To solve the above problems, such a ultra-deep of proposed adoption is inverse to make steel pipe column verticality control device, including steel pipe column
Locating steel frame, top hydraulic correction device and lower hydraulic means for correcting, the positioning of steel pipe column locating steel frame are set to the upper of foundation pit
At end, steel pipe column vertically passes through steel pipe column locating steel frame and extends in foundation pit, axis of the top hydraulic correction device along steel pipe column
It is arranged to distribution, and the base end of top hydraulic correction device is fixed on steel pipe column locating steel frame, top hydraulic correction device
Hydraulically extensible end hold out against to the side wall of steel pipe column, the lower hydraulic means for correcting is circumferentially distributed to be fixed on steel pipe column
The base end of lower end, lower hydraulic means for correcting is fixed on the side wall of steel pipe column, the hydraulically extensible of lower hydraulic means for correcting
End is vertically and fixedly provided with proofreading board.
In forenamed vertical degree control device, the top hydraulic correction device and lower hydraulic means for correcting are along level side
To setting；
In forenamed vertical degree control device, shared two groups up and down of the top hydraulic correction device, and upper and lower two groups of top
Hydraulic correction device is vertically arranged in a one-to-one correspondence；
Its application method is as follows:
During steel pipe column decentralization, top hydraulic correction device makes the center pair of steel pipe column by telescopic device adjustment
Quasi- foundation pit central point, standard cylinder barrel mold check center position and verticality, and external manual measurement ensures that rack contraposition is accurate
After take out mold；
After decentralization in place, promotion 20mm slightly keeps steel pipe column hanging, carries out measuring for verticality at this time, according to testing result
Telescopic device drilling depth in lower hydraulic means for correcting is adjusted, corrected to make steel pipe column bottom centre point and foundation pit center
Point is overlapped, and guarantees steel pipe column verticality.
Compared with prior art, the invention avoids steel pipe column run-off the straight in the construction process, cause subsequently to connect down
There are quality problems in continuous wall, influences contrary sequence method underground construction quality.This method is easy to operate, and materials are convenient, sound construction, safety
Property it is high, overcome the deficiencies in the prior art.
Detailed description of the invention
Fig. 1 is the structural schematic diagram under use state of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention will be made below further detailed
Explanation.
