Another step closer to the opening of Yinxi high speed railway! Construction of Weihe super large bridge on the ground

On November 16, the construction of Yinxi high speed railway, an important part of the main channel of "eight vertical and eight horizontal" high speed railway in China, made an important breakthrough. In the morning of that day, with the completion of the last pile foundation grouting, the key control project of Yinxi high speed railway, Weihe super bridge, began to be constructed on the ground, laying a solid foundation for the completion and opening of Yinxi high speed railway in 2020. (November 18, China Railway Network) on November 16, the construction of Weihe River Bridge, an important control project of the Yinxi high speed railway, started in an all-round way, marking a new breakthrough in the construction of the bridge with the greatest difficulty in the construction of the whole Yinxi high speed railway. Weihe super bridge of Yinxi high speed railway is 13.6km long, which is a key and difficult control project of Yinxi high speed railway A 6031 a 6031 Yinxi high speed railway Weihe River super large bridge crosses many existing roads and rivers, which has the characteristics of difficult construction, heavy task and tight construction period. In order to meet the interconnection between Yinxi high speed railway and Guanzhong intercity railway, the bridge adopts the form of four line bridge. At the same time, the bridge is designed to cross the Weihe River by simply supported steel diagonal beam, which can ensure the need of drainage and flood discharge and minimize the damage to the ecological environment of the Weihe River

these special geographical conditions and urgent time give the construction personnel a "difficult problem". However, the construction personnel overcome such adverse factors as narrow site, high construction precision requirements, and high safety risks. Reasonably organize the construction and invest a large number of equipment and personnel to ensure the safety of the site. With the joint efforts of all the participants, the construction of Weihe super large bridge was officially started

on the morning of October 15 this year, Premier Li Keqiang also made a special trip in the rain to inspect the four sections of Weihe super large bridge in the first bid section of Yinxi high speed railway in Shaanxi Province, which was constructed by China Railway fifth Bureau and supervised by China Railway Research Institute. The four section of Weihe super major bridge is 4.16km long, with large project volume, complex bridge structure and tight construction period. It is a key and difficult project concerned by the state. Before the project exhibition board, the premier listened to and understood the report on the planning and construction of the railway network in Western China, and nodded frequently and affirmed the achievements

Yinxi high speed railway is a part of Fuzhou Yinchuan high speed railway of high-grade railway in the national medium and long term railway network planning. The Yinxi high-speed railway connects Shaanxi, Gansu and Ningxia, and the Yinchuan Xi'an high-speed railway is planned to be completed and opened to traffic by the end of 2020. At that time, the operation time of the train from Xi'an to Yinchuan will be shortened from the current 15 hours to within 3 hours After the completion and opening of the

Yinxi high speed railway, it will form a fast channel between the Guanzhong Economic Zone with Xi'an as the center and the Yellow City belt with Yinchuan as the center, which is of great significance for promoting the construction of the "belt and road", revitalizing the old revolutionary area of Shaanxi Gansu Ningxia, accelerating the coordinated economic and social development of the western region, and promoting exchanges with the developed regions in the Middle East
