Abstract
The invention relates to a buffering and absorbing device of vertical temperature deformation of a whole bridge and a construction method thereof. The buffering and absorbing device comprises a metal corrugated plate which can buffer and absorb deformation; the metal corrugated plate is tightly stuck on the back face of a bridge abutment; and a plurality of inched retracting seam material layers, namely pressure releasing strips, are embedded into the metal corrugated plate. The construction method comprises the following steps of: firstly, manufacturing the metal corrugated plate in a factory according to the size of the bridge abutment; embedding a plurality of the inched retracting seam material layers, namely the pressure releasing strips, into the metal corrugated plate; secondly, in a process of constructing the bridge abutment, reserving screws on the back face of the bridge abutment; then, utilizing the reserved screws and fixing a corrugated metal material on the back face of the bridge abutment; and finally, backfilling soil and compacting. According to the buffering and absorbing device disclosed by the invention, driven soil pressure acting behind the abutment in a temperature rising and expanding process is reduced; and meanwhile, the buffering and absorbing device is good for reducing cracks generated between the filled soil and the bridge abutment due to that an upper part structure is contracted in a temperature reduction process.
Description
Technical field
The present invention relates to a kind of energy-dissipating device, be specifically related to a kind of buffering take-up means and construction method thereof of overall bridge longitudinal temperature distortion, the seamless process that it is applicable to middle-size and small-size Integral Abutment Bridge is built.
Background technology
No matter be monolithic or semi-integral bridge abutment seamless bridge structural form, all there is the acting in conjunction between structure-soil in them in fact; The former is the acting in conjunction based on flexible pile or flexible wall and soil, latter be banket after beam-ends and platform between interaction, they all face the problem of a temperature second inner force.Seamless overall bridge is not owing to having shrinkage joint, and therefore it must have the ability of the malformation receiving variations in temperature to cause.When variations in temperature, bridge beam body produces the repeated deformation of certain pucker & bloat.For the bridge of Integral Abutment, because Liang Tai is consolidation, so just in beam body, alternately produce larger axial tension and axial compression; Secondly, upon a drop in temperature, between banketing after the contraction of beam body can cause abutment body and platform, produce gap, again due to the push effect of platform rear vehicle load, banketed filling in this gap, make beam-ends be subject to active earth pressure; Until when temperature rises, beam body produces and expands, and after platform, soil pressure becomes the larger earth resistance of intensity, and total can not be resetted completely, and this just further increases the axial pressure in beam body, is formed as bending component; Thirdly, reciprocal horizontal distortion is there is in the stake top of flexible abutment pile foundation (or body of wall) owing to following beam-ends, stake internal stress increases and easily forms plastic hinge, thus reduce its vertical bearing capacity, the pile foundation of occurred level distortion is under the impact of vertical load simultaneously, to the additional bending moment of geometrical non-linearity be produced, i.e. so-called " P – δ " effect, thus the increase of aggravation Horizontal Displacement.Under this vicious circle, will be stressed very unfavorable to total.
Summary of the invention
In order to overcome above-mentioned technical barrier, by organic application of structural configuration and new material cleverly, construct a kind of buffering take-up means and construction method thereof of overall bridge longitudinal temperature distortion.
One of technical scheme of the present invention is: a kind of buffering take-up means of overall bridge longitudinal temperature distortion, this buffering take-up means comprises the metal corrugated plate that can cushion and receive distortion, described metal corrugated plate is close to the abutment back side, embedded in some very little thick expanded joint material layers, i.e. imperial press strip in the middle of described metal corrugated plate and abutment.Described abutment, metal corrugated plate and imperial press strip form an entirety.
Two of technical scheme of the present invention is: a kind of construction method of buffering take-up means of overall bridge longitudinal temperature distortion, this construction method is carried out according to the following steps: first according to the size of abutment at the good metal corrugated plate of produce in factory, and inside metal corrugated plate, embed some very little thick expanded joint material layers, i.e. imperial press strip; Secondly, time abutment is built, some screws are reserved at the back side of abutment; Again, utilize the screw reserved, metal corrugated plate is fixed on the abutment back side; Finally, backfill tamping.
Beneficial effect of the present invention is: elastic metallic corrugated sheet belongs to the one of elastomeric material, upon a drop in temperature, concrete shrinkage, but due to the elastic deformation of metal corrugated plate, the gap between the metal corrugated plate after abutment body and platform can be made to close, the negative effect that before solving well, active earth pressure is brought; Equally, when temperature raises time, metal corrugated plate can reduce passive earth pressure when temperature rise is expanded after platform by its elastic deformation.In a word, the present invention both can reduce when temperature rise is expanded and acted on the passive earth pressure after platform, to banket and crack between abutment produces when also contributing to reducing temperature drop due to the contraction of superstructure simultaneously.

Referring to Fig. 1, a kind of buffering take-up means of overall bridge longitudinal temperature distortion, comprises metal corrugated plate (elastic waveform stereoscopic metal material) 2, embedded in some very little thick expanded joint material layers, i.e. imperial press strip 1 in the middle of described metal corrugated plate 2 and abutment 3.
A construction method for the buffering take-up means of overall bridge longitudinal temperature distortion, this construction method is carried out according to the following steps:
First according to the size of abutment at the good metal corrugated plate of produce in factory, and inside metal corrugated plate, embed some cun of thick expanded joint material layers, i.e. imperial press strip.
Secondly, time abutment 3 is built, some screws are reserved at the back side of abutment.
Again, utilize the screw reserved, metal corrugated plate (elastic waveform stereoscopic metal material) 2 is fixed on the abutment back side.
