If nah Nigeria Govt want to do this kind project now, nah hunger people here will be shouting nah bridges they want do when they are hungry.
Hunger ki u there.

Great100000:
Jinan, a city of 9.4 million people and the capital of Shandong Province in East China, has made world headlines. Crews working there have completed the monumental task of building the world's largest-diameter underwater shield tunnel.

Using the largest available tunnel boring machine (TBM) on Earth, the China Railway 14th Bureau Group Co., Ltd. is still excavating the main section of the 3.6-mile (5,755 m) tunnel. The 2-mile (3,290-m) section of underwater shield segments, however, is complete.

This section is a colossal 55.8 ft (17 m) in diameter and consists of 500 pipe rings of underwater shielding, making it the largest-diameter tunnel of its kind anywhere in the world.

For comparison, the Channel Tunnel that connects the UK and France has three tunnels, two of which are the public rail tunnels with a diameter of about 25 ft (7.6 m) ... though it is significantly longer, at 31.4 miles (50.5 km).

The Jinan Huanggang tunnel will feature six lanes of travel in both directions in a double-decker configuration, with a 60 km/h (37 mph) speed limit. It will be a crucial north-south passage across China's second-longest river, the Yellow River, enhancing connectivity between Jinan's main urban area and what is described as "the starting area for the transformation of new and old kinetic energy."

Aside from setting a world record for the tunnel's sheer size, the 14th Bureau Group also set a world record for completion time for such a vast undertaking.

Crews began tunneling on September 1st, 2024, and while the entirety of the tunnel hasn't yet been completed, the underwater shielding portion has. It was accomplished in a mere 110 days. The Shanhe shield machine had a daily advancement rate of 52.5 to 59 ft (16 to 18 m), setting a new world record for 17-meter-class shield construction.

The boring machine in question is the Herrenknecht "Shanhe" Shield Machine, a mixshield tunnel boring machine boasting a 57.4-ft (17.5-m) excavation diameter – roughly 5 stories tall. The cutterhead driver has 7,510 hp (5,600 kW) and about 25,827,209 lb-ft (35,017 kNm) of torque. Yes, nearly 26 million lb-ft of electric motors and hydraulic power.

It's built to operate and withstand up to 7.5 bar of pressure (that's 7.5 times normal atmospheric pressure at sea level). The excavation chamber on the business end of the Shanhe can handle up to 15 bar using a specialized automatic air cushion to balance pressure, maintain stability, and prevent collapse or flooding.

The cutting wheel is equipped with a flushing system to help prevent clogging. It also has a telescopic camera system in the excavation chamber to monitor the cutting bits and tunnel face. This reduces the need for hyperbaric intervention by maintenance workers, which is time-consuming and dangerous.

If you want to get a Shanhe for yourself, it'll likely set you back at least US$80 million or so. This figure is based on the Santa Clara Valley Transportation Authority (VTA) in the US having shelled out a cool $76 million a 16.46-meter diameter Herrenknecht TBM.

The Jinan Huanggang Road Yellow River Crossing Tunnel is scheduled for completion sometime in late 2025.

China China!! In Trump's mimics voice. Una well done o.

xpressionx:
China is by far smarter than Russia.
I am sure China will never agree to fight any war ,they are just interested in economic and technological dominance.

North Korea and Russia will rush quickly into destruction in few years time.

Anything can happen with Taiwan at any moment, stop yapping nonsense

nairalee:
The pace with which China is developing, it's obvious democracy is not the only formula to progress. If Nigeria knows that democracy is not working and this federation is not feasible pls we must not copy the West hook line and stinker

It is not about democracy or autocracy, it is about killing the corruption and embracing patriotism

Advanced development without the interference of religious servitude.
Surely, religion has made many Nigerians morons.

pbetu:
China and technology be like 5&6

Now, they're testing drones that travel at Marc 7 or so, working on guiding their hypersonic missiles with 6G technology

Who dies in water

That’s what I keep telling people. But Russian bots like quelme won’t see reasons

Western ass licker, you go wail tire. Did the Russians complain to you?

Killing corruption in our own system of democracy is very difficult because the system is already rigged and following the right channels can be very cumbersome and time consuming

PrepNEWYEAR:
Nigeria president is negotiating the course that is qualified for loan 🤣🤣


Bastard nation with daft citizens

Do you know the amount of fund requirements of these projects? Is not what any individual can do.

Nation Nigeria lacks the vision in infrastructure, so what do you want Nigerian engineers to do?

Urheadmaster:
In Nigeria we are still celebrating the completion of 20 KM expressway by the government

You mean the ones that they will start budgeting to repair less than 2 years.

Biafra is the only hope of Africa when it comes to technology is quite unfortunate that are they are under Nigeria boundage

And China is winning!

They have even taken on the role of the world bank and IMF, lending money to countries for developmental projects and executing same. In order words, they build your projects with their own money.

The down side is that China is a ruthless country. I have worked with them and know how they think.

By the time the details and implications of the railway and other projects they did for Nigeria become public, I'm sure our response will be 'Oh God!'

Grounding of the presidential aircraft by a small, nameless Chinese company which had a bone to pick with Ogun State is just the beginning of their strength and ruthlessness.

The biggest projects in Nigeria are being done by CCECC which is backed by the none other than Beijing itself.

You’re not just stupid, you’re not just dumb but also myopic. Go back to kindergarten and learn some good English 😂 😂

HenryWilliams:


Never to come back.
A pure shame..
China and Nigeria were at par 45 years ago.
Dubai was a desert in the 60s.
Singapore was a swampy wetland in the 60s.
Malaysia was a sleepy dull sweaty country in the 60s.
Where was the UAE in the 60s? full of desert sand and Bedouin
Where are they now?
Compare to Nigeria..
You will weep and cry .

Did you support tinubu

😂 Honestly, you keep exposing yourself. Anyone who makes statements like l “I will feed you and your family” is usually a hungry soul who just brags. The real big boys don’t make a sound.

I roped you in and you fell into my trap to expose your dim witted self. 😂 😂 little man with little mindset.

That’s not true. The US has a fail safe way of always rebooting itself to prevent such collapse.
