Description
Technical field
The present invention relates to Bridge Rotation Construction Technique technologies.
Background technique
In the construction by swing of bridge, support zone of the slideway as support foot during swivel, in the swivel of bridge
It plays an important role in work progress.The slideway surface layer of Bridge Rotation Construction Technique is made of two-layered steel plates.Wherein lower layer's steel plate into
It is that, again in slideway steel plate bottom casting concrete, will first be finished to concreting after the installation in place of slideway steel plate when row construction
And upper layer steel plate and lower layer's steel plate are welded again after reaching intensity.But since slideway steel plate area is excessive, this construction method is just
There is following both sides in the bonding that will lead to steel plate and its underpart concrete: (1) in concreting process, and steel
Plate be it is horizontal positioned, the bubble of concrete vibrating process light plate bottom cannot effectively be discharged, and lead to concrete and steel plate bottom
It cannot come into full contact with, bond effect is poor.(2) since the concrete of steel plate bottom can not effectively be vibrated, concrete is caused
The leakiness of itself.These two issues can all affect to the bearing capacity of steel plate, in bridge rotating process
In, if the support force of support foot is too big, it will lead to the sinking of slideway steel plate, going on smoothly for Bridge Rotation Construction Technique influenced, when serious
Result even in toppling for beam body.
In construction at this stage, if being bonded in works bottom casting concrete in order to increase concrete and works
Effect mainly uses the following method: (1) by works bottom beveling, being conducive to bubble during concrete vibrating
Discharge.But this just proposes certain requirement to the gradient on inclined-plane, to increase the height of works and fill concrete
Quantity.(2) works and concrete surface are done into hair side, in favor of the bonding of new-old concrete, but this is required first
New-old concrete has to come into full contact with.Both the above method is all improper to the effect control of slideway steel plate construction.Therefore,
A kind of construction that can guarantee slideway steel plate and lower concrete bonding and construction party rule are Bridge Rotation Construction Technique institutes at this stage
There is an urgent need to.
Summary of the invention
The object of the present invention is to provide a kind of slideway steel plates and construction method for Bridge Rotation Construction Technique.
The present invention is a kind of slideway steel plate and construction method for Bridge Rotation Construction Technique, wherein is applied for bridge rotating

The construction method of the above-described slideway steel plate for Bridge Rotation Construction Technique, the steps include:
(1) according to the size of lower layer's slideway steel plate 1, aperture is carried out on lower layer's slideway steel plate 1 according to design；
(2) lower layer's slideway steel plate 1 is subjected to installation fixation by design position, passes through the embedded bar 5 and slideway base of its underpart
Reinforcing bar link together, install fixation procedure in strict control lower layer slideway steel plate 1 elevation of top surface and position；
(3) 1 lower part of lower layer's slideway steel plate and periphery concreting are carried out, hole 2 and the lower layer of vibrating can be passed through in casting process
It is effectively vibrated to the concrete of its underpart on 1 periphery of slideway steel plate；
(4) after concrete vibrating is complete, vibrating hole 2 and 3 position of gas vent suitably supplements concrete, make concrete surface with
1 upper surface of lower layer's slideway steel plate keeps concordant；
(5) it to be conserved in time after the completion of concrete construction, to guarantee that concrete reaches design strength, and reduce coagulation to the greatest extent
The contraction of soil, to meet the needs of rotator construction；
(6) after concrete reaches prescribed strength, the upper surface of lower layer's slideway steel plate 1 is cleared up, it is then sliding in lower layer
Upper layer slideway steel plate 6 is welded above road steel plate, upper layer slideway steel plate 6 is by original design, not aperture.
The beneficial effects of the present invention are: lower layer's slideway steel plate is subjected to aperture, it can be effectively by the coagulation of steel plate bottom
Soil vibrates, and the bubble of concrete surface is discharged.It can not only guarantee the density of concrete, and can guarantee to slide
Effective bonding of road steel plate and concrete.The effect that power transmission is carried out to realize slideway as support leg, ensure that bridge rotating process
Go on smoothly.The structure type of this patent is fairly simple, practical, and will not generation environment pollution, economic benefit is aobvious
It writes, there is good application value.
