Leveling and deviation rectifying method and device for offshore wind power barrel type foundation and application of leveling and deviation rectifying method
The invention discloses an offshore wind power barrel type foundation leveling and deviation rectifying method and application thereof, and the method comprises a low-pressure grouting drainage process and a high-pressure grouting deviation rectifying process which are realized by an offshore wind power barrel type foundation leveling and deviation rectifying device; the low-pressure grouting drainage procedure comprises the steps of determining the grouting amount and grouting; and the high-pressure grouting deviation rectifying procedure comprises high-pressure grouting, negative pressure pumping and leveling. The method is suitable for accurate leveling after sinking installation of the offshore wind power barrel type foundation and deviation correction after accidental inclination of the barrel type foundation in the normal operation state, the levelness of the foundation is kept far below the standard requirement all the time in the operation process, the working stability and the power generation efficiency of a fan are improved, and the method has the advantages of being simple, low in cost, high in practicability and the like. And the application range is wide.
本发明公开了一种海上风电筒型基础调平纠偏方法及其应用，该方法包括低压灌浆排水和高压灌浆纠偏工序，由海上风电筒型基础调平纠偏装置实现；低压灌浆排水工序包括确定注浆量和注浆；高压灌浆纠偏工序包括高压注浆、抽负压和调平。本发明方法适用于海上风电筒型基础下沉安装后的精确调平，亦适用于筒型基础在正常运行状态发生意外倾斜后的纠偏，使得基础在运行时始终保持远低于规范要求的水平度，以提高风机工作稳定性和发电效率，具有方法简单，成本低，适用范围广的优点。
