Precast pile capable of eliminating excess pore water pressure and manufacturing method
The invention discloses a precast pile capable of eliminating excess pore water pressure and a manufacturing method. The precast pile comprises a precast pile body, a vertical guide pipe and a circumferential guide pipe, wherein the vertical guide pipe is arranged in the length direction of the precast pile body; the circumferential guide pipe is arranged on the circumferential outer surface of the precast pile body; the circumferential guide pipe communicates with the vertical guide pipe located on the outer surface of the precast pile body; and permeation holes are distributed in the surface of the vertical guide pipe and the surface of the circumferential guide pipe. The vertical guide pipe and the circumferential guide pipe which are connected in series are arranged on the precast pile body, when the precast pile is constructed and pressed to a soil body, pore water in the soil body can enter the vertical guide pipe and the circumferential guide pipe through the permeation holes in the surfaces of the vertical guide pipe and the circumferential guide pipe, a rapid permeation channel is formed, and therefore the pile forming difficulty caused by the excess pore water pressure is eliminated. The precast pile is simple in structure, easy to machine and manufacture, easy to maintain, high in safety and easy to produce in batches and has great market popularization value.
本申请公开一种可消除超孔隙水压力的预制桩及制作方法，包括：预制桩本体、竖向导管和环向导管；所述竖向导管设于所述预制桩本体的长度方向；所述环向导管设于所述预制桩本体的环向外表面；所述环向导管与位于所述预制桩本体外表面的竖向导管连通；其中，所述竖向导管表面和所述环向导管表面均分布有渗透孔。通过在预制桩本体上设置串联的竖向导管和环向导管，施工预制桩压至土体时，土体中的孔隙水可以通过竖向导管和环向导管表面的渗透孔进入竖向导管和环向导管内，形成快速的渗流通道，从而消除超孔隙水压力造成的成桩困难。该结构简单，易于加工制造、维修容易、安全性高、易于批量生产，具有极大的市场推广价值。
