A good place to start is Christopher Duffy's study of the Russian Army from 1700-1800:

The older Russian artillery system is covered along with sometechnical drawings, but the newer 1805 artillery system developed and fielded by Arakcheev is not covered.
The new artillery system resembles the older Austrian Liechtensstein System including the adoption of the screw quoin which was not as efficient as the more modern elevating screw.
The licorne (unicorn), the Russian gun-howitzer hybrid, is covered however.
Interestingly, a model of a Russian field piece and limber given to the French and is now in the Musee de l'Armee ca 1850 still shows the screw quoin being used.
The book The Russian Army 1812-1814 shows a Russian field piece, sidearms, limber and other drawings that might be helpful. They are not technical drawings but an artist's rendition, but it can also be a starting place even though it is not a scholarly publication. It is also in Russian.
The illustrations in the link provided by Prince of Essling are from this publication.
Their is also an interesting Russian publication, Arakcheev's Artillery: The Russian Artillery System of 1805 by Alexander Smirnoff which is useful.
Lastly, the two-Volume study on Russian tactics, including artillery, Tactics of the Russian Army in the Napoleonic Wars by Alexander Zhmodikov and Yurii Zhmodikov is excellent and is necessary to understand the problems the Russians had with artillery employment and how they attempted to reform it.
