Description

Technical Field

[0001] The utility model relates to the field of pavement laying structures. More specifically, the utility model relates to a pavement laying structure based on imitation stone ceramic permeable bricks. Background Art

[0002] Ceramic permeable bricks mainly use slag waste and waste ceramics as raw materials. The ceramic raw materials are screened and selected, and a reasonable particle gradation is organized. They are formed by secondary cloth feeding under high pressure, fired at high temperature and completely vitrified, and are made to achieve the combination of high strength and high water permeability through the vitrification process. Now, ceramic permeable bricks are generally directly laid alone on the soil surface, and the permeable bricks are completely laid in contact with the soil layer. When it rains heavily, rainwater is very easy to directly wash the soil, resulting in muddy water on the road surface. Content of the Utility Model

[0003] In order to achieve these and other advantages according to the present utility model, a preferred embodiment of the present utility model provides a pavement laying structure based on imitation stone ceramic permeable bricks, which is laid above the soil layer. The pavement laying structure includes a non-woven fabric layer, a crushed stone layer, a permeable concrete layer, a dry-hardened cement mortar layer, and imitation stone ceramic permeable bricks, which are arranged in sequence from bottom to top. The thickness ratio of the crushed stone layer, the permeable concrete layer, the cement mortar layer, and the imitation stone ceramic permeable bricks is 10:15:3:6.

[0004] Preferably, the continuous porosity of the imitation stone ceramic permeable bricks is greater than 15%, the continuous porosity of the crushed stone layer is greater than 10%, the continuous porosity of the dry-hardened permeable concrete layer is greater than 10%, and the continuous porosity of the permeable concrete layer is greater than 10%.

[0005] Preferably, there are multiple imitation stone ceramic permeable bricks, and the adjacent contact surface angles between two adjacent imitation stone ceramic permeable bricks must be in the same plane.

[0006] Preferably, the surfaces of all the imitation stone ceramic permeable bricks form a slope at a certain angle to facilitate drainage.

[0007] Preferably, the surfaces of all the imitation stone ceramic permeable bricks form a slope of 2-3°.

[0008] Preferably, the gaps between two adjacent imitation stone ceramic permeable bricks are filled with filling sand.

[0009] Preferably, the imitation stone ceramic permeable brick includes an upper brick body and a lower brick body that are stacked on each other. The lower surface of the upper brick body is recessed to form a plurality of limiting grooves, and the upper surface of the lower brick body protrudes outward to form a plurality of limiting protrusions. The limiting grooves and the limiting protrusions are adapted to each other. A plurality of vertically penetrating flow channels are arranged in the upper brick body. One end of the flow channel is flush with the upper surface of the upper brick body, and the other end communicates with the gap between the upper brick body and the lower brick body.

[0010] The utility model has at least the following beneficial effects: In the pavement laying structure of the utility model, the stone-like ceramic permeable bricks are laid above the non-woven fabric layer, the gravel layer, the permeable concrete layer, and the dry-mixed mortar layer, rather than directly on the ground. On the basis of maintaining permeability, it can also play a protective role for the soil layer, avoiding direct flushing of the soil layer by rainwater, resulting in a large amount of mud and water on the ground and inconvenience for pedestrians to walk.

[0011] Other advantages, objectives, and features of the utility model will be partially reflected by the following description and partially understood by those skilled in the art through the research and practice of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following further describes the utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0015] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be applied to other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the utility model.

[0016] Those skilled in the art should understand that in the disclosure of the utility model, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the utility model.

[0017] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the number.

[0018] As Figure 1-2 shown, a preferred embodiment of the present utility model provides a pavement laying structure based on stone-like ceramic permeable bricks, which is laid above the soil layer. The pavement laying structure includes a non-woven fabric layer 2, a gravel layer 3, a permeable concrete layer 4, a dry-hardened cement mortar layer 5, and stone-like ceramic permeable bricks 6 arranged in sequence from bottom to top. The thickness ratio of the gravel layer, the permeable concrete layer, the cement mortar layer, and the stone-like ceramic permeable bricks is 10:15:3:6.

[0019] The continuous porosity of the stone-like ceramic permeable bricks is greater than 15%, the continuous porosity of the gravel layer is greater than 10%, the continuous porosity of the dry-hardened permeable concrete layer is greater than 10%, and the continuous porosity of the permeable concrete layer is greater than 10%.

[0020] In the pavement laying structure of the present utility model, the stone-like ceramic permeable bricks are laid above the non-woven fabric layer, the gravel layer, the permeable concrete layer, and the dry-hardened cement mortar layer, and are not directly laid on the ground. By using the non-woven fabric layer, on the basis of maintaining permeability, it can also play a certain protective role for the soil layer, and can avoid rainwater directly flushing the soil layer, resulting in a large amount of muddy water on the ground and causing inconvenience for pedestrians to walk.

[0021] Moreover, a drainage blind pipe 1 is horizontally placed below the non-woven fabric layer, and a plurality of drainage holes are provided on its surface to collect and discharge rainwater.

[0022] In another technical solution, the stone-like ceramic permeable bricks are multiple, and the adjacent contact surface angles between two adjacent stone-like ceramic permeable bricks must be in the same plane, and the surface is flat, which is convenient for pedestrians or non-motor vehicles to walk on.

[0023] In another technical solution, the surfaces of all the stone-like ceramic permeable bricks form a slope at a certain angle to facilitate drainage and minimize road surface water accumulation to the greatest extent.

[0024] In another technical solution, the surfaces of all the stone-like ceramic permeable bricks form a slope of 2-3°. This slope has a relatively small inclination, which can not only facilitate drainage but also does not affect pedestrians walking.

[0025] In another technical solution, the gaps between two adjacent stone-like ceramic permeable bricks are filled with joint sand to make the entire ground laying more firm.

[0026] In another technical solution, the stone-like ceramic permeable brick 6 includes an upper brick body 6-1 and a lower brick body 6-2 which are stacked on each other. A plurality of limiting grooves 6-3 are recessed in the lower surface of the upper brick body 6-1, and a plurality of limiting protrusions 6-4 protrude outward from the upper surface of the lower brick body. The limiting grooves and the limiting protrusions are adapted to each other. A plurality of vertically penetrating flow channels 6-5 are provided in the upper brick body. One end of the flow channel 6-5 is flush with the upper surface of the upper brick body, and the other end communicates with the gap between the upper brick body and the lower brick body.

[0027] In the above technical solution, the stone-like ceramic permeable brick 6 is designed to be divided into two parts, which is convenient for replacing the damaged upper brick body 6-1 in the later stage. Moreover, a plurality of flow channels are provided to facilitate drainage.

[0028] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
