COMPOSITE MOBILE DERIVATIONAL WATER CONDUIT AND METHOD OF ITS CONSTRUCTION Russian patent published in 2017 - IPC E02B9/02 

FIELD: construction.

SUBSTANCE: invention relates to hydrotechnical and hydroelectric construction and can be used for creation of pressure water conduits, derivational, hydroelectric pumped storage, etc. hydroelectric power plants, as well as pump stations. Composite mobile derivational water conduit (CMDWC) includes a water intake of syphon or other type, water-supply sections, a composite water conduit from traditional rigid, as well as soft and flexible composite nanomaterials with shape memory, which include an outer shell, two inner shells with an additional coating from composite nanomaterials, which together are flow-guiding elements, at intersections of landsliding areas, as well as terrains with complex elements of orography: ravines, downwarpings, etc. CMDWC is suspended by cable-stayed systems fixed on supports, and there are devices for damping a hydraulic impact and monitoring technical state of the CMDWC extending in a building of container-type like a small hydro-derivative power plant. CMDWC erection method includes as part of design documentation calculation and development parts, including planning its route, creation of the upper and the lower reservoirs, laying the water conduit itself. Delivery and installation of the water conveying sections are performed directly on the route, where their inner and outer shells are mounted with serial interconnection by means of a flexible link starting from the syphon or another water intake. At hard-to-reach areas of highlands installed are supports and a cable-stayed system, onto which by means of preliminary fixed on the CMDWC shells the water-conveying section is suspended. On underlying sections with high water pressure by means of compensators water conveying sections are connected with the water conduit made of plastic or metal, if necessary, a bandage is installed. Then a building is erected of a container-type small hydro-derivative power plant with a previously installed in it hydroelectric unit, devices for damping the hydraulic impact and monitoring the CMDWC technical state. Further, the diffuser is mounted and conditions are provided for damping the energy in the lower reservoir.

EFFECT: invention increases technically possible hydro-energetic potential of small mountain rivers by using seasonally-active mobile derivational hydroelectric power plants.
