Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated block paving, in particular to a green and water-retaining interlocking block for slope protection. Background Art

[0002] Slope protection refers to the protection of slopes exposed to the atmosphere from damage such as spalling, fragmentation, erosion, or surface soil collapse. It is a general term for various paving and planting methods applied to slopes. Functionally, it serves only as a protective layer against weathering and erosion, and this protective layer generally does not bear lateral earth pressure. Slope protection types are generally categorized as plant protection, skeleton plant protection, and engineering protection, each with its own applicable conditions depending on the application scenario. High-quality development of engineering construction emphasizes that engineering design should integrate ecological concepts and promotes green design in slope protection design, aiming to achieve both protective functions and natural integration with the surrounding environment. Skeleton plant protection combines the advantages of both plant protection and engineering protection. Its superior protective function and greening effects, as well as its low cost, ease of construction, aesthetic appearance, and wide range of applicability, have led to its widespread use in water conservancy, highway, and railway projects. Cement concrete hollow precast blocks are one of the most commonly used skeleton types, with commonly used concrete hollow hexagonal blocks and porous interlocking blocks.

[0003] The main disadvantages of existing prefabricated hollow cement concrete block skeletons are: (1) the planting hole area of ​​the hollow hexagonal block is large, and soil loss is serious under rain erosion, which reduces the protective effect; (2) the design of porous structure interlocking blocks generally emphasizes functions such as block strength, expanding the planting hole area, and enhancing drainage, but lacks in-depth consideration of plant coverage and water retention. As a result, after the grass seedlings grow, they often cannot completely cover the block surface, and the bricks are obviously exposed, which affects the greening effect, especially in the dry season when there is a lack of water, which can easily cause the grass seedlings to wither.

[0004] In order to solve the above problems, it is necessary to develop a green and water-retaining interlocking block that has high green coverage, stable interlocking structure and superior ecological performance. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a fully green and water-retaining interlocking block for slope protection. The structure not only needs to meet the requirements of natural ecology and landscape aesthetics, but also should focus on construction convenience and long-term economic efficiency, especially in the scenarios of slope protection and comprehensive greening, to play a greater technical advantage.

[0006] In order to solve the above technical problems, the utility model provides a green and water-retaining interlocking block for slope protection, which is used to be laid in a concrete slope protection frame and includes at least one main locking block and at least four side blocks;

[0007] The main lock block includes four vertically connected rectangular frames. Among adjacent two rectangular frames, the short side of one rectangular frame is connected to the middle of the long side of the other rectangular frame to form a whole, and the two long sides of the two rectangular frames cooperate to form an L-shaped lock edge groove. A lock edge convex part is arranged at the end of the long side of the L-shaped lock edge groove. The lock edge convex part and the L-shaped lock edge groove cooperate to form a lock edge groove. The lock edge convex part and the end of the rectangular frame cooperate to form a lock edge plug. The lock edge plug is used to be embedded into the lock edge groove for limit cooperation; the four rectangular frames cooperate to form a middle through hole;

[0008] The side block is arranged in the lock edge groove between the main lock block and the concrete slope protection frame.

[0009] Further, an avoidance groove is arranged in the middle of the lock edge plug, and an avoidance angle is arranged at one end of the lock edge plug on the side far from the lock edge convex part.

[0010] Further, the two included angles in the avoidance groove are obtuse angles.

[0011] Further, the included angle between the lock edge convex part and the long side of the rectangular frame is an obtuse angle.

[0012] Further, the side block is a "艹" character structure with six fulcrums.

[0013] Further, chamfered bevels are arranged on the outer periphery of the surface of the main lock block, on the inner periphery of the surface of the rectangular frame, and on the surface of the middle through hole.

[0014] Further, the chamfered height of the chamfered bevel is 1 cm and the inclination angle is 45°.

[0015] Further, both the main lock block and the side block are integrally prepared by a mold.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) The windmill-type interlocking structure splicing type of the main interlocking block can form a stable interlocking effect, significantly enhance the anti-slip ability and the overall structural stability.

[0018] (2) The grooves and holes are in the form of small openings with uniform hole distances, ensuring that the shortest distances between the planting holes are basically the same, ensuring that the grass seedlings can evenly cover the interlocking blocks. The chamfered bevel form on the top surface of the interlocking blocks ensures that the grass seedlings grow fully and smoothly, improves the greening coverage rate, achieves the effect of "seeing no bricks but only grass", forms a continuous lawn-like landscape, and perfectly integrates with the natural environment, enhancing the greening effect and aesthetics.

[0019] (3) The form of small openings with uniform hole distances increases the slope coverage rate of the interlocking block body, reduces the slope soil loss rate, improves the water and soil conservation performance of the slope soil, and is beneficial to the growth of grass seedlings in the dry season.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 3 As shown, an embodiment of the green and water-retaining interlocking block for slope protection of the present invention is used for laying in a concrete slope protection frame, and includes at least one main locking block 1 and at least four side blocks 2;

[0027] The main locking block includes four vertically connected rectangular frames 3, and rectangular through holes 4 are provided in the rectangular frames. In the two adjacent rectangular frames, the short side of one rectangular frame is connected to the middle part of the long side of the other rectangular frame as a whole, and the two long sides of the two rectangular frames cooperate to form an L-shaped locking groove, which is a windmill-shaped structure. The long side end of the L-shaped locking groove is provided with a locking protrusion 5, which cooperates with the L-shaped locking groove to form a locking groove 6, and the locking protrusion cooperates with the end of the rectangular frame to form a locking plug 7. The locking plug is used to be embedded in the locking groove for cooperation and limitation. In the long side direction, the locking groove limits both sides; the four rectangular frames cooperate to form a middle through hole 8; the side block is arranged in the locking groove between the main locking block and the concrete slope protection frame to form a stable interlocking structure.

[0028] An avoidance groove 9 is also provided in the middle of the locking plug. After splicing, a first through hole is formed between the avoidance groove and the adjacent edge. An avoidance angle 10 is provided at the end of the locking plug on one side away from the locking protrusion. After splicing, a second through hole is formed between the avoidance angle and the adjacent edge.

[0029] Through the coordination of the middle through hole, the rectangular through hole, the first through hole and the second through hole, a small opening pattern with uniform hole spacing is formed. After the grass is planted, the grass growth can completely cover the interlocking blocks, achieving a coherent lawn effect.

[0030] The two included angles in the avoidance groove are obtuse angles, and the included angle between the edge-locking convex part and the long side of the rectangular frame is an obtuse angle, ensuring the strength between adjacent structures, reliable force-bearing, and also forming a through-hole structure, further increasing the hole rate between adjacent components, avoiding the inability to plant grass at the abutting position, and forming a large area of shielding. The edge block is a "艹" character structure with six fulcrums. The edge block is spliced with the main locking block through the fulcrums, serving as a medium for connecting the main locking block and the boundary. Moreover, the structure of the edge block can also provide holes for planting grass, improving the grass-planting area at the edge while ensuring the effective force-bearing strength and avoiding the problem of no vegetation at the edge.

[0031] Chamfer斜边11 is provided on the outer periphery of the surface of the main locking block, the inner periphery of the surface of the rectangular frame, and the surface of the middle through-hole, ensuring that the grass seedlings grow fully and舒展, and increasing the greening coverage rate. Specifically, both the main locking block and the edge block are integrally prepared by a mold. The chamfer height of the chamfer斜边 is 1 cm and the inclination angle is 45°. While meeting the greening coverage rate, it ensures the preparation quality and service quality.

[0032] Refer to Figure 3 As shown, a locking block structure can be formed by a single main locking block and four edge blocks. Through the cooperation of the through-hole on the surface of the main locking block and the edge block, it achieves good force-bearing effects and a large greening coverage rate.

[0033] Refer to Figure 4 As shown, the external rectangular dimension of the main locking block is 39.6 cm × 39.6 cm, the total thickness is 4 cm, the bottom dimension of the rectangular frame is 16.5 cm × 3.5 cm, the bottom dimension of the middle through-hole is 2.4 cm × 2.4 cm, and the maximum thickness of the hole wall is 4.3 cm; the external rectangular dimension of the edge block is 22.8 cm × 8.5 cm, the total thickness is 4 cm; the chamfer height of the upper part of the main locking block and the edge block is both 1 cm, and the inclination angle is 45°; taking the example of 2 × 1 main locking blocks with 6 edge blocks, the hole rate of the splicing unit can reach 31.2%.

[0034] Refer to Figure 5 As shown, the external rectangular dimension of the main locking block is 29.6 cm × 29.6 cm, the total thickness is 4 cm, the bottom dimension of the rectangular frame is 11.8 cm × 2.5 cm, and the maximum thickness of the hole wall is 4.0 cm; the external rectangular dimension of the edge block is 13.8 cm × 6.3 cm, the total thickness is 4 cm; the chamfer height of the upper part of the main locking block and the edge block is both 1 cm, and the inclination angle is 45°; taking the example of 2 × 2 main locking blocks with 8 edge blocks, the hole rate of the splicing unit can reach 31.2%.

[0035] When multiple main locking blocks are assembled, the locking plugs of the main locking blocks fit into the locking grooves, forming a single-sided limit in the X-axis direction. The locking protrusions on two adjacent locking plugs cooperate to form a single-sided limit in the Y-axis direction, effectively interlocking the four main locking blocks. Furthermore, the locking protrusions on the four adjacent locking plugs cooperate to form through-holes for planting grass, ensuring that the closest planting holes are spaced approximately the same distance apart, ensuring that grass seedlings evenly cover the interlocking blocks.

[0036] The design of the splicing structure employed in this application can form planting holes with uniform spacing, effectively ensuring planting coverage while also providing strong interlocking strength and good stability. The small contact area between adjacent main locking blocks facilitates replacement of damaged main locking blocks, effectively improving construction convenience and maintenance efficiency.

[0037] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
