Abstract
The invention discloses a prefabricated PHC tube pile. The prefabricated PHC tube pile comprises a pile body manufactured through a pre-tensioning pre-stressing process and a centrifugal molding method and a pile body inner cavity defined by the pile body. A steel reinforcement cage weaved through steel bars is arranged in the pile body inner cavity. A first grouting tube and a second grouting tube are inlaid in the end faces of the two opposite sides in the pile body correspondingly. The first grouting tube and the second grouting tube both penetrate through the whole pile body. Sealing plugs are plugged at ports, located in the end face of one side of the pile body, of the first grouting tube and the second grouting tube. A steel pile cap is mounted on the surface of a port of the end, provided with the sealing plugs, of the pile body in a clamped mode. A pile toe is connected to the end face of the side, different from the side where the sealing plugs are located, of the pile body in a matched mode. The prefabricated PHC tube pile is reasonable in structural design. According to the tube pile, grouting is conducted through a first grouting hole and a second grouting hole located in one side of the pile body, and the manufacturing speed of the whole PHC tube pile is increased. Grouting is conducted through a grouting head guide tube to guarantee the airtightness of connection between a grouting machine and the grouting holes in the grouting process.
