Berlin mode of construction

Berlin mode of construction

The Berlin mode of construction is based on the consistent application of steered microtunnelling for both main sewers and house connections from cylindrical start and target shafts. The shafts sunk for the micro-tunnelling of the main sewers are also used as the starting points for the driving of the houseconnections.

The latter are driven to the different properties in star form. On the completion of all microtunnelling work, the start and target shafts are converted into inspection manholes. In addition to offering economic advantages in terms of construction, the execution of the house connections to the inspection manholes in straight lines offers many operating advantages such as the ease of cleaning and the checking of lines.
