| Zusammenfassung: | PURPOSE:To permit large stones to be stored during a great flood by a method in which unit structures formed by combining columns with polygonal frames with steel tubes by couplers are connected to each other and set crossingly in the flow direction. CONSTITUTION:Beams 11 and 12 of steel tubes are polygonally fabricated with couplers 3 and connected with diagonal members 13 to form a frame 2. The couplers 3 are connected with columns 14 to make up a structure with 1 which is in turn connected to several sets of concrete bases or pile bases set at a given interval crossingly to the flow direction on riverbed. The units 1 are further connected with other structure units 1a - 1d through the couplers 3 vertically and/or horizontally to make up a structure 20. |
