Patent Invention 001 is a breakwater construction method using Taegeuk concave-convex caisson, and Patent Invention 002 is a multi-half wave type for harbor and breakwater caisson. The patent invention 003 is a slit caisson with a built-in sponge structure, a breakwater and a quay using the same, and the patent invention 004 is a caisson with a perforated plate formed at the bottom of the inside of the caisson.

The present invention and patent inventions 001 to 004 are common in that they are caissons that attenuate wave energy by allowing waves of waves to flow into the inside of the caisson through slits formed in the caisson.

However, in Patent Inventions 001 to 004, which are prior inventions, the strength of the caisson is inevitably lowered due to the slit formed in the caisson, and the caisson formed with the slit is fatigued due to countless repeated impacts by wave energy on the caisson wall where the slit is formed. It has a lot of problems with being destroyed.

In addition, Patent Inventions 001 to 004, which are prior inventions, do not describe or inherent means for the inclined sofa board and horizontal sofa board, which are means for increasing the durability of the caisson, like the present invention.

Couch in the above term means minimizing or eliminating the wave height (wave height of the wave). That is, wave height means that wave height is minimized as waves of waves are dissipated while passing through the slit.

In addition, Patent Inventions 001 to 004 of the prior invention describe or inherent means for inclined sofa plates and horizontal sofa plates with slits, which are means for further reducing the wave energy of waves that repeatedly apply impact force to the caisson. not.
