SHEET FOR INDICATING UNDERGROUND BURIED MATERIAL CONTAINING LOCATOR FUNCTION

摘要

PURPOSE: A sheet for indicating a underground buried material is provided to prevent a disconnection by enriching a flexibility for increasing a reliability. CONSTITUTION: A sheet for indicating a underground buried material containing a locator function comprises:a underground buried material indicating sheet(2) overlapped after folded toward a longitudinal direction; and a conductive fiber(3) for a locator installed on the surface of the underground buried material indicating sheet. The underground buried material indicating sheet is formed by:weaving a thin synthetic resin tape(4) for forming a filament cross(5); heat-pressing a transparent protecting sheet of a colored polyethylene on the both surfaces of the filament cross for laminate-treating and shaping into a tape.
