Prefabricated pipe pile and manufacturing process thereof
The invention provides a prefabricated pipe pile and a manufacturing process, the prefabricated pipe pile comprises a common concrete pipe, a reinforcement cage and a steel mold, sleeves are horizontally arranged on the periphery of the surface of the common concrete pipe, and spiral reinforcement arms are welded to the sleeves; a reinforcement cage is bound on the surface of the common concrete pipe, a steel mold is arranged on the outer side of the reinforcement cage, and constructional steel bars are vertically arranged in the common concrete pipe; an ultra-high performance concrete layer is arranged between the reinforcement cage and the steel mould; and a switch valve is arranged on the steel mould wall of the steel mould. According to the manufacturing process of the prefabricated pipe pile, the problem that in existing pipe pile production, an inner film is difficult to demould is solved, the problems that a common pile is low in durability and poor in corrosion resistance in a complex environment are solved through ultra-high performance concrete, meanwhile, a control valve is designed on a steel mould, the UHPC pouring progress is conveniently checked, and excessive air in the steel mould is conveniently discharged.
本发明提供了一种预制管桩及制作工艺，所述预制管桩包括普通混凝土管、钢筋笼和钢膜具，所述普通混凝土管表面的四周水平设有套筒，套筒上焊接螺旋钢筋臂；普通混凝土管表面绑扎钢筋笼，钢筋笼的外侧设有钢膜具，普通混凝土管内部竖直设有构造钢筋；钢筋笼和钢膜具之间为超高性能混凝土层；钢膜具的钢模具壁上安装有开关阀门。本发明的预制管桩制作工艺解决了现有管桩生产中内膜难以脱模的问题，使用的超高性能混凝土解决了在复杂环境中普通桩耐久性低，抗腐蚀性能差的问题，同时在钢模具上设计了一种控制阀，便于检查UHPC浇筑进度，排出钢膜具内多余空气。
