Basis and pier stud construction；
5#, 6#, 7# pier capping beam holder are set up, the construction of 5#, 6#, 7# pier capping beam waits for that concrete bullet mould and intensity reach design After value, tensioning bent cap prestressed strand；
S2：Main arch is constructed：Arch springing section pre-buried steel Arch rib positioning steel member is installed, reinforcing bar after-pouring arch springing coagulation has been bound Soil；
Construction main arch bracket basis sets up holder, and precompressed, adjustment holder and template；
The segments main arch 1# and the segments subarch 4# are installed on holder, and major arch rib 2#~5# sections are sequentially installed on holder Section and the segments subarch 2#~3#, corresponding connector is welded after arch rib line style is adjusted in each segment steel pipe, stull；
S3：Vault support installation：Closure section steel pipe is installed, adjusts welded still pipe after line style, and carry out arch springing concrete Construction；
Erecting and welding vault supports, and observation mark is carried out on arch rib, and observation is carried out in each stage of construction；
S4：Pier column is installed：The symmetrical lower pipe concrete of pumping waits for that down tube concrete layer intensity, bullet mould reach design value It is symmetrical that upper tube inner concrete is perfused and after age concrete phase is more than four days；
After pipe inner concrete reaches design strength and age concrete phase is more than four days, transverse girder between arch rib is removed, is installed on arch Column and intercostal crossbeam；
Pier column and intercostal crossbeam upper bracket are installed, bridge pier and column upper beam are installed, main arch span centre is subsequently mounted and hangs Bar and span centre suspender crossbeam；
S5：Bridge floor rack construction：From main arch and subarch both ends span centre floorings are symmetrically installed to by upstream and downstream along bridge；
It is symmetrical to pour the contact of bridge panel longitudinal wet and laterally wet contact, with post-stretching suspender force；
S6：Surfacing Construction：Symmetrical construction deck paving appurtenant work replicates suspender force and adjusts to design value, The spray painting application of steel pipe protection face, after the completion of construction, field test is simultaneously checked and accepted.
It preferably,, should be according to design drawing when installing arch springing section pre-buried steel Arch rib positioning steel member in the step S2 Pre- picture mosaic and peg figure are drawn, rod piece number and quantity is checked, spike dowel length areas, lifting center of gravity position is marked on basic rod piece It sets and unit weight and installation direction.
Preferably, in the step S2, holder is contacted with arch rib steel pipe using face, avoids arch rib steel pipe partial from generating excessive Concentrated stress.
Preferably, in the step S3, when vault support is installed, it should ensure that the antidumping in steel girder cantilever erection process is steady Determine coefficient, counterweight balance is carried out with ballast or girder steel dead weight, meets Middle span closing maximum cantilever installation requirements, and spelled on holder When the longeron of the segments steel loading beam 1#, it is necessary to which in the cantilever end of longeron, interim fulcrum is set.
Preferably, in the step S5, during tensioning suspender force, tensioning fulcrum is hung pretensioning span centre sunpender again Bar, sunpender sunpender, span centre both sides and the symmetrical tensioning of bridge floor on the outside of tensioning again on the inside of pretensioning.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is applied in strict accordance with arrangement and method for construction and construction detailed rules and regulations Work, it can be ensured that stress and deformation in arch erection are controlled, and are ensured in arch bridge across the high-precision closure of span centre.
