CONSTITUTION: The process of creating a seawater exchange breakwater is composed of: seating an open sea block(10) on a dead stone foundation(2); installing a concrete floor(15) provided with numbers of water passing grooves(14); seating several steps of hollow blocks(20) under the open sea block; filling the inner space with dead stones; seating an upper structure(30) on the top of the dead stone; fixing a cap concrete(40) with arm keys(41,41a) to the top of the upper structure. Consequently, the breakwater consists of a lot of components, therefore transportation and handling become simple and easy.
