The Core Functions of Pile Head Wire

1. Mechanical Connection and Force Transmission

The ingenious use of threaded engagement allows for a robust and secure connection between the pile body, such as precast concrete or steel pipe piles, and the bearing platform or anchoring device. This ensures a harmonious distribution of forces across the pile-bearing platform system.

Data: Threaded connections boast an astonishing efficiency rate exceeding 90%, significantly surpassing the traditional welding or grouting connections which hover around 60% to 70%.

Example: Within a single pile foundation tailored for offshore wind power, the resilient connection between the pile head wire and the flange effortlessly withstands a formidable vertical load of 1000 tons and a horizontal shear force of 50 tons.

2. Anti-Pull and Anti-Shear Reinforcement

The sophisticated thread profile design, featuring variants like trapezoidal or serrated threads, dramatically enhances the frictional resistance between the pile and the surrounding soil or concrete. This makes it a perfect fit for scenarios involving anti-floating or anchor piles.

• Testing: Threaded pile heads exhibit an astounding pull-out bearing capacity, ranging from 3 to 5 times higher than their smooth counterparts (e.g., increasing pull-out capacity from 200 tons to a remarkable 600-1000 tons for an 800mm diameter pile).

3. Optimization of Construction Efficiency

By eliminating the need for on-site welding and grouting processes, installation becomes a breeze with a simple twist, contributing to a staggering reduction in construction time by over 50%.

Case: A 30-story residential project ingeniously utilized prefabricated pipe piles and threaded pile heads, slashing the foundation construction period from a lengthy 45 days to a mere 20 days.

4. Quality Controllability

With factory-prefabricated threads, precision in tooth profile is guaranteed (with pitch error as tight as ≤± 0.1mm), effectively mitigating the risk of connection failures due to on-site construction errors.

Comparison: While the manually engraved threads on site achieve a qualification rate of only 70%, prefabricated threads soar above, reaching an impressive qualification rate exceeding 99%.
