PROTECTIVE NET, CONSTRUCTION METHOD OF THE SAME, AND METHOD OF ABSORBING KINETIC ENERGY OF FALL

PROBLEM TO BE SOLVED: To provide a protective net which is excellent in a kinetic energy absorbing action, is excellent in transportability and workability, and is executable at a low cost, its construction method, and a method of absorbing kinetic energy of a fall.SOLUTION: The protective net includes: a spreading net-like body 11 spread on a slope S; and fixing means 20 for fixing the spreading net-like body 11 to the slope S so as to form an opening 12 for introducing a fall falling along the slope S between a mountain side end of the spreading net-like body 11 and the slope S and to form a storage part for storing the fall R introduced from the opening 12 between the spreading net-like body 11 and the slope S. The spreading net-like body 11 comprises two or more kinds of net-like bodies, and on at least the mountain side part of the spreading net-like body 11, a buffer wire net 14 composed of a coil wire net for which loops are engaged with each other and a plurality of coils 13 are connected in parallel is provided.
