It is. That is, the method for preventing the collapse of a rockfall protection structure according to the present invention is to fix a lower plate to the upper surface of an existing rockfall protection structure, and to install springs on the mountain side edges of the upper surface of the lower plate and on the valley side edges. By fixing the hinges and removably attaching the hinges to the edge of the valley formed on the lower surface of the upper plate, the upper plate is tilted above the lower plate via the spring so as to be lower on the valley side. The rock fall protection structure is arranged so that rocks, earth and sand, etc. above the rock fall protection structure fall little by little onto the upper plate, and these rocks, earth and sand, etc. fall from the upper plate to the valley side of the rock fall protection structure. What are the characteristics?

When rocks, sand, etc. of the rock fall protection structure are dropped little by little onto the upper plate, the upper plate will rotate about the hinge and move downward against the force of the spring due to the weight of the rocks, sand, etc. Rotate. In this way, since the upper plate rotates downward while contracting the spring, the impact of the button on the rockfall protection structure due to falling rocks, earth and sand, etc., is significantly reduced. Next, the upper plate rotates upward due to the reaction of the spring, and this combined with the fact that the upper plate is sloped toward the valley side or lower, causes rocks, dirt, etc. on the upper plate to fall from the upper plate. Falling into the valley side of the protective structure.

い。As described above, rocks, earth, etc. above the rockfall protection structure are removed until there is no risk of rockfall, earth and sand collapse, etc., but after the removal work of rocks, earth, etc. in one place is completed, The upper and lower plates are moved laterally one after another to remove rocks, dirt, etc. from other locations one after another. Hey,
When removing rocks, dirt, etc. near the inside edge of the top plate, cut the spring to lower the height of the spring and lower the top plate so that the rocks, dirt, etc. fall onto the top plate. You may also do so.
次に、本発明の実施例を添付図面に従って説明する。 Next, embodiments of the present invention will be described with reference to the accompanying drawings.

望ましい。When fixing the lower plate 2 to the top surface of the rockfall protection structure 1, -
For example, one end of the fixing rod 3.3, which is driven into the soil near the mountain side (the left side in FIG. 1) of the rockfall protection structure 1, is welded to the mountain side end of the lower plate 2. As an example, the angle between each fixed rod 3 and the mountain side wall 4 of the rockfall protection structure 1 is about 60'. A spring 5 is fixed to the peak side line on the upper surface of the lower plate 2, a hinge 6 is fixed to the valley side (right side in FIG. 1) edge, and the hinge 6 is opened on the lower surface of the upper plate 7, such as an iron plate. By detachably attaching it to the edge, the upper plate 7 is arranged above the lower plate 2 via the spring 5 in a state where it is inclined so that the valley side is lower. In this state, the rocks above the rockfall protection structure 1,
Earth and sand, etc. 8 are dropped little by little onto the upper plate 7 by small explosions, etc., and these rocks, sand, etc. 8 are caused to fall from the upper plate 7 to the valley side of the rock fall protection structure 1. Hey, rocks, dirt, etc. in one place8
When the removal work is completed, the upper plate 7 and the lower plate 2 are moved laterally separately to remove rocks, earth, etc. 8 from adjacent locations. In this case, the upper plate 7 is moved sideways to the lower plate 2. When moving the upper plate laterally, an L-shaped member 9 is placed near the hinge 6 on the upper surface of the lower plate 2, and the hinge 6 is moved by sliding the upper plate 7 while being supported by the bent member 9. It is desirable to protect it.

落下する。(Effect of the invention) In the present invention, rocks above the existing rock fall protection structure,
By removing the earth and sand in advance, subsequent rockfalls, earth and sand collapse, etc. can be reliably prevented, and the collapse of the rockfall protection structure can therefore be prevented. In addition, as mentioned above, due to the action of the spring between the upper plate and the lower plate, the impact on the rockfall protection structure due to falling rocks, earth, etc. is significantly alleviated and damage to the structure is prevented, and the reaction of the spring and the upper Rocks, dirt, etc. that fall onto the upper plate due to the slope of the plate will surely fall to the valley side of the rockfall protection structure.
