Description

Technical Field

[0001] This utility model relates to the field of paving device technology, and in particular to a modular combined permeable paving device. Background Technology

[0002] Modular permeable pavement is a key infrastructure component in sponge city construction, primarily used to address urban flooding and the heat island effect caused by paved surfaces. This device is composed of grid-like prefabricated unit modules made of high-strength recycled plastic or concrete, which are joined together to form a large-area permeable pavement system. Its core function is to enable rapid rainwater infiltration through a special structural design, while possessing sufficient load-bearing strength to meet the needs of sidewalks, parking lots, and other areas. The upper surface of the permeable pavement grid has evenly distributed permeable holes, and the interior features a multi-layered filtration structure. The bottom connects to a drainage system, forming a complete rainwater infiltration, filtration, and collection system. This paving method not only effectively replenishes groundwater but also reduces surface runoff and improves the urban microclimate. Currently, the product is widely used in urban squares, park trails, and residential roads, becoming an important technological means for modern ecological city construction.

[0003] Currently, permeable pavement grates exhibit two significant problems during long-term use: First, the drainage holes are prone to clogging. Although the drainage holes at the top of the frame improve permeability, fallen leaves, silt, and other impurities easily enter and clog the channels, severely impacting permeability efficiency. Second, maintenance is difficult. Similar to the bolted connections in building formwork, existing grates mostly use fixed connections, requiring complete dismantling to clear blockages, which is cumbersome and costly. These design flaws cause the performance of permeable pavement systems to decline over time, failing to sustain their intended ecological benefits. Therefore, improvements to the drainage structure design and ease of maintenance are urgently needed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a modular combined permeable pavement device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a modular permeable pavement device, including a permeable pavement frame. Two cross-shaped partition plates are fixedly connected to the inner wall of the permeable pavement frame. Two symmetrically arranged grooves are formed on the top surface of the permeable pavement frame. A drainage hole communicating with the grooves is formed through the bottom surface of the permeable pavement frame. An assembly frame is slidably connected to the top of the permeable pavement frame. A plurality of symmetrically arranged locking bolts are rotatably connected to one side of the assembly frame. The threaded portions of the locking bolts are threadedly connected to the permeable pavement frame. A plurality of linearly arrayed metal filters are embedded in the top of the permeable pavement frame, with each metal filter corresponding to one of the grooves.

[0007] Preferably, the top of the assembly frame is slidably connected with a plurality of symmetrically arranged plugs, the bottom surface of which is in contact with the top of the locking bolt.

[0008] Preferably, in any of the above solutions, the bottom surface of the assembly frame is fixedly connected with a number of symmetrically arranged support rods, and the inner wall of each groove is fixedly connected with two symmetrically arranged limiting sleeves, with the bottom end of the support rod inserted into the limiting sleeve.

[0009] Preferably, the top surface of the permeable pavement frame has a plurality of symmetrically arranged threaded holes, and the screw portions of the plurality of locking bolts are threadedly connected to the permeable pavement frame through the threaded holes.

[0010] Preferably, in any of the above solutions, the bottom surface of the assembly frame is fixedly connected with a number of symmetrically arranged positioning pins, and the top surface of the permeable paving frame is provided with a number of symmetrically arranged positioning holes, and the positioning pins are slidably connected to the permeable paving frame through the positioning holes.

[0011] Preferably, in any of the above embodiments, the outer surface of the partition plate is fixedly connected with a plurality of linear array reinforcing ribs, and the plurality of reinforcing ribs are perpendicular to the assembly frame.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. This permeable pavement device effectively solves the problem of easy clogging caused by impurities in traditional permeable pavements through the synergistic design of metal mesh and grooves. The metal mesh is embedded in the top of the permeable pavement frame, effectively intercepting larger impurities such as fallen leaves and silt, preventing them from entering the grooves. The cross-shaped structure of the partition plates forms multiple independent filtration zones, ensuring that even if some filters are clogged, other areas can still maintain normal drainage. The interconnected design of the drainage holes and grooves ensures that filtered rainwater can be discharged quickly. This multi-layer filtration system significantly improves the paving device's anti-clogging ability and extends the system maintenance cycle.

[0014] 2. The assembly frame of this device features a convenient disassembly structure, greatly simplifying the maintenance process. During operation, first remove the plug, then rotate the locking bolt to disengage it from the threaded hole. The locating pin remains within the locating hole, preventing the assembly frame from suddenly detaching. With the locking bolt fully loosened, the support rod is pulled out of the limit sleeve, allowing the entire assembly frame to be lifted, exposing the metal filter screen underneath for maintenance. The reinforcing ribs ensure the structural stability of the partition plate during disassembly. This design not only makes daily cleaning more convenient but also facilitates the replacement of metal filters of different specifications to adapt to different usage environments, extending the service life of the paving device and reducing maintenance costs.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 6As shown, a modular permeable pavement device includes a permeable pavement frame 1. Two cross-shaped partition plates 2 are fixedly connected to the inner wall of the permeable pavement frame 1. Two symmetrically arranged grooves 3 are opened on the top surface of the permeable pavement frame 1. Drainage holes 4 communicating with the grooves 3 are opened through the bottom surface of the permeable pavement frame 1. An assembly frame 5 is slidably connected to the top of the permeable pavement frame 1. Several symmetrically arranged locking bolts 6 are rotatably connected to one side of the assembly frame 5. The screw parts of the locking bolts 6 are all threadedly connected to the permeable pavement frame 1. Several linear arrays of metal filters 7 are embedded in the top of the permeable pavement frame 1. The metal filters 7 correspond to the grooves 3 respectively.

[0024] As an optional technical solution of this utility model, the top of the assembly frame 5 is slidably connected with several symmetrically arranged plugs 8. The bottom surface of the plugs 8 fits against the top of the locking bolts 6. The design of the plugs 8 effectively prevents debris and rainwater from entering the connection part of the locking bolts 6, avoids bolt corrosion and thread blockage, and ensures that the locking mechanism maintains reliable fastening performance for a long time. At the same time, the sliding connection method facilitates quick opening for maintenance operations.

[0025] As an optional technical solution of this utility model, the bottom surface of the assembly frame 5 is fixedly connected with several symmetrically arranged support rods 9, and the inner wall of each groove 3 is fixedly connected with two symmetrically arranged limiting sleeves 10. The bottom end of the support rod 9 is inserted into the limiting sleeve 10. The insertion and cooperation between the support rod 9 and the limiting sleeve 10 provides a stable support structure for the assembly frame 5, keeps the components accurately positioned during disassembly, prevents misalignment or tilting, and ensures the alignment accuracy during reassembly, thereby improving construction efficiency.

[0026] As an optional technical solution of this utility model, the top surface of the permeable pavement frame 1 is provided with a number of symmetrically arranged threaded holes 11, and the screw parts of a number of locking bolts 6 are all threadedly connected to the permeable pavement frame 1 through the threaded holes 11. The symmetrical arrangement of the threaded holes 11 and the cooperation of the locking bolts 6 form a uniformly distributed fastening point, so that the connection between the assembly frame 5 and the permeable pavement frame 1 is uniformly stressed, avoiding local stress concentration and improving the stability and load-bearing capacity of the overall structure.

[0027] As an optional technical solution of this utility model, the bottom surface of the assembly frame 5 is fixedly connected with a number of symmetrically arranged positioning pins 12, and the top surface of the permeable paving frame 1 is provided with a number of symmetrically arranged positioning holes 13. The positioning pins 12 are slidably connected to the permeable paving frame 1 through the positioning holes 13. The sliding cooperation between the positioning pins 12 and the positioning holes 13 realizes the precise positioning and guiding function during assembly, ensuring that each component is quickly and accurately aligned, greatly simplifying the installation process, and preventing positional deviation during use.

[0028] As an optional technical solution of this utility model, a number of linear array reinforcing ribs 14 are fixedly connected to the outer surface of the partition plate 2. The number of reinforcing ribs 14 are all perpendicular to the assembly frame 5. The linear array arrangement of the reinforcing ribs 14 significantly enhances the structural rigidity of the partition plate 2, enabling it to withstand greater vertical loads. At the same time, the perpendicular relationship with the assembly frame 5 optimizes the force transmission path and improves the overall stability of the entire paving device.

[0029] A modular permeable pavement device, the working principle of which is as follows:

[0030] 1): The metal filter screen 7 is embedded in the top of the permeable paving frame 1, which can effectively intercept larger impurities such as fallen leaves and mud and prevent them from entering the groove 3.

[0031] 2): The cross-shaped structure of partition 2 forms multiple independent filtration zones. Even if a local filter is clogged, other zones can still maintain normal drainage function.

[0032] 3) First, remove the plug 8, then rotate the locking bolt 6 to disengage it from the threaded hole 11. At this time, the locating pin 12 remains in the locating hole 13 to prevent the assembly frame 5 from suddenly falling off. As the locking bolt 6 is fully loosened, the support rod 9 is pulled out from the limit sleeve 10, and the assembly frame 5 can be lifted as a whole.

[0033] In summary, this modular permeable pavement device effectively solves the problem of easy clogging by impurities in traditional permeable pavements through the synergistic design of the metal filter 7 and the groove 3. The metal filter 7 is embedded in the top of the permeable pavement frame 1, effectively intercepting larger impurities such as fallen leaves and silt, preventing them from entering the groove 3. The cross-shaped structure of the partition plate 2 forms multiple independent filtration areas, ensuring that even if some filters are clogged, other areas can still maintain normal drainage. The interconnected design of the drainage hole 4 and the groove 3 ensures that filtered rainwater can be discharged quickly. This multi-layer filtration system significantly improves the anti-clogging ability of the pavement device and extends the system maintenance cycle. The assembly frame 5 adopts a convenient disassembly structure, greatly simplifying the maintenance process. During operation, first remove the plug 8, then rotate the locking bolt 6 to disengage it from the threaded hole 11. At this time, the positioning pin 12 remains in the positioning hole 13 to prevent the assembly frame 5 from suddenly falling off. As the locking bolt 6 is fully loosened, the support rod 9 is pulled out from the limiting sleeve 10, allowing the assembly frame 5 to be lifted as a whole, exposing the metal filter 7 underneath for maintenance. The reinforcing ribs 14 ensure the structural stability of the partition plate 2 during disassembly. This design not only makes daily cleaning more convenient but also facilitates the replacement of metal filters 7 of different sizes to adapt to different usage environments, extending the service life of the paving device and reducing maintenance costs.
