Abstract
Sposób regulowania ilości wody gruntowej usuwanej z obszaru wykopu ograniczonego systemem przegród odcinających (2), pozwalający na kontrolowane obniżanie poziomu wody gruntowej na obszarze wykopu, obejmujący kontrolowane usuwanie wody gruntowej z wnętrza obszaru ograniczonego przegrodami odcinającymi (2) i jej grawitacyjne odprowadzanie do nawadniających studni (3), usytuowanych poza przegrodami odcinającymi (2). Przed rozpoczęciem usuwania wody z obszaru wykopu ograniczonego przegrodami odcinającymi (2) określa się znanymi badaniami hydrogeologicznymi wielkość współczynnika filtracji wody do wewnątrz systemu przegród odcinających (2) oraz wielkość współczynnika chłonności wody na zewnątrz systemu przegród odcinających (2), a także głębokość położenia warstw geologicznych o największej chłonności, na obszarze wewnątrz przegród odcinających (2) teren wykopu wykonuje się co najmniej jedną odwadniającą studnię (1) o głębokości większej niż docelowy poziom zwierciadła (B) wody gruntowej w wykopie, na obszarze na zewnątrz przegród odcinających (2) teren wykopu wykonuje się dla każdej studni odwadniającej (1) co najmniej jedną, a korzystnie co najmniej dwie nawadniające studnie (3), o głębokości odpowiadającej głębokości warstw geologicznych o największej chłonności lub o głębokości odwadniającej studni (1) oraz usuwa się wodę gruntową ze studni odwadniających (1), odprowadzając ją rurami spustowymi (10) poza przegrody (2) do studni nawadniających (3) i grawitacyjnie wprowadza studniami nawadniającymi (3) do wgłębnej warstwy geologicznej o największej chłonności lub do tej samej warstwy geologicznej, z której woda została odprowadzona przez studnię odwadniającą (1).A method of regulating the amount of groundwater removed from the excavation area limited by the system of shut-off partitions (2), which allows controlled lowering of the groundwater level in the excavation area, including the controlled removal of groundwater from the interior of the area bounded by the cut-off partitions (2) and its gravitational drainage to irrigation wells ( 3), located outside the partition walls (2). Prior to the commencement of water removal from the excavation area bounded by shut-off partitions (2), the known hydrogeological tests determine the size of the water filtration coefficient inside the cut-off partition system (2) and the water absorption coefficient outside the cut-off partition system (2), as well as the depth of geological layers with the highest absorbency, at least one drainage well (1) with a depth greater than the target level of the water table (B) of groundwater in the excavation, in the area inside the shut-off partitions (2) in the excavation area, outside the cut-off partitions (2) for each drainage well (1) at least one, and preferably at least two irrigation wells (3), with a depth corresponding to the depth of the geological layers with the highest absorption or depth of drainage well (1) and ground water is removed from the drainage wells (1), discharging it via drain pipes (10) outside the partitions (2) to the irrigation wells (3) and by gravity introducing irrigation wells (3) into the deep geological layer with the highest absorbency or into the same geological layer from which water was drained through a drainage well (1).
