Description
Technical field
The present invention relates to science of bridge building field, and steel reinforced concrete combination permanent bridge is transform as in particular to a kind of Bailey beam make-shift bridge
Construction method.
Background technology
In high-speed railway bridge construction, the matter transportation and equipment of engineering construction, which are marched into the arena, to be needed to build along the railway greatly
The interim sidewalk of engineering construction is measured, when sidewalk is by barriers such as cheuch or rivers, usually builds the leap of some make-shift bridges.It is military
Bailey beam make-shift bridge has the characteristics that technology maturation, easy for construction, cost is low, enjoys the favor of construction engineering units.But by
It is steel construction in Bailey beam, is easy to corrode, poor durability, more as temporary structure, after the completion of engineering construction, fraction is just temporarily
Emergency management and rescue passage of the road as railway, will largely be removed.
However, local government then wishes that interim sidewalk during high-speed railway construction can continue as the supplement of local road network
Play a role, this requires make-shift bridge on interim sidewalk becoming permanent bridge.Railway is distributed in because make-shift bridge is scattered
Along the line, it is under the jurisdiction of different railway construction construction bid sections and local government, make-shift bridge is removed into again original position and builds permanent bridge
Scheme it is then high and need to suspend traffic without by local government being received for a long time by building cost.
The content of the invention
In view of this, the invention provides the construction party that a kind of Bailey beam make-shift bridge transform steel reinforced concrete combination permanent bridge as
Method, this method, will using the method in original make-shift bridge external wrapping concrete after the completion of High speed railway project major project
Existing Bailey beam make-shift bridge transformation and upgrade are permanent bridge, become dismounting and are redeveloped into upgrading strengthening reconstruction, meet to supplement local road
Net is actually needed.
To achieve the above object, the present invention is achieved through the following technical solutions：A kind of Bailey beam make-shift bridge transform steel as
The construction method of mixed combination permanent bridge, comprises the following steps：
(1) foundation construction, foundation pile is set up respectively along the both sides that bridge moves towards in Bailey beam make-shift bridge original base stake, and
Apron piece is poured at the top of foundation pile, the original steel pipe column bridge pier of Bailey beam make-shift bridge is supported using apron piece；
(2) Bridge Pier Construction, bridge pier formwork for placing is installed in make-shift bridge original steel pipe column bridge pier outer rim, in steel pipe column
Outside casting concrete, concrete filled steel tube bridge pier is formed, and armored concrete cap structure is set in pier coping portion；
(3) bearing is installed, and back timber support is installed between the cap structure and Bailey beam of pier coping portion, removes original steel
Rail bearing, and the permanent bearing of installation in situ；
(4) main girder construction, the installation form on the outside of the original Bailey beam of make-shift bridge, casting concrete form concrete structure
Girder；
(5) diaphragm is constructed, after the completion of all main girder constructions of above-mentioned steps (4), in original stull both sides installation form,
Casting concrete, formed and the into a single integrated structure diaphragm of concrete girder structure；
(6) Roadway Construction, the original bridge floor steel facing of make-shift bridge, the colligation between the crossbeam and longeron of original bridge floor are removed
Bar-mat reinforcement, in bridge floor surrounding installation form, pour bridge deck concrete and form beam framework reinforced concrete structure integrated deck in length and breadth,
Finally, back timber support, permanent Bearing Seat Force are removed, transformation is completed.
In the above-mentioned technical solutions, in the step (2), before casting concrete structure bridge pier, in addition to steel pipe column bridge
Pier carries out processing of rust removing, and WELDING STUDS is welded in steel pipe column outer rim section, the colligation steel hoop net around WELDING STUDS, finally will
Bridge pier formwork for placing is arranged on the outer layer of steel hoop net.
In the above-mentioned technical solutions, in the step (4), before casting concrete structure girder, in addition to original shellfish thunder
Beam carries out processing of rust removing, and the colligation girder framework of steel reinforcement in Bailey beam, and finally girder formwork for placing is fixed in Bailey beam.
In the above-mentioned technical solutions, in the step (4), before casting concrete structure girder, reserved at original stull
Beard muscle.
Preferably, in the above-mentioned technical solutions, in the step (5), before casting concrete diaphragm, colligation tabula joist steel
Muscle net welds in stull, and by diaphragm bar-mat reinforcement both ends and beard muscle.
In the above-mentioned technical solutions, in the step (4), original girder is that a plurality of Bailey beam moves towards arranged side by side along bridge
Set, every Bailey beam is spliced by multistage Bailey beam piece, and during casting concrete structure girder, slitting segmentation is entered to Bailey beam
The outsourcing of row concrete is handled.
Beneficial effects of the present invention：Bailey beam make-shift bridge provided by the present invention transform applying for steel reinforced concrete combination permanent bridge as
