Crossing the E20 motorway

 

Skafte A/S has, in cooperation with Fjernvarme Fyn, had another project in the expansion of the district heating network in Odense and surroundings. In this project, the E20 motorway at Ravnejergsgyden had to be crossed by a steered drilling.

A Casaflex (CFL) flexible stainless steel pre-insulated district heating pipe was selected for this task.
The pipe can be laid directly into the ground as a conventional district heating pipe - however, it is safer to use a pressure pipe as a casing for a controlled drilling.

Dimensions and lengths supplied by Skafte A/S:
Dimension: DN80 98 / 182mm
Lengths: 2 x 170m - supplied on drums in diameter of 3.60m and with a width of 1.65m.

The project included a total of loading of drums from block wagons, positioning of the unwinding device, preparation of drilling equipment, pulling of casing 2 x 170m, and subsequent drawing of 2 x 170m Casaflex pipes in casing.

The assignment was completed the same day with the help from Brugg's professional engineers.
