The Hong Kong Zhuhai Macao Bridge has been built, why is it so difficult to build an aircraft carrie

An aircraft carrier is a complex combat system, but it is not just a big ship. Without a certain amount of experience and technical accumulation, money alone may not necessarily be able to play. It is not easy to build it, and it is not easy to give full play to the overall efficiency of its system, which is not the effort to build a bridge in three or five years.

Think about the leaky aircraft carriers of the old navy Britain, think about the small aircraft carriers of France that ran away from the propellers, and think about the large surplus of American aircraft carriers, and the construction of a new aircraft carrier every few years, and you know how difficult it is to maintain the ability to build and use aircraft carriers.

Building a bridge does not require so many parts, does not need so much mechanical equipment, and does not need to consider the power factor or the sea condition, and the super-large and super-thick overall aircraft carrier deck is not something that conventional manufacturers can manufacture! Therefore, the manufacture of each aircraft carrier is almost a national effort!

Many people don't understand why it is difficult to build aircraft carriers, I am afraid that aircraft carriers during World War II can be dumplings in batches and can be modified with other ships, so there is this impression flow.

It is indeed not difficult for modern countries that can build large ships to build an aircraft carrier during World War II, and many people may feel that compared to their respective eras, building aircraft carriers now is no different from building aircraft carriers 70 years ago.

But the truth is that the difference is too great. The most difficult thing in the technical threshold of modern aircraft carriers is carrier-based aircraft.

Carrier-based aircraft are the core combat power of aircraft carriers, and aircraft carriers are nothing without advanced carrier-based aircraft. This is not only because it is difficult to build carrier-based aircraft, but also because in order to ensure the combat effectiveness of carrier-based aircraft, aircraft carriers need a complete set of outrageously complex systems.

Aircraft carriers require a lot of technology.

Airstrip. **。

Cabins, etc.

Aircraft carriers are already available in our country.

Reasons: 1. The predecessor of the Hong Kong-Zhuhai-Macao Bridge was the Lingdingyang Bridge in the original planning. In the early 80s of the 20th century, although the land transportation links between Hong Kong, Macao and Chinese mainland were constantly improved, the transportation links between Hong Kong and the west bank of the Pearl River Delta were limited by the Lingding Ocean.

2. At the end of the 90s of the same century, affected by the Asian financial crisis, the Hong Kong Special Administrative Region believed that it was necessary to build a cross-sea passage connecting Hong Kong, Zhuhai and Macao as soon as possible, so as to give full play to the advantages of Hong Kong and Macao and find new economic growth points.

The main bridge section starts from Sanshi Bay in the northwest of Lantau Island, Islands District, New Territories, Hong Kong, connects to Hong Kong Port, passes through Hong Kong waters, and passes through the north side of the 23dy anchorage to the west through the Tonggu Channel, Lingding West Channel, Qingzhou Channel, and Jiuzhou Channel at the Pearl River Estuary, passing through the southeast of Gongbei Bay in Zhuhai and ending at the artificial island of Zhuhai and Macao Port.

The reason for the construction of the Hong Kong-Zhuhai-Macao Bridge is to promote the economic development of the three cities on the west bank of the Pearl River Delta (Zhuhai, Zhongshan and Jiangmen) and promote the development of their service and manufacturing industries.

The successful construction of the Hong Kong-Zhuhai-Macao Bridge is also of great significance and purpose to our country, and the first of the construction of the Hong Kong-Zhuhai-Macao Bridge is to activate the economy, because the bending economy of Hong Kong, Macau, Zhuhai, Shenzhen, including Guangzhou will definitely rise to a new height. The second is the successful breakthrough of the bridge, so that the passage distance of Zhuhai, Hong Kong and Macao has been greatly shortened, a bridge connecting the two sides of the strait and the three places in the future will completely realize the one-hour living circle within the bend, and people who work in Hong Kong can live in Zhuhai, Longtan and other places.

This also greatly solves the livelihood problems of the bottom of Hong Kong. In the end, he will bring the hearts of the people of the three places closer, and we all know that because of the "one country, two systems", the distance between the hearts and minds of the three places is still slightly estranged. Now that the Hong Kong-Zhuhai-Macao Bridge has been successfully constructed, it is bound to shorten the distance between the hearts of the people of the three places.

So that the estrangement no longer exists.

Overall layout

The Hong Kong-Zhuhai-Macao Bridge consists of three navigable bridges, one undersea tunnel, four artificial islands and connecting bridges and tunnels, non-navigable continuous beam bridges in deep and shallow water areas, and land links between Hong Kong, Zhuhai and Macao. Among them, the three navigable bridges from east to west are Qingzhou Waterway Bridge, Jianghai Direct Ship Waterway Bridge and Jiuzhou Waterway Bridge.

The Cross Harbour Tunnel is located between Lantau Island and the Qingzhou Channel Bridge in Hong Kong, connecting other sections of the bridge through the east-west artificial islands. The non-navigable continuous beam bridges in the deep and shallow water areas are located in the waters near Hong Kong and Zhuhai respectively. The three ports and their artificial islands are located near the approach bridges at both ends, and are connected to the surrounding major highways by connecting lines.

1. Hong Kong may be further isolated by Guangzhou and Shenzhen, the two ends of the Shenzhen-Zhongshan Corridor are Shenzhen Bao'an and Zhongshan People's Town, and the bridge in Guangzhou to build the Nansha Free Trade Zone also has exports, the middle of the Pearl River Delta, the west bank, the east coast are connected, which is equivalent to Guangzhou, Shenzhen and the three cities formed an interest group, the key is to fundamentally solve the problem of traffic bottlenecks in the Pearl River Delta, and there are no restrictions on mainland vehicles, and it is very likely that there will be Guangzhou, Shenzhen and China to isolate Hong Kong, Zhuhai and Macao.

2. It does not bring direct convenience to ordinary residents in various cities in Guangdong, and the vehicles that can pass through the bridge for a fee mainly include vehicles with license plates from Guangdong and Hong Kong, vehicles with license plates from Hong Kong and Macao, single-plate vehicles with Hong Kong nationality (with Macao quotas), vehicles for one-time quota applications, and other vehicles that can pass through the Hong Kong-Zhuhai-Macao Bridge negotiated by Guangdong, Hong Kong and Macao. The mainland license plate is not allowed to go on the bridge, that is, the civil function of this bridge is only for Hong Kong and Macao car owners, so it can become a cross-century project that is basically unrelated to mainland vehicles.

The reasons for the construction of the Hong Kong-Zhuhai-Macao Bridge are:

1. Make the transportation from Hong Kong to the mainland more convenient.

2. Give better play to the advantages of Hong Kong and Macao and further develop the economy.

3. It is conducive to cultural exchanges and economic and trade exchanges in various places.

4. The construction of the Guangdong-Hong Kong-Macao Greater Bay Area can be promoted, so that the inland and Hong Kong and Macao exchanges will be closer.

Significance of the construction of the Hong Kong-Zhuhai-Macao Bridge:

1. It is a strategic part of China's plan to build a super bay area.

The Hong Kong-Zhuhai-Macao Bridge is a national project, an important weapon of the country, a business card of China, the pinnacle of the history of bridge construction in the world, a concentrated display of China's strength, and the backbone of the Guangdong-Hong Kong-Macao Greater Bay Area, and a strategic part of China's plan to build a super bay area.

2. It reflects China's development ideas.

The Austrian, Hong Kong and Macao Greater Bay Area is an important national development strategy, and the two special zones and nine cities need to be equipped with comprehensive transportation hardware facilities for coordinated development.

3. It reflects the country's support for Hong Kong and Macao.

It has shortened the distance between Hong Kong and Macao and the mainland, further highlighted the advantages of Hong Kong and Macao backed by the motherland, and can share the dividends of national development faster and better, and catch the express train of national development. <>

The Hong Kong-Zhuhai-Macao Bridge is politically significant.

This bridge is a fruitful achievement of the "one country, two systems" in practice, and truly embodies the specific practice of "one country, two systems" in the construction and operation management of the bridge.

After the bridge is opened to traffic, it will be divided into the strategic goal of "one-hour living circle" in three places, and the era of urbanization and integration of the Pearl River Delta is coming. Improve the economic imbalance between the two sides of the Pearl River Estuary.

Increasing Hong Kong's economic driving role in the west coast and even western Guangdong, the bridge provides the most convenient and socially largest transportation infrastructure for the construction of the Greater Bay Area, and forms a convenient east-west corridor for the entire Guangdong and surrounding areas.

Hong Kong-Zhuhai-Macao Bridge design features:

In view of the harsh requirements of the cross-sea project, such as "low water resistance", "non-interference with water, land and air three-dimensional communication lines", "environmental protection" and "driving safety", the Hong Kong-Zhuhai-Macao Bridge adopts the architectural form of "bridge, island and tunnel".

The whole section of the bridge presents an S-shaped curve, and the axis direction of the bridge pier and the flow direction of the water source Kailiu are roughly equal, which can not only alleviate the driver's driving fatigue, but also reduce the water resistance rate of the bridge pier, and improve the aesthetics of the building. <>

Summary. The Hong Kong-Zhuhai-Macao Bridge is the first large-scale transport infrastructure jointly built by Guangdong, Hong Kong and Macao under the condition of "one country, two systems". The route of the project starts from the Hong Kong Port Artificial Island near the Hong Kong International Airport, connects to Zhuhai and Macao Port Artificial Island and Zhuhai Link to the west, and ends at Zhuhai Hongwan, with a total length of 55 kilometers.

The construction of the Hong Kong-Zhuhai-Macao Bridge will be a historic project, and the Hong Kong-Zhuhai-Macao Bridge Authority is a public institution organized by the Hong Kong Special Administrative Region**, the people of Guangdong Province ** and the Macao Special Administrative Region**. The main task is to undertake the organization and implementation of the construction, operation, maintenance and management of the main part of the Hong Kong-Zhuhai-Macao Bridge.

The Hong Kong-Zhuhai-Macao Bridge was built there.

The Hong Kong-Zhuhai-Macao Bridge does not belong to any city, it is a traveling bridge connecting Hong Kong, Guangdong, Zhuhai and Macau. The Hong Kong-Zhuhai-Macao Shenqi Bridge is located in the Lingding Ocean area of the Pearl River Estuary in Guangdong Province, China, and is the southern ring section of the Pearl River Delta Ring Expressway.

Summary. Hello dear, glad to answer for you.
