PROBLEM TO BE SOLVED: To provide a surface contact type reinforcing structure capable of easily carrying out of a reinforcing structure of a footing. SOLUTION: The reinforcing structure is so constituted that sheet piles 1 are provided so as to come into contact with the footing F. A border between the side of the footing F and the sheet pile 1 is reinforced with footing concrete 2. The footing concrete 2 is placed up to the upper surface from the lower surface of the footing F. Since the footing F is not thereby connected with the sheet pile 1, connection work can be eliminated. The footing F is not required for chipping, and any sectional deficit also does not occur. Since the footing F is not rigidly connected to the sheet pile 1, vibration can be slightly made. As a result, in the case a great earthquake occurs, and even if big acceleration amplitude occurs, the occurrence of excessive stress in the lower part of a pier can be prevented. Since the sheet pile is used for a form, the installation or removal of the form are not separately required and, at the same time, a small excavated area remains unchanged.
