Characteristics of PHC pile:
(1) in strict accordance with the national standard and Japan standard, the concrete strength grade is not less than C80 grade.
(2) the bearing capacity of single pile is high and the design range is wide. In the same building, pipe piles with different diameters can be used to solve the pile problem easily, and the bearing capacity of each pile can be fully played.
(3) the single school can be connected to any length without the limitation of the construction machinery and construction conditions.
(4) the quality of the pile forming is reliable, the length of pile and the quality of the pile can be monitored by direct means.
(5) the pile body is resistant to hammer and crack resistance, and the penetration is strong.
(6) low cost. The unit bearing capacity is only 1/3-2/3 of steel pile, and the steel is saved.
(7) fast construction and civilized construction.
