Nordhavnsvej Tunnel, Denmark

Nordhavnsvej Tunnel - The formwork carriage has been designed so that trucks can pass through at any time without obstacles. Due to the cramped site conditions, an absolutely essential requirement for the execution.
Nordhavnsvej Tunnel - The slab formwork carriage for the Nordhavnsvej tunnel project consists almost entirely of system components from the Variokit engineering construction kit – and is therefore extremely cost-effective.
Nordhavnsvej Tunnel - Everything from one source: PERI has provided a comprehensive solution. Through the mounted Alu 75 site staircase and Prokit EP 110 side protection, safe conditions have also been created for the construction team when using the access points as well as carrying out slab formwork activities.
Nordhavnsvej Tunnel - The formwork carriage can be raised and lowered by means of the integrated hydraulic system – this results in fast and convenient shuttering and striking. After a short induction phase, the construction team requires only one day to set up the carriage for concreting operations.
Nordhavnsvej Tunnel - The walls of the tunnel entrances are characterized by their special shape. These areas were formed using project-specific girder wall formwork which included GT 24 formwork girders with special lengths.
Nordhavnsvej Tunnel - The new 620 m long Nordhavensvej tunnel is being realized using the cut-and-cover method. The walls are concreted against the up to 25 m deep bore pile wall. Following this, the 80 cm slab is concreted by means of a Variokit slab formwork carriage.
Nordhavnsvej Tunnel - A number of technical buildings are required on the tunnel structure. The requirements include 15° inclined walls, rounded corner areas and a specific tie arrangement which have been met through the use of a customized formwork solution with Vario GT 24 girder wall formwork.

Project data

Location: Copenhagen, Denmark

  • 620 m long tunnel with two rectangular tubes each with two lanes
  • constructed using cut-and-cover, semi-monolithic method (bottom slab, walls and slab one after the other)
  • architecturally attractive tunnel entrances

Requirements

  • approx. 25 m long concreting sections
  • tunnel bottom slab and walls with large-sized panel formwork
  • 2 tunnel tubes each with 9.10 m clear width, realization of a haunch to the middle wall
  • creation of a passageway through the formwork carriage for the site traffic
  • safe access points and working scaffold in all areas
  • minimization of crane use as well as moving possibilities without use of crane for the areas below the railway line in the intersection area of the tunnel and rail traffic

Customer

Joint Venture E. Pihl & Søn A.S. and Ed. Züblin AG

Customer's benefit

  • cost-effective solution for the formwork carriage with more than 90 % rentable system components, with passageway for on-site traffic
  • simple solution which could be quickly implemented and set up
  • load-bearing, larged-sized and movable formwork and scaffolding units for accelerated construction progress

The main reason why we chose PERI was, that we were sure to have a formwork supplier, that can always deliver the material and has the necessary technical know how to design all solutions for this kind of project.

PERI solution

  • 4 VARIOKIT slab formwork carriages each 13.50 m long, coupled together for the realization of the approx. 25 m long concreting sections
  • creation of a passageway for on-site traffic
  • planning of a wall formwork solution for the tunnel walls
  • reinforcement scaffold which can be moved as large units by means of transportation wheels
