Bridge hole grouting quality inspection instrument, specialized for the construction industry

The TS-QJ702 (A) Bridge Hole Grouting Quality Inspection Instrument uses the elastic wave (sound wave) transmission method to detect the overall density of prestressed hole grouting in bridges. The giant magnetic acoustic source excites elastic waves on the lock and beam at one end of the hole, and receives elastic wave signals on the lock and beam at the other end of the hole. The density of hole grouting is determined by analyzing the propagation characteristics of elastic waves in the hole and beam.
