[0025] In related technologies, existing drainage and sewage pipe structures mostly use concrete pipes, which generally have poor corrosion resistance and require improvement. Therefore, the technical solution of this application was developed, and is described below in conjunction with... Figures 1 to 3 To elaborate.

[0026] Example 1 like Figures 1 to 3 As shown, the composite drainage pipe of this utility model includes a pipe body 1, and the pipe body 1 is provided with an inner lining plate 11 and a concrete layer 12 from the inside to the outside.

[0027] like Figure 1 and Figure 2 As shown, the inner lining plate 11 is made of PE board, and the inner lining plate 11 is connected to the inner wall of the concrete layer 12 by a number of composite hooks 2.

[0028] like Figure 3 As shown, the composite hook 2 includes a hook body 21 and a first covering layer 22, the first covering layer 22 covering the end of the hook body 21, as shown. Figure 2 As shown, the first covering layer 22 is made of the same material as the inner lining plate 11 and is heat-fused together, and the hanging nail body 21 is embedded in the concrete layer 12.

[0029] like Figure 2 As shown, the concrete layer 12 is provided with at least one layer of reinforcing mesh 13, which is a fiber mesh or a steel wire mesh; the end of the hanging nail body 21 is connected to the reinforcing mesh 13 by wire binding, for example by iron wire binding or by nylon rope binding; or the end of the hanging nail body 21 is welded to the steel wire mesh.

[0030] like Figure 2As shown, the pipe body 1 also includes an end plate 14, which is disposed at the end of the concrete layer 12 and is connected to the inner lining plate 11. The inner lining plate 11 and the end plate 14 are made of the same material and are heat-fused together. The end plate 14 is connected to the end of the concrete layer 12 by a plurality of composite hooks 2, and the first covering layer 22 is heat-fused to the end plate 14. The end plate 14 includes a hook portion 141, which wraps around the end of the outer wall of the concrete layer 12.

[0031] In some alternative embodiments, adjacent tubes 1 are connected by heat shrink sleeves or joints.

[0032] In this embodiment, the inner lining plate 11 is made of PE material, which has the advantages of being non-toxic and odorless, not polluting water quality, corrosion resistant, long service life, low frictional resistance, not easy to scale, and easy to connect. However, the production of large-diameter PE pipes is very difficult, the equipment is expensive and not easy to operate, the pipe yield is low, the ring stiffness is low and the cost is high. Therefore, this application uses PE as the inner lining plate 11, and uses the concrete layer 12 of the pipe body 1 as a skeleton to connect the inner lining plate 11 to the inner wall of the concrete layer 12 to form a composite drainage pipe, which combines the advantages of PE pipe and the concrete layer 12. In addition, the composite hook 2 can effectively connect the inner lining plate 11 to the concrete layer 12 into a whole. Specifically, the principle of the composite hook 2 is similar to that of dish soap. Dish soap has both hydrophilic and oleophilic groups, which can combine oil and water. The composite hook 2 has both the hook body 21 and the first covering layer 22. The hook body 21 is easy to connect to the concrete, and the first covering layer 22 is easy to weld to the inner lining plate 11. Therefore, the inner lining plate 11 and the concrete layer 12 can be connected into a whole by the composite hook 2.

[0033] In this embodiment, based on the concrete layer 12 as the skeleton, the diameter of the pipe body 1 is 1000mm~4000mm, for example 1000mm, 1200mm, 1400mm, 1500mm, 1600mm, 1800mm, 2000mm, 2200mm, 2400mm, 2600mm, 2800mm, 3000mm, 3200mm, 3400mm, 3600mm, 3800mm, 4000mm; it has high ring stiffness, reaching SN16 or above; it can be used as a long-distance drainage pipe, sewage pipe or cable corridor; and it can be constructed using trenchless methods.

[0034] This embodiment describes a composite drainage pipe. An inner lining plate 11 is connected to the inner wall of the concrete layer 12 of the pipe body 1. The inner lining plate 11 is made of PE board, which has good corrosion resistance, does not scale, and extends the service life of the concrete pipe. The pipe body 1, in turn, provides reliable strength to the inner lining plate 11, making it less prone to damage. Simultaneously, the inner lining plate 11 and the concrete layer 12 are connected by composite hooks 2. The hook body 21 is similar to a shear stud, wrapped and connected by the concrete layer 12. The first covering layer 22 is fused to the inner lining plate 11, making the connection between the inner lining plate 11 and the concrete layer 12 stable. The composite hooks 2 easily achieve the composite of different materials, resulting in a composite drainage pipe with good overall integrity.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
