Airport Frankfurt

Pipe Jacking under "Runway West"

As part of the expansion of the airport “Frankfurt /Main”, new drainage systems are necessary or need to be extended. SONNTAG is involved in 2 projects in the apron area of Frankfurt Airport:

Project 1: Consortium “Drainage collectors”

For the drainage of the rain water stored in different storage basins into the River Main, pressure pipes must be built. In areas with constant slopes, the supply pipes to these basins can be constructed as gravitation sewers. To cross “Runway 18 West” and taxiways, which are still in service, pipe jacking in the dimensions 1.40 m and 1.80 m are required.

Project 2: Main collector under the taxiways

A main collector is required for the drainage of the new shipyard apron and the runway extension. SONNTAG will implement this order and install 500 m of ND 1.30 m and ND 1.80 m as open constructions and 1.175 m ND 1.80 m by means of microtunnelling.

Altogether, approx. 6,000 m of pipe jacking with nominal diameters of 1.40 m and 1.80 m were constructed in a record time of 5.5 months.
