Porous concrete pavement structure

The utility model relates to the technical field of road engineering, in particular to a porous concrete pavement structure. According to the technical scheme, the structure comprises a stable base layer, a cement pavement is laid on the upper side of the stable base layer and inclines towards one side of a mountain, and a plurality of evenly-distributed inflow through holes are formed in the low-lying position of the side, close to the mountain, of the cement pavement; the lower sides of the inflow through holes are jointly communicated with a collecting shell, and one side of the collecting shell is communicated with a drainage pipe for draining water in the collecting shell. Rainwater flows into the collecting groove, flows into the flowing inner cavity through the flowing-in through hole in the bottom of the collecting groove and is drained through the drainage pipe, so that the rainwater on the inwards inclined road surface of the curved road in the mountainous area is drained, and accumulation of the ra
