Информация за проекта

Местоположение: Ingolstadt, Германия

The so-called Audi tunnel, the line of the newly built ICE train connection between Nuremberg and Munich crosses a part of the company premises of the car manufacturer Audi underground. With respect to vibration-sensitive production plants, the idea of a mining-type blasting of the tunnel tube was no option. The construction was carried out with the cut-and-cover construction method instead. After the completion of the diaphragm walls and the bottom below ground, the outer tunnel walls were formed single-sided and concreted against the retaining walls.

Изисквания

  • Mounting of single-sided wall formwork against diaphragm wall concrete
  • Fast and accurate concreting

Информация за клиента

  • Completion of the concreting segments according to schedule
  • PERI tie brackets for efficient mounting of ties for the utilization of brace frames
  • For each brace frame, there were two ties of the DW 26 system in order to safely support high loads (permissible load 2 x 250 kN)

PERI решение

  • The ARGE, the building consortium, used TRIO panel formwork elements and brace frames in the area of the standard cross-section. They were produced especially for the requirements of the project.
  • Designed for a concreting height of 6.48 meters, two movable units were connected with a filler plate for a concreting cycle of 10.20 meters length.
  • At the beginning, the jobsite team moved the formwork units separately, later however, they moved them in one from cycle to cycle with the help of a puller hoist.
  • The maximum height of 9.60 meters was concreted in two steps. Up to a height of 6.55 meters, brace frames and TRIO panel formwork elements were used, and for the second concreting step then TRIO elements on SKS 180 climbing brackets.
