Liebherr slurry wall cutter takes on Munich’s largest development mission

In an effort to cope extra effectively with the bustling stream of passengers within the internal metropolis, the Deutsche Bahn is constructing a second core line between the stations Laim and Leuchtenbergring. Right here, the three way partnership VE 41 comprised of Implenia and Hochtief, is finishing up slurry wall work utilizing Liebherr gear. 

Excessive calls for

The challenges lie within the giant dimensions of the slurry partitions and the extraordinarily confined area on the development web site. As a result of historic buildings within the speedy environment, an utility with low vibration is critical for the set up of the slurry partitions. On the similar time, it should additionally meet the excessive calls for for compactness and verticality. The contractor discovered the right gear within the brand-new Liebherr slurry wall cutter sort LSC 8-18 L.

The cutter’s excessive weight, excessive cutter body and low centre of gravity present the optimum foundation to realize the mandatory verticality. Most course of security is achieved by means of the complete integration of the verticality measurement within the Liebherr management system. Moreover, 12 independently controllable steering flaps can right the slicing course ought to any potential deviations happen. The precise place of the flaps is displayed in actual time on the monitor within the operator’s cab. In an effort to take care of the confined areas of city development websites, the cutter will be positioned over the chunk utilizing a steady hydraulic turning machine.

The brand new gear from Liebherr cuts its manner by means of 33 cubic metres of soil per hour and requires 8 hours for a main trench. A complete of 108 trenches measuring 1500 x 3200 millimetres with 30 centimetres of overlap have to be put in on the development web site in Munich. 

Along with the cutter, the hydraulic slurry wall seize, sort HSG 5-18, is in operation. It’s also fitted with verticality measurement and a turning machine for the body and is especially used for the preliminary excavation of the trenches.
