Great Wall of China ends in the sea (video)
The Great Wall of China ends inside the sea. How was it built?
Summary: To prevent enemy cavalry from circling the wall through the ice the soldiers cut through the ice, but the sea froze with it and failed to achieve the desired effect. The, later, the construction personnel specialized in field exploration and research. An unprecedented marine construction scheme was established under the conditions of the time and creatively built a high wall in the sea. That's how they did it. It has improved the weak links in the coastal area of the Great Wall after over 10 years of preparation.
In 1579, the construction of the Great Wall into the sea began. The Great Wall is made up of huge blocks of granite. These granites come in two main sizes. One is a strip 1 meter long, 0.4 m wide, and 0.3 m high and another kind of similar square shape, 1 meter long, 0.7 meters wide, 0.6 meters high. Besides, ancient people also built an innovative wall cofferdam. Irregular stones surrounded the wall deep in the sea. Similar to the current Hong Kong-Zhuhai-Macao bridge artificial island construction. The stones weigh 2-3 tons and prevent the water from moving. The transportation of stones in the early stage alone cost a lot of manpower and material resources. But throwing rocks into the sea won’t protect the walls.
