Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage, and particularly relates to a pipeline for preventing waterlogging in a sponge city. Background Art

[0002] As the name implies, a sponge city means that the city can absorb, store, infiltrate, and purify water when there is sufficient rainwater, and release and utilize the stored water when needed. The core of this concept lies in constructing a low-impact development rainwater system, enabling the city to respond naturally like a sponge when encountering rainfall, reducing runoff, alleviating the pressure on the urban drainage system, and at the same time realizing the resource utilization of rainwater.

[0003] For the construction of the rainwater system in a sponge city, drainage pipelines also need to be laid. However, the existing drainage pipelines are mostly circular and have water inlet and outlet at the ends. When the middle part of the pipeline is blocked, it is not convenient to clean, and the drainage efficiency is low, which is likely to cause waterlogging. Moreover, the existing drainage pipelines are ordinary water pipes, and when filled with water, they are prone to burst under the action of external shear force and extrusion, as well as when the drainage load is too large. Summary of the Utility Model

[0004] The utility model aims to solve the technical problems of low drainage efficiency of the existing pipelines, easy blockage and inconvenient cleaning, resulting in waterlogging, and easy pipe bursting. The purpose is to provide a pipeline for preventing waterlogging in a sponge city. By setting strip-shaped through grooves for drainage, the drainage points are distributed in a strip shape, with more and wider drainage points, improving the drainage efficiency, effectively avoiding waterlogging caused by untimely drainage, and at the same time facilitating the cleaning of the blocked parts of the pipeline, avoiding waterlogging caused by pipeline blockage, and having the characteristics of preventing waterlogging, not being prone to bursting, and long service life.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides a pipeline for preventing waterlogging in a sponge city, including:

[0007] An outer pipe body;

[0008] An inner pipe body, coaxially sleeved with the outer pipe body;

[0009] A buffer connecting member, connected between the inner wall of the outer pipe body and the outer wall of the inner pipe body;

[0010] Strip-shaped through grooves, penetrating through the outer pipe body and the inner pipe body and communicating with the internal cavity of the inner pipe body, and the strip-shaped through grooves are coaxial with the outer pipe body and the inner pipe body.

[0011] As a further technical solution of the utility model, the outer pipe body is a rigid pipe, and the inner pipe body is an elastic hose.

[0012] As a further technical solution of the present utility model, a buffer cavity is provided between the outer pipe body and the inner pipe body, and the buffer connecting members are uniformly arranged in the buffer cavity.

[0013] As a further technical solution of the present utility model, the buffer connecting member includes a buffer column, and both ends of the buffer column are respectively connected to the inner wall of the outer pipe body and the outer wall of the inner pipe body.

[0014] As a further technical solution of the present utility model, a first connecting portion is provided at the position where the buffer column is connected to the inner wall of the outer pipe body, and a second connecting portion is provided at the position where the buffer column is connected to the outer wall of the inner pipe body.

[0015] As a further technical solution of the present utility model, a layer of geotextile is covered on the outside of the outer pipe body.

[0016] As a further technical solution of the present utility model, the width of the strip-shaped through groove is 15 - 30 mm.

[0017] As a further technical solution of the present utility model, reinforcing ribs are further provided on the outer surface of the outer pipe body. The reinforcing ribs are concentric with the outer pipe body, and the reinforcing ribs are arranged at equal intervals on the outer surface of the outer pipe body.

[0018] As a further technical solution of the present utility model, the reinforcing rib is of an annular structure.

[0019] As a further technical solution of the present utility model, the reinforcing rib is of a rectangular structure.

[0020] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0021] 1. When the pipeline of the present utility model is in use and is arranged on the side of the road, when it rains, water flows into the strip-shaped through groove, and the strip-shaped through groove is used to communicate with the outside water for drainage. Compared with the existing structure with only one end water inlet, the strip-shaped structure makes the drainage points distributed in a strip shape, and the drainage points are more and wider, improving the drainage efficiency and drainage effect, and effectively avoiding waterlogging caused by untimely drainage.

[0022] 2. When the pipeline of the present utility model is blocked, the blockage is pushed to the drainage well by artificial through the strip-shaped through groove, and the blockage is taken out through the drainage well. Compared with the existing pipeline, it can more quickly locate the blockage position and clean it, thereby avoiding waterlogging caused by pipeline blockage.

[0023] 3. When the pipeline of the present utility model is subjected to external shear force to extrude the outer pipe body, the extrusion force is transmitted to the buffer connecting piece. At the same time, when the drainage load is too large, the water flow pressure directly acts on the inner pipe body and transmits the acting force to the buffer connecting piece. The relatively good elasticity of the buffer connecting piece is utilized to absorb and offset part of the extrusion force and the water flow acting force, so that the pipeline is not easily burst.

[0024] 4. The strength of the pipeline of the present utility model is increased by arranging reinforcing ribs on the outer surface of the pipeline, thereby increasing the service life of the pipeline.

[0025] 5. When the pipeline of the present utility model is in use, a layer of geotextile can be covered on the outer surface. The geotextile intercepts sundries, thereby further avoiding waterlogging caused by pipeline blockage. Brief Description of the Drawings

[0039] Embodiment 1

[0040] This embodiment provides a pipeline for preventing and controlling waterlogging in a sponge city, as Figures 1 - 4 shown, including an outer pipe body 100, an inner pipe body 200, a buffer connector 400, and a strip-shaped through groove 500;

[0041] The inner pipe body 200 is coaxially sleeved with the outer pipe body 100, and the outer pipe body 100 is sleeved outside the inner pipe body 200;

[0042] In one or more embodiments of the present utility model, the outer pipe body 100 is a rigid pipe, and the inner pipe body 200 is an elastic hose. The inner pipe body 200 is made of an elastic hose, which has good deformation ability. The outer pipe body 100 is a rigid pipe, which can withstand external extrusion, is not easily damaged, and has good supporting force at the same time. When the outer pipe body 100 is extruded by an external shear force or the drainage load is too large, the extrusion force and the water flow pressure are transmitted to the inner pipe body 200. Due to its good elasticity, the inner pipe body 200 can expand and absorb part of the extrusion force, so that the pipe is not easily burst.

[0043] The buffer connecting member 400 is connected between the inner wall of the outer pipe body 100 and the outer wall of the inner pipe body 200. As Figure 4 shown, there is a buffer cavity 300 between the outer pipe body 100 and the inner pipe body 200, and the buffer connecting members 400 are evenly arranged in the buffer cavity 300.

[0044] In one or more embodiments of the present utility model, the buffer connecting member 400 includes a buffer column 402, and both ends of the buffer column 402 are respectively connected to the inner wall of the outer pipe body 100 and the outer wall of the inner pipe body 200. When the outer pipe body 100 is extruded by an external shear force, the extrusion force is transmitted to the buffer connecting member 400. At the same time, when the drainage load is too large, the water flow pressure directly acts on the inner pipe body 200 and transmits the acting force to the buffer connecting member 400. The buffer connecting member 400 absorbs and offsets part of the extrusion force and the water flow acting force with its good elasticity, so that the pipe is not easily burst.

[0045] As a preferred embodiment, a first connecting portion 401 is provided at the position where the buffer column 402 is connected to the inner wall of the outer pipe body 100, and a second connecting portion 403 is provided at the position where the buffer column 402 is connected to the outer wall of the inner pipe body 200. By providing the first connecting portion 401 and the second connecting portion 403, the connection contact area between the buffer column 402 and the outer pipe body 100 and the inner pipe body 200 is increased, and the connection stability of the buffer column 402 is improved.

[0046] The strip-shaped through groove 500 penetrates through the outer pipe body 100 and the inner pipe body 200 and communicates with the inner cavity of the inner pipe body 200. The strip-shaped through groove 500 is coaxial with the outer pipe body 100 and the inner pipe body 200. By providing the strip-shaped through groove 500 in the present utility model, drainage is carried out by using the connection between the strip-shaped through groove 500 and the external water. Compared with the existing structure with only one end water inlet, the strip-shaped structure makes the drainage points distributed in a strip shape, with more and wider drainage points, improving the drainage efficiency and effect, effectively avoiding waterlogging caused by untimely drainage. At the same time, when the pipeline is blocked, the blockage can be pushed to the drainage well through the strip-shaped through groove 500 by manual, and the blockage can be removed through the drainage well. Compared with the existing pipelines, the blockage position can be found and cleared more quickly, thus avoiding waterlogging caused by pipeline blockage.

[0047] As a preferred embodiment, the width of the strip-shaped through groove 500 is 15 - 30 mm. If the width of the strip-shaped through groove 500 is too small, the drainage efficiency is relatively low; if the width of the strip-shaped through groove 500 is too large, it is easy to have an accident that objects fall into the strip-shaped through groove 500. Considering the actual use situation, setting the width of the strip-shaped through groove 500 to 15 - 30 mm can not only ensure good drainage efficiency but also prevent sundries from falling in.

[0048] In one or more embodiments of the present utility model, in order to further ensure that the strip-shaped through groove 500 will not be blocked due to fallen sundries, a layer of geotextile 700 is covered on the outside of the outer pipe body 100. When the pipeline of the present utility model is in use and is set on the side of the road, when it rains or the road surface is washed, water and road sundries enter the strip-shaped through groove 500. After setting the geotextile 700, the geotextile 700 intercepts the sundries, thus further avoiding waterlogging caused by pipeline blockage.

[0049] In one or more embodiments of the present utility model, reinforcing ribs 600 are further provided on the outer surface of the outer pipe body 100. The reinforcing ribs 600 are concentric with the outer pipe body 100, and the reinforcing ribs 600 are arranged at equal intervals on the outer surface of the outer pipe body 100. As Figure 3 shown, the reinforcing ribs 600 are of an annular structure. By providing the reinforcing ribs 600, the strength of the pipeline is increased, thereby increasing the service life of the pipeline.

[0050] Embodiment 2

[0051] This embodiment further illustrates the technical solution of the present utility model on the basis of Embodiment 1.

[0052] The difference between this embodiment and Embodiment 1 is that: as Figure 5As shown, the reinforcing rib 600 is of a rectangular structure, and the rest of the structure is the same as that of Embodiment 1. The rectangular reinforcing rib 600 can increase the contact area and further change the shape of the annular reinforcing rib 600, enhancing the strength of the pipeline.

[0053] Finally, it should be noted that the above specific embodiments are only used to elaborate in detail the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above description is only the specific implementation manner of the present invention and is not used to limit the protection scope of the present invention; although the present invention has been described in detail with reference to the foregoing specific embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements or improvements on some or all of the technical features; and these modifications, equivalent replacements and improvements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
