Alternatively, a road wall installed on the side of a road, such as a railing of a bridge narrower than the width of a connecting road, is often damaged by an automobile collision. Therefore, in order to reduce the damage caused by the contact or collision on the road walls, a buffer barrier is installed on the front of the road walls. Since the shock-absorbing barrier is required to have a function of protecting the road wall, the weight of the shock-absorbing barrier itself must be large so as not to move easily due to a collision or to absorb the kinetic energy of the car in collision.
It is required that the amount of deformation or the permissible amount of movement upon receiving a collision is large. In addition, it is required to reduce as much as possible the impact on the automobile that has contacted or collided with the buffer barrier. Conventionally, as a buffer barrier which satisfies such demands, old tires, sand bags, old barrels or drums brewed with wine, filled with water, and the like have been adopted and placed on the front of a road wall.

った。However, the conventional buffer barrier in which old tires and sand bags are arranged has a poor appearance, and the amount of deformation absorbed by a collision is not large, so that the amount of energy absorbed there is small. Although the vehicle did not collide with the road wall, the collision with the shock-absorbing barrier caused serious damage to the vehicle. In addition, wooden barrels and drums filled with water will be destroyed or deformed instantaneously, so the amount of energy absorbed will be small, and after the car collides with the impact barrier, it will further advance and collide with the road wall was there.

A sand container is filled with sand and water to form a weight body, and a large number of the weight bodies are housed inside the housing box. The sand container is a PET bottle, and is housed in a housing box with their sides close to each other. Further, the inside of the storage box is vertically divided into a plurality of sections by a partition plate, and a weight body is supported for each of the sections. Further, the housing box is configured by an annular body formed by joining plate members having joining edges formed on two opposing sides, and an opening of the annular body is covered with a bottom plate and a top plate and closed.

って環状体が所要の平面形状となる。Since the weight is filled with both sand and water, a weight having a higher specific gravity than that of sand alone or water alone is formed, and absorbs a large amount of energy when deformed. The weights are also substantially cylindrical, and when aligned in a storage box, a substantially rectangular gap is formed between adjacent weights. The gap absorbs the energy of the collision when the vehicle collides, with the filling in the sand container moving into the gap. In addition, the movement of the filler is quickly performed by using the gap. If the sand container forming the weight is a PET bottle, the sand container is easily destroyed in the event of a collision despite the weather-resistant material, and the filler is discharged into the gap. In addition, if the weights are supported in multiple stages in the storage box, gaps are formed in the upper, lower, left, and right sides of the weights, so that the space to which the packing material moves when the weights break is large.
Furthermore, if the annular body that forms the storage box is formed of a plate member that is joined at the joining edge, the annular body has a required planar shape by appropriately bending the plate member.

い。The weight body 20 is constituted by a sand container 21 and a filler 22. Here, as the sand container 21, an empty bottle of a plastic bottle having a capacity of 1.5 liters, which is generally used for marketing drinking water and soft drinks, is diverted. Here, the used PET bottle has a diameter of about 9.5
cm and a height of about 30 cm, and has a roughly cylindrical shape, and a lid is detachably screwed to the top. As the filler 22, 2.4 kg of river sand having a specific gravity of 1.60 and 0.7 liter, that is, 0.7 kg of water are used. Thus, the total weight of the filling 22 is about 3.1 kg, and a larger weight can be obtained as compared with the case where the filling 22 is water alone or sand alone. In the practice of the present invention, it is not essential that the sand is the river sand, and it is sufficient that the sand is iron powder or other particles having a large specific gravity. Further, the shape of the sand particles is preferably not spherical, but has corners, because it has high deformation resistance.

さい。Since the shock absorbing barrier 10 is constructed as described above, when the vehicle collides with the shock absorbing barrier 10, the shock absorbing barrier 1
0 is deformed without moving because it has a large weight obtained by the weight body 20. First, the wall surface of the annular body 31 having little strength is torn, then the weight body 20 is torn, and the filler is rapidly pushed into the gap 38. Then, the adjacent weight bodies 20 are successively destroyed with a slight time difference, and the filler absorbs the collision energy and moves in the traveling direction of the vehicle. The kinetic energy of the crashed vehicle is thus consumed and the vehicle is stopped before it reaches the road wall. Also, the impact received by the vehicle is smaller than when it collides with a solid road wall such as concrete.
