Study on Development and Applicaton of Hole Quality Detection Technology for Bored Grouting Pile

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.
