After compensation of undulation oil cylinder leading block assembling finishes, function test in place, oiling grease lubrication；
Frock is ready to；
（3）Crane span structure tries raising：
The pedestal of the fixed voussoir of navigation for pedestal and crane span structure of the bolt at upper hinge that lock on portal frame is installed；
In place, rigging head is poured into a mould at steel wire rope both ends to wirerope-winding；
With the help of gantry crane, using steel wire rope, pico- raising crane span structure leaves crane span structure and puts 2 centimeters of pier, stops 3 minutes, observation
The working condition of steel wire rope；
Continuation lifting crane span structure, which leaves, puts 20 centimeters of pier, stops 10 minutes, observes the working condition of steel wire rope；
（4）Crane span structure rises and rises to transition point：
Such as without exception, raising crane span structure to mid-transition point；
It is put into high support and spot welding；
The rigging head of that section of steel wire rope after cast interception, and connected in hanging beam steel wire rope；
Prepare raising again；
（5）Crane span structure raising is in place：
The step of repeating examination raising observes the situation of steel wire rope；
Raising crane span structure is inserted into locking bolt to original locking socket position；
Raising puts down locking bolt briquetting afterwards in place, is put into navigation locking voussoir, taps fastening and locked, crane span structure installs
Finish.
Further, 300m steel wire ropes are chosen, diametral strength is identical with the hoist rope that former ship is selected, and is 76mm,
BS=4400KN。
Further, the stage crane span structure between two steps is supported with height, is repeatedly tested a little in implementation process, it is ensured that
Starting substep promotion after the security of raising.
Further, steel wire rope live will intercept, and socket wants cast-in-place.
The advantage of the invention is that：
The present invention is safe to use, saves resource, solves the puzzlement of Large bridge frame integral hoisting difficulty, to large dredger from now on
The construction of crane span structure is worth with important references.
