Perpendicularity adjusting device for ultralow-position steel pipe pile adopting top-down construction method and correction method thereof

Abstract

The invention discloses a perpendicularity adjusting device for an ultralow-position steel pipe pile adopting a top-down construction method and a correction method of the perpendicularity adjusting device for the ultralow-position steel pipe pile adopting the top-down construction method. The perpendicularity adjusting device for the ultralow-position steel pipe pile adopting the top-down construction method comprises a steel pipe pile original section, a steel pipe pile lengthening section, a steel reinforcement cage and a dip meter. A supporting end face is arranged on the circumferential side of the upper end of the steel pipe pile lengthening section. Two through holes are formed in the supporting end face and are in bilateral symmetry. A perpendicularity adjusting frame is arranged on the circumferential side of a pile hole. The supporting end face is arranged on the perpendicularity adjusting frame. Two perpendicularity adjusting mechanisms are arranged on the perpendicularity adjusting frame. Each perpendicularity adjusting mechanism comprises a pulley, an electric block, a hanging ring arranged at the lower end of the steel pipe pile original section and a steel wire rope,wherein one end of the steel wire rope is fixedly connected with the hanging ring, and the other end of the steel wire rope is downwards wound around the lower portion of a tension sleeve on the steel reinforcement cage, then upwards extends along the outer walls of the steel pipe pile original section and the steel pipe pile lengthening section, extends out from a through hole on the corresponding side, passes by the pulley and then is connected with a hook of the electric block. The perpendicularity adjusting device for the ultralow-position steel pipe pile adopting the top-down construction method effectively solves the perpendicularity correcting problem of the steel pipe pile with the top elevation being excessively low or below 0 meter.

Description

technical field [0001] The invention relates to a vertical adjusting device and a correcting method thereof, in particular to a vertical adjusting device and a correcting method for an ultra-low-position steel pipe pile in an upside-down method. Background technique [0002] The vertical adjustment technology in the prior art mainly includes four vertical adjustment technologies such as the vertical adjustment method of the airbag under the hole, the vertical adjustment method of the mechanism under the hole, the vertical adjustment method of the ground positioning frame, and the vertical adjustment method of the guide sleeve. These four vertical adjustment techniques and equipment have the following defects: 1) the operating conditions are poor, the vertical adjustment device is far away from the ground, and installation and removal are difficult; 3) There are certain requirements for the top elevation of steel columns or steel column piles, generally 0.5 meters above the g...
