2. a kind of method of steel pipe arch bridge suspender replacement, it is to use to be used for steel pipe truss concrete arch-type bridge described in claim 1
The method that the interim pocket device for hoisting of steel wire rope of suspender replacement realizes steel pipe arch bridge suspender replacement, it is characterised in that：Its replacing options
Include the following steps：
A, steel wire rope interim pocket device for hoisting of the installation for steel pipe truss concrete arch-type bridge suspender replacement：
A1, in tubular arch（1）It is above longitudinally asymmetric that one hood type vault anchoring anti-slip system is installed respectively in former sunpender, each
Hood type vault anchors anti-slip system by 2 antiskid anchor ears（4）, 2 rubber pads（23）, prestretching screw rod（5）, 2 arc-shaped steel casees
（3）And it is located at arc-shaped steel case（3）On antiskid block（2）Composition；Rubber pad（23）It is arranged in antiskid anchor ear（4）With tubular arch
（1）Between, arc-shaped steel case（3）With antiskid anchor ear（4）Pass through solder design, antiskid block（2）With arc-shaped steel case（3）Pass through weld seam
Connection；
Bar lazy halyard is changed in A2, installation --- upper steel wire rope（6）With lower steel wire rope（20）：
A21, steel wire ropes are gone up by two（6）One end bypasses conversion beam I（12）The axis pin I of side（13）Pass through rope clamp I（10）Anchoring,
Two upper steel wire ropes（6）The other end around the upper antiskid block of arch（2）It wears down, further around conversion beam I excessively（12）The pin of the other side
Axis I（13）Pass through rope clamp I（10）Anchoring；
A22, by lower prestress fining twisted steel（14）Upper end sequentially passes through conversion beam II（16）, stretch-draw jack（8）, use tensioning
Hold anchorage（9）Anchoring, lower prestress fining twisted steel（14）Lower end passes through attachment device（15）With fixing end anchorage（22）Anchoring；
A23, by four lower steel wire ropes（20）One end bypasses respectively is located at suspender crossbeam（21）Two attachment devices of side（15）
Pin shaft II（16）Pass through rope clamp II（18）Anchoring, four lower steel wire ropes（20）The other end bypass suspender crossbeam（21）Lower section
Protect backing plate（19）It up wears, is located at suspender crossbeam further around crossing（21）Two attachment devices of the other side（15）Pin shaft II（16）
Pass through rope clamp II（18）Anchoring；Lower steel wire rope（20）Pad protects backing plate（19）Catch suspender crossbeam（21）Lower surface；Rubber pad
（23）It is arranged in antiskid anchor ear（4）With tubular arch（1）Between top surface, arc-shaped steel case（3）With antiskid anchor ear（4）Connected by weld seam
It connects, antiskid block（2）With arc-shaped steel case（3）Pass through solder design；
A3, check steel pipe truss concrete arch-type bridge suspender replacement the interim each component of pocket device for hoisting of steel wire rope connection safety with
And stabilization holds lotus ability：
By driving jack（8）Tensioning lower prestress fining twisted steel（14）Examination tensioning is slowly carried out step by step, checks steel wire rope
The connection safety and stabilization of each component of interim pocket device for hoisting hold lotus ability；
B, it removes former sunpender, complete conversion of the Suo Li systems to the interim pocket device for hoisting of steel wire rope：
When former sunpender is formally removed, former sunpender steel wire, synchronous tensioning lower prestress fining twisted steel step by step are cut off step by step
（14）, realize and convert former suspender force to the interim pocket device for hoisting of steel wire rope, complete Suo Li system transforms；Suo Li is converted step by step
The variation control of process floor elevation after former sunpender cut-out, anchors lower prestress fining twisted steel within ± 5mm（14）, it
After remove former sunpender；
C, new sunpender is installed, complete conversion of the Suo Li systems to new sunpender：
New sunpender is installed to finish, step by step the new sunpender of tensioning, a lower prestress fining twisted steel is put in synchronization step by step（14）, realize steel
The interim pocket device for hoisting Suo Li of cord is converted to new sunpender, completes Suo Li system transforms, and Suo Li transfer processes floor elevation becomes step by step
Change control within ± 5mm, new suspender tension in place after, pass through anchor head nut and anchor new sunpender；
D, hood type anchor is removed, is transferred at next former sunpender；
The interim pocket device for hoisting of steel wire rope is removed, is transferred at next former sunpender；
E, every suspender replacement repeats step A~step D, completes other suspender replacements.
