Description

Technical Field

[0001] This utility model relates to the field of concrete drainage pipe technology, and in particular to a pressure-resistant concrete drainage pipe. Background Technology

[0002] Concrete drainage pipes are a type of pipe used in drainage systems. They are typically made of concrete, which has high strength and durability, and are commonly used in municipal drainage systems, road drainage systems, and building drainage systems.

[0003] For example, a Chinese patent discloses a concrete drainage pipe (publication number: CN216743209U). This pipe features a sealing mechanism installed on its surface. A movable plate can cut off the water flow through the pipe, allowing for easy control of flow and closure. It is convenient for practical use. Furthermore, anti-slip grooves on the pipe surface and connectors at both ends facilitate installation, making it easier to place the pipe into pre-dug trenches and connect it to other drainage pipes. The anti-slip grooves effectively prevent the pipe from slipping when lifted, enhancing safety. However, in actual use, this concrete drainage pipe is prone to deformation both internally and externally due to excessive load-bearing capacity, potentially leading to concrete detachment. This results in decreased lateral and vertical compressive strength, affecting its long-term use. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a pressure-resistant concrete drainage pipe, which solves the technical problem that existing concrete drainage pipes are prone to deformation inside and outside due to excessive load-bearing capacity in actual use, and even concrete spalling, resulting in a decrease in lateral and vertical compressive strength and affecting later use.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A pressure-resistant concrete drainage pipe includes an outer pipe body, wherein first reinforcing ribs are uniformly and equidistantly fixedly installed inside the outer pipe body, and horizontal bars are uniformly and equidistantly fixedly installed in the inner wall of the outer pipe body, and U-shaped bars are fixedly installed on the opposite ends of the four horizontal bars. Each of the four U-shaped strips has equally spaced circular grooves on its opposite ends.

[0006] Preferably, each of the four U-shaped strips is fixedly installed with a stress-relieving rib between each pair.

[0007] Preferably, an inner tube is provided inside the outer tube; The inner tube body is provided with a second reinforcing rib that is evenly and equidistantly fixed inside.

[0008] Preferably, connecting strips are evenly and equidistantly fixedly installed on the side wall of the inner tube.

[0009] Preferably, each of the four connecting strips has a strip-shaped groove on the side wall away from the inner tube.

[0010] Preferably, each of the four connecting strips has a through groove running through it. The four through slots are respectively connected to the four strip slots, and the horizontal bar and the U-shaped bar are respectively slidably embedded in the strip slots and the through slots.

[0011] Preferably, top columns are fixedly installed at equal intervals in the inner walls of the four through slots; Each of the top pillars is directly opposite each of the circular grooves.

[0012] (III) Beneficial Effects 1. Through the design of horizontal bars, U-shaped bars, stress relief ribs, strip grooves and through grooves, when the equipment is under stress, the horizontal bars and U-shaped bars will slide inside the strip grooves and through grooves. At this time, the U-shaped bars will cause the stress relief ribs fixed to them to undergo slight deformation, thereby relieving the pressure. The stress relief ribs will transmit the pressure to the two U-shaped bars adjacent to the pressure point. However, the U-shaped bars are limited, so the pressure will be dispersed. This allows the equipment to quickly disperse the pressure when it is under pressure during use, thereby enhancing the equipment's pressure resistance. Second, through the design of the U-shaped bar and the top column, when the U-shaped bar moves under force, it will come into contact with the top column, and the two will slide relative to each other. Friction will be generated under relative sliding, which can further dilute and disperse the pressure, thereby further enhancing the pressure resistance of the equipment. Attached Figure Description

[0016] This application provides a pressure-resistant concrete drainage pipe that effectively solves the problem that existing concrete drainage pipes are prone to deformation, even concrete spalling, due to excessive load-bearing capacity during long-term use. This leads to a decrease in lateral and vertical compressive strength, affecting later use. Through the design of horizontal bars, U-shaped bars, stress relief ribs, strip grooves, and through grooves, when the equipment is under stress, the horizontal bars and U-shaped bars slide inside the strip grooves and through grooves. At this time, the U-shaped bars will cause the stress relief ribs fixed to them to deform slightly, thereby relieving the pressure. The stress relief ribs will transmit the pressure to the two U-shaped bars adjacent to the pressure point. However, the U-shaped bars are limited, so the pressure is dispersed. This allows the equipment to quickly disperse pressure when under pressure during use, thereby enhancing the equipment's compressive strength.

[0017] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that existing concrete drainage pipes are prone to deformation inside and outside due to excessive load-bearing capacity during actual use, and even concrete spalling occurs, resulting in a decrease in lateral and vertical compressive strength and affecting later use. The overall idea is as follows: A pressure-resistant concrete drainage pipe includes an outer pipe body 11, with first reinforcing ribs 12 uniformly and equidistantly fixed inside the outer pipe body 11, and horizontal strips 13 uniformly and equidistantly fixed in the inner wall of the outer pipe body 11. U-shaped strips 14 are fixedly installed on the opposite ends of the four horizontal strips 13. Each U-shaped strip 14 has equally spaced circular grooves 15 at its opposite ends. Each pair of U-shaped strips 14 is fixedly fitted with a stress-relieving rib 16. An inner tube 21 is located inside the outer tube 11. Second reinforcing ribs 22 are evenly and evenly fixedly installed inside the inner tube 21. Connecting strips 23 are evenly and evenly fixedly installed on the sidewall of the inner tube 21. Each of the four connecting strips 23 has a strip-shaped groove 24 on its sidewall away from the inner tube 21. Each of the four connecting strips 23 has a through groove 25 that connects to the four strip grooves 24. The horizontal strip 13 and the U-shaped strips 14 slide within the inner tube. In the strip groove 24 and through groove 25, top posts 26 are fixedly installed at equal intervals in the inner walls of the four through grooves 25. Each top post 26 is directly opposite to each circular groove 15. When the outer tube 11 is subjected to pressure, the outer tube 11 undergoes slight deformation during processing. Under the action of this extrusion force, the outer tube 11 will cause the crossbar 13 to move slightly. At this time, the crossbar 13 will cause the U-shaped bar 14 to move slightly. After the crossbar 13 and U-shaped bar 14 slide inside the strip groove 24 and through groove 25, the U-shaped bar 14 will cause the stress relief rib 16 fixed to it to move slightly. The slight deformation of the pressure gradually releases the pressure, while the stress relief rib 16 transmits the pressure to the two U-shaped bars 14 adjacent to the pressure point. However, the U-shaped bars 14 are limited, so the pressure is dispersed. This allows the equipment to quickly disperse the pressure when it is subjected to pressure, thereby enhancing the equipment's pressure resistance. When the U-shaped bars 14 move under force, they will come into contact with the top column 26, and relative sliding will occur between them. Friction will be generated under relative sliding, which will further dilute and disperse the pressure, further enhancing the equipment's pressure resistance.

[0018] To address the problems existing in the prior art, this utility model provides a pressure-resistant concrete drainage pipe. Through the design of the horizontal bar 13, U-shaped bar 14, stress relief rib 16, strip groove 24, and through groove 25, when the equipment is under stress, the horizontal bar 13 and U-shaped bar 14 will slide inside the strip groove 24 and through groove 25. At this time, the U-shaped bar 14 will drive the stress relief rib 16 fixed to it to undergo slight deformation, thereby relieving the pressure. The stress relief rib 16 will transmit the pressure to the two U-shaped bars 14 adjacent to the pressure point. However, the U-shaped bar 14 is limited, so the pressure is dispersed. This allows the equipment to quickly disperse the pressure when it is under pressure during use, thereby enhancing the pressure resistance of the equipment.

[0019] Working principle: In the first step, when the outer tube 11 is subjected to pressure, the outer tube 11 undergoes slight deformation during processing. Under the action of this extrusion force, the outer tube 11 will cause the crossbar 13 to move slightly. At this time, the crossbar 13 will cause the U-shaped bar 14 to move slightly. After the crossbar 13 and the U-shaped bar 14 slide inside the strip groove 24 and the through groove 25, the U-shaped bar 14 will cause the stress relief rib 16 fixed to it to deform slightly, thereby relieving the pressure. The stress relief rib 16 will transmit the pressure to the two U-shaped bars 14 adjacent to the pressure point. However, the U-shaped bar 14 is limited, so the pressure will be dispersed. This allows the equipment to quickly disperse the pressure when it is subjected to pressure during use, thereby enhancing the pressure resistance of the equipment. In the second step, when the U-shaped strip 14 moves under force, it will come into contact with the top column 26, and the two will slide relative to each other. Friction will be generated under relative sliding, which can further dilute and disperse the pressure, thereby further enhancing the pressure resistance of the equipment.

[0020] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
