China helps world build magnificent engineering projects

Big challenge in desert

A water recycling project is under construction by Chinese engineers in Jazan Economic City, Saudi Arabia.

As the most important infrastructure project for the local community, the system presents a huge challenge for Chinese constructors.

With a 40-meter-wide casting area and just a single parking space for the pump truck on only one side, the arm of the truck has to extend at least 40 meters horizontally, which puts great stress on it.

The pressure generated by the horizontal reach is 3-4 times higher than that in a vertical reach, thus the arm must be made of specially fabricated high-strength steel.

China is one of four countries in the world that is able to make such pump trucks with such high-strength steel. Thanks to the steel forged back in China, the project has been going smoothly.

High-strength steel is a development trend of the international engineering machinery industry, and China’s products have reached world-class level.

Kuala Lumpur’s highest skyscraper

A new skyscraper under construction in Kuala Lumpur will set a new record as Malaysia’s highest building. With a height of 438.2 meters, it is also the highest building built by China in a foreign country.

An integrated hydraumatic lifting platform at the construction site has offered enormous help for the project. Developed by China, it has a bearing capacity of 50 tons and is able to load all the construction materials needed for one floor at one stroke.

The platform is a necessary facility for super high-rise buildings. Construction materials are loaded in the upper floor, and the workers stay in the lower part for construction.

Hydraumatic devices used to be a weakness of Chinese construction, but now the China-developed platform has become a world-class facility. Thanks to the technology, the construction of each floor only takes three days.

“Centenary railway” stretching on grassland of East Africa

Over 24 million tons of materials are being transported on the fertile grassland of East Africa each year.

It is a transportation stronghold of the region, but is still using century-old rail tracks constructed by the UK, on which the trains can only travel at 30 kilometers per hour.

Now, China is constructing a new railway on the continent, the first one built by Chinese in a foreign country in accordance with Chinese specifications.

The railway, connecting the port city of Mombasa and Kenya's capital city Nairobi, has a total length of 480 kilometers.

It only took less than three years for Chinese to finish the construction, the largest infrastructure project of Kenya in 100 years.

The train is able to run four times faster than the previous train, but the ticket price is less than half of the local bus service.

The Mombasa–Nairobi Standard Gauge Railway is making Kenya into a more efficient trade channel of East Africa.

Record-breaking pile pounded into river of Bangladesh

Dacca, capital of Bangladesh, where 15 million people live, is one of the most jammed cities in the world. Transportation is the biggest issue here.

The Padma River that crosses the city is the water of life for local residents, but also a hindrance of the country’s economy as the north-south divide.

Wherry is the only means of transportation that links Dacca with the two provinces and 21 districts in the south. Though the boats depart every two minutes, they still fail to meet the demand. In addition, the service can be interrupted by rainstorms.

Chinese engineers are constructing a six-kilometer cross-river bridge to solve the problem. After completion, the bridge will not only connect the north and south of Bangladesh, but also serve as a significant path of the country that leads to China, Myanmar, and India.

What is amazing about this bridge is that the world’s longest and heaviest steel pile, which has a length of 120 meters, has been driven into the soft river bed of Padma.

The Chinese team offered a stunning plan: Divide the pile into two parts. It was a challenge that even once puzzled bridge masters in the US, Japan, and South Korea.

There is no crane in the world that is able to lift a 120-meter steel structure, and no one has ever successfully divided a pile into two parts.

However, the Chinese team has turned theory into reality. Three workers welded over nine hours on a 20-meter-high platform and successfully integrated the two parts. And the welding joint, with a perimeter of 10 meters, has stood the test of the pounding of the pile driver.

It is a new world record created by 600 Chinese engineers and technicians.
