Construction method of super-long prestressed pipe pile for compacting sand layer
The invention discloses a construction method of an ultra-long prestressed pipe pile for compacting a sand layer, which comprises the following steps of: dividing the ultra-long prestressed pipe pile into a plurality of section piles, and numbering from bottom to top; piling and splicing the piles at the same time until the super-long prestressed pipe pile is formed; sinking the super-long prestressed pipe pile to the designed depth of the bottom; earth is excavated to the designed elevation of the top of the super-long prestressed pipe pile; the part, located above the top design elevation, of the super-long prestressed pipe pile is cut off; a high-pressure water gun is used for conducting pile core soil cleaning on the super-long prestressed pipe pile, and the pile core soil cleaning is stopped when the pile core soil cleaning is conducted to the connecting point of the two uppermost section piles; water in the pile core is discharged through a water suction pump; and a reinforcement cage is hoisted to the pile core, concrete pouring is conducted, and the construction efficiency is improved by adopting the construction method of the super-long prestressed pipe pile.
本发明公开了一种用于密实砂层的超长预应力管桩的施工方法，包括步骤：将所述超长预应力管桩分割成多段节桩，并自下而上进行编号；一边打桩一边接桩直到形成所述超长预应力管桩；将所述超长预应力管桩向下沉桩直到底部设计深度；土方开挖至所述超长预应力管桩的顶部设计标高；将所述超长预应力管桩位于顶部设计标高以上的部分截断；利用高压水枪对所述超长预应力管桩进行桩芯清土，并在清至最上方两节所述节桩的连接点时停止；利用抽水泵将桩芯内的水排出；将钢筋笼吊装至所述桩芯并进行混凝土浇筑，通过采用所述超长预应力管桩的施工方法，提高了施工效率。
