To further increase the buffering efficiency, the buffering unit 151 of the first buffer band 150 and the buffering unit 161 of the buffering unit 161 of the second buffering band 160 may be configured differently to further increase the buffering efficiency. have.

As described above, according to the present invention, the support force of the support which is installed at a predetermined interval on the ground such as the soft ground around the dyke by using the support reinforcement frame and the buffer band can be further improved, as well as the vehicle. In the case of side impact on the shore, by cushioning the impact applied to the shore while the pleating portion of the buffer band is unfolded, it is possible to prevent the fall and rollover of the vehicle as well as to minimize the casualty accident.

In addition, the pleats of the first buffer band and the second buffer band located on the left and right sides are respectively different, thereby improving the buffer efficiency against the side impact of the vehicle, it is possible to prevent the fall and rollover of the vehicle, of course. Human accidents can be further minimized.

The present exemplary embodiment described above is not limited to the accompanying drawings, and various permutations, modifications, and changes can be made without departing from the spirit of the present invention. It will be obvious to him. For example, the strut reinforcement frame, the fixing frame, the connection bracket, the buffer band is not limited to the shape disclosed in the drawings, it can be changed according to the design conditions of the construction site.
