In Shanghai area, borehole injection piles are used in large quantities for construction foundation in soft soil strata. The reinforcement cage for each injection pile consists of several parts linked together through welding. After the completion of the borehole injection pile construction, the inspection of the length of the reinforcement cage and the examination of welding quality constitute a very difficult problem. This paper recounts the technology and effects of applying high precision foundation pile diagnostic device and geological radar to the inspection of the length of reinforcement cage for the borehole injection pile.
