Embodiment 1

[0039] Example 1: Combining figure 1 Illustrate that the fine vertical adjustment device of one column and one pile of the present invention is used to adjust the verticality of the steel column of the bored pile, and it includes:

[0040] The inner rotating frame 10 is a hollow frame body, and the steel column can penetrate the inner rotating frame 10 and be rigidly connected with it;

[0041] The outer rotating frame 20 is sheathed on the outside of the inner rotating frame 10. The inner rotating frame 10 and the outer rotating frame 20 are arranged coaxially and spaced apart. Rotating frame 20;

[0042] The fixed frame 30 is sleeved on the outer side of the outer rotating frame 20, the fixed frame 30 and the outer rotating frame 20 are coaxial and arranged at intervals, and the outer rotating frame 20 is movably connected to the fixed frame 30 through a pair of outer frame bearings 21 located on its center line. And the axes of the inner frame bearing 11 and the outer fra...

Embodiment 2

[0055] Example 2: Combining figure 1 Describe the fine vertical adjustment system of one column and one pile of the present invention, which includes: a fine vertical adjustment device for one column and one pile installed on the ground at the top of the underground borehole, and a spirit level (not shown in the figure) installed on the steel column, and The spirit level is connected with the control station 70 of the column-by-pillar fine vertical adjustment device for signal connection. After the steel column runs through the inner rotating frame 10 and is fixed by the connecting seat 12, adjust the level adjustment component 1 80 and the level adjustment component 2 90 respectively, so that the center position of the steel column meets the construction requirements, and then tighten the base 40 and the fixing frame by bolts 30. The control station 70 receives the data of the level instrument on the steel column and analyzes and calculates it. By controlling the expansion an...

Embodiment 3

[0056] Embodiment 3: The fine vertical adjustment method of one column and one pile of the present invention, the specific steps are as follows:

[0057] S1: Assemble the one-column-one-pile fine vertical adjustment device as described in Embodiment 1, and the one-column one-pile fine vertical adjustment device is installed above the underground borehole, so that the inner rotating frame 10 is facing the center of the underground borehole, and more The bottom of the first base 40 is connected to the ground, the first hydraulic cylinder 52 and the second hydraulic cylinder 62 communicate with the control station 70 through hydraulic oil pipes, a level is installed on the top of the steel column and hoisted into the underground drill hole, and the top of the steel column passes through the connecting seat 12 and the control station 70. The inner rotating frame 10 is rigidly connected;

[0058] S2: adjust the level adjustment component 1 80 and the level adjustment component 2 90...

Abstract

The invention discloses a one-column-one-pile fine perpendicularity adjustment device, system and method. The problems that the existing perpendicularity adjustment technology is low in centering precision, concrete pouring is inconvenient, and the automation degree is low are targeted. The one-column-one-pile fine perpendicularity adjustment device comprises an inner rotating frame, an outer rotating frame, a fixing frame, a control station, an inner frame perpendicularity adjustment component, an outer frame perpendicularity adjustment component, wherein the inner rotating frame, the outer rotating frame, and the fixing frame are coaxially arranged in a sleeving mode from the inside to the outside, the inner frame perpendicularity adjustment component and the outer frame perpendicularityadjustment component are connected with the control station, the inner rotating frame is movably connected to the outer rotating frame through an inner frame bearing, the outer rotating frame is movably connected to the fixing frame through an outer frame bearing, the inner frame perpendicularity adjustment component is connected with the outer rotating frame and the inner rotating frame, the inner rotating frame is driven to rotate by expansion and contraction of a first hydraulic oil cylinder, the outer frame perpendicularity adjustment component is connected with the outer rotating frame and the fixing frame, the outer rotating frame is driven to rotate by the expansion and contraction of a second hydraulic oil cylinder, the control station receives, analyzes, and calculates level dataon a steel column, and the steel column is indirectly driven to swing in the perpendicular direction by controlling the expansion and contraction quantity of the hydraulic oil cylinders in the innerframe perpendicularity adjustment component and the outer frame perpendicularity adjustment component correspondingly so as to adjust the perpendicularity of the steel column.

Description

technical field [0001] The invention relates to the technical field of civil engineering pile foundation construction, in particular to a fine vertical adjustment device, system and method for one column and one pile. Background technique [0002] The upside-down method construction of underground engineering is an advanced construction technology that can reduce the deformation of the foundation pit, save support costs, shorten the construction period, and has the advantages of energy saving, environmental protection and other green construction. Accuracy must be strictly controlled in order to meet design requirements. [0003] At present, the existing vertical adjustment techniques of steel columns mainly include the following types: the airbag vertical adjustment method 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 casing. All...
