GRUNDORAM installs steel pipes in the centre of Bucharest

In the centre of romanian capitol Bucharest two steel pipes have been installed over 35 m length underneath the Mihai Bravu Boulevard. For the construction of several new pedestrian crossings also new bridge piles had to be founded. As part of this the district heating main line has to be relocated. To do so 2 parallel steel pipe strings of 35 m length were installed. Due to the massive traffic volume this could only be done underground using the trenchless TT ramming technology.






Key facts:
Undercrossing of theMihai Bravu Boulevard and a sewer main pipeline
Installation of a steel pipe Ø 1200 mm, length 35 m
Installation of a steel pipe  Ø 1020 mm, length 35 m
Installation depth 5 - 6 m
Executing company: RAPID COMPLEX
GRUNDORAM model: GOLIATH
High-performance pumps were used to pump infilltrating ground water out of the starting pit. Because the ground water level kept rising during installation, an emergency drain pipe Ø 160 PE was installed using the GRUDOPIT mini steerable boring system. The jobsite was executed very quickly to the perfect satisfaction of everybody involved.
