layer for non-excavation, its characterized in that includes protection strip 1, outer protection tube 2, bandage 3, tubular product 4, apron 5, T type slider 6, the cover is equipped with outer protection tube 2 outside tubular product 4, outer protection tube 2 and tubular product 4 are tightly laminated through coextrusion integrated into one piece, the integrated into one piece has protection strip 1 outside outer protection tube 2, protection strip 1 is the arc structure; the surface of the outer layer protection tube 2 is provided with placing grooves 8, the number of the placing grooves 8 is N, and N is more than or equal to 2; the inside heat-seal of standing groove 8 has bandage 3, and T type spout 7 has been seted up respectively to the left and right sides wall of standing groove 8, and two inside sliding connection of spout have

T type slider

6, and 8 upsides of standing groove are provided with apron 5, and both ends are connected with 6 tops of T type slider respectively about 5 bottoms of apron.

Example 2

When the utility model is used, namely when the water pipe and the gas pipe are erected underground, an operator slides the cover plate 5, the cover plate 5 drives the T-shaped slide block 6 to slide in the T-shaped slide groove 7, when the cover plate 5 completely communicates the placing groove 8 with the outside, the bandage 3 is exposed to the outside, the operator can pull the bandage 3 so as to drive the pipe 4 to slide, the operator can conveniently pull the pipe 4 to drag so as to transport underground, when the pipe 4 is dragged close to the ground, the pipe 4 can be effectively prevented from being worn due to the contact with the ground due to the protection of the outer protection pipe 2, and the protection strip 1 is integrally formed outside the outer protection pipe 2, because the protection strip 1 is of an arc structure, the contact area with the ground can be effectively reduced, when the ground is blocked by stones, the arc structure can more easily slide from the top of the stones, the friction generated when the stones slide on the pipe 4 is reduced, the operating personnel of being convenient for more carry out the transportation of tubular product 4 to can further reduce the area of contact of outer protection tube 2 and ground, thereby wholly reduce with the frictional condition in ground, alleviate the phenomenon that tubular product 4 received wearing and tearing greatly and take place.
