Single-click multi-section pile end hammering pile sinking device, assembling method and construction method
The invention provides a single-click multi-section pile end hammering pile sinking device, an assembling method and a construction method.The pile sinking device is connected into an FRP pipe pile in a penetrating mode, the top of the FRP pipe pile is provided with an opening, the bottom of the FRP pipe pile is blocked by an annular circular plate, the center of the annular circular plate is provided with a through opening, the pile sinking device comprises a force transmission cylinder, and a pile hammer is connected into the force transmission cylinder in a sliding and penetrating mode; the top of the force transmission cylinder is connected with the excitation hammer through an elastic buffering assembly, the bottom end of the excitation hammer presses the top end of the pile hammer in a hammering mode, a pile casing is arranged on the peripheries of the force transmission cylinder, the elastic buffering assembly and the excitation hammer in a hooping mode, a profiling cavity is formed in the pile casing, the excitation hammer is in sliding connection with the inner wall of the profiling cavity, and an annular pipe cavity is reserved between the pile sinking device and the inner circumferential wall of the FRP pipe pile. According to the novel FRP composite pile foundation formed by combining the FRP pipe and the flow-state solidified soil, the problem of interface slippage and debonding of concrete and FRP in the hammering process is avoided, and the problem that concrete in the pipe is difficult to vibrate is avoided by means of the self-flowing characteristic of the flow-state solidified soil.
本发明提供了一种单击多段式桩端锤击沉桩装置、组装方法及施工方法，沉桩装置穿接入FRP管桩内，FRP管桩的顶部具有敞口，FRP管桩的底部封挡环形圆板，环形圆板的中心具有通口，沉桩装置包括传力筒，传力筒内呈滑动穿接桩锤，传力筒顶部通过弹性缓冲组件连接激振锤，激振锤底端锤压桩锤顶端，于传力筒、弹性缓冲组件和激振锤外周呈抱箍设置护筒，护筒内部形成仿形腔，激振锤与仿形腔内壁滑移连接，沉桩装置与FRP管桩的内周壁之间余留环形管腔。本发明使FRP管与流态固化土结合形成的新型FRP复合桩基，避免了混凝土和FRP在锤击中的界面滑移脱粘问题，利用流态固化土的自流特性，避免了在管中混凝土振捣困难的问题。
