Изобретение относитс к конструкции гравитационных и арочных плотин на основе предварительно изготовленных железобетонных элементов и может быть использовано в гидротехническом строительстве.The invention relates to the construction of gravity and arched dams based on prefabricated reinforced concrete elements and can be used in hydraulic engineering.

Цель изобретени - снижение стоимости строительства и повышение технологичности возведени .The purpose of the invention is to reduce the cost of construction and improve the manufacturability of construction.

На фиг. 1 представлен план выполнени плотины; на фиг. 2 - разрез А-А на фиг. I; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 shows a dam implementation plan; in fig. 2 shows section A-A in FIG. I; in fig. 3 shows a section BB in FIG. one.

Плотина имеет каркас, который образован из предварительно изготовленных плоских железобетонных элементов полной длины 1 и неполной длины 2, которые смонтированы в плане вдоль пр мых, ориентированных в двух взаимоперпендикул рных направлени х (фиг. 1). Таким образом, что противоположные по длине элемента торцы элементов одного направлени , например вдоль плотины, примыкают к серединам элементов другого направлени , идущего поперек плотины. Как видно из фиг. 2, элементы 1 и 2 по русно уложены друг на друга с перев зкой по высоте сооружени и имеют на противоположных торцах выстуПод гидростатической нагрузкой плотина работает как монолитный блок, поскольку вс конструкци св зана воедино каркасом из стеновых панелей 1 и 2, работающим наподобие ферменной конструкции, которой сыпучий материал 6 придает дополнительную жесткость.The dam has a frame that is formed from prefabricated flat reinforced concrete elements of full length 1 and partial length 2, which are mounted in plan along the straight lines, oriented in two mutually perpendicular directions (Fig. 1). Thus, the ends of elements of one direction opposite in length of the element, for example along the dam, are adjacent to the middle of elements of another direction running across the dam. As can be seen from FIG. 2, elements 1 and 2 are stacked on top of each other with intersection along the height of the structure and have a dam at opposite ends of the hydrostatic load; , which bulk material 6 gives additional rigidity.

Вместе с тем, св зи между элементами конструкции достаточно податливы, что устран ет угрозу разрушени сооружени под 10 действием сейсмических нагрузок. Сыпучий материал 6 образует большую часть веса плотины обеспечива ее сцепление с основанием силами трени . Наличие выступов и впадин преп тствует сдвигу верхних русов относительно нижних и возникновению трещин в горизонтальных швах. Этому же преп тствует сыпучий материал.At the same time, the connections between the structural elements are sufficiently flexible, which eliminates the threat of destruction of the structure under seismic loads. Bulk material 6 forms a large part of the weight of the dam ensuring its adhesion to the base by friction forces. The presence of protrusions and depressions prevents the upper Rus from shifting relative to the lower ones and to the occurrence of cracks in the horizontal joints. Bulk material also prevents this.

Under hydrostatic load, the dam operates as a monolithic block, since the entire structure is connected together by a frame of wall panels 1 and 2, working like a truss structure, with which the bulk material 6 imparts additional rigidity.

At the same time, the links between the structural elements are sufficiently flexible, which eliminates the threat of destruction of the structure under seismic loads. Bulk material 6 forms a large part of the weight of the dam ensuring its adhesion to the base by friction forces. The presence of protrusions and depressions prevents the upper Rus from shifting relative to the lower ones and to the occurrence of cracks in the horizontal joints.
