  • RC ROMOVABLE COLLAR
  • the CNC/ILDS sleeves and RC collar can be installed on the cable holding the fence post, which, in turn, stretches rock fall drape net.
  • the drape net, fence post, and cable constitute the rock fall mitigation fence system (RFMFS).
  • a rock fall mitigation fence is frequently used to protect the traveling vehicles against potential hazards of falling rocks.
  • the fence system is composed of the fence cable, fence posts, and rock fall drape net resting on the cable, which, in turn, is stretched and supported on the fence posts and cable anchors.
  • the fence posts are embedded in rock and the cable is connected to the ground anchor embedded in rock.
  • the RFMFS functions as a flexible fence system for retaining falling rocks by dissipating their dynamic energy during the back and forth swing upon rock impact.
  • the mass of falling rocks varies a great deal. It can range from a few hundred pounds to many tons.

  • Figure 2 shows a CNC/ILDS and a RC installed on a cable.
  • the CNC/ILDS sleeve is a cylinder made of an appropriate material (usually steel) and has an appropriate diameter, length, and thickness for embracing a cable or post with a clearance for near frictionless rotation. The thickness and material type should be selected to provide sufficient strength to prevent the puncture by the rolling rocks.
  • the CNC/ILDS Upon contacting any high ⁇ speed rolling rock, the CNC/ILDS rotates nearly frictionless about the cable and, thereby, avoid cable cut.
  • the sleeve and collar can be made of any materials deemed corrosion resistant, and sufficiently strong against the destructive force of rolling stones, wind, vehicular impact, or any other forms of impact force.

  • Figure La illustrates the plan and side views of a CNC/ILDS sleeve. It is a cylindrical tube of any appropriate material made to loosely embrace a cable or a post to allow its near frictionless rotation about the cable or post. This mechanism allows a CNC/ILDS sleeve to deflect a rolling rock upon contact and, thereby, reduce the failure potential of the fence cable.
  • Figure 1.b illustrates the RC collar that can be easily installed and removed from a cable for easy construction and repair. The collar is positioned between two different-size CNC/ILDS sleeves to prevent a smaller sleeve from slipping into a larger one.
  • Figure 2 shows a cable with CNC/ILDS sleeves and a RC collar between two sleeves. INSTALLATION OF CNC/ILDS
  • CNC/ILDS sleeves can be installed along the whole length of the cable and/or the post.
  • the functionality of the CNC/ILDS is explained as follows:
  • a CNC/ILDS can rotate nearly freely around the cable and post that they are protecting.
  • RC collars are installed between two CNC/ILDS sleeves at the lowest pint of the cable, a larger sleeve for protecting the connection just above the ground anchor and the smaller one for protecting the cable right above the cable connection the larger sleeve to prevent the smaller sleeve from slipping into the larger one.
  • the fence system has to be structurally designed. Many instances offence failures showed that the falling rocks severed the cables, and uprooted or severely bent the fence post. The failure of a RFMFS imposes a safety risk of traveling motorists from falling rocks as demonstrated in the recent rock fall event along Interstate Highway 1 70 near Georgetown, Colorado on April 8, 2004.
  • the fence cable needs to be protected from the cut by the large falling rock and the CNC/ILDS sleeve in this invention provides such protection.
  • the RC collar enhances the constructability because it can be easily opened and removed, the large sleeve slips over the small sleeve and cable unbolted to allow sleeve removal and repair.

Abstract

L'invention concerne un manchon CNC/ILDS et un collier amovible (RC) conçus pour fournir un moyen de protection à des piquets et à des câbles de clôtures. Sans une telle protection, une clôture de protection classique contre les éboulements cède fréquemment lors de chocs provenant d'importantes chutes de pierres tombant à une vitesse angulaire élevée et avec un élan considérable comme il est démontré dans plusieurs incidents provoqués par des éboulements. Les manchons CNC/ILDS de l'invention entourent un câble ou un piquet pour défléchir les pierres qui tombent en tournant sur elles-mêmes à une vitesse angulaire élevée et avec des forces d'impact associées élevées, ce qui permet ainsi de protéger le câble ou le piquet en amortissant ou en évitant les chocs provoqués par l'éboulement. Le collier amovible (RC) est utilisé lorsque deux manchons CNC/ILDS de tailles différentes sont utilisés. Ceci permet d'éviter qu'un petit manchon ne se glisse dans un grand manchon, et permet d'assurer la protection pour laquelle le manchon CNC/ILDS est conçu. En outre, le collier (RC) est facile à construire et permet également une maintenance facile du système de clôture d'amortissement d'éboulement. Par conséquent, le manchon CNC/ILDS, ainsi que le collier amovible (RC) entourent des piquets et des câbles de clôture, ce qui constitue un moyen de protection de ces câbles et de ces piquets, et ce qui permet d'améliorer également la sécurité des automobilistes.
