Product Description

The pile head wire is an indispensable element in the realm of pile foundation engineering, acting as the pivotal link between the pile body and the upper structure, including the bearing platform and connectors, or significantly boosting the bearing performance at the pile body's end. With its ingenious threaded design, it ensures robust force transmission, exceptional resistance to pull-out and shear, and offers seamless construction ease. Below, we delve into a comprehensive exploration of its functional positioning, structural classification, technical parameters, application scenarios, selection principles, and common problems along with their solutions.

The Core Functionality of Pile Head Wire

1. Mechanical Connection and Force Transmission

Through expertly crafted threaded engagement, the pile body—be it precast concrete piles or steel pipe piles—is securely connected to the bearing platform, adapter, or anchoring device, ensuring synchronized force-bearing within the pile bearing platform system.

Data: The innovative threaded connections boast an efficacy rate exceeding 90%, dramatically outperforming traditional methods like welding or grouting, which typically range between 60% to 70%.

Example: In the sophisticated single pile foundation used in offshore wind power, the connection between the pile head wire and the flange admirably withstands a vertical load of 1000 tons and a horizontal shear force of 50 tons.

2. Anti Pull and Anti Shear Reinforcement

The uniquely designed thread profiles, such as trapezoidal or serrated threads, remarkably enhance the frictional resistance between the pile and the surrounding soil or concrete, making them ideal for scenarios like anti-floating and anchor piles.

• Testing: The pull-out bearing capacity of threaded pile heads is impressively 3-5 times higher compared to smooth pile heads, exemplified by an increase in pull-out capacity from 200 tons to a staggering 600-1000 tons for a pile with an 800mm diameter.

3. Optimization of Construction Efficiency

By eliminating the need for on-site welding, grouting, and similar processes, installation is simplified to a twist mechanism, effectively reducing the construction period by more than 50%.

Case: In a 30-story residential project leveraging prefabricated pipe piles and threaded pile heads, the foundation construction timeline was impressively shortened from 45 days to just 20 days.

4. Quality Controllability

Factory-prefabricated threads guarantee precise tooth profile accuracy (with a pitch error of no more than ±0.1mm), thereby preventing connection failures that commonly arise due to on-site construction inaccuracies.

Comparison: While manually engraved threads on-site have a qualification rate of merely 70%, prefabricated threads boast a remarkable qualification rate exceeding 99%.
