Hollow prefabricated concrete pile and machining method thereof
The invention relates to a hollow prefabricated concrete pile and a machining method thereof. The concrete pile comprises a pile body, a plurality of main ribs and a core pipe; the plurality of main ribs are arranged and bound into a reinforcement cage through spiral ribs; the distance between the main ribs and the outer surface of the pile body is 0-10mm larger than that of the existing standard; the main ribs are provided with pier heads and limited through end plates; the core pipe is connected with the reinforcement cage and then fixed to the center of the pile body; the core pipe is a hollow round pipe or a hollow square pipe; the two ends of the core pipe are closed; and the pile body is provided with a cavity with the section being round or square due to the core pipe. The machining method comprises the steps of concrete preparing, reinforcement cage manufacturing, core pipe installing, tensioning, pouring, steam curing and demolding. Compared with a hollow pile, the hollow prefabricated concrete pile can be used for corrosive geology, and the impact resistance of the end of the pile is improved during pile sinking; and compared with a solid pile, the usage amount of concrete is reduced, the weight of the concrete pile is reduced, cost is saved, transportation and construction are convenient, and meanwhile the difficulty of the manufacturing method is lowered.
本发明涉及一种空心预制混凝土桩及其加工方法，混凝土桩包括桩身、主筋、芯管。主筋有多根，主筋通过螺旋筋绑扎为钢筋笼，主筋与桩身外表面距离比现有标准远0—10mm，所述主筋设置有墩头且通过端板限位。芯管与所述钢筋笼连接后固定于桩身中心，芯管为中空的圆管或方管，芯管两端封闭，桩身因芯管存在截面为圆形或方形的空腔。加工方法包括配制混凝土、钢筋笼制作、芯管安装、张拉、浇筑、蒸养、脱模。本发明相比较空心桩可用于腐蚀性地质，在沉桩时提高桩端部抗击打性，相比较实心桩减少了混凝土的用量，减轻混凝土桩重量，节省成本，便于运输和施工，同时制作方法难度降低。
