Bridge pile foundation pile head breaking protection pretreatment method and device
The invention provides a bridge pile foundation pile head breaking protection pretreatment method. The bridge pile foundation pile head breaking protection pretreatment method comprises the followingsteps that a mechanical iris is arranged on a pile foundation pile head in a sleeve mode, fan blade blades are aligned with a ring tangent line, a steering gear rotate and enables the fan blade bladesto abut against the ring tangent line, a foundation clamp is adjusted and enables a level bubble to be located in the center, and the mechanical iris is leveled so far, the contact portions of the fan blade blades and a pile body are cut through a cutting machine, and after cutting, the steering gear is rotated to enable the fan blade blades to be embedded into an ring cutting seam, and then manual breaking is conducted; the invention further provides a bridge pile foundation pile head breaking protection pretreatment device which comprises the mechanical iris, the lower portion of the mechanical iris is coaxially connected with a pile casing hoop, a set of foundation stand columns are arranged on the periphery of the mechanical iris in the circumferential direction, and the pile casing hoop is movably installed on the foundation stand columns through height-adjustable parts. According to the method and the device, the problem of damage to an effective pile head during traditional pile breaking is solved, and after ring cutting, the effective part and the ring cutting surface of the pile head can be protected by using the method and the device.
本发明提供了一种桥梁桩基桩头破除保护预处理方法，将机械虹膜套入桩基桩头上，然后将扇叶刀片对正环切线处，转动转向齿轮使扇叶刀片抵至环切线，调节基础卡箍使水准泡位于中心，至此机械虹膜调平，扇叶刀片与桩身接触部位通过切割机进行切割，切割之后，转动转向齿轮使扇叶刀片镶嵌至环切缝内；进而进行人工破除。本发明同时提供了一种桥梁桩基桩头破除保护预处理装置，包括机械虹膜，机械虹膜的下部同轴连接有护筒抱箍，机械虹膜的周围周向设有一组基础立柱，护筒抱箍通过高度可调部件活动地安装于基础立柱上。本发明解决了在传统破桩时对有效桩头的破坏的问题，环切之后，能够利用本方法和装置对桩头有效部分与环切面进行保护。
