AVALANCHE PREVENTION FACILITY
PROBLEM TO BE SOLVED: To provide an avalanche prevention facility for making avalanche prevention fences evenly support a snow load by distributing the load into the fences while preventing snow from falling out through open space between fences adjacent to each other, by using a simple method.SOLUTION: An avalanche prevention facility comprises: a plurality of avalanche prevention fences 10 provided on a slope G so as to erect in a horizontal line; and a rope net 20 for blocking open space 15 formed between avalanche prevention fences 10 adjacent to each other. The rope net 20 has an endless loop structure made of a rope material whose both ends are separably connected to each other. A plurality of mooring tools 30 are provided on fences' main columns 11, 11 of adjacent to each other. The rope net 20 blocks the open space 15 by being made to be in a net shape by slidably mooring part of the rope net 20 in the main columns 11 of the end parts through the plurality of mooring tools 30 so as to be capable of distributing and transmitting a snow load acting on part of the rope net 20 over the whole length of the rope.
【課題】簡易な手法によって隣り合う雪崩予防柵の開放空間を通じた雪の抜け落ちを防止しつつ、積雪荷重を雪崩予防柵に分散して均一に支持させる雪崩予防施設を提供することこと。【解決手段】斜面Ｇに横列に立設した複数の雪崩防止柵１０と、隣り合う雪崩防止柵１０の間に形成した開放空間１５を封鎖するロープネット２０とを具備し、ロープネット２０がロープ材の両端を分離可能に接続した無端ループ構造であり、隣り合う端部の主柱１１，１１に複数の係留具３０を設け、ロープネット２０の一部に作用した積雪荷重をロープの全長に亘って分散伝達し得るように、複数の係留具３０を介してロープネット２０の一部を端部の主柱１１に摺動自在に係留して開放空間１５をネット状のロープネット２０で封鎖する。【選択図】図２
