Before girder steel lifting, some obvious measurements are set to carve on the girder steel facade on girder steel both ends and girder steel below each Heave Here
Spend line；
Theodolite is set b,
Theodolite erect-position must is fulfilled for that girder steel lifting process is unobstructed and reflective, and the good sight of Measurement scales line is preset to girder steel
Survey, it is ensured that accurate to the number of degrees of graduation mark；
C, girder steel lifting lifting
In girder steel lifting process, information commander's control hoist engine that department rope commanding provides according to transit survey personnel is lifted
The operating personnel of girder steel, if the girder steel both ends discrepancy in elevation adjusts in time when exceeding prescribed limit value, control girder steel lifting, it is ensured that whole beam
Horizontal lifting；
D, theodolite monitors in real time and the discrepancy in elevation adjusts
In girder steel lifting process, by two theodolites for being arranged at ground to the level measurement scale on the facade of girder steel both ends
Line is observed, if the specific amount of deflection is informed department rope commander people by the graduation mark number of degrees deviation at girder steel both ends more than 5cm, survey crew
Member, department rope commanding command the adjustment of hoist engine operating personnel progress girder steel hoisting depth in time, it is ensured that the girder steel both ends discrepancy in elevation
No more than 5cm, so as to control the overall horizontal lifting of girder steel, steel girder erection is completed.
The steel beam lifting method of two theodolite Synchronization Control girder steel both ends discrepancy in elevation of the present invention can also use following
Technical measures are further realized.
Foregoing method, wherein each Measurement scales line has unified setting specification.
After adopting the above technical scheme, the steel beam lifting side of the two theodolite Synchronization Control girder steel both ends discrepancy in elevation of the present invention
Method has advantages below：
1st, steel beam lifting apparatus structure is simple, easy to use；
2nd, the overall horizontal lifting lifting of stability contorting girder steel, controlling are good；
3rd, considerable economic cost is saved, reduces steel beam lifting engineering cost.
