Gulufin corrugated, wanda aka sani da corrugated duct ko protective conduit, shi ne na'urar polymeric sleeve mai mahimmanci wacce aka tsara don kare kayan prestressing cables da rods a cikin ground anchor da tieback installations. Wanda aka yi shi daga high-density polyethylene (HDPE) ko polypropylene (PP), kayan ya na helically corrugated outer surface wanda yake bayar da structural rigidity yayin da yake riwa flexibility don installation ta hanyar irregular borehole conditions. Inner surface ya na smooth don hana abrasion na tendons a lokacin insertion da tensioning, yayin da corrugated profile ya na karuwa moment of inertia, wanda yake ba da damar sheath don kare lateral loads da bending stresses da ake samu a cikin deep foundation applications. Wannan dual-functionality design ya na cin zarafin corrugated sheath a matsayin na'urar muhimmi a cikin modern tieback da ground anchor systems, musamman inda aka na da bukatar structural stability da corrosion protection na tsawon lokaci.
