The small hydro power station Lovosice-Píšťany is located on the right side of the Lovosice weir (river km 60,125). With its installed capacity of 3,2 MW the hydro lists among one of the largest hydro power stations in our country. Its foundation pit was sheeted with the use of structural monolithic diaphragm walls, simple sheeting walls were designed for the engine room and sheet pile walls were used at inlet and outlet areas. Due to the fact that anchoring under the weir structure was banned, 80cm thick diaphragm wall panels with vertical ribs were carried out in close proximity of the weir pillar. These T-panels are anchored into the bedrock with vertical anchors both diaphragm and sheet piles walls were strapped into the bedrock to reduce groundwater inflow in the foundation pit. Contact points of different structures were sealed up by jet grouted columns.
