Description
본 발명은 교각의 안전을 위한 차량 충돌방지장치에 관한 것으로, 더욱 상세하게는 교각을 향해 돌진하는 차량으로부터 교각을 안전하게 보호하는데 이용하는 교각의 안전을 위한 차량 충돌방지장치에 관한 것이다.The present invention relates to a vehicle collision prevention device for the safety of the pier, and more particularly to a vehicle collision prevention device for the safety of the piers used to safely protect the pier from the vehicle rushing toward the pier.
일반적으로 고가도로를 지지하는 교각은 도로 위에 세워져 있기 때문에 항상 차량충돌로부터 노출되어 있다. 따라서 종래에는 교각을 보호하기 위해 첨부도면 도1에 도시된 바와 같이 교각(10) 앞에 환봉형태의 지주(12a)를 세우고 폐타이어(12)를 지주(12a)에 끼우면서 다단으로 적층하여 교각(10)을 향해 돌진하는 차량(14)을 저지하여 교각(10)을 보호하고 있었다.In general, bridges supporting overpasses are built on the road and are always exposed from vehicle crashes. Therefore, in order to protect the pier in the prior art, as shown in the accompanying drawings, as shown in FIG. 1, the pillar-shaped support 12a is erected in front of the pier 10, and the waste tires 12 are inserted into the support 12a and stacked in multiple stages. The pier 10 was protected by blocking the vehicle 14 rushing toward 10).
그러나, 종래 이와 같은 교각보호시설은 폐타이어(12)를 지지하기 위한 지주(12a)의 지지력이 부족하기 때문에 충격을 흡수하기도 전에 지주(12a)가 넘어지면서 차량(14)이 교각(10)에 부딪쳐 대형사고로 이어지는 문제점이 있었다.However, such a pier protection facility in the related art lacks the support force of the support 12a for supporting the waste tire 12, so that the support 14a falls over the bridge 10 before the support 12a falls even before the shock is absorbed. There was a problem leading to a large accident.
또한, 종래 교각보호시설은 탄성복원력을 갖는 단순한 완충구조로만 되어 있었기 때문에 차량 충돌시 충격에너지를 폐타이어(12)가 흡수하여 소멸하는 것이 아닌 폐타이어(12)가 충격에너지의 상당부분을 저장하고 있다가 압축한계지점에 이르러 탄성복원력에 의해 반력을 발생시켜 충돌 차량(14)을 다시 예상치 못한 방향으로 밀어내면서 2차 추돌사고를 발생시키는 위험이 있었다.In addition, since the conventional pier protection facility has only a simple buffer structure having elastic restoring force, the waste tire 12 stores a significant portion of the impact energy instead of being absorbed and destroyed by the waste tire 12 when the vehicle crashes. At the compression limit point, there was a risk of generating a secondary force by generating a reaction force by the elastic restoring force and pushing the crash vehicle 14 in an unexpected direction again.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 교각을 향해 돌진하는 차량의 충격에너지를 흡수하는 동안 지지물의 전도를 방지하여 충돌 차량과 교각을 동시에 보호할 수 있으며, 충격에너지를 흡수와 동시에 소멸하도록 하여 충돌 후 반력을 제거함으로써 반력에 의한 충돌 차량의 2차 추돌사고를 방지할 수 있는 교각의 안전을 위한 차량 충돌방지장치를 제공함에 있다.The present invention has been made to solve the above problems, the object is to prevent the fall of the support while absorbing the impact energy of the vehicle rushing toward the pier to protect the collision vehicle and the pier at the same time, the impact energy It is to provide a vehicle collision prevention device for the safety of the piers that can prevent the secondary collision of the collision vehicle by the reaction force by removing the reaction force after the collision by eliminating at the same time to absorb.
