The quality of the steel cage processing in pile foundations directly affects the quality evaluation of the foundation. The spacing of the longitudinal main bars of the steel cage is a key quality control point. To ensure that the longitudinal main bar spacing of the steel cage meets the design requirements, the longitudinal main bar spacing must be accurately controlled by drawing lines on the reinforcing rings during the cast-in-place pile reinforcement cage processing. This slow drawing speed affects the steel cage processing time. Utility Model Content
