preface

All industries in China are developing rapidly, with infrastructure being the fastest-growing sector. China's infrastructure level is renowned internationally and is also endowed withInfrastructure DemonThe title of.

And China's infrastructure continues to surpass itself,A multinational infrastructure project has once again set a new recordMake the world stand out.

At the beginning, experts from various countries shook their heads about the Nile River infrastructure project, and China completed it,cut offThe world's longest river, the Nile.

Impossible, absolutely impossible!

This project is to build a dam on the Nile River, which sounds easy, but in realityDifficulties abound.

For reasons such as its own economic development, Sudan, a country in the Nile Basin, is building a dam. However, African countries generallyPoor and underdeveloped countriesIf we can't build it ourselves, we can only do it internationallyBidding.

Although the African region is economically underdeveloped,But rare and non renewable natural resources such as oil and minerals are extremely abundant.

Therefore, at first, various developed countries competed to sign up for contracting, but after experts conducted on-site inspections, they all signed up againdrum-beating announcing the adjournment of court.

With a total length of about 9230 meters, the Merowe Dam is the longest dam in the world. The longest Three Gorges Dam in China is only 2308 meters. In terms of length, the Three Gorges Dam and Merowe Dam can be described as.

Merowe Dam has a total of 10 generating units, with a single unit capacity of 125000 kilowatts, and the total generating capacity is1250 MW.22400 MW.

Although the power generation is only a fraction of the Three Gorges Dam, it is also sufficient for Sudan,.

The Nile originates fromEquatorial rainy zoneThe water is abundant, but after flowing out of the source area,.

.Raise the water level of the Nile River.

124.

However, the reason why.Natural climate.

The Merowe Dam is located in a semi desert area,The construction conditions are extremely harsh.Life threatening.

And as a super large volumeConcrete engineeringHighly influenced by external structural and geological constraints, which can lead to dams.

Moreover, due to the semi desert regionLarge temperature difference between day and nightWill cause internal damage to the concreteCracking due to huge internal tensile stress.

In addition, the arid climate environment can also cause concrete surfaces toSignificant increase in water loss..

So, how did the Chinese engineering team overcome this huge difficulty?

In terms of the most fundamental material issue, China has used domestically developedFirst, we solved the problem ofConcrete cracking.

Secondly, the Chinese team has made every effort to flexibly apply the engineering experience developed and constructed in China, through systematic computer simulation and meticulous moisturizing maintenance,.

And for exampleThe diversion bottom hole and other special parts of the flood discharge dam section make concrete more sensitive to temperature changes.Targeted local reinforcement.

The construction of the Merowe Dam is undoubtedly a big project,Nature consumes a great deal of various materials.

However, SudanWeak industrial foundation and extreme shortage of materials.

However, the local transportation conditions are extremely backward, which can be described asBe stretched to the limit.

In railway transportation, there is only one route from the port to the construction siteMore than a hundred years ago, the meter gauge railway..

And the equipment at the port is also very outdated, and the management is also very chaotic, with slow loading and unloading speeds,The ship needs to wait at the anchorage for a week before it can safely dock.

As for road transportation, it is even worse due to a shortage of materials,.

In order not to delay the construction period, the Chinese engineering team has developed and implemented a unifiedMaterial guarantee system.Ensure sufficient lead time.

Due to the lack of effective port management, the Chinese team has deployed additional staff to Sudanese ports and establishedSudan Port OfficeEffectively supervise customs clearance and transportation work,.

Due to the lack of local transportation resources,The Chinese team directly purchased transportation vehicles in China.

The construction of this huge Merowe Dam is hard to count, but in front of the Chinese engineering team, all these difficulties have been overcome, and China's infrastructure strength is once again.

Since it's so difficult, why is SudanAt all costsHow about building the Merowe Dam?

Why Sudan Built Dams

The budget required to build the Merowe Dam is up to$1.5 billionAnd the GDP of Sudan at that timeOnly $17.63 billionThis major project can be said to be a cost to SudanNational strength.

The reason why poor Sudan is willing to build dams at a high cost is becauseSudan, Egypt, and EthiopiaThese three countries in the Nile BasinGratitude, Resentment, and Resentment.

In the second half of the 19th century, British colonizers set foot on Egyptian land. In order to profit from the colonies, Britain renovated Egypt's water conservancy facilities and built themAswan DamAt that time.

But the British colonizers were still unsatisfied,The neighboring Sudan has fertile land and is extremely suitable for cotton cultivation.

The colonizers once again entered Sudan, intending to develop water conservancy facilities in the country,But was sternly rejected by EgyptBecause Sudan is located in the middle reaches of the Nile River,.

Time passed and after Egypt gained independence, it was signed with Britain in 1929Nile Water Resource Allocation AgreementThe agreement states that Egypt can use 48 billion cubic meters of water annually, andSudan is only allowed to use 4 billion cubic meters.

Due to Sudan's suitability for cotton cultivation,The local economy heavily relies on the cotton textile industry and agricultureAmong them, agriculture accounts for over 45% of GDP, and cotton cultivation also requires water sources. This agreement is equivalent to blocking Sudan'sEconomic lifeline.

That's why SudanNational strengthThe construction of the Merowe Dam,.

There are also reasons for Ethiopia, a country located in the upper reaches of the Nile River, which is alsoLeading by agriculture.

7406450.

.In order to fight for interests, Sudan took the lead and built the Merowe Dam, which also played a role in other two countries.

However, Sudan.

CoincidentallyChina's level in infrastructure is world-renownedMany infrastructure projects in the world are..

Therefore, the complementarity between the Chinese and African economies is gradually becoming prominent, and the economies of the two regions are becoming increasingly close and indispensable to each other.

epilogue

2013..

6China's infrastructure can be described as climbing over a mountain and then rising over a mountain, proving to the world the magnificent strength of China's infrastructure!
