AI Technical Summary
When traditional anti-uplift piles are constructed in water-rich strata, the protruding planes affect transportation and handling, and the single frictional resistance has poor bearing capacity, which cannot effectively enhance the anti-buoyancy capacity of the building.
A construction device for large-scale basement anti-tension piles in water-rich strata is adopted, including a mobile frame, a fixed support, a lifting frame, a mobile platform, a threaded rod, a motor, a transportation component, and an installation system. Driven by the threaded rod and the motor, the device utilizes high-efficiency modules and area-enlarging components to enhance the contact area and bearing capacity between the anti-tension piles and the foundation.
It enables automatic adjustment of the contact area between the tension pile and the foundation and enhances the bearing capacity, thereby improving the construction efficiency and bearing capacity of the tension pile and avoiding obstacles during transportation.
