林木抗风折钢丝绳串联加固器的设计和应用

Design and Application of Forest Resisting Wind-Breakage Wire Rope Serial Reinforcement Device

为了降低林木风折率和预防安全事故的发生,设计一种由卡环、弹簧、卡板和钢丝绳组成的林木抗风折钢丝绳串联加固器。应用试验结果表明:1)树干风折率和枝条风折率为0.21%和1.07%,较对照(CK)分别降低了87.88%和72.56%;2)树干和枝条风折后在构件钢丝绳的拖负下悬挂在空中,不着地,不会立即造成安全事故,给险情处置争取了一定时间;3)制作简单,取材方便,安装简便。鉴于以上优势,建议将钢丝绳串联加固器在排状林木风折灾害预防中示范推广。

In order to decrease forest wind-breakage rate and prevent safety accidents,a kind of serial reinforcement device was designed,which was formed with the clasp,spring,clip and wire rope.The test result showed that:1)Trunk and branch wind-breakage rates were 0.21%and 1.07%,decreased 87.88%and 72.56%than CK separately;2)Trunks and branches were not fell,not occurred safety accidents immediately,which can win a certain amount of time to dangerous situation disposal;3)Simple to produce,convenient to take materials,easy to instal.Based on the above advantages,the serial reinforcement device should be demonstrated and promoted in wind-breakage disaster prevention of row pattern forest.
