The conjugation with the aqueduct is made above the springboard of the service surface spillway. The aqueduct, from conjunction with the tray of the service surface spillway before reaching the horizontal position of the aqueduct, has smooth curvature, allowing the watercourse to undergo without spray, i.e. smooth flow to the outlet, which is made at a considerable distance from the dam base. The aqueduct is throughout rigidly fixed to the bearing supports. The aqueducts themselves are made of stainless steel, or of any known non-corrosive metal, or metal with corrosion-resistant coating and/or concrete and/or reinforced concrete and are solid or modular or precast solid.

The branch pipes are installed in such a way that the water jets emanating from neighbouring aqueducts collide with each other, and the water energy is quenched and its speed slows down. The speed of the water flow of the falling water and the water flowing through the aqueduct is 30-50 m/sec. If this stream is not retarded to the river current (2-3 m/s), then this stream will bring considerable destruction on the shoreline of the river, and also threaten the vessels in the riverbed.EFFECT: rational distribution of water resources and prevention of floods, lowering the level of reservoirs and protecting the dam base from destruction.7 cl, 2 dwg

The receiving section being the screw drum of a conical shape is made of least three strips of trapezoid shape with different dimensions as to width, with their increase as to length of the receiving part, which are twisted in vertical plane in longitudinal direction relative to the proper symmetry axis of the strip and bent along the screw line in transverse direction on a conical mandrel. Two hollow straight-line sections are made in the form of a multiturn screw drum from at least one strip bent along straight lines arranged at an angle to the strip edges, with formation of similar parallelograms located alternately on the strip to the opposite sides; with that, the strip is rolled into cylindrical coils connected to each other along longitudinal edges, with formation on the inner surface of one-directional screw lines and screw pockets of a polygonal shape. Distance between straight bend lines is equal to length of each element of the polygon. Shape and dimensions of the pockets can be different both as to shape and dimensions and as per perimeter of straight-line sections. A hollow sector is made in the form of a multiturn screw drum provided with helical grooves inside at an angle to its axis, in the form of pockets of a polygonal shape in the form of different geometrical figures with four and more lateral sides; with that, distance between straight bend lines is equal to length of each element of the polygon and assembled of sections made from a strip rolled into a ring, a polyhedral surface and formation of squares that are different as to dimensions and have two parallel sides located parallel to each other. Sections are connected to each other with free sides of the above squares in the form of a hollow sector.EFFECT: providing cleaning of stagnant and polluted waters of bays and gulfs by creation inside them of constant circulation of clean water due to turning and direction of coastal currents deep into their water area, increase of speed of artificially created currents with further output to an open sea with these currents of pollutions of bays and gulfs.23 dwg

ethod of washing storage pond of livestock wastes (versions) // 2552358
FIELD: agriculture.SUBSTANCE: method consists in creating a closed water area in the form of a storage pond 8 with the area of accumulation of sludge from liquid flows. The storage pond 8 is a water area with a levee 12, in which body the inlet water intake hole is made, and the opposite - a water receiver 9 of the water intake pipeline 22. According to the first embodiment of the method, at the bottom of the storage pond 8 the closed air-injecting devices 14, 15 are mounted to form a number of beams diverging from the device as horizontal perforated pipelines 16 in the direction of the base of the upper slope of the dam 12. The perforated pipelines 16 end with a dead end. The air-injecting devices 14, 15 are connected to the central supply pipeline 17, 18 connected to a source of compressed air. With the increase in the accumulation of sediment in the form of sludge in the zones of the storage pond 8 the air supply in portions into the air-injecting devices 14, 15 is resumed with brief connection of the compressor 19 on the command of the time relay 20 on the air duct in the intake pipeline of the closed air-injecting device. Breaking through the holes of the perforated pipeline 16, the compressed air loosens and roils the sludge, with simultaneous saturation of manure flow with it, and transports it to the discharge water intake pipeline 22. As the reduction in the sludge layer in the storage pond 8 the air supply into the air-injecting devices 14, 15 is stopped. According to the second embodiment of the method, in the storage pond a floating platform is placed, on which a compressor is located, connected to the pressure hose air duct. The nozzle of the pressure hose air duct is made in the form of a metal trunk with a perforation in its end part, attached to the rod with graduations in height and in the section of sludge residual accumulation, the end of which is inserted into the precipitate formation. The floating platform is attached on both sides of the dam using a rope and block system in the areas of erosion of the sediment of sludge precipitation.EFFECT: increased efficiency of transport capacity of roiled manure flow coming from the livestock complex, and increased in functional capabilities of the storage pond with possible disposal of flows on irrigated fields of reclamation.2 cl, 6 dwg
Energy dissipator for open canals // 2551992
FIELD: construction.SUBSTANCE: vertical longitudinal flow directing element 4 in the form of supporting pier with radome 7 in the lower part is installed in steep canal 1 with the revetment walls and bottom between the longitudinal walls 5 and 6. The length of the flow directing element 4 is larger than the length of vertical walls 5 and 6. The radome 7 is oriented along the axis of transit canal and divides it into two canals with equal input cross-sections. The end portion of the radome has convex shape.

Water outlet from channel with steep slope // 2550421
FIELD: construction.SUBSTANCE: water outlet comprises the inlet 1 and transit 2 channels, associated with water intake gallery, having the water inlet opening in the upper part, covered with grid 11. Grid 11 also covers the V-shaped threshold 10, which separates the sediments before the bottom slot of gallery into coarse fractions. The side walls of the supply channel 1 are provided with guide elements with possibility of their displacement towards the threshold. Guide elements are designed with L-shaped vertical walls 13 with shelves 14, placed above the bottom of the supply channel 1. The lower edges of vertical walls are installed relative to the bottom of the inlet channel 1 with gap. Gallery is made with intake portal in the form of tube, the upper part of the case of which with oblique cut 6 is located above the slotted hole of the gallery. Due to the fact that the cross-section portal of tube with the inlet portion 5 is located slightly above the bottom of the chamber, the water flow to the discharge pipeline is increased, and flow regime through the portal into the transit channel 2 occurs without splashing and all sediments go down. In the presence of bending, the flow speed profile is more uniform in the pipeline, which reduces the tendency of flow separation from the inner curved wall and reduces the energy losses along the length of the pipeline, caused by the vortex turbulence. Pressure losses in the inlet portion at the presence of tubular portion, curved in three dimensions, as in the outlet portion of the pipeline, are reduced.EFFECT: construction of water outlet as a whole provides its protection against the sediments, as well as in case of the absence of water inlet and simplification of the design at the increased discharge capacity, besides the length of the discharge pipeline is reduced respectively.2 cl, 5 dwg
