Description

Technical Field

[0001] The utility model belongs to the technical field of municipal roads, and in particular relates to a sponge city permeable brick and a road. Background Art

[0002] "Sponge" roads refer to roads that can absorb and store water like a sponge during rainfall, and release and utilize water when needed, thereby effectively alleviating the contradiction between urban water resource shortage and urban waterlogging, and helping to repair the urban water ecological environment.

[0003] In the past, there were two methods for paving urban roads: a method of covering the entire road with paving materials and a method of paving the road with road bricks. In such urban roads, if safety and comfort are taken into consideration, it is necessary to drain rainwater and released water from the road surface as quickly as possible; generally speaking, in the method of covering the entire road with paving materials, asphalt, cement concrete and synthetic resin materials are used as the paving materials. Since such roads themselves are not water-permeable, drainage grooves provided on the shoulders are used to drain rainwater from the road surface.

[0004] On the other hand, in the method of paving with paving bricks, ceramics or cement concrete are widely used as the material of the block. Among these permeable urban road bricks, bricks with multiple large and small seepage holes are used. Water on the surface of the urban road is discharged into the underground foundation through the seepage holes. However, compared with the method of covering with paving materials, such existing permeable road bricks have excellent permeability, but their drainage function is very low during heavy rainfall. Utility Model Content

[0005] In order to solve the problems described in the background technology, the present application provides a sponge city permeable brick and road.

[0006] A sponge city permeable brick, characterized in that it includes a permeable brick body, a plurality of trapezoidal grooves are distributed in parallel on the surface of the permeable brick body, a first permeable channel for draining rainwater entering from a seepage hole is arranged in the permeable brick body, the permeable channel extends downward to a water storage chamber of the permeable brick body, and the water storage chamber is composed of a hollow cavity and a water-retaining material filled in the hollow cavity.

[0007] By adopting the above technical solution, rainwater falling on the permeable brick body flows through the seepage holes and into the water storage chamber through the first permeable channel. When the rainwater is small, the dryness of the road surface can be ensured by the water storage chamber filled with water-retaining material. Secondly, the water storage chamber is composed of a hollow cavity and the water-retaining material filled in the hollow cavity, thereby realizing the permeable function.

[0008] Optionally, the surface of the trapezoidal groove is provided with water seepage holes distributed in an array, and the first water permeable channel is connected below the water seepage holes.

[0009] Optionally, the surface of the trapezoidal groove is a water-permeable material made of a sand-based material, and the porosity of the surface of the trapezoidal groove is 35%-45%.

[0010] By adopting the above technical solution, the upper surface of the permeable brick body is an inclined surface with a low middle and high sides. When rainwater enters the permeable channel through the seepage holes, it will smoothly enter the first permeable channel located in the middle position through the diversion effect of the inclined surface, so as to further improve the water absorption and drainage effect.

[0011] Optionally, the water storage chamber is further provided with a first drainage channel arranged in parallel and penetrating between the back side of the permeable brick and the water storage chamber.

[0012] [0012 Optionally, the first drainage channel is configured to extend at the bottom of the water storage chamber.

[0013] [0013 Optionally, a second drainage channel with a sloped direction is connected to the side wall close to the water storage chamber, and the second drainage channel is connected to the surrounding soil away from the side wall of the water storage chamber.

[0014] By adopting the above technical solution, after the rainwater in the water storage chamber is full, the rainwater is discharged into the bottom soil through the first drainage channel, or discharged into the surrounding soil through the second drainage channel, thereby realizing the second utilization of the accumulated water on the road surface.

[0015] A road, characterized in that it comprises the permeable bricks for sponge cities described in any one of the above items, which are laid adjacent to each other in sequence.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1) Since a water permeable channel is set in the vertical direction and a water storage chamber is set in the horizontal direction to retain water for a specified period of time, clogging can be significantly suppressed compared to when relying solely on the water permeability of the bricks themselves, and it has excellent water permeability and drainage functions.

[0018] 2) A first drainage channel is set between the back of the permeable brick and the water storage chamber, and a second drainage channel with a slope is connected to the side wall close to the water storage chamber. After the water storage chamber is full of rainwater, the rainwater is discharged into the bottom soil through the first drainage channel, or discharged into the surrounding soil through the second drainage channel, thereby realizing the second utilization of the accumulated water on the road surface, which can significantly reduce the inconvenience caused by rapid drainage and other water overflowing the road surface.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Please refer to Figure 1 ,exist Figure 1 A sponge city permeable brick includes a permeable brick body C, a plurality of trapezoidal grooves 11 distributed in parallel on the surface of the permeable brick body C, a permeable channel for draining rainwater entering from the seepage hole is arranged in the permeable brick body C, the permeable channel extends downward to the water storage chamber of the permeable brick body C, and the water storage chamber is composed of a hollow cavity and a water-retaining material filled in the hollow cavity.

[0024] Rainwater falling on the permeable brick body C flows through the seepage holes and into the water storage chamber (not shown) through the permeable channel 12. When the rainwater is small, the dryness of the road surface can be ensured by the water storage chamber filled with water-retaining material. Secondly, the water storage chamber is composed of a hollow cavity and the water-retaining material filled in the hollow cavity.

[0025] Among them, the permeable brick body C is made of concrete permeable bricks with a water absorption rate of 3-5%. The permeable bricks have a permeable channel 12 connecting the water storage chamber and the surface of the water storage chamber. A first drainage channel 14 is formed between the bottom surface of the water storage chamber 13 and the back surface of the permeable brick body C, and a second drainage channel 15 is formed between the side wall of the water storage chamber and the surrounding soil.

[0026] Optionally, the surface of the trapezoidal groove 11 is provided with water seepage holes distributed in an array, and a water permeable channel 12 is connected below the water seepage holes.

[0027] Optionally, the surface of the trapezoidal groove 11 is a water-permeable material made of a sand-based material, and the porosity of the surface of the trapezoidal groove 11 is 35%-45%.

[0028] Optionally, the water-retaining material to be filled in the water storage chamber and the water-retaining material to be filled in the opening of the first channel are at least one of industrial slag, diatomaceous earth, sand, and fly ash.

[0029] Optionally, the water-retaining material is a permeable concrete molded body.

[0030] By adopting the above technical solution, the water storage chamber is filled with a permeable concrete molded body pressed with a water-retaining material. When the water volume or humidity in the water storage chamber increases, the ultra-fine pores on the permeable concrete molded body can automatically absorb moisture in the air and store it. If the moisture in the indoor air decreases and the humidity drops, the permeable concrete molded body wall material can release the moisture stored in the ultra-fine pores.

[0031] Optionally, the water storage chamber is further provided with a first drainage channel 14 arranged in parallel and penetrating between the back side of the permeable brick body C and the water storage chamber.

[0032] Optionally, the first drainage channel 14 is configured to extend at the bottom of the water storage chamber.

[0033] Optionally, a second drainage channel 15 with a sloped direction is connected to the side wall close to the water storage chamber, and the second drainage channel 15 is connected to the surrounding soil away from the side wall of the water storage chamber.

[0034] By adopting the above technical solution, after the rainwater in the water storage chamber is full, the rainwater is discharged into the bottom soil through the first drainage channel 14, or discharged into the surrounding soil through the second drainage channel 15, thereby realizing the second utilization of the accumulated water on the road surface.

[0035] The water storage chamber is composed of a water storage chamber formed from one side to the other side in the longitudinal direction of the brick.

[0036] The water storage chamber of the water storage chamber is as follows Figure 2 In this embodiment, the water storage chamber 1 is filled with a water retaining material.

[0037] As diatomaceous earth, its main component is silicon dioxide, which has excellent adsorption capacity and good chemical stability. Diatomaceous earth usually appears in the form of dry powder, which is placed in water and can quickly absorb water due to its porous characteristics. The water absorption rate of diatomaceous earth is generally between 70%-100%, and diatomaceous earth can appropriately respond to heavy rainfall, etc. by temporarily retaining water in the paving material to reduce sudden drainage and gradually drain water, while improving the internal water retention and preventing the formation of surface water accumulation on the permeable brick body C.

[0038] In addition, in addition to the above materials, industrial slag, fired brick chips, etc. can also be used as water-retaining materials. In particular, industrial slag produced in the industrial production process has been difficult to handle in the past, so through such use, a way to effectively utilize it can be opened.

[0039] The hollow cavity forms an elliptical cross section in the above case, but its shape can be circular, square or other shapes without particular limitation. In addition, although only the permeable channel, the first drainage channel 14 and the second drainage channel 15 connected to the hollow cavity are shown above, straight-through pipes that do not pass through the hollow cavity can also be formed on the front and back of the permeable brick body C to improve water permeability.

[0040] Rainwater and other precipitation that passes through the permeable channel falls into the water storage chamber serving as a water storage chamber, and after being temporarily retained and stored in the water-retaining material, it passes through the first drainage channel 14 or the second drainage channel 15, and is gradually released to the outside of the permeable brick body C serving as a brick, reaches the roadbed, and finally penetrates into the bottom soil or the surrounding soil, thereby realizing the water retention and drainage functions.

[0041] In the above embodiment, the case of using fired bricks is described, but blocks using diatomaceous earth or permeable concrete etc. may be used instead of bricks. In particular, when diatomaceous earth is used, its advantages are that the pavement material and the water absorption rate itself are high and the weight is also light, which can reduce transportation costs and improve construction efficiency.

[0042] Figure 2 It is a schematic diagram of the trapezoidal groove structure of sponge city permeable bricks.

[0043] The trapezoidal groove 20 includes a recess 20b, an inclined portion 20a located on both sides of the recess 20b, and the recesses 20b on both sides are arranged in parallel in the trapezoidal groove 20. The trapezoidal groove 20 is formed by making the upper surface of the permeable brick body C an inclined surface with a lower middle and higher sides. While rainwater on the surface of the permeable brick body C enters the permeable channel through the seepage holes 23, rainwater that penetrates through the permeable brick body C will smoothly enter the permeable channel located in the middle position through the diversion effect of the inclined surface, so as to further improve the water absorption and drainage effect.

[0044] The water seepage holes 23 on the surface of the concave portion 20b are connected to the water permeable channel. After the rainwater converges in the concave portion 20b, it is easy to collect water from the outside of the permeable brick body C on the surface of the permeable brick.

[0045] It is understandable that the water seepage holes 23 can also be distributed in the inclined portion 20 a of the trapezoidal groove 20 , which can increase the water permeable area and form a tree-like confluence to the water permeable channel, wherein the diameter of the water permeable channel is larger than the diameter of the water seepage holes 23 .

[0046] Finally, it should be noted that the above are only preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
