It is dynamic；
As concrete engineering example, emergency repair gate is arranged in certain flood-relief channel intake tower, and intake tower bulkhead gate groove elevation is
360m~407m.Since bulkhead gate producer is undressed when flood discharging tunnel top surface platform binds, can not be installed before binding,
Therefore it can only lift and install from gate slot at present.Gate widths 8.22m, gate slot left and right banks direction width 8.5m, therefore gate lifts
When can only be lifted by short side, lifting to 407m platform to be turned in upper plenum.
When headstock gear binds, the lifting of later period gate is considered, in each embedded auxiliary suspension centre in rolling open and close machine two sides, carry out
Auxiliary lifts and cooperates rotator construction.
First segment is first lifted by crane, and is temporarily fixed on 407m elevation maintenance door cavity upstream end, second section is hung in recurrence, is set
In in first segment, when using casting concrete pre-buried steel plate suspension centre by first segment and second section when fix.
Third segment is finally lifted by crane, directly enters gate slot after complete overturning in 90 °, is transferred to formulating position, then by second
It is hung on third segment after the swivel of segment, finally first segment is hung in second section, carry out welding and complete whole splicing.
The above embodiment is only the preferred embodiment of the present invention, and protection scope of the present invention is not construed as only limiting
In the concrete form that embodiment is stated, protection scope of the present invention also includes that those skilled in the art conceive institute according to the present invention
It is conceivable that equivalent technologies mean.
