PROBLEM TO BE SOLVED: To provide an economical slope reinforcing structure which can also be applied to an already-completed banking slope, and can minimize the amount of settlement of a levee crown section of a banking structure in disaster. SOLUTION: A plurality of horizontal drainage piles 21<SB>1</SB>-21<SB>n</SB>and a plurality of oblique reinforcing piles 22<SB>1</SB>-22<SB>n</SB>are each alternately driven into the banking slope; and after they are driven, grouting is applied to leading ends of the reinforcing piles by the injection of a grout material. This banking reinforcing structure restrains the clod between the drainage pile and the reinforcing one, suppresses positive dilatancy on the periphery of the pile during earthquakes, and employs the cantilever beam-type drainage pile, so as to bring about the effect of supporting the levee crown section of the banking.
