However, in actual use, due to different conveying media, it is difficult for traditional plastic pipes to effectively adapt, resulting in corrosion and cracking of some pipe bodies. At the same time, traditional plastic pipes are mostly connected by single hot melting and adhesives, so the situation of corrosion at the pipe orifice joints is more likely to occur. Therefore, there is an urgent need for a polyethylene composite drain pipe. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Referring to Figures 1-5 , a polyethylene composite material drain pipe includes a composite pipe 1. Mating interfaces one 6 and mating interfaces two 61 are respectively provided at both ends of the composite pipe 1. Hot-melt wedge-shaped ring gaskets 21 are embedded and installed on both the mating interfaces one 6 and the mating interfaces two 61, and an embedded bushing 4 is provided at one end of the mating interface two 61. One end of the embedded bushing 4 is correspondingly locked and clamped with the locking groove 7 opened on the inner wall of the mating interface one 6 through a special-shaped clamping block 5;
[0022] Further, the composite pipe 1 includes an outer pipe 101, an inner pipe 102, a steel mesh reinforcement layer 103, and a composite filling layer 104. The outer side of the inner pipe 102 is sequentially connected with the steel mesh reinforcement layer 103, the composite filling layer 104, and the outer pipe 101.
[0023] Further, the hot-melt wedge-shaped ring gaskets 21 provided on the docking interface one 6 and the docking interface two 61 are in opposite orientations. By setting the hot-melt wedge-shaped ring gaskets 21 in opposite directions, when connecting the pipe fittings, effective locking and clamping can be achieved through the wedge blocks, and hot-melt treatment can be performed on them later to ensure the connection stability.
[0024] Further, the embedded bushing 4 expands outwards. When the embedded bushing 4 is connected to the pipe fitting by caulking, the expanded bushing can provide better locking performance.
[0025] Further, a triangular support cavity 3 is provided on one side of the inner wall of the docking interface one 6, and a plurality of locking grooves 7 are provided on the side away from the triangular support cavity 3. The locking grooves 7 and the special-shaped clamping blocks 5 are mutually clamped structures.
[0026] Further, a special-shaped clamping block 5 is provided on one side of the bottom of the embedded bushing 4, and a pressing block 51 is provided at one end of the special-shaped clamping block 5. The pressing block 51 expands outwards.
[0027] Further, a convex ring 41 is provided on the outer side of the embedded bushing 4. When connecting the composite pipes, the convex ring 41 can be pressed and clamped with the triangular support cavity 3 to ensure the connection stability between the pipe fittings.
[0028] In this embodiment, the composite pipe 1 is composed of structures such as polyethylene material, composite filling layer 104, and steel mesh reinforcement layer 103. During its use, its corrosion resistance is stronger, and the overall strength of the pipe fitting is higher. Compared with traditional plastic pipes, this mechanism can effectively avoid water leakage and corrosion at joints such as pipe fittings and pipe seams.
[0029] At the same time, during the actual use process, hot-melt wedge-shaped ring gaskets 21 in opposite directions are respectively provided on the docking interface one 6 and the docking interface two 61. When connecting the pipe fittings, effective locking and clamping can be achieved through the wedge blocks, and hot-melt treatment can be performed on them later to ensure the connection stability; when connecting the pipe fittings, the outward-expanding embedded bushing 4 is inserted into another composite pipe 1 to be installed. The inner ring bushing 4 presses against its inner wall, and by continuously pressing and rotating the docking interface two 61, the embedded bushing 4 is completely inserted into the docking interface one 6. Under the rotation effect, the hot-melt wedge-shaped ring gaskets 21 are locked with each other, and the special-shaped clamping blocks 5 are clamped into the locking grooves 7. Since a pressing block 51 is provided on the other side of the special-shaped clamping block 5, the pressing block 51 can effectively achieve the reverse stop function. At the same time, with the pressing and clamping of the convex ring 41 and the triangular support cavity 3, the connection tightness can be further improved.
[0030] Meanwhile, the hot-melt wedge-shaped ring gaskets 21 are locked to each other and connected by hot melting, thereby improving the connection sealing performance and stability.
[0031] Meanwhile, the inner ring bushing 4 can effectively increase the sealing performance and integrity of the pipe fitting connection and avoid the possibility of leakage at the pipe joint.
[0032] It should be noted that the outer pipe 101, the inner pipe 102, and the embedded bushing 4 are all made of polyethylene material.
[0033] It should be noted that the composite filling layer 104 is made of nano-silica.
[0034] In the present utility model, the composite pipe 1 enhances the overall performance of the composite pipe through structures such as the polyethylene material, the composite filling layer 104, and the steel mesh reinforcement layer 103, effectively improves its anti-corrosion performance, ensures its various usage performances, and can effectively increase the stability of the pipe fitting during connection through components such as the hot-melt wedge-shaped ring gaskets 21 and the embedded bushing 4 provided on the interface one 6 and the interface two 61, avoiding the possibility of corrosion and water leakage at the joint, effectively improving the use strength and service life of the pipe body, and ensuring the stability of the medium transportation.
[0035] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
