Description

Technical Field

[0001] This invention relates to a permeable concrete pavement, and more particularly to a permeable concrete road with anti-clogging function. Background Technology

[0002] Permeable concrete is a paving material developed to address defects in existing urban roads. This material allows rainwater to seep into the ground, effectively replenishing groundwater and mitigating urban environmental problems such as a sharp drop in the water table. It also effectively eliminates the harmful effects of oil compounds and other pollutants on the surface, while protecting groundwater, maintaining ecological balance, and mitigating the urban heat island effect. It holds particular importance for promoting the healthy development of the human living environment and for urban stormwater management and water pollution control.

[0003] Existing permeable concrete roads achieve water permeability through pores, but mud, dust, and other debris carried by pedestrians and vehicles can easily clog these pores, leading to a decrease in the permeability of the permeable concrete road or even preventing it from permeating at all.

[0004] Chinese utility model patent CN207739097U discloses a permeable concrete anti-blocking structure and a concrete road. The permeable concrete anti-blocking structure comprises a filter section, a first permeable concrete layer, and a second permeable concrete layer arranged sequentially along a second preset direction. The filter section has a supporting foundation surface and a connecting surface along the second preset direction. The first permeable concrete layer has multiple vertical drainage holes spaced apart along the first preset direction, and these vertical drainage holes communicate with the filter section. The second permeable concrete layer has multiple intersecting drainage sections spaced apart along the first preset direction, and these intersecting drainage sections communicate with the vertical drainage holes. The first permeable concrete layer is detachably connected to the connecting surface.

[0005] The aforementioned utility model patent has the following problems: When pedestrians walk on the second permeable concrete layer in the rain, the mud on the soles of their shoes will enter the cross-drainage section with the rainwater, causing blockage and reducing the effectiveness of infiltration and drainage. At the same time, when it is not raining, mud, dust, and other debris on pedestrians' shoes can easily adhere to the surface of the second permeable concrete layer, making it difficult for vacuum trucks to clean the surface of the second permeable concrete layer.

[0006] Therefore, there is a need for a permeable concrete road with anti-clogging function to solve the problems of decreased permeability caused by blockage of the pores in the permeable concrete road and the difficulty in cleaning caused by the adhesion of mud and dust to the surface of the permeable concrete road. Summary of the Invention

[0007] The purpose of this invention is to provide a permeable concrete road with anti-clogging function, which can solve the problems of decreased permeability caused by blockage of the pores in the permeable concrete road and the difficulty in cleaning caused by the adhesion of mud and dust to the surface of the permeable concrete road.

[0008] This invention is implemented as follows:

[0009] A permeable concrete road with anti-clogging function includes a permeable concrete surface component, a permeable concrete base layer, and a roadbed. The permeable concrete base layer is laid on the upper surface of the roadbed. The permeable concrete surface component includes a permeable concrete surface layer, a permeable concrete intermediate layer, an absorbent layer, and percussion components. The permeable concrete intermediate layer is laid on the upper surface of the permeable concrete base layer, the absorbent layer is laid on the upper surface of the permeable concrete intermediate layer, and the permeable concrete surface layer wraps around the upper surface and sides of the absorbent layer, with the edges of the permeable concrete surface layer connected to the permeable concrete intermediate layer. Several sets of percussion components are arrayed within the absorbent layer, with the bottoms of several sets of percussion components pressing against the permeable concrete intermediate layer, and the tops of several sets of percussion components making percussion contact with the permeable concrete surface layer.

[0010] Each set of the striking components includes an elastic ring and a striking post; the elastic ring is in the form of a ring structure and is disposed in the adsorption layer, the bottom of the elastic ring presses against the upper surface of the permeable concrete intermediate layer, and the top of the elastic ring is located on the lower surface of the permeable concrete surface layer; a through hole is formed at the top of the elastic ring, the lower end of the striking post is fixed to the bottom inside the elastic ring, and the upper end of the striking post passes through the through hole to the top of the elastic ring and can strike and contact the lower surface of the permeable concrete surface layer.

[0011] The elastic ring has a through hole extension, which is coaxially connected with the through hole. The upper part of the striking post moves through the through hole extension and the through hole.

[0012] The adsorption layer contains an array of several sets of support components, which are arranged alternately with the striking components. The bottom of the support components is fixed to the upper surface of the permeable concrete intermediate layer, and the top of the support components is supported on the lower surface of the permeable concrete surface layer.

[0013] Each set of support components includes a telescopic rod and a support base; the bottom of the telescopic rod is fixed to the upper surface of the permeable concrete intermediate layer, and the top of the telescopic rod is spring-loaded in the adsorption layer and connected to the support base; the support base is supported on the lower surface of the permeable concrete surface layer.

[0014] The telescopic rod includes a spring rod, a telescopic spring, and an anti-detachment sleeve; the anti-detachment sleeve is a hollow tubular structure, with its bottom fixed to the permeable concrete intermediate layer and its top open and located below the permeable concrete surface layer; the lower end of the spring rod can be springily inserted into the anti-detachment sleeve through the telescopic spring, and the upper end of the spring rod passes through the top of the anti-detachment sleeve and is movably connected to the support base.

[0015] The spring rod has a ⊥-shaped structure. The horizontal section of the spring rod is slidably connected to the inner wall of the anti-detachment sleeve, and the width of the horizontal section of the spring rod is greater than the width of the top opening of the anti-detachment sleeve.

[0016] A cushion layer is provided between the edge of the permeable concrete surface layer and the permeable concrete intermediate layer, so that the permeable concrete surface layer is sealed and connected to the permeable concrete intermediate layer through the cushion layer.

[0017] The permeable concrete surface is wavy, with several sets of hammering components distributed at the troughs of the permeable concrete surface and several sets of support components distributed at the crests of the permeable concrete surface.

[0018] An adsorption and filtration layer is laid between the permeable concrete base layer and the permeable concrete intermediate layer.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. Because the present invention is equipped with a striking component, the elastic ring can undergo a slight downward deformation when the permeable concrete surface is subjected to pressure, thereby exposing the striking column inside the elastic ring and forming a slight tap on the permeable concrete surface. The array of striking components generates slight vibrations on the permeable concrete surface within a certain range, which helps to impact dust, dirt, etc. in the pores and on the surface of the permeable concrete, facilitating effective cleaning of the permeable concrete surface by a vacuum truck and ensuring the permeability of the permeable concrete surface.

[0021] 2. Because the present invention is equipped with a support component, the telescopic rod can expand and contract under the action of downward pressure through the telescopic spring, which plays a supporting role on the surface of permeable concrete, and plays a protective role and assists in restoring the shape of the impact component, thus ensuring the walking comfort of permeable concrete road.

[0022] 3. Because the invention has an adsorption layer and an adsorption filter layer, it can purify and adsorb infiltrated rainwater, which is beneficial to the protection of groundwater. At the same time, when subjected to downward pressure, the adsorption layer can penetrate in reverse into the permeable concrete surface, flushing away dust, soil and other impurities in the pores of the permeable concrete surface, which is beneficial for the effective cleaning of the permeable concrete surface by the vacuum truck. The adsorption layer has good deformation properties, which can form a protective enclosure for the striking component and the support component without affecting their striking and telescopic support functions.

[0023] 4. Because the present invention has a wavy permeable concrete surface, rainwater can form a flushing effect inside the wavy channel, which is conducive to washing away mud, dust and other debris on the surface of the permeable concrete, avoiding blockage of the pores of the permeable concrete surface, and facilitating the flow, discharge and infiltration of rainwater; at the same time, the wavy design can increase the anti-slip properties of the permeable concrete surface and improve the anti-slip effect.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see the appendix Figure 1 and attached Figure 2A permeable concrete road with anti-clogging function includes a permeable concrete surface component, a permeable concrete base layer 3, and a roadbed 4. The permeable concrete base layer 3 is laid on the upper surface of the roadbed 4. The permeable concrete surface component includes a permeable concrete surface layer 1, a permeable concrete intermediate layer 2, an absorbent layer 6, and percussion components. The permeable concrete intermediate layer 2 is laid on the upper surface of the permeable concrete base layer 3, and the absorbent layer 6 is laid on the upper surface of the permeable concrete intermediate layer 2. The permeable concrete surface layer 1 wraps around the upper surface and sides of the absorbent layer 6, and the edges of the permeable concrete surface layer 1 are connected to the permeable concrete intermediate layer 2. Several sets of percussion components are arrayed within the absorbent layer 6, with the bottom of the sets of percussion components pressing against the permeable concrete intermediate layer 2, and the top of the sets of percussion components making contact with the permeable concrete surface layer 1 during percussion.

[0033] Preferably, the permeable concrete surface layer 1, the permeable concrete intermediate layer 2, the permeable concrete base layer 3, and the roadbed 4 can be made of permeable concrete materials with existing technology, utilizing the pores in the permeable concrete to achieve water permeability, allowing rainwater to infiltrate, replenish groundwater, and protect the ecological environment.

[0034] Preferably, the adsorption layer 6 can be made of sponge material, which has good water absorption, permeability, and deformation capabilities. It can deform when the permeable concrete surface 1 is subjected to downward pressure such as from being stepped on, allowing the striking components to gently tap the lower surface of the permeable concrete surface 1. Within a certain area centered on the point of pressure, the permeable concrete surface 1 vibrates under the impact of multiple arrayed striking components. This helps to separate dust, dirt, and other contaminants adhering to the surface of the permeable concrete 1, and also helps to shake out dust and dirt from the pores of the permeable concrete surface 1. This facilitates effective and thorough cleaning of the surface by a vacuum truck, thereby ensuring the permeability of the road and improving the quality and efficiency of road maintenance. Simultaneously, the adsorption layer 6 encapsulates several sets of striking components, ensuring that the striking components can perform their striking action while effectively protecting them.

[0035] Please see the appendix Figure 3 Each set of the striking components includes an elastic ring 7 and a striking post 8; the elastic ring 7 is in the form of a ring and is disposed in the adsorption layer 6, the bottom of the elastic ring 7 is pressed against the upper surface of the permeable concrete intermediate layer 2, and the top of the elastic ring 7 is located on the lower surface of the permeable concrete surface layer 1; a through hole 13 is formed on the top of the elastic ring 7, the lower end of the striking post 8 is fixed to the bottom of the inner part of the elastic ring 7, and the upper end of the striking post 8 passes through the through hole 13 through the top of the elastic ring 7 and can strike and contact the lower surface of the permeable concrete surface layer 1.

[0036] Preferably, the elastic ring 7 can be made of a ring-shaped structure using elastic materials such as rubber, so that it can produce slight deformation when the permeable concrete surface layer 1 is pressed down; the striking column 8 can be made of hard materials such as plastic.

[0037] When the height of the elastic ring 7 is compressed downwards, the top of the striking post 8 located inside the elastic ring 7 protrudes relative to the through hole 13 of the elastic ring 7, thereby realizing the striking action of the top of the striking post 8 against the lower surface of the permeable concrete surface layer 1. The deformation performance of the sponge material adsorption layer 6 is better than that of the elastic ring 7, so that the elastic ring 7 is not constrained by the adsorption layer 6 when deformed, ensuring the realization of the striking action of the striking post 8 protruding relative to the elastic ring 7. When there is no downward pressure, the adsorption layer 6 and the elastic ring 7 can also return to their original position through their own elastic properties, hiding the striking post 8 inside the elastic ring 7.

[0038] Please see the appendix Figure 5 The elastic ring 7 has a through hole extension 12 formed inside, and the through hole extension 12 is coaxially connected with the through hole 13. The upper part of the striking post 8 moves through the through hole extension 12 and the through hole 13.

[0039] The length of the through hole 13 is extended by the through hole extension 12. The through hole extension 12 plays a limiting and guiding role for the striking post 8, preventing the striking post 8 from tilting or even breaking, ensuring that the striking post 8 can always be in a vertical direction and extend out of the through hole 13 or be hidden in the through hole 13.

[0040] Please see the appendix Figure 3 The adsorption layer 6 has several sets of support components arranged in an array, and the support components and the striking components are arranged alternately. The bottom of the support component is fixed on the upper surface of the permeable concrete intermediate layer 2, and the top of the support component is supported on the lower surface of the permeable concrete surface layer 1.

[0041] The support components reliably support the permeable concrete surface layer 1, facilitating the recovery of the elastic ring 7 after compression. The absorbent layer 6, wrapped around the support components, protects them without affecting their telescopic support function.

[0042] Please see the appendix Figure 3 Each set of support components includes a telescopic rod 9 and a support base 10; the bottom of the telescopic rod 9 is fixed on the upper surface of the permeable concrete intermediate layer 2, and the top of the telescopic rod 9 is spring-loaded in the adsorption layer 6 and connected to the support base 10; the support base 10 is supported on the lower surface of the permeable concrete surface layer 1.

[0043] When the permeable concrete surface layer 1 is subjected to downward pressure, the telescopic rod 9 shortens; when there is no downward pressure, the telescopic rod 9 extends and returns to its original position. The telescopic function of the telescopic rod 9 adapts to the stress deformation state of the permeable concrete surface layer 1. Simultaneously, the support seat 10 effectively supports the lower surface of the permeable concrete surface layer 1, ensuring a relatively smooth and comfortable road surface. The support seat 10 has a large contact area with the lower surface of the permeable concrete surface layer 1, resulting in high support stability.

[0044] Please see the appendix Figure 6 The telescopic rod 9 includes a spring rod 91, a telescopic spring 92, and an anti-detachment sleeve 93. The anti-detachment sleeve 93 is a hollow tubular structure. The bottom of the anti-detachment sleeve 93 is fixed on the permeable concrete intermediate layer 2, and the top of the anti-detachment sleeve 93 is open and located below the permeable concrete surface layer 1. The lower end of the spring rod 91 can be springily inserted into the anti-detachment sleeve 93 through the telescopic spring 92, and the upper end of the spring rod 91 passes through the top of the anti-detachment sleeve 93 and is movably connected to the support base 10.

[0045] When the telescopic spring 92 is subjected to force, it compresses and deforms, causing the spring rod 91 to bounce up and down relative to the anti-detachment sleeve 93, thereby realizing the telescopic function of the telescopic rod 9. It can effectively support and buffer the permeable concrete surface layer 1, and also help the elastic ring 7 to restore its shape.

[0046] Preferably, an external thread 94 is provided at the upper end of the spring rod 91, and an internal thread (not shown in the figure) is provided in the support seat 10. The support seat 10 is screwed onto the spring rod 91 by the thread, which is convenient for disassembly and assembly and has a simple structure. The spring rod 91 and the support seat 10 can also be connected by integral molding, bonding or other methods.

[0047] Please see the appendix Figure 6 The spring rod 91 has a ⊥-shaped structure. The horizontal section of the spring rod 91 is slidably connected to the inner wall of the anti-detachment sleeve 93, and the width of the horizontal section of the spring rod 91 is greater than the width of the top opening of the anti-detachment sleeve 93 to prevent the spring rod 91 from coming out of the anti-detachment sleeve 93.

[0048] Please see the appendix Figure 1 and attached Figure 2 An adsorption and filtration layer 5 is laid between the permeable concrete base layer 3 and the permeable concrete intermediate layer 2.

[0049] Preferably, the adsorption filter layer 5 can be made of activated carbon, which can adsorb harmful substances in rainwater to a certain extent, thus benefiting the protection of groundwater.

[0050] Please see the appendix Figure 4 A pad 11 is provided between the edge of the permeable concrete surface layer 1 and the permeable concrete intermediate layer 2, so that the permeable concrete surface layer 1 is sealed to the permeable concrete intermediate layer 2 through the pad 11.

[0051] Preferably, the subbase 11 can be made of materials such as silicone, with a thickness of 5mm, which has good support performance, ensures support for the edge of the permeable concrete surface layer 1, and is conducive to the deformation of the hammering component and the support component and their hammering and support functions; at the same time, it also has good sealing performance, ensuring the integrity of the road structure.

[0052] Please see the appendix Figure 1 To be continued Figure 3 The permeable concrete surface layer 1 is wavy, with several sets of hammering component arrays distributed at the troughs of the permeable concrete surface layer 1 and several sets of support component arrays distributed at the crests of the permeable concrete surface layer 1.

[0053] On the one hand, the wavy structure can improve the anti-slip effect of the permeable concrete surface layer 1, preventing pedestrians and vehicles from slipping, and also facilitating the infiltration, collection and discharge of rainwater. On the other hand, rainwater enters the wave trough from the crests on both sides, and the rainwater forms a counterflow in the wave trough, which is conducive to washing away the mud, dust and other debris on the surface of the permeable concrete surface layer 1, and preventing the pores from becoming blocked.

[0054] Please see the appendix Figure 1 To be continued Figure 6 The working principle of this invention is as follows:

[0055] When pedestrians and vehicles pass over the permeable concrete surface layer 1, the surface layer 1 is subjected to pressure, causing the telescopic spring 92 to be compressed, and the spring rod 91 to be inserted downward into the anti-detachment sleeve 93. At the same time, the elastic ring 7 also changes slightly from a circle downward into an ellipse, so that the upper end of the striking post 8 rises relative to the top of the elastic ring 7 through the through hole extension 12 and the through hole 13 and forms a slight tap on the lower surface of the permeable concrete surface layer 1. This can prevent dust, dirt, etc. from adhering to the surface of the permeable concrete surface layer 1 and prevent the pores in the permeable concrete from being blocked, thereby facilitating the dust removal and cleaning of the surface of the permeable concrete surface layer 1 by the vacuum truck.

[0056] The length of the telescopic spring 92 and its elastic coefficient, as well as the elastic coefficient of the elastic ring 7, can be selected according to the road design requirements, so that the telescopic spring 92 and the elastic ring 7 only undergo a small amount of deformation under the action of downward pressure, in order to ensure the safety and comfort of walking on the permeable concrete road.

[0057] When the permeable concrete surface layer 1 is subjected to pressure, the adsorption layer 6 is squeezed, and the sponge can better penetrate the permeable concrete surface layer 1 in the reverse direction. This helps to impact the soil, dust, etc. in the pores of the permeable concrete surface layer 1, preventing the permeable concrete surface layer 1 from being blocked, thereby ensuring the drainage and permeability functions of the permeable concrete surface layer 1.

[0058] During rainy weather, wave grooves are formed on the permeable concrete surface layer 1 with a wave-shaped structure. Rainwater enters the wave grooves from the two side crests and creates a counter-flow effect, which can further wash away dust, mud and other substances attached to the surface of the permeable concrete surface layer 1, prevent the pores of the permeable concrete from being blocked, and also has a certain anti-slip effect.

[0059] Rainwater infiltrates downwards sequentially through the permeable concrete surface layer 1, adsorption layer 6, permeable concrete intermediate layer 2, adsorption and filtration layer 5, permeable concrete base layer 3, and roadbed 4. The rainwater is adsorbed and filtered through the adsorption layer 6 and adsorption and filtration layer 5, reducing the occurrence of groundwater pollution problems.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
