PROBLEM TO BE SOLVED: To rehabilitate a water way with a curved section without decreasing workability. SOLUTION: In the rehabilitated water way 1, a plurality of units 60 using a plate member 59 are installed in an existing water way 90. The plate member 59 comprises a short side plate 62, a long side plate 63 and a bottom plate 65, which are arranged in a mutually opposed manner. The space 66, in which two lateral portions on both upper and flow-direction sides are opened, is formed inside the unit 60. The plurality of units 60 are arranged in the existing water way 90 in such a manner that lateral opened portions are connected together in a joined manner and that a curved space 66 is formed so that an upper portion can be opened and so that the side of the short side plate 62 can serve as an inside. Additionally, when the unit 60 is arranged in the existing water way 90, an arrangement operation is performed by using a connected unit member 61 in which the plurality of units 60 are preconnected together.
