Paton Bridge

   Another no less unique structure of the capital is a bridge named after Yevgeny Paton. Its peculiarity lies in the fact that he was the world's first all-welded bridge. Prior to his arrival in the construction of bridges often used rivets. Paton Bridge consists of 264 spans of blocks that are connected to a construction joints with total length of 10,668 meters.
This method of bridge construction was born in Kiev, and soon became known throughout the world. At present, most of the bridges over the water area is being built the same way that a bridge was built Paton. This bridge has a length of 1543 meters. The width between the curbs is 21 meters and a width of sidewalks in the 3-meter.
Of particular interest is the fact that during the life of Eugene Oskarovitch Paton in the project document this bridge appeared as the Kiev city bridge. This bridge was one of the largest bridges in Europe, and was able to combine two seemingly incompatible notions: welding and bridge building. Paton include such services as the development of the fundamental principles of building solid bridges, training base for the development of the domestic theory of welding and the use of their theoretical studies into practice. Thus, the Paton Bridge was supposed to be another creation scientist in the Ukrainian capital, is the third in a row.
In the place where today is located Paton Bridge, the Revolution was a chain bridge. Its author was a British engineer O. Vignola. Restore destroyed during the Revolution Academy undertook to bridge Paton, in collaboration with the best engineers of the Institute of Electric Welding. It was decided to use the all-welded connection method spans. Working to rebuild the bridge began with studies that were conducted here to study the detailed form of new construction of the bridge proposed by Paton. As part of these studies tested weld the main components of the bridge, as well as transverse members. In addition, a predicted service life and endurance of the future bridge. For the first time in the history of bridge engineering have developed special equipment that is designed for automated welding of field joints sploshnostenchatyh farms. Such designs for the two years were made in Dnepropetrovsk, and then delivered to the Ukrainian capital.
Throughout the years pondered the idea of ​​erecting Paton welded bridge. That he felt strongly that the construction of this bridge is not used conventional riveted connections, and welding was used. But agreed with him not at once. The most important argument of his opponents was that the design of welded bridge would compromise a large number, as drivers and pedestrians alike. Scientists completely forbidden to use welding. But in their argument suddenly intervened, Nikita Khrushchev, who is head of the Ukrainian Communist Party. He listened carefully to the arguments of both sides and concluded that Paton should be given a chance to implement their ideas. Thus, the construction project has been approved. However, Patton decided to cheat a little, and originally proposed to produce spans rivet-welded. Unfortunately, such designs were fragile: they soon cracks about a meter long. Since construction was dismantled. Patton was not going to give up. He suggested that this failure of automatic welding process is not guilty, but the true reason for the failure lies in the fact that you need a special steel. After that, Paton asked the BA Kasatkin to help find a steel suitable for welded construction of the bridge. Conducting numerous experiments with different chemical compositions have failed. Out of this situation came spontaneously. Resting in a sanatorium near Moscow, Patton wrote to Kasatkin. In his letter, he asked him to trace the presence of dependence, which could be between sulfide lines and fissures encountered in the welding seams. His assumption of Paton went straight to the point.
The first flight of the Future of the bridge began to mount in the summer of 1941. Isidore Ilyich Frumin, who is a student Paton was responsible for the execution of flux. Construction went quickly, but the Great Patriotic War, which began in the same year, for a long time froze the project. Several piers that were built before the war, were blown up by invaders during their retreat from Kiev. restoration work began almost immediately after the war and lasted for ten years. Unfortunately, Paton - the main creator of this bridge has not lived up to its opening just three months. November 5, 1953 the grand opening of the bridge, which after the death of a well-known academician was named in his honor. Paton Bridge is a real "technical" a miracle that more than once enthusiastically described B. Olejnik. He called the bridge a rocket, flying from the past into the future. Paton Bridge in a short time has become a true city landmark and one of the most favorite places to walk among the locals. Until recently, the bridge went tram.
For many years, Paton Bridge Road Transport is the only crossing over the Dnieper. In this regard, he felt an enormous burden on a daily basis. Initially, according to project documents, power of the bridge was 10 thousand cars a day. In 1976 to check the strength of the bridge gave excellent results. It was found that the margin of the bridge is right up to 70 000 vehicles per day. Major reconstruction of the bridge was carried out in 2004. In the first place was dismantled tramway connecting the city center and the left-bank areas: Rusanivka, Resurrection and Darnitsa. This has increased the capacity for road transport. With regard to the roadway of the bridge, it was divided into seven lanes: three lanes in each direction with a reverse in the center. The ends of the band expanded to 3.5 meters, making it easier, thus, the passage of large vehicles, such as trolley buses, which began to go here instead of trams. Currently, there is a new project of reconstruction of the bridge Paton, who is under consideration. As part of his proposed to expand the roadway of the bridge to 37.3 meters. This can be achieved by replacing concrete slabs separate plates, made of steel. Also, the project is proposed laying of existing communications and corrosion protection of metal parts of the bridge. Because of the frequent accidents that occur on the bridge Paton, by management of GAI of Kiev bridge was dedicated, as it has long been done in the West Ukrainian cities. Lighting of the bridge occurred February 1, 2008. To unload the nearby streets in May 2009 under the bridge, Patton began to build a tunnel - a new transport interchange.
