PURPOSE: An improved substructure of a permeable concrete with an improved permeation function is provided to install a permeable porous block for replacing lower part of basic floor, to install a sheet for ground sinking prevention which is a nonwoven type form or a woven type form in the upper and the lower side of the basic floor, and to prevent ground sinking and loss of permeation function according to long term inflow of rainwater. CONSTITUTION: An improved substructure of a permeable concrete with an improved permeation function comprises a filter layer(30) installed on an in ground, a permeable porous block(60) installed on the upper side of the filter layer, a woven type sheet for ground sinking prevention installed in the lower side of the permeable porous block, and a nonwoven type sheet(50) for ground sinking prevention installed in the upper side of the permeable porous block. |
