PRECAST PILES

Procedure

The piles are driven with modem, free-fall equipment, using a hammer of between 5 and 9 tons raised either by a simple cable system, or the most advanced hydraulic drive methods with high performance and controls. This equipment is completely autonomous (requiring no auxiliary components) and mounted on crawler-cranes for easy movement.
Precast square elements are joint together with special keys (ABB seal) designed by Kharrl Tech technical department. The ABB seal is the element allowing the union of different pile sections. to reach the necessary depth. These seals are made with high-quality materials. and calculated to bear greater stresses even that the pile's standard section, as demonstrated in bending, compression and traction trials

Applications

Precast piles are especially utilized for their low cost advantages, for sites in remote areas and for foundations with contained vertical loads applied.

Precast prestressed piles Applications

Because of the initial prestress force, KHARRL TECH's precast prestressed piles are particularly indicated for the absorption of traction and bending strains and horizontal thrust, giving foundations that are more economical than other designs.

The following may be highlighted, among other applications.

• Structures (bridges and viaducts).
• Tall buildings or those situated in earthquake zones.
• Structures and buildings where the ground floor or basement levels are below the water table.
• Contention of walls, basements, etc.
• Industrial buildings with significant horizontal or pending stresses.
