Description

one

The invention relates to a hydraulic engineering construction, and to, in particular, to structures of high mixed-type dams, built rocky foundations.

The purpose of the invention is to reduce the material capacity of the structure and the cost of building a hydroelectric complex with a near-hydroelectric station.

FIG. 1 shows the station part of a dam with a near dam hydroelectric station, cross section; in fig. 2 is a section A. A. in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - GT in FIG. one.

The dam includes a stop prism 1, made of coarse-grained soil, and concrete buttresses 2 with top 3 and bottom 4 tips located within 22-25 m. The top tips 3 serve as stops for reinforced concrete plates 5 of the screen placed in the slots 6 arranged behind the tips 3. The plates 5 are mated with the base using a tooth 7, under which the cementing curtain 8 is arranged. The seams between the plates 5, as well as between plates 5 and counterforts 2 are equipped with prot

The water intakes 12 are connected to inclined pipelines 16 arranged 25 inside the lower ends of the back connector 2 by means of the upper leg 15, and the pipes 16 are joined to the horizontal section of pressure pipelines 18 by means of the lower leg 17 supplying water to - 30 hydroelectric turbines 13.

Claims (1)

WEIR, including water receivers, a persistent prism from a larger-sized buttresses with stops on the pressure side, screen plates placed between the prism and buttresses of the buttress, and arrays of monolithic stone outline adjacent to buttresses and the screen, characterized in that, in order to reduce the material consumption of the structure and the cost of building a hydroelectric complex with a dam hydroelectric station, pylons are installed above the buttresses in the upper part of the dam, inside which hydroelectric power stations are located, and the gaps between the pylons are closed, olnyh protrusions made to the height of the pylons on their lateral fragile soil, placed inside the surfaces.
