Reconstruction of a big navigation lock in České Kopisty

Reconstruction of a big navigation lock in České Kopisty
Within the framework of modernisation of the Labe waterway a complete reconstruction of a big navigation lock in České Kopisty needed to be carried out. The foundation pit was secured and sealed by single-row and double-row cofferdams made of sheet pile walls; the central separating wall was sealed and underpinned by jet grouting. A bottom dredge was carried out in the lower and upper navigation canals and pile sleeves from steel welds were set. The works ?nished with treatment of the banks and their stabilisation with a stone backfill and broken stone paving.
