Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0030] It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order in which they are described, unless specifically identified as an order dependent step. It is also to be understood that additional or alternative steps can be employed.

[0031] Although the terms first, second, third, and the like can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to differentiate one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second", and the like need not be taken to implicitly indicate or imply that a sequence or order of importance of the described elements, components, regions, layers or sections. Thus, elements, components, regions, layers or sections discussed below as first elements, components, regions, layers or sections can be termed as second elements, components, regions, layers or sections without departing from the teachings of the example embodiments.

[0032] For the sake of convenience in description, spatial relative terms can be used herein for the purpose of describing one element or feature's relationship to another element or feature as illustrated in the figures.

The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device is inverted, then a lower surface in one orientation becomes an upper surface in another orientation. Accordingly, the examples "below" and "above" can encompass both orientations of the device. Similarly, when a device is oriented in a landscape mode, then a left side becomes a right side and a right side becomes a left side. The spatially relative terms can be used in this specification to reflect such relative locations and orientations.

[0033] The top-down method is an unconventional construction method, which is generally used in special cases such as deep foundation, complex geology, high groundwater level, etc. The top-down method generally constructs the supporting structure first, and then constructs the building foundation pile and column, and then constructs the beam and slab structure of the ground floor, and then excavates the soil and pours each layer of underground structure layer by layer until the bottom plate is sealed. When the top-down method is used, the foundation pile and column of the underground structure are poured into the pile, and the structure column is in the form of a structure column. Since the "poured pile + structure column" of the top-down method is a permanent support structure of the building, the accuracy of the center line, vertical line, horizontal line and azimuth of the structure column when inserted into the poured pile is relatively high.

[0034] In related technologies, in the structure column installation operation, the splicing of the steel pipe column and the tool column is usually carried out on a special jig, and high-strength bolts are basically used for splicing. Considering the connection between construction cost and construction process, the tool column is generally considered for reuse, at which time the high-strength bolt dismounting problem after the steel pipe column installation is involved.

However, the above operation mode has the following problems:

[0036] (1) Since the concrete pouring in the steel pipe column will be over-poured and the clamping time will be higher than the concrete setting time, the concrete will be set above the bolt hole, at which time the set concrete needs to be cleaned below the bolt hole before the bolt dismounting work can be carried out;

[0037] (2) The entering of the tool column for the bolt dismounting operation is a limited space operation, which has certain safety risks;

[0038] (3) For small diameter steel pipe column installation operation, due to the matching tool column diameter is small, no operation space for bolt disassembly.
