A powerful Liebherr rotary piling rig was able to carry out a tricky construction project in Rorschach next to a key road link
Specialist contractor 2552 Implenia Bau recently carried out some piling work for main contractor 3317 Keller Bauunternehmung on a project at Rorsach in Switzerland.
 The work involved the construction of a secant pile wall as part of a project to build the Raiffeisenbank, located next to a key road. The company opted to use a 718 Liebherr LB28 piling rig equipped with a DBA200 rotary head. The specifications required the installation of 3,000 linear metres of piles to form a secant drilled pile wall within 10 weeks. The 225 piles measure from 12-16m with diameters of 700mm. The whole construction project lasted 4 months in total. The secant pile wall was built using a DBA200 double rotary head delivering a torque of up to 200kNm at the drill casing and 100kNm at the auger. The drill casing and auger were drilled out in one working cycle, with concreting carried out as the drilling equipment was removed and the reinforcement placed later.
