Prestressed Concrete Piles
BS 8110 and BS 8004

General Specifications
1. PRESTRESSING
Longitudinal wires are stressed to between 70%
and   80%  of   its characteristic breaking stress.
Average  loss of  prestress is 18%.
2. CHARACTERISTIC STRENGTH
for concrete is  60 N/mm˛.
3. BREAKING STRESS
of  prestressing wires is 1770 N/mm˛.

Oka Prestressed Piles
OKA-piles being used at site.
4. ALLOWABLE AXIAL WORKING LOAD
Normal  conditions  for actual   load are  based on soil conditions and should  be
determined by load test.  The normal allowable axial working  load recommended   represents  the structural  capacity of  the  piles.
5. PILE JOINT
Piles comes with end  plate  jointing and welding are required  to effect  the piles
jointing.
6. LIFTING
OKA - piles are  provided  with  2  lifting   hooks  incorporated  in  the  pile at  0.2
times of  the pile  length  from  each  end.    This  ensures minimum  lifting  stress.
