Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to municipal green roads with prefabricated permeable paving structures. Background Technology

[0002] With the acceleration of urbanization, traditional impermeable hardened pavements have been widely covered, severely disrupting the natural hydrological cycle. When it rains, these pavements cannot effectively infiltrate rainwater, causing surface runoff to accumulate rapidly. This not only puts enormous pressure on municipal drainage networks and easily leads to urban flooding, but also causes a large loss of precious water resources.

[0003] Referring to the patent document: Patent Publication No. CN218621639U, Patent Publication Date 2023-03-14, a prefabricated permeable pavement structure is provided. The prefabricated permeable pavement structure includes partition blocks. In the assembled state, the partition blocks are spaced apart along the road extension direction. The space formed by the intervals is filled from bottom to top with a number of steel slag permeable base blocks, a steel slag sand leveling layer, and a number of steel slag permeable pavement bricks. The prefabricated permeable pavement structure can be assembled into a specific pavement structure during use, thereby realizing combined assembly construction, high construction efficiency, and facilitating targeted local maintenance when local road sections are damaged.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Although existing permeable brick paving roads have a certain degree of permeability, they can still cause water accumulation on the road surface when the infiltration rate of the roadbed is lower than the rainfall intensity during heavy rainfall. In addition, the traditional permeable brick paving structure has poor overall integrity and is prone to loosening and subsidence under long-term loads, which not only affects driving comfort and safety but also increases the later maintenance costs.

[0005] Therefore, this utility model provides a municipal green road with a prefabricated permeable pavement structure. Utility Model Content

[0006] To address the problems of existing permeable brick roads being prone to water accumulation due to insufficient infiltration rate during heavy rainfall, and their poor structural integrity leading to loosening and subsidence under long-term loads, the purpose of this utility model is to provide municipal greening roads with prefabricated permeable paving structures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a municipal green road with a prefabricated permeable pavement structure, comprising a roadbed soil layer, wherein a permeable green road is provided on the upper part of the roadbed soil layer for rapid paving of the expressway and drainage of rainwater, the permeable green road comprising: The permeable main road includes a crushed stone cushion layer laid on the upper surface of the middle of the subgrade soil layer, a steel slag sand cushion layer laid on the upper surface of the crushed stone cushion layer, multiple spliced ​​blocks laid on the upper surface of the steel slag sand cushion layer with adjacent spliced ​​blocks arranged in an alternating pattern, multiple fixed blocks laid side by side on the upper surface of the middle of the steel slag sand cushion layer with the ends of the fixed blocks in contact with each other, and two sets of edge protection blocks laid on the upper surface of the steel slag sand cushion layer with the inner set of edge protection blocks in contact with the sides of the spliced ​​blocks located on both sides. The green auxiliary road is located in the middle of two sets of edge protection blocks and is used for planting vegetation on both sides of the road.

[0008] The greening auxiliary road includes gravel layers laid on the upper surface of both sides of the roadbed soil layer, and a planting base layer for planting is laid on the upper surface of both gravel layers.

[0009] The permeable main road also includes a water trough opened in the middle of multiple spliced ​​blocks, and a water storage trough opened in the middle of multiple fixed blocks, and the water storage trough and the water trough are interconnected.

[0010] One side of each of the multiple splicing blocks is integrally formed with a positioning block, and the other side of each of the multiple splicing blocks is provided with a positioning groove that cooperates with the positioning block.

[0011] Each of the fixed blocks has two symmetrically distributed splicing blocks integrally formed on both sides. Splicing grooves are opened at the middle of both ends of the multiple splicing blocks. The multiple splicing blocks are slidably locked in the splicing grooves. The multiple splicing grooves are interconnected with the water channel.

[0012] The permeable main road also includes a vertical drainage channel in the middle of the edge protection block, and a horizontal drainage channel in the middle of one of the edge protection blocks. The horizontal drainage channels intersect and are connected to each other. The horizontal drainage channels are connected to the water storage tank. An installation block is integrally formed in the middle of one end of multiple edge protection blocks, and an installation groove is formed at the other end of multiple edge protection blocks to cooperate with the installation block.

[0013] Beneficial effects This utility model provides a municipal green road with a prefabricated permeable pavement structure. Compared with the prior art, it has the following advantages: 1. The permeable main road of this application is formed by staggered insertion of permeable precast bricks (interlocking blocks). The water flow channel in the middle of the block is interconnected with the water storage channel in the fixed block to form an efficient water collection system. When it rains, rainwater can quickly seep through the brick body. In case of heavy rainfall, the water accumulated in the base layer can flow back into the water flow channel and be concentrated and guided to the water storage channel. Then, it is discharged into the drainage system through the horizontal and vertical drainage channels, which greatly improves the drainage capacity of the road surface and effectively prevents waterlogging. Moreover, by inserting the fixed block vertically from the top and locking it with the blocks on both sides, a strong lateral restraint is formed, which connects the scattered blocks into a whole, significantly enhancing the structural stability and displacement resistance of the road surface and extending its service life.

[0014] 2. In this application, the green auxiliary road is located on both sides of the main road. The gravel layer at the bottom and the planting base layer at the top together form the growth space for plants. This structure can not only effectively retain water for plants to absorb, but the gravel layer inside also serves as an additional permeable and water-storing layer, which can receive and temporarily store some of the excess rainwater that seeps from the main road, thus delaying the formation of runoff.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a municipal green road with a prefabricated permeable pavement structure, including a roadbed soil layer 1, which is made of compacted plain soil with a compaction degree of not less than 95%. A permeable green road 2 is provided on top of the roadbed soil layer 1 for rapid paving of the expressway and drainage of rainwater. The permeable green road 2 includes: The permeable main road 21 includes a crushed stone cushion layer 211 laid on the upper surface of the middle section of the subgrade soil layer 1. The porosity of the crushed stone cushion layer 211 is approximately 20%. A steel slag sand cushion layer 212 is laid on the upper surface of the crushed stone cushion layer 211. Multiple interlocking blocks 213 are laid on the upper surface of the steel slag sand cushion layer 212, with adjacent interlocking blocks 213 arranged in an alternating pattern. The interlocking blocks 213 are permeable precast bricks. To ensure the overall stability of the structure, the interlocking blocks 213 are laid in a staggered manner. Multiple fixed blocks 215 are laid side-by-side on the upper surface of the middle section of the steel slag sand cushion layer 212. Each fixed block 215 on the permeable main road 21... A set of blocks is laid side by side every 3 to 5 meters, which is connected with the splicing blocks 213 to further strengthen and limit the structure. The fixed blocks 215 and the ends of multiple splicing blocks 213 are in contact with each other. Two sets of edge protection blocks 218 are laid on the upper surface of the steel slag sand cushion layer 212. The inner set of edge protection blocks 218 is in contact with the sides of the splicing blocks 213 on both sides. The inner set of edge protection blocks 218 is used to protect the sides of the splicing blocks 213 laid on the permeable main road 21 to prevent the splicing blocks 213 from becoming loose after splicing. This can isolate the permeable main road 21 from the green auxiliary road 22. Green auxiliary road 22 is set in the middle of two sets of edge protection blocks 218 and is used for planting vegetation on both sides of the road.

[0023] The green auxiliary road 22 includes gravel layers 221 laid on the upper surface of both sides of the roadbed soil layer 1. The upper surface of both gravel layers 221 is covered with a planting base layer 222 for planting. The gravel layer 221 inside is 120mm thick and has a particle size of 15mm. The planting base layer 222 on top is 350mm thick.

[0024] The permeable main road 21 also includes a water channel 214 opened in the middle of multiple spliced ​​blocks 213, and a water storage tank 216 opened in the middle of multiple fixed blocks 215. The water storage tank 216 and the water channel 214 are interconnected. The water channel 214 can guide the flow of water. When it rains, rainwater seeps downward through the permeability of the spliced ​​blocks 213, and some of the water can flow into the water channel 214 and flow into the water storage tank 216. At the same time, when the rainfall exceeds the seepage rate of the underground base layer, the water rises and will cause the rainwater to enter the water channel 214. Due to the interconnected guiding effect of the water channel 214, it flows into the water storage tank 216 opened in the middle of the fixed blocks 215 for centralized collection.

[0025] One side of the multiple splicing blocks 213 has an integrally formed positioning block 2131, and the other side of the multiple splicing blocks 213 is provided with a positioning groove that cooperates with the positioning block 2131. During splicing, the positioning block 2131 is slidably inserted into the positioning groove to realize the splicing and laying of two splicing blocks 213. This allows the vertical positioning of the two splicing blocks 213 to be limited. After splicing, they cannot be pulled out from the middle. During laying, the laying space of the fixing block 215 is first left. After splicing the splicing blocks 213 on both sides of the fixing block 215, the middle of the splicing blocks 213 on both sides of the fixing block 215 is inserted downward to complete the splicing with the splicing blocks 213 on both sides.

[0026] Each of the fixed blocks 215 has two symmetrically distributed splicing blocks 2171 integrally formed on both sides. Each of the splicing blocks 213 has a splicing groove 217 at the middle of both ends. The splicing blocks 2171 are slidably locked in the splicing grooves 217. The splicing grooves 217 are interconnected with the water channel 214. The splicing blocks 2171 have a two-thirds cylindrical structure, so that after being inserted into the splicing grooves 217, they can only slide up and down and cannot be pulled out horizontally. Thus, after the fixed blocks 215 are inserted downward from the middle of the splicing blocks 213 on both sides, the horizontal direction of the splicing blocks 213 can be limited, making the structure more stable. At the same time, the splicing grooves 217 that are not spliced ​​with the splicing blocks 2171 can be used for rapid infiltration of rainwater during rainfall.

[0027] The permeable main road 21 also includes vertical drainage channels 219 formed in the middle of the edge protection blocks 218. A transverse drainage channel 2191 is formed in the middle of one of the edge protection blocks 218, and these transverse drainage channels 2191 intersect and are interconnected. The transverse drainage channels 2191 are interconnected with the water storage tank 216. When rainwater flows into the water storage tank 216, it is guided into the transverse drainage channels 2191, and then into the vertical drainage channels 219 that intersect and are interconnected with them. The water is guided by the vertical drainage channel 219 to the external pre-installed drainage system. One end of the multiple edge protection blocks 218 has an integrally formed installation block 2181, and the other end of the multiple edge protection blocks 218 has an installation groove that cooperates with the installation block 2181. The installation block 2181 and the installation groove make the multiple edge protection blocks 218 more integral and unable to move laterally, thus making them better protect the permeable main road 21 and the green auxiliary road 22.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During paving, the subgrade soil layer 1 is first compacted to a density of over 95% to form a solid foundation. A high-porosity crushed stone cushion layer 211 is laid on the upper surface of the middle section of the subgrade soil layer 1, and gravel layers 221 are laid on both sides. Then, a steel slag sand cushion layer 212 is laid on the crushed stone cushion layer 211, together forming a permeable, water-retaining, and stable base course. Permeable precast bricks with positioning blocks 2131 and positioning grooves are interlocked on the steel slag sand cushion layer 212, arranged in a staggered pattern. Through horizontal sliding insertion, a stable main road surface is quickly formed. Every 3-5 meters, a gap is left. The ends of the interlocking blocks 213 on both sides are assembled first, and then fixed blocks 215 with interlocking blocks 2171 are vertically inserted from above into the reserved gaps. The splicing block 2171 will be inserted into the splicing groove 217 of the adjacent splicing block 213 to form a horizontal lock, thereby "tightening" the entire row of blocks. On both sides of the permeable main road 21, the edge protection blocks 218 are installed by interlocking the installation blocks 2181 and the installation groove. On the one hand, they serve as curb stones to protect the edge of the main road and prevent the splicing blocks 213 from loosening laterally. On the other hand, they can clearly separate the permeable main road 21 from the green auxiliary road 22. The planting base layer 222 is laid on the gravel layer 221 on both sides of the subgrade soil layer 1, which can be used for planting plants. After rainwater falls onto the surface of the permeable main road 21, most of the rainwater directly infiltrates downwards due to the permeability of the spliced ​​blocks 213. It passes through the steel slag sand cushion layer 212 and the crushed stone cushion layer 211 in sequence, and finally seeps into the subgrade soil layer 1, completing natural infiltration. When the rainfall intensity exceeds the infiltration rate of the base layer, causing temporary water accumulation in the base layer, the water level rises and overflows into the interconnected drainage channels 214. All rainwater flowing into the drainage channels 214 is guided by the channels and flows into the water storage tanks 216 in the fixed blocks 215 set at intervals. The rainwater collected in the water storage tanks 216 is discharged through the transverse drainage channels 2191 connected to them. The rainwater flows in the transverse drainage channels 2191 and flows into the vertical drainage channels 219 that intersect with it. Finally, the rainwater is guided by the vertical drainage channels 219 and is transported to the external municipal drainage network or designated drainage system to achieve active and forced drainage and completely avoid waterlogging.
