Repairing method of fan foundation
The invention relates to the technical field of wind turbine foundation treatment in wind power generation engineering, and discloses a wind turbine foundation repairing method which comprises the following steps: step 1, surface cleaning; secondly, first-order drilling is conducted; step 3, checking in the hole; step 4, cement-based material grouting; step 5, curing; sixthly, second-order drilling is conducted; seventhly, hole interior inspection is conducted; 8, grouting with an epoxy grouting material; step 9, curing; step 10, surface recovery; the problem that an incompact void layer exists in a fan foundation is solved, the cement-based high-strength grouting material is used for filling large holes and cracks in the foundation, after the first-order grouting material has certain strength, the epoxy grouting material is adopted for second-order grouting, small holes and cracks in the foundation are grouted, and the effect that the large holes and cracks in the foundation are not dense is achieved. And the effect of slight damage or even no damage can be achieved in repairing, repairing is firmer, and the construction cost is low.
本发明涉及风力发电工程中的风机基础处理技术领域，公开了一种风机基础的修复方法，包括：步骤一清表；步骤二一序钻孔；步骤三孔内检查；步骤四水泥基材料灌浆；步骤五养护；步骤六二序钻孔；步骤七孔内检查；步骤八环氧灌浆料灌浆；步骤九养护；步骤十表面恢复；本发明解决了风机基础中存在不密实脱空层的问题，利用水泥基高强灌浆材料填充基础内较大的孔洞和裂隙，待一序灌浆材料具备一定强度后，再采用环氧灌浆料进行二序灌浆，灌注基础内较小的孔洞和裂隙，可以使修复达到微损甚至无损的效果，使得修复更加牢固，且工程造价便宜。
