Stabilization post-grouting device suitable for vibration immersed tube cast-in-place pile
The invention relates to the field of civil construction equipment, in particular to a stable post-grouting device suitable for a vibration immersed tube cast-in-place pile, which comprises a pile body and a pile tip, the pile tip is provided with a grouting cavity, the side wall of the pile tip is provided with a grouting hole communicated to the grouting cavity, the pile tip is provided with an annular bag on the upper side of the grouting hole, and the annular bag is communicated with a grouting pipeline; wherein the annular bag can stretch out and draw back to the surface side of the pile tip, the annular bag can expand out of the surface side of the pile tip after grouting, the annular bag is arranged, a grout stopping structure can be formed through the annular bag before one-time grouting, sealing of a grouting hole is reduced, and the problems existing in the prior art are effectively solved.
本发明土建施工设备领域，尤其是一种适用于振动沉管灌注桩的稳定后注浆装置，包括桩身和桩尖，所述桩尖设有注浆腔，所述桩尖的侧壁设有连通至所述注浆腔的注浆孔，所述桩尖在所述注浆孔的上侧设有环囊，所述环囊连通有注浆管道；其中，所述环囊能够伸缩于所述桩尖的表侧，在所述环囊在注浆后能够膨胀出所述桩尖表侧，本发明通过设置了环囊，可以在一次注浆前通过环囊形成止浆结构，减少对注浆孔处的封闭，有效的解决了现有技术中存在的问题。
