Problems solved by technology

[0005] For the above-mentioned defects that exist in the prior art, the problem to be solved in the present invention is to solve the uneven settlement and inclination deformation of the frame frame / column in the substation and other industrial and civil engineering, especially when the ground subsidence is unstable and the frame frame / column Make the frame or column work safely and stably under normal production operation

Embodiment 1

[0053] Please combine figure 1 with figure 2 Let's understand the basic deviation correction or lifting adjustment method of Embodiment 1 of the present invention. Such as figure 1As shown, the foundation involved in the present invention includes one or more foundation piers 1 (only one foundation piers are shown in the figure), and the foundation piers 1 are supported with structural supports or columns 2 . figure 1 The foundation pier 1 in the figure is not tilted, but it may be tilted due to uneven settlement of the foundation in practice. This embodiment takes the situation when it does not tilt as an example for illustration.

[0054] The basic deviation correction or lifting adjustment method of the present invention comprises the following steps:

[0055] Step 1: Excavating around the foundation pier 1 to form a foundation pit for construction. Or excavate around the entire foundation to form a foundation pit that is convenient for construction.

[0056] Step 2, ...

Embodiment 2

[0068] Such as image 3 with Figure 4 As shown, compared with Embodiment 1, in Embodiment 2, the first platform beam 32 is used to replace the platform pier 3 in Embodiment 1, wherein the first platform beam 32 is a strip beam, and the two strip beams 32 relatively parallel settings. Obviously, the scheme of using beams instead of piers is completely feasible, but the scheme of using beams requires a large amount of construction, but using beams instead of piers has a larger foundation area and heavier weight, which can improve its stability.

Embodiment 3

[0070] Such as Figure 5 As shown, the difference between the third embodiment and the second embodiment is that the first adjusting beam 40 is used to replace the adjusting pier 4 in the second embodiment. The effects of the two are similar, except that the amount of construction increases, but the structural strength of the first adjusting beam 40 is greater than that of the adjusting pier 4, so as to drive the pier 1 up and down.

Abstract

The invention discloses a foundation correcting or lifting adjusting method. A foundation pit for construction is dug in the periphery of a foundation pier or a foundation; the foundation pier is cleaned, and chiseling is conducted on the local surface of the side face of the foundation pier; the foundation pier is divided into an adjusting table and a base table along a horizontal face; reinforcing steel bars are implanted into the side face of the foundation pier, and a plurality of sets of adjusting piers connected with the adjusting table and a plurality of sets of bearing table piers connected with the base table are manufactured; lifting locking devices are installed on the sets of adjusting piers and the sets of bearing table piers respectively; the foundation pier is divided into the adjusting table and the base table along the reference horizontal face; and the lifting locking devices are operated so that the adjusting piers can drive the adjusting table to move vertically, and the posture of a constructed support or a stand column supported on the foundation pier can be adjusted to be in a perpendicular state and a designed height. Furthermore, a first ring beam or two bar-shaped beams can be adopted to be additionally arranged to the outer side of the foundation pier to replace the adjusting piers or the bearing table piers. According to the foundation correcting or lifting adjusting method, multi-angle correcting or lifting adjusting can be conducted on the sinking foundation so that the constructed support or the stand column on the foundation can keep the perpendicular state, and the foundation can be adjusted continuously.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a foundation deviation correction or lifting adjustment method, which adjusts the posture of a frame support or a column above the foundation so that it is in a vertical posture and a designed height. Background technique [0002] Some substations have uneven settlement and tilt deformation of some structural supports, which affect the safe operation of structural supports, busbars, incoming and outgoing interval conductors, indoor busbars and power grids. The reason is that the foundation has a certain degree of uneven settlement, ground hollowing, subsidence, etc., and some ground settlement is ongoing and not yet stable; it affects the safe and stable operation of the substation. For this reason, it is necessary to carry out transformation and treatment of structural supports, columns, etc., to eliminate direct hidden dangers that may affect safe production an...
