Prestress section steel construction method pile structure capable of controlling deformation
The invention relates to a prestress section steel construction method pile structure capable of controlling deformation. Section steel is arranged in a three-axis cement mixing pile, and is formed bywelding H-shaped steel, prestress steel sleeves are welded to the inner side of a flange at one side close to a pit, of the H-shaped steel, a full-length steel plate is welded to the end of the flange of the H-shaped steel to be used as a reinforcing structure, and the full-length steel plate is parallel to an H-shaped steel web to form a box-shaped structure. A steel plate is arranged at the bottom end of the H-shaped steel. Prestress steel strands are connected into inner pipes of the prestress steel sleeves in a penetrating mode and extend in the axial direction of the prestress steel sleeves, one ends of the prestress steel strands are fixed to the steel plate at the bottom end of box-shaped steel, and the other ends of the prestress steel strands penetrate through the top ends of theprestress steel sleeves to be subjected to steel strand prestress tensioning and then are fixed to a prestress locking device of a concrete coping ring beam. By the adoption of the novel prestress section steel construction method pile structure capable of controlling deformation, the rigidity, bending resistance, shearing resistance and deformation resistance of construction method pile sectionsteel can be enhanced.
本发明涉及一种控制变形的预应力型钢工法桩结构，三轴水泥土搅拌桩中设置有型钢；所述型钢由H型钢焊接而成，所述H型钢临坑侧的翼缘内侧焊接有预应力钢套管，所述H型钢翼缘端部焊接通长钢板作为加强构造，通长钢板与H型钢腹板平行，形成箱型结构；所述H型钢底端设置有钢板；所述预应力钢套管内管中穿接有预应力钢绞线，所述预应力钢绞线沿预应力钢套管作轴向伸展，其中，一端固定于箱型型钢底端的钢板，另一端穿过预应力钢套管的顶端进行钢绞线预应力张拉后固定于混凝土压顶圈梁的预应力锁定器。采用本发明的控制变形的新型预应力型钢工法桩结构可加强工法桩型钢的刚度以及抗弯、抗剪及抗变形能力。
