Precast prestressed concrete driven pile
Terratest
Typical reinforcement is 8 pre-tensioned steel strands of 0.5” section as longitudinal reinforcement and transverse reinforcement made up of rings of 6 to 10 cm. diameter at the ends of the pile.
Pre-tensioned, pre-fabricated piles are especially suitable for installation in very soft soils where significant tensile stress may be exerted during pile driving.
Applications:
Structures (bridges and viaducts)
Multi-storey buildings or edifices in seismic areas where foundations are subjected to significant buckling stress.
Structures and buildings where the lowest elevation is below the water table, so that the piles are subjected to tensile stress due to under-pressure.
Retention of earthwork embankments, basements, etc., (pile wall).
Industrial buildings with significant horizontal or buckling stress.
As for Prefabricated Reinforced Piles, the quality of these Pre-tensioned Pre-fabricated piles is monitored both at the factory and on the building site (PDA, static and dynamic load testing, vibration control).
