[0003] The existing paving method usually involves installing bricks on the soil, with a permeable layer underneath. However, due to the poor support performance of the soil, the bricks will shift during long-term trampling, and the drainage performance is not high, which can easily lead to water accumulation and reduce the comfort of people walking. Utility Model Content

However, due to the poor support performance of the soil, the bricks will shift during long-term trampling, and the drainage performance is not high, which easily leads to water accumulation and reduces the comfort of people walking. This paper proposes a paving structure for municipal road engineering.

[0005] A municipal road paving structure includes: a bottom support block, wherein the top surface of the bottom support block has a pre-set array of grooves arranged at equal intervals;

[0008] The paving brick unit has a positioning boss on its bottom surface that mortise and tenon with the top surface of the base, and the extensions on both sides cover the top surface of the ceramsite filling module to form a cantilever structure.

[0009] The soil layer fills the surface of the base and the ceramsite module up to the bottom of the paving bricks, and penetrates into the gaps between the paving bricks to form a joint caulking layer;

[0010] Multiple drain pipes are located inside the bottom support block, and both ends of the multiple drain pipes are fixedly connected to water guide pipes, one end of which is fixedly connected to the main drain pipe.

[0011] In one embodiment, a plurality of the ceramsite filling modules are respectively disposed above a plurality of the drainage pipes, and the surface of each of the plurality of ceramsite filling modules is covered with a mesh screen.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The following is combined with Figures 1-5 This utility model describes the paving structure for municipal road engineering.

[0030] In one embodiment, a municipal road paving structure includes: a bottom support block 100, multiple bases 101, a ceramsite filling module 200, paving brick units 400, a soil cover layer 500, and multiple drainage pipes 300. The top surface of the bottom support block 100 has a pre-set array of equally spaced grooves. The multiple bases 101 are fixedly connected to the groove array above the bottom support block 100 by anchors. The ceramsite filling module 200 is formed by pressing lightweight ceramsite with a particle size of 20-40mm using an inorganic binder and filling the grooves. The gap between adjacent base 101, the bottom surface of the paving brick unit 400 is provided with a positioning boss that mortise and tenon fits with the top surface of the base 101, the two side extensions cover the top surface of the ceramsite filling module to form a cantilever structure, the soil layer 500 fills the surface of the base 101 and the ceramsite module to the bottom of the paving brick, and seeps into the gap of the paving brick to form a joint layer, multiple drainage pipes 300 are all located inside the bottom support block 100, and both ends of the multiple drainage pipes 300 are fixedly connected to water guide pipes 301, one end of the water guide pipe 301 is fixedly connected to the main drainage pipe;

[0031] In this embodiment, the top surface of the bottom support block 100 has a pre-set array of grooves arranged at equal intervals. The precast concrete base 101 is fixedly connected to the bottom support block 100 using stainless steel anchors. The ceramsite filling module 200 is formed by pressing lightweight ceramsite with a particle size of 20-40mm with an inorganic binder. The module size matches the spacing of the base 101. A flow channel 202 is set at the bottom and filled with a 10-15mm gravel layer. The paving brick unit 400 is made of permeable concrete. The extensions on both sides form a cantilever structure that covers the top surface of the ceramsite module.

[0032] The topsoil layer 500 is composed of a mixture of sand and gravel and organic improved soil, which seeps into the gaps of the paving bricks to form a 3-5mm joint filling layer. The joint filling material contains an acrylic emulsion modifier. The bottom support block 100 has a corrugated drainage pipe 300 buried inside, and both ends are connected to the main drainage pipe through water guide pipes 301. This structure integrates a tiered drainage system with ceramsite filtration, gravel diversion, and pipe discharge, a permeable paving system, and intelligent lighting components to achieve multiple functions such as efficient drainage, load distribution, and ecological permeability, which greatly improves the user experience.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, multiple ceramsite filling modules 200 are respectively installed above multiple drainage pipes 300. Each of the multiple ceramsite filling modules 200 is covered with a net 201. Each of the multiple bases 101 is fixedly connected with a support column 102. Each of the multiple support columns 102 is covered with a base block 402. The upper part of the base block 402 is fixedly connected to the lower part of the paving brick unit 400.

[0034] In this embodiment, the top surface of the expanded clay filling module 200 is flush with the top surface of the base 101, forming a continuous support surface. The mesh 201 covering the surface of the expanded clay filling module 200 is made of woven stainless steel wire, which allows rainwater to penetrate while preventing the loss of expanded clay. The pillars 102 welded above the multiple bases 101 are galvanized steel pipes with an epoxy powder coating. They are bolted to the paving brick unit 400 through the base block 402. The base block 402 is made of aluminum alloy and has a sliding sleeve at the bottom that matches the outer diameter of the pillar 102. The sleeve is fitted with a polytetrafluoroethylene anti-friction pad to ensure that the paving brick unit 400 can freely expand and contract when deformed by temperature. The mesh 201 and the gravel layer form a dual filtration system. Combined with the limiting effect of the pillar 102, the vertical deformation of the paving brick unit 400 is small when it is subjected to load, while maintaining water permeability, thus achieving an organic unity of structural stability and ecological function.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, photosensitive lamps 401 are fixedly connected to both sides of the interior of the paving brick unit 400. A transparent plate is fixedly connected to the upper surface of the photosensitive lamps 401. Limiting blocks 103 are slidably fitted on the surfaces of multiple support pillars 102. The sides of the multiple limiting blocks 103 that are close to each other are respectively attached to the outer walls of the base block 402. The circuit system of the photosensitive lamps 401 includes a combined control unit of a photosensitive sensor and a microwave radar module, and the detection direction of the microwave radar module extends to both sides at an acute angle.

[0036] In this embodiment, the photosensitive lamps 401 embedded on both sides inside the paving brick unit 400 use LED light sources, the transparent plate is made of 3mm thick polycarbonate material, the surface is coated with a titanium dioxide-based self-cleaning coating, and the photosensitive sensor uses a cadmium sulfur compound photodiode with a short response time.

[0037] The microwave radar module operates at a frequency of 24GHz, has a wide-angle detection range, and an effective detection distance of 5m. The limiting blocks 103, which are slidably fitted onto the surfaces of multiple support pillars 102, are made of high-density polyethylene. Their inner diameter is fitted with the outer diameter of the support pillar 102 with a clearance. The axial positioning grooves are fitted with the protruding ridges on the outer wall of the base block 402. When the ambient temperature changes, the paving brick unit 400 uses the difference in thermal expansion coefficient between the aluminum alloy of the base block 402 and the galvanized steel pipe of the support pillar 102 to create a sliding compensation amount on the surface of the support pillar 102, thereby improving the flexibility of the paving brick unit 400.

[0038] Precise lighting control is achieved through the dual-modal sensing system of the photosensitive lamp 401. When the radar detects a moving target, the light strip automatically starts and stays on for 30 seconds before turning off. The self-cleaning function of the transparent plate reduces the frequency of manual maintenance, while the sliding compensation mechanism of the limit block 103 keeps the change in joint width of the paving brick unit 400 within a certain value under temperature cycling, ensuring structural durability and safety in use.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, a partition net 303 is fixedly connected to the top of the drain pipe 300. Cover plates 305 abut against both sides of the partition net 303. The cover plates 305 are attached to the surface of the drain pipe 300. A sleeve 302 is fitted on the surface of the drain pipe 300 and the cover plate 305. The other end of the sleeve 302 is fitted on the surface of the water guide pipe 301. A limit frame 304 is fixedly connected to the surface of the partition net 303. The limit frame 304 is located inside the drain pipe 300, and both sides of the limit frame 304 are attached to the inner wall of the drain pipe 300.

[0040] In this embodiment, a stainless steel mesh 303 is fixedly connected to the inlet end of the drain pipe 300. The mesh 303 is woven from stainless steel wire, allowing rainwater to permeate while effectively intercepting debris. Cover plates 305 abut against both sides of the mesh 303. The edges of the cover plates 305 are bonded to the outer wall of the drain pipe 300 with silicone sealant, forming a double-sealed structure. A sleeve 302 is fitted onto the connection between the drain pipe 300 and the water guide pipe 301. The joint of the sleeve 302 is hot-melt welded to ensure connection strength. The limiting bracket 304 is made of bent stainless steel round tube. The arc-shaped support structure is welded to the inner wall of the drain pipe 300 at both ends, which improves the axial positioning accuracy of the limit frame 304. The multi-stage filtration system is formed by the mesh 303 and the ceramic granule filter layer, which improves the solid suspended matter interception rate of the drainage system. The sealing structure of the cover plate 305 and the sleeve 302 can withstand water pressure without leakage. The arc-shaped structure of the limit frame 304 makes the flow velocity distribution in the drain pipe 300 uniform and reduces eddy current loss. Each component is designed with standardized modules to achieve quick installation and replacement. The cleaning cycle of the mesh 303 is extended and the maintenance cost is reduced.

[0041] Working principle: Rainwater rapidly infiltrates through the permeable concrete layer of the paving brick unit 400, and after entering the topsoil layer 500, it undergoes initial filtration through the graded filtration of sand, gravel, and improved soil, trapping suspended solids. The untrapped rainwater flows into the expanded clay aggregate filling module 200, where the porous structure of the lightweight expanded clay aggregate adsorbs impurities. It then flows through the guide channel 202 of the bottom gravel layer into the drainage pipe 300. The stainless steel mesh 303 at the inlet of the drainage pipe 300 provides secondary interception of debris. The sealing structure of the cover plate 305 and the sleeve 302 prevents leakage, and the arc-shaped support of the limiting frame 304 optimizes water flow distribution. Finally, the rainwater is discharged into the main drainage system through the water guide pipe 301, achieving multi-stage purification.

[0042] The paving brick unit 400 is connected to the base 101 via a tenon-and-mortise positioning boss. The cantilever structure on both sides transfers the load to the ceramsite filling module 200. The galvanized steel pipe support 102 on the top surface of the base 101 is bolted to the aluminum alloy base block 402. The polytetrafluoroethylene anti-friction pad at the bottom of the bottom support block 100 allows the paving brick to slide along the axis of the support 102 when the temperature changes. The aggregate gaps of the permeable concrete paving brick and the joint layer of the soil cover 500 form a continuous seepage channel. Combined with the water storage capacity of the ceramsite module, rainwater can quickly infiltrate and groundwater can be replenished. The photosensitive sensor and the microwave radar module form a dual-mode control unit. When the ambient light intensity decreases and the radar detects a moving target, the photosensitive lamp 401 automatically turns on and turns off after a 30-second delay. The titanium dioxide self-cleaning coating of the polycarbonate transparent plate decomposes dirt through photocatalytic reaction, reducing the frequency of manual cleaning. Through the standardized design of functional modules and the precise control of material parameters, the organic unity of structural stability, ecological benefits and intelligence is achieved, improving the comfort of personnel.

[0043] It should be noted that the photosensitive lamp 401, photosensitive sensor and microwave radar module mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the photosensitive lamp 401, photosensitive sensor and microwave radar module can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
