Concrete prefabricated pipe pile with prefabricated step slope at pile top for overhead transmission line
The invention discloses a concrete prefabricated pipe pile with a pile top prefabricated step slope for an overhead transmission line, relates to the field of power construction, and solves the problems that in the prior art, when an anchoring short steel bar is pre-buried in a pipe pile body, machining is tedious, and foundation bolts in the patent are only simply fixed in concrete, so that the construction cost is low. The foundation bolt comprises a prefabricated pipe pile, and a pile bottom section and a pile top section are sequentially arranged in the prefabricated pipe pile from top to bottom; the step-shaped slopes are formed on the inner wall of the prefabricated pipe pile through a prefabrication forming method, compared with the mode that anchoring short steel bars are pre-buried in the prefabricated pipe pile, machining is more convenient, the adjustable cage body is fixed between the step-shaped slopes, and after the foundation bolts are fixed to the adjustable cage body through the height adjusting rings, the foundation bolts are fixed to the adjustable cage body through the height adjusting rings. And concrete is cast between the adjustable cage body and the pile top section, so that the contact area between the foundation bolt and the concrete is increased in a disguised manner, and the fixing strength is improved.
本发明公开了一种架空输电线路用桩顶预制台阶斜面的混凝土预制管桩，涉及电力施工领域，解决了现有技术中在向制管桩主体内预埋锚固短钢筋时，加工较为繁琐，并且上述专利中的地脚螺栓只是简单的固定在混凝土中，与混凝土的接触面积不足，无法保证地脚螺栓的固定强度的问题，包括预制管桩，预制管桩内自上而下依次设置桩底段和桩顶段；本发明通过预制成型的方法在预制管桩的内壁上形成台阶型斜面，相对于在预制管桩内预埋锚固短钢筋，加工更加方便，并且在台阶型斜面之间固定有可调节笼体，将地脚螺栓通过高度调节环固定在可调节笼体上后，在可调节笼体与桩顶段之间浇铸有混凝土，从而变相增大地脚螺栓与混凝土的接触面积，增加其固定强度。
