Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, and in particular relates to a reinforced concrete drainage pipe with a base and a flexible interface with a pre-embedded rubber ring. Background Technology

[0002] A drainage pipe is a type of pipe used for drainage. In traditional forms, it is a rigid reinforced concrete pipe. Its load-bearing capacity depends on the strength of the pipe body and the quality of the underlying bedding layer. It requires the laying of sand or concrete bedding layers to form a support system and relies on independent rubber rings for water sealing.

[0003] Currently, when using excavated plain fill for drainage pipe bedding, the compaction and wrapping angle are greatly affected by human factors, easily leading to uneven stress on the pipe body. On-site poured concrete bedding is costly and complicated, and insufficient wrapping angle or an uncompacted bedding can cause point loads on the pipe wall, leading to pipe cracking and leakage. Traditional rubber rings are prone to displacement during on-site installation, resulting in leakage that pollutes the soil, damages the bedding, and even causes road collapse. The root cause is that the bedding and the pipe body are separate, and the load transfer depends on the compaction of the soil. Furthermore, the rubber rings are not pre-embedded for restraint and are prone to dislocation. Utility Model Content

[0004] This utility model provides a reinforced concrete drainage pipe with a base and a flexible interface with a pre-embedded rubber ring, which aims to solve the problem of unstable subgrade at the connection of drainage pipes.

[0005] This utility model is implemented as follows: a reinforced concrete drainage pipe with a base and a flexible interface with a pre-embedded rubber ring includes: a pipe body; an integrally formed base at the bottom of the pipe body; a flexible socket end at one end of the pipe body and a plug-in end adapted to the flexible socket end at the other end; and a pre-embedded rubber ring on the inner side of the flexible socket end.

[0006] Preferably, the base and the tube are formed by simultaneous casting, and the width of the base is smaller than the diameter of the tube.

[0007] Preferably, the rubber ring is wedge-shaped, and the wedge-shaped structure is adapted to the contact surface of the plug end.

[0008] Preferably, the rubber ring is fixed to the inner side of the flexible socket end by inlay.

[0009] Preferably, the rubber ring is made of aging-resistant rubber material.

[0010] Preferably, the tube body is provided with a steel reinforcement skeleton to increase strength.

[0011] Compared with related technologies, the reinforced concrete drainage pipe with base and pre-embedded rubber ring flexible interface provided by this utility model has the following beneficial effects: By integrating the pipe body and base into one piece, the traditional padding layer is replaced, reducing the impact of construction fluctuations. The steel reinforcement skeleton inside the pipe body enhances the structural strength and improves the overall load-bearing stability. At the same time, the pre-embedded rubber ring on the inner side of the flexible socket end adopts a wedge-shaped structure, is inlaid and fixed, and is made of aging-resistant rubber material, forming a stable sealing surface with the plug end, reducing the risk of leakage. Overall, the installation of drainage pipes is convenient. Attached Figure Description

[0014] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0015] This utility model embodiment provides a reinforced concrete drainage pipe with a base and a flexible interface with a pre-embedded rubber ring, such as Figure 1-3 As shown, the reinforced concrete drainage pipe with base and pre-embedded rubber ring flexible interface includes: pipe body 1; the bottom of the pipe body 1 is provided with an integrally formed base 2; one end of the pipe body 1 is provided with a flexible socket end 3, and the other end is provided with a plug end 4 adapted to the flexible socket end 3; the flexible socket end 3 is provided with a pre-embedded rubber ring 5 on the inner side.

[0016] In this embodiment, after the reinforced concrete drainage pipe with base and pre-embedded rubber ring flexible interface is transported to the construction site, there is no need to lay an additional pad layer. The base 2 at the bottom of the pipe body 1 is placed directly on the foundation for initial positioning. Then, the plug end 4 of another pipe is aligned with the flexible socket end 3 of the installed pipe and slowly pushed in to connect the two. At this time, the pre-embedded rubber ring 5 on the inner side of the flexible socket end 3 is in close contact with the plug end 4, and the pipe connection is completed. The base 2 is integrally formed with the pipe body 1, replacing the traditional padding layer to provide continuous and uniform support for the pipe body 1. This reduces the problem of uneven stress on the pipe body 1 caused by fluctuations in the construction quality of the padding layer, and lowers the risk of cracking and damage to the pipe body 1. At the same time, it eliminates the traditional padding layer laying process, which helps to improve construction efficiency. The rubber ring 5 is pre-fixed to the inside of the flexible socket end 3 to avoid displacement and twisting during on-site installation. This ensures that the rubber ring 5 and the plug end 4 form a stable sealing surface after docking, enhances the anti-seepage performance of the interface, and reduces problems such as soil pollution, padding layer damage and road collapse caused by leakage.

[0017] In a further preferred embodiment of the present invention, the base 2 and the tube 1 are formed by synchronous casting, and the width of the base 2 is smaller than the diameter of the tube 1.

[0018] In this embodiment, the base 2 and the pipe body 1 are cast and formed simultaneously to form a continuous integral structure, so that the load on the pipe body 1 can be transferred to the foundation more evenly through the base 2, reducing the uneven stress on the pipe body 1 caused by the subbase problem and improving the overall load-bearing stability of the pipeline. The width of the base 2 is smaller than the diameter of the pipe body 1. This ensures the stability of the pipe body 1 while reducing the amount of material used, which helps control costs. Compared with traditional subbase construction, it eliminates the need for on-site laying and compaction, thus speeding up the construction process.

[0019] In a further preferred embodiment of the present invention, the rubber ring 5 is wedge-shaped, and the wedge-shaped structure is adapted to the contact surface of the plug end 4.

[0020] In this embodiment, when connecting pipes, the insertion end 4 of one pipe is aligned with the wedge-shaped rubber ring 5 on the inner side of the flexible socket end 3 of the other pipe, and slowly pushed in so that the insertion end 4 contacts and is squeezed with the wedge-shaped rubber ring 5. By utilizing the compatibility between the wedge structure and the contact surface of the insertion end 4, the two are tightly fitted together to complete the sealed connection. The wedge-shaped rubber ring 5 is adapted to the contact surface of the plug end 4, and can gradually increase the contact pressure during the docking process, making the sealing surface fit more tightly and helping to improve the anti-leakage capability of the interface. Compared to traditional rubber rings, the wedge-shaped structure increases the contact area with the insertion end 4. With a suitable contact surface design, it reduces the risk of leakage caused by insufficient fit between the rubber ring and the interface, and enhances the sealing stability of the pipe interface.

[0021] In a further preferred embodiment of this utility model, the rubber ring 5 is fixed to the inner side of the flexible socket end 3 by an inlay method.

[0022] In this embodiment, before the pipe leaves the factory, the rubber ring 5 is fixed to the inside of the flexible socket end 3 by embedding. During on-site installation, the plug end 4 of another pipe is directly aligned with the flexible socket end 3 and pushed in, so that the rubber ring 5 and the plug end 4 naturally contact and form a seal, without the need for additional adjustment of the position of the rubber ring 5. The embedded fixing method provides a stable installation base for the rubber ring 5, reducing the possibility of displacement or detachment of the rubber ring 5 due to external force or pipe connection impact during on-site construction, which helps maintain the integrity of the sealing structure; it eliminates the steps of traditional rubber ring on-site installation and manual adjustment, making the pipe connection process simpler, reducing the impact of manual operation on the sealing effect, and shortening the installation time and improving construction efficiency.

[0023] In a further preferred embodiment of this utility model, the rubber ring 5 is made of aging-resistant rubber material.

[0024] In this embodiment, the rubber ring 5 is made of aging-resistant rubber material and is pre-embedded inside the flexible socket end 3. When the pipe is connected, the plug end 4 contacts and squeezes the rubber ring 5. The material maintains its elasticity during long-term use and continuously forms a sealing state with the plug end 4. The characteristics of the aging-resistant rubber material enable the rubber ring 5 to maintain good elasticity and structural stability under the influence of external environment (such as temperature changes and soil erosion), thus extending the effective period of the sealing function.

[0025] In a further preferred embodiment of the present invention, the tube body 1 is provided with a steel reinforcement skeleton to increase strength.

[0026] In this embodiment, a steel reinforcement cage is pre-installed inside the pipe body 1 and is cast and formed synchronously with the pipe body 1. After the pipe is installed, the steel reinforcement cage plays a supporting role inside the pipe body 1 and works with the base 2 to bear the external load and internal water flow pressure. The steel reinforcement cage enhances the overall structural strength of the pipe body 1, making it less prone to cracking or deformation when subjected to foundation reaction force, soil pressure or internal water pressure, thus improving the load-bearing capacity of the pipe body 1.

[0027] In summary, compared with related technologies, the pipe body 1 and the base 2 are integrally formed, replacing the traditional padding layer and reducing the impact of construction fluctuations. The steel reinforcement skeleton inside the pipe body 1 enhances the structural strength and improves the overall load-bearing stability. At the same time, the pre-embedded rubber ring 5 on the inner side of the flexible socket end 3 adopts a wedge-shaped structure, is inlaid and fixed, and is made of aging-resistant rubber, forming a stable sealing surface with the plug end 4, reducing the risk of leakage. Overall, the installation of drainage pipes is convenient.
