This, I think, is a driving lesson for an articulated boom lifter. Piece of cake, I would think…

The Crowd

The Crowd

Yesterday was the day of the tunnel boring machine: Together with 20,000 other visitors, we had an opportunity to get a good look at the machine which lies hidden deep in a trench cut through the basalt. (The tunnelling will take place in softer clay below the rock.)

In about two years’ time, the machine will be back, re-appearing from behind the artfully decorated disk on the left. In that time it will have cut a tunnel of 2.5km length, surfacing again at Waterview, turned around and drilled a second tunnel on the way back.

About the art:

Te Haerenga Hou, meaning New Journey, is the artwork that has been designed for the Waterview Connection project by Auckland artist Graham Tipene. At 14 metres in diameter, it is approximately the same size as the cutting face of the Tunnel Boring Machine.

It depicts the journey from the Manukau Harbour along the route of what is now State Highway 20, past the volcanoes of Te Ara Pūeru /Māngere, Te Hōpua (Gloucester Park), Maungakiekie (One Tree Hill) and Puketāpapa (Mt Roskill), to the feet of Ōwairaka (Mt Albert). This is where the new tunnels of the Waterview Connection will be built to lead travellers out toward the Waitematā Harbour. The korero (story) of the journey surrounds the lovers Tamaireia and Hinemairangi, the traditions about whom relate to the creation of the many volcanic features around the Auckland region.

Boring, Boring!

Cutting Head, Alice TBM

Cutting Head, Alice TBM

Cranes featured on and off recently on this blog, the reason being the construction of the Waterview Connection, a major tunnelling project for State Highway 20, completing eventually a ring route around Auckland.

Main protagonist in the exercise is the Tunnel Boring Machine (“Alice TBM“), a gigantic beast of 14.5 metres diameter which will chew its way 2.4 km from Owairaka to Waterview and then back again. Engineered by Herrenknecht in Germany, and constructed in China, it is billed as the 10th largest such machine by head diameter. The machine was completely assembled in China, then taken apart and shipped to New Zealand, where it is currently being reassembled.

The image shows the big cutting head of some 300 tonnes in weight being lifted by two cranes from its horizontal position. The big crane on the right will then rotate counterclockwise to lower the head into the pit below (out of sight) where it will be attached to the body of the machine.

A list of largest TBM’s is here.

Tension wil be high

High Tension Cable

High Tension Cable

A high tension cable carrying 22kV to 33kV has been installed between Blockhouse Bay substation and the construction site at State Highway 20, where it will power the Tunnel Boring Machine (going by the name of ‘Alice’). On one of my visits to the site I watched technicians joining cables and one of them explaining proceedings. He also handed me a sample of the cable: over 5cm diameter, with thick dielectric insulation and aluminium conductors of about 4mm diameter (you can count them and let me know the result when you have finished).

The difference between the two views: one cut with a bolt cutter, the other with a saw.

Diesel Power

Looking down into the railway trench at New Lynn station. Engine 4444 just pulling away towards Avondale, the next stop. You can see that the overhead wires for electrification are in place – in a year’s time Diesel engines should be history.

On the wall one can get a glimpse of the decorative panels (by Louise Purvis) that run along the entire length of the station.

One more from the construction site of State Highway 20, by Alan Wood Park, Hendon Avenue. The walkway gets you up close and personal with the big machinery building the temporary road for construction traffic.
