Description
Technical field
The invention belongs to precast bridge technical field of construction, more particularly to a kind of Bridge Erector for being used to set up full precast beam and
Its bridging method.
Background technology
With the quickening of Chinese Urbanization pace of construction, in order to economize the land resource, urban road, urban light rail and subway
The aerial part overpass such as circuit is more and more.Its with conventional overpass except that, these elevated bridges mostly occur
In surrounding city, execution conditions are complicated, and construction environment traffic pressure is big, and higher requirement is proposed to Bridge Erector adaptability.
Commonly used at this stage highway bridging machine construction technology is ripe and is widely used, but it the shortcomings that with work condition environment
Development be also more obvious：
1st, existing highway bridge pier stud and bent cap typically take the colligation of on-site hoisting reinforcing bar to install, and in-site installation template, cast in situs is supported
The mode of shield, constructs larger by natural environment influence, and quality control difficulties are serious to ambient contamination.
2nd, existing Bridge Erector generally itself can not realize reverse construction, be typically necessary the auxiliary dismounting of large tonnage crane,
Even carrying out the dismounting of complete machine can realize；
3rd, it is many during existing Bridge Erector via traveling to require to lay vertical shift rail in beam face, not only to having built bridge beam stress not
Profit, also influence efficiency of construction；
4th, it is not that wheel track bridge floor traveling is exactly to hang wheeled during each supporting leg via of existing Bridge Erector, former is applied in both modes
Work bridge floor workload is big, and efficiency is low, and influences stress of having built bridge；Latter repeatedly occurs supporting leg during practical application and fallen
Fall or traveling be not smooth, caused by loss it is very big.
It is more and more urgent to be consequently for overhead highway, urban light rail, the Bridge Erector demand of subway overpass.
