BLOCK PURIFY THE EARLY RAIN FOR BOTH BOUNDARY

摘要

PURPOSE: An initial rain purification block with a boundary indicating function is provided to quickly remove initial rainwater and debris from a road surface and prevent the blockage of sewage systems. CONSTITUTION: An initial rain purification block with a boundary indicating function comprises a body(10), an inlet hole(12), and a permeation hole(13). The body comprises a catchment portion(11) inside thereof. The inlet hole and the permeation hole are formed on the opposite sides of the body so that initial rainwater and debris flowing along a road surface are purified by penetrating into the underlayer of the road surface via the catchment portion.
