Formula is connected；Load-bearing rail beam to form one with track girder supporting system using being welded to connect；Sliding rail pressing plate is fixed on and holds
At heavy rail road end face center, sliding rail top mark coca pushes away determination according to truss lower boom absolute altitude is counter；Adopted at sliding rail slope section
Processed with hot bending, it is ensured that rail lower surface is fitted with Load-bearing rail beam upper surface, each sliding rail slope slope over 10 needs consistent.
Further, fourth, fifth step through ground by sliding element specifically, by sliding element bottom setting piston shoes, spelled
Dress form lifting elements, by installation at high altitude formed stabilization sliding element, install hydraulic pressure creep machine, connection slip control system and
Sliding power system.
Further, hydraulic pressure creep machine is started after the 6th step is specifically, sliding element and sliding measure are errorless on inspection,
Through accumulation slippage to rail slope section is slid, with the carrying out of sliding construction, piston shoes are slowly departed from by sliding element, realization is slided
Move the automatic unloading of unit；Piston shoes are removed after the completion of unloading, total powerstation monitor in real time truss deformation values are used in slipping；Press
This mode completes structure integral construction through ten accumulation slippage constructions.
The present invention uses above technical scheme, makes it have following beneficial effect：
Uninstall process security is good：Uninstall process is completed in the construction of structure accumulation slippage, and discharging quantity is with the carrying out of sliding
It is stepped up being completed until unloading, whole uninstall process continuity is good, and power transfer process is continuous, and security is good；
Unloading synchronism is good：For there is the short track unloading situation of multiple slidings, by controlling slope slope over 10 and sliding synchronization
Property, it is capable of achieving the synchronous unloading of structure；
Low cost, progress are fast：Automatic unloading is automatically performed with sliding construction, reduces the throwing of unloading equipment and unloading interim measure
Enter, while saving installation and the dismounting time of unloading interim measure, construction cost is low, efficiency high.
