CONSTRUCTION METHOD OF TRENCH TYPE CABLE TROUGH

摘要

PURPOSE: A method for installing a trench type cable trough is provided to prevent a cable from being damaged by rounding the edge of concrete. CONSTITUTION: A trench mold(100) is successively combined in a longitudinal direction. A combination wing is buried in concrete on the outer side of the trench mold. A groove is punched to partially bury the bottom of the trench mold in the concrete. An extension unit(141) forms a barrier.
