[0003] Highway slope protection bricks are important traffic safety facilities. They play a key role in preventing and reducing road accidents. They not only protect the integrity of the slope, but also enhance the safety awareness of drivers and reduce the damage caused by accidents. However, the existing slope protection bricks cannot effectively prevent the grass seeds, soil and fertilizer inside the slope protection bricks. The grass seeds planted inside the slope protection bricks will be washed out under the action of water flow on rainy days, resulting in the inability of the grass seeds inside the slope protection bricks to survive and being lost under the action of water power, thus unable to perfectly protect the integrity of the slope. Therefore, it is necessary to solve and optimize the above problems. Summary of the Utility Model
