Inner rib winding reinforced corrugated pipe

Abstract

The utility model relates to an inner rib winding reinforced corrugated pipe which is characterized in that a U-shaped wave strip spirally wound on the surface of a pipe body protects the pipe body, when the corrugated pipe is extruded by external force, the extrusion force reaches the U-shaped wave strip firstly, and the force is dispersed by the U-shaped wave strip and then is transmitted to the pipe body, so that the impact of the physical force of the pipe body is reduced, and the service life of the corrugated pipe is prolonged. When the U-shaped wave strip is extruded by force in different directions, extrusion force is transmitted to the vertical reinforcing rib closest to the extrusion force direction through the U-shaped wave strip, and then the vertical reinforcing rib extrudes the rhombic reinforcing rib, so that the rhombic reinforcing rib deforms in the first cavity, and the extrusion force is dispersed; the wave strips are still stably connected to the pipe body when deforming, and breakage caused by the fact that the pipe cannot deform is reduced.

Description

Technical Field

[0001] This utility model relates to the field of internally ribbed corrugated pipe technology, and in particular to an internally ribbed wound reinforced corrugated pipe. Background Technology

[0002] In many fields such as urban sewer pipes and drainage projects, reinforced plastic pipes are becoming increasingly used. Since there is no internal pressure in drainage pipes, in order to improve their resistance to external pressure and impact, inner ribs are wrapped around the outside of the pipe to increase their compressive strength.

[0003] The existing pipe has a single vertical reinforcing rib in the middle of the inner rib. When the inner rib is subjected to compression from different directions, the single vertical reinforcing rib cannot distribute the force well and cannot support the unreinforced areas, which can cause the pipe to crack and leak. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the aforementioned problems in the prior art, this utility model provides an internally ribbed reinforced corrugated pipe that can increase or decrease the support strength in the middle of the internal ribs, enabling the internally ribbed pipe to better support and protect itself when subjected to forces in different directions, thereby reducing the probability of pipe cracking.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A corrugated pipe with internal ribs and reinforced by spiral winding includes a pipe body and an internal rib tube assembly, wherein the internal rib tube assembly is spirally wound on the outer surface of the pipe body.

[0009] The inner rib tube assembly includes a U-shaped corrugation and several vertical and rhomboid reinforcing ribs. A first cavity is provided between the U-shaped corrugation and the tube body. The rhomboid reinforcing ribs are filled inside the first cavity. The rhomboid reinforcing ribs are connected to the inner wall of the first cavity and the inner wall of the tube body by several vertical reinforcing ribs.

[0010] Furthermore, a second cavity is provided in the middle of the rhomboid reinforcing rib.

[0011] Furthermore, the rhomboid reinforcing rib includes side A, side B, side C, and side D, with side A being parallel to side B and side C being parallel to side D.

[0012] Furthermore, one side of the U-shaped wave strip is designated as side E, the other side of the U-shaped wave strip is designated as side F, and side G is designated between side E and side F, with side E connected to side F via side G.

[0013] Furthermore, side A is parallel to side G.

[0014] Furthermore, side C is parallel to side E.

[0015] (III) Beneficial Effects

[0016] The beneficial effects of this utility model are as follows: The U-shaped corrugated strip spirally wound on the surface of the pipe body protects the pipe body. When the corrugated pipe is subjected to external pressure, the pressure first reaches the U-shaped corrugated strip. After the U-shaped corrugated strip disperses the force, it is transmitted to the pipe body, thereby reducing the impact of the force on the pipe body. When the U-shaped corrugated strip is subjected to pressure from forces in different directions, the pressure is transmitted through the U-shaped corrugated strip to the vertical reinforcing rib closest to the direction of the pressure. Subsequently, the vertical reinforcing rib compresses the diamond-shaped reinforcing rib, causing the diamond-shaped reinforcing rib to deform inside the first cavity, thereby dispersing the pressure. This allows the corrugated strip to remain stably connected to the pipe body when it deforms, reducing the risk of pipe cracking due to non-deformability. This increases or decreases the support strength in the middle of the inner rib, allowing the inner rib pipe to better support and protect itself when subjected to forces in different directions, thereby reducing the probability of pipe cracking.

[0022] Pipe body 1, U-shaped corrugation 2, diamond-shaped reinforcing rib 3, vertical reinforcing rib 4, side A 5, side B 6, side C 7, side D 8, side F 9, side E 10, side G 11, first cavity 12, second cavity 13. Detailed Implementation

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figures 1 to 4As shown, the present invention provides an internally ribbed reinforced corrugated pipe, comprising a pipe body 1 and an internally ribbed pipe assembly, wherein the internally ribbed pipe assembly is spirally wound on the outer surface of the pipe body 1.

[0025] The inner rib tube assembly includes a U-shaped corrugated strip 2 and several vertical reinforcing ribs 4 and rhomboid reinforcing ribs 3. A first cavity is provided between the U-shaped corrugated strip 2 and the tube body 1. The rhomboid reinforcing ribs 3 are filled inside the first cavity. The rhomboid reinforcing ribs 3 are connected to the inner wall of the first cavity and the inner wall of the tube body 1 by several vertical reinforcing ribs 4.

[0026] The working principle of this utility model is as follows: The U-shaped corrugated strip 2, spirally wound on the surface of the pipe body 1, protects the pipe body 1. When the corrugated pipe is squeezed by external force, the squeezing force first reaches the U-shaped corrugated strip 2. After the force is dispersed by the U-shaped corrugated strip 2, it is transmitted to the pipe body 1, thereby reducing the impact of the force on the pipe body 1. When the U-shaped corrugated strip 2 is squeezed by forces in different directions, the squeezing force is transmitted through the U-shaped corrugated strip 2 to the vertical reinforcing rib 4 closest to the direction of the squeezing force. Then, the vertical reinforcing rib 4 squeezes the rhomboid reinforcing rib 3, causing the rhomboid reinforcing rib 3 to deform inside the first cavity, thereby dispersing the squeezing force and ensuring that the corrugated strip remains stably connected to the pipe body when it deforms, reducing the cracking of the pipe due to its indeformability.

[0027] Furthermore, a second cavity is provided in the middle of the rhomboid reinforcing rib 3.

[0028] As can be seen from the above description, it is beneficial to reduce the material used in the processing of corrugated pipes, and to make the rhomboid reinforcing rib 3 deform better in the first cavity after being subjected to force.

[0029] Furthermore, the rhomboid reinforcing rib 3 includes side A 5, side B 6, side C 7 and side D 8, side A 5 is parallel to side B 6, and side C 7 is parallel to side D 8.

[0030] As can be seen from the above description, it is advantageous to use the rhomboid reinforcing rib 3 with a parallelogram shape to better disperse the compressive force, and the rhomboid reinforcing rib 3 with this shape can better deform under forces in different directions.

[0031] Furthermore, one side of the U-shaped wave strip 2 is set as E side 10, the other side of the U-shaped wave strip 2 is set as F side 9, and G side 11 is set between E side 10 and F side 9. E side 10 is connected to F side 9 through G side 11.

[0032] Furthermore, side A 5 is parallel to side G 11.

[0033] As can be seen from the above description, when the G side 11 is subjected to compressive force, it can be better transferred to the A side 5 through the adjacent vertical reinforcing rib 4, so that the A side 5 can disperse the compressive force along the A side 5 direction.

[0034] Furthermore, side C 7 is parallel to side E 10.

[0035] As can be seen from the above description, when side E10 receives compressive force, it can be better transferred to side C7 through the adjacent vertical reinforcing rib 4, so that side C7 can disperse the compressive force along the direction of side C7. Example 1

The rhomboid reinforcing ribs 3 are connected to the inner wall of the first cavity and the inner wall of the tube body 1 by several vertical reinforcing ribs 4.

[0038] The diamond-shaped reinforcing rib 3 has a second cavity in the middle;

[0039] The rhomboid reinforcing rib 3 includes side A 5, side B 6, side C 7 and side D 8, side A 5 is parallel to side B 6, and side C 7 is parallel to side D 8;
