Accropode is a special kind of concrete block that is used to build big things like sea walls to protect the shore against strong waves. The word "accropode" comes from two French words: "accrocher" which means "to hook" and "pode" which means "foot".
The accropode looks like a big foot or a big shoebox with a lot of tiny squares on it. It is shaped like this so that it can fit together with other accropodes like a puzzle piece to create a strong wall.
When builders use accropodes, they start by first building a layer of big rocks to make a base. On top of these rocks, they then stack the accropodes in rows, like a stack of Lego blocks.
To keep the accropodes securely in place, they pour concrete into the spaces in between and around them. This concrete is like a glue that holds everything together.
The accropodes are important because they protect the land from being eroded by the waves. They also create a calm area behind them where boats can dock safely.
So, we can say that the accropode is a special kind of block used to build strong walls to protect the shore, and it looks like a big foot or a big shoebox with a lot of tiny squares on it, and to keep it in place, builders use concrete to glue it together with other accropodes.
