This utility model provides a foundation pile concrete strength testing device, including: a testing box, a pressure receiving plate, a dust storage chamber, and a dust return port. The testing box has a set of testing chambers for testing the foundation pile concrete blocks. At the upper center of each testing chamber is a set of pressure receiving plates for detecting the pressure at the lower end of the concrete blocks. The upper end of the pressure receiving plates is equipped with several sets of pressure sensors for detecting the pressure applied to the concrete blocks. Compared with existing technologies, this utility model has the following advantages: the support frame adjusts the tilt angle of the mounting platform through a rotating rod linked to a motor, adapting to different testing needs; the moving wheels facilitate flexible movement and positioning of the device; the electric cylinder and support frame are rigidly connected through flanges and bolts, ensuring stable pressure application; and the entire process, through the synergistic action of the pressure receiving plate and the lower pressure head, combined with automatic dust removal and angle adjustment functions, achieves accurate measurement and efficient cleaning of concrete strength.
