Sleeve joint pile and pile sinking method thereof
The invention relates to a socket pile and a pile sinking method thereof, and belongs to the technical field of foundation construction. The socket pile comprises a plurality of sections of sleeves and a one-way locking assembly. The multiple sections of sleeves are sequentially arranged in a sleeving mode from inside to outside, in every two adjacent sections of sleeves, the sleeve located on the outer layer can be lifted relative to the sleeve located on the inner layer in the axial direction, and a pile tip is formed at the bottom end of the sleeve located on the innermost layer; the one-way locking assembly is connected between every two adjacent sleeves and used for limiting the falling movement of the outer sleeve relative to the inner sleeve in the axial direction. The pile length of the socket pile can be stretched according to needs so as to increase the pile sinking depth, and the socket pile can be suitable for the working condition that the pile length and the pile sinking depth cannot be determined in advance.
本发明涉及一种套节桩及其沉桩方法，属于基础施工技术领域。该套节桩包括多节套筒和单向锁止组件；多节套筒由内至外依次套设，每相邻两节套筒中，位于外层的套筒可沿轴向相对于位于内层的套筒提升，位于最内层的套筒的底端形成桩尖；单向锁止组件连接于相邻两节套筒之间，用于限制外层套筒沿轴向相对于内层套筒的下落运动。本发明提供的套节桩的桩长可按需拉伸以增加沉桩深度，能够适用于无法事先确定桩长和沉桩深度的工况。
