Description

Technical Field

[0001] This utility model relates to the field of drainage system technology, and in particular to a landscape manhole cover for urban roads. Background Technology

[0002] As a core component of the drainage system in municipal infrastructure, urban road manhole covers have undergone a gradual technological evolution from single-function to landscape integration. Early cast iron manhole covers were technology-driven, focusing on load-bearing capacity and theft prevention. With increasing demands for urban landscape aesthetics, the technological approach has gradually shifted towards surface decoration treatments (such as spraying and plating), structural vibration reduction optimization, and integrated permeability. In recent years, landscape manhole cover technology has developed into an interdisciplinary field integrating materials engineering, structural mechanics, and environmental design, with its core requirement being the synergistic improvement of engineering performance and urban aesthetics.

[0003] The current mainstream technical solution for urban road landscape manhole covers is as follows: high-strength cast iron manhole covers are used, and colored paint is sprayed onto the surface to create landscape patterns. Rubber shock-absorbing pads are embedded at the bottom of the manhole cover, and an array of permeable holes with a diameter of 5mm to 8mm are set around the perimeter. This solution achieves basic landscape integration through paint coloring, provides cushioning and shock absorption when vehicles drive over them, and the permeable holes meet the road drainage needs.

[0004] However, current mainstream technologies for urban road landscape manhole covers suffer from drawbacks such as insufficient flatness and fading of landscape patterns, resulting in poor pattern display. Specifically, an initial height difference often exists between the manhole cover and its base after installation. Under alternating vehicle loads, the accelerated creep of the rubber pad further widens this height difference, leading to insufficient flatness between the manhole cover surface and the road surface. This can easily generate noise and a noticeable bumpy feeling when vehicles pass over it.

[0005] Therefore, there is an urgent need for a new type of urban road landscape manhole cover to solve the problem of insufficient flatness of the current urban road landscape manhole covers. Utility Model Content

[0006] The main purpose of this utility model is to propose a landscape manhole cover for urban roads, which aims to solve the problem of insufficient flatness of current landscape manhole covers for urban roads.

[0007] To achieve the above objectives, this utility model proposes a landscape manhole cover for urban roads. The landscape manhole cover is installed on a manhole cover base on the road surface. It includes a decorative layer, a load-bearing layer, and a leveling component. The upper surface of the decorative layer is decorated with a decorative pattern. The top of the load-bearing layer is connected to the bottom of the decorative layer. The top of the leveling component is connected to the bottom of the load-bearing layer. The bottom of the leveling component has multiple sets of height adjustment structures. The bottom of each set of height adjustment structures is used to abut against the edge of the manhole cover base. Each set of height adjustment structures is used to independently adjust the height so that the upper surface of the decorative layer is flush with the road surface.

[0008] In one embodiment, the leveling component is annular, and multiple sets of height adjustment structures are evenly spaced at the bottom edge of the annular component; the manhole cover base is annular, and the bottom of the multiple sets of height adjustment structures abuts against the annular edge of the manhole cover base.

[0009] In one embodiment, the height adjustment structure includes adjustment bolts. The bottom of the leveling component is provided with multiple screw holes. The multiple adjustment bolts are threadedly connected to the multiple screw holes one by one. The adjustment bolts are used to rotate themselves to adjust the height of the leveling component, so that the upper surface of the decorative layer is flush with the road surface.

[0010] In one embodiment, the height adjustment stroke of the adjusting bolt is 2mm to 10mm.

[0011] In one embodiment, one of the top of the load-bearing layer and the bottom of the decorative layer is provided with a snap-fit ​​structure, and the other of the top of the load-bearing layer and the bottom of the decorative layer is provided with a slot, and the snap-fit ​​structure engages with the slot.

[0012] In one embodiment, a rubber ring is also provided on the top of the load-bearing layer; when the snap-fit ​​structure and the slot are engaged, the rubber ring abuts against the decorative layer.

[0013] In one embodiment, the load-bearing layer is a reinforced concrete structure, and a stainless steel mesh skeleton is embedded in the reinforced concrete structure.

[0014] In one embodiment, honeycomb-shaped permeable channels are formed inside the reinforced concrete structure.

[0015] In one embodiment, the pore size of the honeycomb permeable channels ranges from 2.0 mm to 5.0 mm.

[0016] In one embodiment, a light-emitting module is embedded inside the decorative layer; and / or, the upper surface of the decorative layer is made of ceramic material.

[0017] This invention achieves precise flatness adjustment for urban road landscape manhole covers through the coordinated use of a decorative layer, a load-bearing layer, and a leveling component. The decorative layer features decorative patterns on its upper surface for visual appeal. The load-bearing layer, acting as the main load-bearing component, withstands vehicle and pedestrian loads and provides stable support for the decorative layer, ensuring the manhole cover's durability and structural integrity. Furthermore, the leveling component incorporates multiple independently adjustable height adjustment structures at its bottom, directly abutting the edge of the manhole cover base. When the manhole cover is installed on the base, operators can independently adjust the height of each adjustment structure to compensate for the height difference between the upper surface of the decorative layer and the road surface. This multi-point independent adjustment mechanism ensures the upper surface of the decorative layer is as flush as possible with the road surface. This solution eliminates the bulging or sinking issues caused by uneven installation of traditional manhole covers, preventing safety hazards such as pedestrian tripping or vehicle bumps.

[0018] Overall, this solution uses multiple height adjustment structures of the leveling component to independently adjust the height, making the upper surface of the decorative layer as flush as possible with the road surface. This effectively improves the flatness of the manhole covers on urban roads and avoids safety hazards such as pedestrians tripping or vehicles bumping. Attached Figure Description

[0030] As a core component of the drainage system in municipal infrastructure, urban road manhole covers have undergone a gradual technological evolution from single-function to landscape integration. Early cast iron manhole covers were technology-driven, focusing on load-bearing capacity and theft prevention. With increasing demands for urban landscape aesthetics, the technological approach has gradually shifted towards surface decoration treatments (such as spraying and plating), structural vibration reduction optimization, and integrated permeability. In recent years, landscape manhole cover technology has developed into an interdisciplinary field integrating materials engineering, structural mechanics, and environmental design, with its core requirement being the synergistic improvement of engineering performance and urban aesthetics.

[0031] The current mainstream technical solution for urban road landscape manhole covers is as follows: high-strength cast iron manhole covers are used, and colored paint is sprayed onto the surface to create landscape patterns. Rubber shock-absorbing pads are embedded at the bottom of the manhole cover, and an array of permeable holes with a diameter of 5mm to 8mm are set around the perimeter. This solution achieves basic landscape integration through paint coloring, provides cushioning and shock absorption when vehicles drive over them, and the permeable holes meet the road drainage needs.

[0032] However, current mainstream technologies for urban road landscape manhole covers suffer from drawbacks such as insufficient flatness and fading of landscape patterns, resulting in poor pattern display. Specifically, an initial height difference often exists between the manhole cover and its base after installation. Under alternating vehicle loads, the accelerated creep of the rubber pad further widens this height difference, leading to insufficient flatness between the manhole cover surface and the road surface. This can easily generate noise and a noticeable bumpy feeling when vehicles pass over it.

[0033] Therefore, there is an urgent need for a new type of urban road landscape manhole cover to solve the problem of insufficient flatness of the current urban road landscape manhole covers.

[0034] To address the aforementioned problems, this utility model proposes a landscape manhole cover for urban roads.

[0035] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the urban road landscape manhole cover 1 is used to be installed on the manhole cover base of the road surface. The urban road landscape manhole cover 1 includes a decorative layer 11, a load-bearing layer 12 and a leveling component 13. The upper surface of the decorative layer 11 is provided with a decorative pattern; the top of the load-bearing layer 12 is connected to the bottom of the decorative layer 11; the top of the leveling component 13 is connected to the bottom of the load-bearing layer 12, and the bottom of the leveling component 13 is provided with multiple sets of height adjustment structures 131. The bottom of the multiple sets of height adjustment structures 131 is used to abut against the edge of the manhole cover base, and each set of height adjustment structures 131 is used to independently adjust the height so that the upper surface of the decorative layer 11 is flush with the road surface.

[0036] This invention achieves precise flatness adjustment of urban road landscape manhole cover 1 by employing the cooperation of a decorative layer 11, a load-bearing layer 12, and a leveling component 13. The upper surface of the decorative layer 11 features decorative patterns for visual appeal. The load-bearing layer 12, as the main load-bearing component, can withstand vehicle and pedestrian loads and provides stable support for the decorative layer 11, ensuring the durability and structural integrity of the manhole cover. Furthermore, the bottom of the leveling component 13 is equipped with multiple sets of height adjustment structures 131. These height adjustment structures 131 are independently adjustable, and their bottoms directly abut the edge of the manhole cover base. When the manhole cover is installed on the base, operators can compensate for the height difference between the upper surface of the decorative layer 11 and the road surface by independently adjusting the height of each set of height adjustment structures 131. The multi-point independent adjustment mechanism of multiple height adjustment structures 131 ensures that the upper surface of the decorative layer 11 is as flush as possible with the road surface. This solution eliminates the bulging or sinking phenomena caused by uneven installation of traditional manhole covers, preventing safety hazards such as pedestrian tripping or vehicle bumps.

[0037] Overall, this solution uses multiple height adjustment structures 131 of the leveling component 13 to independently adjust the height, making the upper surface of the decorative layer 11 as flush as possible with the road surface, effectively improving the flatness of the urban road landscape manhole cover 1, and avoiding safety hazards such as pedestrians tripping or vehicles bumping.

[0038] Please see Figure 1 and Figure 3 In an embodiment of this utility model, the leveling component 13 is annular, and multiple sets of height adjustment structures 131 are evenly spaced on the bottom edge of the annular shape of the leveling component 13; the manhole cover base is annular, and the bottom of the multiple sets of height adjustment structures 131 abuts against the annular edge of the manhole cover base.

[0039] In this embodiment, by designing the leveling component 13 as a ring, and simultaneously distributing multiple sets of height adjustment structures 131 evenly at intervals along the bottom edge of the ring, and correspondingly making the manhole cover base also ring-shaped, the bottoms of the multiple sets of height adjustment structures 131 can achieve uniform contact with the ring edge of the manhole cover base around the entire circumference. The ring-shaped structure design of the leveling component 13 and the uniform distribution of the height adjustment mechanism work together to ensure that the leveling component 13 can provide stable and uniform support force along the entire circumference for the load-bearing layer 12 and the decorative layer 11, effectively avoiding the problems of manhole cover deformation, warping, or stress concentration that may be caused by insufficient local support force or uneven force, and significantly improving the overall structural stability and load-bearing reliability of the manhole cover. Furthermore, due to the uniform distribution of the height adjustment structure 131, operators can more precisely and evenly compensate for any local settlement or unevenness of the annular edge of the manhole cover base when adjusting the height at each point. This allows for more accurate and convenient achievement of height consistency between the upper surface of the decorative layer 11 and the road surface, as well as overall flatness. The multi-point uniform distribution of this adjustment structure simplifies the installation and leveling operation, allowing adjustment only for areas that are too low or too high, and eliminating the safety risks of pedestrians tripping or vehicles bumping due to differences in manhole cover installation height. In addition, the multiple abutments between the bottoms of the multiple sets of height adjustment structures 131 and the annular edge of the manhole cover base also help the manhole cover base provide multi-point uniform and stable support for the urban road landscape manhole cover 1, effectively reducing the possibility of abnormal noise.

[0040] Please see Figure 3 and Figure 4 In an embodiment of this utility model, the height adjustment structure 131 includes an adjustment bolt 1311. The bottom of the leveling component 13 is provided with multiple screw holes. The multiple adjustment bolts 1311 are threadedly connected to the multiple screw holes one by one. The adjustment bolts 1311 are used to rotate themselves to adjust the height of the leveling component 13, so that the upper surface of the decorative layer 11 is flush with the road surface.

[0041] In this embodiment, the height adjustment structure 131 adopts a threaded connection between the adjusting bolt 1311 and the screw hole at the bottom of the leveling component 13. This threaded connection allows the operator to independently and precisely adjust the screw depth of the adjusting bolt 1311 relative to the screw hole of the leveling component 13 by rotating each adjusting bolt 1311 one by one, thereby conveniently and directly adjusting the height of the leveling component 13 at the corresponding position. This single-point independent adjustment mechanism based on the threaded pair allows the operator to make precise and controllable adjustments for each height adjustment point. Any slight local height difference that may exist at the edge of the manhole cover base can be effectively compensated by the precise rotation of the adjusting bolt 1311 at the corresponding position, which greatly improves the flexibility of operation and adjustment accuracy. By independently adjusting each adjusting bolt 1311, it can be ensured that the upper surface of the decorative layer 11 achieves a height consistency with the road surface and a level state of the overall plane height, effectively eliminating the problem of protrusions or depressions caused by uneven installation. In addition, the threaded connection itself has good self-locking and stability. After the adjusting bolt 1311 is set at the height and installed, its tight engagement with the threaded hole can provide a stable mechanical locking effect, so that the height of each adjustment point can be reliably maintained. It is not easy to loosen or shift due to external forces during vehicle rolling or daily use, thereby continuously ensuring the stable support effect of the leveling component 13 and helping to suppress abnormal noise caused by loose parts. Ultimately, it ensures the flatness and safety of the urban road landscape manhole cover 1 for long-term use.

[0042] In one optional implementation, the height adjustment stroke of the adjusting bolt 1311 is 2mm to 10mm. By limiting the height adjustment stroke of the adjusting bolt 1311 to the range of 2mm to 10mm, the lower limit of 2mm ensures that the height adjustment structure 131 has a sufficiently fine minimum adjustment range. This allows operators to precisely compensate for and fine-tune minor settlements or unevenness at the edge of the manhole cover base, thereby controlling the flatness of the upper surface of the decorative layer 11 with the road surface. Simultaneously, the upper limit of 10mm provides a sufficient maximum adjustment range, effectively compensating for and covering significant height differences caused by common settlements or installation errors in the manhole cover base. This ensures that the adjusting bolt 1311 has sufficient stroke to cope with various different settlement requirements that may occur in actual construction environments, significantly improving the applicability and reliability of this height adjustment scheme under complex real-world conditions. This height travel range is an optimal result that balances fine adjustment capability with sufficient adjustment margin. It avoids the problem that too small a travel may not meet the actual compensation requirements, and also prevents the drawbacks of too large a travel causing the adjusting bolt 1311 to be too long, affecting the structural compactness, increasing manufacturing costs, or potentially reducing structural stability.

[0043] In addition, as an optional implementation, the bottom of the leveling component 13 can be provided with 12 screw holes, and the number of adjusting bolts 1311 can be 12. The 12 adjusting bolts 1311 are threadedly connected to the 12 screw holes one by one, thereby using a sufficient number of adjusting bolts 1311 to adjust the height of the corresponding position of the leveling component 1312, thereby improving the precision of the adjustment and making the upper surface of the decorative layer 11 as flush as possible with the road surface. Of course, the number of screw holes and adjusting bolts 1311 of the leveling component 13 can also be increased or decreased according to the actual leveling requirements, and the number of screw holes and adjusting bolts 1311 is not limited here. In addition, for example, the adjusting bolts 1311 can be threaded bolts with a nominal diameter of 16mm, i.e., M16 bolts, and the thread accuracy grade can be 6g, and the corresponding screw hole thread accuracy grade is 6H. Of course, bolts and screw holes with other nominal diameters and thread accuracy grades can also be used, which will not be elaborated here.

[0044] As an optional implementation, the leveling component 13 can be made of a composite material of high-strength aluminum alloy and nitrile rubber to ensure the structural strength and load-bearing capacity of the leveling component 13. Of course, the leveling component 13 can also be made of other materials, and the material of the leveling component 13 is not limited here.

[0045] Because the surface coating of manhole covers is affected by ultraviolet radiation and vehicle friction, the annual fading rate of the patterned coating on the surface of manhole covers is ≥15%, easily resulting in noticeable fading and poor pattern display. To solve the above problem, please refer to... Figure 3 and Figure 4 In an embodiment of this utility model, one of the top of the load-bearing layer 12 and the bottom of the decorative layer 11 is provided with a snap-fit ​​structure 14, and the other of the top of the load-bearing layer 12 and the bottom of the decorative layer 11 is provided with a slot 15, and the snap-fit ​​structure 14 and the slot 15 are engaged.

[0046] In this embodiment, a snap-fit ​​structure 14 and a slot 15 are respectively provided on the top of the load-bearing layer 12 and the bottom of the decorative layer 11, respectively. The snap-fit ​​between the two achieves a convenient detachable connection, so that the decorative layer 11 can be independently disassembled, maintained, or replaced, thereby ensuring the pattern display effect of the decorative layer 11. Specifically, the engagement of the snap-fit ​​structure 14 and the slot 15 can form a firm and reliable physical lock at the moment of connection, ensuring that the decorative layer 11 is firmly fixed on the load-bearing layer 12. This effectively prevents the decorative layer 11 from accidentally shifting, loosening, or falling off relative to the load-bearing layer 12 during the use of the urban road landscape manhole cover 1 (such as when a vehicle runs over it or a pedestrian steps on it), significantly ensuring the stability and reliability of the overall structure of the manhole cover. Furthermore, the snap-fit ​​connection method offers high efficiency and convenience. Compared to other connection and fixing methods such as threaded connections, the snap-fit ​​connection method requires no additional connectors or complex tools during installation. Simply align the snap-fit ​​structure 14 with the slot 15 and apply pressure to complete the quick assembly, greatly simplifying the installation of the decorative layer 11 and reducing installation difficulty and time costs. When it is necessary to replace or maintain the decorative layer 11, disengaging the snap-fit ​​is also convenient, allowing for non-destructive or low-destructive disassembly of the decorative layer 11. This makes the replacement of the decorative layer 11 more convenient and efficient, further reducing maintenance costs and workload. After replacing the decorative layer 11 or maintaining the decorative pattern on the decorative layer 11, the new decorative layer 11 has a decorative pattern that has not faded, thus ensuring the display effect of the pattern on the decorative layer 11.

[0047] As an optional implementation, the snap-fit ​​structure 14 can be set as a spring snap-fit, thereby utilizing the elastic characteristics of the spring snap-fit ​​to make it easy for the spring snap-fit ​​to extend into the slot 15 and form a snap-fit ​​engagement with the slot 15, and to be easy to disassemble during disassembly, thus improving the convenience of disassembly and assembly.

[0048] Please see Figure 3 and Figure 4 In an embodiment of this utility model, a rubber ring 121 is also provided on the top of the load-bearing layer 12; when the buckle structure 14 and the slot 15 are engaged, the rubber ring 121 abuts against the decorative layer 11.

[0049] In this embodiment, by additionally providing a rubber ring 121 on the top of the load-bearing layer 12, and having it engage with the decorative layer 11 through the snap-fit ​​structure 14 and the slot 15, the rubber ring 121's elastic properties can achieve a buffering and vibration reduction effect. Furthermore, the rubber ring 121 creates a sealed connection between the decorative layer 11 and the load-bearing layer 12, preventing external water and sediment from accumulating between them. Specifically, the rubber ring 121, as an elastic medium between the load-bearing layer 12 and the decorative layer 11, further compensates for or fills any small gaps or manufacturing tolerances that may exist between the bottom of the decorative layer 11 and the top of the load-bearing layer 12, based on the snap-fit ​​structure providing the main connection and fixation. Furthermore, the elastic deformation characteristics of the rubber ring 121 can effectively absorb and attenuate the impact or vibration stress generated on the decorative layer 11 by vehicles running over it or pedestrians passing by, preventing vibration from being directly transmitted to the decorative layer 11 through the load-bearing layer 12. This significantly reduces noise that may be generated between different structural components due to hard contact or fretting friction, thus reducing environmental noise. In addition, the damping and buffering effect of the rubber ring 121 reduces the small reciprocating vibrations or impact loads acting on the load-bearing layer 12, thereby effectively reducing the risk of wear or loosening caused by fretting between different components, extending the service life and reliability of the snap-fit ​​structure, and indirectly protecting the structural integrity of the bottom of the decorative layer 11. Moreover, the elastic contact formed by the rubber ring 121 at the bottom of the decorative layer 11 and the joint area of ​​the load-bearing layer 12 provides a certain degree of flexible sealing effect, which helps to prevent pollutants such as road surface water and mud from seeping into the gap between the decorative layer 11 and the load-bearing layer 12 through the joint, reducing the risk of corrosion caused by internal dirt accumulation or the difficulty of cleaning during disassembly and maintenance. The rubber ring 121 has the advantages of simple structure and low cost. Its elastic buffering and vibration reduction, flexible sealing and gap filling functions complement the rigid connection of the snap-fit ​​structure 14-slot 15, thereby enhancing the overall durability, quiet use and convenient maintenance of the urban road landscape manhole cover 1.

[0050] In an embodiment of this utility model, the load-bearing layer 12 is made of reinforced concrete, and a stainless steel skeleton mesh is embedded in the reinforced concrete structure.

[0051] In this embodiment, the load-bearing layer 12 adopts a reinforced concrete structure with an embedded stainless steel mesh, thereby utilizing the excellent compressive strength, wear resistance, and weather resistance of the concrete matrix to effectively bear road loads and provide structural stability. The stainless steel mesh embedded in the reinforced concrete structure acts as a reinforcing support structure, significantly improving the tensile strength and toughness of the concrete, compensating for its brittleness, and effectively dispersing loads and inhibiting crack propagation through its mesh structure, thus enhancing overall impact and crack resistance. By employing a reinforced concrete structure, this load-bearing layer 12 ensures its core load-bearing performance while also considering economy and service life.

[0052] As an optional implementation method, the concrete in the reinforced concrete structure can be basalt fiber reinforced concrete, with a mix ratio of cement:sand:basalt fiber = 1:2:0.15.

[0053] Please see Figure 3 and Figure 4 In an embodiment of this utility model, honeycomb-shaped permeable channels 122 are formed inside the reinforced concrete structure.

[0054] In this embodiment, by forming honeycomb-shaped permeable channels 122 inside the reinforced concrete structure, these channels provide an effective pathway for rainwater or road surface water to quickly infiltrate the load-bearing layer 12, significantly reducing water accumulation in the load-bearing layer 12. The honeycomb-shaped permeable channels have a uniformly dense geometric characteristic, which, while providing excellent permeability, efficiently disperses and transfers loads, ensuring that the load-bearing layer 12 maintains sufficient compressive and impact resistance even when permeable, and effectively avoids the weakening of structural strength caused by large-area pores.

[0055] In one optional implementation, the pore size of the honeycomb permeable channels 122 ranges from 2.0 mm to 5.0 mm. By setting the lower limit of the pore size of the honeycomb permeable channels 122 to 2.0 mm, effective water conduction is ensured, allowing rainwater or surface water to seep through smoothly. This avoids the risk of small pores being clogged by fine sediment, which would cause the permeability to fail. Furthermore, by controlling the upper limit of the pore size of the honeycomb permeable channels 122 to 5.0 mm, the density and integrity of the reinforced concrete structure are maintained. This effectively prevents excessively large pores from weakening the bonding force between aggregates, ensuring the compressive strength and impact resistance of the load-bearing layer 12. This pore size range balances permeability efficiency and structural strength, ensuring both long-lasting and efficient drainage while maintaining the mechanical properties and structural strength of the reinforced concrete structure.

[0056] In an embodiment of this utility model, a light-emitting module (not shown in the figure) is embedded inside the decorative layer 11; and / or, the upper surface of the decorative layer 11 is made of ceramic material.

[0057] In this embodiment, by embedding a light-emitting module inside the decorative layer 11, the light-emitting module provides an enhanced lighting effect, improving the aesthetics of the landscape and increasing the clarity of viewing the decorative layer 11 in dark environments. Furthermore, by using ceramic material for the upper surface of the decorative layer 11, it achieves high hardness to resist wear and tear from passing vehicles and mud, thus ensuring the long-term display effect of the pattern on the upper surface of the decorative layer 11.

[0058] Correspondingly, when the upper surface of the decorative layer 11 is made of ceramic material, the pattern on the upper surface of the decorative layer 11 can be engraved on the decorative layer 11 by means of laser engraving or other methods, thereby ensuring the engraving effect and durability of the pattern.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
