ICP Piles

ICP piles is another type of piling, it’s also known as Pretensioned Spun High Strength Concrete Piles (ICP PHC Piles) which offer an economical foundation system with consistent and superior quality compared to the ordinary concrete piles.

ICP Piles are circular in cross-section and are manufactured in sizes ranging from diameter 250mm to 1200mm with standard lengths varying from 6m to 46m in single pieces. ICP Piles can be easily joined to any combination of length as per design requirement. ICP piles are manufactured with steel end plates for splicing.

Today, with the state-of-the-art autoclave curing system, ICP Piles can be installed immediately after autoclaving. ICP piles have been used extensively as foundation piles for power stations, highrise buildings, civil engineering works, bridges, marine structures, harbours, schools and government project, etc.

Materials For ICP Piles

1) Aggregates
Coarse aggregates shall be 20mm granite. Fine aggregates shall be clean river sand or washed mining sand.

2) Cement
Ordinary Portland cement.

3) Prestressing Steel
High frequency induction heat treated bars.

4) Spiral wire
Hard drawn wire.

Joint

The joint is designed to have the same performance as the main body particularly in respect of bending strength. All ICP piles will be supplied with steel extension plates for splicing.

Lifting Points

Two lifting point will be marked on all piles exceeding 9m. No special lifting bolt or wire rope is cast into the piles. Lifting is by wrapping wire ropes round the piles at specified points.

Pile Shoes

All ICP Piles will be supplied either open ended, with a flat shoe or with an X-pointed shoe.

Curing

After casting, the piles are steam cured. When the concrete reaches the specified transfer strength, the piles are demoulded, marked and checked for quality. The piles can normally be transported and driven when the cube strength reaches 50 N/mm2. Today with the state-of-the-art autoclave curing system, the piles can be installed immediately after autoclaving.
