Thereby connecting the individual slope protection bricks 41 together to jointly resist the river flushing. In the present embodiment, the connecting member 43 is a bolt 431 or a nut 432, and in other embodiments, the position of the slope protection brick 41 may be fixed by a self-locking nylon tie.

Specifically, the slope protection bricks 41 are arranged in rows along the slope of the slope body 1, each row of slope protection bricks 41 is arranged at intervals, and the slope protection bricks 41 in adjacent rows are arranged in a staggered manner, so that the oblique sides 411 of the two slope protection bricks 41 in the diagonal positions are abutted and connected and fixed through bolts 431. Four mutually spliced slope protection bricks 41 enclose a second planting groove 82 for accommodating vegetation. The slope protection bricks 41 are arranged at intervals and fixedly connected through the bolts 431, so that the stability of the slope protection layer 4 is guaranteed, the consumption of the slope protection bricks 41 is reduced, and the construction cost is reduced.

Referring to fig. 2, in order to improve stability of the slope protection layer 4, support members 42 are disposed between slope protection bricks 41 spaced apart from each other at a bottom layer, and the support members 42 may be formed by casting concrete.
