Description
Изобретение относится к области гидротехники, в частности к способам сохранения монолитности и плотности ядра (экрана) плотины из глинистого грунта при его деформациях.The invention relates to the field of hydraulic engineering, in particular to methods for maintaining the solidity and density of the core (screen) of a dam from clay soil during its deformations.
Известен способ сохранения монолитности и плотности ядра (экрана) плотины из глинистого грунта при его деформациях путем увлажнения кольматирующего материала [1].There is a method of maintaining the solidity and density of the core (screen) of the dam from clay soil during its deformation by wetting the clogging material [1].
Увлажнение кольматирующего материала в известном способе осуществляется фильтрационным потоком, что не обеспечивает надежность сооружения при сработке водохранилища.Humidification of the clogging material in the known method is carried out by a filtration stream, which does not ensure the reliability of the structure during the discharge of the reservoir.
Целью изобретения является повышение надежности сооружения при многократных сработках водохранилища.The aim of the invention is to increase the reliability of the structure with multiple drawdowns of the reservoir.
Указанная цель достигается тем, что кольматирующий материал увлажняют принудительно, например из резервуаров, установленных на берегах.This goal is achieved by the fact that the clogging material is forcibly moistened, for example, from tanks installed on the banks.
Сущность изобретения состоит в том, что инфильтрация воды в окружающий материал ядра увлажняет его и делает пла- 25 стичным в зоне выше кривой депрессии. При трещинообразовании это обеспечивает самозалечивание ядра с самого начала возникновения микротрещин. ..В случае быстрого раскрытия трещин, например приThe essence of the invention is that the infiltration of water into the surrounding core material moisturizes it and makes it plastic in the zone above the depression curve. With cracking, this ensures self-healing of the nucleus from the very beginning of the occurrence of microcracks. ..In the case of rapid crack opening, for example when
ЕНИЯ МОНОЛИТНОСТИ (ЭКРАНА) ПЛОТИНЫ ПРИ ЕГО ДЕФОРМАЦИЯХ сейсмических воздействиях, частицы кольматирующего материала, увлекаемые водой, способствуют их заделке, не препятствуя дальнейшему проникновению воды в 5 трещину.EONIA MONOLITHICITY (SCREEN) DAMS UNDER ITS DEFORMATIONS Seismic influences, particles of co-forming material, entrained by water, contribute to their closure, without preventing further penetration of water into the 5th crack.
Использование настоящего изобретения позволяет обеспечить монолитность и плотность ядра (экрана) плотины из глинистого грунта при его деформациях, а следо10 вательно, повысить надежность всего сооружения независимо от уровня воды в водохранилище.Using the present invention, it is possible to ensure the solidity and density of the core (screen) of the dam from clay soil during its deformations, and, consequently, to increase the reliability of the entire structure regardless of the water level in the reservoir.
