Description
Technical field
Across both wired technical field of bridge construction the present invention relates on, and in particular on across both wired old bridge overall pulling downs
Method.
Background technology
With the fast development of national communication infrastructure, part existing railway, the highway built up in early days has been not suitable with
Volume of transport demand at present, existing highway, railway Reconstruction Project gradually increase, and cause with putting across grade separation net
Empty, span etc. can not meet driving demand, it is necessary to the phenomenon reconstructed across grade separation is more universal, is increased by reorganization and expansion
Transport power, also there is part bridge of both having had been friends in the past to need to remove newly-built, and the old bridge in part was both wired across lower section during both wired dismountings, is related to
Road traffic safety, difficulty of construction is big, and traditional disintegration, time-consuming for demolition reduction method, effect is low.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided across both wired old bridge method for dismounting in one kind,
The method for dismounting can one piece take down the old bridge beam body, efficient quick, securely and reliably.
The technical scheme is that：It is across both wired old bridge overall pulling down methods in one kind：
Step 1: cross the left and right bridge pier of bridges and culverts just according to Bridge Erector longeron across both wired old bridge both sides and periphery place on smooth
Position position, excavate the first carrying foundation ditch, the second carrying foundation ditch, the 3rd carrying foundation ditch, the casting concrete supporting frame in foundation ditch；
First support frame, the second support frame, the 3rd support frame are fixed on the first supporting frame, the second supporting frame and the 3rd respectively
On supporting frame.
Step 2: starting the travelling bogie on Bridge Erector, Bridge Erector longeron is moved to across both wired old bridge bridges
Contain top, Bridge Erector longeron is then fixed on the first support frame, the second support frame, the 3rd support frame upper end；First carries
Beam dolly, the second bale handle dolly are arranged on the longeron of Bridge Erector（Track）On.
Step 3: it is upper across both drilled out in wired old bridge both ends beam body four insertion circular holes.
Step 4 step, with the first nut and the first screw rod, the second screw rod, the 3rd screw rod, the 4th screw rod, by upper metal beam
It is attached separately to lower metal beam across both above and below wired old bridge on bridge floor；
First suspension rod, the second suspension rod, the 3rd suspension rod, the 4th suspension rod insert to be penetrated in circular hole across both wired old bridge both ends；
By the second nut be separately mounted to the first suspension rod, the second suspension rod, the 3rd suspension rod, on the 4th suspension rod bottom screw rod；First suspension rod,
Two suspension rod upper end links are mounted on the first hook below the first bale handle dolly；3rd suspension rod, the 4th suspension rod upper end link are hung
On the second hook below the second bale handle dolly.
Step 5: start the electric hoist crane on the first bale handle dolly and the second bale handle dolly simultaneously, across both by
After wired old bridge upgrades；Then start the running gear motor on the first bale handle dolly and the second bale handle dolly, walk
Device drives while driving the first bale handle dolly and the second bale handle dolly to move and is moved to together across both wired old bridges
Specified location, complete on across the overall pulling down of both wired old bridges.
Step 6: by after both wired old bridges are removed and are moved to specified location, metal beam and lower gold in dismounting
Belong to crossbeam, decompose beam body, and transport place.
Step 7: Bridge Erector is withdrawn from, restoring scene environment.
Described Bridge Erector longeron is frame-type longeron, and frame-type longeron is provided with the first longeron and the second longeron, first
Track is housed, the first bale handle dolly and the second bale handle dolly travelling wheel are attached separately to the first longeron and on longeron and the second longeron
On the track of two longerons.
On described railway across both wired old bridge beam bodies be precast concrete T-beam or box beam.
Across both wired old bridge overall pulling down methods on the invention has the advantages that, both wired bridges can be rapidly completed
Overall pulling down, across Existing Railway Line normal operation and existing geologic structure do not have an impact on, will not destroy existing bridge
Girder construction.Method for dismounting is reasonable in design, used device is few, and work progress is safe and reliable, short construction period, economical and practical.
