Embodiment 1
[0028] (1) Drilling: Position the pile hole, use the drilling machine to drill a pile hole with a diameter 10cm larger than the diameter of the pipe pile at the required pile position in the foundation, drill to the design hole depth, move the drilling machine out of the pile hole, and clear the hole residues in
[0029] (2) Concrete injection: concrete is poured into the root of the pile hole through the grouting pipe, and the concrete is C25 concrete;
[0030] (3) Pile planting: insert the prepared PHC pipe pile with a specification of 500mm into the pile hole filled with concrete, insert a section of pipe pile, and the concrete goes upward along the pipe wall of the pipe pile and the gap between the pipe pile and the pile hole After the pile is moved, the concrete solidifies and forms.
Embodiment 2
[0032] (1) Drilling: Position the pile hole, use the drilling machine to drill a pile hole with a diameter 10cm larger than the diameter of the pipe pile at the required pile position in the foundation, drill to the design hole depth, move the drilling machine out of the pile hole, and clear the hole residues in
[0033] (2) Concrete injection: concrete is poured into the root of the pile hole through the grouting pipe, and the concrete is C35 concrete;
[0034] (3) Pile planting: Insert the prepared combined pile of PHC and steel pipe pile with a specification of 1000 into the pile hole filled with concrete, insert two sections of pipe piles in sequence, and the concrete will be along the pipe wall of the pipe pile and the pipe pile and the pile. The gap between the holes moves upward, and the concrete solidifies and forms after the pile is completed.
