Description

Technical Field

[0001] This utility model relates to the field of permeable pipe technology, and in particular to a permeable pipe that prevents clogging. Background Technology

[0002] Permeable pipes are a new type of pipe material with reverse filtration and water permeability. They are used in many environments, such as in places with high groundwater levels or poor drainage, where permeable pipes can effectively lower the groundwater level and prevent soil flooding.

[0003] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: In existing permeable pipes, there are several permeable holes on the pipe wall that connect the inside and outside of the permeable pipe. When buried underground, the permeable holes will directly contact the soil. At this time, the soil will be squeezed and stuck in the permeable holes due to radial pressure, which will cause blockage and affect the permeability. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing permeable pipes have the disadvantage that the permeable holes are easily blocked by mud. Therefore, we propose a permeable pipe that is resistant to blockage.

[0005] To achieve the above objectives, this application adopts the following technical solution: a clog-resistant permeable pipe, comprising a permeable pipe body: both ends of the permeable pipe body are equipped with mounting rings, a fine filter layer is sleeved on the outer surface of the permeable pipe body, both ends of the fine filter layer are fixed to the mounting rings, and a coarse filter layer is sleeved on the outer surface of the mounting rings, both ends of the coarse filter layer are fixed to the mounting rings.

[0006] Preferably, the fine filter layer is made of polypropylene filter mesh.

[0007] Preferably, the coarse filter layer is made of non-woven geotextile.

[0008] Preferably, a guide ring is fixed on the side of the mounting ring near the permeable pipe body, the guide ring is located at both ends inside the permeable pipe body, and the guide ring has a conical structure.

[0009] Preferably, the mounting ring has a plurality of reinforcing ribs fixed on its opposing surfaces, and the reinforcing ribs are distributed circumferentially around the axis of the mounting ring.

[0010] Preferably, the coarse filter layer is fitted with a plurality of uniformly distributed reinforcing rings, which are fixed to the reinforcing ribs.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, a double-layer filtration structure is formed by combining a polypropylene filter screen with a non-woven geotextile. This fully leverages the synergistic advantages of the two materials, significantly improving the overall protective performance of the permeable pipe. This well-defined hierarchical filtration design avoids rapid clogging caused by an excessively fine single material and solves the problem of insufficient interception of fine particles by a single coarse filter material. In addition, the double-layer structure can buffer soil stress, adapt to foundation deformation, and extend the life of the permeable pipe.

[0013] In this invention, a composite reinforcement scheme with the synergistic effect of reinforcing ribs and reinforcing rings is used to form a longitudinal and radial skeleton support system. This three-dimensional reinforcement structure works in three dimensions: the axial reinforcing ribs effectively resist the bending stress caused by uneven soil settlement and prevent longitudinal deformation of the pipeline; the radial reinforcing rings constrain the ellipticity of the pipeline and resist the radial compression caused by external soil pressure; and the intersection of the two forms a spatial grid structure, which improves the compressive strength of the pipe body.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figures 1-3As shown, this utility model provides a technical solution: a clog-resistant permeable pipe, including a permeable pipe body 1. Both ends of the permeable pipe body 1 are fitted with mounting rings 2. A fine filter layer 3 is sleeved on the outer surface of the permeable pipe body 1, with both ends of the fine filter layer 3 fixed to the mounting rings 2. A coarse filter layer 4 is sleeved on the outer surface of the mounting rings 2, with both ends of the coarse filter layer 4 fixed to the mounting rings 2. The fine filter layer 3 and the coarse filter layer 4 are combined to form a double-layer filtration structure, significantly improving the overall protective performance of the permeable pipe. Through the clear hierarchical filtration design of coarse and fine filters, it avoids rapid clogging caused by excessively fine single materials and solves the problem of insufficient interception of fine particles by a single coarse filter material. In addition, the double-layer structure can buffer soil stress, adapt to foundation deformation, and extend the service life of the permeable pipe.

[0022] Reference Figure 3 As shown in this embodiment: the fine filter layer 3 is made of polypropylene filter mesh. Polypropylene filter mesh has significant advantages as the outer filter material of the permeable pipe: it has excellent chemical stability, is resistant to acids and alkalis, corrosion and is not subject to microbial erosion, and is not prone to aging after long-term buried use; at the same time, it has high mechanical strength and deformation resistance, can withstand soil pressure and construction stress, and maintain a stable permeable structure. Its controllable pore size and smooth surface not only ensure efficient water permeability, but also reduce the risk of clogging through self-cleaning properties. Polypropylene material is lightweight and flexible, easy to wrap and fix during construction, and is low in cost, recyclable and environmentally friendly. Compared with non-woven fabrics and natural fibers, it performs better in terms of chemical corrosion resistance, mechanical strength and lifespan, and is especially suitable for scenarios with coarse soil particles or requiring rapid drainage.

[0023] Reference Figure 3 As shown in this implementation scheme: the coarse filter layer 4 is made of non-woven geotextile. Non-woven geotextile, as a protective material for permeable pipe filtration, has the following outstanding advantages: it is made using a needle-punching process, with interwoven fibers forming a three-dimensional porous structure, effectively intercepting fine soil particles while maintaining excellent permeability. Its unique fiber network provides good planar drainage, quickly channeling water flow, and also possesses high tensile strength and tear resistance, able to withstand construction and soil pressure. Compared to woven materials, non-woven fabric is softer and more conforming, tightly wrapping the pipe and adapting to foundation deformation. The material is corrosion-resistant and resistant to microbial erosion; the standard service life of polypropylene is 5-15 years, with flexible weight selection. By combining different specifications, gradient filtration can be achieved, making it particularly suitable for environments with high clay content.

[0024] Reference Figure 2 and Figure 4 As shown in this embodiment: a guide ring 5 is fixed on the side of the mounting ring 2 near the permeable pipe body 1. The guide ring 5 is located at both ends inside the permeable pipe body 1. The guide ring 5 has a conical structure. By setting the guide ring 5, the liquid is guided so that the liquid can be better discharged.

[0025] Reference Figure 3 As shown in this embodiment: several reinforcing ribs 6 are fixed on the opposing surfaces of the mounting ring 2. The reinforcing ribs 6 are circumferentially distributed around the axis of the mounting ring 2. Several uniformly distributed reinforcing rings 7 are fitted around the outside of the coarse filter layer 4. The reinforcing rings 7 are fixed to the reinforcing ribs 6. Through the composite reinforcement scheme of the reinforcing ribs 6 and the reinforcing rings 7 working together, a longitudinal and radial skeleton support system is formed. This three-dimensional reinforcement structure plays a role in three dimensions: the axial reinforcing ribs 6 effectively resist the bending stress caused by uneven soil settlement and prevent longitudinal deformation of the pipeline; the radial reinforcing rings 7 constrain the ellipticity change of the pipeline and resist the radial compression caused by external soil pressure; the intersection of the two forms a spatial grid structure, which improves the compressive strength of the pipe body.

[0026] Working Principle: Combining a polypropylene filter mesh with non-woven geotextile to form a double-layer filtration structure fully leverages the synergistic advantages of the two materials, significantly improving the overall protective performance of the permeable pipe. This clearly defined hierarchical filtration design avoids rapid clogging caused by excessively fine materials and solves the problem of insufficient interception of fine particles by single coarse filter materials. In addition, the double-layer structure can buffer soil stress, adapt to foundation deformation, and extend the service life of the permeable pipe. Through the composite reinforcement scheme of reinforcing ribs 6 and reinforcing rings 7 working together, a longitudinal and radial skeleton support system is formed. This three-dimensional reinforcement structure works in three dimensions: the axial reinforcing ribs 6 effectively resist the bending stress caused by uneven soil settlement and prevent longitudinal deformation of the pipe; the radial reinforcing rings 7 constrain the ellipticity changes of the pipe and resist radial compression caused by external soil pressure; the intersection of the two forms a spatial grid structure, which enhances the compressive strength of the pipe body.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
