It can make water penetrate quickly in the brick body and reduce surface runoff, thereby reducing the risk of urban waterlogging. It also has the functions of air purification, cooling and noise reduction by planting green grass, which helps to improve the urban environment.

[0003] In the prior art, for example, a Chinese utility model patent with announcement number CN213295941U discloses a grass-planting brick, which uses a connecting block that is lower than the top surface of a pressure strip to provide additional growth space for the green grass in the grass-planting hole, thereby reducing the possibility of the green grass being crushed by pedestrians and vehicles, further improving its survival rate, and also reducing the amount of materials used in the production of grass-planting bricks, thereby reducing production costs.

[0004] Although the above-mentioned grass bricks utilize the snap-in blocks to achieve interlocking connection on the paving surface to ensure the stability of the grass pavement, the grass bricks are independent of each other in the height direction and each bears the pressure from above, which results in the need to increase the thickness of the grass bricks in order to ensure the structural strength, thereby increasing the production cost; in addition, in the grass pavement paved with the above-mentioned grass bricks, the grass holes and grass openings are separated and independent from each other, water cannot flow through, and water cannot be evenly distributed in the grass holes and grass openings, affecting the survival and growth of green plants in the grass holes and grass openings.

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figure 1-Figure 5 As shown, the high-strength grass-planting permeable brick of the utility model comprises a grass-planting brick body 1;

[0031] The grass-planting brick body 1 has a grass-planting hole 11 extending along the thickness direction of the brick body;

[0032] A pressure diffusion unit 2 is arranged at the circumferential outer edge of the grass planting brick body 1. The pressure diffusion unit 2 includes a pressure-applying part 21 and a pressure-receiving part 22 on one side. The pressure-applying part 21 and the pressure-receiving part 22 are arranged back to back on two opposite side walls of the circumferential outer edge of the grass planting brick body 1. The bottom surface of the pressure-applying part 21 and the top surface of the pressure-receiving part 22 are located in the same plane.

[0033] When the high-strength grass-planting permeable brick is placed horizontally, the projection of the grass-planting brick body 1 on the horizontal plane is in the shape of a "well", and the projection of the grass-planting hole 11 on the horizontal plane is a square, and the interior of the grass-planting hole 11 is used to plant green grass; different from the prior art, a pressure-applying member 21 and a pressure-receiving member 22 are arranged in the circumference of the grass-planting brick body 1, and the pressure-applying member 21 and the pressure-receiving member 22 are arranged back to back and are respectively located on the opposite sides of the grass-planting brick body 1, and the bottom surface of the pressure-applying member 21 and the top surface of the pressure-receiving member 22 are located in the same plane, so that when the two grass-planting brick bodies 1 are spliced ​​with each other, the bottom surface of the pressure-applying member 21 on one of the grass-planting brick bodies 1 The surface is in contact with the top surface of another grass brick body 1. Therefore, when one of the grass brick bodies 1 is subjected to pressure from above, the pressure can be diffused to the other grass brick body 1 through the pressure diffusion unit 2. By adopting the above method, the pressure diffusion unit 2 is utilized to make the grass brick bodies 1 on the entire paving surface jointly bear the pressure from above. In this way, the pressure originally borne by the grass brick body 1 can be reduced. Then, on the basis of reducing the thickness of the grass brick body 1 to reduce the amount of production materials and reduce the production cost, it is achieved that both strength is taken into account and the possibility of breaking and damage of the grass brick body 1 due to excessive pressure is reduced.

[0034] A further improvement is that the pressure diffusion units 2 are evenly distributed on four sides of the circumferential outer edge of the grass-planting brick body 1 , so as to enclose and form the grass-planting opening 3 after adjacent grass-planting brick bodies 1 are spliced.

[0035] Specifically, the pressure diffusion units 2 are distributed at the four corners of the grass-planting brick body 1 , and the pressure-applying members 21 and the pressure-receiving members 22 are both strip-shaped structures, extending along the length direction of one of the side walls of the grass-planting brick body 1 .

[0036] More specifically, the lengths of the pressure member 21 and the pressure member 22 are consistent with the length of the grass-planting hole 11. Thus, the grass-planting brick body 1 can be spliced ​​to form a Figure 6-Figure 8The grass-planted permeable pavement shown in the figure has four grass-planted brick bodies 1 distributed in a rectangular array and spliced ​​in sequence to form a grass-planted permeable pavement. The grass-planted permeable pavement has four grass-planting holes 11 and five grass-planting openings 3. The four grass-planting holes 11 are possessed by the four grass-planting brick bodies 1 themselves and are distributed in a rectangular array. The five grass-planting openings 3 are distributed in a "cross" shape and are located between the four grass-planting holes 11. The size of the grass-planting openings 3 is consistent with that of the grass-planting holes 11, and the inside of the grass-planting openings 3 is also used to plant green grass to improve the road environment. The four grass-planting holes 11 and the five grass-planting openings 3 are distributed in a 3*3 rectangular array and have consistent structural dimensions, which is conducive to ensuring the aesthetics of the grass-planted pavement.

[0037] It should be noted that the number of grass-planting brick bodies 1 is not limited to the above four, and the number of grass-planting brick bodies 1 can be adjusted according to laying needs.

[0038] A further improvement is that a pressure groove 211 is provided on the bottom surface of the pressure-applying member 21, and a pressure groove 221 is provided on the top surface of the pressure-receiving member 22. The pressure groove 211 and the pressure-receiving groove 221 are used to combine to form a water-permeable channel 23 connected to the grass planting opening 3 when adjacent grass-planting brick bodies 1 are spliced.

[0039] The pressure grooves 211 are evenly spaced along the length direction of the pressure piece 21, and the pressure grooves 211 are through grooves extending along the width direction of the pressure piece 21, and the cross section is a semicircular opening downward. Similarly, the pressure grooves 221 are evenly spaced along the length direction of the pressure piece 22, and the pressure grooves 221 are through grooves extending along the width direction of the pressure piece 22, and the cross section is a semicircular opening upward. The cross-sectional radius of the pressure groove 211 is consistent with the cross-sectional radius of the pressure groove 221. In this way, when two adjacent grass planting brick bodies 1 are spliced ​​with each other, the notch of the pressure groove 211 on the pressure piece 21 in one of the grass planting brick bodies 1 is directly opposite to the notch of the pressure groove 221 on the pressure piece 22 in the other grass planting brick body 1, and the pressure groove 211 and the pressure groove 221 are combined to form a Figure 6 The permeable channel 23 shown is used to interconnect the grass planting openings 3, which helps to evenly distribute the water flow in the grass planting openings 3. The even distribution of the water flow is more conducive to the survival and growth of the green grass in the grass planting openings 3, and avoids excessive or insufficient water flow in some grass planting openings 3.

[0040] A further improvement is that a grass planting channel 13 extending to the circumferential outer edge of the grass planting brick body 1 is provided on the circumferential inner wall of the grass planting hole 11 .

[0041] Specifically, three cylindrical grass-planting passages 13 are provided on either side of the grass-planting hole 11, and the grass-planting brick bodies 1 are spliced ​​to form a grass-planting passage 13. Figure 6-Figure 8After the grass-planted permeable pavement is formed, water flows between the grass-planting holes 11 and the grass-planting openings 3, which helps to evenly distribute the water in the grass-planting holes 11 and the grass-planting openings 3, improve the survival rate of the green grass on the inner walls of the grass-planting holes 11 and the grass-planting openings 3, and thus improve the pavement ecological environment.

[0042] A further improvement is that one of the circumferential outer edge of the grass planting brick body 1 and the end of the pressure diffusion unit 2 away from the circumferential outer edge of the grass planting brick body 1 is provided with an interlocking recess 24, and the other is provided with an interlocking protrusion 12. The interlocking recess 24 and the interlocking protrusion 12 are used to interlock and connect adjacent grass planting brick bodies 1 when adjacent grass planting brick bodies 1 are spliced.

[0043] Specifically, two interlocking protrusions 12 are provided on the four sides of the grass planting brick body 1, and the two interlocking protrusions 12 extend along the thickness direction of the grass planting brick body 1, one of the interlocking protrusions 12 is located directly below the pressure-applying piece 21, and the other interlocking protrusion 12 is located directly above the pressure-receiving piece 22; in the pressure diffusion unit 2, the pressure-applying piece 21 and the pressure-receiving piece 22 are provided with an interlocking recess 24 at one end away from the grass planting hole 11, and the interlocking recess 24 is an interlocking through groove extending along the thickness direction of the grass planting brick body 1.

[0044] After adopting the above structure, when two grass planting brick bodies 1 are spliced ​​together, the interlocking protrusion 12 on the circumferential outer edge of one of the grass planting brick bodies 1 is inserted into the interlocking recess 24 at the end of the pressure-applying piece 21 (or the pressure-receiving piece 22) of the other grass planting brick body 1, thereby realizing the interlocking connection between the two adjacent grass planting brick bodies 1, ensuring the structural stability between the grass planting brick bodies 1 on the paving surface, and avoiding relative displacement and loosening between the grass planting brick bodies 1.

[0045] A further improvement is that the grass planting brick body 1 includes two laying brick bodies 4 distributed along the thickness direction of the grass planting brick body 1, and the structures, shapes and sizes of the two laying brick bodies 4 are consistent; matching plug-in protrusions 41 and plug-in recesses 42 are arranged between the two laying brick bodies 4, and the plug-in protrusions 41 and the plug-in recesses 42 are plug-fitted along the thickness direction of the grass planting brick body 1.

[0046] Specifically, Figure 1 and Figure 4As shown, the paving brick body 4 includes four paving strips connected in one piece, and the four paving strips are respectively two transverse paving strips and two longitudinal paving strips, the two transverse paving strips are parallel in length direction, the two longitudinal paving strips are parallel in length direction, the ends of the transverse paving strips are connected in one piece with the middle part of the longitudinal paving strips, and the ends of the longitudinal paving strips are connected in one piece with the middle part of the transverse paving strips, so that the two transverse paving strips and the two longitudinal paving strips are enclosed to form a square frame structure, and four convex strips are arranged at the four corners of the square frame structure, and the center of the square frame structure is the grass planting through hole 45. When the two paving brick bodies 4 are laid along their own thickness direction, the grass planting through holes 45 of the two paving brick bodies 4 are connected in turn to form the grass planting hole 11 of the grass planting brick body 1, and the convex strips located at the top form the pressure-applying member 21, and the convex strips located at the bottom form the pressure-bearing member 22; interlocking protrusions 12 are arranged at the four corners of the square frame structure; and the four paving strips are arranged at one end away from the square frame structure. Interlocking recesses 24 are arranged.

[0047] Moreover, the upper and lower surfaces of the four paving strips are provided with grooves which are spaced apart along their length direction and extend along their width direction. The groove located on the top surface is the top surface groove 44, and the groove located on the bottom surface is the bottom surface groove 43. The top surface groove 44 and the bottom surface groove 43 are arranged back to back and have the same size. When the upper and lower paving brick bodies 4 are connected in sequence along the height direction, the top surface groove 44 and the bottom surface groove 43 are combined to form a grass-planting channel 13. In addition, the bottom surface groove 43 on the lower paving brick body 4 helps the water flow between the grass-planting hole 11 and the grass-planting mouth 3, while the top surface groove 44 on the upper paving brick body 4 helps the water flow into the grass-planting hole 11 and the grass-planting mouth 3, thereby guiding the water flow, increasing the roughness of the grass-planting permeable pavement, enhancing the anti-slip performance, and ensuring the safety of pedestrians walking on the grass-planting permeable pavement.

[0048] In addition, the ends of the four paving strips away from the grass planting through hole 45 are provided with pressure grooves which are spaced apart along their own length direction and extend along their own width direction, which have similar functions to the top groove 44 and the bottom groove 43. The pressure groove on the bottom surface of the upper pressure-applying member 21 is the pressure groove 211, and the pressure groove on the top surface can increase the roughness of the grass-planted permeable pavement, while the pressure groove on the top surface of the lower pressure-bearing member 22 is the pressure groove 221, and the pressure groove on the bottom surface helps the water flow between the grass planting openings 3, so that the water flow is evenly distributed between the grass planting hole 11 and the grass planting opening 3, which helps to improve the survival rate of the green grass.

[0049] The top and bottom surfaces of one pair of diagonal corners of the square frame structure are both provided with hemispherical plug-in protrusions 41, and the top and bottom surfaces of the remaining pair of diagonal corners are both provided with hemispherical plug-in recesses 42. The plug-in protrusions 41 are matched with the plug-in recesses 42, so that after the upper and lower laying brick bodies 4 are spliced ​​along the height direction, the plug-in protrusions 41 are inserted into the plug-in recesses 42 to connect the two laying brick bodies 4 to form a grass-planting brick body 1, thereby preventing the laying brick body 4 from offsetting and sliding in the laying surface direction, thereby ensuring the stability of the grass-planting brick body 1 structure.

[0050] Moreover, since the structures, sizes and shapes of the two paving brick bodies 4 are consistent, any one of the paving brick bodies 4 can be selected to form the grass-planting brick body 1, and then another paving brick body 4 can be laid on top of the paving brick body 4 to form the grass-planting brick body 1, that is, only one kind of production raw material needs to be prepared, avoiding excessive preparation of raw materials and avoiding waste caused by excessive preparation of a certain paving raw material, thereby increasing the possibility of cost. When actually paving a grass-planting permeable pavement, a layer of paving brick body 4 can be laid first, and then another layer of paving brick body 4 can be laid on the paving brick body 4, so that when the upper and lower paving brick bodies 4 are combined to form the grass-planting brick body 1, the paving strips in the upper paving brick body 4 in the adjacent grass-planting brick bodies 1 can be pressed down on the paving strips of the other paving brick body 4, thereby realizing pressure diffusion and reducing the pressure borne by itself to ensure structural strength.

[0051] 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.
