Progress in Small Diameter Tunnelling: Challenges and Technology
Abstract: Small diameter tunnels are constructed for a large variety of applications. As safety aspects in mechanized tunnelling have gained more and more importance during the recent years, unmanned procedures like pipe jacking have taken over in the smaller diameters. It is nowadays a complementary tunnelling method in the diameter range of up to four meters, formerly covered by segmental lining TBMs....

Shaft and tunnel construction for deep sewer systems
Abstract: With a growing world population and increasing urbanization, volumes of sewage are rising especially in large cities, which require larger capacities in sewage transport and treatment. The systems built decades ago need to be modernized, extended or replaced to ensure efficient and sustainable wastewater management.The first large-scale Deep Tunnel Sewerage System (DTSS) was installed in 2008...
