"There are still many advantages of Hamburg, Germany, and it is very meaningful for us to come here to see, let me continue to introduce it to you!" Robin took everyone, while visiting, while introducing, he was erudite and talented, and explained in depth and detail, Qu Lihua asked Robin for advice if there was anything he didn't understand.

Robin will also tell Qu Lihua that Qu Lihua has a very good impression of Robin, plus Robin is very down-to-earth, funny and humorous, there is no frame at all, and it does not make people feel restrained, everyone follows him, very relaxed and happy.

"Hamburg is the cultural center of North Germany, the University of Hamburg is the largest university in Germany, there are music, art academies, engineering and navigation schools, Hamburg has a well-developed transportation system, boats can reach the city center from all directions along the river, and many people take boats to work or shop. ”

"This city is a water city, it is the largest port city in Germany, I have introduced it to you earlier, we all know that Venice is a famous water city, Hamburg is bigger than Venice, there are more bridges, this is the characteristic of Hamburg, Germany, you can ride and wear to work, this is a unique place in this city. ”

Qu Lihua smiled, "Yes, many of our cities in China are land transportation, and young people usually take the subway or bus, take a taxi, or drive themselves to work, but there are still relatively few people who take the boat to work." ”

Robin smiled, "This is the characteristic of Hamburg, Germany, with dense overland transportation, underground railways in all directions, tunnels at the bottom of the main river, and a long tunnel through the bottom of the Elbe, which forms two links between the two sides of the river with the Colbrandt road bridge on the river. ”

"Hamburg in Germany is the bridge city of the world, with more bridges than Venice, Amsterdam and London combined. ”

"The Elbe River runs through Germany and forms a wide bay before it flows into the North Sea, where the port city of Hamburg was built, and water is an inseparable theme for this thousand-year-old city. ”

Not only does the main and two branch roads of the Elbe run through the city of Hamburg, but also the Ulster and Mühler rivers and a dense network of hundreds of rivers and canals spread throughout the city, and in the center of the city there are two artificial lakes, the Inner and Outer Alster, which were built in the Middle Ages to make use of waterwheels. ”

"There are a variety of stone, wood, iron, trestle and double-decker bridges in Hamburg, Germany, each with its own characteristics, and every time we visit one of Hamburg's bridges, it is like flipping through a book that records the history of the city, and the most famous bridges on the Elbe are the Tost Bridge and the majestic Colbrand Bridge in the harbor. ”

"I'll take you to take a look!" Robin took everyone to the front of the bridge, Qu Lihua and Meng Wenjie stood on the shore, looked at it, and were amazed.

"Wow, this bridge still looks spectacular!"

Robin nodded and smiled, "Yes, the Colbrand Bridge is a modern cable-stayed bridge, it is the junction of the eastern part of the Port of Hamburg and the Elbe Tunnel, the bridge is 3,940 meters long, 325 meters wide at its widest point, and cable-stayed steel bars up to 135 meters high. ”

"If you take a boat trip from the port of Hamburg, you can see its majestic form from a long distance, known as the 'head of a thousand bridges', comparable to the Golden Gate Bridge in San Francisco and the Brooklyn Bridge in New York. ”

"The bridge also has some history, and over time, the shortcomings of the cable corrosion during construction have led to the corrosion of an unknown number of cables, so that all 88 weather-corroded cables have been replaced with partially galvanized or fully galvanized cables. ”

"This requires the replacement of the Xu cable, the new cable not only has high-quality internal and external corrosion protection, but also after the professionals have studied the cause of the damage in detail, a number of improvements have been made to the cable consolidation area, adding a damper to suppress wind vibration, eliminating the bending stress in the transition area between the flexible cable and the rigid anchor head Cable saddle, and improving the design of the anchor to improve drainage. ”

"It turns out that there is still so much knowledge and exquisiteness!" Although Qu Lihua is not a bridge design and architecture major, after Robin's explanation, she feels that it is not easy to build a bridge that can stand the test of time, be strong, and have a load capacity.

It takes a lot of money, manpower and material resources to become a famous bridge, which is not only strong and beautiful, but also contains history and culture.

"The bridge is still very long, and the load capacity is still great!" Meng Wenjie also praised.

Robin said: "Yes, this bridge is very distinctive, I will take you to see other bridges, there are a lot of bridges in Hamburg, Germany, may not be able to see them in one day, we will go to several places in the next few days, representative bridges, I will introduce them." ”

"Okay!" Qu Lihua became more and more interested in listening, wanting to appreciate the "Thousand Bridges Style" of Hamburg, Germany, where the Leenpasteur Bridge and Kennedy Bridge in the city center have become the dividing line between the Inner and Outer Alsters.

Robin took everyone to these bridges to have a look, and stood on the Lenpasteur Bridge to see the beautiful view of the Outer Alster.

Robin looked into the distance and introduced: "The Lenpasteur Bridge was built in 1865, 48 meters wide, with light tracks, plus four lanes, and two tall flagpoles at the bottom of the flagpoles, decorated with luxurious carvings, facing the inner and outer Alsters, two five-pronged lampposts, which is the most luxurious bridge in Hamburg." ”

"This bridge is really beautiful, I saw the generosity and atmosphere of Europe, the design of the bridge, the lines are smooth, it looks like it is some age, but it is still very strong, the carrying capacity is still very good, and the decoration is also decorated in a common European way, which looks luxurious and atmospheric. Qu Lihua said.

Robin nodded, "Yes, but what we see now is a restored bridge, there was already a bridge before the location of the Tost Bridge now, it was a bridge connecting the old and new cities of Hamburg at that time, the old bridge was wooden, it was seriously damaged in the fire, and later considered that the wooden bridge could not be fireproof, or it was rebuilt with cement and marble relatively strong building materials." ”

"After the reconstruction, we saw the current style of the bridge, thanks to the bridge builders and the professional bridge builders who later repaired these bridges, without whose hard work the bridge would have ceased to exist. ”

"It reminds me of the history of Hamburg, where one of the worst fires in history occurred in 1842, which destroyed almost a third of Hamburg and destroyed the canal connection. ”

"After the fire, Hamburg ushered in a phoenix-like rebirth, began large-scale construction, Hamburgers took the opportunity to introduce advanced construction technology, widening roads, water supply systems, renovating canals, rebuilding ports, opening railways, of course, these are inseparable from the connection of bridges, in the following hundreds of years, Hamburg has never had a bridge accident, Hamburg's bridges stand silently, bear the heavy traffic, support the development of the city. ”
