Corrugated pipe grouting compactness detection device

A corrugated pipe grouting compactness detection device comprises an upper computer control end, a signal collector, two signal receiving sensors and two wireless excitation units, and the two signal receiving sensors are arranged on anchorage devices at the two ends of a prestressed duct to be detected respectively. The two wireless excitation units are respectively adsorbed at two ends of steel strands at two ends of a to-be-detected prestressed duct, the signal collector is respectively in signal connection with the two signal receiving sensors through a double-core microphone wire, and the upper computer control end is respectively in wireless transmission signal connection with the signal collector and the two wireless excitation units. According to the utility model, the WIFI module is additionally arranged, and a wireless transmission technology is applied to the whole detection process from the excitation instruction signal sent by the excitation unit to the signal acquisition completion and the signa
