Description
Technical field
The present invention relates to seamless bridge neotectonics and its construction method of a kind of end using arc attachment strap.
Background technology
Bridge expanssion joint is to receive bridge to indulge bridge to due under the cyclic deformation under temperature action and Vehicle Load
A kind of device of length travel, but due to the not enough problem of its durability, jump car problem can be caused to vehicle and reduced driving and relax
Adaptive, and rain penetration, debris filling make expansion joint lose performance and corrode substructure.Also, frequently keep in repair
Maintain and can suspend traffic circuit and raise maintenance cost.As can be seen here, solving the series of problems that brings of bridge expanssion joint is
Imperative.
At present for expansion joint solve problem, generally there are following two thinkings：One is improvement retractor device.Stretch dress at present
Put type a lot, its service life is typically within 5 years, but improvement retractor device, thoroughly do not eliminate the dimension of retractor device
Shield and replacing problem, so improvement retractor device is cured the symptoms, not the disease.Two is fundamentally solving the problems, such as retractor device, passes through
Reduce or cancel bridge expanssion joint and retractor device, due to the retractor device of cancellation Abutment, its attachment strap is except sending out for seamless bridge
Wave outside the effect of seamed bridge attachment strap, also a part of girder is indulged bridge to displacement transfer to adjacent road.Panel type attachment strap is flat
Flush type attachment strap is put by the temperature movement passed over by girder or received by the loop control of attachment strap end seam, for following
Ring control seam, the shift reciprocately brought due to temperature cycles change and material are directly contacted with soil, its durability existing problem.
Content of the invention
The present invention is improved to the problems referred to above, i.e., the technical problem to be solved in the present invention is existing seamless bridge construction
The shift reciprocately that temperature cycles change brings and material are directly contacted with soil, its durability existing problem.
Specific embodiments of the present invention are：A kind of end adopts the seamless bridge neotectonics of arc attachment strap, including seamless bridge
Platform and the embankment filled soil of connection adjacent with seamless abutment, are provided with horizontal attachment strap, the horizontal attachment strap one in the embankment filled soil
On the bracket of seamless abutment, the other end is connected with arc attachment strap to end-rack, and the arc attachment strap is from seamless abutment to embankment filled soil
Direction extends downwardly.State arc attachment strap
Further, through connecting bar connecting between the arc attachment strap and horizontal attachment strap.
Further, the arc attachment strap has buffering froth bed between the end of seamless abutment and embankment filled soil.
Further, the periphery of the arc attachment strap and buffering froth bed is provided with oil immersion fiber cloth.

Further, supercrust is provided with the embankment filled soil.
Further, the horizontal attachment strap is panel type attachment strap or horizontal flush type attachment strap.
Further, the buffering foam layer material is polystyrene foam.
Further, the central angle of arc attachment strap is 45 °.
Present invention additionally comprises a kind of construction method of manufacture above-mentioned end using the seamless bridge neotectonics of arc attachment strap, which is special
Levy and be, comprise the following steps：
（1）When embankment filled soil is constructed to certain altitude, by laying oil immersion fiber cloth and polystyrene foam after fill compaction, this
When embankment filled soil upper surface have leave with arc attachment strap lower surface be adapted profile；
（2）Prefabricated arc attachment strap is placed on above oil immersion fiber cloth, the end position of arc attachment strap and polystyrene foam
Contact；
（3）Arc attachment strap is prefabricated with connection reinforcing bar towards one end of seamless abutment, arc attachment strap towards seamless abutment side
False form is built in setting, prepares the horizontal attachment strap of cast in situs, and false form is stayed towards the end face of seamless abutment with arc attachment strap
There is gap；
（4）The horizontal attachment strap of cast in situs, form removal after the completion of pouring；
（5）Horizontal attachment strap is formed after meeting intensity requirement, fills expansion joint (E.J.), and up lay upper strata oil immersion fiber in gap location
Cloth；
（6）After the completion of the laying of upper strata oil immersion fiber cloth, proceed to banket, until road surface.
Compared with prior art, the invention has the advantages that：The present invention is by burying in panel type attachment strap or horizontal
Entering formula attachment strap rear end and one section of arc attachment strap being added, both are connected with one layer of connection reinforcing bar, a depthkeeping are filled in arc attachment strap end
The foam of degree, wraps up one layer of oil immersion fiber cloth for being easy to its slip around arc attachment strap, and by arc attachment strap in oil immersion fiber
Slide in cloth, the translation that panel type attachment strap or horizontal flush type attachment strap are passed over is converted into rotation, and at connection reinforcing bar
Rotational deformation by connecting the bending of reinforcing bar absorbing.And, arc attachment strap has provided one preferably just to road surface of leading the way
Spend and cross, be conducive to alleviating the generation of differential settlement.
