WAVED SHAPE CAISSON FOR BREAKWATER OF HARBOR

摘要

The present invention relates to a caisson used for construction of a breakwater and a harbor. Curved protruding walls (11) and curved recessed walls (12), which have slits (21) formed thereon in multiple layers, are formed on a front surface of the caisson, which is positioned outside the harbor, to form unevenness in a planar shape of Taegeuk, thereby expanding an incidence surface for waves and also preventing a phenomenon that stress is concentrated on a specific part of the structure of the caisson. The protrusions (30) protruding outwardly are formed on portions, to which caisson separation walls are coupled, of front surfaces of the curved protruding walls (11) and the curved recessed walls (12) to reinforce coupled parts of the separation walls (15) and simultaneously induce distribution of wave pressure and introduction of incident waves into the slits (21). An upper end of a compartment (20) formed on a rear wall (14) of the caisson, which is positioned inside the harbor, is formed in a stepwise manner to cancel reflective waves, which have various wavelengths and incident angles and are propagated inside the harbor. According to the present invention, it is possible to obtain an effect of securing durability of the breakwater and the harbor and maintaining a constant temperature of the harbor by improving structural stability and wave canceling performance of the caisson.
