METHOD FOR CREATING NAVIGABLE HYDRAULIC STRUCTURE, GATE AND DAM FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC E02B5/04 E02C1/00 

FIELD: hydraulic structures.

SUBSTANCE: invention is related to creating navigable hydraulic structures, their operation, to methods for building a gate in order to ensure guaranteed depths of the river for navigation. The method for creating a navigable hydraulic structure includes creating a gate and a dam, according to the invention, the gate is made according to shipbuilding technology, transported using a dock pontoon, installed and fixed in place, a dam is attached to both sides of the gate chamber, which consists of two parts, each of which is made in form of panels made of durable airtight fabric and fixed to the corresponding side wall of the gate at one end, and to the coastal capital structure at the second, while the upper longitudinal edge of the dam is attached to the rope with floats, and the lower longitudinal edge is attached to the rope with anchor weights. The gate contains a gate chamber, a gateway, a bypass system, drive mechanisms, automation and tracking equipment, the walls of the gate chamber are fixed on the frame of the base and fixed with stops in a vertical position, gateway leaves are hinged to the walls, which are fixed in the open position on restricting columns, in the underwater part, compartments with valves and holes for water bypass are installed on the walls, an electric generator is installed, attachment points for the base to the bottom are made on the frame, and attachment points for the panel and cables of the flexible dam are made on the walls of the gate chamber. The gate can be operated automatically. The navigable hydraulic structure contains a lock and a flexible dam, the design of which is given above.

EFFECT: when implementing the proposed method and design of a navigable hydraulic structure, a number of positive effects will be observed: the costs and time for creating a navigable gate-dam complex are sharply reduced; with the end of navigation, the flexible dam is removed or lowered to the bottom, the gateway is opened and fixed until spring, practically the river returns to its natural state; if necessary, the gate, disconnected from the flexible dam and piles supporting it on the bottom, can be moved to another place with the help of a dock pontoon or barge or removed into the backwater and installed only for the duration of navigation; due to the relatively low cost of manufacturing of the gate and the dam according to factory technology, short installation times, there can be many such hydraulic structures, which ensure guaranteed depths on rivers that are considered non-navigable.
