The utility model increases the load above the weight measuring block by the static load method, and the gravity of the pile foundation is displayed through the weight display table by the gravity sensor installed inside the weight measuring block, and the pile foundation dynamic measuring instrument is started to check the reflected wave of the pile foundation. The integrity of the pile foundation is checked to prevent the existence of cracks and other scars on the pile foundation, which will affect the subsequent support and bearing capacity. The ultrasonic detector is started to perform sound wave transmission detection on the pile foundation, and the defects of the pile foundation are detected to prevent the existence of strength defects in the pile foundation, which will affect the subsequent support and bearing capacity. The detection results of the pile foundation dynamic measuring instrument and the ultrasonic detector are displayed on the display.
