Background Art

[0002] In the ever-accelerating urbanization process, urban stormwater problems have gradually become a new challenge that people face. Irrational urban development and construction have brought about urban stormwater problems. Irrational land development has increased the impervious area in the city, which has directly affected rainwater infiltration, causing rainwater to quickly flow away from the surface, making it impossible to achieve the purpose of rainwater replenishing groundwater. Ultimately, cities will experience waterlogging during rainy seasons, causing inconvenience to citizens' lives. Roads play an irreplaceable role in urban construction. With the expansion of cities, the area of ​​roads continues to increase, making road surface runoff pollution the main source of surface runoff pollution, and the green landscaping of urban roads has also been continuously reduced. Moreover, the cost of green landscaping irrigation remains high. Therefore, it is necessary to improve the structure of the road green belt foundation in the existing technology. Summary of the Invention

[0003] The present invention is aimed at the above problems and provides a road green belt infrastructure structure that can intercept, reduce emissions and retain rainwater. The retained rainwater can meet the needs of plant growth in road green spaces, reduce green space irrigation costs, is easy to install and lay, shortens road construction periods, effectively reduces construction costs, and is highly practical.

[0004] The technical solution adopted by the present invention is: the road green belt infrastructure structure includes a green space bottom foundation, which is characterized in that: a permeable green space module is arranged on the upper side of the green space bottom foundation, one side of the upper part of the permeable green space module is a straight structure, and the other side of the upper part of the permeable green space module is provided with a green space water collection slope trough, and green space vegetation is arranged on the upper side of the permeable green space module, and several groups of drainage curbs arranged along the extension direction of the road are respectively provided on both sides of the permeable green space module; a pedestrian walkway is also provided above the green space water collection slope trough, and a sidewalk support structure is provided below the pedestrian walkway.

[0005] Between the straight structure of the water-seepage green space module and the sloped water collection trough, a water collection overflow trough is installed along the extension of the green belt. The bottom of the water collection overflow trough is connected to the water collection pipe installed on the side of the water-seepage green space module via an overflow pipeline. When the accumulated water in the sloped water collection trough of the green space reaches the overflow level, the overflow flows into the water collection overflow trough, then flows through the overflow pipeline to the water collection pipe on the side of the water-seepage green space module, and finally into the municipal pipeline.

[0006] The water collection overflow trough adopts a structure consisting of multiple segmented troughs arranged in a continuous pattern. Each segmented trough is provided with an overflow trough cover plate on its upper side, and an overflow inlet is provided on the overflow trough cover plate. This continuous segmented structure facilitates the processing and layout of the water collection overflow trough, and allows the overflow from the green space water collection slope trough to flow into each segmented trough through the overflow inlet on the overflow trough cover plate.

[0007] The green space water collection slope trough is connected to the overflow trough cover of the water collection overflow trough through the diversion slope surface, so that rainwater on one side of the straight structure of the seepage green space module flows through the overflow trough cover and the diversion slope surface into the green space water collection slope trough for temporary storage.

[0008] Water collection and diversion baffles are also installed above the overflow inlet of the overflow trough cover. The water collection and diversion baffles installed above the overflow inlet of the segmented trough body are used to guide rainwater on the straight structure side of the seepage green space module to flow into the green space water collection slope trough, preventing accumulated rainwater from flowing directly into the overflow inlet.

[0009] The sidewalk support structure consists of multiple, sequentially arranged, split structures. Each split structure includes a longitudinal support frame and a transverse support frame that contact the sidewalk, with the transverse support frames arranged crosswise with the longitudinal support frames. Vertical poles are located below the transverse support frames, with their upper ends connected to the middle of the transverse support frames and their lower ends connected to bottom fixing rods. The bottom fixing rods are fixedly connected to the green space water collection slope trough. The three-dimensional support structure formed by the vertical poles, longitudinal support frames, and transverse support frames provides stable support for the sidewalk above the green space water collection slope trough, allowing the sidewalk and green space water collection slope trough to be arranged in an upper and lower layer, fully utilizing the space.

[0010] A transverse frame engaging groove is provided in the middle of the longitudinal support frame, and longitudinal frame connecting portions are provided at the two longitudinally extending ends of the longitudinal support frame. One end of the longitudinal support frame is connected to a supporting connecting frame provided on the upper portion of the water collection overflow trough via the longitudinal frame connecting portion, and a drainage port is further provided in the middle of the supporting connecting frame. The longitudinal support frame is connected to the transverse support frame via the transverse frame engaging groove, and the positions of the longitudinal support frame and the transverse support frame are fixed by support frame plug-in columns provided in the plug-in column holes. The longitudinal frame connecting portion at one end of the longitudinal support frame is fixedly connected to the supporting connecting frame on the upper portion of the water collection overflow trough. The supporting connecting frame connected to the longitudinal support frame is then used to provide auxiliary support for the end of the pedestrian walkway, and the drainage port provided on the supporting connecting frame facilitates the flow of rainwater into the green space water collection slope trough.

[0011] A longitudinal frame engaging groove is provided in the middle of the transverse support frame. A transverse frame connecting groove and a transverse frame connecting protrusion are provided at each of the transverse support frame's two transverse extending ends. Transverse frame connecting protrusions and the transverse frame connecting groove are correspondingly provided with transverse frame connecting fixing holes. A continuous arrangement of transverse support frames is formed by connecting two adjacent sets of transverse support frame end portions and the cooperating transverse frame connecting grooves and transverse frame connecting protrusions. Each set of transverse support frames is secured using bolts disposed in the transverse frame connecting fixing holes.

[0012] The upper end of the vertical pole is provided with a transverse frame plug-in top column, and the lower end of the vertical pole is provided with a fixed rod plug-in bottom column. The upper end of the vertical pole is connected to the transverse support frame by plugging the transverse frame into the top column, and the lower end of the vertical pole is fixedly connected to the bottom fixed rod by plugging the fixed rod into the bottom column.

[0013] The bottom fixing rod is a segmented structure, with each segment having a fixing rod mating slot at each end for interconnection. The fixing rod mating slots also contain bottom column insertion slots for mating with the fixing rod inserting bottom column. The fixing rod mating slots at the ends of each segment are used to assemble the various segments of the bottom fixing rod into a single piece, and the fixing rod inserting bottom column at the lower end of the vertical rod is inserted into the bottom column insertion slot within the fixing rod mating slots.

[0014] The beneficial effects of the present invention are as follows: since the present invention adopts a green space bottom foundation, a seepage green space module is provided on the upper side of the green space bottom foundation, one side of the upper part of the seepage green space module is a straight structure, and a green space water collection slope trough is provided on the other side of the upper part of the seepage green space module, green space vegetation is arranged on the upper side of the seepage green space module, and several groups of drainage curbs arranged along the extension direction of the road are provided on both sides of the seepage green space module; a pedestrian walkway is provided above the green space water collection slope trough, and a sidewalk support structure is provided below the pedestrian walkway, so its design is reasonable and its structure is compact, which can effectively solve the rainwater problem of urban roads, and rainwater can be intercepted, reduced and retained by adopting systematic green infrastructure; this new stormwater management system structure can reduce construction costs, and at the same time, the retained rainwater can meet the needs of plant growth in road green spaces, and also reduce the cost of green space irrigation, which is of economic significance; it is easy to install and lay, the road construction period is short, and it is highly practical.

[0021] according to Figures 1 to 5 The specific structure of the present invention is described in detail. The road green belt infrastructure includes a green space bottom foundation 1, and a water-seepage green space module 2 is provided on the upper side of the green space bottom foundation 1. The water-seepage green space module 2 is provided with water seepage holes inside to accelerate the infiltration of rainwater; and the folded edge positions of the module edges are respectively provided with perforated weather-resistant plates to prevent soil and water loss. At the same time, the upper part of the water-seepage green space module 2, on the side close to the middle road surface, is a straight structure, and the upper part of the water-seepage green space module 2, on the other side away from the middle road surface, is provided with a green space water collection slope trough 3. Between the straight structure of the water-seepage green space module 2 and the green space water collection slope trough 3, there is also a water collection overflow trough 4 arranged along the extension direction of the green belt. The bottom of the water collection overflow trough 4 is connected to the water collection pipe 5 provided on the side of the water-seepage green space module 2 through the overflow pipeline 11 (such as Figure 1 and Figure 2 As shown). When the accumulated water in the green space water collection slope trough 3 reaches the overflow level, the overflow flows into the water collection overflow trough 4, and then flows through the overflow pipeline 11 to the water collection pipe 5 on the side of the seepage green space module 2, and finally flows into the municipal pipeline.

[0022] The water collection overflow trough 4 adopts a structural form consisting of a plurality of segmented trough bodies 13 arranged in series. An overflow trough upper cover plate 14 is provided on the upper side of each segmented trough body 13, and an overflow inlet 15 is provided on the overflow trough upper cover plate 14. In addition, the green space water collection slope trough 3 is connected to the overflow trough upper cover plate 14 of the water collection overflow trough 4 through the diversion slope surface 12. As a result, rainwater on one side of the straight structure of the seepage green space module 2 flows through the overflow trough upper cover plate 14 and the diversion slope surface 12 into the green space water collection slope trough 3 for temporary storage; and the structural form of segmented continuous arrangement facilitates the processing and layout of the water collection overflow trough 4, and allows the overflow in the green space water collection slope trough 3 to flow from the overflow inlet 15 on the overflow trough upper cover plate 14 into each segmented trough body 13. In addition, water collecting and diverting baffles 7 are respectively provided above the overflow inlet 15 of the overflow trough upper cover plate 14; the water collecting and diverting baffles 7 provided above the overflow inlet 15 of the segmented trough body 13 are used to guide the flow of rainwater on one side of the straight structure of the seepage green space module 2 to the green space water collecting slope trough 3, thereby preventing the accumulated rainwater from directly flowing into the overflow inlet 15.

[0023] At the same time, green vegetation 8 is arranged on the upper side of the seepage green space module 2, and several groups of drainage curbs 6 are arranged along the extension direction of the road on both sides of the seepage green space module 2. A pedestrian walkway 9 is also arranged above the green space water collection slope trough 3, and a sidewalk support structure 10 (such as Figure 1 As shown). The sidewalk support structure 10 is composed of a plurality of continuously arranged split structures, each of which includes a longitudinal support frame 18 and a transverse support frame 19 in contact with the sidewalk 9, and the transverse support frame 19 is arranged crosswise with the longitudinal support frame 18. A vertical upright 20 is provided below the transverse support frame 19, the upper end of the vertical upright 20 is connected to the middle of the transverse support frame 19, and the lower end of the vertical upright 20 is connected to the bottom fixed rod 21; the bottom fixed rod 21 is fixedly connected to the green space water collection slope trough 3 (as shown). Figure 3 As shown). Thus, the vertical support structure composed of the vertical poles 20 and the longitudinal support frames 18 and the transverse support frames 19 provides a stable support for the walkway 9 above the green space water collection slope trough 3, so that the walkway 9 and the green space water collection slope trough 3 form an upper and lower layer arrangement, making full use of the space.

[0024] A transverse frame engaging groove 22 is provided in the middle of the longitudinal support frame 18, and longitudinal frame connecting portions 23 are provided at each of the longitudinally extending ends of the longitudinal support frame 18. One end of the longitudinal support frame 18 is connected to the support connecting frame 16 provided above the water collection overflow trough 4 via the longitudinal frame connecting portion 23. A drainage port 17 is also provided in the middle of the support connecting frame 16. The longitudinal support frame 18 is then connected to the transverse support frame 19 via the transverse frame engaging groove 22, and the positions of the longitudinal support frame 18 and the transverse support frame 19 are fixed by support frame plug-in posts 32 provided in plug-in post holes 33. The longitudinal frame connecting portion 23 at one end of the longitudinal support frame 18 is fixedly connected to the support connecting frame 16 above the water collection overflow trough 4, thereby utilizing the support connecting frame 16 connected to the longitudinal support frame 18 to provide auxiliary support for the end of the walkway 9. The drainage port 17 provided on the support connecting frame 16 facilitates the flow of rainwater into the green space water collection slope trough 3.

[0025] A longitudinal frame snap-in groove 24 is provided in the middle of the transverse support frame 19, and a transverse frame connecting groove 25 and a transverse frame connecting protrusion 27 are respectively provided at the two transverse extending ends of the transverse support frame 19, and transverse frame connecting protrusions 27 and the transverse frame connecting grooves 25 are correspondingly provided with transverse frame connecting fixing holes 26; by connecting the end joints of two adjacent groups of transverse support frames 19, the mutually cooperating transverse frame connecting grooves 25 and the transverse frame connecting protrusions 27, a continuously arranged transverse support frame 19 is formed, and each group of transverse support frames 19 is fixed by bolts provided in the transverse frame connecting fixing holes 26.

[0026] The upper ends of the vertical uprights 20 of the sidewalk support structure 10 are equipped with transverse frame plug-in top posts 28, while the lower ends of the vertical uprights 20 are equipped with fixed rod plug-in bottom posts 29. Furthermore, the bottom fixed rod 21 is assembled in sections, with each section having a fixed rod mating slot 30 at each end for interconnection. Within the fixed rod mating slots 30 are bottom column insertion slots 31 for mating with the fixed rod plug-in bottom posts 29. Thus, the fixed rod mating slots 30 at the ends of each section are used to assemble the various sections of the bottom fixed rod 21 into a single piece. The transverse frame plug-in top posts 28 connect the upper ends of the vertical uprights 20 to the transverse support frame 19, and the fixed rod plug-in bottom posts 29 at the lower ends of the vertical uprights 20 are inserted into the bottom column insertion slots 31 within the fixed rod mating slots 30.

[0027] When the road green belt infrastructure is used, first, a green space bottom foundation 1 is laid out on the bottom layer, and a permeable green space module 2 is set up on the upper side of the green space bottom foundation 1. At the same time, the straight structure on the upper part of the permeable green space module 2 is arranged on the side close to the central road surface, while the green space water collection slope trough 3 on the upper part of the permeable green space module 2 is arranged on the other side away from the central road surface. Then, between the straight structure of the permeable green space module 2 and the green space water collection slope trough 3, a water collection overflow trough 4 composed of multiple segmented troughs 13 is laid out along the extension direction of the green belt, and the water collection overflow trough 4 is connected to the water collection pipe 5 set on the side of the permeable green space module 2 through the overflow pipeline 11. The water collection pipe 5 is then connected to the municipal pipeline under the central road surface. Afterwards, a layer of green vegetation 8 is laid out on the upper side of the permeable green space module 2, and drainage curbs 6 are arranged on both sides of the permeable green space module 2 along the extension direction of the road. Subsequently, a pedestrian walkway 9 is set above the green space water collection slope trough 3, and a sidewalk support structure 10 composed of a bottom fixing rod 21, a vertical pole 20, a longitudinal support frame 18 and a transverse support frame 19 is set below the pedestrian walkway 9.

[0028] During use, excess rainwater falling on the green vegetation 8 beside the sidewalk 9 is guided by the water collection guide baffle 7 above the overflow inlet 15 of the water collection overflow trough 4 and flows into the green water collection slope trough 3, thereby achieving temporary storage. Moreover, when the accumulated water in the green water collection slope trough 3 reaches the overflow level, the overflow will flow into the water collection overflow trough 4 through the overflow inlet 15, then flow through the overflow pipeline 11 to the water collection pipe 5 on the side of the seepage green space module 2, and finally merge into the municipal pipeline. As a result, the rainwater retained in the green water collection slope trough 3 can meet the needs of plant growth in the road green space, reducing the cost of green space irrigation.
