Abstract

It becomes more and more important to develop various infiltration facilities for healthy water cycle and reduction of urban storm water runoff. In this study, a infiltration facility by utilizing tree box was developed. The developed facility is capable of reducing storm water road runoff, improving urban water cycle, and performing other sustainable and environmental functions. Because the facility can be manufactured to a smaller size than an existing runoff reduction facility, it can be installed at various road types of not only existing urban areas, but new developed areas. If the facility is applied to four-lane roadways, it is expected to reduce 65% of rainfall runoff discharge. Urban flood control improvement can be accomplished by a wide application of the developed technique.

우수유출저감과 건전한 도시 물순환 환경의 구축을 위하여 다양한 침투시설들의 개발 및 적용이 점점 중요해지고 있다. 본 연구에서는 도시에서 가로수목공간으로 사용되는 식재박스를 활용하여, 우수유출의 저감, 도시내 물순환 체계 개선 및 친환경적인 기능을 수행할 수 있는 침투시설을 개발하였다. 개발된 시설은 작은 규모로도 설치할 수 있어 광로, 대로, 중로, 소로 및 보행도로나 좁은 공간의 구분없이 설치가 가능하여, 기존 도시 및 신도시 등에 광범위하게 적용할 수 있다. 개발된 기술을 4차로에 적용할 경우 식수대의 설치간격을 6m미만으로 유지한다면, 98%의 호우사상에 대하여 우수의 유출을 65% 이상 저감할 수 있는 것으로 나타났다. 본 연구에서 개발된 가로수목공간 조성기술 적용을 통하여, 우수유출 저감에 따른 치수효과와 더불어 녹색도시의 구현이 가능할 것으로 기대된다.
