The film shows the construction of the most difficult parts of “The Great Wall of Japan” (GWJ), these fragments are 22 m high breakwaters protecting the ports placed on prefabricated reinforced concrete boxes with a height of 14.5 m. These crates are made in dry docks and towed and submerged at the installation site two types of gates closing the water basins were shown in the event of a tsunami alarm.
The first one is a 36.5m high sliding gate and the second one is a sliding and lifting gate. The lifted part of this gate is 15m high and lifted the film also shows the simulation of a wall hit by a ship drifting with a tsunami. It strikes external staircases made of steel that crush the floor but they absorb the impact energy so that the basic reinforced concrete structure of the wall remains.
The cages can be easily rebuilt and allow the use of the beach without the need to pierce the wall (communication takes place over the wall).
The final scene of the film shows the costs of building the wall. Isn’t this interesting?
