The largest bridge of Hunan Province, undertaken by the China Railway Five Bureau, began to upgrade

On August 3, the rapid transformation of Wanjiali Road in Changsha City, built by the China Railway Fifth Bureau. It is understood that the top -up engineering department in Hunan Province is the largest bridge at the top of the top of the bridge.

The end point of the Wanjiali Road Viaduct is located about 383 meters north of the Jiaoyuan Road. In order to ensure the full connection with the new viaduct, it is necessary to push up the existing two -crossing bridge. The total length is 150 meters, the total weight reaches 9255 The tons, the maximum height of the top rise is 5.4 meters, and the top rise area is 3750 square meters.

The project department of the Fifth Company of the China Railway Five Bureau is equipped with a 7 -unproof pressure pumping station, which adopts a set of 14 -point synchronization control system to meet the needs of the overall synchronization of the construction and control. According to the top upgrade process, the bridge deck rises at about 3 mm per minute, and the construction cycle of the entire top upgrade project takes about 1 month. After the bridge deck is in place, the pier columns are connected and the bridge renovation construction will be used for 1 and a half months. The new and old elevated connection will be achieved at the end of November.

After the rapid transformation of Wanjiali Road, the North Extension Line Project will be completed, and the seamless connection of Xiangfu Road, Wanjiali Road Elevator, Xingsha Link and the Second Ring Road will effectively alleviate the existing Wanjiali. The traffic saturation problem in North Road effectively relieves traffic congestion in the north and south of Changsha, shorten the driving time of the stars and sandy areas to enter the main urban area, and accelerate the integration and development of Xingsha and Changsha urban area.
