Prefabricated pipe pile capable of improving vertical bearing capacity of pile bottom
The invention provides a prefabricated pipe pile capable of improving the vertical bearing capacity of a pile bottom. The prefabricated pipe pile comprises a hollow pile body, wherein the inner diameter of the upper portion of the pile body is the same, and the inner diameter of the lower portion of the pile body is gradually reduced from the position away from the height of the pile bottom to the pile bottom. According to the prefabricated pipe pile, the stress area of concrete at the pile bottom of the prefabricated pipe pile is increased, and therefore the vertical bearing capacity of the pile bottom of the prefabricated pipe pile is improved; and in other words, when the prefabricated pipe pile is manufactured, the upper portion and an existing prefabricated pipe pile are kept unchanged, the concrete part is gradually increased from the position h away from the bottom of the prefabricated pipe pile to the pile bottom of the pipe pile, the thickness t of the obtained prefabricated pipe pile is increased compared with the thickness of concrete at the pile bottom of the existing prefabricated pipe pile, the stress area of the concrete at the pile bottom of the prefabricated pipe pile is increased accordingly, and therefore the vertical bearing capacity of the pile bottom of the prefabricated pipe pile is improved.
本发明提供一种可提高桩底竖向承载力的预制管桩，包括中空的桩体，所述桩体的上部的内径相同，所述桩体的下部从距离桩底高度处至桩底的内径逐渐缩小。本发明通过提高预制管桩桩底部混凝土受力面积，从而提高预制管桩桩底竖向承载力，即在做预制管桩时，保持上部与现有预制管桩不变，从距预制管桩底部h处开始逐渐加大混凝土部分，直至管桩桩底，得到的预制管桩较以往预制管桩桩底混凝土厚度增大t，预制管桩桩底混凝土受力面积也随之增大，从而提高预制管桩桩底竖向承载力。
