House access Wettingen
Underground Mining Special projects
Jäger is currently constructing access to a house for a private building owner in Wettingen (Canton Aargau) in Switzerland. An access gallery and shaft are being excavated. Subsequently, a lift will be installed in the shaft which leads directly to the house.
The 40 m access gallery is being driven with an excavation cross-section of about 8 m² as loose stone advance in lower freshwater molasse (soft marl and hard sandstone). The following 17 m shaft with a diameter of 3.50 m will be sunk from above.
The building site is in the middle of a residential area, which is why great attention is being paid to low emission work.
