LARGE DIAMETER DYNAMIC PIPE BURSTING FOR SEWER REPLACEMENT

Pubblicato il da

Client: EUROSCAVI Srl – Italy

Year: 2016

What I did: I made the detailed design of the replacement by dynamic pipe bursting of a DN600 (24″) sewer concrete pipe with a DN800 (32″) HDPE pipe; I coordinated all the geological/geotechnical preliminary survey and I also made the detailed design of the bursting-expanding head, tailored shaped to work with a Tracto Technik TAURUS rammer (24″). The expander has an outside diameter of 1000 mm. The soil was sand with coarse to very coarse gravel.

CEMENT MORTAR LINING TECHNOLOGY AT MILANO

Pubblicato il da

Client: Risanamento Condotte Srl – Italy

Year: 2008-2010

What I did: the R&D for the improvement of the Cement Mortar Lining (CML) technology and the detailed design and manufacturing supervision of motorized lining machines.On the application side I made the detailed design of the rehabilitation, by CML, of existing DN1000 (40″) and DN 1200 (48″) steel water mains, for a total length of 3.000 m (9.800 ft), in the City of Milano, Italy. Thanks to CML technology the Client, Metropolitana Milanese Spa, saved more than 80% of construction costs and up to 98% of earth-moving compared to a traditional open-trench replacement.
