Background
With the leap-type development of urban construction, large-scale high-rise buildings appear. The foundation of the high-rise building faces the problem of deep foundation pit engineering in the construction process. The deep foundation pit construction method comprises a reverse construction method, and the reverse construction method is generally used under special conditions of deep foundation, complex geology, high underground water level and the like. The reverse construction method usually comprises the steps of firstly constructing the peripheral continuous wall and the internal support columns of the basement to form a reverse vertical bearing system. The supporting columns are usually steel columns, and are generally designed in a column-pile form during construction. When one-column-one-pile construction is carried out, pile holes are dug underground in advance, and concrete is used for filling the pile holes after the embedded steel columns are hung into the pile holes. One column and one pile mainly play a role in supporting an upper main body structure and construction load, so that the column and the pile are used as a main stress structure, the embedded steel column needs to be positioned and adjusted to be vertical when being constructed, and the positioning and the vertical degree are strictly controlled.
For example, chinese patent publication No. CN203361660U discloses a device for adjusting and fixing a steel column by a top-down method, which includes a fixing frame, a jack and a screw adjusting rod for adjusting the verticality of the steel column. The fixed frame comprises an underframe and an upper frame arranged above the underframe. Mounting holes are formed in the middle of the bottom frame and the middle of the upper frame, the steel stand columns are inserted into the mounting holes, and the bottom frame supports the steel stand columns; the jack and the spiral adjusting rod are arranged in the peripheral direction of the steel upright post and are abutted against the steel upright post and the upper frame or the lower frame to push the steel upright post to move in all directions to adjust the verticality. However, the device has the following defects in use: the multiple jacks and the spiral adjusting rods are mounted on the upper frame and the lower frame of the device and need to be manually adjusted, and due to the fact that perpendicularity adjustment is a repeated adjustment process, constructors need to repeatedly adjust the multiple jacks and the spiral adjusting rods back and forth on the upper frame and the lower frame respectively, and construction steps are complex.
