BOTTOM SLAB PART STRUCTURE OF HYBRID CAISSON

摘要

PROBLEM TO BE SOLVED: To provide a bottom slab part structure of a hybrid caisson using a rubber mat capable of fulfilling a required friction increasing function and securing a covering thickness of concrete.;SOLUTION: A bottom slab part structure 10 of a hybrid caisson that is installed on a rubble mound is composed of a steel shell 2 and reinforced concrete 3 covering the steel shell 2. The bottom slab part structure 10 comprises a bottom part plate member 30 that supports a load of the steel shell 2 via a plurality of supporting members 40 that support a bottom surface of the steel shell 2, and a rubber mat 20 that is installed on a lower surface of the bottom part plate member 30 so as to increase friction with the rubble mound, lower an amount of settlement due to a load of the steel shell 2, and secure covering (a covering thickness) of the reinforcement concrete 3 in a space under the bottom surface of the steel shell 2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
