It is a comprehensive term for evaluating foundation stability. The soil strength test theory is the theoretical basis for studying and determining the foundation bearing capacity.

[0003] After searching Chinese patents (publication number: CN219364741U), a foundation bearing capacity static load detector is disclosed, which solves the problem that the commonly used detector is only limited by inserting a semicircular fixed seat into the pipe pile, without leveling the load-bearing plate, and cannot ensure the stability of the gravity of the load-bearing test block placed on the load-bearing plate, thereby affecting the test effect.

Therefore, a foundation bearing capacity static load test auxiliary mechanism is needed to solve the above problems. Utility Model Content
