The construction of the Pyramids
For a long time archaeologists and historians have had a debate on
how the pyramids were built, each one of them has a theory of his own and
tries to prevail on the others, making us lose very useful and important
knowledge. Here are some theories.
Ramps for the construction:
One of the main problems that the pyramid builders had to solve was to
lift the heavy stone blocks up to the necessary height. The method used
by the ancient Egyptians was to use ramps and inclined planes of raw
bricks and crushed stone along which the blocks were dragged, after they
were put on the transport sleds
As the pyramid grew in height, the length of the
ramp and the width of its base were increased to keep a constant pending
(about 10%) and to avoid that the ramps should collapse.
Probably there were many ramps that went up the
pyramid on different sides. There are many theories about the
arrangement of the ramps necessary for the construction. If we start
from the idea that first a pyramid in steps was built inside the pyramid,
probably the ramps were connected from a level to the other instead of
leaning at a right angle to the wall of the pyramid.
Other ways of lifting
The sizes of the ramps and the quantity of the material necessary to
build them have stimulated the research to solve the problem of lifting
the construction blocks. The one proposed by L.Croo, uses the principle
of the “shaduf”, actually the Egyptians used it to lift water. Some
types of oscillating elevators, wood mechanisms similar to cradles, are
known, some have thought they were used to lift a stone block, that once
loaded was lifted, sticking some wedges in the curved part to make it
A mistake, even small, in the slope angles of the facades of the
pyramids would have caused a big mistake at the peak corners.
The principles of the construction of the pyramids are known, but the
exact procedures and the techniques used are still unknown.
Some measures show an accurate use of
height of the Pyramid of
perimeter of the base
The mathematical knowledges of the Egyptians were
enough to get a result similar with the calculation.
