Anti-pull piles are widely used in large basement anti-floating, high-rise buildings (structures) anti-pull, anti-pull of offshore pier platforms, anchor pile foundations of suspension bridges and cable-stayed bridges, pile foundations of large dock floors and static load test piles Anchor pile foundation and so on.
The original design of the golden home anti-pull pile was 15 meters high and 600 mm in diameter, the main diameter of the reinforcing cage was 20 mm, the number was 16 pieces, the stirrups were 8 mm, and the stiffeners and positioning ribs were 14 mm. Using GFRP material equivalent replacement, the direct cost is about 3135.2 yuan. Using GFRP material and other strong substitutes (12 main bars), the direct cost is about 3063.9 yuan.
In summary, the equivalent replacement of steel bars with GFRP materials can reduce direct costs by about 12%. The overall cost can be saved by 17%.
Equal strength replacement can reduce direct costs by about 14%, and comprehensive costs can be saved by 21%.
