Drill pile pulling-out tool
The invention provides a drill pile pulling-out tool. The drill pile pulling-out tool comprises a base and a C-shaped wrench arranged above the base, wherein the base and the C-shaped wrench are connected through a vertical rod; the head of the C-shaped wrench is in pin joint with a handle rod; and the top end of the vertical rod is in pin joint with the handle rod. According to the drill pile pulling-out tool, the handle rod and the head of the C-shaped wrench are movably connected in a using state, instantaneous upward and relatively strong friction force is repeatedly formed on a drill pile in a wrench opening of the head in the repeated tilting and falling process of the front end of the handle rod, and the drill pile is driven to continuously move upwards until the drill pile is pulled out. The drill pile pulling-out tool can be used for quickly and efficiently pulling out pile foundation components such as a ground wire pile under the condition that only one person is needed for operation, so that a series of problems such as many participants, low efficiency and high possibility of safety accidents caused by adopting other existing modes are avoided.
本发明提供了一种钎桩起出工具，包括底座及其上方的C型扳手，二者通过垂直的竖杆连接；C型扳手的头部和柄杆销接，竖杆顶端和所述柄杆销接。本发明在使用状态下通过C型扳手柄杆和头部的活动连接，在柄杆前端的反复翘起、回落过程中对头部扳口内的钎桩反复形成瞬时向上的、较强的摩擦力，带动钎桩不断上移直至被起出。本发明可在仅需一人操作的情况下可快速、高效地起出地线桩等桩基构件，避免了采用其它现有方式所导致的参与人员多、效率低以及易发生安全事故等一系列问题。
