Publish Date: 10 August 2014

摘要: 充分利用JJC-1D型钻孔灌注桩成孔质量检测系统,对所测孔径范围进行了扩展,运用分方位四次测量法提高了孔斜度检测精度,并通过实测泥浆电阻率、沉渣(大浓度泥浆)的电阻率,进行试验室研究、对比、分析,形成了检测沉渣厚度的经验参数,取得了较好的应用效果。

Abstract: By the full use of JJC-1D quality detection system for hole quality of bored grouting pile, the range of measured hole diameter is extened.The hole inclination detection accuracy is improved by 4-azimuth detection method, the actual measurement of mud resistivity and sediment ( high concentration mud) resistivity are comparatively analyzed in laboratory to obtain the experience parameters for detection on sediment thickness, by which good results are achieved.
