(5), according to the assembling method of second section girder, assembled Section of three girder, first segment nose girder, second section nose girder and Section of three nose girder successively;
(6), complete after girder and nose girder assembled, the running motor starting in the electronic running mechanism of rear support leg drives girder, nose girder entirety to advance, the position of nose girder between 0# platform and 1# pier, rear support leg hydraulic system is installed under first segment girder, supporting leg and middle supporting leg hydraulic system in installing on 0# platform, install front leg strut hanging mechanism on front leg strut;
(7), start in supporting leg hydraulic system, by the hydraulic jack in supporting leg hydraulic system in jacking, jack-up girder, then moves front leg strut to 1# pier by front leg strut hanging mechanism, completes installation.
As mentioned above, the described carriage of step () refers to spot welding track.
As mentioned above, the described carriage of step () refers to away driving wheel group.
Carriage is installed, for relatively moving forward and backward of girder, the assembled process of nose girder inside and outside tunnel.
As mentioned above, the described lifting of step (four) is the lifting that adopts automobile to carry out.
As mentioned above, the described interface of step (four) is fixedly to fix with bolt and nut.
As mentioned above, before the described startup rear support leg of step (four) running motor, the crane hook that must not get loose.
As mentioned above, 0# platform and the mortar levelling of 1# pier top carrying application point.Make laying of girder and nose girder more steady.
Compared with prior art, beneficial effect of the present invention:
For bridge fabrication machine manufacturer to bridge fabrication machine in the be connected not enough problem of assembling scheme compliance at tunnel exit place of bridge tunnel, the present invention can carry out in tunnel face the assembled of bridge fabrication machine girder and nose girder, cancel the place between excavation, smooth 0# platform and 1# pier, step into row bridge fabrication machine system at bridge head assembled, do not need place to carry out backfill on a large scale, smooth, sclerosis.Its principle is to utilize the girder of improved bridge fabrication machine to vertically move function, realizes and directly between 0# platform and 1# pier, completes the assembled of bridge fabrication machine.Thereby save a large amount of earth and rock works amounts and greatly shortened installation period.
