PROBLEM TO BE SOLVED: To provide a steel shell support member for a hybrid caisson that may be installed readily and uses a low-priced rubber mat satisfying a necessary friction increasing function.SOLUTION: A steel shell supporting member 10 is a steel shell supporting member for a hybrid caisson made by covering a steel shell 2 with reinforced concrete, the steel shell supporting member supporting a bottom surface support part 2a of the steel shell 2 of the hybrid caisson 1 and securing a cover concrete thickness 4 of bottom plate reinforced concrete. The steel shell supporting member includes a rubber mat 20 laid in correspondence with a location of the bottom surface support part 2a on a rubble mound 7 for increasing friction between the steel shell support part and the hybrid caisson 1, a lower plate material 30 connected on a top surface of the rubber mat 20, and a connection member 40 for connecting and integrating the lower plate material 30 with the steel shell 2, while securing the cover concrete thickness 4. An amount of subsidence of the rubber mat 20 due to a steel shell load is to be within an allowable range.SELECTED DRAWING: Figure 3 |
