How the Great Pyramid was built?
After much research engineering theory was put forward that the Great Pyramid of Giza was built without the use of a giant stingray, as previously thought.
Instead of a giant ramp, pyramid builders used water locks on the Nile to lift blocks of stone by barge to the construction site. This system is simple, but very complex. The Great Pyramid was built level by level, and it happened so. First they were stacked and fastened together stones primary insulating layer. This created the boundary wall of the insulating stones. Then the area was filled with water and isolating stones created an artificial pond.
In the insulating wall of the water gateway that allows roughly shaped inner stones using barges to move into the pond was built. Then the stones were transferred from the barge to the bottom of the pond. When the entire pond filled inner stones, another layer of the Great Pyramid proved to complete. The next step was the addition of water in the pond to fill the area bounded by the second layer of insulating stones. The rise of water in the pond can deliver blocks have the second level of the pyramid.
The above figure shows that the "building" the pond is never too deep. These workers are in the pond, but there are rocks on the treated prior pyramid. The reason that water does not leak out between the treated stones is that the insulating wall is watertight up to the base of the pyramid. In other words, the water fills the gaps between the stones of the inner layer treated on their all the way to the ground and fills the pond at the top.
