The utility model provides a modular urban pipe network, which relates to the technical field of modular pipe networks, and comprises a concrete bottom plate, a concrete side plate is fixed at the top of the concrete bottom plate, and a bottom plate top limit moment is fixed at the top of the concrete bottom plate. The construction process is complex and long in time consumption, so that the construction cost is increased, and great inconvenience is brought to daily life and travel of citizens due to long-time road occupation, for example, in a pipe network system without adopting modular design, large-area road excavation is needed even if small-range maintenance work is carried out, and the construction period is shortened. In addition, due to the non-modular design, the quick response under the emergency situation becomes difficult, for example, when leakage or other emergency situations occur, the problem is difficult to position quickly, and effective measures are difficult to take for solving the problem.

Description

Technical Field

[0001] This utility model relates to the field of modular pipeline technology, and in particular to a modular urban pipeline network. Background Technology

[0002] Urban pipeline networks refer to the underground pipeline systems installed in cities to transport various media (such as water, gas, and electricity). They include various types of networks such as water supply, drainage, gas supply, and heating. These networks collectively constitute the city's infrastructure network, providing basic guarantees for the city's operation and residents' lives. Urban pipeline networks are an indispensable part of urban infrastructure, and smart pipeline networks represent an important direction for their future development. With continuous technological advancements and sustained policy support, smart pipeline networks will play an increasingly important role in improving urban operational efficiency, ensuring residents' quality of life, and promoting sustainable development.

[0003] In existing technologies, urban pipeline systems often lack a modular design concept during design and implementation. This is particularly evident when pipelines need to be laid or repaired, especially when pipeline work is carried out under urban roads such as pedestrian crossings and green belts. Due to the lack of pre-planned modular design, the construction process is complex and time-consuming. This not only increases construction costs but also causes great inconvenience to citizens' daily lives and travel due to prolonged road closures. For example, in pipeline systems without modular design, even small-scale maintenance work requires large-scale road excavation, which in turn affects traffic flow and pedestrian safety over a wider area. In addition, non-modular design also makes rapid response in emergencies extremely difficult. For example, in the event of a leak or other emergency, it is difficult to quickly locate the problem and take effective measures to solve it. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular urban pipe network.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a modular urban pipe network, including a concrete base slab, a concrete side plate fixed to the top of the concrete base slab, a base slab top limit moment fixed to the top of the concrete base slab, a modular grid fixed to the top of the concrete base slab, a lower limit groove opened at the bottom of the modular grid, the inner wall of the lower limit groove nesting with the surface of the base slab top limit moment, a through pipe opened on the inner wall of the modular grid, an upper limit member fixed to the top of the modular grid, the surface of the upper limit member nesting with the inner wall of the lower limit groove, and four corner cut edges opened at the edges of the modular grid.

[0006] Preferably, a side top extension plate is fixed to the top of the concrete side plate, and a double-sided sliding groove is formed on one side of the side top extension plate. A sliding bearing plate is slidably connected to the inner wall of the double-sided sliding groove. In the prior art, concrete pouring is a common step in the laying of urban pipeline networks to fix the position of the pipeline and ensure its stability. However, this process also brings significant challenges, especially when it is necessary to adjust or repair the internal modular grid. Once the concrete is poured and cured, workers will face great difficulty in modifying the internal modular grid. This is because the solid nature of concrete makes any attempt to move or adjust the underlying modules complex and time-consuming. This design limitation leads to low efficiency in maintenance work. When repairs or upgrades are needed, workers often have to take destructive measures. For example, excavating the road surface and breaking up the existing concrete structure to access the underlying modular grid not only increases labor intensity and extends maintenance time, but also further exacerbates the disruption to urban traffic and daily life. In addition, frequent damage and reconstruction increase maintenance costs and burden the city's economic operation. To address these issues, this utility model adopts the method of installing a sliding bearing plate. Before pouring concrete, the sliding bearing plate is slid into the double-sided chute, so that the sliding bearing plate bears the concrete during pouring, preventing pressure on the underlying modular grid and causing it to move. At the same time, when the concrete covering needs to be removed, the concrete at the contact point between the sliding bearing plate and the side top extension plate is simply knocked off, and then the sliding bearing plate is directly cut out, thereby greatly reducing the number of procedures and improving work efficiency.

[0007] Preferably, an outer limiting triangular member is fixed to one side of the concrete side plate, and an inner limiting triangular member is fixed to the other side of the concrete side plate. In the prior art, since the concrete side plate is usually buried underground during the pipeline laying process, although this approach can provide necessary structural support for the pipeline, it also brings some potential problems. Over time and due to environmental factors such as soil settlement, moisture changes, or changes in ground load, the surrounding soil will exert uneven pressure on the concrete side plate. This pressure can cause the concrete side plate to deform or tilt, thereby compressing the module grid installed on it. When the module grid is subjected to uneven pressure from the deformed concrete side plate, it will affect the stability of the entire pipeline system, specifically manifested as pipeline displacement. This not only affects the functional performance of the pipeline but also increases leakage and other safety risks. In addition, pipeline displacement also leads to conflicts with other underground facilities, thus requiring more frequent maintenance and repair work. To address these problems, this utility model uses the installation of an outer limiting triangular member to solve the problem. By cooperating with the inner limiting triangular member, the stability of the concrete side plate is greatly increased, preventing it from tilting and thus improving the product's service life.

[0008] Preferably, the upper limit piece has top side pinch grooves on both sides, which facilitates handling by staff and improves user experience.

[0009] Preferably, the module grid has side tight grooves on both sides, which increases the friction between the module grids, prevents displacement caused by vibration, and improves stability.

[0010] Preferably, the top of the module grid has a reserved groove, which allows for space to be reserved for thermal expansion and contraction, thereby improving the product's service life.

[0011] Preferably, the top two edges of the bottom plate are provided with slits to allow for thermal expansion and contraction, thereby improving the product's service life.

[0012] Beneficial effects:

[0013] 1. In existing technologies, urban pipeline systems often lack a modular design concept during design and implementation. This is particularly evident when pipelines need to be laid or repaired, especially when working under urban roads such as pedestrian crossings and green belts. The lack of pre-planned modular design leads to complex and time-consuming construction processes. This not only increases construction costs but also causes significant inconvenience to citizens' daily lives and travel due to prolonged road closures. For example, in pipeline systems without modular design, even small-scale repairs require large-scale road excavation, affecting traffic flow and pedestrian safety over a wider area. Furthermore, non-modular design makes rapid response in emergencies extremely difficult. For instance, in the event of leaks or other emergencies, it is difficult to quickly locate the problem and take effective measures to resolve it. To address this problem, this utility model employs a modular grid installation method. Before laying the pipeline, the lower limit of the bottommost modular grid is embedded into the top limit of the concrete base slab. Then, the lower limits of the upper modular grids are successively nested with the lower limits of the lower modular grids. Since the modular grids can be mass-produced and pre-deployed at the laying site, and are easy to install and not prone to collapse, workers can quickly construct the pipeline grid on the existing concrete base and side slabs. This significantly shortens the construction period and reduces the time spent on urban roads. If a problem occurs in the pipeline, due to the modular grid's restriction on the pipeline, workers can easily remove the pipeline through a nearby inspection well, and then disassemble the upper modular grids for inspection and replacement, thereby improving production efficiency.

[0014] 2. In existing technologies, concrete pouring is a common step in the laying of urban pipeline networks to fix the pipe positions and ensure their stability. However, this process also presents significant challenges, especially when adjustments or repairs to the internal modular grid are needed. Once the concrete is poured and cured, workers face considerable difficulty in altering the internal modular grid. This is because the solid nature of concrete makes any attempt to move or adjust the underlying modules complex and time-consuming. This design limitation leads to low efficiency in maintenance work. When repairs or upgrades are required, workers often need to take destructive measures, such as re-excavating the road surface and breaking up existing concrete structures, to access the underlying modules. The modular grid structure not only increases labor intensity and extends maintenance time, but also exacerbates disruption to urban traffic and daily life. Furthermore, frequent damage and reconstruction increase maintenance costs and burden the city's economic operation. To address these issues, this utility model adopts a sliding bearing plate installation method. Before pouring concrete, the sliding bearing plate is slid into the double-sided groove, allowing it to bear the concrete during pouring and preventing pressure on the underlying modular grid that could cause it to move. When workers need to remove the concrete covering, they only need to knock off the concrete at the contact point between the sliding bearing plate and the side top extension plate, and then directly slide out the sliding bearing plate, thereby greatly reducing the number of procedures and improving work efficiency.

[0015] 3. In existing technologies, concrete side panels are typically buried underground during pipeline laying. While this provides necessary structural support for the pipeline, it also introduces potential problems. Over time and due to environmental factors such as soil settlement, moisture changes, or variations in ground load, the surrounding soil exerts uneven pressure on the concrete side panels. This pressure can cause deformation or tilting of the concrete side panels, which in turn compresses the module grids installed on them. When the module grids are subjected to uneven pressure from the deformed concrete side panels, the stability of the entire pipeline system is affected, specifically, pipeline displacement. This not only affects the functionality of the pipeline but also increases leakage and other safety risks. Furthermore, pipeline displacement can lead to conflicts with other underground facilities, requiring more frequent maintenance and repair work. To address these issues, this invention employs the installation of external limiting triangular members. By cooperating with internal limiting triangular members, the stability of the concrete side panels is significantly increased, preventing tilting and extending the product's service life.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6A modular urban pipeline network includes a concrete base slab 1, a concrete side plate 101 fixed to the top of the concrete base slab 1, a base slab top limit moment 2 fixed to the top of the concrete base slab 1, a modular grid 201 fixed to the top of the concrete base slab 1, a lower limit groove 204 opened at the bottom of the modular grid 201, the inner wall of the lower limit groove 204 nested with the surface of the base slab top limit moment 2, a through pipe 202 opened on the inner wall of the modular grid 201, an upper limit member 203 fixed to the top of the modular grid 201, the surface of the upper limit member 203 nested with the inner wall of the lower limit groove 204, and four corner cut edges 205 opened at the edges of the modular grid 201. A side top extension plate 3 is fixed to the top of the concrete side plate 101. A double-sided sliding groove 301 is provided on one side of the side top extension plate 3, and a sliding bearing plate 302 is slidably connected to the inner wall of the double-sided sliding groove 301. Concrete pouring is a common step in the laying of urban pipeline networks to fix the pipe position and ensure its stability. However, this process also brings significant challenges, especially when adjustments or repairs to the internal modular grid 201 are needed. Once the concrete is poured and cured, workers face great difficulty in modifying the internal modular grid 201. This is because the solid nature of concrete makes any attempt to move or adjust the underlying modules complex and time-consuming. This design limitation leads to low efficiency in maintenance work. When repairs or upgrades are needed, workers often have to take destructive measures, such as re-laying... Excavating the road surface and breaking down existing concrete structures to access the underlying modular grid 201 not only increases labor intensity and extends maintenance time, but also further exacerbates disruption to urban traffic and daily life. In addition, frequent damage and reconstruction increase maintenance costs and burden the city's economic operation. The solution is to install a sliding bearing plate 302. Before pouring concrete, the sliding bearing plate 302 is slid into the double-sided chute 301, allowing it to bear the concrete during pouring and preventing pressure on the underlying modular grid 201 that could cause it to move. When workers need to remove the concrete covering, they only need to knock off the concrete at the contact point between the sliding bearing plate 302 and the side top extension plate 3, and then directly cut out the sliding bearing plate 302, thereby greatly reducing the number of procedures and improving work efficiency.

[0028] An outer limiting triangular member 4 is fixed to one side of the concrete side plate 101, and an inner limiting triangular member 401 is fixed to the other side. Since the concrete side plate 101 is typically buried underground during pipeline laying, while this provides necessary structural support for the pipeline, it also introduces some potential problems. Over time and due to environmental factors such as soil settlement, moisture changes, or variations in ground load, the surrounding soil can exert uneven pressure on the concrete side plate 101. This pressure can cause deformation or tilting of the concrete side plate 101, which in turn can damage the module grid 201 installed on it. When the modular grid 201 is subjected to uneven pressure from the deformed concrete side plate 101, the stability of the entire pipeline system is affected, specifically by pipeline displacement. This not only affects the functional performance of the pipeline but also increases leakage and other safety risks. Furthermore, pipeline displacement can lead to conflicts with other underground facilities, requiring more frequent maintenance and repair work. This is addressed by installing external limiting triangular members 4. The cooperation between the external limiting triangular members 4 and the internal limiting triangular members 401 significantly increases the stability of the concrete side plate 101, preventing tilting and extending the product's service life. The upper limit fitting 203 has top and side pinch grooves 5 on both sides, facilitating handling and improving user experience. The modular grid 201 has side tight grooves 6 on both sides, increasing friction between the modular grids 201 to prevent displacement caused by vibration and improving stability. The modular grid 201 has a top reserved groove 7 at the top, allowing space for thermal expansion and contraction, further extending the product's service life. The top two edges of the bottom plate limit moment 2 are cut with chamfered edges to allow for thermal expansion and contraction, thereby improving the product's service life.

[0029] The working principle of this utility model is as follows: Before laying the pipeline, the lower limit groove 204 of the bottom module grid 201 is embedded into the top limit moment 2 of the concrete base plate 1. Then, the lower limit groove 204 of the upper module grid 201 is nested with the lower limit groove 204 of the lower module grid 201 step by step. Since the module grid 201 can be mass-produced in the project and laid in advance, and is easy to install and not easy to collapse, the workers can quickly build a concrete grid for pipeline placement on the existing concrete base plate 1 and concrete side plate 101 using the module grid 201. This greatly shortens the construction period and reduces the time occupied by urban roads. When a problem occurs in a certain part of the pipeline, due to the restriction of the pipeline by the module grid 201, the workers can easily pull out the pipeline through the nearby maintenance well, and then the upper module grid 201 is disassembled step by step for inspection and replacement.
