RAINWATER INFILTRATION TYPE ENVIRONMENTAL BLOCK OF PAVED ROAD SIDE DITCH CONSTRUCTION METHOD

摘要

PURPOSE: A rainwater infiltration type environmental block of a paved road side ditch construction method is provided to improve the appearance of a road by forming a U-shaped side ditch and to form a foundation for recycling rainwater by storing infiltrated water under the ground through an environmental block as ground water. CONSTITUTION: A rainwater infiltration type environmental block of a paved road side ditch construction method comprises: forming a valley(2) on the edge of a paved road(1) by pit-excavation, then leveling the bottom evenly; forming a bottom infiltration layer by covering the bottom of the valley with big gravel(3) at a thickness of 12-18 centimeters, small gravel(4) at a thickness of 8-12 centimeters and sand(5) at a thickness of 5 centimeters in order; paving an environmental block(6) on the bottom infiltration layer along the valley; fill up the environmental block with soil, then hardening; and scattering with seeds of herbaceous plants.
