Prefabricated square pile for supporting deep foundation pit and side slope and pile splicing method of prefabricated square pile
The invention discloses a prefabricated square pile for supporting a deep foundation pit and a side slope and a pile splicing method of the prefabricated square pile. The prefabricated square pile comprises a solid prefabricated square pile body, the prefabricated square pile is provided with a plurality of anchor cable holes vertical to the pile body of the prefabricated square pile along the length direction, and the plurality of anchor cable holes are all positioned on the central line of the prefabricated square pile, and the anchor cable holes do not interfere with main reinforcements andwinding reinforcements of the prefabricated square pile. The anchor cable holes are threaded holes, the inner diameter of each anchor cable hole is 180 mm, and the distance between every two adjacentanchor cable holes is 2000-4000 mm. The cross section of the prefabricated square pile is square, hoop-wrapping joints with certain lengths are reserved at two ends of the prefabricated square pile,the end faces of the two ends of the prefabricated square pile are provided with butt-joint end steel plates and butt-joint hoop plates matched with the butt-joint end steel plates and the hoop-wrapping joints, and the butt-joint hoop plates are wrapped and tightly attached to the hoop-wrapping joints and the butt-joint end steel plates. The cross sections of the hoop-wrapping joints and the butt-joint end steel plates are square, end plate holes are formed in each butt-joint end steel plate, and the butt-joint hoop plates are formed by fixedly connecting two L-shaped steel plates with the same specification in a butt joint way. The prefabricated square pile meets the strength requirement, has low cost, and is safe and environment-friendly.
本发明公开了一种用于深基坑及边坡支护的预制方桩及其接桩方法，包括实心的预制方桩，预制方桩沿其长度方向上设有多个垂直于其桩身的锚索孔，且多个锚索孔均位于预制方桩的中心线上，锚索孔不与预制方桩的主筋及绕筋干涉。锚索孔为螺纹孔，其内径为180mm，相邻两锚索孔相距2000～4000mm。预制方桩的截面是正方形，其两端均预留一定长度的包箍接头，预制方桩两端端面处设有对接端钢板以及与对接端钢板、包箍接头匹配的对接箍板，对接箍板包覆并紧贴包箍接头和对接端钢板。包箍接头和对接端钢板的截面均是正方形，对接端钢板上设有端板孔，对接箍板由两个规格相同的L型钢板对接固定形成。满足强度要求、成本低、安全环保。
