Problems solved by technology

[0009] 2) The existing uneven settlement rectification device seldom takes into account the possible overturning risk of the column foot during the deflection correction process, and the safety is low
For example, in the gear lifting and deviation correction device in CN106703091B, relying on a single tooth column for weighing, its pull-out resistance and bending strength are insufficient
In the compression spring lifting device in CN106760903A, during the release process o

Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0052] An embodiment of the present invention discloses an uneven settlement adjustment device for iron tower column feet and an underpinning and lifting method. The structure diagram of the existing iron tower column foot underpinning and lifting device system involved in this embodiment is as follows figure 1 As shown, it mainly includes: basic part 1, fixing system 2, lifting system 3, safety protection system 4. When uneven subsidence occurs at the base of the iron tower, and when underpinning and lifting operations need to be carried out, a safety protection system 4 must first be installed to ensure the absolute s...

Abstract

The invention discloses a differential settlement adjusting device of column feet of an iron tower and an underpinning lifting construction method. The differential settlement adjusting device of the column feet of the iron tower is characterized in that the column feet of the iron tower comprises a lower supporting stand column, and the adjusting device comprises a fixed stand column, a fixed column foot flange, a plurality of adjusting cushion blocks and a plurality of telescopic oil cylinders, wherein a plurality of evenly-distributed fixed anchor bolts are fixedly connected to the inner part of the fixed stand column. According to the differential settlement adjusting device of the column feet of the iron tower, after differential settlement of the column feet of the iron tower occurs, the column feet of the iron tower can be rapidly lifted and adjusted, so that the multiple column feet of the iron tower are always in the same horizontal plane, and the structure is kept stable; the differential settlement adjusting device of the column feet of the iron tower has pressure-bearing and anti-pulling functions, can provide large jacking force and can bear large anti-pulling force in the lifting process of the column feet; after the column feet are adjusted to the set height, fixing is convenient, and long-term efficient operation is kept; the differential settlement of a high and large iron tower foundation in an area with large wind power can be effectively adjusted, and the differential settlement can be repeatedly adjusted according to the settlement condition.

Description

technical field [0001] The invention belongs to the technical field of iron tower column foot and foundation transformation, and in particular relates to an iron tower column foot uneven settlement adjustment device and an underpinning lifting method. Background technique [0002] Existing signal or power transmission tower structures generally have four tower feet, and mostly adopt the load-bearing form of stepped independent foundations and columns, with good strength, rigidity and stability. However, in recent years, with the increasing breadth and depth of underground space development, the foundation of the existing iron tower will settle under the surrounding disturbance, and the footings of multiple iron towers will show uneven settlement, which will lead to the structural internal force and deformation of the upper iron tower increase, affecting safe use. [0003] When the iron tower settles unevenly, it is necessary to adjust its foundation or column foot to restor...
