Method and device for dirt intercepting permeable pavement

A method for implementing a dirt intercepting permeable pavement comprising:

• Step AA:
• producing an integrated prefabricated board with a plurality of toothed grooves in advance, directly laying a porous concrete material mainly composed of a plurality of crushed stones to be transported to a construction pavement, filling a base layer on the integrated prefabricated board with the porous concrete material, and then compacting the porous concrete material;
• Step AB:
• using natural gravel to lay a cushion, wherein a laying thickness is determined by a plurality of project requirements, laying a top of the cushion alternately with permeable gravel and natural gravel, wherein a separation distance is determined by the plurality of project requirements, and compacting the construction pavement multiple times, after the construction pavement is compacted multiple times, a top of a cushion layer forms a toothed groove structure;
• Step BB:
• using an integrated coulter to plow a certain thickness of the base layer out of a groove, and at the same time using a permeable paint or a fine sand to be padded from a feeding port to form a dirt interception trough;
• wherein step AB and step BB are performed in sequence, or step AA and step BB;
• determining an interval and depth of the dirt interception trough according to a plurality of requirements of a pervious pavement, the dirt interception trough reduces an infiltration rate of a water flow to a certain extent, and adjusting a plurality of different spacing requirements by changing a coulter group to meet a plurality of requirements of the water flow.
