Tunnel boring machine

The "new" U-55 was drilled in Berlin with such a large tunnel boring machine, we decided to visualize this project. @bvg_weilwirdichlieben @weilwirdichlieben @BVG_Kampagne 🚇🚍👨‍👧‍👦💗 More you can see here: www.behance.net/gallery/20377183/ixtract-tunnel-boring-machine-TBM #ixtract #StefanFichtel #Berlin #Infografik #Visualization #Dataviz #VisualStorytelling #storytelling #bvg #weilwirdichlieben #publictransport #WeilWirDichLieben #U55 #Drilling #Underground #Metro #BVG #3D #Rendering

So it's not exactly automotive, but it is a fascinating vehicle – and you'll excuse us if we don't make any puns about how boring it actually is. A portion of Seattle's Alaskan Way Viaduct is being replaced by a deep tunnel, and the machine purpose-built for the job is the world's largest tunnel boring machine (TBM), christened "Bertha." Built by Hitachi Zosen, the 300-foot-long doomsday machine is excavating a 57.5-foot-wide hole for a two-level highway with two lanes in each direction.

The tunnel boring machine (TBM) market is experiencing steady growth due to increased urbanization and the need for transportation infrastructure. TBMs are machines used to excavate tunnels for various purposes such as road and rail networks, water and sewage systems, and underground storage facilities. They are highly efficient compared to traditional excavation methods and can […] The post Exploring the Global Tunnel Boring Machine Market: Industry Analysis and Future Trends appeared ...

The final phase of repairs are being made to get Bertha, the five story-high drilling machine stuck underneath the city of Seattle moving again after grinding to a halt last year after striking an object.

In the last entry, you saw those cool, circular tunnels that will house Manhattan's new 7 Train extension, lined with pre-fab concrete sections. Above is a photo of a similar tunnel in Delhi. Question is, how did they dig and line these things? They use what are called TBMs, or...

A TBM is a massive set of complex equipment assembled together to excavate a tunnel, often called as "Mole". Major components of this Tunnel

Preparing for digging in March.

A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can bore through anything from hard rock to sand. Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.
