Abstract

Static cone penetration testing machine is a device for in-situ testing of soil parameters in foundations. During use, the surface of the probe rod is covered with soil, which affects its performance. This article proposes a self-cleaning static cone penetration testing machine. When the hydraulic cylinder drives the probe rod to move upward, the positioning plate is moved to place it on top of the upper cover plate. Furthermore, the probe first passes through a circular pipe close to the soil layer. The circular pipe sprays water evenly onto the surface of the probe through a high-pressure nozzle, and then flushes the surface of the probe to remove some soil. Then the outer wall of the probe comes into contact with the cleaning sponge through the cleaning hole, and the cleaning sponge rubs against the surface of the probe to remove a part of the soil on the surface of the probe. Finally, the probe passes through another annular tube, which sprays water evenly onto the surface of the probe through a high-pressure nozzle, and then performs a secondary flushing to clean the soil on the surface of the probe. Reducing the situation where soil adheres to the probe rod for a long time and causes corrosion, achieving the effect of easy cleaning of the soil on the surface of the probe rod.
