Reducing prefabricated pipe pile
The invention relates to the technical field of building construction, in particular to a variable-diameter prefabricated tubular pile which comprises a connector, a concrete prefabricated pile and a variable-diameter pile body which are sequentially connected from top to bottom and coaxially connected. The connecting body, the concrete precast pile and the variable-diameter pile body are hollow cylinders which are provided with cavities and are communicated with one another, and the cavities of the connecting body are matched with the variable-diameter pile body in shape so as to realize combined installation; the variable-diameter pile body comprises a variable-diameter part, a pile body and a pile tip part; the upper half part of the cavity of the reducing part is in a circular truncated cone shape, the diameter of the upper end is the same as that of the cavity of the concrete precast pile, the middle part of the cavity is cylindrical, and the lower half part of the cavity is in an inverted circular truncated cone shape and is symmetrical to the circular truncated cone shape of the upper half part of the cavity; the cavity of the variable-diameter pile body penetrates to the lower bottom face of the pile tip part, and a pile tip is arranged on the lower bottom face of the pile tip part. The problems that the depth of a pile body entering a preset bearing layer is limited, the pulling resistance is poor, and potential safety hazards are caused to a foundation of a building can be solved.
本发明涉及建筑施工技术领域，具体涉及一种变径预制管桩，包括从上到下依次连接设置的连接体、混凝土预制桩和变径桩身，并同轴连接；所述连接体、混凝土预制桩和变径桩身均为具有空腔且相互连通的空心柱体，所述连接体的空腔与变径桩身的外形相匹配以实现组合安装；所述变径桩身包括变径部、桩身和桩尖部；变径部的空腔上半部为圆台形状且上端直径与混凝土预制桩空腔的直径相同，其空腔中部为圆柱形状，其空腔下半部为倒圆台形状且与空腔上半部的圆台形状相对称；变径桩身的空腔贯穿至桩尖部的下底面，桩尖部的下底面上设置有桩尖。本发明能够解决桩身进入预定持力层深度较为有限，以及解决了抗拔性能较差，给建筑的基础埋下了安全隐患的问题。
