The present invention relates to a water permeable block including a sidewalk block installed on the ground and a protective frame including an internal receiving space wherein the sidewalk block is seated, walls covering the lateral part of the sidewalk block, and a bottom plate on which the underside of the sidewalk block is seated. The wall includes a fixed plate adhering to a lateral surface of the sidewalk block; an engaging plate formed at a predetermined distance from the fixed plate in an outer side of the fixed plate; and a supporting piece interposed between the fixed plate and the engaging plate to connect them to each other. A water permeable space unit with open top and underside is formed between the fixed plate and the engaging plate. Accordingly, the present invention is characterized by a fact that rainwater is permeable into the ground space via the permeable space units. |
