PURPOSE: A sheet-integrated coupling band for corrugated steel pipes is provided to prevent a water leakage at the joint portions of both ends of corrugated steel pipes. CONSTITUTION: A sheet-integrated coupling band for corrugated steel pipes comprises a watertight sheet(180), a coupling band(140), a coupling member(160), a plurality of through holes(166), and bolts(162). The watertight sheet covers the outer periphery of a corrugated steel pipe(120). The coupling band is formed on an end of the coupling band to cover the outer periphery of the watertight sheet. The through holes are formed in the coupling member. The bolts pass through the through hole and coupled with nuts.
