Description
Technical field
The present invention relates to across both wired technical field of bridge construction, and in particular on across both wired old bridge overall pulling down sides
Method.
Background technique
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 on across grade separation net
Empty, span etc. is unable to satisfy driving demand, and it is more universal to need to reconstruct the phenomenon that across grade separation, is increased by reorganization and expansion
Transport power also has bridge of partially both having had been friends in the past to need dismounting newly-built, and the old bridge in part was both wired across below being related to when both wired dismountings
Road traffic safety, difficulty of construction is big, and traditional disintegration, time-consuming for demolition reduction method, effect is low.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide in one kind across both wired old bridge method for dismounting,
The method for dismounting can one piece take down the old bridge beam body, efficient quick, securely and reliably.
The technical scheme is that being across both wired old bridge overall pulling down methods in one kind:
Step 1: crossing the left and right bridge of bridges and culverts according to Bridge Erector stringer across both wired old bridge two sides and periphery place on smooth
Pier on-station position excavates the first carrying foundation pit, the second carrying foundation pit, third and carries foundation pit, and casting concrete supports in foundation pit
Stand；First support frame, the second support frame, third support frame are fixed on the first supporting frame, the second supporting frame respectively
On third supporting frame.
Step 2: the travelling bogie on starting Bridge Erector, Bridge Erector stringer is moved to across both wired old bridge bridges
Contain top, Bridge Erector stringer is then fixed on the first support frame, the second support frame, third support frame upper end；First mentions
Beam trolley, the second bale handle trolley are mounted on the stringer (track) of Bridge Erector.
Step 3: upper across drilling out four perforation circular holes in both wired old bridge both ends beam bodies.
Step 4 step, with the first nut and the first screw rod, the second screw rod, third screw rod, the 4th screw rod, by upper metal beam
It is attached separately to lower metal beam across above and below both wired old bridges on bridge floor；
First sunpender, the second sunpender, third sunpender, the 4th sunpender, which are inserted into, penetrates through circular hole across both wired old bridge both ends
It is interior；By the second nut be separately mounted to the first sunpender, the second sunpender, third sunpender, on the 4th sunpender bottom end screw rod；First hangs
Bar, the second sunpender upper end link are mounted on the first hook below the first bale handle trolley；Third sunpender, the 4th sunpender upper end are hung
Ring is mounted on the second hook below the second bale handle trolley.
Step 5: starting the electric hoist crane on the first bale handle trolley and the second bale handle trolley simultaneously, across both by
After wired old bridge upgrades；Then start the running gear motor on the first bale handle trolley and the second bale handle trolley, walk
Device drives while driving the first bale handle trolley and mobile the second bale handle trolley and moves together across both wired old bridges
Designated position completes the overall pulling down across both wired old bridges on.
Step 6: by across both wired old bridge dismounting is moved to designated position after, metal beam and lower gold in dismounting
Belong to crossbeam, decomposes beam body, and transport place.
Step 7: Bridge Erector is withdrawn from, restoring scene environment.
The Bridge Erector stringer be frame-type stringer, frame-type stringer be equipped with the first stringer and the second stringer, first
Track is housed, the first bale handle trolley and the second bale handle trolley travelling wheel are attached separately to the first stringer and the on stringer and the second stringer
On the track of two stringers.
On the 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 design is reasonable, used device is few, and work progress is safe and reliable, short construction period, economical and practical.
