Static drill rooted pile lifting and threading device and construction method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of pile foundations, in particular to a static drilling and rooting pile hoisting and threading device and a construction method thereof. Background technique [0002] In the construction process of static drilling and rooting pile test piles, it is often necessary to pre-embed stress wires inside the pipe piles. Since a single pile is generally welded and assembled by two or more sections of pipe piles, during the hoisting process, due to the stress wire being set in the bottom pile hole, and then welded to the upper section pile in a vertical state, there is a problem that the pile installed at the lower section How the conductor in the pile hole passes through the difficult problem in the pile hole of the upper section, this seriously hinders the construction process of the pile test pile through drilling and rooting, and reduces the production effect. Contents of the invention [0003] The object of t...
