Small hydro power plant Steti – foundation pit securing and plant construction

The task of the special foundation work was to ensure a watertight construction pit for the entire building Štětí small hydropower plants (HPP). Temporary sheeting river side works in the length of about 360 m was conducted from sheet pile walls and coffer-dams. Inlet and outlet object was secured by permanent anchored diaphragm and secant pile walls. Custom object SHPP is lagged with diaphragm and secant pile walls with temporary anchors. The excavation reached a depth of 18 meters from the original terrain (ie. About 17 m below the operating level of the Elbe). A separate part of the project consisted of securing of the underground part of the power plant. It is a set of technologies to reduce the inflow of artesian water to the construction pit in areas with the deepest trench, including anchoring the building foundation slab. Together with shoring pits formed these measures ensure a consistent concept of the underground part of constructions excavation (sealing perimeter grouting, sealing grouting under the bottom with reinforcement, drainage wells).
