The subject underground cable assembly protection system of this invention comprises a plurality of rigid substantially impact-resistant elongate protective channel members. Each of these channel members defines an enclosed compartment for housing the cable assembly. The system of the present invention also includes means for interconnecting adjoining channel members to each other. In this way, the underground cable assembly protection system can be formed. The channel member and/or the interconnecting means can comprise a polymeric material, and more preferably an impact-resistant polymeric material such as high-impact PVC or polyurethane. The channel member and/or the interconnecting means can comprise a substantially U-shaped cross-sectional configuration, more preferably the substantially U-shaped cross-sectional configuration of each the channel member comprises a horizonal base section having a pair of respective ends and a pair side sections attached to the pair of respective ends of the horizonal base section. The adjoining channel members of this invention typically form a joint therebetween and the interconnecting means, which is preferably a lap joint section, that overlaps the joint and in turn the adjoining channel members.
Le système de protection pour ensemble de câbles souterrains de la présente invention est constitué d'une pluralité d'éléments rigides de caniveau protecteur allongé résistant substantiellement aux chocs. Chacun de ces éléments de caniveau définit un compartiment pour loger un ensemble de câbles. Le système de la présente invention comprend aussi un moyen pour assembler les éléments de caniveau adjacents. Ainsi peut se former le système de protection pour ensemble de câbles souterrains. L'élément de caniveau et/ou le moyen d'assemblage peuvent être constitués d'un matériau polymérique et, de préférence, un matériau polymérique résistant aux chocs, tel du PVC ou du polyuréthane à haute résistance aux chocs. L'élément de caniveau et/ou le moyen d'assemblage peuvent être de section substantiellement en U et, de préférence, la section substantiellement en U de chaque élément de caniveau comporte une base ayant une paire d'extrémités respectives et une paire de parois latérales attachées à la paire d'extrémités respectives de la base horizontale. Les éléments de caniveau adjacents de la présente invention forment typiquement un joint entre eux et le moyen d'assemblage, lequel est de préférence un joint à recouvrement, recouvre le joint et chevauche les éléments de caniveau adjacents.
