The V110-2MW wind turbine used in the Dashuikeng wind power project is Vestas' first type in the domestic market Models with anchor cage foundations. Compared with the traditional foundation ring foundation, the anchor cage foundation adds two key processes of anchor cage assembly and secondary grouting, in which the anchor cage is assembled and connected by four anchor plates and 144 high-strength bolts. There are strict technical requirements on the joints and joints, and the overall construction difficulty is greatly increased, which puts forward higher requirements on the technical ability of the construction unit and the management ability of the construction and supervision units.
In order to fully grasp the construction technology and ensure the high success rate of anchor cage assembly, the first wind turbine anchor of the Dashuikeng Wind Power Project Before the cage was assembled, the Construction Project Department organized several technical seminars. Managers of the project department, Vestas technicians, construction parties and supervisors participated in the meeting, carefully studied the operation instruction manual, discussed techniques and procedures, analyzed and mastered key points and difficulties, determined special plans for construction and supervision, and prepared for emergency response.
In the specific construction process, due to sufficient preparations in the early stage, the management is in place. The construction unit quickly grasped the key points of the anchor cage assembly. The first anchor cage was successfully assembled on May 29, 2017 and passed the tripartite acceptance of the project department, Vestas and the supervisor at one time. The key indicators such as flange levelness are better than the manufacturer's requirements. , reflecting the good work quality of excellence.
