Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to an enhanced structured-wall winding pipe. Background Art

[0002] The enhanced structured-wall winding pipe is a special-shaped structured-wall pipe made of high-molecular materials such as high-density polyethylene (HDPE) as the main raw material through a hot-state winding forming process. This pipe has the advantages of light weight, strong pressure-bearing capacity, high interface quality, long service life, corrosion resistance, high ring stiffness, and convenient construction, and is widely used in projects such as urban water supply, drainage, long-distance water conveyance, and farmland water conservancy irrigation.

[0003] At present, the existing winding pipe structure can refer to a double-high corrugated winding pipe disclosed in the Chinese utility model patent with the patent application number 202420760210.X. This winding pipe improves the ring stiffness and support performance of the pipe wall by setting outer rib supports on both sides of the bottom plate. However, in this structure, since the bottom plate is a single-layer structure, the bending resistance of the pipe is poor, and the bottom plate is prone to bending deformation when subjected to bending stress; even if an arc-shaped protrusion is added in the middle of the bottom plate, there is a gap between the two ends of the arc-shaped protrusion and the outer rib support. When the pipe bends, the bottom plate at the gap will still be deformed due to extrusion or stretching, and the structure is relatively unstable; in addition, the adjacent two groups of outer rib supports are connected by a hot-melt coating connection method, and this connection method cannot ensure the connection stability and is prone to cracking, resulting in pipe leakage. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an enhanced structured-wall winding pipe.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] The enhanced structured-wall winding pipe includes a pipe wall profile. The pipe wall profile is spirally wound along the cross-sectional direction, and adjacent turns of the pipe wall profile are connected by a connecting glue to form a pipe body. The pipe wall profile includes a horizontally arranged bottom plate and vertically arranged support plates on both sides of the bottom plate. The two support plates on both sides are symmetrical to each other. The bottom plate includes an inner layer plate and an outer layer plate arranged at intervals. A first support rib is also provided in the middle of the bottom plate to support between the inner layer plate and the outer layer plate. The tops of the two support plates on both sides extend obliquely downward inward to form second support ribs, and the extending ends of the two second support ribs are respectively connected to both sides of the outer layer plate to form a support.

[0007] In the utility model, serrated structures are provided on the outer sides of the two support plates on both sides, and the serrated structures are tightly connected to the connecting glue.

[0008] In the present utility model, the connecting glue is PVC glue. Both sides of the connecting glue are embedded into the sawtooth structure to form a stable connection, and the sawtooth structure is a rectangular groove structure; or a dovetail groove structure. The thickness of the connecting glue is 5 mm - 7 mm.

[0009] In the present utility model, after the pipe wall profiles are spirally wound, adjacent two support plates form a corrugated structure on the pipe body. A first steel wire strip for improving the ring stiffness of the pipe body is further provided at the top of the corrugated structure. The first steel wire strip is spirally wound along the corrugated structure. A covering layer is further provided at the top of the corrugated structure, and the covering layer covers the first steel wire strip and is tightly connected to the corrugated structure.

[0010] Furthermore, sealant is provided at the joint of the inner sides of adjacent two turns of the pipe wall profiles, and the sealant extends and adheres along the joint direction.

[0011] In the present utility model, second steel wire strips are respectively embedded at the joints of the bottoms of the two support plates on both sides and the bottom plate, and at the joints of the second support ribs and the bottom plate. The second steel wire strips extend along the winding direction of the pipe wall profiles.

[0012] In the present utility model, a protective layer is further covered on the outer side of the pipe wall profiles, and the protective layer adheres to the outer sides of the outer layer plate and the second support ribs.

[0013] The present utility model has the following advantages and beneficial effects:

[0014] By designing the bottom plate as a double-layer structure and arranging a first support rib between the inner layer plate and the outer layer plate in the middle of the bottom plate, the double-layer bottom plate has high compressive performance. Cooperating with the first support rib in the middle can also greatly improve the bending resistance performance. When the pipe is subjected to bending stress, the first support rib can tightly pull the inner layer plate and the outer layer plate, thereby improving the structural stability. In addition, second support ribs extending inward are provided on the support plates on both sides of the bottom plate, and the extending ends of the second support ribs are connected to both ends of the outer layer plate to form a support. When the pipe bends, the bending stress received on the bottom plate can be transmitted to the support plates through the second support ribs, further improving the bending resistance performance and making the overall performance of the pipe improved;

[0015] Adjacent two turns of the pipe wall profiles are connected by connecting glue, and a sawtooth structure for improving the contact surface is provided on the outer side of the support plate. The pipe wall profiles are tightly connected to the connecting glue through the sawtooth structure, avoiding the possibility of connection cracking and improving the connection stability.

[0022] As Figures 1 to 2 shown, this embodiment discloses an enhanced structural wall winding pipe, including a pipe wall profile 1. The pipe wall profile 1 is spirally wound along the cross-sectional direction. At the same time, adjacent turns of the pipe wall profile 1 are connected by a connecting glue 2 to form a pipe body. The pipe wall profile 1 includes a horizontally arranged bottom plate 11 and vertically and symmetrically arranged support plates 12 on both sides of the bottom plate 11. The bottom plate 11 includes an inner layer plate 111 and an outer layer plate 112 arranged at intervals. A first support rib 113 is further provided in the middle of the bottom plate 11 to support between the inner layer plate 111 and the outer layer plate 112. Second support ribs 13 extend obliquely downward inward from the tops of the support plates 12 on both sides. The extending ends of the second support ribs 13 on both sides are respectively connected to both sides of the outer layer plate 112 to form a support. In order to improve the connection stability between adjacent turns of the pipe wall profile 1, serrated structures 121 are provided on the outer sides of the support plates 12 on both sides. The serrated structures 121 are closely connected to the connecting glue 2. The serrated structures 121 can increase the connection area of the support plates 12 and improve the connection strength.

[0023] In this embodiment, the connecting glue 2 is PVC glue. When in a molten state, both sides of the connecting glue 2 are embedded into the serrated structure 121. When the connecting glue 2 dries and cures, a stable connection can be formed. Specifically, the serrated structure 121 is a rectangular groove structure; or a dovetail groove structure; or other structures that can improve the surface contact area. The thickness of the connecting glue 2 is 5 mm - 7 mm. By embedding the connecting glue 2 into the serrated structure 121, a pulling effect can be formed, improving the connection stability and the bending strength at the same time.

[0024] In this embodiment, after the pipe wall profile 1 is helically wound, adjacent two support plates 12 form a corrugated structure 3 on the pipe body. At the top of the corrugated structure 3, there is also a first steel wire strip 14 for improving the ring stiffness of the pipe body. The first steel wire strip 14 is helically wound along the corrugated structure 3. In order to fix the first steel wire strip 14, there is also a covering layer 4 at the top of the corrugated structure 3. After covering the first steel wire strip 14, the covering layer 4 is tightly connected to the corrugated structure 3.

[0025] Furthermore, in order to prevent the liquid inside the pipe body from affecting the connection between the connecting glue 2 and the support plate 12, there is also a sealing glue 5 at the joint on the inner side of adjacent two turns of the pipe wall profile 1. The sealing glue 5 extends and adheres along the joint direction.

[0026] In this embodiment, in order to improve the overall ring stiffness of the pipe wall profile 1, second steel wire strips 15 are respectively embedded at the joints between the bottoms of the two side support plates 12 and the bottom plate 11, and at the joints between the second support ribs 13 and the bottom plate 11. The second steel wire strips 15 extend along the winding direction of the pipe wall profile 1. Specifically, the second steel wire strips 15 are extruded and formed together with the pipe wall profile 1.

[0027] In this embodiment, the outer side of the pipe wall profile 1 is also covered with a protective layer 6. The protective layer 6 adheres to the outer side of the outer layer plate 112 and the outer side of the second support ribs 13. The protective layer 6 is made of resin material, and pigments can also be added to the protective layer 6 to change the color of the pipe body and improve the recognition.

Those skilled in the technical field to which the present invention belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them. As long as it does not deviate from the content of this specification of the present invention or exceed the scope defined by this claim book, it should fall within the protection scope of the present invention.
