CHEOPS, CONSTRUCTION BY INTERNAL RAMPS ?
The sights of phases of construction by internal ramps below are issued from our thesis and deposit N° 2003050127 on march 2003.

 
Another possibility of implementation of constructions by internal ramps could be considered from my own point of view as the only one possible.
Nothing new, this principle was mentioned in the 16th century by Arab travelers such El Maqrizi and is mentioned for years lien29Langue au chat? on various internet sites.


Once the exact positioning of Cheops for example was done, it is logical to think that in fact the underground parts were initially carried out and we have until our days the remained example at Abou-Rouash.

In addition I explained for the slipping of the blocks which represent such masses, the technical reasons which make very improbable the use of lateral or frontal ramp. (Click here to consult the traditional assumptions).
On the principle assumption shown in what follows, the blocks are hoisted by interior ramps. (Amount and slope will be adjusted to the needs in accordance with the layers level ). They are mechanically contained and their mass still remains components usable for the construction.
In fact, the blocks slipped at the desired level don't require after any more than to be slipped lastly towards the external edge of the pyramid.
This installation is simpler and easier than to raise them successively to the needed level from the base of the pyramid with levers or oscillating machines.

Phases of construction (Click on the arrows to make travel the sights).

Note: These sights are not a technical representation but only one explanatory support on the principle.

The sights of phases of construction by internal ramps below are issued from our thesis and deposit N° 2003050127 on march 2003.

Il is obvious that the number of ramps could be different, and the principal access necessarily did not take seat on the East side. They are not restrictive either in the fact of also having to take into account flows of the human personnel.

Phases 
The traces of these phases remain still apparent on the Cheops'pyramid.
Backfilling of a first layer by sparing an access to the East ramp and towards North in order to allow a maximum backward for the next ramps.
Construction of the successive levels of North towards the South with access by various ramps stabilized by their lateral abutments which can be simple support or enclosed. Their number and slopes are variable according to masses' transit as well as the traffic of the workmen.
Construction of the Queen Chamber's level. As an example this level could have taken seat at an altitude of 40 Cubits and have easily profited a length of ramp of about 120 cubits for the slope (2) and 240 cubits for the slope (3), ie: a coefficient of slope equal to 40/240 which means a slope of about 16%.
If this value proved to require too great efforts for the slip, nothing forbade to multiply the ramps by a realization of these in parallel at successive levels.
(the representation on the sights is not in proportion and it is advisable to remember that for example the width between the pyramid's East wall and the QueenChamber is about 50 meters! A ramp measuring only a few meters of width it was easy of constituting several parallel ramps as well as stages in levels).
In any case, there is storage of the heavy blocks at each level which are corresponding with the followings.
Closing the eastern side with maintenance of an access to the ramps.
Construction of the GreatGallery then of the King Chamber.
Preparation of an important storage areas on the higher level of the king Chamber, area which on this level represents a square of 100 Cubits side, that means approximately 50 meters. I.e. nearly 2.500 square meters of useful storage area which is undervalued in accordance with the surface necessary for the last useful approach ramp for the blocks.
Routing and storage on this level of the heavy elements which are necessary to the completion.
Backfilling and closing of the partially open remained side.
From this moment, only filling components will have to be carried. It is logical to suppose that it was done by internal or external human chain.
To finish construction, the same principle of internal ramps will be used starting from the level of storage of the blocks (11).
Completions by limestone coatings of Toura and decoration.
Note:
This concept of storage (and thus of loads) could possibly constitute a response to the presence of the rooms of discharge located at the top of the King Chamber. (Those can appear as a nonsense or useless because the Queen Chamber which is lower located and undergoes stronger compressions does not have any).
The sequence of construction induces a construction by rises and successive withdrawals from the South towards North, and more precisely starting from South-west. This movement is immediately apparent when the cut of the pyramid is seen.
If unknown hollow volumes exists, they could thus, by disregarding underground level, take place in the Southern or South-western part.
