DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Figures 1-8 It is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0050] In the description of the utility model, it is understood that: the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included one or more features.

[0051] Please refer to Figures 1-8 The embodiments of the utility model:

[0052] Embodiments:

[0053] As Figures 1-3 shown: a kind of stable broken stone road surface cell drainage plate, comprising:

[0054] Accommodation grid 1, the hollow inside of accommodation grid 1 is arranged, for accommodating filler, accommodation grid 1 and accommodation grid 1 after upside-down interval arrangement, are fixedly connected by connecting column 2 and form the drainage plate of rectangular shape;

[0055] Clamping groove assembly, the clamping groove assembly is arranged on the two adjacent side surfaces of drainage plate whole;

[0056] Buckle assembly, the buckle assembly is arranged on the other two adjacent side surfaces of drainage plate whole;

[0057] The clamping groove assembly and buckle assembly can be mutually clamped, so that each adjacent drainage plate is connected together.

[0058] Specifically, the overall shape of accommodation grid 1 in the embodiment is a cube, and the hollow part inside is also the shape of a cube, and the overall drainage plate is a cuboid with a square surface composed of single-layer accommodation grid 1, i.e. the drainage plate is a cuboid with a square cross section, the upper and lower surfaces of the drainage plate are both square, and the side surface is rectangular.

[0059] In the embodiment, by arranging the accommodating grooves 1, the filler can be directly filled into the accommodating grooves 1 when paving the road, so that the filler better adapts to the road surface, and the paving process is more convenient and fast. In addition, the arrangement of the accommodating grooves 1 can better limit the filler and prevent the filler from flowing out. The drainage board composed of a plurality of accommodating grooves 1 can also serve as the basis for paving the road, further enhancing the overall resistance and stability of the paved road. In the embodiment, the drainage board is composed of only one type of accommodating groove 1, which is only the accommodating groove 1 inserted upside down. Overall, it is an accommodating groove of one specification, which does not require many production steps, and the production cost is low. In addition, the arrangement of the buckle assembly and the slot assembly enables each adjacent drainage board to be more stably connected, facilitating installation, and enabling the stable connection of the drainage boards in some areas to form a whole with a larger coverage area, so that the overall road surface has stronger stability.

[0060] In order to display and distinguish the features, the accommodating groove 1 placed in the normal position is shown as a first accommodating groove 13 in the figure, and the accommodating groove 1 placed upside down is shown as a second accommodating groove 14 in the figure.

[0061] As shown in Figures 2-3 Each surface of the accommodating groove 1 is provided with a hole, and the hole is in communication with the hollow part inside the accommodating groove 1.

[0062] In the embodiment, by arranging the holes on the surface of the accommodating groove 1, the filler can enter the hollow part of the accommodating groove 1 when paving the road, and water and other liquids can be easily discharged from the holes, which improves the convenience of paving the road and enables the liquid in the filler to be discharged from each hole in a timely manner. Since the filler is arranged in the accommodating groove 1, the limitation of the accommodating groove 1 on the filler will not cause the filler to flow out with the liquid when the liquid is discharged.

[0063] As shown in Figure 2 The accommodating groove 1 is hexahedrally arranged, and holes are arranged on five surfaces of the accommodating groove 1. The other surface is integrally provided with an open opening, and the opening is arranged upward on the whole drainage board. As another component unit of the drainage board, the opening on the upside-down accommodating groove 1 is arranged downward.

[0064] Specifically, in the embodiment, the open opening is specifically set as the entire surface of the surface where the hole is located as an opening, and the specific implementation of the hole is that the upper surface of the containing grid 1 placed in the positive direction is not provided with a plane, and the entire upper surface is used as a hole. For the containing grid 1 placed upside down, the hole located on the lower surface of the entire drainage plate is an open opening. In order to facilitate feature display and differentiation from other holes, the open opening hole is referred to as a third hole 15.

[0065] As shown in Figure 2 and 4 : the hole on the opposite surface of the open opening is a first hole 3, and the first hole 3 is a circular hole, and the circumferential edge of the first hole 3 is provided with a first reinforcing member 16 between the circumferential edge and the plane edge of the plane where the first hole 3 is located.

[0066] In the embodiment, the diameter of the circular hole is smaller than the minimum side length of the surface where the circular hole is located, and the first reinforcing member 16 between the circular contour of the circular hole and the surface edge can provide better limiting for the filler in the containing grid 1. That is, for the containing grid 1 placed in the positive direction, the first reinforcing member 16 can better provide support for the filler, and for the containing grid 1 placed upside down, the first reinforcing member 16 is located on the upper surface of the entire drainage plate, which can prevent the filler from overflowing from the top of the containing grid 1. The technical combination of the first reinforcing member 16 and the containing grid 1 in different placements can better limit the filler on the upper and lower surfaces, and further make the filler more stably exist in the hollow part of the containing grid 1.

[0067] As shown in Figure 2 : the other four surfaces on the containing grid 1 are side surfaces, and the holes opened on the side surfaces are second holes 4. The second hole 4 includes at least two circular arc edges, the end portions of the two circular arc edges extend to the surface edges on the plane where the two circular arc edges are located on both sides of the circular arc, the two circular arc edges and the two surface edges form the second hole 4, and the second reinforcing member 17 is arranged between the two circular arc edges and the other two edges on the surface where the two circular arc edges are located.

[0068] In the embodiment, the above content about the two circular arc edges can be understood as that the two circular arc edges and the surface edges on the plane where the two circular arc edges are located on both sides of the circular arc form the second hole 4. Specifically, in the embodiment, the second reinforcing member 17 is arranged between the edge of the circular arc opposite to the plane where the circular arc is located and the corresponding circular arc. The concave surface of the two circular arc edges in the embodiment is directed to the direction where the center of the surface is located, that is, the convex surface of the two circular arc edges is opposite to the edge of the containing grid 1.

[0069] In this embodiment, the second reinforcing member 17 is provided, which has similar effect as the first reinforcing member 16, but the first reinforcing member 16 is arranged to limit the filler on the upper and lower surfaces of the drainage plate, while the second reinforcing member 17 is arranged to limit the filler on the side surface of the drainage plate, so as to ensure that the liquid in the filler can flow out of the second hole 4, while preventing the filler from flowing out of the drainage plate along with the liquid from the inside of the containing compartment 1.

[0070] As shown in Figure 4 : the clamping groove assembly and the clamping buckle assembly are arranged on the side surface of the containing compartment 1, the number of the clamping buckle assembly and the clamping groove assembly is the same, and the clamping buckle assembly and the clamping groove assembly are arranged in corresponding positions of the respective drainage plate, so as to facilitate clamping.

[0071] Specifically, in this embodiment, four clamping buckle assemblies and four clamping groove assemblies are arranged on each drainage plate, and two are arranged on each side surface.

[0072] As shown in Figures 4-8 : the clamping groove assembly comprises:

[0073] a first connecting plate 5 fixedly connected to the side surface of the containing compartment 1, the first connecting plate 5 being provided with a first clamping groove 6 recessed towards the inside of the drainage plate;

[0074] a clamping groove group 7 comprising two first clamping grooves 6, the clamping groove group 7 being symmetrically arranged on the first connecting plate 5;

[0076] a second connecting plate 8 fixedly connected to the side surface of the containing compartment 1, the second connecting plate 8 being provided with a first clamping buckle 9 extending away from the inside of the drainage plate, and the containing compartment 1 where the second connecting plate 8 is located and the containing compartment 1 where the first connecting plate 5 is located are symmetrically arranged on the whole drainage plate;

[0077] a clamping buckle group 10 comprising two first clamping buckles 9, the clamping buckle group 10 being symmetrically arranged on the second connecting plate 8;

[0078] the first clamping buckles 9 and the first clamping grooves 6 on the adjacent two drainage plates can be clamped and connected.

[0079] Specifically, in this embodiment, the first connecting plate 5 and the second connecting plate 8 are arranged on the side surface of the respective containing compartment 1, and the arrangement of the first connecting plate 5 and the second connecting plate 8 can better connect the containing compartment 1, so as to ensure that the connection between the adjacent two drainage plates is more stable.

[0080] As shown in Figures 5-6As shown: a set of symmetrically arranged clamping groove groups 7 are arranged on the first connecting plate 5;

[0081] A set of symmetrically arranged buckles groups 10 are arranged on the second connecting plate 8.

[0082] Two first connecting plates 5 or two second connecting plates 8 are arranged on the corresponding side walls of the drainage plate.

[0083] In this embodiment, the symmetrically arranged buckle groups 10 and clamping groove groups 7 can further enhance the connection stability between the two adjacent drainage plates, because the symmetric distribution makes the force interaction more uniform.

[0084] As shown in the figure: Figures 5-8 The bottom of the first clamping groove 6 is parallel to the side of the containing compartment 1, the side walls of the first clamping groove 6 on the upper and lower surfaces of the drainage plate are both open, and the side walls between the upper and lower surfaces of the first clamping groove 6 are parallel and inclined relative to the side of the containing compartment 1.

[0087] Each buckle group 10 contains a set of symmetrically arranged first buckles 9.

[0088] In this embodiment, the side walls of the first clamping groove 6 on the upper and lower surfaces of the drainage plate are both open, which can make the connection between the groove and the buckle more convenient, that is, the first buckle 9 can be clamped into the first clamping groove 6 from above or below the first clamping groove 6, and all the clamping grooves and buckles are correspondingly arranged, so from the aspect of the clamping groove group 7, it can be understood from the above that the first clamping groove 6 is inclined relative to the side of the containing compartment 1, although its inner wall is parallel, but the two first clamping grooves 6 in each clamping groove group 7 are symmetrically arranged, that is, the inclination angles of the two first clamping grooves 6 in each clamping groove group 7 are opposite, not parallel, so even though the two inner walls of the first clamping groove 6 are parallel, the arrangement of the two first clamping grooves 6 in each clamping groove group 7 can make the clamping groove group 7 have good limiting clamping on the buckle group 10 in the horizontal direction, to ensure that each adjacent drainage plate has a stable connection relationship in the horizontal direction, and the horizontal direction is perpendicular to the side of the drainage plate.

[0089] As shown in the figure: Figures 7-8 A second buckle 11 is arranged between the two symmetrically arranged clamping groove groups 7.

[0090] The second clamping groove 12 is formed between the two adjacent clamping groups 10, and the side wall on the upper and lower surfaces of the drainage plate is provided in an open manner;
