It is bright, but they do not constitute restriction to the present invention.
As Figure 1-4, the present invention includes bridge deck 1, the substructure 2 of multiple support bridge decks and concrete filled steel tube
Arch, the concrete-filled steel tube arch is symmetricly set in the both sides of bridge deck, and concrete-filled steel tube arch includes the He of main span main arch 3 of half-through
The end bay main arch 4 of deck type, the arch springing at the two ends of main span main arch 3 is individually fixed in two neighboring substructure, the side
Arch springing across the two ends of main arch 4 is individually fixed in two neighboring substructure, close to end bay main arch 4 one on the main span main arch 3
Arch springing on the arch springing and end bay main arch at end close to main span main arch one end is fixed in same substructure, the main span main arch
3 and the span ratio of end bay main arch 4 are 0.3-0.55, preferably 0.43, specific span ratio is decided according to the actual requirements.
In such scheme, bridge deck 1 includes floorings 1.1, crossbeam 1.2 and longeron 1.3, and the floorings 1.1 are supported in
The top of crossbeam 1.2, the both sides of crossbeam 1.2 are respectively fixed with bracket 1.4, and adjacent beams 1.2 are fixed at the two ends of longeron 1.3
Between on relative two brackets 1.4.Floorings 1.1 are concrete slab, and main support is at the top of crossbeam 1.2, therefore floorings are set
Count into height 36cm " π " shape mechanism.Crossbeam 1.2 uses steel box structure, crossbeam 1.2 and the formation steel of floorings 1.1 of steel construction
Concrete Composite Beam, longeron 1.3 uses H-shaped steel construction, and longeron 1.3 is arranged between crossbeam 1.2 by bracket 1.4, crossbeam
1.2nd, longeron .3 and floorings 1.1 coordinate the bridge system structure that light-duty floatation type is integrally formed, and can be effectively improved pushing away for main arch
Power problem.
In such scheme, substructure 2 includes the pile foundation 2.1 being sequentially arranged from the bottom to top, cushion cap 2.2, the and of skewback 2.3
Bridge pier 2.4, the bridge deck 1 is supported in the top of bridge pier 2.4, and the arch springing of the main span main arch 3 and end bay main arch 4 is fixed on skewback
2.3 on.This bridge type is due to being dissymmetrical structure, and foundation level power is slightly larger relative to vertical force, and pile foundation arrangement of reinforcement is more difficult, can adopt
With the pile foundation of major diameter, method that is basic pre- eccentric and using larger concrete frame pier of conducting oneself with dignity is set to be improved.
The pre- bias in basis is the center o of pile foundation 2.11With the cushion cap at the top of it, the center o of bridge pier2Not on same perpendicular, partially
From with a certain distance from.
This bridge type is two bridge girder constructions of asymmetric formula, therefore multiple substructures 2 are included along vertical bridge to being sequentially arranged
The first substructure 5, the second substructure 6 and the 3rd substructure 7, the arch springing at the two ends of main span main arch 3 is individually fixed in
On the skewback of one substructure 5 and the second substructure 6, the arch springing at the two ends of end bay main arch 4 is individually fixed in the second bottom
On the skewback of the substructure 7 of structure 6 and the 3rd.Wherein the first substructure 5 and the 3rd substructure 7 pass through work with bridge deck 4
Dynamic bearing is flexibly connected, and second substructure 6 is fixedly connected with bridge deck 4 by hold-down support (does not show activity in figure
Bearing and hold-down support).
In such scheme, main span main arch 3 is located between the part above bridge deck and bridge deck to be connected by suspension rod 8, is hung
The crossbeam of the bottom hung bridge deck 1 of bar 8, the main span main arch 3 is located between the part below bridge deck and bridge deck 1 by the
One column 9 is connected, the crossbeam of the top braces bridge deck 1 of the first column 9.The main span main arch 3 of the both sides of bridge deck 1 connects with bridge deck 1
Connected between the position connect by the first intercostal crossbeam 11, pass through interval between the main span main arch 3 of the top both sides of bridge deck 1
Multiple first stulls 13 set are connected.
In such scheme, the top of end bay main arch 4 is connected by multiple second columns 10 with bridge deck 1, and the second column 10 is pushed up
Portion supports the crossbeam of bridge deck 1.Pass through second between the position that the top of end bay main arch 4 of the both sides of bridge deck 1 and bridge deck 1 are connected
Intercostal crossbeam 12 is connected, and passes through spaced multiple second stulls 14 between the end bay main arch 4 of the two bottom sides of bridge deck 1
Connection.First intercostal crossbeam 11 and the second intercostal crossbeam 12 are to support one of crossbeam of floorings bottom, because it is arranged on bridge floor
The position that plate is connected with main arch, it plays connection bridge deck both sides main arch simultaneously, therefore forms intercostal crossbeam.Intercostal crossbeam with
Bearing 18 is set between floorings.
In such scheme, the arch rib and the second stull 13 of main span main arch 3 and end bay main arch 4 and the second stull 14 are bilayer
Structure, including section are square four of arrangement supervisors 15, are connected, are responsible for by cross bar 13 and vertical pole 17 between four supervisors 15
Fill concrete in 15.
This bridge-type structure is by main arch, suspension rod, bridge deck (crossbeam, longeron and floorings), bearing, bridge pier, spandrel column, arch
Seat, cushion cap and pile foundation composition.Bridge deck directly bears bridge floor vehicle and Pedestrian Load, and main arch is passed to by suspension rod, or logical
Cross bearing and pass to spandrel column, then pass to main arch；Bridge pier, cushion cap and base are directly passed to by bearing in pier location
Plinth.Suspension rod and spandrel column load are passed to cushion cap and basis by main arch by skewback.The present invention encircles half-through and deck type
Bridge arch is combined, and is combined using a kind of span of asymmetric coordination than organically, forms a kind of unique structure bridge attractive in appearance
Type structure, to meet same site condition requirement not；Bridge deck is using the structural system of light-duty floatation type and the pile foundation of bottom
And bridge pier is engaged, the horizontal thrust of bridge can be improved well, structure is novel, handsome in appearance, reasonable in design, construction party
Just, the harmony of bridge and environment is improved, with good social and economic benefit.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
