DOP Submersible dredge pumps

Tunnel bed prepared using DOP Dredge Pump 200

PROJECT SUMMARY

Location: Aqueduct Bergum, the Netherlands

Period : Q1-2,2016

Product type : DOP200 with leveller head

Contractor : Molhoek B.V.

The DOP200 will reach a max dredging depth of -13 m. Currently the production is some 900 m3/h of solids per working day, delivering the material to a depot nearby.

In the northern Netherlands province of Friesland a new motorway is under construction. One of the civil engineering works required in the project is an aqueduct under the “Princess Margriet Canal”. The building pit of the tunnel has been dug by excavators. As the pit floor is to be completely level to receive the tunnel elements, the DOP200 has cleaned the building pit.

DOP200 clears building pit

The DOP200, doing the cleaning action of all material lost by the excavators, is attached to a pontoon-based excavator. The DOP200 will reach a max dredging depth of -13 m. Currently the production is some 900 m3/h of solids per working day, delivering the material to a depot nearby.

The tunnel elements are prepared on site. Once the building pit is completely level & clean, the elements are positioned and put into place. In October 2016 the new motorway will be finished and open for the public.
