Description

Technical Field

[0001] This utility model relates to the field of curbstone technology, and in particular to a curbstone structure based on the concept of sponge city. Background Technology

[0002] The core of the sponge city concept is to achieve the natural accumulation, infiltration, and purification of urban rainwater through ecological design, constructing a "resilient" water cycle system to address challenges such as urban flooding and water shortages. Its core strategy can be summarized as the six-word principle of "infiltration, retention, storage, purification, utilization, and drainage." Curbstones are marker stones placed between the road surface and other structures; they are typically required between the median strip and the road surface, and between sidewalks and the road surface in urban roads.

[0003] Traditional curbstone designs are impermeable, leading to increased runoff. By incorporating sponge city concepts into curbstones, multiple benefits can be achieved, primarily through optimized stormwater management, enhanced ecological functions, and improved infrastructure sustainability. Therefore, there is an urgent need for a curbstone design based on the sponge city concept. Utility Model Content

[0004] The purpose of this utility model is to provide a curbstone structure based on the concept of sponge city, which optimizes rainwater management, enhances ecological functions, and improves the sustainability of infrastructure to achieve multiple benefits.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a curbstone structure based on the concept of sponge city, comprising multiple curbstone bodies arranged side by side, multiple permeable concrete bases arranged side by side on the lower surface and back side of the multiple curbstone bodies, the multiple curbstone bodies being bonded to the multiple permeable concrete bases after being solidified by cement mortar, the permeable concrete bases being provided with drainage holes extending horizontally through both ends, and a first joint for connecting between the drainage holes of adjacent permeable concrete bases, or a second joint for connecting and realizing the discharge of rainwater to the manhole.

[0006] By adopting the above technical solutions, when rainwater infiltrates near the curbstone, some of the rainwater can infiltrate downwards to the permeable concrete base, accelerating rainwater infiltration, reducing surface runoff erosion, and lowering the risk of urban flooding, thus realizing the "infiltration" principle of the sponge city concept. Some rainwater flows along the drainage holes and the first joint of the concrete base, and is discharged into the manhole from the second joint used for connection and drainage, thus realizing the "drainage" principle of the sponge city concept. Ultimately, the sponge city concept optimizes rainwater management, enhances ecological functions, and improves the sustainability of infrastructure, achieving multiple benefits.

[0007] A further feature of this invention is that the orthographic projection range of the curbstone body does not cover the drainage hole.

[0008] By adopting the above technical solution, since the strength of the permeable concrete base is relatively low, the design of not covering the drainage holes by the orthogonal projection range of the curbstone body can prevent the permeable concrete base from being crushed.

[0009] A further feature of this invention is that the curbstone body has a weight-reducing hole that extends horizontally through both ends in the middle.

[0010] By setting up weight-reducing holes, the weight of the curbstone itself is reduced, further preventing the permeable concrete base from being crushed.

[0011] A further feature of this invention is that: the permeable concrete base has first mounting holes at both ends that communicate with drainage holes; the lower surface of the permeable concrete base has a first opening groove that communicates with the first mounting holes; the two ends of the first connector are respectively inserted into the two first mounting holes; the two ends of the second connector are respectively inserted into the two first mounting holes; and the bottom of the second connector has a first drainage pipe portion that extends out of the first opening groove.

[0012] By adopting the above technical solution, the permeable concrete base is provided with first installation holes at both ends that connect to drainage holes. The two ends of the first connector are respectively inserted into the two first installation holes, thereby connecting the drainage holes of adjacent concrete bases. At the same time, the two ends of the second connector are respectively inserted into the two first installation holes. The bottom of the second connector is provided with a first drainage pipe that extends out of the first opening groove, thereby connecting the drainage holes of adjacent concrete bases and discharging rainwater to the manhole.

[0013] A further feature of this invention is that: three drainage holes are provided, one of which is located below the curbstone body, the orthographic projection of the curbstone body does not cover the other two drainage holes, the center line connecting the two drainage holes forms an obtuse triangle, a reinforcing pipe is provided inside the drainage hole, and at least two-thirds of the periphery of the reinforcing pipe is provided with seepage holes, while the remaining portion of the reinforcing pipe without seepage holes is located at the bottom.

[0014] By adopting the above technical solution, the three drainage holes can improve the drainage effect. Since the opening of multiple drainage holes has a significant impact on the strength of the permeable concrete base, the structural strength of the permeable concrete base is improved by setting up reinforcing pipes. At the same time, in the design of the reinforcing pipes, at least two-thirds of the periphery of the reinforcing pipes are provided with seepage holes, and the remaining part of the reinforcing pipes without seepage holes is located at the bottom. The part with seepage holes improves the seepage effect, and the part without seepage holes improves the drainage effect.

[0015] A further feature of this invention is that: the permeable concrete base has two second mounting holes at both ends that connect to three drainage holes; the lower surface of the permeable concrete base has a second opening groove that communicates with the second mounting holes; the main body of the first connector is placed between the second mounting holes of the two permeable concrete bases; the first connector has multiple first connecting pipe sections that are inserted into the drainage holes to connect to the reinforcing pipe; the main body of the second connector is placed between the second mounting holes of the two permeable concrete bases; the second connector has multiple second connecting pipe sections that are inserted into the drainage holes to connect to the reinforcing pipe; and the bottom of the second connector has a second drainage pipe section that extends out of the second opening groove.

[0016] By adopting the above technical solution, the main body of the first joint is placed between the second mounting holes of the two permeable concrete bases. The first joint is provided with a plurality of first connecting pipe sections that are inserted into the drainage holes to connect the reinforcing pipes, thereby connecting the reinforcing pipes in the drainage holes of the adjacent concrete bases. The main body of the second joint is placed between the second mounting holes of the two permeable concrete bases. The second joint is provided with a plurality of second connecting pipe sections that are inserted into the drainage holes to connect the reinforcing pipes. The bottom of the second joint is provided with a second drainage pipe section that extends out of the second opening groove, thereby connecting the reinforcing pipes in the drainage holes of the adjacent concrete bases and discharging rainwater to the manhole.

[0017] The present invention is further configured such that: the first connector includes a first main body portion having a plurality of first connecting pipe portions and a first insertion pipe portion at the bottom, and a sealing end cap disposed on a second insertion pipe portion; the second connector includes a second main body portion having a plurality of second connecting pipe portions and a second insertion pipe portion at the bottom, and a second drain pipe portion inserted into the insertion pipe portion; the first main body portion and the second main body portion have the same structure.

[0018] By adopting the above technical solution, the first main body and the second main body are designed to have the same structure, so that they can be processed using the same set of molds. At the same time, the sealing end cap seals the first insertion pipe, and the second drain pipe is inserted into the second insertion pipe to achieve installation. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: A curbstone structure based on the concept of sponge city, such as Figure 1 and Figure 2 As shown, it includes multiple curbstone bodies 1 arranged side by side, and multiple permeable concrete bases 2 arranged side by side on the lower surface and back side of the multiple curbstone bodies 1. The multiple curbstone bodies 1 are bonded to the multiple permeable concrete bases 2 after the cement mortar has solidified. The permeable concrete bases 2 are provided with drainage holes 2-1 that extend horizontally through both ends. A first joint 3 for connection or a second joint 4 for connection and to discharge rainwater to the manhole is provided between the drainage holes 2-1 of adjacent permeable concrete bases 2.

[0027] like Figures 1 to 3 As shown, the orthographic projection of the curbstone body 1 does not cover the drainage hole 2-1. A weight-reducing hole 1-1 is provided in the middle of the curbstone body 1, extending horizontally through both ends. The permeable concrete base 2 has first mounting holes 2-2 at both ends, connecting to the drainage hole 2-1. The lower surface of the permeable concrete base 2 has a first opening groove 2-3 communicating with the first mounting holes 2-2. The two ends of the first connector 3 are respectively inserted into the two first mounting holes 2-2. The two ends of the second connector 4 are respectively used to insert into the two first mounting holes 2-2. The bottom of the second connector 4 has a first drainage pipe section 4-1 extending out of the first opening groove 2-3.

[0028] Implementation Results: When rainwater infiltrates near the curbstone body 1, some rainwater can infiltrate downwards to the permeable concrete base 2, accelerating rainwater infiltration, reducing surface runoff erosion, and lowering the risk of urban flooding, thus realizing the "infiltration" principle of the sponge city concept; some rainwater flows along the drainage holes 2-1 and the first joint 3 of the concrete base, and is discharged into the manhole from the second joint 4 used for connection and drainage, thus realizing the "drainage" principle of the sponge city concept; ultimately, the sponge city concept optimizes rainwater management, enhances ecological functions, and improves the sustainability of infrastructure, achieving multiple benefits.

[0029] Because the permeable concrete base 2 has relatively low strength, the design ensures that the drainage hole 2-1 is not covered by the orthographic projection of the curbstone body 1, thus preventing the permeable concrete base 2 from being crushed. The weight-reducing holes 1-1 further reduce the weight of the curbstone body 1, further preventing the permeable concrete base 2 from being crushed. Both ends of the permeable concrete base 2 are provided with first mounting holes 2-2 connecting to the drainage holes 2-1. The two ends of the first connector 3 are respectively inserted into the two first mounting holes 2-2, thereby connecting the drainage holes 2-1 of adjacent concrete bases. Simultaneously, the two ends of the second connector 4 are respectively inserted into the two first mounting holes 2-2. The bottom of the second connector 4 is provided with a first drainage pipe part 4-1 extending through the first opening groove 2-3, thereby connecting the drainage holes 2-1 of adjacent concrete bases and allowing rainwater to be discharged into the manhole.

[0030] Example 2: A curbstone structure based on the concept of sponge cities, such as Figure 4 and Figure 5 As shown, it includes multiple curbstone bodies 1 arranged side by side, and multiple permeable concrete bases 2 arranged side by side on the lower surface and back side of the multiple curbstone bodies 1. The multiple curbstone bodies 1 are bonded to the multiple permeable concrete bases 2 after the cement mortar has solidified. The permeable concrete bases 2 are provided with drainage holes 2-1 that extend horizontally through both ends. A first joint 3 for connection or a second joint 4 for connection and to discharge rainwater to the manhole is provided between the drainage holes 2-1 of adjacent permeable concrete bases 2.

[0031] like Figure 4 and Figure 5 As shown, a weight-reducing hole 1-1 is provided in the middle of the curbstone body 1, extending horizontally through both ends. There are three drainage holes 2-1, one of which is located below the curbstone body 1. The orthographic projection of the curbstone body 1 does not cover the other two drainage holes 2-1. The center line connecting the two drainage holes 2-1 forms an obtuse triangle. A reinforcing pipe 5 is installed inside the drainage hole 2-1. At least two-thirds of the periphery of the reinforcing pipe 5 is provided with seepage holes 5-1, and the remaining part of the reinforcing pipe 5 without seepage holes 5-1 is located at the bottom.

[0032] like Figure 4 and Figure 5 As shown, the permeable concrete base 2 has two second mounting holes 2-4 at both ends that connect to three drainage holes 2-1. The lower surface of the permeable concrete base 2 has a second opening groove 2-5 that communicates with the second mounting holes 2-4. The main body of the first connector 3 is placed between the two second mounting holes 2-4 of the permeable concrete base 2. The first connector 3 has multiple first connecting pipe parts 3-11 that are inserted into the drainage holes 2-1 to connect to the reinforcing pipe 5. The main body of the second connector 4 is placed between the two second mounting holes 2-4 of the permeable concrete base 2. The second connector 4 has multiple second connecting pipe parts 4-21 that are inserted into the drainage holes 2-1 to connect to the reinforcing pipe 5. The bottom of the second connector 4 has a second drainage pipe part 4-3 that extends out of the second opening groove 2-5.

[0033] Meanwhile, the first connector 3 includes a first main body part 3-1 having multiple first connecting pipe parts 3-11 and a first insertion pipe part 3-12 at the bottom, and a sealing end cap 3-2 disposed on the second insertion pipe part 3-12. The second connector 4 includes a second main body part 4-2 having multiple second connecting pipe parts 4-21 and a second insertion pipe part 4-22 at the bottom, and a second drain pipe part 4-3 inserted into the insertion pipe part. The first main body part 3-1 and the second main body part 4-2 have the same structure.

[0034] Implementation Results: Firstly, the three drainage holes 2-1 improve the drainage effect. However, since the opening of multiple drainage holes 2-1 has a significant impact on the strength of the permeable concrete base 2, the structural strength of the permeable concrete base 2 is improved by setting up reinforcing pipes 5. At the same time, in the design of reinforcing pipes 5, at least two-thirds of the periphery of reinforcing pipes 5 are provided with seepage holes 5-1, and the remaining part of reinforcing pipes 5 without seepage holes 5-1 is located at the bottom. The part with seepage holes 5-1 improves the seepage effect, and the part without seepage holes 5-1 improves the drainage effect.

[0035] The main body of the first connector 3 is placed between the second mounting holes 2-4 of the two permeable concrete bases 2. The first connector 3 is provided with multiple first connecting pipe parts 3-11 that are inserted into the drainage holes 2-1 to connect the reinforcing pipe 5, thereby connecting the reinforcing pipe 5 in the drainage holes 2-1 of the adjacent concrete bases. The main body of the second connector 4 is placed between the second mounting holes 2-4 of the two permeable concrete bases 2. The second connector 4 is provided with multiple second connecting pipe parts 4-21 that are inserted into the drainage holes 2-1 to connect the reinforcing pipe 5. The bottom of the second connector 4 is provided with a second drainage pipe part 4-3 that extends out of the second opening groove 2-5, thereby connecting the reinforcing pipe 5 in the drainage holes 2-1 of the adjacent concrete bases and discharging rainwater to the manhole.

[0036] In the arrangement of the first connector 3 and the second connector 4, the first main body part 3-1 and the second main body part 4-2 have the same structure, so that they can be processed using the same set of molds. At the same time, the sealing end cap 3-2 seals the first insertion pipe part 3-12, and the second drain pipe part 4-3 is inserted into the second insertion pipe part 4-22 to achieve installation.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
