The longest Bridge of Russia Crimea Bridge

The Crimea Bridge, also known as the Crimson Strait Bridge or the Chiqiao Bridge, is a parallel "Gemini" bridge. The Talman Peninsula in the Dar and Crimean carved Chicheng Peninsula.

The bridge is 19 kilometers long, among which the cross-sea part is 7.5 kilometers long, and the main cross-bridge is 33-35 meters. It is the longest bridge built in Russia in history and the longest bridge in Europe. The total of 227 billion rubles (about 25.5 billion yuan) in the bridge project, known as the "Century Project" of Russia.

In February 2016, the road bridge and the railway bridge started construction at the same time. Highway bridge opened to traffic on May 16, 2018. The railway bridge passenger train opened on December 23, 2019. Cargo train was opened on June 30, 2020.

After the opening of the bridge, the traffic volume of the car quickly exceeded the carving the Red Strait ferry, and the peak tourist season in the summer is the peak of the Crimea Bridge. On August 15, 2020, 36,393 vehicles were created on August 15, 2020.

The bridge uses more than 7,000 piles, and these piles are below 91 meters below the water. Some piles are tilted to make the structure more stable during the earthquake.

The geological conditions of the Red Strait are harsh, and there is a constructor, and the base rock is covered by a 60 -meter -high silt layer. About 70 mud volcanoes were found. Considering the structure of the strait and marine water flow, some experts expressed doubt about the safety of the project.

British invented new bridge injury warning sensor

Researchers of Queen Bellster University (QUB, Queen's University Belfast) researchers have developed a new type of sensor that can detect the changes in the riverbed and warn before the bridge is damaged, making the bridge operation safer and help extreme extremes to extreme extremes Prevent the bridge collapse in the climate.

The scouring and erosion caused by the changes in the river bed usually do not leave obvious signs of damage, so it is also one of the main reasons for the collapse of major bridge structures worldwide. The hidden dangers of bridge caused by scouring cause the UK to reduce an average of 8.2 million travelers each year, resulting in economic losses of 60 million pounds.

At present, the test of the initial model of the sensor has been completed. Recently, the sensor will be applied on a bridge in Northern Ireland with other structural health monitoring equipment to ensure the safety of aging bridges. The sensor research project is funded by Uk Research and Innovation's IMPACT Acceleration Accounts, and Invest Ni is responsible for market development funds.

Global bridge construction market development report 2022-2027 released

"Bridge Construction Market: Global Industry Trends, SIZE, Growth, Opportunity and Forecast 2022-2027). In 2021, the global bridge construction market was worth $ 870.4 million. It is estimated that by 2027, it will reach US $ 1.193.3 billion, and the compound annual growth rate from 2022-2027 will be 5.10%.

The increase in the total number of road traffic and the total number of vehicles, the expansion of the railway network, the various favorable measures adopted by governments and non -governmental agencies, the development of new equipment and systems, the acceleration of the process of urbanization, strong economic growth, and infrastructure development projects Increased investment and the increase in the use of prefabricated concrete boards have a positive impact on market prospects.

The report is estimated that the development trend of the next five years is sorted by the bridge type: beam bridge, truss bridge, arch bridge, suspension bridge, cable bridge and other bridges. Classified by materials: steel, concrete, and composite materials. The strength competition companies of the bridge industry include: Grupo ACS, AECOM, Balfour Beatty PLC, Bouygues S.A., China Transportation Construction Co., Ltd., China Construction Engineering Corporation, Fufang Corporation, SAMSUNG C & T Corporation, Strabag SE And Vinci SA.

Norway's longest bridge built with BIM technology is about to open to traffic

Near Norway, near the city of Hønefoss, about 31 miles in Oslo, the RANDSELVA Highway Bridge is under construction, with a total length of about 634 meters, and the highest point is about 33 meters from the ground. The bridge spans a variety of terrain and buildings such as rivers, valleys, foot hills, and existing railway lines. It will be the longest bridge built by Norway's history without using two -dimensional plane drawings. It is expected to open to traffic in July. The person in charge of the project stated that the use of BIM can accurately control and adjust every detail of the bridge construction compared with the traditional method, reduce the expensive cost of the drawing of drawings and additional materials during the construction, saving about 10%of the cost. Especially in multinational projects, BIM's standards make collaboration easier. 2D drawings are gradually replaced by major changes in the construction industry, and the application of BIM models will also promote the large -scale automation construction of future construction projects.

Georgia Diamond Bridge will get the Guinness World Record

Georgia, a new diamond -type glass suspension bridge from Tsalka Canyon, west of the capital, is open, with a total length of 280 meters from the bottom of the canyon, with a construction period of 3 years. The diamond bridge is designed by Kass Group, inspired by the natural form of the canyon.

The suspension diamond structure in the center of the glass suspension bridge is currently the largest and highest free suspension structure in the world. It is currently applying for the Guinness World Record.

Diamond structure is used for multi -functional leisure areas. Visitors can enjoy the beauty of the canyon while enjoying drinks. They can also experience high -altitude zigzag bicycle projects and cross the canyon.

In the future, ecological channels, visitor centers, hotels, swimming pools and other structures used to organize large -scale activities, it is expected to cost nearly 65 million New Zealand dollars (120 million Georori Alari).
