Detachable shock absorption facility equipped with guard rail {SHOCK ABSORPTION APPARATUS}

The present invention relates to a separate shock absorbing facility equipped with a guard rail, and in particular, to a separate shock absorbing facility equipped with a guard rail capable of effectively buffering a horizontal shock load caused by a vehicle or the like.

Vehicle protection safety facility is an accessory of the road regulated by the Road Law, and prevents a vehicle whose direction is wrong while driving from leaving the road or into an opposite lane, or prevents a vehicle from directly colliding with a structure, thereby preventing vehicle occupants and vehicles. , It refers to a facility installed to safely protect pedestrians or major facilities along the road.

The types of vehicle protection safety facilities include various vehicle protection fences, transition sections, end treatment facilities, shock absorption facilities, and shock absorption facilities (TMA) for attaching and detaching trucks.

Among them, the shock absorbing facility is installed in a place where there is a risk of a vehicle breaking out of the driving lane and colliding with a structure on the road due to the driver's negligence, and the function of the shock absorbing facility absorbs the shock energy of the vehicle to stop the vehicle. , It plays a role of correcting the direction and returning to the driving lane safely.

In addition, there are additional functions such as reducing the driving speed of the vehicle by easily grasping the location of the driver's dangerous object, or allowing the driver to take appropriate actions such as changing lanes.

The shock absorbing facility is usually installed in a place where there is a high risk of an accident among places where a collision between a facility and a vehicle is expected. It can be additionally installed in places where the risk of an accident is considered high according to the judgment of the road manager, in addition to the rigid protective fence or the end of the foundation of the soundproof wall, the front of the tollgate, the entrance to the tunnel and underpass.

These shock absorbing facilities have been developed and installed in various structures of the constitution.

However, since the number of members used in the shock absorbing facility is large, as well as very complex, the inefficiency of construction is accompanied by combining each component, and a large amount of time and economic loss occurs to restore it when a vehicle impact occurs. There was a problem.
