Henan Daily client reporter Song Min

At 8:30 on September 20th, after 90 minutes of turning operation, the T structure with a weight of 21,000 tons rotated 67.5 ° clockwise, safely across the Ningxi Railway and G312 National Highway, and achieved "gorgeous turns" and precise docking in the air. The successful completion of the turntable has laid a solid foundation for the successful opening of the West Gorge to the Xichuan section (hereinafter referred to as the Xilian Expressway).

The West Pyreal Cross -Ningxi Railway Lijiao Bridge is built by Henan Province Xizhu Expressway Construction Co., Ltd., one of the project control projects undertaken by Luoyang Engineering Headquarters of China Railway Zhengzhou Bureau Group Co., Ltd. 140 meters, 25.7 meters wide, 23 meters high in the main pier.

The T beam is a single -box three -bedroom straight -stitches T structure. The 23 -meter -high pier pillar plus a single box three -bedroom T beam height, which is close to the 10th floor. The car is so heavy, and the rotation of such a behemoth can be imagined.

In order to ensure safety quality and successfully complete the turntable, the T structure beam uses the basket to hang the basket in the direction of the National Highway on the north side of the railway, and then pull the traction Slun clockwise to 67.5 ° with two 500 tons of continuous tensor. Position, implement the construction process of "precise docking" by 1 mm. This process has greatly reduced the impact on existing operating railways and national roads, which not only reduces construction safety risks, but also ensures driving safety.

After the project is completed, it will improve the regional high -speed skeleton road network, and at the same time can effectively strengthen Zhengzhou as the radiation driving role of the central city, greatly improve the traffic conditions in the southwestern Henan mountainous areas, promote the development of tourism and mining resources along the route, and promote poverty alleviation along the line. It is of great significance to drive the economic and social development of southwestern Henan.
