[0016] As shown in Figure 1 and Figure 2 The utility model discloses a reinforced HDPE pipe, including inner pipe 1, at least one outer pipe 2, wherein the outer pipe 2 is arranged on the outer circumferential surface of the inner pipe 1 in spiral winding mode. The inner hole 21 of outer pipe 2 is filled with epoxy resin body 3 that can harden and form spiral reinforcing structure.

[0017] This reinforced HDPE pipe has an inner pipe 1 and an outer pipe 2. The outer pipe 2 is spirally wound around the outer circumference of the inner pipe 1. The outer pipe 2 is filled with epoxy resin 3, which can harden to form a spiral reinforcing structure. Both the outer pipe 2 and the epoxy resin 3 can provide spiral reinforcement around the inner pipe 1. This not only enhances the compressive strength of the inner pipe 1 using the outer pipe 2, but also enhances the compressive strength of the inner pipe 1 using the epoxy resin 3. Therefore, this reinforced HDPE pipe has higher compressive strength, can be used under high pressure, and can avoid excessive shrinkage deformation and cracking. This not only ensures smooth water flow during use, but also prevents water leakage, solving many problems for users. This reinforced HDPE pipe has very high reliability and applicability.

[0018] Both the inner pipe 1 and the outer pipe 2 are made of HDPE material. The epoxy resin body 3 can be filled in the factory or at the construction site. The epoxy resin body 3 is filled in liquid form and hardened after curing. This meets the requirements for producing the reinforced HDPE pipe.

[0019] The pitch of the outer tube 2 is 10mm to 20mm. This not only facilitates manufacturing and molding, but also ensures that the reinforcing effect of the outer tube 2 on the inner tube 1 is very stable and reliable, thus enabling the reinforced HDPE pipe to have very high reliability and applicability.

[0020] like Figure 1 and Figure 2 As shown, the outer circumferential surface of the outer tube 2 is connected to the outer circumferential surface of the inner tube 1 by an arc transition. This helps to improve the assembly strength and stability of the outer tube 2 and the inner tube 1, thereby enabling the outer tube 2 to play a more stable and reliable reinforcing role on the inner tube 1, and further helping to improve the reliability and applicability of the reinforced HDPE pipe.

[0021] like Figure 1 and Figure 2 As shown, the outer pipe 2 and the inner pipe 1 are an integral structure. This not only improves manufacturing convenience but also gives the reinforced HDPE pipe a more reliable structure, thereby helping to further improve the applicability of the reinforced HDPE pipe.

[0022] like Figure 1 and Figure 2 As shown, a spiral steel strip 4 is inserted into the inner hole 21 of the outer tube 2, and the spiral direction of the spiral steel strip 4 is the same as that of the inner hole 21. The spiral steel strip 4, together with the epoxy resin body 3, can further improve the structural strength, thereby providing a more stable and reliable reinforcement for the inner tube 1, and thus helping to further improve the reliability and applicability of the reinforced HDPE pipe.

[0023] As shown in Figure 2 , the diameter of the spiral steel strip 4 is greater than or equal to one fourth of the inner hole 21 aperture, and the diameter of the spiral steel strip 4 is less than or equal to one half of the inner hole 21 aperture. This not only facilitates the manufacture and installation of the spiral steel strip 4, but also ensures that the spiral steel strip 4 can play a very stable and reliable reinforcing role, thereby helping to further improve the applicability of the reinforced HDPE pipe.

[0024] As shown in Figure 2 , the outer diameter of the outer pipe 2 is greater than or equal to one eighth of the outer diameter of the inner pipe 1, and the outer diameter of the outer pipe 2 is less than or equal to one fifth of the outer diameter of the inner pipe 1. This not only facilitates manufacturing, but also plays a very good reinforcing role, and can control the use of raw materials, which can make the reinforced HDPE pipe have higher applicability in water supply and drainage.

[0025] As shown in Figure 3 , the outer pipe 2 has two, and the spiral winding directions of the two outer pipes 2 are the same. This not only facilitates manufacturing, but also plays a more stable and reliable reinforcing role, thereby helping to further improve the reliability and applicability of the reinforced HDPE pipe.
