Technical Field

[0001] The utility model belongs to the technical field of urban roads, and in particular relates to an urban road structure based on sponge city construction. Background Art

[0002] Sponge city refers to the adoption of adaptive measures to enable the city to absorb, store, infiltrate and purify water like a sponge when facing rainfall, and release and utilize the stored water when needed. Its purpose is to solve urban flooding problems, improve the quality of urban ecological environment and the efficiency of water resource utilization. In the actual construction process, although the existing urban roads have the function of rapid drainage, they lack corresponding means of recycling and utilizing rainwater. In addition, there is a lack of relatively automatic diversion and allocation means during the guidance of rainwater, and water accumulation still exists when the precipitation intensity is high.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a sponge-type gutter structure for urban roads [202210613081.7], which includes a sponge-type gutter and multiple rainwater storage units, the rainwater storage unit divides the sponge-type gutter into multiple gutter units, and the rainwater storage unit includes a water storage device; wherein the water storage device includes a retaining wall assembly and a drainage pipe, the retaining wall assembly includes a first retaining wall and a second retaining wall arranged at intervals in the extension direction of the sponge-type gutter, an overflow drainage well with a top opening is formed between the first retaining wall and the second retaining wall, an overflow hole connected to the sponge-type gutter is opened on the first retaining wall and the second retaining wall, the bottom of the sponge-type gutter is provided with a first drainage slope consistent with the driving direction, the drainage pipe is laid at the bottom of the overflow drainage well, a drainage hole is opened on the side wall of the overflow drainage well, and the drainage pipe is connected to the external rainwater pipeline through the drainage hole.

[0005] The purpose of the utility model is to provide an urban road structure based on sponge city construction which has a reasonable design and can automatically adjust the diversion direction in order to solve the above problems.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an urban road structure based on sponge city construction, including a support frame, a support brick is installed on the upper end of the support frame, a drainage gap is left between adjacent support bricks, a guide component opposite to the drainage gap is arranged in the support frame, a floating component opposite to the drainage gap is arranged between the support frame and the support brick, and a switching component for adjusting the flow direction of rainwater is arranged between the floating component and the drainage gap.

Support grooves are respectively opened at the intersection of the main frame and the upper ends of the corners of the support platform.

[0008] In the above-mentioned urban road structure based on sponge city construction, the main frame adopts any one or more combinations of triangular grids and polygonal grids.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, an urban road structure based on sponge city construction includes a support frame 1 laid on the ground, a support brick 2 is installed on the upper end of the support frame 1 so that the support brick 2 is isolated from the ground; a drainage gap 3 is left between adjacent support bricks 2 for rainwater to leak, a guide component 4 is arranged in the support frame 1 opposite to the drainage gap 3, and rainwater is guided to the drainage mechanism by the guide component 4, a floating component 5 opposite to the drainage gap 3 is arranged between the support frame 1 and the support brick 2, and a switching component 6 for adjusting the flow direction of rainwater is arranged between the floating component 5 and the drainage gap 3. The floating component 5 partially blocks the drainage gap 3, and the switching component 6 thereby realizes the diversion reversal, ensuring that rainwater is evenly distributed from the drainage gap 3 to the corresponding drainage structure.

[0024] Specifically, the support frame 1 includes a main frame body 11 in a grid shape, and the grid structure realizes multi-point support for the support brick 2 to ensure the installation stability of the support brick 2. A support platform 12 is arranged at the center of each grid of the main frame body 11, and support grooves 13 are respectively opened at the intersection of the main frame body 11 and the upper ends of the corners of the support platform 12. The support grooves 13 limit the corners of the support brick 2 to ensure its horizontal stability.

[0025] In depth, the main frame 11 adopts any one or more combinations of triangular grids and polygonal grids, and can select rectangular matrix grids or honeycomb grid structures according to actual needs to indicate different urban road surfaces to ensure comprehensive road coverage.

[0026] Furthermore, unlike conventional trough-type guide structures, the guide assembly 4 in the present application includes a guide cavity 41 disposed between the main frame 11 and the support platform 12, and a guide groove 42 is disposed on the top of the main frame 11 to connect adjacent guide cavities 41, and the guide groove 42 is opposite to the drainage gap 3. Each guide cavity 41 can store water independently, and when there is too much water, it is guided to the external drainage structure through the guide groove 42. Due to the different heights of the guide groove 42, the floating adjustment amount of the floating assembly 5 is also adjusted accordingly.

[0027] Furthermore, the floating assembly 5 includes a floating block 51 disposed in the diversion cavity 41, and the floating block 51 is made of a foam board. When water enters the diversion cavity 41, the floating block 51 floats up. A plurality of floating blocks 51 are arranged in a single diversion cavity 41, ensuring that the drainage gap 3 between each adjacent support brick 2 is equipped with a floating assembly 5.

[0028] In addition, the switching assembly 6 adopts a movable structure, specifically including a switching block 61 fixed on the upper end of the floating block 51, and the switching block 61 is slidably connected with the drainage gap 3. The drainage gap 3 limits the movable position of the switching block 61. When the floating assembly 5 drives the switching block 61 to move upward to block the local drainage gap 3, the excess water flows along the remaining drainage gaps 3. When the water level in the diversion cavity 41 drops, the switching block 61 is restored to ensure the normal flow of water.

[0029] At the same time, the upper end of the support brick 2 is provided with anti-skid stripes 21 to improve its anti-skid effect, and the anti-skid stripes 21 extend to the edge of the support brick 2 and guide the flow of rainwater relative to the drainage gap 3. The support brick 2 can be made of conventional masonry material, or porous material can be used to improve water permeability.

[0030] It can be seen that the upper edge of the supporting brick 2 and the top two sides of the drainage gap 3 are chamfered or rounded, and the size of the drainage gap 3 is 1.0-2.5mm. In the actual paving process, the drainage gap 3 is usually kept at 1.5mm, which ensures the surface flatness of the road structure on the one hand, and does not affect water leakage and guides drainage on the other hand.

[0031] Obviously, in order to adapt to the slope road, the support frame 1 is also tilted, and the inclination angle of the support frame 1 relative to the horizontal plane is not greater than 6.5° to avoid the slope being too large to affect the automatic distribution and guidance of the water body.

[0032] Preferably, the upper end of the support brick 2 is covered with a cushion layer 7 of loose porous material, and the cushion layer 7 has a limiting rib 71 inserted into the drainage gap 3. The cushion layer 7 has a certain elasticity, which can improve the walking comfort of pedestrians, and on the other hand, ensure the surface friction to prevent slipping. Rainwater leaks from the cushion layer 7 into the drainage gap 3, and the cushion layer 7 itself also has a certain water storage function.

[0033] In summary, the principle of this embodiment is that the support brick 2 is suspended by the support frame 1, and the guide component 4 under the support brick 2 guides the rainwater flowing into the drainage gap 3 to flow. When the water volume of the guide component 4 under the local support brick 2 is too large, the floating component 5 and the switching component 6 stage the drainage gap 3 to guide the water body to be discharged along the remaining drainage gaps 3.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although this article uses more terms such as support frame 1, main frame 11, support platform 12, support groove 13, support brick 2, anti-slip stripe 21, drainage gap 3, guide assembly 4, guide cavity 41, guide groove 42, floating assembly 5, floating block 51, switching assembly 6, switching block 61, cushion layer 7, and limiting rib 71, it does not exclude the possibility of using other terms. The use of these terms is only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
