Pile foundation casing and construction method of cast-in-place pile
The pile foundation protection cylinder comprises a first protection cylinder wall and a second protection cylinder wall which are used for defining the pile foundation protection cylinder, an open groove is formed in the first protection cylinder wall and penetrates through the first protection cylinder wall in the axial direction of the first protection cylinder wall, the second protection cylinder wall is embedded in the open groove, and the first protection cylinder wall and the second protection cylinder wall are connected through the open groove. The second pile casing wall is arranged on the first pile casing wall and can slide along the open groove, and a positioning structure used for fixing a concrete guide pipe is arranged at the top end of the second pile casing wall, so that in pile foundation construction, when the first pile casing wall is lifted, the height positions of the second pile casing wall and the concrete guide pipe are not changed, concrete shrinkage can be supplemented in time, operation is convenient, the construction difficulty is small, and the construction efficiency is improved. Time and labor cost can be saved, and construction efficiency is remarkably improved.
本发明公开了一种桩基护筒及灌注桩的施工方法，包括用于围成所述桩基护筒的第一护筒壁和第二护筒壁，所述第一护筒壁上开设有开槽，所述开槽沿所述第一护筒壁的轴向方向贯通所述第一护筒壁，所述第二护筒壁嵌设于所述开槽内，且可沿所述开槽滑动，所述第二护筒壁的顶端上布设有用于固定混凝土导管的定位构造，以使得在桩基施工中，提升所述第一护筒壁时，所述第二护筒壁及所述混凝土导管的高度位置不变，能及时补充混凝土缩量，操作方便，施工难度小，能节约时间及人力成本，显著提升施工效率。
