Pile head rotary drilling coring device
The invention relates to the field of bridge construction, in particular to an ultra-long pile head rotary drilling coring and pile head breaking device which comprises a rotary drilling rig and a slag salvaging drill bit, a reinforcement cage is arranged in a pile foundation, and the drill bit of the rotary drilling rig directly faces the top of the pile foundation. According to the pile head rotary drilling coring device, the driving assembly drives the rotating shaft and the impeller in the rotating shaft to rotate, the steel impeller rotates to break, drill downwards layer by layer, mix water step by step and continuously break formed concrete to form fragments slightly smaller than the concrete, internal fan blades are closed, and the fragments are extracted out; and the pile head can be conveniently and efficiently broken and removed.
本发明涉及桥梁施工领域，具体的说是一种超长桩头旋挖钻取芯、桩头破除装置，包括旋挖钻机、捞渣钻头，所述桩基的内部设置有钢筋笼，旋挖钻钻头正对桩基顶部。本发明所述的一种桩头旋挖钻取芯装置，通过驱动组件，带动转动轴及转动轴内的叶轮进行旋转，通过钢制叶轮的旋转破除，逐层向下钻进，逐步掺入水，继续破除成型混凝土，形成略小于混凝土碎块，并合拢内部扇叶，提取出来，便于对桩头进行高效的破除。
