Construction of a waste-water channel in Belgrade with 1500mm diameter
Ferbild d.o.o., Belgrade
Laying of pipes with 1500mm diameter at a depth of 8m. Proximity to the Danube means that groundwater occurs at only 3m depth. Accordingly, the construction site was 5m below the groundwater level along its entire length. Since the ground contains a high proportion of grit, difficulties were encountered in lowering the groundwater.
12 wells sunk to depths of up to 25m were drilled parallel to the new canal. At this depth the ground consists of shingle and groundwater could be pumped with ease. 15 Tsurumi pumps were used, of types KTZ611,KTZ35.5, KTZ22.2, KTVE35.5 and LH615.
