TECHNICAL FIELD

[0001] The present application relates to the technical field of slope protection, and in particular to a slope protection device and a paving method. BACKGROUND

[0002] In slope protection engineering, traditional methods often rely on masonry, concrete pouring or installation of prefabricated parts to build protection structures. However, these methods have exposed a series of technical problems and limitations in practical application. First, the natural conditions of slopes are complex and variable, with significant differences in soil strength, slope, moisture conditions and climate conditions in different regions.

[0006] To achieve the above objectives, the specific solution adopted by the present invention is as follows:

[0007] A slope protection device includes multiple protection units arranged in an array, with adjacent protection units detachably connected via a connecting unit. Each protection unit includes a planting surface layer, a reinforcing middle layer, and a base layer arranged sequentially from top to bottom.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, the present invention first provides a slope protection device, including multiple protection units 1 arranged in an array, and adjacent protection units 1 are detachably connected by a connecting unit. The protection unit 1 includes a planting surface layer, a reinforcing middle layer and a foundation bottom layer arranged sequentially from top to bottom. The planting surface layer includes a first frame 2, the reinforcing middle layer includes a second frame 3, and the foundation bottom layer includes a third frame 4. The first frame 2, the second frame 3 and the third frame 4 are all provided with connecting holes 5 extending in the thickness direction. The connecting unit includes a first connecting plate 16, a second connecting plate 19 and two connecting pipes 12 that can be inserted into the connecting holes 5. The first connecting plate 16 is fixedly connected to two positioning sleeves 13, and the second connecting plate 19 is fixedly connected to two insert rods 17. The positioning sleeves 13 and the insert rods 17 can be inserted into the connecting pipes 12 from both ends, and the insert rods 17 can be inserted into the positioning sleeves 13.

[0032] During production, 3D printing technology can be used to create flexible planting surfaces, reinforcing middle layers, and foundation layers, giving the protective unit 1 deformability. This allows it to better conform to the slope, improving the protective effect and making construction easier without requiring significant adjustments to the slope. The materials used in 3D printing can be flexible plastics, engineering plastics, bioplastics, PA materials, and rubber-based composites, all of which are conventional materials and will not be elaborated further. When using the protective device of this invention to protect a slope, the number and distribution of the protective units 1 needed are first determined based on the actual conditions of the slope. The protective units must fully cover the slope, avoiding large gaps. Based on the deformable protective units 1 created using 3D printing technology, the protective units 1 can deform to better cover the slope. Next, the third frame 4 of the foundation layer is fixed to the slope using conventional methods such as anchor bolts. If necessary, a mounting base plate can be fixed to the edge of the third frame 4 and secured with anchor bolts. After the third frame 4 is fixed, permeable granules are filled into the inside of the third frame 4 to ensure the permeability of the protective unit 1. Then, the reinforcing middle layer and the second frame 3 are placed on the third frame 4, and a bearing block is filled into the inside of the second frame 3 to improve the bearing capacity of the protective unit 1. Subsequently, the first frame 2 of the planting upper layer is placed on the second frame 3, and planting soil is filled into the inside of the first frame 2. Finally, the first frame 2, the second frame 3, and the third frame 4 of the protective unit 1 are connected using a connecting unit, thereby connecting two adjacent protective units 1. Specifically, the connecting pipe 12 is passed through the connecting holes 5 on the first frame 2, the second frame 3, and the third frame 4 in sequence, thereby using the connecting pipe 12 to limit and connect the first frame 2, the second frame 3, and the third frame 4 into a whole. In two adjacent protective units 1, two adjacent connecting pipes 12 are connected by a first connecting plate 16 and a second connecting plate 19. Specifically, by inserting a positioning sleeve 13 and a plug rod 17 into the connecting pipe 12, and inserting the plug rod 17 into the positioning sleeve 13, the connecting pipe 12 can be connected to the first connecting plate 16 and the second connecting plate 17, thus achieving the connection of two adjacent protective units 1. The connecting unit of the present invention has a simple structure and adopts a structure separate from the protective unit 1. The first frame 2, the second frame 3, and the third frame 4 of the protective unit 1, as well as the connecting unit, can be produced and transported separately, making it easier to implement and reducing costs. During the installation process, two adjacent protective units 1 can also be easily connected together.

[0033] The protective unit 1 of this invention can be produced using 3D printing technology, thus possessing flexibility and being better able to be laid on slopes, ensuring full coverage of the slope and thus guaranteeing the protective effect. The protective unit 1 of this invention adopts a three-layer structure: a planting surface layer, a reinforcing middle layer, and a foundation bottom layer, which respectively achieve the effects of planting vegetation, enhancing load-bearing capacity, and ensuring drainage performance, providing stable protection for the slope and enhancing greening. The connecting unit of this invention has a simple structure and adopts a structure separate from the protective unit 1. The first frame 2, the second frame 3, and the third frame 4 of the protective unit 1, as well as the connecting unit, can all be produced and transported separately, making it easier to implement and reducing costs. During the paving process, it is also convenient to connect two adjacent protective units 1 together.

[0034] like Figure 3 and Figure 4 As shown, the specific structure of the planting surface is as follows: Multiple upper partition plates 6 are fixedly installed on the inner side of the first frame 2, dividing the inner cavity of the first frame 2 into multiple planting areas. These planting areas are filled with planting soil for planting plants. A first tray 7 is fixedly connected to the bottom surface of the first frame 2. When planting soil is filled into the inner side of the first frame 2, it is evenly distributed to each planting area and supported by the first tray 7. Plants are then planted in these areas. This ensures that the planting soil inside the first frame 2 is evenly distributed, preventing the center of the protective unit 1 from shifting due to uneven distribution, which would prevent successful installation on the slope. It also controls the spacing between plants, ensuring their normal growth.

[0035] Furthermore, the multiple upper partitions 6 are evenly divided into two groups, with the two groups of upper partitions 6 perpendicular to each other. The junction of the upper partitions 6 forms a junction section, on which drainage holes 8 extending along the thickness direction of the first frame 2 are provided, and the drainage holes 8 penetrate the first tray 7. During rainfall, rainwater can accumulate in the planting area, continuously providing water to the plants after the rainfall ends, ensuring normal plant growth. When rainfall is excessive, the excess rainwater can overflow from the top of the upper partitions 6 into the drainage holes 8, and then flow downwards through the drainage holes 8, preventing excessive rainwater accumulation inside the first frame 2, which would cause the plant roots to be soaked in rainwater for a long time, thus preventing plant growth restriction or even death.

[0036] Furthermore, a distance is left between the upper partition plate 6 and the top surface of the first frame 2 to form a mixing area. When the rainfall is heavy and rainwater overflows from the planting area, the overflowing rainwater can enter the drainage hole 8 from the mixing area instead of flowing directly out from the surface of the planting layer. This allows the rainwater to infiltrate downwards, preventing the water flow from carrying away some of the planting soil and causing a decrease in the amount of planting soil in the planting area, which in turn affects the growth of the plants.

[0037] The specific structure of the reinforced middle layer is as follows: the second frame 3 is filled with a bearing block, and a second tray 9 for supporting the bearing block is fixedly installed on the bottom surface of the second frame 3, and multiple through holes 10 are evenly opened on the second tray 9. The bearing block can be filled with graded crushed stone or mixed material as needed, which plays a role in load transfer and preventing the loss of the upper soil layer.

[0038] The specific structure of the foundation layer is as follows: multiple lower partition plates 11 are fixedly installed on the inner side of the third frame 4. These lower partition plates 11 divide the inner cavity of the third frame 4 into multiple permeable areas, which are filled with permeable particles. The permeable particles can be large-diameter, highly permeable materials such as gravel and slag, which serve to drain water, filter water, and reinforce the foundation. This ensures both permeability and the stability of the foundation layer structure, thereby ensuring the structural stability of the protective unit 1.

[0039] like Figure 6 As shown, to further ensure the structural stability of the connecting unit, a bushing 15 is provided inside the positioning sleeve 13. The bushing 15 has an insertion hole into which the insertion rod 17 can be inserted. The opening end of the insertion hole has a flared end 14 for guiding the insertion rod 17. The second connecting plate 19 is fixedly connected to the insertion rod 17 via a positioning post 18. The positioning post 18 can be inserted into the connecting tube 12 and fits tightly against the inner wall of the connecting tube 12. The bushing 15 can be made of an elastic material such as rubber, and there is an interference fit between the bushing 15 and the insertion rod 17, i.e., the bushing 15 clamps the insertion rod 17, ensuring its stable position and preventing disassembly of the connecting unit. By providing the flared end 14, the inner wall of the flared end 14 guides the insertion rod 17 during insertion into the insertion hole, ensuring smooth insertion and preventing displacement.

[0040] Furthermore, to improve the overall drainage performance of the device and prevent the protective unit 1 from becoming loose due to excessive local water accumulation, the device includes several water supply pipes 21, which can pass between two adjacent protective units 1. By setting up the water supply pipes 21, excess rainwater can be directly discharged through the protective unit 1 to the outside of the slope, avoiding damage to the protective unit 1.

[0041] To facilitate the installation of the water supply pipe 21, receiving grooves 20 are provided on the outer periphery of the first frame 2, the second frame 3, and the third frame 4, allowing the water supply pipe 21 to be inserted into the receiving grooves 20. During installation, the water supply pipe 21 can be placed into the receiving groove 20 before connecting two adjacent protective units 1. The receiving grooves 20 on two adjacent protective units 1 cooperate to form a channel that can accommodate the water supply pipe 21, thus completing the installation of the water supply pipe 21. The water supply pipes 21 can be connected using conventional connectors. Correspondingly, expansion sections can be provided at both ends of the receiving groove 20, and the connectors can be placed in the expansion sections.

[0042] The present invention also provides a method for paving a slope protection device, comprising S1 to S4.

[0044] S2. Based on the distribution method, the protection unit 1 is arranged on the slope.
