Static drill rooted pile lifting and threading device and construction method thereof
The invention relates to a static drill rooted pile lifting and threading device. The device comprises a self-balancing lifting tool for lifting a pipe pile and a lifting rope hook assembly; the lifting rope hook assembly is mounted on the self-balancing lifting tool and comprises a first pulley, a hanging rope arranged on the first pulley and a pendant connected to the lowermost end of the hanging rope; the first pulley is connected with a first driving mechanism and can be wound around the first pulley under the action of the first driving mechanism to ascend or descend; and the pendant penetrates through a middle hole channel of a lifted tubular pile. When the device is used, an upper pile section is lifted, the pendant penetrates through the middle hole channel of the upper pile section and the bottom of the upper pile section, then the pendant is connected with a prestressed wire at the top of a lower pile section buried underground, and the first pulley performs winding to drivethe prestressed wire at the lower part to move upwards and penetrate through a hole of the upper pile section. Compared with the prior art, the device can solve the problem that a wire in a pile holeof the lower pile section can hardly penetrate through a hole of the upper pile section, and the construction process is greatly accelerated.
本发明涉及一种静钻根植桩吊装穿线装置，包括：自平衡吊具，用于吊装管桩；吊绳挂钩组件，安装在所述自平衡吊具上，包括：第一滑轮、设置在所述第一滑轮上的挂绳以及连接在所述挂绳最下端的坠件；所述第一滑轮连接第一驱动机构，并在所述第一驱动机构的作用下能够绕所述第一滑轮收卷，进行上升或下降；所述坠件穿过吊装的管桩的中间孔道。使用时，起吊上节桩，坠件从上节桩穿过其中间孔道，穿过上节桩底部后，坠件与已埋入地下的下节桩顶部的预应力导线连接，收卷第一滑轮，带动下部的预应力导线上移并穿过上节桩的孔洞。与现有技术相比，通过本发明装置能够解决下节桩桩洞内的导线难以穿过上节桩洞内的问题，大大提高施工进程。
