What is pile head cutting?

We speak of pile head cutting, when we cut off pile caps or screw piles, so that the rebar is revealed.

Exposing rebar cages Erkat rotary drum cutters on a job site near the European XFEL X-ray Laser facility in Hamburg This was a project carried out by WIWA Wilko Wagner using two Erkat rotary drum cutters. They were used for the installation of retaining walls to depths of 15 to 16m in sandy ground conditions. An ER 650 mounted on a CAT 323D was used to expose the internal and external surfaces of the upper parts of the re-enforcement cage. The smaller ER 250 was mounted on a Vio 70 and was used for those areas where the ER 650 was too large. In this application, success depended to a large extent on the visual judgement and the skill of the excavator operator as it was important not to damage the steel re-enforcing bars while removing the material around the cage. Hydraulic breakers would not have been suitable for this type of work due to the high levels of vibration they produce. The drum cutters were used for a period of approx. 2 weeks.

Profiling pile walls An ERC 650 used to profiling work on a piled wall. With continuous, infinite rotation, the ERC 650 can reach all the required profiling positions with excessive movement of the excavator. This saves up to 30 percent of tracking time for the excavator.
