Slurry wall cutter
Hydromills are used for very deep trenches and, above all, for very hard building ground. Unlike the grab a hydromill works continuously during excavation. With the help of cutting wheels the building ground is broken up and crushed. A pump inside the hydromill creates an upward flushing circuit out of the trench via hose lines. The loosened cuttings can so be conveyed out of the trench with the support fluid that is pumped to the surface. Thus contaminated support fluid is then cleaned in a treatment plant and fed into the trench again.
Slurry wall production using cutting technique
1. Cutting of the second part of a long, three-part primary trench
2. Cutting of the third part
3. Excavation of the short secondary trench between two long primary trenches
Steering flaps
Hydromills are usually fitted with steering flaps on the cutting frame. These serve to align the hydromill inside the trench.
Continuous excavation
The cutting technique enables a continuous excavation. Therefore the hydromill is inserted only once in the suspension-supported trench.
Hydraulic supply
The hydromill can be driven by the on-board hydraulic system of the powerful Liebherr duty cycle crawler crane.
Enormous trench depths
With a hydromill enormous trench depths of up to 100 metres can be achieved.
Cut-off walls
Cut-off walls are frequently installed using the single phase method for sealing off against groundwater. Here you see the core sealing of a dam.
