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 job practices thereof of whole bridge longitudinal temperature distortion, it is applicable to the seamless process of middle-size and small-size Integral Abutment Bridge and builds.
Background technology
No matter be monolithic or semi-monolithic formula abutment seamless bridge structural form, all there is the acting in conjunction between structure-soil in they in fact; The former be acting in conjunction take flexible pile or flexible wall and soil as main, latter is the interaction between banketing behind beam-ends and the platform, they all face the problem of the inferior internal force of a temperature.Seamless whole bridge is not owing to there is a shrinkage joint, so it must have the ability of receiving the malformation that variations in temperature causes.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 fixed, so just in the beam body, alternately producing larger axial tension and axial compression; Secondly, when drop in temperature, the contraction of beam body produces the gap between can causing banketing behind abutment body and the platform, and owing to the push effect of vehicular load behind the platform, the filling so that banketed in this gap makes beam-ends be subject to active earth pressure again; By the time when temperature rose, the beam body produced and expands, soil pressure becomes the larger earth resistance of intensity behind the platform, and total can not be resetted fully, and the axial pressure that this has just further increased in the beam body forms bending component; Again secondly, reciprocal horizontal distortion occurs owing to follow beam-ends in the stake top of flexible abutment pile foundation (or body of wall), the stake internal stress increases and easily forms plastic hinge, thereby reduce its vertical bearing capacity, simultaneously the pile foundation of occurred level distortion under the impact of vertical load, to produce the additional bending moment of geometrical non-linearity, i.e. so-called " P – δ " effect, thereby 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 cleverly organic application of structural configuration and new material, constructed a kind of buffering take-up means and job practices thereof of whole bridge longitudinal temperature distortion.
One of technical scheme of the present invention is: a kind of buffering take-up means of whole bridge longitudinal temperature distortion, this buffering take-up means comprises can cushion the metal corrugated plate that receives distortion, described metal corrugated plate is close to the abutment back side, embed some cun thick expanded joint material layers in the middle of the described metal corrugated plate, namely driven press strip.Described abutment, corrugated metal sheet and imperial press strip consist of an integral body.
Two of technical scheme of the present invention is: a kind of job practices of buffering take-up means of whole bridge longitudinal temperature distortion, this job practices is carried out according to the following steps: at first according to the size of abutment at the good metal corrugated plate of produce in factory, and at some cun thick expanded joint material layers of metal corrugated plate the inside embedding, namely drive press strip; Secondly, when abutment is built, reserve some screws at the back side of abutment; Again, utilize and reserve good screw, the corrugated metal material is fixed on the abutment back side; At last, backfill and tamping.
Beneficial effect of the present invention is: elastic corrugated metal sheet belongs to a kind of of elastomeric material, when drop in temperature, concrete shrinkage, but because the elastic deformation of metal corrugated plate, can make the slit between the metal corrugated plate behind abutment body and the platform closed, solve well the negative effect that former active earth pressure is brought; Equally, when temperature raises, the passive earth pressure when metal corrugated plate can reduce the temperature rise expansion by its elastic deformation behind the platform.In a word, the present invention both can reduce the passive earth pressure that acts on when temperature rise is expanded behind the platform, when also helping to reduce temperature drop simultaneously since the contraction of superstructure and banket and abutment between the crack produce.
