[0012] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application will be further described in detail below in combination with specific embodiments and with reference to the drawings.

[0013] Specific embodiments: in combination with Figs. 1-2As shown, a slope protection brick comprises a brick body 1, the two sides of the brick body 1 in the width direction are provided with clamping blocks 2, the two sides of the clamping blocks 2 in the length direction of the brick body 1 are provided with side protrusions 21, the side protrusions 21 are located on the side of the clamping blocks 2 away from the brick body 1, the cross section of the side protrusions 21 is a right trapezoid, the side of the side protrusions 21 close to the brick body 1 gradually moves away from the symmetry plane in the length direction of the brick body 1 from the close to the far side of the brick body 1, the side of the clamping blocks 2 close to the brick body 1 is provided with clamping grooves 22 on the two sides in the length direction of the brick body 1, the clamping grooves 22 are matched with the side protrusions 21, the side of the clamping blocks 2 away from the brick body 1 is provided with a recess 23 with a cross section of an isosceles triangle, the recess 23 is symmetrical about the symmetry plane in the length direction of the brick body 1, the brick body 1 is provided with inclined surfaces 5 on the two sides of the clamping blocks 2, the inclined surfaces 5 are matched with one side of the recess 23 (i.e. the side of the isosceles triangle on which one side of the isosceles triangle is located), the inclined surfaces 5 gradually move away from the symmetry plane in the width direction of the brick body 1 from the close to the far side of the clamping blocks 2. The distance between the outer sides of the two side protrusions 21 on the same clamping block 2 is a, the distance between the bottom of the clamping groove 22 (i.e. the side of the clamping groove 22 close to the symmetry plane in the length direction of the brick body 1) and the nearest end in the length direction of the brick body 1 is b, the height of the right trapezoidal cross section of the side protrusion 21 is c, and the length of the brick body 1 is d, then a=2b, a+2b-2c=d. When paving, the clamping grooves 22 of the clamping blocks 2 on the two sides of one of the slope protection bricks are clamped with the side protrusions 21 on the two sides of the other two slope protection bricks, and the recess 23 on the clamping block 2 of the one slope protection brick is matched with the inclined surfaces 5 on the two sides of the other two slope protection bricks, so that the adjacent slope protection bricks can be interlocked and fitted. Fig. 2 As shown, the clamping grooves 22 on the two sides of the clamping blocks 2 on one of the slope protection bricks (hereinafter referred to as the first one) are clamped with the side protrusions 21 on the two sides of the other two slope protection bricks, and the recess 23 on the clamping block 2 of the first slope protection brick is matched with the inclined surfaces 5 on the two sides of the other two slope protection bricks, so that the adjacent slope protection bricks can be interlocked and fitted. Because the length of the clamping block 2 is relatively large (in the prior art, the distance from the hook to the end of the brick body in the length direction is about half of the length of the clamping block 2 in the present application, when the length of the brick body 1 is the same), the maximum tensile force that can be borne in the length direction is relatively high.

[0014] Further, one end of the brick body 1 in the length direction is provided with a buckling block 4, the buckling block 4 is in the shape of a cuboid, the other end of the brick body 1 in the length direction is provided with a buckling groove 7 matched with the buckling block 4. Because the buckling block 4 is in the shape of a cuboid, the dimensions of the buckling block 4 and the parts of the brick body 1 on the two sides of the buckling block 4 in the up-down direction can be equal or close (if the dimension of one of the three is too small, the strength is relatively low). In combination with the fact that the length of the buckling block 4 is relatively large, the maximum tensile force that can be borne in the length direction is relatively high. Fig. 2 Fig. 2 ​As shown, when the engaging block 4 on one of the slope protection bricks is inserted into the engaging groove 7 on another of the slope protection bricks, the two slope protection bricks are more difficult to move away from each other in the length direction due to the use (i.e. the cooperation of the groove 23 and the inclined surface 5) of the other slope protection bricks (hereinafter referred to as the third one) adjacent to the two slope protection bricks in the up-down direction of the two slope protection bricks, and the third slope protection brick is more difficult to move away from the two slope protection bricks in the width direction under the action of the clamping block 2, and the interlocking and fitting of the adjacent slope protection bricks are more reliable and firm.

[0015] Further, the four edges of the brick body 1 in the thickness direction are all provided with the chamfer 3, and the edges are not easy to break.

[0016] Further, the brick body 1 is further provided with the hollow part 6 penetrating through the two sides in the thickness direction, which not only saves the material, but also reduces the weight of the slope protection brick.

[0017] The above is only the preferred embodiment of the present application, and does not limit the present application, and any simple modification, change and equivalent structure change of the above embodiment according to the technical essence of the present application are all within the protection scope of the technical scheme of the present application.
