3, the strength layer 110 and the permeable layer 120 of the permeable sidewalk block 100 according to the present embodiment are formed to have a constant thickness, 100), and is a component that maintains permeability and bending strength.

The strength layer 110 secures the bending strength of the sidewall block 100 according to the present embodiment, and is formed as an impermeable layer so that the strength is excellent. Therefore, the strength layer 110 is composed of only cement and sand, and is the lowest layer of the sidewall 100 according to the present embodiment.

Next, the permeable layer 120 is formed between the strength layer 110 and the water permeable fine layer 130 as shown in FIG. 3, and is excellent in water permeability. Therefore, the permeable layer 120 may be composed of cement, sand, and gravel, and may have a structure in which the proportion of the gravels increases from the lower layer to the upper layer.

3, a drainage hole 150 is further formed in the strength layer 110 and the permeable layer 120. [ The drain hole 150 is formed by penetrating the strength layer 110 and the permeable layer 120 from the lower side to the upper side and the upper end thereof is formed up to the interface with the water permeable fine layer 130. The water absorbed through the water permeable fine layer 130 and the water permeable layer 120 by the drain hole 150 can be drained downward through the impermeable strength layer 110.

As shown in FIGS. 2 and 3, a plurality of the drain holes 150 may be formed at a predetermined interval, and the size and number of the drain holes 150 may be variously changed.

Next, as shown in FIG. 3, the permeable fine layer 130 is formed to have a certain thickness on the permeable layer 110 and is permeable. Therefore, in the present embodiment, the permeable fine layer 130 is composed of particles for forming voids and cement, and the particles for forming voids have a diameter of about 0.5 to 4 mm and are preferably formed of dolomite or calcined stone.
