Anti-scouring pile foundation
The anti-scouring pile foundation comprises a pile foundation body and anti-scouring parts, the upper end of the pile foundation body is located in seawater above a seabed surface, the lower end of the pile foundation body is pre-buried in gravel below the seabed surface, and the anti-scouring parts are arranged on the pile foundation body in a penetrating mode; the anti-scouring piece can move in the vertical direction relative to the pile foundation under the action of the self weight of the anti-scouring piece so that when a scouring pit appears around the pile foundation, the anti-scouring piece can move downwards to fill the scouring pit, the anti-scouring piece comprises a first section and a second section, the first section is arranged above the second section and connected with the second section, and the second section is arranged above the first section. The cross sectional area of the peripheral surface of the first section is gradually reduced from bottom to top, so that when the anti-scouring piece is impacted by seawater, the impact force of the seawater moves upwards, and the cross sectional area of the peripheral surface of the second section is gradually reduced from top to bottom, so that when the anti-scouring piece is filled in the scouring pit, the second section is arranged in sand below the seabed surface in a penetrating manner. The anti-scouring pile foundation has the advantages of being simple in structure, long in service life and the like.
本发明公开了一种抗冲刷的桩基础，所述抗冲刷的桩基础包括桩基础和抗冲刷件，桩基础的上端部位于海床面上方的海水中，桩基础的下端部预埋在海床面下方的砂石中，抗冲刷件穿设在桩基础上，抗冲刷件在其自重的作用下可相对于桩基础沿上下方向可移动，以在桩基础周围出现冲坑时，抗冲刷件可向下移动以填充冲坑，抗冲刷件包括第一段和第二段，第一段设在第二段的上方且与第二段相连，第一段的外周面的横截面积从下到上逐渐减小，以在抗冲刷件受到海水冲击时，海水冲击力向上运动，第二段的外周面的横截面积从上到下逐渐减小，以在抗冲刷件填充在冲坑内时，第二段穿设在海床面下方的砂石中。本发明的抗冲刷的桩基础具有结构简单、使用寿命长等优点。
