A safety device for a sharp curve tunnel, of the present invention comprises: a plurality of impact absorbing rods each including, therein, two or more cylinders having a concentric shape and different diameters, wherein the top surface of the innermost cylinder is closed, and provided at predetermined intervals along the wall surface of a curved section in a tunnel; an air supply pipe for providing pressure air for adjusting the length of each of the plurality of impact absorbing rods by pushing up the cylinders included in the plurality of impact absorbing rods; a vehicle speed measurement device for measuring the moving speed of a vehicle at a front speed measurement point that is a predetermined distance away from the curved section; and a control unit for previously storing the safety speed information of the vehicle, comparing the measured moving speed with the safety speed, and adjusting the amount of air pressure delivered to the inside of the plurality of impact absorbing rods based on an excess amount of the moving speed when the moving speed exceeds the safety speed. Therefore, an accident caused by a collision between the vehicle and the inner wall of the tunnel in the curved section of the tunnel can be prevented, and when an accident occurs, the damage can be minimized.

    본 발명의 급커브 터널의 안전장치는 지름이 서로 다른 2이상의 동심원 형태의 원기둥들을 내부에 포함하되, 가장 안쪽에 위치한 원기둥의 상부면이 폐쇄되며, 터널 내 커브 구간의 벽면을 따라 소정 간격을 두고 설치된 다수의 충격 흡수봉들; 상기 다수의 충격 흡수봉들 내부에 포함된 원기둥들을 상부로 밀어 올려서 상기 다수의 충격 흡수봉들 각각의 길이를 조절하기 위한 압력공기를 제공하는 공기공급관; 상기 커브 구간으로부터 소정거리 떨어진 전방의 속도측정지점에서 차량의 이동속도를 측정하는 차량속도 측정장치; 및 차량의 안전속도 정보를 미리 저장하고, 상기 측정된 이동속도와 상기 안전속도를 비교하여 상기 이동속도가 상기 안전속도를 초과하는 경우 그 초과량에 기초하여 상기 다수의 흡수봉들 내부로 전달되는 압력공기의 양을 조절하는 제어부를 포함하여, 터널의 커브 구간에서 차량과 터널 내벽과의 충돌에 의한 사고를 예방하고, 사고 발생시 그 피해를 최소화할 수 있는 장점이 있다.
