The foundation refers to the soil or rock supporting the foundation under the building. The soil layer serving as the foundation of the building is divided into rock, clay and artificial fill. There are two types of foundations: natural foundation and artificial foundation. The natural foundation is a natural soil layer that does not require human reinforcement, while the artificial foundation requires human reinforcement. Common ones include stone chip cushion layer, sand cushion layer, mixed gray soil backfill and compaction, etc. In the existing foundation bearing detection institutions of some civil engineering projects, personnel are required to manually lift the heavy hammer continuously, release the heavy hammer, let it fall naturally, hit the probe rod, and perform load-bearing detection on the foundation. This process requires extremely high labor force from personnel, the detection is not accurate, and the detection operation is relatively cumbersome.

[0003] When existing equipment performs load-bearing tests on foundations, a heavy hammer is usually released to impact a probe rod inserted into the ground to perform foundation load-bearing tests, which makes it difficult to remove the detection structure and to conveniently observe and record the foundation bearing pressure. In addition, the existing equipment is large in size and not convenient to move, and it is not convenient to move the equipment to perform multi-point tests on the foundation surface, which affects the accuracy and practicality of the equipment's load-bearing tests on the foundation.
