Abstract (en)
[origin: WO2019197402A1] A method for upgrading and/or repairing a dam (1, 30), the dam (1, 30) being provided for damming a reservoir of water (2) and having a dam wall (3) the bottom (4) thereof being founded on a ground (5); whereby said method comprises the following steps: Formation of a support structure (6) on a side (7) of the dam wall (3) facing away from the reservoir of water (2); whereby the support structure (6) defines at least one pressure-tight space (8) being bounded by the dam wall (3); Applying pressure above atmospheric pressure to the pressure-tight space (8), so that the penetration of water into the pressure-tight space (8) through the dam wall (3) is at least minimized. At complete pressure- balance the water-leakages are being stopped. Furthermore, a dam (1, 30) for damming a reservoir of water (2), comprising: a dam wall (3), the bottom (4) thereof being founded on a ground (5); and a support structure (6) being arranged on a side (7) of the dam wall (3) facing away from the reservoir of water (2); whereby the support structure (2) is configured to define at least one pressure-tight space (8) being bounded by the dam wall (3), and wherein pressure above atmospheric pressure is applied to the pressure-tight space (8), so that the penetration of water into the pressure-tight space (8) through the dam wall (3) is minimized, preferably stopped. Any pressure above atmospheric pressure in the pressure-tight space (8) will result in hydraulic support/reduction of forces of the dam-wall (3). The support structure (6) further provides mechanical support and can be combined with a spill-water run-off chute (33) which prevents the near dam downstream river-bed from being eroded in form e.g. of a deep "Plunge-Pool" which may cause structural damage to the dam-wall (3).
