Project information for the period July to November 2021.

These are the planned activities, but of course there is a risk of changes, mainly due to uncertain ground conditions and other unforeseen events.

 

July 2021:

  • Extension of sheet piles and strengthening by injections. High level of disturbing noise.
  • Drilling of casing. High level of disturbing noise.
  • Mounting of beams and jack posts. Low level of disturbing noise.

August 2021:

  • Test pumping. Low level of disturbing noise.
  • Excavation. Low level of disturbing noise.
  • Demolition of the remaining basement foundation. Medium level of disturbing noise.
  • Mounting of beams and jack posts. Low level of disturbing noise.

September 2021:

  • Excavation. Low level of disturbing noise.

October 2021:

  • Excavation. Low level of disturbing noise.
  • Demolition of the remaining basement foundation. Medium level of disturbing noise.
  • Mounting of beams and jack posts. Low level of disturbing noise.

November 2021:

  • Excavation. Low level of disturbing noise
  • Mounting of beams and jack posts. Low level of disturbing noise.

Explanation of technical terms:

  • Curtain injection is a method used to seal rock in order to avoid uncontrolled groundwater subsidence or leakage into rock shafts. Simplified, this means that holes are drilled in the rock, then the rock's natural fracture system is injected with a cement mortar for a certain time and with a certain pressure. The method seals the sides of the shaft.
    Higher risk of noise.
  • Floor cement injection is done in the same way as curtain injection. The difference is that curtain injection is vertical and floor cement injection is horizontal. The result of these two injektions is a completely tight shaft.
    Higher risk of noise.
  • Stud drilling means that steel studs are drilled down inside the set sheet piles so that they do not slide off the rock but stand securely.
    Higher risk of noise.
  • Shaft, beams and jack posts: The beams is welded to the sheet pile walls. A jack post (a steel post placed perpendicular to the sheet pile walls on opposite sides of the shaft) is mounted on this to prevent the sheet pile walls from falling inwards. When this is done, we excavate about 3 meters before we assemble a new beam level. There are beam levels down to the rock.
    Less risk of noise.
