Which hotel building was moved to Nanjing Metro 1 Line as a whole? What the hell is going on?

The "Jiangnan Hotel" of the Public Transport Corporation was hydraulically translated by 26 meters!

Nanjing Jiangnan Hotel translated 26 meters in 7 days-May 28, 2006 5438+0

Morning News The highly anticipated translation project of Nanjing Jiangnan Hotel was successfully completed at 8: 35 pm on 26th after 7 days' efforts. The translated building is 6 stories high and 7 stories in some areas, with a total weight of about 8,000 tons. It is the largest project in China at present, and the anti-seismic technology is also used for the first time.

Wei Longwu, general manager of Dongda Special Foundation Engineering Co., Ltd., who is in charge of the project, told the reporter: "Generally speaking, translation means replacing the house with a bracket. There are rollers at the lower part of the bracket, and there are tracks at the lower part of the roller, and then the house is separated from the foundation, and the house becomes a movable object. Then jack up the house with jack and other equipment, and fix it on the new foundation after reaching the predetermined position. "

The building covers an area of more than 5,400 square meters and weighs more than 8,000 tons. Coupled with the use of isolation technology, the project is more difficult. Since noon yesterday, isolation pads have been installed in the load-bearing part of the building, and the overall moving speed has been reduced from every 20 minutes 15cm to 3-5cm every 20 minutes. Because of the low friction coefficient, the two layers of steel plates of the isolation pad were once squeezed away by the building. After re-processing, Jiangnan Hotel finally moved to its new address at 8: 35 pm. Walk 26 meters in 7 days.

It is reported that the original price of the building is about 6.5438+0.86 million yuan, and the translation cost is about 4 million yuan. The owner of the building, a person in charge of Nanjing Public Transport Corporation, said, "Jiangnan Hotel was retained at a cost of less than 1/4, and the project time was saved for two years, which was very cost-effective."
