Description

Technical Field

[0001] This utility model relates to the field of municipal engineering sewage treatment technology, and more specifically, to a through-type sewage pipeline. Background Technology

[0002] In municipal construction and agricultural production, sewage pipe networks frequently cross roads or farmland. These networks operate in complex environments and must withstand interference from various external factors, such as vehicle traffic, soil compression, and agricultural machinery operations. Moreover, existing sewage pipes are typically made of plastic or metal. While these materials possess a certain degree of strength, they are prone to deformation or breakage during long-term use, especially under high pressure or high flow conditions, thus exhibiting a general problem of insufficient strength.

[0003] To improve the structural strength of pipelines, existing technologies include increasing pipe wall thickness or using high-strength materials. However, while increasing strength, these methods also significantly increase weight and cost. Other methods involve installing support components on the inner wall of the pipe to enhance strength, as seen in Chinese patent applications CN215891589U and CN216643331U. These applications utilize support components on the inner wall to improve structural strength, but these components are generally complex, which can severely reduce the actual water flow performance inside the pipe, making it susceptible to impact and affecting its structural strength. Furthermore, installation is inconvenient. Utility Model Content

[0004] 1. Technical problems to be solved To address the technical problems of complex internal support structures and inconvenient installation in existing pipeline technologies, this utility model provides a novel through-type sewage pipeline. This solution optimizes the design of the internal support components of the pipeline body. These components have a simpler structure, which not only improves the structural strength of the sewage pipeline but also effectively reduces adverse effects on its internal water flow performance and simplifies the installation process.

[0005] 2. Technical solutions adopted To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses a through-type sewage pipe, which includes a pipe body and multiple sets of supporting components. The multiple sets of supporting components are distributed at intervals along the axial direction of the pipe body on its inner wall and are integrally formed with the pipe body. Each set of supporting components is centrally located on the inner wall of the pipe body and includes two cross-distributed supporting bars with an included angle of 60° to 75°.

[0006] Furthermore, the support bar is a hollow cylindrical structure.

[0007] Furthermore, the outer wall of the pipe body is provided with a plurality of annular reinforcing ribs spaced apart, and the annular reinforcing ribs coincide with the corresponding supporting components along the axial direction of the pipe body.

[0008] Furthermore, the distance between the end of the pipe body and its adjacent support component is approximately 1 / 3 to 1 / 2 of the pipe diameter; the spacing between two adjacent sets of support components is 2 to 3 times the pipe diameter.

[0009] Furthermore, the pipe is equipped with a detachable interception net at its end, which has a conical structure.

[0010] Furthermore, adjacent pipes are connected by quick-connect couplings, and the intercepting net can be detachably installed on the inner wall of the quick-connect coupling.

[0011] Furthermore, the outer ring of the bottom surface of the interception net is provided with spaced connecting joints along its circumference for detachable connection between the interception net and the quick connector.

[0012] Furthermore, both ends of the pipe are equipped with intercepting nets, with the apexes of the two nets facing inwards towards the pipe body.

[0013] Furthermore, the apex angle of the interception net is 45°~60°.

[0014] Furthermore, the outer wall of the pipe body is provided with multiple grooves along its circumference, and each groove extends along the axis of the pipe body to both ends, and each groove is provided with a detection metal strip nested therein.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages: (1) This utility model optimizes the relative connection relationship between the supporting components and the pipe body. Specifically, multiple sets of supporting components are distributed at intervals along the axis of the pipe body on its inner wall, and are integrally formed with the pipe body. This arrangement is simple in structure, which can not only effectively improve the supporting strength of the pipe body, but also greatly reduce the adverse effects on the internal water flow performance of the pipe body, and no subsequent installation steps are required. Furthermore, based on the comprehensive consideration of the structural strength and water flow resistance of the pipe body, the included angle between the two supporting bars in the supporting components is selected to be 60~75°.

[0016] (2) This utility model further optimizes the relative positional relationship between the supporting component and the annular reinforcing rib on the outer wall of the pipe body. Specifically, the annular reinforcing rib and the corresponding supporting component coincide along the axial direction of the pipe body. Through the relative positional design of the supporting component and the annular reinforcing rib, the pipe can better enhance its resistance to deformation, thereby greatly extending the service life of the sewage pipe, reducing the frequency of pipe network replacement, and thus reducing the total life cycle cost.

[0017] (3) This utility model further optimizes the installation and connection of the interception net. Specifically, the end of the pipe is provided with a detachable interception net of a conical structure, thereby ensuring the filtration effect while reducing the adverse impact on the water flow performance of the pipe body. Furthermore, the interception net is detachably installed on the inner wall of the quick connector, facilitating the quick replacement of individual interception nets. Even further, both ends of the pipe are provided with interception nets, with the apexes of the two interception nets facing the inside of the pipe body, thereby further blocking impurities carried by the backflow of sewage inside the pipe.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0023] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0024] It should be noted that there are two angles between the two support bars 201, which are parallel angles. In the following embodiments, the angles referred to are the smaller angle θ1.

[0025] This embodiment provides a through-type sewage pipe, referenced... Figure 1 , Figure 3 As shown, the pipeline includes a pipeline body 1 and multiple sets of support components 2. The multiple sets of support components 2 are distributed at intervals along the axial direction of the pipeline body 1 on its inner wall and are integrally formed with the pipeline body 1. Each set of support components 2 is centrally located on the inner wall of the pipeline body 1 and includes two cross-distributed support bars 201. The included angle θ1 of the two support bars 201 is 60°~75°.

[0026] in, Figure 1 The straight dashed lines indicated in the figure represent the support component 2. The elliptical dashed lines are only used to indicate the relative position of the support component 2 and the pipe body 1. The inner wall area of ​​the pipe body 1 corresponding to the support component 2 may not be provided with annular reinforcing ribs protruding towards its center.

[0027] Generally, while installing support components 2 inside the pipe body 1 can improve the strength of the pipe body 1, it also reduces the actual cross-sectional area for water flow inside the pipe. To minimize the water flow resistance inside the pipe body 1, multiple sets of support components 2 are arranged at the same angle relative to the pipe body 1, i.e., their postures are consistent relative to the pipe body 1. Furthermore, by designing the support components 2 and the pipe body 1 as an integrally formed structure, this arrangement greatly reduces the adverse effects on the water flow performance inside the pipe body 1 compared to support components placed later in the pipe body 1, and eliminates the need for subsequent installation steps. Because there are multiple possible laying angles for the pipe body 1, each set of support components 2 is centrally located on the inner wall of the pipe body 1. The support bar 201 divides the inner wall surface of the pipe body 1 into four smaller fan-shaped areas, reducing the free span of the pipe wall, thereby improving the overall circumferential stiffness and buckling stability of the pipe. The included angle between the two support bars 201 in each set of support components 2 is between 60° and 75°. This is because: if the two support bars 201 are arranged at right angles, i.e., the included angle θ1 is 90°, the support bars 201 divide the inner ring wall of the pipe body 1 into four identical regions. This provides the best effect on improving the pipe strength, but the water flow will directly impact the support bars 201, generating strong turbulence and vortices, resulting in significant local head loss. Moreover, the right-angled edges between the two support bars 201 are prone to catching debris such as fibers, hair, and plastic, forming blockages, thereby reducing the flow area inside the pipe body 1 and increasing water flow resistance. Conversely, if the included angle between the two support bars 201 is too small, for example, θ1 is 45°, although the obstruction to water flow is small, i.e., the water flow rate is large, it will reduce the support for the pipe body 1 to some extent. Therefore, the included angle θ1 of the two support bars 201 is selected to be 60~75°. Preferably, the included angle θ1 of the support bars 201 is 60°, 65°, 70°, or 75°, so as to achieve a balance between strength and flow rate.

[0028] Specifically, the support bar 201 is a hollow cylindrical structure. This structural design not only ensures the supporting strength of the pipe body 1, but also helps to reduce the overall weight of the pipe, thereby reducing the difficulty of transportation and construction.

[0029] Generally, the outer wall of the pipe body 1 is provided with multiple annular reinforcing ribs spaced apart, and these annular reinforcing ribs coincide with the corresponding support components 2 along the axial direction of the pipe body 1. That is, the inner wall of the area of ​​the pipe body 1 corresponding to a single annular reinforcing rib is provided with a support component 2. By designing the relative positions of the support components 2 and the annular reinforcing ribs, this pipe better enhances the pipe's resistance to deformation, greatly extending the service life of the sewage pipe, thereby reducing the frequency of pipe network replacement and thus reducing the total life cycle cost.

[0030] It should be noted that the annular reinforcing rib and the corresponding supporting component 2 can also be arranged alternately along the axial direction of the pipe body 1.

[0031] More specifically, the distance between the end of the pipe body 1 and its adjacent support component 2 is about 1 / 3 to 1 / 2 of the pipe diameter; the spacing between two adjacent sets of support components 2 is 2 to 3 times the pipe diameter, so as to effectively support the pipe body 1 while avoiding excessive increase in the self-weight of the pipe.

[0032] Generally, existing sewage pipes are made of polyethylene or polypropylene as the base material, supplemented by various reinforcing phases. The pipe body 1 is typically injection molded. Correspondingly, the support component 2 is integrally molded with the pipe body 1 using an injection molding process.

[0033] Further preferred options, refer to Figure 2 As shown, the end of the pipe is equipped with a detachable interception net 4. The interception net 4 has a conical structure, which reduces the adverse effects on the water flow performance of the pipe body 1 while ensuring the filtration effect. The aperture of the interception net 4 can be adjusted according to the actual situation of impurities in the local sewage.

[0034] As an extension solution, two adjacent pipes are connected by a quick connector. The interceptor net 4 can be detachably installed on the inner wall of the quick connector, which facilitates the quick replacement of the individual interceptor net 4 and the convenient cleaning of suspended objects inside the interceptor net 4. It is suitable for scenarios that require frequent cleaning.

[0035] The quick-connector can be detachably installed at the ends of two adjacent pipes via a snap-fit ​​connection or a threaded connection. This quick-connector is existing technology and will not be described in detail here.

[0036] As a further extension, the outer ring of the bottom surface of the interceptor net 4 is provided with spaced connecting joints 401 along its circumference for detachable connection between the interceptor net 4 and the quick connector. Preferably, the interceptor net 4 and the quick connector are connected by bolts, and correspondingly, the connecting joint 401 is provided with connecting holes for installing connecting screws.

[0037] In some implementations, both ends of the pipe are equipped with interception nets 4, with the apexes of the two interception nets 4 facing the inside of the pipe body 1, thereby further blocking impurities carried by the backflow of sewage inside the pipe.

[0038] In other embodiments, the apex angle θ2 of the interceptor mesh 4 is 45°~60°. This apex angle design is based on a comprehensive consideration of performance factors such as self-cleaning and flow regime effects, specifically as follows: When the apex angle θ2 is greater than 60°, the intercepted impurities are more likely to "hang" on the filter surface rather than slide to the bottom, easily causing blockage. This means a covering layer is easily formed on the water-facing side of the interceptor mesh 4, which rapidly increases flow resistance, leading to a sharp increase in pressure loss and greater cleaning difficulty. If the apex angle is between 30° and 45°, it has a significant impact on the flow regime. The steep conical surface will generate significant disturbance to the fluid, easily producing eddies and turbulence, resulting in a large local pressure loss and a small effective filtration area. Simultaneously, at higher flow velocities, impurities accumulated at the bottom may be re-rolled up by turbulence. Preferably, the apex angle θ2 of the interceptor mesh 4 is 45°, 50°, 55°, or 60°.

[0039] As a further preferred embodiment of any of the above embodiments, the outer wall of the pipe body 1 is provided with a plurality of grooves along its circumferential direction, and a single groove extends along the axis of the pipe body 1 to both ends therein, and each groove is provided with a detection metal strip 3 nested therein.

[0040] In one specific embodiment, the sewage pipe of this embodiment is used to cross urban branch roads. The pipe is as follows: the inner diameter of the pipe body 1 is 200mm and the wall thickness is 15mm. It is made of polyethylene composite material as the matrix and bamboo fiber as the reinforcing phase. The outer wall has annular reinforcing ribs with a height of 5mm, a width of 8mm, and a spacing of 300mm. The positioning bosses at both ends have a height of 3mm.

[0041] The quick-connect coupling is threaded to the pipe body 1. Correspondingly, the inner wall of the quick-connect coupling has an M200 thread connection and a sealing ring made of nitrile rubber with a diameter of 200mm and a thickness of 3mm. The interceptor mesh 4 is a stainless steel filter with a 5mm aperture and a 45° apex angle θ2.

[0042] The support component 2 includes two cross-distributed support bars 201, which intersect at the middle. It is a hollow cylindrical structure with an outer diameter of 8 mm and a wall thickness of 2.5 mm. The distance between two adjacent support components 2 is 500 mm.

[0043] Two detection metal strips 3 are used, each 10mm wide and 2mm thick. These two strips are evenly distributed along the circumference of the outer wall of the pipe body 1 within its grooves, meaning they are 180° apart circumferentially. The grooves in the pipe body 1 are fitted to the dimensions of the detection metal strips 3, ensuring they are fixed within the grooves. Specifically, the outer side of the detection metal strip 3 is flush with or completely within the groove, and the thickness of the detection metal strip 3 is less than the thickness of the groove, thus not affecting the installation and external protection of the sewage pipe. Furthermore, the dimension of the detection metal strip 3 along the axial direction of the pipe body 1 is greater than the dimension of the pipe body 1 (also called the length direction), with both ends of each strip extending 10mm beyond the end of the pipe body 1. This facilitates the formation of continuously aligned detection metal strips 3 when splicing multiple pipe sections, thus creating a complete "detection signal band," achieving a ground-penetrating radar positioning accuracy of over 95%.

[0044] In another specific embodiment, the sewage pipe of this embodiment is used to traverse a farmland scenario. The specific dimensions of the pipe are as follows: the inner diameter of the pipe body 1 is 500mm, the wall thickness is 30mm, and it uses polypropylene composite material as the matrix and straw fiber as the reinforcing phase; the height of its outer wall ring reinforcing ribs is 10mm, the width is 15mm, the spacing is 500mm, and the height of the positioning bosses at both ends is 5mm.

[0045] The quick-connect coupling is snap-fitted to the pipe body 1, and its inner wall is equipped with a sealing ring made of nitrile rubber with a diameter of 500mm and a thickness of 5mm. The intercepting mesh 4 is a high-strength nylon filter with a pore size of 15mm and a 60° apex angle.

[0046] The support component 2 includes two cross-distributed support bars 201, which intersect at the middle. It is a hollow cylindrical structure with an outer diameter of 15 mm and a wall thickness of 2.5 mm. The distance between two adjacent support components 2 is 800 mm.

[0047] The system comprises four detection metal strips 3, each 20mm wide and 5mm thick. These four strips are evenly distributed along the circumference of the outer wall of the pipe body 1 within its grooves, with adjacent strips spaced 90° apart circumferentially. The grooves in the pipe body 1 are fitted to the dimensions of the detection metal strips 3, ensuring they are fixed within the grooves. Specifically, the outer walls of the detection metal strips 3 are flush with or completely within the grooves, thus not affecting the installation and external protection of the sewage pipe. Furthermore, the dimensions of the detection metal strips 3 along the axial direction of the pipe body 1 are greater than the dimensions of the pipe body 1 (also known as the length direction). Both ends of each detection metal strip 3 extend 10mm beyond the end of the pipe body 1. The ends of each detection metal strip 3 extend 15mm beyond the end of the pipe body 1. This facilitates the formation of continuously aligned detection metal strips 3 when splicing multiple pipe sections, thus creating a complete "detection signal band." The ground-penetrating radar positioning accuracy can reach over 95%.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
