China will build the world s tallest bridge in the sea, what other achievements of our country make

The Zhurong probe successfully landed on Mars.

China will build the world's highest bridge in the sea, every building is very worthy of great attention, and for every Chinese, has always been very proud and proud, our country has many achievements to be proud of, in fact, the most recent is the successful landing of the Zhurong probe on Mars, and indeed, such an achievement is very shocking, at that time successfully broke through the devil nine minutes later, the moment of arrival on Mars, the chief engineer of Tianwen-1 shed tears of excitement. <>

China is the second country to successfully settle in the rocket, before only the United States went to Mars, and this time after China settled in Mars, there is its own space, the food hall in the whole process, all the plans and arrangements, can be called textbook smooth and smooth, breaking through the devil's nine minutes, in the whole ** can clearly feel that China has been working hard to develop behind the science and technology. <>

In normal activities, each of us actually doesn't feel China's science and technology at all, but when every Shenzhou and every spacecraft in our country flies into space, we feel incredible.

When the probe successfully landed on Mars, the process has gone through layers of tests, and even if there is a second difference in the process, the entire probe may fail and fail to achieve the ideal effect we expected. Mars is fundamentally different from Earth in terms of environment, gravity and other aspects. Therefore, in the process of continuous research, it can be found that the Mars rover is still very powerful and strong.

In addition, China has also developed a new crown vaccine with only one shot, from the performance and the effect on all aspects of the human body, this shot of vaccine has no difference for other vaccines, and China, as the first country of the epidemic, with the fastest speed to let all our Chinese people, within a safe range, for us Chinese people, for every Chinese citizen, are very proud and proud, no matter when, always because they are a Chinese feel extremely happy.

Tempered glass is also quite proud, because in this regard, it is said to be made in China, and the quality is also very good, which is very slap in the face of foreigners.

It must be the Three Gorges Dam, how many years have passed, and it is still standing without any problems.

My country has the fastest high-speed rail in the world, and I am very proud to sit on it.

Qingdao Bay Bridge, also known as Jiaozhou Bay Bridge, is the starting point of the national highway network G22 Qingdao URL to Lanzhou Expressway, which is Shandong Province.

The part of the framework of the "five vertical, four horizontal and one ring" highway network is the "one bridge" in the "one road, one bridge and one tunnel" of the cross-sea passage on the east and west banks of Jiaozhou Bay planned by Qingdao City. From Haier Road, the main urban area of Qingdao to Huangdao through Hongdao to Huangdao, the bridge is 36 48 kilometers long, with an investment of 10 billion yuan, which lasted 4 years, and the total length exceeds the Hangzhou Bay Bridge in China and the Chesapeake Bridge in the United States, and is the longest sea-crossing bridge in the world today. The bridge was opened to traffic on June 30, 2011.

It is a large sea-crossing bridge designed, constructed and built by China. In 2011, it was listed in the Guinness Book of World Records and Forbes magazine in the United States, and won the honorary title of "The World's Best Bridge".

Guangji Bridge is the first large stone bridge across the sea in ancient China.

Ming Xuande ten years (1435) rebuilt, and added five piers, called Guangji Bridge; During the Zhengde period, another pier was added, a total of 24 piers. The piers are made of granite blocks, which is a valuable heritage in Chinese bridge construction.

The middle section is connected with 18 shuttle boats to form a pontoon bridge, which can be opened and closed, and when the big ship and wooden row pass, the pontoon boat in the pontoon can be untied and let the boat and wooden row pass. Then return the pontoon boat to its original place. This is China, and it is also the world's first large stone bridge with a switch movable type.

The bridge was overhauled five times in the Ming Dynasty, and 24 "watchtowers" of different forms (destroyed) were built on the piers. In the first year of Yongzheng in the Qing Dynasty (1723), two iron oxen were placed on the stone piers at both ends of the pontoon bridge, and the back of the ox was engraved with the words "Zhenqiao Yushui", but it has long been gone.

In 1958, due to traffic needs, the shuttle ship was dismantled and replaced with a direct bridge. In 1980, an iron ox was recast and placed on the bridge. As the folk proverb goes: "If you don't get to the tide in Guangzhou, you will go in vain; If you can't reach the bridge when the tide arrives, you will walk in vain."

The combination of beams and boats, rigidity and softness, movement and stillness, ups and downs, is a major feature of Guangji Bridge. Its east and west sections are the beam bridges of Chongling Liange and Lianfang Jimei, and the middle is the pontoon bridge of "the gang is connected and the dragon lies in the rainbow". It's a wonderful sight.

Qianlong of the Qing Dynasty had a poem praising it: "The Xiangjiang River is full of spring and dawn, and the eighteen shuttle boats lock and paint the bridge." "Xiangqiao Spring Rise" is therefore the first of the "Eight Views of Chaozhou". Structurally speaking, the combination of beams and boats has opened a precedent for opening and closing bridges in the world.

Guangji Bridge

Guangji Bridge is in the east of Chaozhou City, Guangji Bridge is one of the famous bridges in ancient China, was built in the Southern Song Dynasty in the sixth year (1170), lasted 57 years to build, the total length is 515 meters, divided into two sections of 18 piers in the east and west, the middle section is about 100 meters wide and called Jeju Bridge at that time.
