Abstract

1. Способ защиты заглубленных зданий и сооружений от подпорного подтопления грунтовыми водами, заключающийся в том, что формируют под всем сооружением распределительно-фильтрационную песчаную подушку, отличающийся тем, что ее снабжают нагнетательно-промывочной системой, с помощью которой тело подушки очищают от глинистых частиц естественной кольматации промывкой грунтовой водой, имеющей суффозионную скорость фильтрации, которую создают нагнетанием сжатого воздуха под подошву подземной части сооружения.2. Устройство для защиты заглубленных зданий и сооружений от подпорного подтопления грунтовыми водами, содержащее нагнетательно-промывочную систему в виде колонн, установленных вертикально по всей площади подушки квадратной сеткой со стороной квадратов 1500…2000 мм, причем колонны установлены на всю глубину подушки с заглублением в материковый грунт на 100…150 мм и выполнены в нижней части цельными, высотой 250…300 мм с глухим днищем, а выше, до установившегося уровня грунтовых вод, имеют перфорированную поверхность, снабженную сетчатым фильтром, а верхняя часть колонны закрыта герметично фланцевой крышкой с закрепленными в ней патрубком трубопровода сжатого воздуха и вводом в трубопровод канализации промывочной воды, при этом трубопровод сжатого воздуха и трубопровод канализации промывочной воды размещены в лотках над колоннами в их створе порядно.1. A method of protecting buried buildings and structures against backflooding by groundwater, which consists in forming a distribution and filtration sand cushion under the entire structure, characterized in that it is provided with a pressure-flushing system, by which the cushion body is cleaned of clay particles by natural mudding by washing with ground water having a suffusion filtration rate, which is created by injecting compressed air under the sole of the underground part of the structure. 2. A device for protecting buried buildings and structures against backwater flooding by groundwater, containing a pressure-flushing system in the form of columns installed vertically over the entire area of the pillow with a square grid with a square side of 1500 ... 2000 mm, and the columns are installed to the entire depth of the pillow with a burial in the mainland soil by 100 ... 150 mm and made in the lower part solid, with a height of 250 ... 300 mm with a blind bottom, and above, to an established groundwater level, have a perforated surface equipped with a strainer and the upper part of the column is closed by a hermetically flanged lid with a compressed air pipe fitting in it and a rinse water inlet to the sewer pipe, while the compressed air pipe and the wash water sewage pipe are placed in the trays above the columns in their alignment in order.
