Pre-stressed concrete piles (PC) and pre-stressed high strength concrete piles (PHC) are produced an accordance with standard TCVN 7888:2014
Nodular pile is a prestressed centrifugal concrete pile with a new design (ribbed shape on concrete pile) to improve the friction and loading capacity of concrete piles.
Concrete square piles are applied according to design standards: TCVN 5574: 2012 "Concrete & reinforced concrete structures - Design standards", 22TCN272-05 "Design standards", ACI 318 "Construction requirements for structural concrete".
There are 2 methods of pressing pile construction with counterbalance: Mechanical pressing and self-propelled robot pressing.
