The job definition
After the dismantling of a temporary bridge, the concreted and jacketed steel pipes should now be dismantled.
The steel sheath of the pipe was exposed by protruding or sawing out the concrete casing with a thickness of approx. 15 cm.
This was now burnt out at a height of about 30cm. After this, a core hole with a diameter of 180mm through the concrete core is applied. After the liberation and burning of the monolithic iron in the concrete core, the core was broken with the aid of the core bore and a 3,000 bar press and the pile was subsequently successfully recovered.
