The invention discloses a high-performance low-prestressed concrete hollow square pile. The high-performance low-prestressed concrete hollow square pile is characterized in that a pile body is composed of at least one unit pile; each unit pile is composed of concrete and parallel reinforcing steel bars tensioned with the prestress of 0.3-0.6 [sigma] in the concrete; the two ends of the reinforcing steel bars are connected with connection plates respectively; the adjacent unit piles are welded through the connection plates to form the pile body; the outer layers of the two connected connection plates are coated with fiber resin with the thickness not smaller than 1.5 mm; the fiber resin layers are wrapped with carbon fiber cloth capable of improving the antiseptic ability and tension resistance. The high-performance low-prestressed concrete hollow square pile has the advantages of being high in corrosion resistance, large in bearing force, low in production cost, high in durability and the like, the problem of the piling illusion is effectively solved, the integrity of the pile body is ensured during construction, the bearing force of the pile body is effectively improved, the weight is lower, cracks caused by mutual collision in the production and transportation process can be avoided, and the phenomena of pile breakage, pile body concrete falling and the like are also not prone to occurring in the site construction.
