Description

Technical Field

[0001] This utility model relates to the field of buried pipe technology, specifically to a multi-section reinforced corrugated pipe with combined reinforcing ribs. Background Technology

[0002] Corrugated pipes are a type of pipe with an annular outer wall and a smooth inner wall. The annular corrugated structure of the outer wall enhances the ring stiffness of the pipe, thereby increasing its resistance to soil load. It also has good soil action properties and is widely used in drainage projects, where it can be buried underground as a drainage pipe.

[0003] For example, Chinese patent application number 201820924332.2, published on January 8, 2019, discloses an FRPE multi-rib reinforced double-layer double-anti-wound corrugated pipe, which is formed by stacking and spirally winding at least two types of winding units and then fused together with molten adhesive. The corrugated pipe includes a cylindrical pipe wall and hollow reinforcing ribs spirally distributed on the outer surface of the pipe wall, with a closed outer cavity formed between the hollow reinforcing ribs. The winding unit includes a base and protruding pipe walls at both ends of the base with closed cavities. When the units are stacked, the overlapping parts of the protruding tube walls are fused together with molten adhesive. When the winding unit is spirally wound, the outer edge of the protruding tube wall is fused together with molten adhesive, and the fused position forms a reinforcing rib inside the hollow reinforcing rib. When the winding unit is spirally wound, the outer sides of the adjacent protruding tube walls are fused together with molten adhesive. After fusion, a hollow reinforcing rib with internal reinforcing ribs is formed to improve the overall ring stiffness of the bellows. The stacking of winding units makes the winding unit form an outer cavity at the position of the substrate, thereby improving the ring stiffness at the trough of the bellows and improving the ring stiffness of the weak parts of the bellows.

[0004] The aforementioned literature addresses the safety hazards and bacterial growth issues in the weak points of corrugated pipes by adding outer wall reinforcing ribs and an antibacterial underlayer at the troughs of the corrugated pipe. However, during application, the pipe wall may support irregular loads. If only the curved reinforcing ribs are used for support, the overall rigidity of the corrugated pipe will be poor, which may damage the pipe wall structure. Utility Model Content

[0005] The purpose of this invention is to provide a multi-section reinforcing rib combination reinforced bellows, in which reinforcing ribs of different shapes are wrapped around the bellows wall to improve the ring stiffness of the bellows and meet the requirements for supporting irregular loads.

[0006] To achieve the above objectives, a multi-section reinforcing rib composite reinforced corrugated pipe is provided, comprising a corrugated pipe body and one or more reinforcing rib groups disposed on the outer wall of the corrugated pipe body. Each reinforcing rib group includes reinforcing ribs with cross-sectional shapes of plum blossom, polygon, and circle. The arrangement of reinforcing ribs with different cross-sectional shapes in adjacent reinforcing rib groups is the same or different. The height of different reinforcing ribs in the same reinforcing rib group is the same.

[0007] The above configuration involves setting one or more sets of reinforcing ribs on the outer wall of the bellows body, with reinforcing ribs of different shapes arranged in the sets. The arrangement order of the reinforcing ribs of different shapes in adjacent sets may be the same or different. This creates convex reinforcing ribs of different shapes on the outer wall of the bellows body. The different shapes of the reinforcing ribs, which are wrapped around the outer wall of the bellows body, can cope with the force of irregular external loads on the bellows, thereby improving the support matching degree between the overall outer wall of the bellows and the irregular external loads, and thus meeting the overall ring stiffness requirements of the bellows for bearing irregular loads.

[0008] Furthermore, the reinforcing rib group is arranged in the following ways: with the plum blossom-shaped reinforcing rib as the reference center and the polygonal reinforcing rib and the circular reinforcing rib are respectively located on both sides of the plum blossom-shaped reinforcing rib; or with the polygonal reinforcing rib as the reference center and the plum blossom-shaped reinforcing rib and the circular reinforcing rib are respectively located on both sides of the polygonal reinforcing rib; or with the circular reinforcing rib as the reference center and the polygonal reinforcing rib and the plum blossom-shaped reinforcing rib are respectively located on both sides of the circular reinforcing rib.

[0009] The above settings allow for the design of different cross-sectional shapes of reinforcing ribs in the reinforcing rib group according to the irregular loads that the bellows needs to bear, thereby ensuring that the overall ring stiffness of the bellows meets the requirements of the irregular loads it bears.

[0010] Furthermore, when the irregular load on the outer wall of the bellows body is the same at the position corresponding to the adjacent reinforcing rib group, the reinforcing ribs with different cross-sectional shapes in the adjacent reinforcing rib groups are arranged in the same way.

[0011] The above setup can address the irregular but identical loads that the bellows needs to bear at different locations by using the same arrangement of the reinforcing ribs in different adjacent reinforcing rib groups.

[0012] Furthermore, when the irregular loads on the outer wall of the bellows body and at the positions corresponding to adjacent reinforcing rib groups are different, the arrangement of reinforcing ribs with different cross-sectional shapes in adjacent reinforcing rib groups is different.

[0013] The above configuration can address the irregular loads that the bellows needs to bear at different locations by using different arrangements of the reinforcing ribs in different adjacent reinforcing rib groups, thereby meeting the ring stiffness requirements at different locations on the bellows.

[0014] Furthermore, the polygonal reinforcing ribs include reinforcing ribs with hexagonal or greater shapes.

[0015] The above settings can meet the ring stiffness requirements of the outer wall of the bellows body to support irregular external loads.

[0016] Furthermore, a first gap is provided between adjacent reinforcing rib groups.

[0017] The above configuration facilitates the winding of reinforcing ribs onto the outer wall of the corrugated pipe body, making production easier.

[0018] Furthermore, there is a second gap between adjacent reinforcing ribs in the reinforcing rib group, and the second gap is smaller than the first gap.

[0019] The above configuration allows for the filling of soil and rocks in both the first and second gaps, which better prevents axial movement of the corrugated pipe and enables it to withstand irregular and identical loads. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] Example 1.

[0036] like Figure 1-9 As shown, a multi-section reinforcing rib composite reinforced bellows includes a bellows body 1 and one or more reinforcing rib groups 2 disposed on the outer wall of the bellows body 1. Each reinforcing rib group 2 includes a plum blossom-shaped reinforcing rib 21, a polygonal reinforcing rib 22, and a circular reinforcing rib 23. Figure 10 As shown, the reinforcing rib group 2 can be arranged with the quincunx-shaped reinforcing rib 21 as the reference center and the polygonal reinforcing rib 22 and the circular reinforcing rib 23 located on both sides of the quincunx-shaped reinforcing rib 21, as shown. Figure 11 As shown, the reinforcing rib group 2 can also be arranged with the polygonal reinforcing rib 22 as the reference center and the quincunx-shaped reinforcing ribs 21 and the circular reinforcing ribs 23 located on both sides of the polygonal reinforcing rib 22, as shown. Figure 1 and Figure 2As shown, the reinforcing rib group 2 can also be arranged with the circular reinforcing rib 23 as the reference center and the polygonal reinforcing ribs 22 and the quincunx-shaped reinforcing ribs 21 located on both sides of the circular reinforcing rib 23. The arrangement of the quincunx-shaped reinforcing rib 21 as the reference center with the polygonal reinforcing ribs 22 and the circular reinforcing ribs 23 located on both sides of the quincunx-shaped reinforcing rib 21 includes "polygonal reinforcing rib 22, quincunx-shaped reinforcing rib 21, circular reinforcing rib 23" and "circular reinforcing rib 23, quincunx-shaped reinforcing rib 21, polygonal reinforcing rib 22" arranged sequentially along the axial direction X; the arrangement of the polygonal reinforcing rib 22 as the reference center with the quincunx-shaped reinforcing ribs 21 and the circular reinforcing ribs 23 located on both sides of the polygonal reinforcing rib 22 includes "quincunx-shaped reinforcing rib 21, polygonal reinforcing rib 22, circular reinforcing rib 23" and "circular reinforcing rib 23" arranged sequentially along the axial direction X. "Circular reinforcing rib 23, polygonal reinforcing rib 22, and plum blossom-shaped reinforcing rib 21"; with the circular reinforcing rib 23 as the reference center and the polygonal reinforcing rib 22 and plum blossom-shaped reinforcing rib 21 located on either side of the circular reinforcing rib 23, the arrangement includes "polygonal reinforcing rib 22, circular reinforcing rib 23, plum blossom-shaped reinforcing rib 21" and "plump blossom-shaped reinforcing rib 21, circular reinforcing rib 23, polygonal reinforcing rib 22" arranged sequentially in the axial direction X. This allows for the design of reinforcing rib arrangements with different cross-sectional shapes in the reinforcing rib group 2 according to the irregular loads required to be borne by the bellows, thus ensuring that the overall ring stiffness of the bellows meets the requirements for bearing irregular loads. In this utility model, "irregular load" refers to... Figure 3 As shown, the forces F1, F2, and F3 applied to different reinforcing ribs in the same reinforcing rib group are different, and / or the forces applied to the same reinforcing ribs in the circumferential direction are different, thus forming irregular loads.

[0037] In this embodiment, as Figure 4 As shown, the plum blossom-shaped reinforcing rib 21 includes a circular ring 211 and a plurality of circumferentially distributed convex arcs 212 disposed on the outer wall of the circular ring 211, with gaps between adjacent convex arcs 212. Figure 8 As shown, the polygonal reinforcing rib 22 includes reinforcing ribs with hexagonal or more shapes. In this embodiment, "polygonal" refers to the outer contour of the reinforcing rib being polygonal; in this embodiment, it is a hexagonal reinforcing rib. Figure 7 As shown, circular reinforcing rib 23 refers to a reinforcing rib that is circular in shape.

[0038] In this embodiment, the plum blossom-shaped reinforcing ribs 21, polygonal reinforcing ribs 22, and circular reinforcing ribs 23 in the same group of reinforcing ribs are in contact to form an integral whole. The reinforcing rib group 2 can be integrally formed with the corrugated pipe body 1, or it can be separately formed and then connected to the corrugated pipe body 1 to form a multi-section reinforcing rib combination type reinforced corrugated pipe.

[0039] like Figure 5As shown, when the irregular load on the outer wall of the bellows body 1 and at the position corresponding to the adjacent reinforcing rib group 2 is the same, that is, when F0=F10, the arrangement of the reinforcing ribs with different cross-sectional shapes in the adjacent reinforcing rib group 2 is the same; while when the irregular load on the outer wall of the bellows body 1 and at the position corresponding to the adjacent reinforcing rib group 2 is different, that is, when F0≠F10, the arrangement of the reinforcing ribs with different cross-sectional shapes in the adjacent reinforcing rib group 2 is different. In this way, the different arrangements of the reinforcing ribs in the different adjacent reinforcing rib groups 2 can be used to deal with the different irregular loads that the bellows needs to bear at different positions, so as to meet the ring stiffness requirements at different positions on the bellows.

[0040] In this embodiment, the heights of different reinforcing ribs in the same reinforcing rib group 2 are the same, such as... Figures 6 to 8 As shown, "the height of different reinforcing ribs in the same reinforcing rib group 2 is the same" means that the outer contour circle of the plum blossom-shaped reinforcing rib 21, the outer circumference circle of the polygonal reinforcing rib 22, and the outer contour diameter of the circular reinforcing rib 23 are the same. A first gap 24 is provided between different adjacent reinforcing rib groups 2, which makes it easy for the reinforcing rib group 2 to be wound on the outer wall of the corrugated pipe body 1 and easy to produce.

[0041] Example 2.

[0042] like Figure 12 and Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the plum blossom-shaped reinforcing ribs 21, polygonal reinforcing ribs 22, and circular reinforcing ribs 23 are in contact and fitted together at adjacent positions, while in Embodiment 2, there is a second gap 20 between adjacent reinforcing ribs in the reinforcing rib group. That is, there is a second gap 20 between adjacent plum blossom-shaped reinforcing ribs 21, polygonal reinforcing ribs 22, and circular reinforcing ribs 23, and the second gap 20 is smaller than the first gap 24. This structure can fill soil and stones in both the first and second gaps, which can better prevent the axial movement of the corrugated pipe, and at the same time can bear irregular and uniform loads.

[0043] Example 3.

[0044] like Figure 14 As shown, in Embodiment 3, based on Embodiments 1 and 2, a socket 100 and a spigot 200 are respectively provided at both ends of the corrugated pipe body 1 to facilitate the connection between adjacent multi-section reinforcing rib combination reinforced corrugated pipes.
