Pile casing striking type rapid pulling-out equipment for pile foundation construction soft foundation
The invention discloses pile casing striking type rapid pulling-out equipment for pile foundation construction of a soft foundation, and belongs to the technical field of highway bridge mechanical equipment. The equipment comprises a protective cylinder body, a supporting assembly, wherein a through hole is formed in the shell in a penetrating manner; a positioning assembly which comprises a positioning ring which is fixedly embedded in the top of the inner cavity of the shell and is provided with an annular groove in the bottom surface; and a knocking assembly which is arranged at the lower half part of the inner cavity of the shell. Before pulling out, the positioning assembly is fixed to the top face of the pile casing, obliquely upward impact force is applied to the fixed clamping plate through a related knocking structure arranged on the annular table, the pressure of equipment on the ground is reduced, acting force is intermittently applied to the equipment, and the attaching acting force of a traditional vertically upward pulling-out pile casing and the inner surface of a foundation pit is reduced. The row-shaped air bags on the two sides are controlled to work in sequence, so that the pile casing is separated from the inner surface of the foundation pit more easily, the pulling force needed for pulling out the pile casing is reduced, the pile casing pulling-out efficiency is improved, and the pile casing pulling-out device can adapt to ground conditions under more conditions.
本发明公开了公路桥梁机械设备技术领域的一种桩基修建软地基用护筒击打式快速拔除设备，包括，护筒本体；支撑组件，所述壳体上开设有贯穿的通孔；定位组件，包括固定嵌设于壳体内腔顶部且底面开设有环形槽的定位环；敲击组件，所述敲击组件设于壳体内腔下半部位置处；本发明在拔除前通过将定位组件固定于护筒顶面，通过环形台上设置的相关敲击结构对定夹板施加斜向上的冲击力，减小设备对地面的压力，对其间歇性施加作用力，降低了传统垂直向上拔除护筒与基坑内表面的贴合作用力，控制两侧的排状气囊依次工作，使得护筒与基坑内表面更容易脱离，进而减小护筒拔除时所需的拉力，提高了护筒拔除的效率，且能够适应更多条件下的地面状况。
