Description

Известные конструкции арочных плотин требуют п.ри нроизводстке работ по их возведению предварительной пробивки строительного тоннел  дл  отвода воды и устройства перемычек, что удорожает стоимость и удлин ет сроки строительства.Known designs of arched dams require the manufacturing of works for their erection of preliminary punching of a construction tunnel for draining water and making jumpers, which increases the cost and lengthens construction time.

В предлагаемой арочной плотине этот недостаток устран етс  тем, что основанием плотины служит подплотинна  арка, включаема  в тело плотины. Отверстие арки используетс  в гУериод строительства длл пропуска воды.In the proposed arched dam, this disadvantage is eliminated by the fact that the base of the dam is a sub-arch, which is incorporated into the body of the dam. The arch hole is used in the construction of the water passage dll.

На фиг. 1 изображена арочна  плотина, вид с нижнего бьефа; на фиг- 2 - то же, в плане; на фиг. 3 - плотина в поперечном разрезе после заделки подплотинного отверсти .FIG. 1 shows an arched dam, view from the downstream; in FIG. 2 - the same in terms of; in fig. 3 - dam in cross section after the seal of the sublap hole.

Арочна  плотина 1 возводитс  на специально устраиваемом основании в виде горизонтальной арки 2, перекрывающей пусло реки. Отверстие 3 арки используетс  дл  пропуска воды в период строительства.The arch dam 1 is erected on a specially arranged base in the form of a horizontal arch 2 spanning the river bed. Hole 3 is used for the passage of water during construction.

Отметка п т подплотинной арки и ее стрела выбираютс  таким образом , чтобы пропуск воды в период строительства проходил под плотиной . Сама арочна  плотина возводитс  насухо на бетонной постели 4, выравнивающей верх подплотинной арки 2 и берегов. Во избежание передачи недопустимых больших горизонтальных нагрузок арочной плотины иа подплотипную арку верхн   плоскость 5 покрываетс  изол ционным слоем, обеспечивающим низкий коэффициент трени  (асфальтобитумные покрыти , графитова  смазка и т. п.).Mark p m of the dam arch and its arrow are chosen so that the passage of water during the construction period takes place under the dam. The arched dam itself is erected dry on a concrete bed 4, leveling the top of the dam arch 2 and the banks. In order to avoid the transfer of unacceptable large horizontal loads of the arch dam and the subplotty arch, the upper plane 5 is covered with an insulating layer providing a low coefficient of friction (asphalt-bitumen coatings, graphite grease, etc.).

По заверщению строительства плотины и дерривации, а также при необходимости водосбросных устройств производитс  перекрытие русла реки иод подплотинной аркой. .В зависимости от характера каньона и пропуска воды осуществление перекрыти  русла может быть различным: с вспомогательными кессонами, сва ми, металлическими затворами и т. д.Upon completion of the dam construction and construction, as well as the need for spillway devices, the iodine arch is blocked. . Depending on the nature of the canyon and the passage of water, the implementation of blocking of the channel may be different: with auxiliary caissons, its own, metal gates, etc.
