Underwater surveys

The purpose of the research refers to the identification of the structure of a ground medium (material) in terms of continuity and homogeneity under concrete slabs of reinforcement structures at the bottom below and above the dam and vertical expansion joints of reinforcement walls of the bank from upper water and the lower dam.

I stage - above-water section

The research covers a medium (place) along vertical concrete expansion joints at walls of the left bank within the section above the level of water surface.

II stage - under-water section

A medium (place) under concrete slabs of reinforcement structures of lower and upper waters

The effective transverse width of beam penetration of is about 1,0 m.

In view of the extensive scale elevation, radar profiles demonstrate a sizeable height difference in the level of slabs in relation to their factual position caused by obstacles resting at the bottom or their corrugation.
