Изобретение относитс  к области гидротехники .This invention relates to the field of hydraulic engineering.

Известны способы создани   дра в плотине из местных материалов путем принудительной подачи холодного воздуха в основание плотины .Methods are known for creating a core in a dam from local materials by forcing cold air to the base of the dam.

Цель изобретени  - ускорение работ по возведению плотины.The purpose of the invention is to accelerate the construction of the dam.

Это достигаетс  тем, что поданный в основание плотииы воздух направл ют через фильтрационный воздухопроницаемый слой, например , из грави , отсыпаемый одиовременно с плотиной.This is achieved in that air supplied to the base of the flesh is directed through a filtration air-permeable layer, for example, from a gravel, poured at the same time as the dam.

Отсыпку сло  производ т в той части плотины , где это требуетс  по технологическому расчету и конструктивным соображени м, предусматривающим созданием мерзлого противофильтрационного  дра плотины к ееLaying of the layer is made in that part of the dam, where it is required by technological calculation and design considerations, involving the creation of a frozen impervious dam core to its

гребшо. При этом охлаждают нижние слои тела плотины и верхние слои ее основани , что способствует падежному смыканию мерзлого  дра плотины с вечномерзлыми грунтами основани , как в стадии строительства, так и при эксплуатации сооружени .combed At the same time, the lower layers of the dam body and the upper layers of its base are cooled, which contributes to the case of closing of the frozen dam core with permafrost soils of the base, both under construction and during operation of the structure.

Пред.мет изобретени Prev Invention

Способ создани  мерзлого  дра в плотине из местных материалов путем принудительной подачи холодного воздуха в основание плотины, отличающийс  тем, что, с целью ускорени  работ по возведению плотины, поданный в основание плотины воздух направл ют через фильтрационный .воздухопроницаемый слой, например, из грави , отсыпаемый одновременно с плотиной.A method of creating a frozen core in a dam of local materials by forcibly supplying cold air to the dam foundation, characterized in that, in order to accelerate the work on the dam construction, the air supplied to the dam foundation is directed through a filtration-air-permeable layer, for example, from gravel, filled simultaneously with the dam.
