Hard road construction method for natural groundwater recharge

摘要

A hard road construction method for natural groundwater recharge. A flattened soil surface (1) is bored to an underground shallow sand belt water storage layer (12), holes (2) are filled with sand, rod-shaped tools (4) are inserted into the holes (2) filled with sand, concrete is poured to form a concrete foundation layer (5) having a flat surface, the rod-shaped tools (4) are removed, the holes (2) continue to be filled with sand up to the plane of the concrete foundation layer (5), sand laid on the concrete foundation layer (5) is compacted, and road bricks (7) are directly arranged on the sand surface, without being adhered, to form a hard road. Rain and snow water on the hard road rapidly and naturally recharges to the underground shallow sand belt water storage layer (12) through the holes (2) via road brick gaps (6), then slowly penetrates to an underground deep sand belt water storage layer (14).
