Buildings, piled embankments, bridges, ports and marine structures (able to produce up until 50m single length without jointing).
Retaining and quay walls.
Prefabricated construction of building and marine structure.
Centrifugal method of pile forming produces high strength dense concrete which results in larger bearing capacity for the same given section.
The effects of prestressing, geometry of section and high strength concrete give rise to large bending moment capacity.
The effect of prestressing prevents cracking in the piles. Even if cracking may occur due to a temporary excessive load, it will disappear as soon as the load is removed so that full protection of the prestressing bars from corrosion is assured. The high concrete density also has high resistance to sulphate attack.
On completion of welding work, the welded joint becomes instantaneously as strong as the pile body. Moreover, the joint welding work can be done by utilizing fully automatic welding methods. This is also to ensure that the full strength of weld is produced.
Various kinds of installation methods which have significant sound and vibration effects have been developed to adapt to different types of environment.
Spun concrete compressive strength of 80N/mm² is achieved and hence improve the overall structural strength of piles such as allowable axial load capacity, tensile capacity and bending capacity.
CEPCO PHC Piles can be driven to much harder bearing strata to achieve higher bearing capacity. This results in overall saving in the foundation cost.
Overall quality of piles is further improved particularly resistance to corrosion and sulphate attack due to further reduction in the permeability of the concrete.
CEPCO PHC Piles are ready for driving earlier than the normal piles due to the higher concrete compressive strength being achieved.
