Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and more specifically, to a double high-rib corrugated pipe. Background Technology

[0002] Currently, corrugated pipes are widely used in the field of drainage pipes due to their good flexibility, pressure resistance and corrosion resistance. With the continuous development of urban construction, higher requirements are being placed on the pressure resistance and stability of drainage pipes.

[0003] Traditional corrugated pipes have certain limitations in structural design and are difficult to meet the growing engineering demands. For example, in some large-scale municipal projects, the pipes need to withstand greater pressure from the soil above and ground traffic. If the pipes are not strong enough, they are prone to deformation or even rupture, which will affect the normal operation of the drainage system.

[0004] In view of this, the present invention proposes a double high-rib corrugated pipe. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a double high-rib corrugated pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-high-rib corrugated pipe, comprising an inner pipe, an outer pipe disposed outside the inner pipe, a plurality of distributed adjustment structures disposed on the outer pipe, the surface of the distributed adjustment structures being provided with a double-high-rib structure, the inner pipe being made of high-density polyethylene, the outer pipe being made of modified polypropylene, and a buffer cavity filled with elastic rubber particles being formed between the inner wall of the outer pipe and the outer wall of the inner pipe.

[0007] To facilitate the adjustment of the distance between several double-high-rib structures according to the length of the corrugated pipe, so that the pipeline can better adapt to the stress requirements under different working conditions, preferably, the distributed adjustment structure includes two guide grooves opened on the outer wall of the outer pipe, and several sliders are slidably installed inside the two guide grooves. Multiple positioning rings are provided on the surface of the outer pipe, and the sliders are fixedly installed on the inner wall of the corresponding positioning rings. Screws are provided at the connection between the positioning rings and the outer pipe, and they are connected by screws.

[0008] To further improve the compressive strength of the corrugated pipe, preferably, the double-rib structure includes several rib rings, which are respectively fixedly installed on the surface of corresponding positioning rings. The rib rings are hollow, and several reinforcing ribs are installed inside the rib rings. The number of reinforcing ribs is set to two sets, which are symmetrically distributed inside the rib rings. The two ends of the reinforcing ribs are respectively connected to the inner wall of the rib rings. A reinforcing block is fixedly installed at the top of the inner cavity of the rib rings, and a first arc-shaped elastic block is fixedly installed at the bottom of the reinforcing block. A second arc-shaped elastic block is fixedly installed at the bottom of the inner cavity of the rib rings. The first and second arc-shaped elastic blocks are symmetrically arranged, and their arc surfaces fit together. Both the first and second arc-shaped elastic blocks are made of polyurethane elastomer material.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. By setting up a distributed adjustment structure, the position and spacing of the double high-rib structure on the corrugated pipe can be flexibly adjusted according to different engineering needs and stress conditions, so as to achieve precise optimization of the mechanical properties of the pipeline, enabling the pipeline to maintain good pressure resistance and deformation resistance in complex environments, and improving the versatility and adaptability of the pipeline.

[0011] 2. By setting up a double-high rib structure, the reinforcing ribs inside the rib ring effectively enhance the circumferential strength and rigidity of the pipeline, enabling it to withstand greater external pressure, reducing the risk of deformation and rupture caused by pressure during use, and extending the service life of the pipeline. Moreover, the first and second arc-shaped elastic blocks in the inner cavity of the rib ring can be squeezed and deformed to absorb energy when the pipeline is impacted, playing a role in buffering and shock absorption, and reducing the damage of external impact force to the pipeline structure.

[0012] 3. The high-density polyethylene material of the inner tube ensures the safe and stable transportation of internal fluids due to its corrosion resistance, flexibility and chemical stability. The modified polypropylene material of the outer tube has high strength and rigidity to withstand external pressure, laying the foundation for its basic mechanical properties. At the same time, when the pipeline is subjected to external compression, impact or expansion and contraction due to temperature changes, the elastic rubber particles in the buffer cavity between the outer and inner tubes compress and rebound, absorbing and dispersing external forces and reducing the risk of pipeline damage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-3 The illustrated double-high-rib corrugated pipe includes an inner pipe 1 and an outer pipe 2 disposed outside the inner pipe 1. The outer pipe 2 is provided with a plurality of distributed adjustment structures, and the surface of the distributed adjustment structures is provided with double-high-rib structures. The inner pipe 1 is made of high-density polyethylene, and the outer pipe 2 is made of modified polypropylene. A buffer cavity filled with elastic rubber particles is formed between the inner wall of the outer pipe 2 and the outer wall of the inner pipe 1.

[0020] Specifically, in this structure, the inner tube 1 is made of high-density polyethylene, which has good corrosion resistance, flexibility and chemical stability, and can ensure safe and stable internal fluid transportation. The outer tube 2 is made of modified polypropylene, which has high strength and rigidity and can withstand external pressure, thus providing the corrugated pipe with basic mechanical properties and durability.

[0021] The buffer cavity between the inner wall of the outer pipe 2 and the outer wall of the inner pipe 1 is filled with elastic rubber particles. When the pipe is subjected to external pressure, impact or expansion and contraction due to temperature changes, the elastic rubber particles absorb and disperse external forces through their own compression and rebound deformation, reducing the direct effect of external forces on the inner and outer pipes 2, reducing the risk of pipe damage, and improving the overall buffering and energy absorption effect.

[0022] The distributed adjustment structure on the outer pipe 2 is used to adjust the position and spacing of several double high-rib structures according to the length of the corrugated pipe, so that the pipe can better adapt to different working conditions and optimize the mechanical distribution. The double high-rib structure can further improve the pressure resistance of the corrugated pipe.

[0023] In this embodiment, as shown in the appendix Figure 1 , 2As shown in Figure 3, the distributed adjustment structure includes two guide grooves 3 opened on the outer wall of the outer tube 2. Several sliders 4 are slidably installed inside the two guide grooves 3. Multiple positioning rings 5 ​​are provided on the surface of the outer tube 2. The sliders 4 are fixedly installed on the inner wall of the corresponding positioning rings 5. Screws 6 are provided at the connection between the positioning rings 5 ​​and the outer tube 2, and they are connected by the screws 6.

[0024] Specifically, in this structure, the guide groove 3 on the outer tube 2 provides a sliding track for the slider 4, allowing the slider 4 to move along the length of the guide groove 3, thus improving the flexibility of the position adjustment of the positioning ring 5. The slider 4 is fixed to the inner wall of the positioning ring 5, forming an integral part with the positioning ring 5. After the slider 4 is embedded in the guide groove 3, it can drive the positioning ring 5 to slide along the guide groove 3, thereby changing the distribution position of the positioning ring 5 in the axial direction of the pipe. Finally, the positioning ring 5 is connected and fixed to the outer tube 2 by the screw 6 to determine the final position of the positioning ring 5, thereby realizing the flexible adjustment of the double high rib structure distribution, allowing the pipe to better adapt to the stress requirements under different working conditions.

[0025] In this embodiment, as shown in the appendix Figure 1 , 3 As shown in Figure 4, the double-high rib structure includes several rib rings 7, which are fixedly installed on the surface of the corresponding positioning rings 5. The rib rings 7 are hollow, and several reinforcing ribs 8 are installed inside the rib rings 7. The number of reinforcing ribs 8 is set to two sets, and they are symmetrically distributed inside the rib rings 7. The two ends of the reinforcing ribs 8 are connected to the inner wall of the rib rings 7. A reinforcing block 9 is fixedly installed at the top of the inner cavity of the rib ring 7, and a first arc-shaped elastic block 10 is fixedly installed at the bottom of the reinforcing block 9. A second arc-shaped elastic block 11 is fixedly installed at the bottom of the inner cavity of the rib ring 7. The first arc-shaped elastic block 10 and the second arc-shaped elastic block 11 are symmetrically arranged, and their arc surfaces fit together. The first arc-shaped elastic block 10 and the second arc-shaped elastic block 11 are both made of polyurethane elastomer material.

[0026] Specifically, in this structure, several stiffening rings 7 are fixed on the surface of the corresponding positioning rings 5, providing an installation foundation and structural support for the entire double-high stiffening structure, ensuring the stability and integrity of the structure. The stiffening rings 7 are hollow and have two sets of symmetrically distributed reinforcing ribs 8 installed. The reinforcing ribs 8 are connected to the inner wall of the stiffening rings 7 to enhance the structural strength and rigidity of the stiffening rings 7, enabling the stiffening rings 7 to withstand greater pressure and external forces, and improving the overall compressive strength of the corrugated pipe.

[0027] When the stiffening ring 7 is subjected to external pressure, the reinforcing block 9 can further enhance the structural stability of the stiffening ring 7, while the first arc-shaped elastic block 10 and the second arc-shaped elastic block 11 are squeezed and deformed against each other. Through their own elastic deformation, they absorb and disperse the pressure, playing a role in buffering and shock absorption, and further improving the impact resistance and stability of the double high-stiffening structure.

[0028] Working principle of this utility model:

[0029] This application provides a double high-strength corrugated pipe. First, the high-density polyethylene material of the inner pipe 1 ensures the safe and stable transportation of internal fluids due to its corrosion resistance, flexibility and chemical stability. The modified polypropylene material of the outer pipe 2 has high strength and rigidity to withstand external pressure, laying the foundation for its basic mechanical properties. When the pipe is subjected to external extrusion, impact or expansion and contraction due to temperature changes, the elastic rubber particles in the buffer cavity between the outer pipe 2 and the inner pipe 1 compress and rebound, absorbing and dispersing external forces and reducing the risk of pipe damage.

[0030] Next, through the distributed adjustment structure composed of the guide groove 3, slider 4 and positioning ring 5 on the outer pipe 2, the position of the positioning ring 5 is flexibly adjusted according to the pipe length and stress requirements under different working conditions, which drives the double high rib structure to move, thereby realizing the flexible adjustment of the distribution of the double high rib structure and optimizing the mechanical distribution.

[0031] Finally, the rib ring 7 in the double high-rib structure is fixed to the positioning ring 5. The hollow structure is equipped with two sets of symmetrical reinforcing ribs 8 to enhance the compressive strength and evenly distribute the stress. When the rib ring 7 is subjected to external pressure, the reinforcing block 9 stabilizes the structure, and the first arc-shaped elastic block 10 and the second arc-shaped elastic block 11 are squeezed and deformed to buffer and reduce shock, further improving the overall compressive and impact resistance, and ensuring that the double high-rib corrugated pipe can operate stably under complex working conditions.

[0032] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
