Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of side slope protection, and particularly relates to a protective brick and a combination of a plurality of protective bricks. BACKGROUND

[0002] Side slope protection is an important part of civil engineering and has great significance for preventing landslides, soil erosion and protecting the ecological environment. Traditional side slope protection methods use materials such as concrete and stones, which have high construction difficulty and cost, and obvious shortcomings in environmental protection and ecological restoration. In recent years, with the rise of the concept of ecological slope protection, side slope protection bricks have been widely used as a new type of protective material. However, the existing side slope protection bricks still have many problems in practical application:

[0003] 1. Insufficient interlocking performance: In the prior art, common highway engineering bricks are hexagonal bricks, which can be laid on highway slopes and planted with vegetation to prevent soil erosion and slope collapse and protect highway safety. However, these bricks are independent of each other and do not form effective connections, resulting in poor overall stability of the highway slope. In the event of natural disasters such as heavy rainfall and earthquakes, the bricks may loosen or even fall off, thereby rendering the side slope protection ineffective.

[0004] 2. Low construction efficiency and safety: For example, the utility model patent with the authorization announcement number CN217651707U, a water conservancy engineering ecological slope water storage device, includes a slope body and a water storage adjusting assembly for protection and water storage set on one side of the slope body, the slope body has a slope surface, and multiple arc-shaped shells are arranged on the side surfaces of the first brick body and the second brick body. The bottom end of the slope surface is provided with a U-shaped baffle for water storage protection of the slope body. The water storage device for the ecological slope of the water conservancy project can alleviate the impact of rapid river water level rise on the slope surface, thereby reducing the collapse of the slope protection. However, the side surfaces of the first brick body and the second brick body are provided with multiple connecting holes, and the connecting holes are connected by a clamping block. During installation, the bricks are first laid on the slope surface, and then the clamping block is clamped between the two connecting holes. The laying process is complicated, and if the clamping block is forgotten during the laying process, the connection between the two bricks may be reduced. Even if the clamping block is not forgotten during installation, it may still be shaken out of the connecting hole during an earthquake, thereby affecting the connection between the bricks. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a protective brick, which is clamped with adjacent protective bricks, limited by each other, has a close connection, and has a planting groove between the protective bricks, which can prevent soil erosion and greening.

[0006] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A protective brick, comprising a rectangular brick body, first and second clamping grooves are arranged on both sides of the brick body to form first, second and third convex parts on both sides of the brick body, a center line is perpendicular to the opening direction of the first and second clamping grooves, the first and second clamping grooves are symmetrical about the center line, the first and third convex parts are symmetrical about the center line, first clamping parts are arranged on the first, second and third convex parts on one side of the brick body, and second clamping parts corresponding to the first clamping parts are arranged at the ends of the first and second clamping grooves on the other side of the brick body.

[0008] Preferably, a third clamping part is arranged at one end of the brick body, and a fourth clamping part matched with the third clamping part is arranged at the other end of the brick body.

[0009] Preferably, the side walls of the first and second clamping grooves are inclined and parallel to the side away from the second convex part, and the first and third convex parts are provided with inclined surfaces at the ends away from the second convex part to enable the first or third convex part to be clamped into the first or third clamping groove.

[0011] Preferably, the third clamping part comprises a third inclined surface arranged at the bottom of the third clamping part, the fourth clamping part comprises a fourth inclined surface arranged at the top of the fourth clamping part, and the third and fourth inclined surfaces are matched and limited to each other.

[0012] Preferably, the second convex part is wedge-shaped and symmetrical about the center line.

[0013] Preferably, a planting groove is arranged on the brick body, the planting groove is rectangular and provided with a chamfer.

[0014] Preferably, a through groove is arranged at the bottom of the brick body, and the through groove is arranged along the length direction of the center line.

Further, the third clamping part is arranged at one end of the brick body, the fourth clamping part is arranged at the other end of the brick body, and the clamping of the third clamping part and the fourth clamping part realizes the interlocking of the two brick bodies in the left-right direction, so that the brick bodies can be closely connected after paving and are not easy to loosen, and the stability and safety of the connection of the brick bodies are enhanced. Meanwhile, the clamping form of the clamping groove and the protrusion arranged on the brick body simplifies the installation process and makes the paving work more efficient. Construction personnel do not need to use complex tools or additional fixing materials to fix the two adjacent brick bodies, and only need to splice the brick bodies in a predetermined manner.

[0017] The two side walls of the first clamping groove and the second clamping groove are inclined and parallel to the side away from the second protrusion, and when the multiple brick bodies are clamped, the locking between the two brick bodies above and below is more firm, so as to avoid the disengagement between the two brick bodies above and below due to external factors, and further increase the connectivity between the brick bodies.

[0019] Another purpose of the utility model is to provide a combination for a plurality of protective bricks, which has strong connectivity and can connect single brick bodies into a whole, thereby effectively improving the stability of the whole.

[0020] To achieve the above purpose, the utility model adopts the following technical scheme:

[0022] In the above technical solution, the first brick is connected to the second brick, and the third brick is connected to the fourth brick by setting a third and a fourth locking part. The first brick is connected to the third brick by locking the third protrusion of the first brick with the first locking part to the first slot of the third brick with the second locking part.
