Anti-blocking water-permeable passage

The invention relates to the technical field of drainage, in particular to an anti-blocking water-permeable passage. The anti-blocking water-permeable passage comprises a face brick layer, a water-permeable layer, a water storage layer and a base layer which are sequentially arranged from top to bottom, wherein the face brick layer comprises solid pavement bricks which are continuously spliced andwater-permeable channels which are arranged on the solid pavement bricks; each pavement brick is provided with one water-permeable channel, and the water-permeable channels vertically run through thepavement bricks; the water-permeable layer is made of water-permeable concrete with the same aggregate grade and the porosity of about 20%; the water storage layer is formed by compacting graded broken stone particles. Filter bags capable of being replaced in time and capable of filling the whole water-permeable channels are utilized, the problem that an existing water-permeable layer is blockedand a whole pavement needs
