The invention relates to a PHC tubular pile for post-grouting. The PHC tubular pile comprises a pile body and a pile body inner cavity defined by the pile body, a plurality of grouting holes communicating with the pile body inner cavity are formed in the pile body, and a plugging plate is movably attached to the position, where the grouting holes are formed, of the outer side wall of the pile body; the plugging plate is slidably arranged in the direction parallel to the radial line of the pile body to the direction away from the grouting holes, a plurality of pile side grouting pipes corresponding to the grouting holes one to one are embedded in the pile body, one ends of the pile side grouting pipes extend out of the pile body, and the other ends of the pile side grouting pipes extend tobe attached to the positions of the grouting holes in the inner wall of the pile body; and a traction assembly which can enable the plugging plate to be attached to the outer side wall of the pile body and can be separated from the outer side wall of the pile body under the pushing of slurry is arranged between the pile body and the pile side grouting pipes. According to the PHC tubular pile, slurry can permeate into pores of a supporting layer on the pile side from the grouting holes of the pile body, and therefore the effect of a reinforcing body is effectively achieved.
本申请涉及一种用于后注浆的PHC管桩，包括桩体和由桩体围成的桩体内腔，所述桩体上开设有若干个连通桩体内腔的注浆孔，所述桩体外侧壁上于注浆孔的位置处活动贴合有封堵板，所述封堵板沿平行于桩体径线方向向远离注浆孔的方向滑动设置，所述桩体内部内嵌有若干根与若干个注浆孔一一对应的桩侧注浆管，所述桩侧注浆管的一端延伸出桩体外、另一端延伸至与桩体内壁上注浆孔的位置处相贴合，所述桩体与桩侧注浆管之间设置有能使封堵板贴合于桩体外侧壁且能在浆液的推动下与桩体外侧壁分离的牵拉组件。其能够可以使浆液从桩体的注浆孔位置处渗透到桩侧的持力层孔隙中，从而有效的形成加固体的效果。
