This equipment is commonly used in the field of civil engineering, especially in building, road and bridge construction projects to ensure that the foundation can withstand the expected loads and environmental impacts.

[0003] After searching, the applicant found that a Chinese patent disclosed "a kind of foundation pull-out performance testing equipment", and its publication (announcement) number is "CN219386432U". This patent mainly drives the bidirectional screw to rotate by setting a motor, and the bidirectional screw drives the moving parts to move closer or farther from each other, and the moving parts drive the connecting rod to move, and the connecting rod drives the fixed plate to move, and the fixed plate clamps the pile body. This structure can adapt to piles of different sizes and specifications, and improves the applicability of the equipment. However, when performing pull-out testing on the foundation, the pile foundation in the foundation is usually tested for pull-out.
