On June 7, a four-storey fire station was moving slowly at the site of the power plant Phase IV expansion project in Gedian Economic Development Zone, moving a total of 207 meters.
Originally built in 2019, this fire station, with a 12.15-meter-high main structure, is a three-story frame building with a length of 48.6 meters and a width of 20 meters, covering an area of more than 1,000 square meters, with a total floor area of 3,112.56 square meters and weighing 3,600 tons.
The provincial key project Ezhou Power Plant Phase IV (2×1000MW) Expansion Project is in full swing, but one obstacle encountered in the “five passes and one leveling” process: the fire station is within the scope of the planning project.
Liu Chunwei, Deputy Director of the Economic and Development Bureau of the Management Committee of the Gedian Economic Development Zone, said that if it was torn down and rebuilt, it would cost twice as much and would be time-consuming and laborious. “To ensure the completion of construction by the end of June, after many discussions, engineers finally came up with a new plan to 'pack up' the entire fire station and move it to an open space 207 meters away,” he said.
This building has a total of 44 load-bearing columns and the engineers installed for them 44 “steel boots”. Steel boots are connected with steel structure and telescopic rod to ensure that the structure of the whole building is not deformed. Wearing “steel boots”, the building is “stepped” on the slide, with the help of professional equipment to move and rotate at a constant speed.
Zhou Zhiyong, Chief Engineer of Ezhou Power Plant Phase IV Project Department of Wuhan Jucheng Structure Group Co. , Ltd. , introduced that during this move, the engineers adopted the rigid axis rotation technique and the push translation technique of the steel slide way for the first time. The overall implementation process consists of two rotations and two translations. “This improves the efficiency by three times and reduces the cost by more than 50% compared with normal moving.” he said.
