Detailed description of the invention
To be described in further detail the utility model embodiment below.
Integral bridge of the present utility model is traversing changes girder system system, its preferably detailed description of the invention be:
On exist curves bridge pier direction across bridge axis, inserted to play one arranges steel pipe pile and interim bridge pier one, and the traversing slideway of exist curves is installed on exist curves bridge pier, steel pipe pile and interim bridge pier one, exist curves superstructure is placed on the traversing slideway of described exist curves;
At the new bridge pier of lower structure of exist curves, and inserted to play one arranges steel pipe pile and interim bridge pier two on new bridge pier direction across bridge axis, and the traversing slideway of new bridge is installed on new bridge pier, steel pipe pile and interim bridge pier two, new bridge superstructure is placed on the traversing slideway of described new bridge;
Described exist curves superstructure and new bridge superstructure are connected into entirety by connecting elements, and jack is set in the outer end of the traversing slideway of new bridge.
There is back seat the outer end of the traversing slideway of described new bridge, and the outside of described new bridge superstructure is provided with connecting pin, and the cylinder bottom of described jack is against on described back seat, and cylinder bar is connected on described connecting pin.
Integral bridge of the present utility model is traversing changes the method that girder system system realizes changing beam, comprises step:
On exist curves bridge pier direction across bridge axis, inserted to play one arranges steel pipe pile, in order to install the traversing slideway of exist curves;
On new bridge pier direction across bridge axis, many inserted to plays one arrange steel pipe pile, in order to install the traversing slideway of new bridge;
Exist curves superstructure and new bridge superstructure are connected into entirety, simultaneously traversing pushing tow;
Under circuit operation condition, New Bridge is constructed complete, then exist curves superstructure is connected together with new bridge superstructure, within the time period that operating line short-term is closed, by traversing for new bridge superstructure to design bridge location while, exist curves superstructure is shifted out beyond bridge location, realizes new bridge at short notice and be on active service.
Integral bridge of the present utility model is traversing changes girder system system, can in short-term---within being generally a few hours or within a couple of days---under the condition suspended traffic, quick-replaceable new bridge.
Know-why of the present utility model is:
Beyond the safe distance that the upstream or downstream that need the exist curves changed are certain, and on the axis parallel with line midline, under the not affected condition of guarantee exist curves normal operation, assembled good new bridge superstructure in advance.Exist curves superstructure and new bridge superstructure are connected into entirety, and install pushing tow jack in the side, rear in new bridge superstructure horizontal sliding direction, a jack installed by every pier.All jack are connected to pumping plant control centre, and pumping plant control centre can ensure all jack synchronization jobs.Then short-term closed-loop, is separated the superstructure of exist curves with circuit, and by new bridge superstructure pushing tow to design bridge location place, exist curves superstructure just leaves place on line simultaneously.New bridge can begin one's duty.Then can remove original bridge and construction equipment after circuit operation, complete exchanging bridge.
Specific embodiment:
As shown in Figure 1 and Figure 2, comprising: exist curves superstructure 1, new bridge superstructure 2, exist curves sliding crossbeam 3, new bridge sliding crossbeam 4, existing bridge pier 5, new bridge pier 6, interim bridge pier 1, interim bridge pier 28, connecting elements 9, back seat 10, connecting pin 11, jack 12, pumping plant control centre 13.
Under circuit normal operation uninterrupted traffic condition, at exist curves both sides inserted to play steel pipe pile, i.e. described new bridge pier, interim bridge pier one, interim bridge pier two.Existing bridge pier and interim bridge pier one arrange described exist curves sliding crossbeam, new bridge pier and described interim bridge pier two arranges described new bridge sliding crossbeam, material is thus formed the sliding rail of exist curves and new bridge.
Described exist curves superstructure and described new bridge superstructure are fixed by described connecting elements, connects into entirety.
Described back seat is set at the rear of the sideslip direction of described new bridge sliding crossbeam, described connecting pin is set in the side, rear of the sideslip direction of described new bridge superstructure, described jack is connected on described back seat and described connecting pin.
