Description

Technical Field

[0001] This utility model relates to the field of paving stone technology, specifically to imitation stone surface ecological paving stone. Background Technology

[0002] Imitation stone surface ecological paving stone is a type of ground paving material widely used in outdoor places such as garden landscapes, municipal squares, and residential walkways. By simulating the texture, color, and feel of natural stone, it achieves a unity of decoration and durability, and has become a commonly used ground paving product to replace natural stone.

[0003] A search revealed that Chinese utility model patent application with publication number "CN218203689U" discloses "a paving stone with a water-proof structure". By setting up a flow channel and a drainage trough, when it rains, rainwater will flow down the paving stone surface along the sloping protrusions on the side and eventually flow into the flow channel through the water-permeable holes. The rainwater is then filtered and impurities are removed by the scoop frame in the drainage trough before being discharged into the drainage pipe. By guiding the rainwater, it is not easy for rainwater to accumulate on the surface of the paving stone.

[0004] However, in actual use, the aforementioned disclosed devices and similar existing devices rely on a single flow channel or permeable hole design for their drainage structure, without fully considering the synergistic optimization of the flow path and infiltration efficiency of rainwater on the pavement. As a result, under conditions of heavy rainfall or prolonged rainfall, rainwater is prone to form local water accumulation on the raised surface of the imitation stone, and cannot quickly infiltrate through the drainage structure. Utility Model Content

[0005] The purpose of this utility model is to provide an eco-friendly stone-like surface paving stone to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Imitation stone surface eco-friendly paving stones include: The base plate is used to lay on the subgrade soil of the ground. Several processing fillers are evenly fixed on the top surface of the pavement substrate, and a drainage structure is reserved between two adjacent processing fillers. A stone-like protrusion is provided between two adjacent drainage structures. There is a height difference between the stone-like protrusion and the drainage structure. The stone-like protrusion is fixed to the top of the processed filler. As rainwater comes into contact with the surface of the imitation stone protrusion, it flows along the slope of the protrusion to the adjacent drainage structure and quickly seeps into the base soil below the pavement substrate through the water-guiding gaps in the drainage structure.

[0007] Furthermore, the drainage structure includes: The channel gap has one end set at the bottom of the raised slope of the imitation stone through the processing filler, and the other end extends along the side of the processing filler towards the edge of the paving substrate to form a discharge port.

[0008] Furthermore, the aperture of the discharge outlet gradually increases from top to bottom, allowing rainwater to collect through the channel gaps and then infiltrate into the base soil through the discharge outlet.

[0009] Furthermore, the drainage structures at the contact points of different pavement substrates are interconnected, and the discharge outlets of the drainage structures located at the top edge of the base soil are connected to the rainwater diversion channels or municipal rainwater pipe networks at the edge of the base soil to form an integrated drainage path.

[0010] Furthermore, the outer surfaces of the processing fillers located at the two opposite edges of the top surface of the plywood substrate are respectively provided with interlocking grooves and interlocking keys. The interlocking grooves and interlocking keys are compatible with each other. With the laying operation of adjacent plywood substrates, the interlocking key of one plywood substrate edge is embedded into the interlocking groove of the corresponding edge of the adjacent plywood substrate.

[0011] Furthermore, several processed fillers are connected end to end to form an adsorption filler, which is fixedly connected to the stone-like protrusions on the top surface of the processed filler. Half of them are hollow structures. The hollow stone-like protrusions are connected to the drainage structure through the connection port opened on one side of the surface. As rainwater seeps into the interior of the hollow stone-like protrusions, the rainwater continuously flows into the adjacent channel gap through the connection port and permeates into the adsorption filler.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This imitation stone ecological paving stone, through the synergistic effect of the imitation stone raised slope design and drainage structure, effectively guides rainwater to quickly converge along the slope to the channel gap, and then smoothly infiltrates into the base soil through the gradually enlarging discharge outlet, significantly improving the drainage efficiency of the paving stone. Meanwhile, half of the imitation stone protrusions adopt a hollow structure and are connected to the drainage structure through the connection port, so that rainwater can seep into the absorbent filling formed by the processed filling body, which increases the retention time and penetration depth of rainwater, which is conducive to the survival of microorganisms in the base soil and the growth of plant roots, and enhances the ecological restoration function of the paving stones. In addition, the adjacent flooring substrates form a stable connection structure through the precise matching of interlocking grooves and interlocking keys, which improves the overall anti-displacement ability of the flooring and avoids loosening or widening of gaps after long-term use. The uniform distribution of the processed filler, combined with the three-dimensional shape of the stone-like protrusions, not only ensures the compressive strength of the paving stone, but also highly replicates the texture and feel of natural stone.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Before understanding the technical solution proposed in this application, it should be clear that this technical solution is mainly applied in outdoor paving scenarios such as urban garden landscape walkways, municipal public squares, and residential courtyards, which need to simultaneously meet the needs of landscape decoration and ecological environmental protection. It is proposed to address the technical problems that traditional imitation stone paving stones generally have, such as low drainage efficiency, rainwater cannot naturally infiltrate and replenish groundwater, easy water accumulation on the surface leading to the risk of pedestrians slipping, and lack of ecological function.

[0017] like Figure 1 As shown, the first assembly structure of this solution includes: Surface substrate 1: As a basic support structure, the bottom surface is directly laid and attached to the base soil of the ground, providing a stable installation base for the entire system.

[0018] Several processed fillers 5 are fixed to the top surface of the pavement substrate 1. The key point is that a specific interval space is reserved between two adjacent processed fillers 5, which constitutes the structural basis for drainage. It should be noted that in this technical solution, the processed filler 5 is specifically a block structure made of high-strength imitation stone resin and natural stone particles mixed and pressed.

[0019] Stone-like protrusion 2: It is positioned between two adjacent drainage structures and reliably fixed to the top of the processed filler 5. A significant height difference exists between the surface of the stone-like protrusion 2 and its adjacent drainage structure, forming a slope conducive to drainage. It should be noted that when rainwater falls onto the surface of the stone-like protrusion 2, it will naturally flow downwards along its pre-set slope and eventually merge into the adjacent drainage structure. After entering the drainage structure, rainwater can quickly infiltrate through the water-conducting gaps within the structure, penetrating the pavement substrate 1 and reaching the underlying base soil for effective infiltration.

[0020] As a supplement to the above, the specific components of the drainage structure in this technical solution include: Channel gap 3: One end of it starts at the lowest point of the slope of the imitation stone protrusion 2, which is defined by the adjacent processed filler 5. The other end of the channel gap 3 extends along the side of the processed filler 5 towards the edge of the pavement substrate 1 and finally forms the discharge port 4.

[0021] It is worth noting that the diameter of the outlet 4 is designed to gradually increase from top to bottom, forming a funnel-like shape. This design helps to collect rainwater transported from the channel gap 3 and further improves the efficiency of rainwater infiltrating downward into the base soil through this outlet.

[0022] It should also be noted that in this technical solution, when multiple paving substrates 1 are laid and in contact with each other, the drainage structures (especially the channel gaps 3 and the discharge outlets 4) located at their contact edges can be connected and aligned with each other. In addition, for the paving substrates 1 laid at the top edge of the base soil, the discharge outlets 4 at the end of their drainage structures will be precisely connected to the rainwater diversion channels or municipal rainwater pipe networks pre-set at the edge of the base soil. Through this connection method, the originally independent unit drainage paths are integrated into a continuous and integrated drainage path, ensuring the orderly collection and discharge of rainwater.

[0023] refer to Figure 2 As can be seen, in the second assembly structure proposed in this application, the external assembly structure of the plywood substrate 1 further includes: at two opposite edges on the top surface of the plywood substrate 1, the outermost processing filler 5 is respectively provided with a fitting groove 6 and a fitting key 7, and the two are matched in shape and size. It should be added that when laying adjacent plywood substrates 1, the operator can accurately insert the fitting key 7 on the edge of one plywood substrate 1 into the fitting groove 6 on the corresponding edge of the adjacent plywood substrate 1. This interlocking design not only simplifies the installation process, but also ensures that the connection between adjacent substrates is stable and the position is accurate.

[0024] refer to Figure 3It is understood that in the third assembly structure proposed in this application, the external assembly structure of the pavement substrate 1 further includes: several processed fillers 5 connected end to end in a specific area to jointly enclose a continuous adsorption filling area 8, and the stone-like protrusions 2 fixedly connected to the top surface of the processed fillers 5 in this area, half of which are designed as hollow structures, wherein the hollow stone-like protrusions 2 have an associated opening 9 on one side of their surface, and the associated opening 9 is directly connected to the drainage structure below (specifically, the channel gap 3 area).

[0025] It is worth noting that when rainwater seeps into the interior of these hollow stone-like protrusions 2, it will continuously flow into the adjacent channel gaps 3 through the associated openings 9. Some of the water will also seep into and be temporarily stored in the adsorption filling material 8 around the channel gaps 3 during the flow process. It should be added that in this technical solution, both the adsorption filling 8 and the processed filling 5 are surface-modified zeolite particles or lightweight ceramsite.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
