Description
Technical field
This utility model belongs to technical field of bridge construction, especially relates to a kind of Large-Span Continuous girder span building up station rotator construction cradle bottom and wraps up platform.
Background technology
China railway construction is in gold period, and large quantities of Lines for Passenger Transportation, inter-city passenger rail in succession go into operation and come into operation. The special technical requirement of Line for Passenger Transportation, causes it can not adopt usual friendship mouth as common railway. The thing followed be the increase in Line for Passenger Transportation across existing railway in operation main track, railway station, highway construction, the crossing construction cycle is long, and Business Line Influence to operation is big, and potential safety hazard highlights.
Bridge Rotation Construction Technique is the ball pivot and slideway and turntable structure that utilize coefficient of friction only small, and with simple equipment, the huge bridge structure in both sides that will have built, integral-rotation is installed and put in place. Zhanyi County's grand bridge and Zhang Jiatian grand bridge are Shanghai elder brother's special line for passenger trains Yunnan Section weight difficult point engineerings. Zhanyi County grand bridge total length 1768.386m, this bridge 27#��30# pier with (72+128+72) rice continuous beam with 25.3 �� of angles of cut across station, running railway line Zhanyi County, cross over 6 station tracks; Filling according to original position is outstanding, main span projects 105 meters and is positioned at both wired tops, affects the cycle longer. And (60+100+60) the rice continuous beam set up on the long 898.563m of Zhang Jiatian grand bridge full-bridge, this bridge 15# pier��18# pier with 40 �� of angles of cut across station, running railway line Gui-Kun Railway Malong, cross over 5 station tracks; Main span projects 66 meters and is positioned at both wired tops, affects the cycle longer. Wherein, the girder of above-mentioned two bridge is the In Reinforced Concrete Box Girder being inclined cross existing railway station and its beam body is single box single chamber, And of Varying Depth, variable section structure, in girder, the height of 0# block (being namely supported in the beam section directly over bridge pier) is 10m and its top bottom width degree respectively 12m and 7.1m, top bottom width degree respectively 12m and the 6.7m of other sections beam body, closure section box beam height is 5.5m, and bridge cantilever section list T structure weight is 8600 tons.
In practice of construction process, because of many across both wired electric railways, station continuous beam quantity on the elder brother's special line for passenger trains of Shanghai, risk source is numerous, potential safety hazard is excessive, adopt rotator construction, the driving to railway can be reduced and disturb, shorten the influence time to railway and station. But turn in station, span is big, beam body Heavy Weight, and risk is high, and the duration is tight, and difficulty of construction is big. When large-span continuous beam is carried out rotator construction, thus beam body length is longer and crosses over building up station, thus large-span continuous beam is generally divided into former and later two beam body turn respectively, former and later two beam body are constructed in the left and right sides of crossed over building up station respectively, after having constructed, former and later two beam body are turned respectively, after former and later two beam body are all turned and put in place, former and later two beam body need to be joined the two sections of a bridge, etc (i.e. midspan closing). When former and later two beam body are constructed, Hanging Basket is generally adopted to construct. Because of construction area distance building up station close together, for guarantee both Wired Security, normally use, Hanging Basket need to be protected.
Traditional basket protection method is protected for adopting protecting canopy frame, because protecting canopy frame length length and span are big, setting up frame equipment and cannot be introduced in the station of operation, station track spacing is too small, without frame basis, and set up with in demolishing process, the security risk at station is very big at frame. Wrapping up basket protection structure it addition, in the past complete, adopt full steel structure, Heavy Weight and steel using amount are big. Hanging Basket is protected by reality, and cradle bottom protection is particularly important. Thus, need to design a kind of simple in construction, reasonable in design, wrap up platform from heavy and light and easy construction, Large-Span Continuous girder span building up station rotator construction cradle bottom that result of use is good, adopt steel and wood composite structure can cradle bottom effectively be protected, and steel using amount is few.
