Description
Technical field
The utility model relates to bridge construction technical field, is a kind of crack resistance type seamless bridge bridge abutment structure with X muscle.
Background technology
Bridge Abutment shrinkage joint is often brought the maintenance of bumping at bridge-head, stretching device and cause the problems such as the corrosion of substructure containing corrosivity salinity from the infiltration that shrinkage joint is infiltrated, and is that highway at home and abroad bridge continues constant problem demanding prompt solution.The bumping at bridge-head that end of the bridge causes due to stretching device not only causes very large percussion to bridge and road surface, decreases the comfort level of the driving of driver and passenger simultaneously.
Along with the raising of increase and the road speed day by day of the traffic volume, the interruption of communication that maintenance stretching device causes brings very large economic loss.Therefore the series of problems brought at bridge Abutment shrinkage joint is solved imperative.Shrinkage joint place is jumped to the problem of car, have two kinds of resolving ideas: one is improvement stretching device.Current stretching device type is a lot, and its application life is generally within 5 years.But improvement stretching device, does not thoroughly eliminate maintenance and the problem of replacing of stretching device, so improvement stretching device is cured the symptoms, not the disease.Two is the problems fundamentally solving stretching device, by cancelling the stretching device of bridge Abutment.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of the Anti-pull-press performance, shear behavior and the bending resistance that improve abutment, cancels the crack resistance type seamless bridge bridge abutment structure of the band X muscle of the stretching device of Abutment.
The scheme that the utility model technical solution problem adopts is, a kind of crack resistance type seamless bridge bridge abutment structure with X muscle, comprise the abutment built each other, flexible pile, backfill after girder and platform, all bridge deck pavement has been built above described abutment, extension bridge panel has been built and bridge deck pavement is connected as a single entity above described backfill, longitudinal stiffener end downward bending of described bridge deck pavement internal upper part stretches in the gap that girder side and abutment top formed, longitudinal stiffener end of described extension bridge panel internal upper part also bends downwards to be stretched in gap, the described two longitudinal stiffeners stretching into gap cross one another in X-shaped, described girder side is embedded with elastomeric material, embedding between described extension bridge panel and backfill have geotextiles lapping layer.
Further, described extension bridge panel and abutment monobloc cast, be perfused with concrete in described abutment, described extension bridge panel and bridge deck pavement monobloc cast.
Further, in described bridge deck pavement and extension bridge panel, be also embedded with transverse reinforcement, longitudinal stiffener on its top and the transverse reinforcement colligation on top, longitudinal stiffener of bottom and the transverse reinforcement colligation of bottom.
Further, the end stretching into two longitudinal stiffeners in gap described in all outwards bend in hook solid and with the transverse reinforcement colligation on top.
Further, one section is also had additional for improving the bending stiffener of shearing resistance anti-bending strength between the internal upper part stiffener of described extension bridge panel and abutment, top and the bottom transverse reinforcement colligation in described bending stiffener and extension bridge panel, described bending stiffener end is hook solid and stretches in gap.
Further, described elastomeric material is polystyrene material.
Further, the lapping of described geotextiles lapping layer inside is haydite concrete.
Compared with prior art, the utility model has following beneficial effect: on the one hand, extension bridge panel and bridge deck pavement monobloc cast, improve the overall performance of bridge: on the other hand, due to the effect of intersection stiffener, strengthen shear behavior and the cracking resistance of abutment, also abutment top is made to have certain bending resistance, the stiffener that simultaneously intersects also plays the effect of stirrup to abutment top concrete, effectively can suppress the appearance in crack, thus reduce the possibility of bridge floor cracking herein; Moreover outside girder, use polystyrene material layer, received the beam displacement body that part causes due to the temperature difference, the material layer of geotextiles parcel, makes to create space between abutment top and backfill, to this eliminate the soil pressure on abutment top.
