Description

A kind of continuous rigid frame bridge closure segment pushing tow top board pushing tow system and construction method thereof

Technical field

The invention belongs to technical field of bridge construction, especially relate to a kind of continuous rigid frame bridge closure segment pushing tow Roof Push away system and construction method thereof.

Background technology

Continuous rigid frame bridge is the continuous bridge of pier consolidation, point main span be the multispan rigid frame bridge of continuous beam and many Span Continuous- Rigid frame bridge, all uses prestressed reinforced concrete construction, has a main pier of two or more, uses pier consolidation system, have T-shaped rigid frame bridge and The advantage of continuous bridge.Closure segment is the key link of continuous rigid frame bridge construction, for reducing the operation phase due to concrete shrinkage Xu Become and the variations in temperature adverse effect to bridge structure, during the construction of continuous rigid frame bridge closure segment, typically use very heavy at closure segment Top pushing tow, applies horizontal jacking force (according to being constructed respectively to closure segment both sides (the specifically cantilever beam section of closure segment both sides) Continuous rigid frame bridge across footpath with close up front temperature, applied horizontal jacking force typically at 80t～150t, indivedual documents record to be adopted Horizontal jacking force be 800t), adjust bridge internal force status, to eliminate construction time temperature and long-term concrete shrinkage and creep shadow Ring.

Nowadays, the tectonic sieving of continuous rigid frame bridge closure segment pushing tow and temporary locking is various informative, and general many employings are just Property support structure (also known as stiff skeleton) combines the closure segment part interim stretch-draw of steel bundle and enters line-locked mode, at closure segment coagulation Soil forms be rigidly connected (also referred to as false closure) before pouring.The most employings of stiff skeleton are built-in, i.e. stiff skeleton and pushing tow dress Setting within concreting face, completely including stiff skeleton after closure segment concreting, stiff skeleton is as permanent Structure retains.After this structure stretch-draw, built-in stiff skeleton share part axial compressive force, be conducive to reducing closure segment concrete Local compressive stress, but the later stage is due to the impact of concrete shrinkage and creep, and between stiff skeleton and concrete, compressive stress will progressively weigh New distribution, stiff skeleton will absorb the major part compressive stress from prestressed strand, thus be easily caused closure segment coagulation soil pressure and answer Power deposit reduces, and increases cracking risk.

In view of the foregoing, use external stiff skeleton (outer rigid support structure) in recent years more.External strength Property skeleton be positioned at beyond concreting face, belong to temporary component, closure segment concreting is removed after completing, and is not involved in long-term Stress；It is characterized in that internal force is fully transferred to be undertaken by closure segment concrete in early days, compressive stress deposit abundance.

The T structure (also referred to as T structure cantilever beam) of continuous rigid frame bridge closure segment both sides uses the construction of Hanging Basket cantilever pouring due to more, because of And measure, monitor, formwork erection, stretch-draw etc. the most all can produce error, normally behave as following three after the various accumulations of error The error of the situation of kind: the first, height variation, i.e. closure segment two ends exist the discrepancy in elevation；The second, lateral deviation, i.e. closure segment two ends exist There is deviation on direction across bridge, between the bridge longitudinal axis at closure segment two ends, there is deviation；3rd, torsional deflection, i.e. closure segment The box beam at two ends is asymmetric, exists with the beam center of gravity (the i.e. longitudinal center's axis) torsion as axle.

During practice of construction, the continuous rigid frame bridge being positioned partially or entirely on horizontal curve, due to two coxostermum steel bundles configuration and The size difference of web length, is easily generated above-mentioned the second and the third deviation；For the bridge closed up several times, the more later stage closes The closure segment held together, produce above-mentioned the first, the probability of the second and the third deviation the biggest.

Theoretically, closure segment two ends cantilever pouring construction quality, progress and construction monitoring are carried out, and typically do not have by mistake The situation that difference requires beyond construction technique normalizing, but practice of construction often has dimensional discrepancy close more greatly and exceed code requirement model Situation about enclosing, now, can cause certain adverse effect to structure, such as hogging moment bundle and close up the prestress pipe deviation of bundle relatively Greatly, pipeline concrete stress state can be made during stretch-draw uncontrollable, even result in Local Cracking；Regular reinforcement connects tired After difficulty, and connection on the most same axis, also concrete local can be had a negative impact under External Force Acting, increase cracking wind Danger.Therefore, it is necessary to excessive deviation is corrected on the premise of affecting bridge structure internal force status not too much, also referred to as top Push away correction.

Wherein, for the elevation difference at the first closure segment two ends above-mentioned, can be fitted by the method for uneven preloading Working as adjustment, concrete adjustment process is as follows: in closure segment concrete pouring construction, and general employing other weight such as water tank or sandbag enters Row counterweight, does not consider the half often holding counterweight amount to be closure segment weight concrete when the discrepancy in elevation adjusts, along with concrete construction progressively Unloading, i.e. suitably adjusts elevation difference by the counterweight that cantilever two ends are different.But it is to above-mentioned the second and the third deviation, existing Nowadays there is no a set of corresponding correction method of adjustment.

During it addition, use outer rigid support structure (such as external stiff skeleton) to carry out pushing tow, jacking force should be first before applying Base plate and top board at closure segment are provided above preburied component, and implement pre-buried in last cantilever pouring stage.Wherein, even Continuous steel bridge folding section (also referred to as girder closure segment) refers to the beam section carrying out closing up in the girder of continuous rigid frame bridge, i.e. continuous rigid frame The binding site of bridge girder, including end bay closure segment and main span closure segment.

But more the pre-buried base of existing top board, use to weld U-shaped connection reinforcing bar below steel plates and reinforcing bar is imbedded top board and mix Technical scheme in solidifying soil, there is following defect in the program: the first, top plate thickness is limited, and common u-shaped connects reinforcing bar radical relatively Few, base is low with top board bonding strength；The second, U-shaped connection reinforcing bar reinforcing bar original with box beam top board can not fully be combined；The Three, large-area steel plate causes bridge floor leveling layer and pave-load layer concrete to be connected the weak band in formation local with top board end face；4th, Member Welding workload is big.It addition, the pre-buried base of existing top board, also have and use shaped steel vertically to insert in concrete as pushing tow The technical scheme of counter-force point, there is following defect in the program: the first, pushing tow point position is higher, and pre-buried base local concrete is subject to Power, in addition to the shearing in pushing tow direction, still has bigger moment of flexure to need shaped steel and periphery concrete to undertake, is unfavorable for giving full play to mix Solidifying native measuring body characteristic；The second, need to excise the part shaped steel of prominent top board after incremental launching construction completes.

Nowadays, when continuous rigid frame bridge closure segment is carried out pushing tow, the most all it is not provided with special reaction frame, but passes through Pre-buried shape steel bracket takes into account reaction frame as base, also has and is directly connected to rigid bracing (outer rigid support by pre-buried base Structure) method, pushing tow cuts away the part affecting concrete of bridge deck paving again after completing, but above-mentioned existing arrangement and method for construction is equal There is following defect: the first, locking and pushing tow position is positioned at the middle part of outer rigid support structure, due to jack to be arranged Causing the middle part structure complexity that outer rigid support constructs, the integral rigidity of outer rigid support structure reduces；The second, locking is adopted With Site Welding, after construction trouble, and welding locking, error is difficult to adjust；3rd, pushing tow and concreting need to cut after completing Cutting dismounting, recycling rate of waterused is low；4th, component gravity center is higher, and during pushing tow, additional bending moment is big.It addition, continuous rigid frame bridge is closed up During Duan Jinhang pushing tow, it is common that apply longitudinal jacking force；In indivedual bridge construction process, also can there is lateral deviation and reverse partially Difference (i.e. construction error), now needs to be rectified a deviation by oblique pushing tow.But at present, lack the counter-force that can carry out oblique pushing tow Frame, it is impossible to carry out oblique pushing tow.Wherein, lateral deviation refers to continuous rigid frame bridge in deviation present on direction across bridge, reverses partially Difference refer to continuous rigid frame bridge anisopleual and exist centered by beam longitudinal center axis the torsion problem of line.
