Изобретение относитс к защитшым покрыти м откосов гидросооружений и может быть использовано на каналах и водоемах, где наблюдаетс выход грунтовых вод на поверхность и резкие копёба-. ни уровней в оды.The invention relates to protective coverings of hydraulic structures and can be used on canals and reservoirs, where groundwater reaches the surface and sharp debris is observed. No levels in odes.

Известно защитное покрытие, включающее клапаны из эластичной пленки, перекрьгоающие расположенные в отверсти х бетонной плиты пористые вставки l.A protective coating is known, which includes valves made of an elastic film, interposing porous inserts located in the openings of the concrete slab l.

Однако такое устройство применимо лишь цп воцопоапорных сооружений осушительно-увлажнигельных систем при небольшом расходе фильтрационного потока . Кроме этого, при низких горизонтах воды в канале данное устройство становитс водопроницаемым,However, such a device is applicable only to the central control unit of the supporting structures of the drainage-wetting systems with a small flow of filtration flow. In addition, at low water levels in the canal, this device becomes permeable to water.

Наиболее близким к изобретению вл етс защитное покрытие откосов гидросооружений , выполненное из полотнищ эластичного материала, расположенных на откосе и в транше х вдоль oiicoca, причем на участках полотнищ, примы-Closest to the invention is a protective covering of the slopes of hydraulic structures, made of panels of elastic material located on the slope and in trenches along the oiicoca, and in sections of panels,

Это за ди1вое покрытие не обладает достаточной надежностыо, так как оно не обеспечивает водонепроницаемости, при превьшении уровн в водоеме над уровнем грунтовых вод;This coating does not have sufficient reliability, since it does not provide water resistance, if the level in the reservoir is above ground water level;

Claims

The protective coating is made of panels 1 pz of waterproof elastic material located in a trash x 2 and provided with waterproof screens 3, Section 4 of the cloth adjacent to the upper wall of the trench 5 has openings 6. In the trench x 5 there are elastic containers 7, outer walls 8 which are made with holes 9. The portions of the panels located in the trenches serve as anchoring elements. For free penetration of groundwater to the holes 6 under the panels 1, a drainage layer 10 is laid. The protective coating works as follows. The ground waters, when pinned out to the surface of the slope, meet on their way the cloth 1 and the draining layer 1 Due to the small resistances and under the force of gravity, they flow down o-bit to the perforated section 4. Here a part of the stream passes through from b and the other penetrates to the waterproof screen 3, is held and assembled by it, creating a pressure regime of groundwater. The output through the holes Q, the filtration flow acts on the elastic tank 7, in which the pressure P is equal to the hydrostatic pressure of water in the channel or reservoir P and, than the hydrodynamic pressure of groundwater (R) Elastic capacity 7 is pressed and provides free flow of ground water into the channel or reservoir . After the release of groundwater under the action of the elasticity of the material elastic capacity takes its original position. When raising the water level in the canal or reservoir above the level. ground water water through the openings 9 of the elastic tank 7 penetrates into its cavity and fills it, the pressure in it becomes greater than the pressure of the ground water (P P Pg Pj-g resulting in the capacity of 7 tightly pressed against the openings 6. In this case, the protective the coating becomes waterproof 814. With a slight difference in the level of surface and groundwater, the coating works depending on the pressure generated by one or another water. The proposed anti-flap coating in the event of groundwater escaping from the channel slope or in the slope of the reservoir provides their free access to the day surface, thereby preventing suffusion, soil bulging, slope creep, lifting and disrupting the integrity of polymeric panels. In addition, when the level of WATER in the canal or reservoir is raised, it ensures the watertightness of the protective coating. the effectiveness of use in the national economy of this invention is approximately 20-25 p. 100 m by increasing the service life of the coating, which can roughly be taken 3-4 times longer. Formula of the Invention The protective covering of the slopes of hydraulic structures made of panels of elastic material located on the slope and in the trenches along the slope, moreover, in the areas of panels adjacent to the upper wall of the trenches, holes are formed, in order to increase its hope it is provided with elastic containers placed in trenches and attached to the sheets, the outer wall of each of which is made from the side of the slope with holes.
