Description

A kind of construction method of ultra-high performance concrete corrugated steel web plate composite box girder bridge
Technical field
The present invention relates to highway and urban road bridges technology, more particularly, to a kind of ultra-high performance concrete waveform steel abdomen The construction method of plate combination box beam bridge.
Background technology
The Concrete Thick web of conventional concrete box beam is replaced using Wavelike steel webplate, forms box girder with corrugated steel webs, no Only structure is moulded attractive in appearance, while avoids the problem of conventional concrete box girder web ftractures, excellent in durability, therefore big It is widely applied in middle span bridge.
Compared with traditional concrete box girder, because the torsional rigidity and anti-distortion rigidity of box girder with corrugated steel webs section have Reduced, so the width of box girder with corrugated steel webs should not be too wide.In general, the cast-in-place box beam or ripple of single box single chamber Shape steel web plate composite box girder Breadth Maximum is no more than 5m, and broader single case box beam will form single box double room by increasing web quantity Or single-box multi-cell section, or apply lateral prestressing tendon, to adapt to the requirement of bridge width, avoid floorings stress excessive, So result in and the increase of beam body weight occur, difficulty of construction increase, the problems such as concrete is not easy to pour into a mould.
UHPC(Ultra High Performance Concrete, ultra-high performance concrete)It is a kind of high intensity(Tension Intensity is more than 7MPa, compression strength is more than 150MPa), high-durability New Style Concrete Materials.The high performance feature masters of UHPC It is the hardening of stress and stretching strain, that is, produces the behavior for being similar to the surrender of steel tension, the UHPC mechanics of appropriate arrangement of reinforcement Performance is close to steel construction.In current level, show for the advantage in this major design engineering of such as bridge, made Obtaining overall structure outward appearance tends to be light and handy, and amount of reinforcement is reduced, and some engineerings even eliminate reinforcing bar.
Using UHPC materials, bridge member can reduce physical dimension, tend to be very thin frivolous, so as to reduce deadweight, improve knot The efficiency of structure resistance load and the span ability of increase bridge, while lift, set up conveniently.Therefore, by traditional Wavelike steel webplate Box beam and ultra-high performance concrete(UHPC)With reference to, prestressing force ultra-high performance concrete Wavelike steel webplate continuous box girder is formed, it is right Solve existing prestressed concrete continuous box girder bridge cracking in webs and deadweight is larger, the problem such as construction complexity is significant.
The content of the invention
It is an object of the invention to provide a kind of construction method of ultra-high performance concrete corrugated steel web plate composite box girder bridge, The combination box beam bridge of the present invention had both possessed the advantages of traditional box girder with corrugated steel webs bridge, had again from heavy and light, the distribution of floorings load Ability is good, box beam reverses the series of advantages such as distortion effect is small, makes single chamber bridge floor overall width up to more than 10m, and box beam Main member can be completed in precasting yard, and Contraction in Site is few.
To achieve the above object, the present invention can take following technical proposals:
The construction method of ultra-high performance concrete corrugated steel web plate composite box girder bridge of the present invention comprises the steps:
The first step, it is prefabricated often across the U groove structure part of box beam by Bridge Design requirement:In precasting yard by Wavelike steel webplate In place, and thereon, weld stud connector on lower flange, then the pre- of box beam bottom plate is fixed in precalculated position on stretching bed seat Stress reinforcing bar is simultaneously stretched to design load, then assembling reinforcement net, pre-buried top plate prestress pipe, sets up template, pours into a mould very-high performance Concrete, it is prefabricated including bridge floor side plate, box beam bottom plate, Wavelike steel webplate, diaphragm plate U groove structure part, wherein bridge floor side plate Upper pre-buried suspension ring;Then steam curing, form removal after 48 hours are used;
Second step, according to plate in the distance between the prefabricated bridge floor side plate of U groove structure part of the first step prefabricated bridge floor:Tie up Wire-tie net, pre-buried top plate prestress pipe, set up template, and in pre-buried suspension ring thereon, lateral connection reinforcing bar, longitudinally connected steel Muscle, ultra-high performance concrete is then poured into a mould, and with steam curing, form removal after 48 hours;Plate total thickness 0.2m in bridge floor after shaping ~ 0.5m, bottom is with longitudinal and transverse T-shaped ribs staggeredly;
3rd step, construction abutment, bridge pier, plate in prefabricated U groove structure part and bridge floor is lifted in place, colligation horizontal stroke successively To connection reinforcing bar, a complete box beam is formed after pouring laterally wet seam;
4th step, next bridge pier of constructing is then in place by second box beam lifting, by the Wavelike steel webplate of adjacent box beam Be welded as a whole, and the longitudinally connected reinforcing bar between the adjacent box beam of colligation, then pour longitudinal wet joint between adjacent box beam or Cast-in-place crossbeam, form continuous bridge structure;After the concrete poured reaches design strength value, tensioning is located in top plate and in advance should Prestressed strand in hydraulic piping;
5th step, the 4th step is repeated, complete the continuous bridge structure of multispan.
The first step is prefabricated often when the U groove structure part of box beam, and 5m is smaller than between adjacent two diaphragm plate.
Compared with prior art, its advantage is embodied in construction method of the present invention:
1)The present invention uses ultra-high performance concrete material(UHPC), component tends to be slim in physical dimension, conduct oneself with dignity compared with Traditional box girder with corrugated steel webs reduces about 15-25%;
2)The box beam top plate of the present invention(Plate in bridge floor)It is made, can be filled of ultra-high performance concrete material with box beam bottom plate Divide high tensile, the anti-compression property using UHPC;Box girder web uses Wavelike steel webplate, can make full use of its excellent shear resistance Energy.
3)The box beam top plate of the present invention(Plate in bridge floor)The deck structrue with the short longitudinal rib of T-shaped and the short cross rib of T-shaped is employed, Load-carrying efficiency is higher than traditional rectangular section box beam top plate, and load distribution capability is good, and box beam transverse width can reach more than 10m;
4)The present invention, across being provided with more intensive diaphragm plate in box beam, makes the good integrity of box-beam structure, box beam often Torsion distortion effect it is small;
5)The box girder bridge of the present invention uses the construction technology of precast assembly, on the one hand due to using the solidifying soil of very-high performance coagulation Material, make the concrete component of box beam more frivolous, be easy to lifting construction;On the other hand, the main member of box beam(U-lag knot Plate in component and bridge floor)It can be completed in precasting yard, Site Template and cast-in-place construction workload are few, are easy to the quick frame of bridge If;
6)The box beam baseboard prestress of the present invention uses pretensioned prestressing, than traditional post-stressed waveform steel abdomen The live steel Shu Zhangla workloads of slab box beam are few, and construction is convenient.
To sum up, the present invention has box beam from heavy and light, small, floorings the load distribution capability of torsion distortion is good, constructing sets up The series of advantages such as convenient.Box beam uses the ultra-high performance concrete with high-durability to pour into a mould, the good endurance of structure, especially Had broad application prospects on big-and-middle across footpath bridge.
