摘要： PROBLEM TO BE SOLVED: To reduce the execution cost and to improve shock damping performance by fitting buffers allowing the sliding of ropes, holding the end sections of the ropes with individual buffers, and individually setting the holding force of the ropes. SOLUTION: This shock absorbing protective fence is constituted of supports 20 erected on a slope 10, a plurality of ropes 30, 31, 32... horizontally stretched between the supports 20, and a net material 40 stretched between upper and lower ropes 30, 31, 32. Buffers 50 are provided on individual ropes 30, 31, 32..., and the holding force (sliding resistance) is individually set. When a falling stone collides with the net material 40, the shock is applied to the ropes 30, 31, 32... as tensile force. When the tensile force exceeds the holding force of the buffer 50, each rope starts sliding, and shock energy is damped by this sliding resistance. The ropes 30, 31, 32... can be reliably prevented from being released, and release dedicated stoppers can be omitted.

摘要： PROBLEM TO BE SOLVED: To provide an impact-absorption technique capable of greatly improving damping effect of impulse energy, and stopping a material body having kinetic energy of 4000 KJ or more. SOLUTION: Elastic posts 20 eleastically deformable across the entire length are erected at predetermined intervals. Loop net 30 is attached between the posts 20. Impact energy is received as compressive force in the axial direction of the elastic post 20 while receiving impact so as to enfold the impact with the net 30 to attenuate the energy by an elastic deformation across the entire length of the elastic post 20.
