Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to an irregularly shaped drainage pipe. Background Technology

[0002] In urban construction, industrial production, and daily life, drainage pipes are an indispensable infrastructure, undertaking vital functions such as sewage collection, rainwater drainage, and flood control. They promptly transport domestic sewage and industrial wastewater to treatment facilities, preventing sewage accumulation and environmental pollution; during the rainy season, they quickly drain surface water, avoiding urban flooding and ensuring smooth traffic and resident safety. Whether it's urban underground pipe networks, industrial park sewage systems, or rural wastewater treatment projects, drainage pipes provide core support for maintaining water cycle balance and improving the ecological environment, serving as a crucial guarantee for the normal operation of society.

[0003] However, existing drainage pipes generally suffer from poor pressure resistance. Traditional drainage pipes mostly adopt a single circular or simple rectangular structure, with uniform wall thickness but insufficient overall support strength. Once buried underground, these pipes need to withstand the weight of the backfill soil above, surface vehicle loads, and lateral soil pressure for extended periods. Under these continuous pressures, the pipes are prone to localized stress concentration, especially on the sides and top, which can lead to deformation, dents, or even ruptures due to insufficient structural strength after prolonged use. Utility Model Content

[0004] In view of the technical problem that existing drainage pipes generally have poor pressure resistance, this utility model provides an irregularly shaped drainage pipe.

[0005] The technical solution adopted by this utility model is: an irregularly shaped drainage pipe, including a pipe, the top and bottom of the pipe are arc-shaped structures, the two sides of the pipe have side edges, and the side edges are vertical or arc-shaped arch structures. Multiple sets of reinforcing plates are fixedly connected to the outside of the pipe, and a reinforcing cavity is formed between the reinforcing plates.

[0006] A further feature of this invention is that the reinforcing plate is a square or arched structure, and at least one or more sides of the reinforcing plate are arched for reinforcement, and a control box is fixedly connected to the top of the pipe.

[0007] A further feature of this invention is that the pipe is externally fixedly connected to multiple sets of reinforcing protrusions, which surround and are fixedly connected to the outside of the pipe.

[0008] A further feature of this invention is that the pipe is externally fixedly connected with multiple sets of reinforcing ribs, which are evenly distributed on the outside of the pipe.

[0009] A further feature of this invention is that both the reinforcing ribs and the pipes are provided with through holes.

[0010] A further feature of this invention is that one end of the pipe is fixedly connected to an externally flared connecting pipe, the inner diameter of which is larger than the outer diameter of the pipe.

[0011] A further feature of this invention is that the externally fixed connection of the flared connecting pipe includes multiple sets of reinforcing rings.

[0012] A further feature of this invention is that the flared connecting pipe is connected to the pipeline and is integrally formed.

[0013] The beneficial effects of this utility model are as follows: This utility model solves the problem of poor pressure resistance of traditional drainage pipes. The top and bottom of the pipe adopt an arc-shaped structure, and the two sides are provided with vertical or arc-shaped arched sides. The arc-shaped mechanical properties are used to disperse external pressure, reduce local stress concentration, and greatly improve the overall pressure resistance. It can withstand the weight of backfill soil, ground load and soil lateral pressure for a long time, avoiding deformation, dent or cracking. Multiple sets of external reinforcing plates form a reinforcing cavity and construct a multi-layer support structure, further enhancing the stability of the pipe structure and its tensile and compressive resistance.

[0025] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described below.

[0026] To address the problems existing in the background technology, this application proposes the following technical solution: an irregularly shaped drainage pipe, including a pipe 1, the top and bottom of the pipe 1 being arc-shaped structures, the two sides of the pipe 1 having side edges 4, and the side edges 4 being vertical or arc-shaped arched structures, multiple sets of reinforcing plates 7 being fixedly connected to the outside of the pipe 1, forming a reinforcing cavity 8 between the reinforcing plates 7, the reinforcing plates 7 being square or arched structures, multiple sets of reinforcing protrusions 2 being fixedly connected to the outside of the pipe 1, the reinforcing protrusions 2 being fixedly connected around and surrounding the outside of the pipe 1, multiple sets of reinforcing ribs 6 being fixedly connected to the outside of the pipe 1, the reinforcing ribs 6 being evenly distributed on the outside of the pipe 1, and through holes 5 being provided in both the reinforcing ribs 6 and the pipe 1, one end of the pipe 1 being fixedly connected to an outwardly flared connecting pipe 9, the inner diameter of the outwardly flared connecting pipe 9 being larger than the outer diameter of the pipe 1, multiple sets of reinforcing rings 10 being fixedly connected to the outside of the outwardly flared connecting pipe 9, the outwardly flared connecting pipe 9 being connected to the pipe 1 and being integrally formed; the pipe 1, as the core conveying component of the drainage system, its structural design directly affects the drainage efficiency and service life. The use of an arc-shaped structure at the top and bottom is an optimized design based on mechanical principles: the arc shape at the top can disperse the vertical forces such as soil pressure and ground load from above to both sides, avoiding pressure concentration at the top center point of pipe 1 and reducing the risk of deformation or rupture of the pipe wall due to excessive local stress; the arc shape at the bottom can guide the water flow smoothly along the arc surface, reduce water flow resistance, reduce the accumulation of impurities in sewage at the bottom of pipe 1, and at the same time, the arc structure itself has stronger anti-compression capacity and can withstand the reaction force from the soil below, ensuring that pipe 1 maintains a stable laying posture in the buried environment.

[0027] In this embodiment, the side edges 4 on both sides of the pipeline 1 are designed as vertical or arched structures, further enhancing the overall pressure-bearing performance. When facing lateral soil pressure, the vertical side edges 4 can uniformly transmit force through the planar structure, making them suitable for use in areas with high soil density. The arched side edges 4 draw on the mechanical advantages of arched architecture, converting lateral pressure into axial force along the arch surface and dispersing stress using the tensile strength of the material itself. Especially in soft soil or environments with lateral displacement, they can better resist soil compression and prevent lateral deformation of the pipeline 1.

[0028] In this embodiment, multiple sets of reinforcing plates 7 are fixed externally to the pipe 1 and spaced apart along the length of the pipe 1, forming a closed reinforcing cavity 8 between adjacent reinforcing plates 7. The reinforcing plates 7 themselves act as rigid support structures, directly enhancing the deformation resistance of the outer wall of the pipe 1. The reinforcing cavities 8 further disperse external pressure through the buffering effect of air or filling materials. Simultaneously, the cavity structure reduces the overall weight of the pipe 1, lowering the difficulty of transportation and installation. This composite structure of "rigid support + cavity buffering" allows the pipe 1 to resist external forces through the reinforcing plates 7 and absorb some impact energy through the cavity when subjected to pressure, significantly improving the impact resistance and deformation resistance of the pipe 1.

[0029] In this embodiment, the reinforcing plate 7 is a square or arched structure, and at least one or more sides of the reinforcing plate 7 are arched. The top of the pipe 1 is fixedly connected to a control box 11, which is used to store control devices. Multiple sets of reinforcing ridges 2 are fixedly connected to the outside of the pipe 1. The reinforcing ridges 2 surround and are fixedly connected to the outside of the pipe 1. Multiple sets of reinforcing ribs 6 are fixedly connected to the outside of the pipe 1. The reinforcing ribs 6 are evenly distributed on the outside of the pipe 1. Through holes 5 are provided in both the reinforcing ribs 6 and the pipe 1.

[0030] In this embodiment, the reinforcing plate 7 adopts either a square or arched structure, each with its own advantages: the square reinforcing plate 7 has a stable structure and a large contact area with the outer wall of the pipe 1, which can evenly transfer external forces to the main body of the pipe 1, making it suitable for scenarios requiring strong rigid support; the arched reinforcing plate 7 utilizes the natural pressure-bearing characteristics of the arched structure to transfer external pressure to both ends, with small deformation, making it less prone to damage under long-term pressure, thus extending the service life of the reinforcing structure. The two structures can be flexibly selected according to actual engineering needs to ensure that the reinforcement effect is adaptable to different geological environments.

[0031] Multiple sets of reinforcing ridges 2 are arranged around the outside of pipe 1 to form a ring-shaped constraint structure. This design can effectively resist the radial deformation of pipe 1. When pipe 1 is subjected to soil pressure from all sides, the reinforcing ridges 2 distribute the local pressure to the entire outer perimeter of pipe 1 through ring tension, preventing pipe 1 from bulging or denting due to excessive local stress. At the same time, the reinforcing ridges 2 are tightly connected to the outer wall of pipe 1, enhancing the overall structural integrity of pipe 1 and preventing segmental deformation of pipe 1 during installation or use.

[0032] In this embodiment, the reinforcing ribs 6, evenly distributed on the outside of the pipe 1, further refine the stress dispersion path. Each set of reinforcing ribs 6 extends along the axial direction of the pipe 1, forming a three-dimensional grid-like support system with the reinforcing ridges 2 and the reinforcing plates 7. This grid structure ensures that the stress points on the outer wall of the pipe 1 are evenly distributed. Even if local pressure anomalies occur under complex geological conditions, the stress can be quickly transferred to the entire support system through the reinforcing ribs 6, avoiding single-point failure. The reinforcing ribs 6 and the through holes 5 provided in the pipe 1 have multiple practical values: the through holes 5 can reduce the overall weight of the pipe 1, reducing material consumption and transportation load; during installation, the through holes 5 can be used to install fixing anchors, facilitating the connection between the pipe 1 and the surrounding soil or fixed structures; at the same time, the through holes 5 reserve space for future intelligent transformation of the pipeline network, allowing the installation of monitoring cables, sensors, and other equipment to achieve real-time monitoring of the operating status of the pipe 1.

[0033] In this embodiment, one end of the pipe 1 is fixedly connected to an outwardly flared connecting pipe 9. The inner diameter of the outwardly flared connecting pipe 9 is larger than the outer diameter of the pipe 1. Multiple sets of reinforcing rings 10 are fixedly connected to the outside of the outwardly flared connecting pipe 9. The outwardly flared connecting pipe 9 is connected to the pipe 1 and is integrally formed. In this embodiment, the outwardly flared connecting pipe 9 at the end of the pipe 1 is a key structure to ensure the reliability of the connection of the pipe 1. Its design, with an inner diameter larger than the outer diameter of the pipe 1, provides greater installation tolerance when docking with other pipes 1. Even with slight dimensional deviations or installation angle errors, a tight docking can be achieved through the inclusiveness of the outward flare, reducing the risk of leakage due to improper connection. The outward flare structure also reduces the resistance of water flow at the connection point, preventing sewage from forming eddies or accumulating at the interface, ensuring smooth drainage.

[0034] In this embodiment, multiple sets of reinforcing rings 10 are distributed along the length of the connecting pipe 9 outside the flared connecting pipe, which specifically enhances the structural strength of the connection part. The connection part is the weak link of the pipeline 1 system and is easily damaged due to stress concentration or installation stress. The reinforcing rings 10 disperse the external force at the interface to the main body of the pipeline 1 through the ring constraint, preventing the connecting pipe from cracking due to the pressure of the connection or the lateral force of the soil.

[0035] In this embodiment, the flared connecting pipe 9 and the pipe 1 are manufactured using an integral molding process, fundamentally eliminating the seams at the connection point and avoiding the leakage risks that may occur with traditional welding or flange connections. The integral molding structure allows the pipe 1 and the connecting pipe to form a continuous stress-bearing unit, resulting in smoother pressure transmission and the absence of stress concentration points at the joints, significantly improving the fatigue resistance and sealing performance of the connection. This design not only simplifies the installation process and reduces the use of connecting accessories, but also maintains the structural stability of the interface over a long period, reducing subsequent maintenance costs and ensuring that the drainage system maintains good sealing and safety during long-term operation.

[0036] In this embodiment, the pipe 1 is optimized in multiple dimensions to organically combine pressure-bearing capacity, connection reliability, and functional expandability. The arc-shaped top 3, bottom, and side 4 structures disperse internal and external pressures, while the reinforcing plate 7, reinforcing convex strip 2, and reinforcing rib 6 form a three-dimensional support system. The outwardly flared connecting pipe 9 ensures convenient connection and sealing, and the through hole 5 is designed to reserve space for intelligent upgrades. This comprehensively solves the problems of easy deformation, difficult connection, and high maintenance costs of traditional drainage pipes 1 in buried environments, providing a more durable and efficient pipe 1 solution for urban drainage, industrial sewage discharge, and other scenarios.
