Single Pile Foundation Pile Engineering Project for Zone C of Zhongguang Nuclear Pingtan Dalian Offshore Wind Farm


The Single Pile Foundation Pile Engineering Project for Zone C of the Pingtan Dalian Offshore Wind Farm of China Guangdong Nuclear Power Corporation is located in the northeast of Dalian and Xiaolian in Pingtan County, Fujian Province, and in the northern sea area of the island on the northeast side of Baiqing. The area has abundant wind resources, but the address conditions are complex, the marine hydrological conditions are poor, and the construction window period is short. In order to seize the construction window period, "Huaxi 5000" immediately held a technical briefing meeting with the wind power project department of China Communications Third Navigation Corporation after entering the site to discuss the technical plan, Conduct safety analysis and overcome difficulties such as poor weather, fast water flow, and large underground surges. On May 19, 2019, a C15 single pile with a length of 70.4 meters, a diameter of 6.3 meters, and a weight of 774.56 tons was successfully lifted using a single hook and three lifting points for the first time. This single hook lifting process is different from the domestic offshore wind power single pile overturning construction, marking the safe and mature application of this technology.
