Through the water channel 312 opened inside the porous cement 311, when rainwater is discharged outward through the water guide horizontal hole 327, it is discharged inside the water channel 312. At the same time, since the porous cement 311 is set in an S shape, the impact of falling water flow can be avoided. When the water flow enters the porous cement 311, it will be absorbed by the porous cement 311 and guided to the inside of the soil block 313, assisting the growth of plants inside the soil covering groove 317 opened on the surface of the outer waterproof layer 314, and also avoiding the excessive flow rate to carry away soil and water loss.
