 高危边sns柔性防护网作用原理上类似于喷锚和土钉墙等面层护坡体系,但因其柔性特征能使系统将局部集中荷载向四周均匀传递以充分发挥整个系统的防护能力,即局部受载,整体作用,从而使系统能承受较大的荷载并降低单根锚杆的锚固力要求。我国公司多数紧贴陡坡、峭壁,部分路堑坡体处于强—中风化带中,裂缝较发育,岩体破碎,抗风化能力差。经过长年运营,在风化应力作用及雨水的侵蚀下,时常引起落石、塌滑,造成堵车、交通中断等现象。路基边坡稳定性的问题已对公路运行形成较大的安全隐患。 为消除安全隐患,该局投入资金170余万元,重点对K40+075、K48+665等9处近8000平方米的高危边坡采用对浮石、风化石进行清理或一定程度的削坡后,在坡面挂SNS柔性防护网的措施进行防护治理。工程实施后将进一步确保该路段边坡稳定和行车安全,同时达到与周围环境协调,保持生态环境,美化公路的效果。
  SNS柔性防护网主要用于边坡防护,特点以安全为主,在同行中比较有新意。提起国家今年对边坡防护网实行专项资金sns柔性防护网系统的开放性特点扶持政策时,黄涛表示,国家扶持企业,在增加国人防范意识同时,也为企业进行很多更好的生产打下了很好的基础。

目前边坡防护网产品多种多样,各种被动防护网材质的都有,对于应用在不同场合的边坡防护网采用的材质也种不相同。一般的边坡防护则采用高锌钢丝网,上锌量从80g-200g不等,在高山上用的防护网材质必须能达到常年防腐,既要柔性还要刚性,安平县连璧网业生产的边坡防护网,柔韧防护网独特的勾编工艺,可使网面本身具有很好的柔性,而勾编所用的丝都是高上锌量的钢丝,其特点是坚硬不易被破坏,无论是防腐性能还是柔韧性能在很多防护网产品中都比较突出,如果边坡防护网的钢丝网的质量、上锌量都达不到国家要求,仅仅可供短时间的使用,这样不合理的分配安装会给人们造成巨大的损失,所以提醒广大客户,SNS柔性防护网自身的产品特点及在防护中所起的影响购买防护网一定要购买材质优良的被动防护网。

sns柔性护网系统除对稳定边坡有一定作用外,地下水可以自由排泄,避免了由于地下水压力的升高而引起的边坡失稳问题;同时还能抑制边坡遭受进一步的风化剥蚀,并且对坡面形态特征无特殊要求,不破坏和改变坡面原有地貌形态和植被生长条件,其开放特征给随后或今后有条件并需要时实施人工坡面绿化保留了必要的条件,绿色植物能够在其开放的空间上自由生长,植物根系的固土作用与坡面防护系统结为一体,从而抑制坡面破坏和水土流失,反过来又保护了地貌和坡面植被,SNS柔性防护网的分类及产品特性实现最佳的SNS柔性防护网和环境保护目的。
