Technical Field

[0001] The utility model relates to the technical field of permeable bricks, in particular to a permeable paving block and a permeable pavement. Background Art

[0002] Permeable bricks have good water permeability and air permeability. They can allow rainwater to quickly penetrate into the ground, replenish soil water and groundwater, maintain soil moisture, and improve the living conditions of urban ground plants and soil microorganisms. On the other hand, permeable bricks can absorb moisture and heat, regulate the temperature and humidity of local surface spaces, and play a major role in regulating urban microclimate and alleviating the urban heat island effect.

[0003] Most of the permeable bricks in the prior art are like the permeable bricks disclosed in the Chinese utility model with announcement number CN209227321U and CN212714340U, which have permeable holes on the surface of the brick body to facilitate the introduction of rainwater into the ground, and interlocking structures are set around the brick body to avoid positional displacement after the permeable bricks are laid. However, in the above permeable bricks, due to the limited number of permeable holes and the limited area of ​​the permeable holes, the permeable performance of the permeable bricks is limited, and some rainwater is easily left on the top surface of the permeable bricks, increasing the humidity of the permeable pavement, making it easy for pedestrians on the permeable pavement to slip and fall, posing certain safety hazards; moreover, due to the fixed structure of the permeable bricks, the thickness of the permeable pavement is limited, and the thickness of the permeable pavement cannot be adjusted according to the height position of the foundation.

[0004] Therefore, it is necessary to improve the permeable bricks and permeable pavement in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects in the prior art and provide a permeable paving block and a permeable pavement which increase the water permeability, ensure the safety of pedestrians and facilitate the adjustment of the thickness.

[0008] An interlocking piece is arranged on the circumferential outer edge of the permeable brick, and the interlocking piece is used to interlock and connect adjacent permeable bricks when the permeable bricks are laid on the same plane.

[0009] Preferably, in order to facilitate laying, the projections of the guide grooves on the two permeable surfaces along the thickness direction of the permeable bricks overlap.

[0010] Preferably, in order to facilitate manufacturing and facilitate rainwater to penetrate into the ground, the axial direction of the permeable through hole is parallel to the thickness direction of the permeable brick.

[0011] Preferably, in order to enhance the water permeability of the permeable pavement, both ends of the guide groove extend to the circumferential outer edge of the permeable brick, and after the permeable bricks are interlocked and connected by the interlocking parts, the guide grooves on the same permeable surface of adjacent permeable bricks are connected.

[0012] Preferably, in order to achieve interlocking connection between the permeable bricks, the interlocking parts include matching interlocking protrusions and interlocking recesses.

[0013] Preferably, in order to facilitate the paving of the permeable pavement, the number of the interlocking protrusions and the interlocking depressions is equal and corresponds one to one.

[0014] Preferably, in order to facilitate the adjustment of the overall thickness, at least two of the permeable bricks are provided, which are stacked in sequence along the thickness direction thereof.

[0015] Preferably, in order to avoid mutual offset between two adjacent permeable bricks in the height direction, a positioning member is provided between the two adjacent permeable bricks, and the positioning member includes a positioning protrusion and a positioning recess provided on the two permeable surfaces.

DETAILED DESCRIPTION

[0040] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0041] First embodiment

[0042] like Figure 1-Figure 3 As shown, the permeable paving block of the first embodiment of the utility model includes a permeable brick 1, the outer surface of the permeable brick 1 includes two permeable surfaces 2 distributed along the thickness direction of the permeable brick 1, at least two permeable through holes 3 are arranged on the permeable brick 1, the two ends of the permeable through holes 3 extend to the two permeable surfaces 2 respectively, and the two permeable surfaces 2 are both provided with guide grooves 4, and the permeable through holes 3 are connected through the guide grooves 4; the circumferential outer edge of the permeable brick 1 is provided with an interlocking piece 5, and the interlocking piece 5 is used to interlock and connect adjacent permeable bricks 1 when the permeable bricks 1 are laid on the same plane.

[0043] Specifically, when the permeable brick 1 of this embodiment is laid flat, its projection on the horizontal plane is square as a whole, the spacing between the two side walls in the circumferential outer edge of the permeable brick 1 is 650 mm, and the top and bottom surfaces of the permeable brick 1, that is, the spacing between the two permeable surfaces 2 is 120 mm, and nine permeable through holes 3 are arranged on the permeable brick 1, and the permeable through holes 3 are distributed in a rectangular array. Among the nine permeable through holes 3, the permeable through hole 3 located at the center has the largest inner diameter, the permeable through holes 3 located at the four corners have the second largest inner diameter, and the remaining four permeable through holes 3 have the smallest inner diameter. Six guide grooves 4 are arranged on the two permeable surfaces 2, and the six guide grooves 4 are distributed in a mesh shape, and the groove length direction is parallel to the length direction of a certain side of the permeable brick 1, the groove width of the guide groove 4 is smaller than the inner diameter of the permeable through hole 3, and the nine permeable through holes 3 are interconnected through the six guide grooves 4. Of course, according to the needs of road paving, the permeable brick 1 can also be of other shapes, and the size of the permeable brick 1, the number, diameter, and distribution of the permeable holes 3, and the number and distribution of the guide grooves 4 can also be of other types.

[0044] After the permeable brick 1 is laid flat, one of the permeable surfaces 2 is the top surface of the permeable brick 1. Compared with the permeable paving blocks in the prior art, by setting the guide groove 4 on the permeable brick 1, the rainwater falling on the surface of the permeable brick 1 can be guided to flow to the permeable through hole 3, which is convenient for introducing the rainwater into the underground. In this way, the permeable performance of the permeable brick 1 is enhanced, and the residual amount of rainwater on the top surface of the permeable brick 1 is greatly reduced, and the permeable road surface is prevented from being wetted and increasing the possibility of pedestrians slipping when walking on the top surface of the permeable brick 1. In this way, the safety of the permeable brick 1 is increased; in addition, due to the design of the guide groove 4, the roughness of the permeable surface 2 of the permeable brick 1 is increased, which further ensures safety. Not only that, it also reduces the amount of production materials used for the permeable brick 1, reduces production costs and reduces weight, and facilitates transportation.

[0045] A further improvement is that the projections of the guide grooves 4 on the two permeable surfaces 2 along the thickness direction of the permeable brick 1 overlap. With the above design, the permeability of the two permeable surfaces 2 of the permeable brick 1 is consistent. When paving a permeable road surface, any one of the permeable surfaces 2 can be selected as the bottom surface of the permeable brick 1, and the other permeable surface 2 can be selected as the top surface of the permeable brick 1, so that it is convenient and quick to lay.

[0046] A further improvement is that the axial direction of the water-permeable through hole 3 is parallel to the thickness direction of the water-permeable brick 1. With this design, the water-permeable brick 1 is formed quickly, and at the same time, when the water-permeable road surface is paved, rainwater flowing to the top of the water-permeable through hole 3 can fall quickly along the vertical water-permeable through hole 3, thereby enhancing the water-permeability.

[0047] A further improvement is that both ends of the guide groove 4 extend to the circumferential outer edge of the permeable brick 1. After the permeable bricks 1 are interlocked and connected through the interlocking parts 5, the guide grooves 4 on the same permeable surface 2 of adjacent permeable bricks 1 are connected.

[0048] After adopting this design, the length of the guide groove 4 is increased, which is convenient for guiding rainwater to the permeable through hole 3. Figure 6-Figure 8 In the permeable pavement shown, the guide grooves 4 between adjacent permeable bricks 1 are interconnected, so as to facilitate the flow of rainwater on the top surface of the permeable bricks 1 to enter the permeable through holes 3 and then seep into the ground.

[0049] A further improvement is that the interlocking member 5 includes matching interlocking protrusions 51 and interlocking recesses 52; the number of the interlocking protrusions 51 and the interlocking recesses 52 are equal and correspond one to one.

[0050] Specifically, in the present embodiment, two interlocking protrusions 51 and two interlocking recesses 52 are provided, and the interlocking protrusions 51 are provided on two opposite side walls of one pair of the permeable bricks 1, and the interlocking recesses 52 are provided on the other opposite side walls; after adopting this structural design, during the paving process of the permeable bricks 1, the interlocking protrusions 51 of one permeable brick 1 are inserted into the interlocking recesses 52 of another permeable brick 1, thereby achieving interlocking cooperation and avoiding the horizontal displacement between the permeable bricks 1; in addition, since the number of interlocking protrusions 51 and interlocking recesses 52 on the permeable bricks 1 is equal and one-to-one corresponding, when paving the permeable pavement, it is only necessary to select a single type of permeable bricks 1 to interlock and connect the permeable bricks 1. Compared with other permeable bricks 1 with mismatched numbers of interlocking protrusions 51 and interlocking recesses 52, there is no need to consider the number distribution problem of the permeable bricks 1, and the waste of paving materials caused by excessive permeable bricks 1 with too many interlocking protrusions 51 or interlocking recesses 52 is avoided.

[0051] A further improvement is that at least two permeable bricks 1 are provided and stacked in sequence along the thickness direction thereof.

[0052] like Figure 4 and Figure 5 As shown, by adopting this design, the permeable bricks 1 are stacked in sequence, and the overall thickness of the permeable paving block can be adjusted, so as to facilitate the selection of different numbers of permeable bricks 1 to be stacked according to different heights of the road surface. In this embodiment, three permeable bricks 1 are laid. In actual use, the number of permeable bricks 1 can also be selected according to the specific conditions of the road surface. In addition, since the projections of the guide grooves 4 on the two permeable surfaces 2 on the same permeable brick 1 along the thickness direction of the permeable brick 1 coincide, between two adjacent permeable bricks 1, the guide grooves 4 on the bottom permeable surface 2 of the permeable brick 1 at a high position and the guide grooves 4 on the top permeable surface 2 of the permeable brick 1 at a low position cooperate with each other to form a diversion channel. The diversion channel can not only guide the water flow to the permeable through hole 3 on the permeable brick 1 at the low position, but also has a temporary water storage function to avoid the permeable paving block from draining slowly when the rain is too heavy, resulting in a large amount of water remaining on its top. In this way, the amount of rainwater residue on its top is reduced to ensure the safety of pedestrians.

[0053] This embodiment also discloses a permeable pavement, such as Figure 6-Figure 8 As shown, the above-disclosed permeable paving blocks are sequentially spliced ​​and arranged on the same plane. For the top surface of the permeable brick 1 at the highest position of the permeable paving block, since the guide groove 4 is set, it is convenient to receive rainwater and guide the rainwater to the permeable through hole 3, so that the rainwater passes through the permeable through holes 3 at other positions in turn and seeps into the ground.

[0054] Second embodiment

[0055] like Fig. 9 and Fig.10As shown, the permeable paving block of the second embodiment of the utility model is based on the first embodiment, and the difference is that a positioning member 6 is arranged between two adjacent permeable bricks 1, and the positioning member 6 includes a positioning protrusion 61 and a positioning recess 62 arranged on the two permeable surfaces 2.

[0056] After adopting the above improvement, when two permeable bricks 1 are stacked along the thickness direction thereof, the positioning protrusion 61 is inserted into the positioning recess 62, thereby preventing the two permeable bricks 1 from being offset in the horizontal direction after being laid.

[0057] Specifically, four positioning protrusions 61 are distributed at the four corners of one of the permeable surfaces 2, and positioning recesses 62 corresponding to and matching the four positioning protrusions 61 are distributed at the four corners of the other permeable surface 2. In order to facilitate demoulding, the positioning protrusions 61 are hemispherical.

[0058] After adopting the above structure, the permeable bricks 1 are stacked in sequence along their thickness direction as follows: Fig.11 He Ru Fig.12 The permeable paving blocks and the permeable bricks 1 are interlocked and connected to avoid deviation.

[0059] like Fig.13 and Fig.14 As shown, a permeable pavement is formed by paving the above-mentioned permeable paving blocks. Compared with the permeable pavement disclosed in the first embodiment, since the permeable bricks 1 are interlocked and connected by positioning protrusions 61 and positioning recesses 62, the permeable bricks 1 are prevented from positional displacement, making the permeable pavement structure more stable.

[0060] Third embodiment

[0061] like Fig.15 and Fig.16 As shown, the permeable paving block of the third embodiment of the utility model is based on the second embodiment, with the difference that a permeable groove 7 is further provided on the circumferential outer edge of the permeable brick 1, and the two ends of the permeable groove 7 extend to the two permeable surfaces 2 respectively and are connected with the guide grooves 4 on the two permeable surfaces 2.

[0062] Specifically, since six guide grooves 4 are provided and distributed in a mesh shape, the permeable grooves 7 are provided at the ends of the guide grooves 4, and there are twelve in total, and three permeable grooves 7 are provided on any side wall of the circumferential outer edge of the permeable brick 1, and the permeable grooves 7 are through grooves extending along the thickness direction of the permeable brick 1. In this way, when the permeable bricks 1 are stacked up and down in sequence to form Fig.17 and Fig.18 After the permeable paving block is formed, two adjacent permeable grooves 7 are connected to each other. Finally, the permeable grooves 7 are connected in sequence to form a permeable channel. When it rains, rainwater falling on the top surface of the permeable paving block can also enter the permeable groove 7 along the guide groove 4, fall along the permeable groove 7, and seep into the ground, further enhancing the permeability.

[0063] like Fig.19 and Fig. 20 As shown, a permeable pavement is formed by paving the permeable pavement blocks mentioned above. Compared with the permeable pavement disclosed in the second embodiment, the permeable area is increased due to the design of the permeable groove 7, and the permeable performance of the permeable pavement is further enhanced.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
