Zusammenfassung:	PURPOSE:To form a multi-service culvert which has flexibility to follow with a displacement produced in the multi-service culvert and thereby protects a joint unit from water leakage, and what is more, which can be waterproofed with ease without generating public hazards and enhance construction accuracy as well. CONSTITUTION:A multi-service culvert 1 is constructed on a polyurethane resin layer of floor concrete 2 where a polyurethane concrete coating film 4 is coated at the thickness of about 3mm. A joint area is coating with a polyurethane coating band 4a at the thickness of about 5mm.
