Description
Technical field
The present invention relates to a kind of steel truss girder continuously pushes up system, belong to bridge foundation construction technical field, more particularly to it is a kind of
Thrustor can follow the node self-adapting successively incremeantal launching method system that steel truss girder connection is moved together.
Background technology
Incremental launching method is the important construction technology of modern bridge construction.With the application extensive and bridge further of steel truss bridge
The continuous innovation of girder construction process, the incremental launching construction mode of steel truss structural bridge are arisen at the historic moment, so as to the adaptive of pushing tow system
The higher requirements of Ying Xingyou.Traditional pushing tow system is typically only applicable to continuous box girder, it is impossible to meet steel truss girder Node distribution
Discontinuously, and node location with work progress be continually changing the characteristics of.
The overall continuous top of many internode bridge steel beams is disclosed in Chinese utility model patent description CN202644409U
Push away hydraulic system, its category engineering construction hydraulic pressure facility field, 4 groups of two sets identical oil pumps respectively by Motor drive, respectively by right
Two load-sensitive proportioning valves of forward and backward jack are answered to provide pressure oil for the forward and backward jack of continuous jack assembly；Gear
Oil pump receives Motor drive, forward and backward solenoid directional control valve delivery pressure respectively corresponding with the anchorage steel strand wires system of forward and backward jack
Power oil, the clamping or release of the forward and backward jack anchorage steel strand wires system of correspondence control；Sensor is very heavy before and after being separately positioned on
Top, the key position control point of the forward and backward jack correlation displacement section of correspondence are set with control signal, and control point signal feeds back to
The solenoid directional control valve of the load-sensitive proportioning valve and control anchorage steel strand wires system of control jack action, each valve make sound respectively
Should, the successively incremeantal launching method operation of incremental launching construction by multipoint jacking control, synchronous shift is realized, although there is the utility model multiple spot to push up simultaneously
Push away, Synchronization Control accurately advantage, but the utility model can not meet steel truss girder Node distribution it is discontinuous when incremental launching construction,
And the utility model complex structure, when need remote large span realize steel truss girder incremental launching construction when, certainly will cause to apply
The increase of work cost and the reduction of efficiency of construction.
A kind of walking type multi-point jacking-pushing construction method is disclosed in Chinese invention patent description CN102587281A, its
Solve the problems, such as girder safety moving in the engineering constructions such as bridge, grade separation, quick in place, it is characterized in that being provided with collection jacking,
Translation, thrustor in one is laterally adjusted, the suitable bridge of steel box-girder is completed to, direction across bridge, movement vertical up and down or adjustment；
Using two steps pushed up, push away alternately, integral steel box corbel is risen, further along delivery；Afterwards steel box-girder is placed in temporarily
On pier structure, a pushing tow process is completed, then by the pipe bending cylinder contracting cylinder bottom portion in thrustor, carry out next pushing tow work
Industry, is circulated with this；Although the method have jacking, pushing tow, reduction, return step, safety and steady, the advantages of easy to operate,
Be that the method needs multiple Temporary Piers to be arranged so as to complete the pushing tow of overall steel box beam according to thrustor, which adds and apply
The cost of work and time-consuming, simultaneously for node location steel truss girder mechanism pockety, as the Temporary Piers in the method are
It is irremovable, because the method can not meet the incremental launching construction of multistage node steel truss girder pockety.
A kind of porous large-span continuous steel truss girder multiple spot is disclosed in Chinese invention patent description CN101831874B
Synchronous push construction method, which comprises the following steps：(1) assembled steel truss girder assembly platform and pushing slide at the bridge pier of bank；
(2) an assembled section steel truss girder and nose girder on steel truss girder assembly platform；(3) vertical jack pair steel truss girder is set and is supported and turn
Change, then successively incremeantal launching method jack, steel strand wires, liquid electrical integrated control system are installed；(4) operate liquid electrical integrated control system
Pushing tow operation is carried out to steel truss girder；(5), after the above-mentioned section steel truss girder pushing tow end of job, continue to spell on steel truss girder assembly platform
Steel loading trusses, carries out pushing tow operation next time, and repeat the above steps cycle operation completes porous m longspan steel truss girder pushing tow and applies
Work.Although the invention realizes the thrusting action of longspan steel truss girder, while having short time limit, construction safety, quality guaranteed
The advantages of, but the invention needed designed in advance and laying steel truss girder assembly platform before pushing tow steel truss girder, can so increase
The construction cost of steel truss girder pushing tow, increases the man power and material spent by pushing tow, and the invention is by controlling multiple bridge piers
On pushing tow jack complete pushing tow, thus cannot realize that thrustor changes with the node location one of steel truss girder.
