Application of Nondestructive Testing Technology in Concrete Quality Detection of Wind Turbine Foundation
Due to the imperfect concrete pouring of the wind turbine foundation or the wind-induced fatigue,it may lead to quality defects in the concrete and the deviation of the foundation ring level,which will affect the safe operation of the wind turbine.Taking the quality inspection of wind turbine foundation concrete in a wind farm in Guizhou as an example,the nondestructive testing of wind turbine foundation concrete was carried out by using comprehensive geophysical exploration methods such as ultrasonic rebound synthesis method,three-dimensional real scene modeling method and three-dimensional ultrasonic imaging method.The total station was used to measure the deformation of the foundation ring and the deviation value of the horizontal degree,and the test results were analyzed.The results show that there is no defect in the deep part of the wind turbine foundation concrete,but there are cracks and broken defects in the shallow layer of the concrete inside the foundation ring;The measured value of the foundation ring level exceeds the design requirements.The test results can provide a basis for the evaluation of concrete defects of wind turbine foundation and provide data support for the correction of foundation ring.
