. Изобретение относитс к гидротехническим подпорным сооружени м, преимущественно плотинам из гибких эластичных материалов и предназначено дл использ|рвани в качестве водосливной регулируемой плотины на водртоках с неравномерным стоком в . руслах пр моугольного и трапецеидального поперечных сечений.. The invention relates to hydraulic support structures, mainly dams of flexible elastic materials, and is intended to be used as an overflow adjustable dam on water with uneven drainage. channel of rectangular and trapezoidal cross sections.

Известно устройство дл регулировани расхода воды, включающее емкос;ти из эластичного материала, установленные между имеющими несовмещенные .от версти оболочками и сообщаю- . щиес с источником рабочей среды, причем внутрь емкостей введены перф9Рированные трубы, а на верхней и нижней кромках оболочек укреплены жесткие элементы р.A device for controlling the flow of water is known, including containers of elastic material, installed between shells that are not aligned from versts and communicating. A source of working medium, with perforated pipes inserted inside the tanks, and rigid elements p. are fastened on the upper and lower edges of the shells.

Недостатком этого устройства вл етс громоздкость конструкции, больша материалоемкость и энергоемкость.The disadvantage of this device is the cumbersome design, greater consumption of materials and energy consumption.

Наиболее близким техническим решением к предлагаемой вл етс плотина, включающа гибкую оболочку, выполненную по ширине русла из отдельных четных и нечетных вертикальных полотнищ, имеющих возможность , смещени одних относительно других 2}.The closest technical solution to the proposed one is a dam, including a flexible shell made across the width of the channel from separate even and odd vertical panels, having the possibility of displacing one relative to the other 2}.

Однако у этой плотины малое увеличение пропускной способности сооружени , недостаточное гашение энергии However, this dam has a small increase in the capacity of the structure, insufficient energy dissipation

10 потока, необходимость подъемного оборудовани , что в целом снижает надежность ее работы.10 flow, the need for lifting equipment, which generally reduces the reliability of its work.

Цель изобретени - повышение надежности плотины в работе.The purpose of the invention is to increase the reliability of the dam in operation.

Claims

The goal is achieved by the fact that vertical panels are interconnected in the middle part, as well as cable-stayed connections attached 20 to their upper edges, and provided with an elastic filled balloon replaced between the upper sections of even and odd vertical panels, and the lower edges of the latter fixed still. FIG. 1 shows a dam in a working position, a perspective view; FIG. 2 - the same cross section; in fig. 3 - dam with aligned panels, transverse section. The dam includes a flexible shell of even 1 and odd 2 panels, between the upper parts of which there is an elastic filling cylinder 3. Cloths 1 and 2 along the upper edges are connected by cable ties k and in addition they are connected in the middle part by a common attachment unit 5. The lower forming even-numbered panels are movable and have rigid elements 6, to which flexible connections 7 are attached, connecting them with the crest of the dam. The rigid elements are connected by connections 8 to the bottom of the conduit. The lower forming odd panels are fixedly attached by a fixing unit 9 to the bottom of the watercourse. The dam works as follows. 8 the closed position of the cylinder 3 is emptied, even and odd plates 1 and 2 are tightly attached to each other and the dam works with overflow through the ridge. When passing through the flood discharge, the cylinder 3 is forcibly filled, which expands the even and odd sheets. Between them there are gaps into which, along with an iridescent flow, the flow is discharged. There is a collision of streams on the spillway and, consequently, their best damping. At the same time, the height throughout the dam increases and the movable panels are raised by means of flexible links 7, forming bottom and side openings. When this occurs, the collision of the bottom flow with side. In the future, the total bottom flow is impacted with the total surface flow and their mutual damping occurs. After passing through the flood, the bottom openings are first closed, and then the cylinder 3 is emptied and the dam returns to its original position. Claims of the invention: A dam comprising a flexible shell made across a channel width of separate even and odd vertical panels having the possibility of displacing one relative to another, which in order to increase reliability in operation, the vertical panels are interconnected in the middle part, and also cable-stayed connections along their upper edges and provided with an elastic filling balloon placed between the upper sections of even and odd vertical along the bottom, with the lower edges of the latter not fixed odvizhno.
