TBM Wyspiarka gets closer to Wolin Island!

03/08/2021

TBM Wyspiarka has already bored 970 m under the Swina river for the Swinoujscie tunnel on the S3 Swinoujscie-Troszyn expressway: in about 30 m the TBM will cover the entire riverbed of the Swina Strait, only 500 m more and the machine will finish drilling the tunnel completely. The preparatory works are underway at the receiving chamber on Wolin Island, where the TBM arrival is estimated for in September and where it will be dismantled

In addition other works related to the construction of a new road in Świnoujście are in progress:

On the island of Usedom at the starting chamber, sealing and washing of diaphragm walls continues. The structure is sealed around the area of the ramp

Finishing works of the ramp structure are also being carried out. Prefabrication of the temporary stiffening structure for the emergency exits in the tunnel is also in progress.

At the STP (Slurry Treatment Plant) plant, the excavated material is being separated from the drilling fluid: once extracted by the TBM it goes to the plant through pipelines and then -after cleaning - it is transported to the silting field - The separated drilling fluid is then recycled.

The reconstruction and construction of the utilities network and road infrastructure on both islands is ongoing.
