METHOD TO CONSTRUCT FLOAT HYDRAULIC POWER PLANT COMBINED WITH LOCK CHAMBER Russian patent published in 2013 - IPC E02B9/00 E04H5/02 

FIELD: power engineering.

SUBSTANCE: foundation under a common structure is assembled from steel or reinforced concrete blocks having sufficient buoyancy reserve, which are towed to the place of riverbed closure, where concrete stops are previously installed to ensure stop of the foundation at the specified point. One of the stops is connected with a coupling dam, under which sag pipes are laid for their connection with water conduits of float power units. Work is completed on build-up of walls on the foundation, using finished standard reinforced concrete boards, inserting them into reinforced concrete stands, and simultaneously the built-up walls at the side of the air lock outside is strengthened by inwash soil. Then both pairs of two-fold gates are installed, leaving them open before the sag pipes are laid, and a passage is closed, which is arranged between the wall of the lock chamber and the coupling dam of the opposite shore of the river. After float power units have been installed and connected to water conduits and power grid, and the site is closed by gates, the float hydraulic power plant with the matched lock chamber is commissioned.

EFFECT: possibility to simplify construction of a float hydraulic power plant combined with a lock chamber.
