[0004] However, in the above-mentioned permeable board, the permeable holes are arranged at intervals, and the top surface of the permeable board is a flat structure, resulting in that when rainwater falls on the top surface of the permeable board, only part of the water flow directly above and near the permeable holes can be discharged downward through the permeable holes, while rainwater between the top openings of the permeable holes is easy to remain on the surface of the permeable board, reducing the permeability and efficiency; not only that, the above-mentioned permeable board needs to use steel bars to penetrate the positioning holes to fix the board body to prevent the board body from being misplaced and causing the connection to become loose. The fixing operation of the permeable board is cumbersome and requires the use of other tools, which affects the efficiency of the laying construction of the permeable board.

DETAILED DESCRIPTION

[0035] 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.

[0036] First embodiment

[0037] like Figure 1-Figure 8 As shown, the water-permeable board of the first embodiment of the utility model is used for paving a road surface, and includes a water-permeable board 1, wherein the water-permeable board 1 has a relative paving surface 11 and a pressure-bearing surface 12, and a plurality of water-permeable through holes 2 are arranged on the water-permeable board 1, and the two ends of the water-permeable through holes 2 extend to the paving surface 11 and the pressure-bearing surface 12 respectively, and a guide groove 3 is also arranged on the pressure-bearing surface 12, and the water-permeable through holes 2 are connected through the guide groove 3.

[0038] In order to ensure the structural strength and environmental protection of the water-permeable board, the water-permeable board of this embodiment uses EPP board, which is a material made of polypropylene plastic foam. It is not only recyclable and reused, but also can be naturally degraded and will not cause white pollution. In addition, the EPP board has excellent physical properties, such as waterproof and moisture-proof, strong impact resistance, high strength and strong toughness. To be more specific, the water-permeable board in this embodiment has a molding density of 82g / l, a compression strength of 530kPa, a compression permanent deformation rate of 8.5%, a bending strength of 1090kPa, and a water absorption rate of 0.02g / cm 3 .

[0039] When the permeable board 1 is in normal use, the paving surface 11 is at the bottom, which is the bottom surface of the permeable board 1 and contacts the concrete layer of the pavement structure; the pressure-bearing surface 12 is at the top, which is the top surface of the permeable board 1 and contacts the pavement pavement layer of the pavement structure to withstand the pressure from above.

[0040] The water-permeable plate 1 is densely covered with water-permeable through holes 2, which are circular through holes, and the direction of their axial center lines is consistent with the thickness of the water-permeable plate 1. In order to enhance the water permeability of the water-permeable plate 1 and enhance the water permeability, a guide groove 3 is arranged on the pressure-bearing surface 12, and both ends of the guide groove 3 are connected to the water-permeable through holes 2, so that two adjacent water-permeable through holes 2 are connected through the guide groove 3. In this way, when rainwater falls on the pressure-bearing surface 12, most of the rainwater can flow along the guide groove 3, and finally enter the inner side of the water-permeable through hole 2, and be discharged downward through the water-permeable through hole 2. In this way, it is convenient for rainwater on the pressure-bearing surface 12 to quickly fall to the bottom of the water-permeable plate 1, avoiding rainwater from remaining on the pressure-bearing surface 12 of the water-permeable plate 1, thereby improving the water permeability efficiency and enhancing the water permeability effect.

[0041] A further improvement is that the guide grooves 3 are densely distributed on the pressure-bearing surface 12 .

[0042] The densely distributed guide grooves 3 increase the possibility of rainwater entering the guide grooves 3 after falling on the pressure surface 12 of the permeable plate 1, thereby facilitating the rainwater to flow along the guide grooves 3 and be discharged downward through the permeable through holes 2, thereby ensuring the water permeability efficiency and avoiding most of the water remaining on the pressure surface 12.

[0043] A further improvement is that the water-permeable through holes 2 and / or the guide grooves 3 are evenly distributed on the pressure-bearing surface 12 .

[0044] Specifically, the water-permeable through holes 2 and the guide grooves 3 are evenly distributed on the pressure-bearing surface 12 to form a mesh structure, so that the structural distribution of the water-permeable plate 1 is evenly and symmetrically distributed, ensuring that the structural strength of the water-permeable plate 1 is uniform everywhere, avoiding excessive structural differences caused by position differences of the water-permeable plate 1, resulting in reduced structural stability of the water-permeable plate 1 and easy damage.

[0045] A further improvement is that an interlocking piece 4 is provided on the circumferential outer edge of the water-permeable board 1, and the interlocking piece 4 is used to interlock and connect adjacent water-permeable boards 1 when the water-permeable boards are laid.

[0046] When laying the permeable board, the interlocking parts 4 arranged on the circumferential outer edge of the permeable board 1 itself make the interlocking parts 4 of two adjacent permeable boards 1 interlock and connect, and then interlock and connect the two adjacent permeable boards 1. In this way, the permeable boards 1 can be locked with each other without the aid of other tools to prevent the position of the permeable boards 1 from shifting, thereby ensuring the stability of the position of the permeable layer formed by laying. The interlocking connection between the interlocking parts 4 facilitates the rapid interlocking connection between the permeable boards 1, thereby quickly laying a permeable layer, which is beneficial to improving the construction efficiency of laying.

[0047] A further improvement is that the interlocking member 4 includes matching interlocking recesses 41 and interlocking protrusions 42 , and both the interlocking recesses 41 and the interlocking protrusions 42 are in the shape of long strips, extending along the length direction of the side walls of the corresponding water-permeable plate 1 .

[0048] Specifically, in this embodiment, the water-permeable plate 1 is a square plate structure, and the connection forms of the circumferential outer edge interlocking member 4 of the water-permeable plate 1 and the water-permeable plate 1 mainly include two types. The first type is as follows: Figure 1-Figure 4 As shown, the four side walls of the circumferential outer edge of the permeable plate 1 are provided with interlocking recesses 41, which are flush with the paving surface 11 and face the plane where the pressure-bearing surface 12 is located. The interlocking recesses 41 are interlocking grooves extending along the length direction of the side wall where they are located. Figure 5-Figure 8 As shown, interlocking protrusions 42 are provided on the four side walls of the circumferential outer edge of the permeable board 1. The interlocking protrusions 42 are flush with the pressure-bearing surface 12 and face the plane where the paving surface 11 is located. The interlocking protrusions 42 are interlocking convex strips and extend along the length direction of the side wall where they are located.

[0049] After adopting the above structure, when the water-permeable sheet material 1 is used to lay and form a water-permeable layer, the water-permeable sheet material 1 with the interlocking recess 41 and the water-permeable sheet material 1 with the interlocking protrusion 42 are placed together, and the interlocking protrusion 42 is inserted downward into the interlocking recess 41, so that the adjacent water-permeable sheets 1 can be interlocked and connected; according to the above method, the water-permeable sheets 1 are laid and arranged, that is, the water-permeable sheet material 1 with the interlocking recess 41 has a water-permeable sheet material 1 with the interlocking protrusion 42 on either side, and correspondingly, the water-permeable sheet material 1 with the interlocking protrusion 42 has a water-permeable sheet material 1 with the interlocking recess 41 on either side, and the interlocking cooperation between the interlocking recess 42 and the interlocking protrusion 41 is used to realize the interlocking splicing of two adjacent water-permeable sheets 1, and finally form a structure as shown in the figure. Fig. 9 The interlocking recess 41 is an interlocking groove extending along the length direction of the side wall where it is located, and the interlocking protrusion 42 is an interlocking convex strip extending along the length direction of the side wall where it is located. After adopting the above structure, the length of the interlocking recess 41 and the interlocking protrusion 42 is increased, thereby increasing the interlocking contact area after the two are connected, strengthening the stability of the structure formed by splicing two adjacent permeable panels 1, and preventing the permeable panels 1 from deflecting.

[0050] A further improvement is that the water-permeable through hole 2 includes an edge water-permeable hole 21 arranged on the interlocking piece 4.

[0051] Specifically, the water-permeable through hole 2 includes an edge water-permeable hole 21 and a central water-permeable hole 22. The edge water-permeable hole 21 is arranged on the interlocking member 4 and is adjacent to the circumferential side wall of the water-permeable plate 1. The edge water-permeable holes 21 are connected in sequence to form a rectangular closed-loop structure, and the central water-permeable hole 22 is located on the inner side of the above-mentioned closed-loop structure. After adopting the above-mentioned structure, on the one hand, it is ensured that the water-permeable through holes 2 are evenly distributed on the water-permeable plate 1, which is conducive to ensuring the uniformity of the distribution of the structural strength of the water-permeable plate 1. On the other hand, it expands the distribution range of the water-permeable through holes 2 and increases the overall length of the guide groove 3, which is more conducive to the guide groove 3 on the water-permeable plate 1 receiving the water flow on the pressure-bearing surface 12 and guiding the water flow to the central water-permeable hole 22 and the edge water-permeable hole 21, thereby improving the water permeability efficiency of the water-permeable plate 1.

[0052] like Fig. 9 As shown, the main structure of the water-permeable layer based on this embodiment is shown, and the water-permeable layer is formed by splicing the water-permeable panels of this embodiment.

[0053] Since the guide groove 3 is provided on the pressure-bearing surface 12 of the water-permeable plate 1, the guide groove 3 connects the water-permeable through holes 2, so that after rainwater falls on the pressure-bearing surface 12 of the water-permeable plate 1, most of the rainwater can be guided to the water-permeable through holes 2 through the guide groove 3, and then discharged through the water-permeable through holes 2, thereby avoiding most of the accumulated water remaining on the pressure-bearing surface 12, thus ensuring the water permeability efficiency; and the water-permeable through holes 2 are densely distributed on the pressure-bearing surface 12, and the water-permeable through holes 2 include edge water-permeable holes 21 adjacent to the edge of the water-permeable plate 1 and central water-permeable holes 22 located between the edge water-permeable holes 21, thereby ensuring the coverage range of the water-permeable through holes 2 and the overall length of the guide groove 3, which is more conducive to receiving the accumulated water on the pressure-bearing surface 12 and guiding the accumulated water to the water-permeable through holes 2 for downward discharge.

[0054] In addition, an elongated interlocking piece 4 is provided on the circumferential outer edge of the permeable plate 1, and the interlocking pieces 4 of two adjacent permeable plates 1 are interlocked and connected, and the interlocking protrusion 42 is inserted into the interlocking recess 41 to ensure that the two adjacent permeable plates 1 are interlocked and stably connected. The interlocking piece 4 is an elongated structure, which increases the interlocking contact area, strengthens the stability of the connection between adjacent permeable plates 1, and prevents the position of the permeable plates 1 from shifting. Since no other external tools are required when laying the permeable layer, costs are saved and construction is convenient and quick, which is conducive to improving the laying construction efficiency.

[0055] It should be noted that the water-permeable board of this embodiment is suitable for paving both permeable and non-permeable pavements.

[0056] Second embodiment

[0057] like Figure 10-12 As shown, the water-permeable plate of the second embodiment of the present invention is based on the first embodiment, and the difference lies in that the interlocking recess 41 and the interlocking protrusion 42 are arranged on two opposite side walls of the water-permeable plate 1 .

[0058] Specifically, in the present embodiment, since the water-permeable sheet material 1 is a square plate-like structure, on the four side walls at its circumferential outer edge, two adjacent side walls are provided with two interlocking recesses 41 in one-to-one correspondence, and the remaining two adjacent side walls are provided with two interlocking protrusions 42 in one-to-one correspondence. In this way, the interlocking recesses 41 and the interlocking protrusions 42 on the water-permeable sheet material 1 are provided in pairs, and the water-permeable sheet material 1 itself has the interlocking recesses 41 and the interlocking protrusions 42.

[0059] Therefore, after adopting the above structure, when laying the permeable layer, only one permeable board needs to be prepared, that is, Figure 10-12 When two adjacent permeable panels are spliced ​​together, the interlocking protrusion 42 on one permeable panel 1 is inserted into the interlocking recess 41 on the other permeable panel 1, so that the two adjacent permeable panels 1 can be interlocked and connected. Figure 13-Figure 16The permeable layer is formed by a layer of water-permeable board. In this way, when laying, there is no need to deliberately prepare two kinds of water-permeable boards, which is more conducive to rapid construction and avoids the waste of some water-permeable boards caused by inconsistent preparation quantities of different water-permeable boards, thereby saving costs.

[0060] A further improvement is that the guide groove 3 includes an edge groove 31 arranged on the interlocking part 4, the edge groove 31 extends along the length direction of the side wall of the corresponding permeable plate 1, and the two sides of the notch of the edge groove 31 are respectively arranged on the pressure-bearing surface 12 and the circumferential side wall of the permeable plate 1.

[0061] Specifically, the guide groove 3 includes an edge groove 31 and a center groove 32 , wherein the edge groove 31 is located on the side wall of the permeable plate 1 and extends along the length direction of the corresponding side wall, the edge groove 31 is a through groove, and the center groove 32 is located between the edge grooves 31 around the permeable plate 1 .

[0062] After adopting the above structure, when two adjacent water-permeable plates 1 are spliced ​​together, the edge grooves 31 at the splicing position of the two adjacent water-permeable plates 1 are combined to form a new drainage groove, such as Fig.16 As shown, when rainwater falls on the pressure-bearing surface 12 of any water-permeable plate 1, the flow of rainwater is further facilitated through the edge groove 31, the center groove 32 and the drainage groove, which is conducive to the rainwater entering the water-permeable through hole 2 and falling downward, thereby accelerating drainage and improving water permeability efficiency.

[0063] like Figure 13-Figure 16 As shown, the main structure of the water-permeable layer based on this embodiment is shown, and the water-permeable layer is formed by splicing the water-permeable panels of this embodiment.

[0064] Since the water-permeable board 1 is a square plate-like structure, two interlocking recesses 41 and two interlocking protrusions 42 are respectively arranged on its four side walls in a one-to-one correspondence. Therefore, when laying a water-permeable layer, only the same kind of water-permeable board 1 needs to be prepared to avoid material waste caused by inconsistent preparation of different kinds of water-permeable boards 1, and when splicing, only the interlocking protrusion 42 of one of the two adjacent water-permeable boards 1 needs to be interlocked with the interlocking recess 41 of the other to complete the interlocking connection of the two adjacent water-permeable boards 1, which is easy to operate and conducive to improving construction efficiency. In addition, the guide groove 3 also includes an edge groove 31 arranged on the interlocking part 4. After the two adjacent water-permeable boards 1 are spliced, the edge grooves 31 at the splicing position are combined with each other to form a drainage groove, which is more conducive to the flow of rainwater on the pressure surface 12 of the water-permeable board 1, and it is convenient for rainwater to be discharged through the water-permeable through hole 2, thereby ensuring the water permeability efficiency.

[0065] 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.
