Description

Technical Field

[0003] In municipal drainage and sewage projects, since the pipes need to be buried underground, higher requirements are placed on the ring stiffness and ring flexibility of the pipes. The current PE corrugated pipes are used more and more widely in municipal projects due to their lightness and durability. However, when damaged by ground subsidence and protrusions, the troughs of the corrugated pipes are made of two layers of pipe walls glued together and have no three-dimensional stiffness, and they often break and break. Utility Model Content

[0004] The utility model aims to provide a PE inner rib reinforced corrugated pipe, which is used to solve the problem of fracture and breakage caused by the lack of three-dimensional rigidity at the trough position of the corrugated pipe.

[0007] Furthermore, ribs perpendicular to the corrugated cavity are arranged in the corrugated cavity, and the ribs are distributed in the corrugated cavity in a circular array.

[0008] Furthermore, the mesh belt is provided with honeycomb holes arranged in an array.

[0009] Furthermore, straight sections are provided on the outer tube walls on both sides of the corrugated cavity.

[0010] Furthermore, the ribs are fixedly connected to the outer tube wall and the inner tube wall respectively.

[0011] Furthermore, the spacing between the ribs is smaller than the height of the corrugated cavity.

[0012] The utility model has the following beneficial effects: the PE inner rib reinforced corrugated pipe described in the present application adopts a three-dimensional mesh support belt to hold the two layers of pipe wall apart, and the distance between the two layers of pipe wall is increased so that pressure or weak tension is formed on the inner wall to prevent it from being torn. The mesh support belt is equivalent to increasing the wall thickness at the trough position, thereby increasing the stiffness at the trough position. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] (1-outer tube wall, 2-inner tube wall, 3-corrugated cavity, 4-mesh belt, 5-rib plate, 6-honeycomb hole) DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0018] like Figures 1 to 3 In the embodiment of the PE inner rib reinforced corrugated pipe of the utility model shown, the PE inner rib reinforced corrugated pipe includes a pipe body, the pipe body includes an outer pipe wall 1 and an inner pipe wall 2, a corrugated cavity 3 formed by stacking the outer pipe walls 1 is provided on the pipe body, a concave trough is formed in the middle of the two corrugated cavities 3, a mesh belt 4 is provided between the outer pipe wall 1 and the inner pipe wall 2 at the trough, and the two sides of the mesh belt 4 are fixedly connected to the inner and outer pipe walls respectively.

[0019] Specifically, the inner and outer walls of the existing corrugated pipe are tightly attached at the trough. When bending caused by settlement occurs, the inner and outer walls are simultaneously tensile and compressed. The rigidity is very small and the material properties cannot be fully utilized. By increasing the spacing between the inner and outer walls, the tensile strength of the outer wall 1 can be effectively exerted to resist the pulling force when bending occurs, and the inner wall 2 is subjected to pressure or weak tension to avoid damage. Adding a mesh belt 4 between the inner and outer walls can form a spatial skeleton, which produces greater rigidity here, thereby improving the crack resistance and breakage resistance of the trough.

[0020] In one embodiment of the present application, preferably, ribs 5 perpendicular to the corrugated cavity 3 are provided in the corrugated cavity 3 , and the ribs 5 are distributed in the corrugated cavity 3 in a circular array to improve the ring stiffness of the corrugated cavity 3 .

[0021] In one embodiment of the present application, preferably, the mesh belt 4 is provided with honeycomb holes 6 arranged in an array, so as to improve the overall stiffness at the trough and reduce the weight of the pipe, thereby saving resources.

[0022] In one embodiment of the present application, preferably, the outer tube walls 1 on both sides of the corrugated cavity 3 are provided with straight sections for improving the ring stiffness of the outer tube walls 1 at the corrugated cavity.

[0023] In one embodiment of the present application, preferably, the ribs 5 are fixedly connected to the outer tube wall 1 and the inner tube wall 2 respectively, so as to increase the longitudinal tension of the inner tube wall 2 .

[0024] In one embodiment of the present application, preferably, the spacing between the ribs 5 is smaller than the height of the corrugated cavity 3, so that the higher the corrugated cavity 3 is, the greater the density of the ribs 5 is, so that the rigidity of the corrugated cavity 3 is guaranteed.

[0025] To sum up, the PE inner rib reinforced corrugated pipe in the above embodiment of the utility model, specifically, when external force occurs during pipe laying, the ribs 5 in the corrugated cavity 3 and the straight section of the outer pipe wall 1 at the corrugated cavity 3 ensure the ring stiffness of the pipe to avoid being flattened, and when the pipe body is bent and pulled, the mesh belt 4 at the trough of the inner and outer pipe walls 1 supports the outer pipe wall 1, and the tension increases, and the inner pipe wall 2 is subjected to pressure or weak pressure. Since the corrugated cavity 3 formed by the stacking of the outer pipe walls 1 can resist part of the tension, the inner pipe wall 2 is subjected to pressure or weak tension to avoid damage, and the support of the mesh belt 4 in the honeycomb pores effectively improves the overall stiffness at the trough, avoids deformation at the trough, and improves the crack resistance and breakage resistance at the trough.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
