hiDCon®- anchor and foundation elements
The highly deformable concrete of the hiDCon beam elements for the shotcrete shell is also suitable as anchor or foundation element. Like the beam elements, the anchor and foundation elements allow controlled deformations at a defined load level.
Example of the Chienberg road tunnel heave zone
The problem of heave was successfully solved with hiDCon anchor elements and hiDCon foundation elements. The elegant solution came from the inventor of the hiDCon elements Prof. Kalman Kovari. The realised extension has the following advantages:
- Accessible crumple zone
- Maintenance without restrictions in tunnel operation
- Elements can be individually replaced
