Full-follow-up cast-in-place pile casing
The invention discloses a full-follow-up cast-in-place pile casing. The pile casing comprises a main guide pipe, a sleeve lower connector and a sleeve upper connector which are wielded and machined together; the sleeve upper connector is arranged at one end of the main guide pipe; the sleeve lower connector is arranged at the other end of the main guide pipe; the adjacent pile casings are in butt joint through the sleeve upper connectors and the sleeve lower connectors; the sleeve upper connector and the sleeve lower connector are provided with positioning bolt holes and positioning parts; a flow hole is formed in the pipe wall of the main guide pipe; a slurry air inlet of the flow hole is formed in the sleeve upper connector of the pile casing; and a slurry air outlet of the flow hole is formed in the sleeve lower connector. The full-follow-up cast-in-place pile casing is simple in structure; the pile casing is integrally connected and combined through splicing of a plurality of module pile casings; and a rotary pressurizing grouting implanting method and splicing combined construction of the pile casings are combined, so that energy is saved, the environment is protected, operation is easy, and the construction efficiency is improved.
本发明公开了全跟进灌注桩护筒，全跟进灌注桩护筒，所述护筒包括主导管、套筒下接头以及套筒上接头焊接加工组成,所述主导管的一端为套筒上接头，主导管的另一端套筒下接头，相邻的护筒通过套筒上接头和套筒下接头对接，所述套筒上接头和套筒下接头上设有定位螺栓孔和定位件，主导管的管壁上设有流量孔，流量孔的进浆气口设置在护筒的套筒上接头，所述流量孔的出浆气口设置在套筒下接头;本发明结构简单，通过多个模块护筒拼接，实现护筒整体含接组合，结合旋转加压注浆植入法与护筒的拼接组合施工，节能环保，操作简单，提高施工效率。
