| Abstract: | Introduction The icebreaking cone structure is a unique structure of the offshore wind power single pile foundation structure in north. The installation of the icebreaking cone is one of the key points and difficulties in the construction of the single pile foundation. The grouting connection technology solves this problem through assembled construction successfully. For the first time in China， a single pile icebreaking cone structure is used in an offshore wind power project in Dalian. Method Supported by the engineering practice of the project’s icebreaking cone grouting construction he critical technique of single pile icebreaking cone grounding construction was studied including installation preparation， grouting material selection， grouting pipeline design and optimization， grouting plugging and grouting construction quality control etc. Result In this study， by using Ugrount? SKG-V， self-developed high-strength grouting material， the small-scale containerized integrated marine wind power grouting equipment and the self-developed underwater grouting technology， the material and construction performance had met the requirements， and the grouting connection between single pile icebreaking cone structure and single pile was successfully completed for the first time. Conclusion This material and technology are expected to be widely applied in the single pile foundation structure of offshore wind power in northern China. |
