Abstract

The invention discloses a steel pipe column positioning device, and relates to the technical field of building construction device.The steel pipe column positioning device comprises a base, a full-slewing drilling machine and a drilling rod, the full-slewing drilling machine and the drilling rod are arranged on the base, a through hole allowing the drilling rod to penetrate is formed in the base, supporting legs are arranged at the four corners of the base, a connecting plate is slidably arranged on the supporting legs, and a supporting air cylinder is arranged on the connecting plate; a piston rod of the supporting air cylinder penetrates through the connecting plate to be connected with the supporting leg, a transmission gear is arranged on one side of the connecting plate, a static tooth-shaped rod meshed with the transmission gear is arranged on the supporting leg, and a movable tooth-shaped rod meshed with the transmission gear is arranged on the base. The distance between the connecting plate and the supporting legs and the distance between the connecting plate and the base are increased or decreased through the supporting air cylinders at the same time, so that upward stable lifting of the full-slewing drilling machine and the drilling rod is achieved, collision of the drilling rod to a steel pipe column is effectively reduced, and then the perpendicularity of the steel pipe column is ensured.

Description

technical field [0001] The present application relates to the technical field of building construction devices, in particular to a steel pipe column positioning device and a construction method thereof. Background technique [0002] At present, ground pile construction usually uses a full-rotary drilling rig for drilling. The full-rotary drilling rig is driven by a power unit to rotate the rotary device of the drilling rig, thereby driving the drill rod with the drill bit to rotate. The drill rod is hollow and the soil is cut by the drill bit. [0003] The power unit drives the drill pipe to rotate, and the hydraulic device on the full-turn drilling rig provides a downward vertical force to press the drill pipe into the ground to form a guard arm. The soil inside the drill pipe is taken out through the peripheral equipment room, and the steel pipe column below is poured into it. concrete. When the concrete is initially set, the full-rotary drilling rig and the drill pipe ar...
