Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:

A kind of bis- high muscle enhancing winding pipe of PP, as shown in Figure 1, including that a kind of bis- high muscle of PP enhance winding pipe, including pipeline Main body 1, pipe main body 1 include the plastic-steel layer 2 in outside and the base 3 of inside；

As shown in Fig. 2, plastic-steel layer 2 includes two double high muscle 21 formed through spiral winding, the inside of every double high muscle 21 Steel band slot 211 is offered, steel band 212 is equipped in steel band slot 211, the outside of plastic-steel layer 2 is equipped with multiple rows equidistant in a ring The inside of the reinforcement convex ribs 22 of cloth, plastic-steel layer 2 is equipped with multiple reinforcement concave bars 23 equidistantly arranged in a ring；

As shown in figure 3, base 3 is erosion resistant coating 31 and metal shielding 32 respectively from inside to outside；

As shown in figure 4, the top of pipe main body 1 is equipped with interface 4, the outer circumferential walls of interface 4 are equipped with multiple annulars Protrusion 41,1 lower part of pipe main body are equipped with birdsmouth 5, offer multiple convex grooves 51 on the circumferential inner wall of birdsmouth 5.

Specifically, plastic-steel layer 2 is the plastic layer formed by polypropylene through thermoplastic, polypropylene impact resistance with higher, Engineering properties is tough, resists a variety of organic solvents and acid and alkali corrosion.

Further, the C/C composite layer that erosion resistant coating 31 is made of carbon fiber and resin, carbon fiber have good Corrosion resistance, the C/C composite layer with resin composition is most one of corrosion-resistant material.

Further, metal shielding 32 is the reticular structure layer by a plurality of copper oxide wire interleaved discs around formation, due to The corrosion resistance of copper oxide can be made of it cylindrical body reticular structure package erosion resistant coating 31, avoid erosion resistant coating 31 oppressed and Fracture.

It is worth noting that reinforcement concave bar 23 is corresponding with the position of convex ribs 22 is reinforced, by the interior outside of plastic-steel layer 2 Setting reinforces concave bar 23 and makes the bis- high muscle enhancing winding pipe structures of PP firmer with convex ribs 22 are reinforced.

It is worth noting that, convex groove 51 is adapted with annular protrusion 41, convenient for winding the bis- high muscle enhancings of two PP Pipe is connected by annular protrusion 41 with convex groove 51, makes to connect more compact.

In addition to this, interface 4, birdsmouth 5 and pipe main body 1 are an integral molding structure, and integrally formed structure is more Stablize.

The bis- high muscle enhancing winding pipe of the PP of the present embodiment as draining sewage pipe in use, being located at 1 inside of pipe main body The erosion resistant coating 31 for the C/C composite material being made of in base 3 carbon fiber and resin can resist invading for waste water and pollutant for a long time Erosion, not by the corrosion of acid-base material in waste water and pollutant；The metal shielding 32 being set between erosion resistant coating 31 and plastic-steel layer 2 It can effectively avoid external force extrusion pipe around the reticular structure of formation by copper oxide wire interleaved discs and cause the rupture of erosion resistant coating 31；Together When be not easy to degenerate positioned at the outermost plastic-steel layer 2 formed by polypropylene through thermoplastic of pipe main body 1 is not only corrosion-resistant, and in plastic-steel Double high muscle 21 are set on layer 2, and steel band 212 is set in the inside of double high muscle 21, so that weight of the pipeline in receiving earthing, simultaneously When pipeline being avoided to be mined, the arm of force of excavator causes pipeline breaking.When connecting the bis- high muscle of two PP enhances winding pipe, can lead to Annular protrusion 41 in piping one end interface 4 and the convex groove 51 in another pipeline one end birdsmouth 5 are mating So that two pipeline connections are more compact, then fixed by pipe jointer.
