Bridge pier.Lifting system is constructed using the structure of itself of building bridge, it is more effortless, efficient.
Further, the short sliding installation system of land-based area large-tonnage steel box beam of the utility model, the lifting system it is auxiliary
It helps on Dun Hedun outer support steel pipe framed bents and is additionally provided with steel box-girder load transfer platform.
Further, the short sliding installation system of land-based area large-tonnage steel box beam of the utility model is with steel box-girder center line
Laterally, the sliding route of the short sliding system be vertical shift-it is traversing-vertical shift again.
Include using the method that the installation system of the utility model is constructed：
Step 1：Set up the short sliding system of steel box-girder and mounting slip the device and operating system, debugging；
Step 2：Steel box-girder is transported to bridge location, on large-tonnage crane barge lifting steel box-girder to short sliding system, traction is
System is connect with steel box-girder, adjusts steel box-girder posture, prepares sliding；
Step 3：Start trailer system, steel box-girder is according to first vertical shift, traversing, vertical shift again route slides onto installation position again
Set lower section；
Step 4：Set up steel box-girder lifting system, equipment etc. is installed in place, debug hoisting frame lifting system, prepare into
Row steel box-girder lifts；
Step 5：Mounting hanger and suspender connection, steel box-girder are promoted to setting height；And it is adjusted to design position, it installs
Bracket is shelved temporarily, cushion block is supported on steel box-girder bottom；
Step 6：Conversion load holder is set up, hoisting frame system is removed, carries out subsequent construction.
The short sliding installation system of land-based area large-tonnage steel box beam of the utility model is located at land-based area position for crossing over Jiang Di
