Description

도로용 중앙분리대 설치구조{Median Strip Structure}Median Strip Structure}

본 고안은 도로용 중앙분리대 설치구조에 관한 것으로, 더욱 상세하게는 도로의 중앙에 설치되어 충돌 차량으로부터 가해지는 충격을 흡수하고 가드레일의 변형을 방지하며, 맞은편 도로에서 발생된 소음을 차단하도록 한 도로용 중앙분리대 설치구조에 관한 것이다.The present invention relates to a structure for installing a central separator for roads, and more particularly, to absorb shocks from a crash vehicle, prevent deformation of guard rails, and block noise generated on opposite roads. It relates to a road divider installation structure.

일반적으로 도로의 중앙에는 중앙분리대를 설치하여 주행 차량이 중앙선을 넘지 못하도록 하고 있으며, 교통사고시 맞은편 차량과의 정면충돌을 방지하여 대형인명 피해를 줄일 수 있도록 되어 있다.In general, the central divider is installed at the center of the road so that the traveling vehicle does not cross the center line, and in the event of a traffic accident, the frontal collision with the vehicle opposite to prevent large casualties.
