SU77A1 - Downpipe at the dam - Google Patents

Description

In the drawing, FIG. 1 is a plan of the proposed downpipe; FIG. 2 is a section through it in line ab-b-d in FIG. one; FIG. 3 is a view of this pipe from the side of the pond, and FIG. 4 is a cross-section of the pipe along the line o - w in FIG. one.

The proposed downpipe, made exclusively of iron-concrete, consists of a vertical pipe A, which is laid inside the pond, at dam B, and, decreasing in diameter along a special curve, passes into the horizontal pipe B, located under the dam. Pipe A has two cheeks D on the pond side, forming chamber D which is closed on the pond side with shields d laid in the grooves of the U-shaped iron embedded in concrete with bolts fixed in its thickness, with the heads of the bolts sunk in shields d. Each flap d has two iron brackets for easy lifting out of the water. On top of the shields, a frame with a grid is laid in the same grooves. Chamber D has an outlet hole E. In the upper section of the pipe A, eight I-struts are sealed and protruding 0.6–1.5 meters above the section. Frames with metal grids are laid between these racks. To the top of the scientific research institute there is a cut of pipe A between the uprights I a round iron lattice i is laid to hold large objects that could get into the pipe with large water over the nets. All the splash screens, nets and lattice are adapted in such a way that they are under deputy; Kami and can not be removed by unauthorized persons.

The described downpipe acts as follows: the diameter of tubes A and B must be calculated so that they can pass through the most hollow waters, without allowing the water level above the dam to be exceeded. Based on the foregoing, the height of pipe A is made so that, with a known rise in the water level y, the latter overflows through the upper cut of pipe A and flows into it, and then, through pipe B, leaves the dam. Chamber D with shields E and hole E serves to completely lower the pond and adjust its level.
