Description
Technical field
This utility model relates to a kind of extension bridge panel bridge construction structure adopting fine sand to fill.
Background technology
Jumping car and the secondary adverse effect (such as the additional internal force of structure, the corrosion etc. to structure of leaking) damaged due to expansion joint and produce that bridge expanssion joint brings are the thorny problems that current domestic and abroad bridge is frequently encountered in reality is operated.Bridge and road surface are not only caused very big percussion by the bumping at bridge-head caused due to retractor device, but also can reduce the driving comfort level of driver and passenger.Additionally, along with the increase day by day of traffic flow, safeguarding of retractor device is often caused serious interruption of communication with changing, and then produces huge economic loss.As can be seen here, the series of problems that solution bridge expanssion joint brings has been imperative.For the solution of expansion joint problem, generally there is following two thinking: one is improvement retractor device, but it does not thoroughly eliminate maintenance and the problem of replacing of retractor device, cures the symptoms, not the disease；Two is by reducing deck expansion installation or cancelling bridge extension joint, the problem fundamentally solving retractor device.
At present, seamless bridge common in the world includes overall bridge, semi-monolithic bridge and extension bridge panel bridge, and wherein the extension bridge panel bridge scope of application is the widest.Extension bridge panel bridge refers to the seamless bridge adopting extension bridge panel abutment.Extension bridge panel abutment refers to floorings and strides across the expansion joint being provided with between parados and girder, couples or cross the abutment that parados couples with corbel back slab with parados.Expansion joint is still had between girder and abutment parados, but jointless on floorings, also expansion joints.Extension bridge panel bridge is less to suffered constraint rigidity at vertical bridge due to girder, so the girder axial elastic deformation that variations in temperature causes is only small, the flexible of beam body guides itself and joint of leading the way into mainly through extension bridge panel.Comparing with general seamed bridge, extension bridge panel seamless bridge can reduce construction and the maintenance cost of bridge, simplifies the construction of bridge, improves the driving performance of bridge, improves durability and the anti-seismic performance of bridge.
Extension bridge panel in extension bridge panel bridge, according to conventional construction method, need to lay Traditional Wood template or steel form as bed die, for cast in situs extension bridge panel concrete.But after concreting, bed die cannot be removed, not only causing material resources waste, template is permanently present as unnecessary component simultaneously, it is possible to create cause the hidden danger that joints is abnormal.If not laying Traditional Wood template or steel form as bed die, in the concreting process of extension bridge panel, concrete easily drops from the expansion joint between abutment parados and girder, makes the concreting of extension bridge panel to complete.According to the flexible material such as asphalt felt, galvanized sheet as bed die, due to flexible material insufficient rigidity, vibrate process influence for concrete own wt and scene, easily cause the expansion joint between extension bridge panel bottom surface concrete parts or total blockage abutment parados and the girder at the expansion joint place between abutment parados and girder, and then affect the vertical bridge of extension bridge panel bridge girder to flexible, cause that extension bridge panel bridge girder and extension bridge panel are subject to extra pulling force and ftracture.
