A kind of method for construction of being encorbelmented using above-mentioned highway prestress concrete box girder mobile formwork progress concrete box beam, specific steps
For：
Step 1, mobile formwork is assembled, and precompressed is completed；By the adjustable stand column of the rear main support meanss of above-mentioned mobile formwork
It is supported on roadbed or has poured Liang Mianshang, the adjustable stand column of preceding main support meanss is supported at the pier top of the first bridge pier, and adjustment is outer
Rib system so that outer modular system is in place；Colligation bottom plate, web reinforcement, found inner formwork system, colligation roof steel bar, pour；
Step 2, after concrete reaches intensity, tensioning, mobile formwork prepares via；, will after the complete machine via of mobile formwork
Mobile formwork is integrally fallen, and main frame systems are fallen on the vertical shift track of preceding main support meanss and rear main support meanss, is removed
Finish rolling deformed bar；The connector of left bed die and right bed die is removed, the connector of left outside rib and right external fin is removed, then by opening
Anticlockwise oil cylinder and right rotation oil cylinder are by left outside rib and right external fin Unscrew；Gantry crane is run to the rear end of left and right girder；
Step 3, preceding main support meanss are anchored in bridge floor, mobile formwork complete machine vertically moves forward；Front auxiliary strut fills
Put arrival front pier top and supported in pier top；Pay attention to：Need that vertically and horizontally on direction, preceding main support is being filled with chain block before via
Put and anchored with bridge floor；
Step 4, main support meanss anchor with bridge floor after dismounting；Preceding main support meanss pass through support cylinder and rear auxiliary branch
Support arrangement is jacked up the complete machine of mobile formwork by machinery top, and main support meanss are hanging by after；Pay attention to：Complete machine, when jacking up
Main support meanss before first pushing up, then auxiliary support apparatus after pushing up；
Step 5, preceding main support meanss are come to nothing preceding main support meanss by the oil cylinder of itself hooking mechanism, pass through gantry crane
The adjustable stand column of preceding main support meanss is extracted out from beams of concrete and hooks to be forwarded to support up to front pier top and is anchored；Before coming to nothing
The left and right support frame of auxiliary support apparatus；The left and right walking track of auxiliary support apparatus after being laid on bridge floor；Mobile formwork
Complete machine landing, the left lateral walking apparatus and right lateral walking apparatus for making left and right girder and rear auxiliary support apparatus fall in orbit；Note
Meaning：Preceding main support meanss are before the support of front pier top by protection sleeve pipe on the adjustable stand column set of preceding main support meanss；
Step 6, the complete machine of mobile formwork, which moves, causes via in place；By anticlockwise oil cylinder and right rotation oil cylinder by a left side

The bridge construction of combined highway and metro section can be carried out using mobile formwork provided by the invention, can carry out cast-in-place building span ratio
Larger bridge construction, in the installation of the pier of the initial pier of the main bridge of main bridge → first, the left width of pier of the initial pier of main bridge of constructing → the 8th, retreat extremely
The traversing line that turns of the main initial pier of bridge → first pier the right width of pier of the initial pier of main bridge of constructing → the 8th, is torn open to right width in the eight, the 7th Dun Chu
Except the inner formwork system of the present invention and the template and external fin system of outer modular system, main frame systems are retreated to the Dun Chu of initial pier → second
Remove.For external fin system and outer modular system in the present invention using the opening ways of rotation, this mode, which molds, acts few operation letter
It is single, only need one stroke of oil cylinder to reduce labor intensity with folding external mold, mold efficiency high.The complete machine of mobile formwork turns line
Luffing operation need not remove big part.The die sinking mode that mobile formwork complete machine is rotated when the first width is constructed using both ends, fit
Transom pier construction requirement is answered, when the second width is constructed by the way of outside high position rotated inside is traversing, meets double width construction requirement.
Preceding main support meanss, front auxiliary strut device, rear main support meanss and rear auxiliary support apparatus can be installed voluntarily via in place,
The construction of the high pier of high bridge is not only facilitated, also greatly reduces construction cost；Material distributing machine can be set in this equipment, facilitates high pier to apply
Work；Mobile formwork lifting, rotating folding mould, vertical shift via use hydraulic control, stable action, safe and reliable, and greatly
Labor intensity is reduced, while improves efficiency of construction；Supporting leg sets transverse shift oil cylinder, is conveniently adjusted main frame position, just
There is no roadbed and existing beam surface construction across rear end in curve via holes and the traversing line operation satisfaction head that turns；Complete machine uses Integral Lifting
Installation, adapt to high pier construction；Transferred when complete machine is removed using overall, conveniently, safely.
