Caisson using waste tire

PURPOSE: A caisson using waste tires is provided to obtain excellent wave breaking and wave force reduction effects and prevent the damage of a running water chamber by rotating waste tires and dissipating wave energy. CONSTITUTION: A caisson (100) using waste tires comprises a plurality of compartments (110) and a slip part (120). A compartment is partitioned by a partition. A seawater inflow surface is formed in the front surface of the compartment. The slit part comprises first and second pillars installed inside the compartment and a waste tire (10) rotatably inserted into the silt part using the pillars. The waste tire is fitted to a waste tire holding part. The waste tire rotates by seawater which flows in the slit.
