Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to an ecological slope protection brick. Background Art

[0002] Slope protection refers to the reinforcement and protection of slopes in highway, railway, mining, water conservancy and other projects to prevent safety accidents such as slope collapse and landslide, and to ensure the safe and stable operation of the project. Slope protection bricks are often used for slope protection. Slope protection bricks can improve the stability and anti-erosion ability of the slope. Since slope protection bricks are beneficial to environmental protection and ecological balance, they are also called ecological slope protection bricks.

[0003] When laying slope protection bricks, adjacent slope protection bricks are connected by plugging or overlapping, and the connection stability is poor. When encountering strong rain or river erosion, the connection between adjacent slope protection bricks is easy to collapse and lose the connection ability, resulting in poor protection of the slope. Summary of the invention

[0004] The utility model solves the problem of poor connection between slope protection bricks and provides an ecological slope protection brick, which can prevent the slope protection bricks from losing connection when being washed by strong rain or river water, thereby improving the protection effect of the slope.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] An ecological slope protection brick comprises a plurality of brick bodies, each side of the brick body is provided with a dovetail groove sunken into the brick body, and the two ends of each dovetail groove respectively penetrate the upper and lower surfaces of the brick body; the side surfaces of the plurality of brick bodies are in contact with each other, and two adjacent brick bodies are connected via a connecting piece, and the connecting piece comprises a connecting block and a V-shaped plate, and the connecting block is a block-shaped body formed by connecting the narrow ends of two isosceles trapezoidal blocks, and the inclined surfaces on the same side of the two isosceles trapezoidal blocks form a V-shaped groove, and a corresponding V-shaped plate is arranged in the V-shaped groove, and a driving piece for driving the two V-shaped plates to move in opposite directions is arranged on the connecting block; the dovetail groove openings on the two adjacent brick bodies are opposite to each other, and the two isosceles trapezoidal blocks of the connecting piece are respectively located in two dovetail grooves opposite to each other with the two openings, and the inclined surfaces on the same side of the two openings opposite to the dovetail grooves are pressed tightly by the V-shaped plate on the same side of the connecting piece.

[0007] Furthermore, a planting hole is provided in the middle of the brick body.

[0008] Furthermore, the wide end of the isosceles trapezoidal block corresponds to the sum of the thickness of the two V-shaped plates and the inner bottom width of the dovetail groove; the narrow end of the isosceles trapezoidal block corresponds to the sum of the thickness of the two V-shaped plates and the opening width of the dovetail groove.

[0009] Furthermore, the distance between the upper and lower sides of the isosceles trapezoidal block corresponds to the distance between the upper and lower ends of the dovetail groove.

[0010] Furthermore, the driving member includes a threaded hole and a connecting rod. A threaded hole is provided at the connection between the two isosceles trapezoidal blocks of the connecting block. Connecting rods are connected to the opposite surfaces of the two V-shaped plates on the same connecting member. The free end of each connecting rod passes through the connecting block and extends into the threaded hole. Bolts are threadedly connected in the threaded holes on the upper sides of the free ends of the two connecting rods, and the tail ends of the bolts are connected to hemispheres.

[0011] Furthermore, when the two V-shaped plates on the connecting piece contact the V-shaped groove on the same side, there is a distance between the free ends of the two connecting rods; when the two V-shaped plates on the connecting piece contact the V-shaped groove on the same side and the free ends of the two connecting rods contact the lower part of the spherical surface of the hemisphere, there is a distance from the head of the bolt to the top surface of the connecting block.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model connects two adjacent brick bodies through a connecting piece, and two isosceles trapezoidal blocks on the connecting piece limit the dovetail grooves of the two brick bodies, so that the two brick bodies will not separate in the horizontal direction, thereby enhancing the connectivity of the two brick bodies, and the inclined surfaces on the same side of the two dovetail grooves with opposite openings are pressed tightly by the V-shaped plate on the same side of the connecting piece, so that the two contacting brick bodies will not separate in the vertical direction, thereby further enhancing the connectivity of the two brick bodies, and the two brick bodies will not be separated due to strong rain or river scouring.

[0014] The utility model rotates the bolt so that the V-shaped plate on the connecting piece where the bolt is located no longer presses against the inclined surface of the dovetail groove, so the connecting piece can be conveniently taken out and the damaged brick body can be conveniently replaced.

The connecting block 3 is provided with a driving member for driving the two V-shaped plates 4 to move in opposite directions; the dovetail grooves 2 on the two adjacent brick bodies 1 have openings facing each other, and the two isosceles trapezoidal blocks of the connecting member are respectively located in two dovetail grooves 2 with two openings facing each other, and the inclined surfaces on the same side of the two openings facing the dovetail grooves 2 are pressed tightly by the V-shaped plate 4 on the same side of the connecting member.

[0025] A planting hole 6 is provided in the middle of the brick body 1, and the planting hole 6 is a round hole.

[0026] The wide end of the isosceles trapezoidal block matches the sum of the thickness of the two V-shaped plates 4 and the inner bottom width of the dovetail groove 2; the narrow end of the isosceles trapezoidal block matches the sum of the thickness of the two V-shaped plates 4 and the opening width of the dovetail groove 2.

[0027] The distance between the upper and lower sides of the isosceles trapezoidal block corresponds to the distance between the upper and lower ends of the dovetail groove 2.

[0028] The driving member includes a threaded hole 7 and a connecting rod 8. The threaded hole 7 is provided at the connection between the two isosceles trapezoidal blocks of the connecting block 3. The threaded hole 7 passes through the upper and lower surfaces of the connecting block 3. The two V-shaped plates 4 on the same connecting member are connected with connecting rods 8 on opposite surfaces. The connecting rod is a round rod. The free end of each connecting rod 8 passes through the connecting block 3 and extends into the threaded hole 7. The connecting block is provided with a through hole 11 for the connecting rod 8 to slide through. The threaded holes 7 on the upper sides of the free ends of the two connecting rods 8 are threadedly connected with bolts 10. The tail end of the bolt 10 is connected with a hemisphere 9. The diameter of the hemisphere 9 is the same as the rod diameter of the bolt 10.
