Self-balancing static drill rooted pile hoisting and threading device and construction method thereof

Abstract

The invention relates to a self-balancing static drill rooted pile hoisting and threading device which comprises a self-balancing hoisting device and a lifting rope hook mechanism. The self-balancinghoisting device comprises a base and a supporting column, a hoisting bracket is arranged at the upper end of the supporting column, a hoisting pulley block is arranged on the hoisting bracket, a hoisting inhaul cable is wound on the hoisting pulley block, and a first driving mechanism used for winding the hoisting inhaul cable is arranged on the base; the supporting column is provided with a plurality of sensors used for detecting whether a tubular pile is parallel to the supporting column or not; the lifting rope hook mechanism is installed on the lifting bracket and comprises a lifting ropepulley, a hanging rope arranged on the lifting rope pulley and a pendant connected to the lowermost end of the hanging rope, and the lifting rope pulley is connected with the second driving mechanismand can be wound around the lifting rope pulley under the action of the second driving mechanism to ascend or descend; and the pendant penetrates through a middle hole channel of the hoisted tubular pile. Compared with the prior art, the self-balancing static drill rooted pile hoisting and threading device can solve the problem that a wire in a pile hole of the lower pile section is difficult to penetrate through a pile hole of the upper pile section, and meanwhile the perpendicularity of pile planting can be kept.

Description

technical field [0001] The invention relates to the technical field of pile foundations, in particular to a self-balancing static drilling and rooting pile hoisting and threading device and a construction method thereof. Background technique [0002] During construction, static drilling and rooting piles generally need to be equipped with multiple sections according to the depth, and adjacent static drilling and rooting piles need to be assembled and spliced ​​(such as welding), and verticality control is very critical when connecting multiple static drilling and rooting piles. It is often difficult to control the key points. In addition, during the construction process of static drilling and rooting test piles, it is also 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 placed in the bottom pile hole, when it is we...

AI Technical Summary

Problems solved by technology

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 arranged in the bottom pile hole, when it is welded with the upper section pile in a vertical state, there will be a problem that it is installed in the lower section. How does the wire in the pile hole pass through the pile hole in the previous section?
