Pushing tow jack type is fluid pressure type punching jack.
In advance pre-buried for termination anchor bar is welded with pre-embedded steel slab and carries out at closure section box beam two ends pre-buried.Will be double
Spell I-steel, cross connecting plate termination lateral stiffening plate, pushing tow termination steel plate and Flat-end plate weld and form steel box-girder, steel
Box beam Welding, on the pre-embedded steel slab of closure section one end, connects the vertical lateral of upper and lower steel box-girder and forms pushing reaction with vertical bridging
Frame.
Jack is placed on Flat-end hold out against pushing tow end plate and pre-embedded steel slab and synchronously apply jacking force and completes pushing tow.
Reaction frame is welded into steel box-girder by Two bors d's oeuveres I-steel, and pre-embedded steel slab and anchor bar are embedded in box beam for one end,
The other end welding pushing tow steel plate and Flat-end plate, jack on surface plate by active force with reaction force acts in closure mouth
Pushing tow is realized on beam-ends box beam pre-embedded steel slab and steel box-girder.
The beneficial effects of the utility model：
1st, by reaction frame piecemeal processing simultaneously welded and installed, reaction frame is installed simply, and overall stressed effect is good.
2nd, reaction frame pushing tow is dismountable after terminating, and achievable material secondary utilizes.
3rd, reaction frame pushing tow jack positioning is simple and effect is good, and pushing tow power transmission is more uniform.
