Description
Technical field
The present invention relates to traffic bridge technical field of buildings, particularly room formula access bridge and combinations thereof formula viaduct.
Background technology
As the automobile pollution in each city increases year by year, congestion in road difficulty of governance and town road build pressure by
Year aggravation, the setting such as subway, elevated overpass link urban traffic pressure is all being built in a lot of cities, by facts have proved laying
Elevated overpass is to administer one of traffic above-ground congestion best bet, but a lot of reasons governs building for urban interchange
Make, trace it to its cause in terms of mainly including following four：
1st, building viaduct needs to carry out full width or half range road closure, and road closure generally requires the 1-2 year, and car is caused on narrow road surface
Current inconvenience, is declined by efficiency and is further exacerbated by congestion.
2nd, viaduct is bulky, is to realize three-dimensional multi-direction current often design-build over long distances and the drawing of more number
Bridge, the distance of access bridge is long not only to hinder the appearance of the city, and seriously increases the engineering time.
3rd, building viaduct needs in advance well-digging stake, and well stake quantity is many and close, it is easy to supply water below urban road, combustion
Gas, communication pipes intersect, and construction environment complex jamming is many, easily damage other pipelines, increase difficulty of construction and time further.
4th, single bridge investment generally requires several ten million yuan, and its access bridge construction accounts for the 70% of total operating expenses, costly cost
Greatly.
Content of the invention
The present invention solves the deficiencies in the prior art and provides a kind of room formula access bridge that construction is quick, with low cost, combination is various
And combinations thereof formula city arch steel structure viaduct.
The technical solution adopted for the present invention to solve the technical problems is：
Room formula access bridge and combinations thereof formula viaduct, including main bridge and access bridge, the access bridge includes that access bridge road surface and room formula support machine
Structure, access bridge road surface bottom arranges multiple room formula supporting mechanisms, and room formula supporting mechanism is made up of eaves, house beam and body of wall.
Host bridge includes arch steel structure reversed beam, cambered road panel, bridge post and bridge pier, the arch steel structure reversed beam bag
Reversed beam interior lining panel, reversed beam arch sheet, reversed beam curtain plate and crossbeam is included, is provided between the reversed beam interior lining panel and reversed beam curtain plate
Horizontal reinforcing plates, lower horizontal reinforcing plates and vertical reinforcing plates, the reversed beam arch sheet two ends are located at formation arch on little tension board,
Connected by big tension board between reversed beam arch sheet, big tension board top is by supporting transverse slat and supporting riser and cambered road panel
Connection, big tension board bottom is connected with crossbeam, is provided with bridge pier connecting plate, adjacent crossbeam between adjacent arch steel structure reversed beam
It is provided with lateral connection bolt and longitudinally connected bolt.
Centre gangway is provided between the room formula supporting mechanism, on body of wall, opens up import and export, passway respectively, import and export logical
Cross passway to connect with centre gangway；Body of wall bottom arranges body of wall and amplifies foot；Eaves sidepiece is provided with eaves end face connection reinforcing bar, leads to
Cross welding eaves end face connection reinforcing bar both sides eaves link into an integrated entity, body of wall amplifies foot sidepiece and is provided with amplification foot connection reinforcing bar,
By amplifying foot connection reinforcing bar, body of wall amplification foot in both sides is linked into an integrated entity；Room formula supporting mechanism is provided with electric wire through-hole and lifting
Hole.
Access bridge road surface both sides arrange crash barrier and mounting seat, and mounting seat is provided with guard rail, and access bridge road surface is provided with
Expansion joint.

The present invention has the beneficial effect that：
1st, the present invention has used for reference building building technology, works out room formula access bridge and combinations thereof formula viaduct.Using room formula access bridge knot
Structure is no longer rely on stake fixed bridge body of digging a well, and no longer needs when building access bridge to carry out full width or half range road closure, generally requires 7 days.Carry
High road passage capability, is greatly decreased construction congestion.Room formula access bridge can pass through in the prefabricated rear hoisting transportation in building site to construction ground
Amplifying foot increases access bridge stability, prefabricated jacking pocket under bridge pier, when pier sinking or position adjustments with jack light and
The jack-up that easily lifts is padded.Pontic safety is effectively ensured, is particularly suitable for yellow soil horizon of collapsibility use.
2nd, the realization left-hand bend necessarily Long span construction that arch steel structure reversed beam can be both economical, is reducing pontic thickness
The length of access bridge is shortened while degree, deadweight, the pontic slope control that connects is 8%.Reduce bridge floor stress torque, it is possible to
Reach that pontic is thick, across footpath big, from heavy and light, eliminate the well-digging stake for building viaduct routine on this basis.According to pressure etc.
In pressure divided by compression area formula, on the basis of existing bituminous paving bears automobile pressure, overstriking bridge pier simultaneously sets up amplification
Foot, and the envisaged underneath reparation special jack seat in bridge pier, when setting of ground, can jack-up bridge pier padded, tiltedly
Top can also shift, and this is the best approach for administering no well stake viaduct disadvantage.The approximate rainbow of the shape of arch viaduct is graceful beautiful
See, the functional parts such as protective plate, baffle are set up, also can be publicized as advertisement position, the viaduct through dressing up can more be formed
One of city landscape.
3rd, bridge construction is no longer rely on stake of digging a well, and construction is greatly reduced with engineering equipment, and construction costs is greatly reduced, constructs
Technical threshold reduces, can prefabricated, can lift, installs soon, can move, shockproof, can be greatly lowered and invest and the duration.Room
Storehouse, switchgear house, office etc. can also be made in son, just in case there is setting of ground, can be padded with jack-up house.Underground piping has
During problem, mobile trenchless rehabilitation can be removed at any time.
4th, Xue Peng ensure that northern area winter driving safety, and snow canopy has preferably blocked sleet, and the gradient of viaduct is carried
10% is risen, the length of access bridge can shorten, fault-tolerant amount of designing and constructing increases.While setting up snow net further, road surface is effectively prevent
Roll repeatedly to form frost zone through automobile, pre- anti-slip.
Particular technique parameter is as follows in sum：
1st, construction-time significantly shortens, and round-the-clock job just can complete pontic construction for about one week.
2nd, operating expenses reduces 70%.
3rd, track quantity can be built as needed.
4th, the main gradient 8%, is easy to vehicle pass-through and construction needs, and shortens access bridge length.
