Device and method for testing sleeve connecting structure grouting compactness in hammering pre-pressing mode

The invention discloses a device and method for testing sleeve connecting structure grouting compactness in the hammering pre-pressing mode, and belongs to the field of testing methods and equipment.The bottom periphery of an outer steel structure pre-stressing member is fixed on a wall body of a steel sleeve connecting structure to be detected; a cover body of the outer steel structure pre-stressing member is provided with a through hole, and a nut is fixed at the position of the through hole. A force transmitting rod is a rigid rod body, and the middle portion of the rod body is externallytapped. The force transmitting rod penetrates the through hole in the cover body to be screwed into the nut, and threads on the rod body and the nut are in thread fit for driving the force transmitting rod to move up and down. The bottom of the force transmitting rod is closely supported on a grouting body of the steel sleeve connecting structure to be detected. A dynamic signal collecting sensoris attached to the force tr
