发明名称 APPARATUS AND METHOD FOR PROTECTING UNDERGOUND CABLES
摘要 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.
