This is about the formwork for manufacturing sofa blocks.

In general, wave dissipating blocks are concrete blocks that are installed in port structures such as breakwaters and revetments to reduce the force of waves by breaking them when large waves invade at sea, and also to dissipate waves through the gaps between installed wave blocks. It is one of the structures used to build a breakwater that acts to attenuate waves that pass through and reflect off the structure, preventing damage to port structures such as breakwaters and revetments, and protecting the coast by preventing waves from overtopping the inland sea.

Sofa blocks are stacked statically or randomly around the breakwater, and it is very advantageous to attenuate a large amount of waves at once when a lot of air space is secured between the sofa blocks. Therefore, it is easy to install and most pillars are used to create a lot of air gaps. Alternatively, it is manufactured in various shapes with support feet in multiple directions.

By breaking waves through multiple pillars or support feet, they are weakened so that they do not radiate again in the gap with other sofa blocks.

Therefore, as much as possible, the surface of the sofa block must have as many contact surfaces as the wave, so that the area touched by the wave increases, causing it to be broken into small pieces by receiving resistance, and the wave effect is drastically weakened to prevent reflected waves and waves from rising and overcoming the upper side of the breakwater. becomes bigger.

Most of these sofa blocks began to be used as covering materials on inclined breakwaters, and countless sofa blocks have been developed in various ways. In general, T.T.P (Tetrapod), which consists of four conical pillars, is widely used.
