RAIN WATER BOX OF TRAP-TYPE

PURPOSE: A trap-type gutter is provided to prevent a drain pipe from being blocked by filtering the foreign substances of rainwater and to treat a great deal of rainwater in a short time. CONSTITUTION: A trap-type gutter (100) comprises a first space part (110), a second space part (120), and a third space part (130). The first space part allows rainwater to flow into a rainwater inlet (111) from a road and filters the foreign substances of rainwater with a relatively small specific gravity. The second space part is separated from the first space part using a first partition (140) and filters the foreign substances of rainwater with a relatively large specific gravity. The third space part is separated from the second space part using a second partition (150) and discharges rainwater to a drain pipe through an outlet (133).
