Wind turbine foundation treatment method under deep pit condition
The invention provides a wind turbine foundation treatment method under a deep pit condition, and relates to the technical field of wind turbine foundation treatment. The draught fan foundation treatment method under the deep pit condition comprises the following steps that excavation leveling is conducted in a first set range of the bottom of a deep pit, and it is ensured that the bottom of the deep pit is located at a first design elevation; after the foundation pit is excavated and leveled, layered backfilling, layered compaction and layered detection are conducted on the foundation pit; continuously backfilling to a second design elevation, wherein the distance between the slope top edge line of the backfilled side slope at the elevation and the outer contour of the fan foundation is a first distance; after backfilling to a second design elevation, starting to construct a pile foundation and a fan foundation concrete bearing platform; and after the pile foundation and the fan foundation concrete bearing platform are constructed and detected to be qualified, the foundation pit continues to be backfilled to a third design elevation, and the distance between the slope top sideline of the backfilled side slope at the elevation and the outer contour of the fan foundation is a second distance. And the technical effect of effectively treating the deep pit so as to ensure the safety of the fan foundation is achieved.
本发明提供了一种深坑条件下风机基础地基处理方法，涉及风机基础处理的技术领域。深坑条件下风机基础地基处理方法包括以下步骤：对深坑底的第一设定范围进行开挖平整，确保深坑底部处于第一设计标高；基坑开完平整完成后，对基坑进行分层回填、分层压实和分层检测；持续回填至第二设计标高，在该标高处回填边坡的坡顶边线距离风机基础外轮廓为第一距离；回填至第二设计标高后，开始施工桩基与风机基础混凝土承台；待桩基与风机基础混凝土承台施工完毕并检测合格后，继续将基坑回填至第三设计标高，该标高处回填边坡的坡顶边线距离风机基础外轮廓为第二距离。达到了有效处理深坑从而保证风机基础的安全的技术效果。
