Abstract

Изобретение относитс к области гидросооружений , в частности к технологии возведени мобильных гидрозащитных сооружений в виде подвижных элементов, предназначенных дл регулировани уровн и расхода вод, особенно в период поступ- лени паводковых, тайфунных и вод наводнений Цель изобретени - упрощение конструкции плотины и повышение надежности ее работы при многократном использовании . Плотина выполнена в виде эластичного податливого сооружени , представл ющего собой пространственную камеру , первоначально сложенную в виде ступенчатой пирамиды 1. Концы 3 эластичного материала пирамиды герметизированы с основанием грунта, а полость 6 эластичной пирамиды соединена воздухо- напорной магистралью 4 со средством ресивером и насосами подачи давлени в эту полость. Эластична полость пирамиды 1 защищена разъемным предохранительным кожухом в виде стенок 5, имеющих шарниры у основани грунта. При приближении ситуации наводнени поднимают над уровнем воды эластичную пирамиду, имеющую в верхней части волногаситель и волноломы, работающие по принципу соударени и взаимного гашени набегающей волны 1 з п ф-лы, 5 ил сл сThe invention relates to the field of hydraulic structures, in particular to the technology of construction of mobile hydro-protective structures in the form of moving elements designed to control the level and flow of water, especially during the flood, typhoon and flood waters. The purpose of the invention is to simplify the design of the dam and increase its reliability. with repeated use. The dam is made in the form of an elastic flexible structure, which is a spatial chamber, originally folded as a stepped pyramid 1. The ends 3 of the elastic material of the pyramid are sealed to the base of the soil, and the cavity 6 by the elastic pyramid is connected by means of an air-pressure line 4 to the means of the receiver and pressure feed pumps into this cavity. The elastic cavity of the pyramid 1 is protected by a detachable safety cover in the form of walls 5 having hinges at the bottom of the ground. When a flood situation approaches, the elastic pyramid, having in its upper part a wave suppressor and breakwaters operating on the principle of impact and mutual damping of the incident wave 1 hfl, 5 of the next waves, rises above the water level.

Claims

The claims 15

1. The dam containing the frame in the form of a hollow elastic shell, the cavity of which is connected to the pressure system, and the side walls are fixed with end sections within the base at the bottom of the reservoir. characterized in that, in order to simplify the design of the dam and. to increase the reliability of its operation, with repeated use, it is equipped with an external protective shell with a drive, flexible 5 connections, as well as an additional drive connected with a longitudinal shaft, while the side walls of the inner shell are made in the form of a corrugated pyramid with a base at the bottom of the reservoir, and between 10 walls of the pyramid placed an additional drive with a longitudinal shaft, which is made stepped in plan, formed of rings of various diameters and connected by flexible connections with the protrusions of the corrugations at the locations of the rings of different diameter.

2. The dam according to claim 1, characterized in that it is provided with a hinge for rotating the outer protective shell, mounted on the base at the place of attachment of the end sections of the protective shell to it.
