Taiyuan: \”Walking\” 24 meters south, the overall translation of the north gate of Yingze Park with more than 600 tons has been completed

On August 28, after 51 hours and 10 minutes, the north gate of Yingze Park, weighing more than 600 tons, was successfully moved southward for 24 hours. meters, creating favorable conditions for the normal construction of Taiyuan Metro Line 1. This is the first translation project of an antique building in Taiyuan City, and the first project in Shanxi Province to use roller translation technology to completely translate a building.

The north gate of Yingze Park is the \”main entrance\” of the park, April 2010 The architectural form of the completed North Gate Archway is modeled on the East-West Archway of the Yonghe Temple in Beijing. Its majestic design and ancient and elegant shape make it a popular \”attraction\” for people to check in and take photos. Its location happens to be in the open-cut section of Taiyuan Metro Line 1 under construction, so it needs to be relocated. After 6 large-scale expert consultations and program demonstration meetings, the \”translational\” construction plan was finally determined, which will \”uproot\” the north gate of Yingze Park, from the basic raft to the ground paving and ear rooms, without removing any brick or tile. The entire body is displaced under mechanical traction.

The north gate archway is about 13 meters high, 6.8 meters wide and 26 meters long, with a total weight of more than 600 tons. The structure has both a modern reinforced concrete frame and antique painted and wooden components. During the translation, instability, overturning and cracking are the biggest risk points [Interview: Zhu Dianjun, Chief Engineer of Taiyuan Metro Line 1 104 Bid Project of China Railway 11th Bureau] (During the entire translation stage, the entire gate archway is under stress. The original stress on the entire surface will be changed to the stress on six fulcrums. The differential settlement of these six fulcrums is the main factor causing cracking. To address this point, we used early auxiliary precipitation and optimized the cross-sectional size of the track beam to increase reinforcement. Increase this stiffness to ensure that the error of the track beam is controlled within five millimeters to ensure smooth translation)

After a large number of numerical simulations and calculations, combined with the structural characteristics and geological characteristics of the gatehouse, steel sheet pile maintenance, archway foundation excavation, translational track beam construction, foundation separation, and translation began on June 25 System installation and debugging and other preparations for the move took two months, and the move of the north gate of Yingze Park began at 11:18 on August 26.

The advancement speed is eight centimeters per minute. It’s eight centimeters and that’s the approximate speed)

From day to night, and then from night to day, 51 hours and 10 minutes, under the constant traction of machinery, in the whole process Under close monitoring, the huge gatehouse moved 24 meters smoothly and smoothly to the designated location.

[Interview: Deputy Director of the Engineering Management Department of Taiyuan Rail Group. Lian Haiping] (On the one hand, it is to ensure the smooth construction of our rail transit, and at the same time, it is to preserve the imprint of our city.Preserving the beautiful memories and feelings of our Taiyuan people)

In ancient times, there was a foolish old man who moved mountains and persevered. Today, there are skilled craftsmen who overcome difficulties. Through the formation of an expert team, multiple demonstrations, the use of multiple innovative technologies, careful consideration, repeated deliberation, and continuous improvement, the translation effect of the north gate of Yingze Park is good, and the gate building structure is stable. It pioneered the use of translation technology to solve the site occupation problem in rail transit construction in North China. the first of its kind.

[Our reporter: Wang Weidong] (The simple and elegant north gate of Yingze Park is not only a symbol on Yingze Street, but also deeply engraved in the hearts of every Taiyuan person. The future North Gate will continue to witness the development of this city in its old appearance. Feel the human fireworks of the beautiful Taiyuan City)
