Prestressed concrete pipe pile and processing method thereof
The invention relates to the technical field of foundation construction, in particular to a prestressed concrete pipe pile and a machining method thereof. The invention provides a prestressed concrete pipe pile. The prestressed concrete pipe pile comprises a pile body, an end plate and a pile tip. The pile tip comprises a concrete cone and an auxiliary reinforcement cage. The auxiliary reinforcement cage is arranged in a pyramid shape, and a connector is arranged on the auxiliary reinforcement cage and fixedly connected with the end plate. The invention further provides a machining method of the prestressed concrete pipe pile. A pipe pile centrifugal machine and a steel mold are adopted. The steel die comprises a main die and an auxiliary die; the auxiliary reinforcement cage is fixedly connected with the end plate, the end plate is installed between the main mold and the auxiliary mold and fixedly connected with the auxiliary mold, and the auxiliary reinforcement cage is arranged in the auxiliary mold; and filling concrete into the main mold, closing the mold and centrifugally forming. The pile tip and the end plate are connected into a whole, the shear resistance among the end plate, the pile body and the pile tip is improved through the shear-resistant column or the shear-resistant sleeve, the overall strength of the prestressed concrete pipe pile is effectively improved, and therefore the pile sinking precision is improved.
本申请涉及地基施工的技术领域，尤其是涉及一种预应力混凝土管桩及其加工方法。本申请提供一种预应力混凝土管桩，包括桩身、端板、桩尖；桩尖包括混凝土锥体以及副钢筋笼；副钢筋笼呈角锥状设置，副钢筋笼上设置有接头，接头与端板固定连接。本申请还提供一种预应力混凝土管桩的加工方法，采用管桩离心机和钢模；钢模包括主模和副模；副钢筋笼与端板固定连接，端板安装在主模和副模之间并与副模固定连接，副钢筋笼置于副模内；向主模内填充混凝土后合模并离心成型。桩尖与端板连为一体，并且通过抗剪柱或抗剪套筒以增加端板、桩身、桩尖之间的抗剪性能，有效提升预应力混凝土管桩的整体强度，由此提升沉桩精度。
