Instrument.
Background technology
Bridges in Our Country cause high speed development, wherein Deck Steel Pipe Concrete Arch Bridges by its good stress performance, compared with
For easily work progress, there are the series of advantages such as linear of larger across footpath and beauty, occupy in bridge construction important
Status.In recent years, the quantity that domestic Deck Steel Pipe Concrete Arch Bridges are built is more and more, and across footpath is increasing.With arch
The increase of spanning diameter, the height of spandrel column also increase therewith.
The installation of Deck Steel Pipe Concrete Arch Bridges spandrel column is one of Arch Bridge Construction controlling process, column installation pair
Precision it is more demanding, column installation mainly controls its elevation and vertical degree.However, the installation of column can lead to the linear production of main arch
Changing, at the same main arch it is linear variation column installation will have an impact.If for column all using vertically-mounted, column is complete
Portion is after installation is complete, since the linear variation of main arch can cause part column to be no longer on vertical state, and can be around column
Suspension column is deviated to arch bridge span centre direction, and column top deviant is maximum.The offset of column can cause bent cap difficult to install, and oppose
Column stress has an adverse effect.
Therefore, in column installation process, column is gone out by finite element simulation calculation, the influence linear to main arch is installed,
And the influence that the linear variation column of main arch is spent vertically, so as to be pre-set in column installation process and column offset direction
Opposite pre- bias, all columns can be in vertical state after all installation is complete to reach column.Column was installed
Pre- bias control in journey is particularly important.
Existing column control method is mainly the control that column is spent vertically, such as laser vertical degree instrument, this kind of method pair
The control that column is spent vertically has certain effect, but to needing to carry out pre- inclined column not controlling.It can using guiding ruler
Control verticality of stand column, but equally can not the pre- bias of column controlled, and be affected by the technical merit of operating personnel.
The pre- bias of column can be controlled using total powerstation, but Deck Steel Pipe Concrete Arch Bridges are built in mountain area valley more, certain
The erection of total powerstation is difficult under orographic condition, and column installation control belongs to dynamic control, and controlling cycle is long, while needs continuous
