The Great Wall of China though appearing a single, continuous stretch is actually a series of walls built over hundreds of years starting from second century BC. But the most of it that remains today was built during the Ming Dynasty between 1368 to 1644.
Over the years the wall has been damaged because of various factors, but mostly for natural causes. Now the Chinese government has woken up to the seriousness of the condition.
Chinese authorities have deployed drones to check the damage that is around 30% presently, reported National Geographic. The sections that are out of bounds for people and the dangerous paths are the most vulnerable according to the Chinese authorities, reports Washington Post.
The drones are helping authorities to map and measure the damaged sections of the walls and give precise data relating to those damagesWith the help of data thus collected by the drones, workers have found it easy to build supportive structures to reinforce the vulnerable parts of structures. Intel’s Falcon 8+ drones which are being used are equipped with the technology to create three dimensional HD images of the Great Wall.Once the weak portions sare identified and their exact conditions are assessed, restoration works start. Donkeys are deployed to haul up the building materials and masons bolster or construct portions to make them strong again
