Description

Exchanging bridge device and construction method thereof
Technical field
The present invention relates to a kind of exchanging bridge device and construction method thereof, belong to engineering construction technology field.
Background technology
Bailey bridge is to be widely used in the world, a kind of bridge the most popular, and it has simple in construction, convenient transportation, and erection quickly, decomposes the feature of being easy to. Being provided simultaneously with bearing capacity big, structural rigidity is strong, fatigue life the advantage such as length. It difference according to actual needs can form the temporary bridge of all kinds and various uses, emergent bridge and fixed bridge across footpath, has component few, lightweight, the feature that cost is low. Initial Bei Lei army bridge is designed the World War II initial stage in 1938 by Britain engineer. During the Second World War, this military steel bridge is widely used, and after the war, many countries transfer to shellfish thunder steel bridge civilian after some improve, and nowadays, shellfish thunder steel bridge plays irreplaceable effect in transport development, flood-fighting. .
If an application number is that CN204589784U discloses and a kind of is easy to the bridge structure that arched girder is changed, adopt anchor pole from the Upper vertical of the arched girder bottom downward through the cement platform to pier base, be fixed thereon lower two ends with nut; Bridge plate connects in the mutual copline of the horizontal and vertical compression in the surface of arched girder. This utility model beneficial effect, this utility model simple in construction, intensity is big, it is prone to construction, the removable bridge plate laying down its surface when needing to change after bridge damnification, only need during bridge dismounting to remove its internal anchor pole, other structures need not be destroyed and set, reduce difficulty of construction and cost; Bridge plate bears a constant load on the surface of arched girder and reduces the load of arched girder, extends its life-span.
And for example an application number be CN104562924A disclose a kind of bridge pad from jacking backing plate replacing options, after adopting a support arrangement to support bridge superstructure beam body, remove former bearing and pinner, fold in bridge pier pier top or bent cap end face upper strata and be placed through the wedge type block slip realization backing plate from jacking and new bearing, applying pulling force makes the wedge type block of backing plate slide, backing plate jacking, new bearing rises supporting bridge superstructure beam body, and new bearing bears pressure; When bridge superstructure beam body rises to former elevation location, fixing wedge type block, remove a support arrangement, complete bearing replacement; In the bearing replacement process of the inventive method, bridge superstructure beam body not lifting or its absolute altitude only slightly move up and down in the scope of license. The existing jacking of bearing one by one can be prevented effectively from and change the drawback that method needs lifting beam body, causes bridge superstructure to damage.
If an application number is that CN102472025A discloses and a kind of uses the pre-founding materials method and apparatus to replace bridge, this pre-founding materials includes convex and the female connectors of piling bar, steel Concrete Structure cushion cap and metal.Pre-founding materials can deliver to building site for bridge replacement engineering before control the environment of plant in be formed as accurate standard. And, convex and female connectors provide quickly and firmly method connects cushion cap and stake, and do not use welding between stake and cushion cap.
In the area that some remote and mountains are more, large-scale crane is difficult to arrive, and Bailey bridge bridge reaches or service life such as damage etc., it is necessary to changing, be all by artificial disassembling, assembling and replacing at present, speed is slow, and the engineering time is long, has a strong impact on traffic.

2) at crane way crane installed above and directive wheel thereof, make directive wheel and crane realize being synchronized with the movement, then assemble crane again;
3) step 2) all parts installations after carry out crane on crane way and screw mandrel running debugging, check equipment operational reliability;
4) control the top that crane runs to the bridge of damage, then the length according to the bridge damaged, control spindle motor and rotate, drive trolley movement through transfer gear box, thus adjusting to the position being suitable for;
5) control hawser motor to rotate, lower wire rope, until stopping when suspension hook touches the bridge of damage, then at the Bridge position point auger shell pit of suspension hook correspondence damage suspension ring of screwing on;
6) by hook suspension ring, control hawser motor rotation recovery steel wire rope and the bridge of damage is sling and transports transport vehicle rear;
7) being sling bridge to be replaced above transport vehicle again with crane, the position being transported to the bridge damaged is replaced, and when close to bridge pier, point operation control hawser motor is transferred, until installing bridge to be replaced;
8) finally utilizing crane to be sling by the bridge of damage and be placed in transport vehicle, transport vehicle is left, and construction completes.
Beneficial effects of the present invention: this device and construction method thereof are particularly suitable for remote and that mountain is more area, it is possible to the exchanging bridge that quickly will damage, and save duration and cost, practical, are suitable for promoting the use of.
